Introduction
Ecological change, a vital issue in today’s world, has gained much importance in recent years, has many components, and requires international cooperation. Deforestation is one of the most important components of ecological change and has recently become a controversial issue of current research[1] with the deforestation in the tropical region. As also seen in the FAO statistics, in the years between 1990-1995 deforestation was mostly experienced in such countries situated on the equatorial belt as Brazil, Indonesia, and Zaire.[2] However, deforestation has not been a major concern of only the modern world or the last century; the concern on deforestation goes back long in history. Therefore, the history of the deforestation should be researched documented for a better understanding of its present conditions, as in all issues whose roots lie in the past.
Deforestation is usually defined as the loss of forest. FAO defines deforestation as converting forests to another land use or the long-term (more than 10 years) reduction of tree-canopy cover below the 10 percent threshold. Depending on how it is estimated, over 15 million ha and a half of natural forest is lost in the tropics every year. This is more than the area of Nepal or Arkansas in the United States.[3] It is a wellknown fact that mankind has destroyed the forests on earth since the discovery of fire. Depending on the increase in population, vast areas of forests have been destroyed for different reasons: for agriculture and opening grazing lands, for heating, obtaining energy for mining, accommodation, for opening roads, hunting, for keeping safe from wild animals and giving harm to the enemy during wars.
Eight thousand years ago at the advent of sedentary agriculture, forests covered approximately 40 per cent of the world’s land area or about 6,000 million hectares. For the next 7,500 years, farm and pasture lands gradually crept into the forests, covering the most fertile, most accessible soils. The areas mostly affected were the Middle East, the Mediterranean watershed, South Asia, and the Far East. Forest removal in Mesopotamia and the Mediterranean Basin was well advanced in pre-Christian times. Those forests that do remain are in many cases badly degraded. For example, in Turkey, in the forests of Pinus brutia only the tallest, the straightest trees have been selectively cut for centuries.[4] Relying on different assumptions on this issue, it can be said that about 8-10,000 years ago (c. 8-10,000 years BP) 50 % of the earth was covered with forests, whereas today this amount has drawn back to about 30 %, most of which can even be said to have lost originality. In this regard, it can be concluded that in the last 10,000-15,000 years, with the effect of human activities, half of the forests in the world have been destroyed.[5]
The destruction of the middle belt forests in Europe which began in the Mesolithic and Neolithic eras and continued until today by gradually speeding up has always been one of the main subjects of attraction for researchers. The tens of thousands years of deforestation in this belt occurred in Central and Western Europe especially in the 200 years following 1050 AC.[6] Deforestation, which continued in the following years, became intense and extensive in the world particularly from the middle of the 19th century on. “Between 1850 and 1980, 15 per cent of the World’s forests and woodlands were cleared. The world forest area has now shrunk to 3,500 million hectares as a consequence of human exploitation, most of which occurred in the latter half of the 20th century”.[7]
It is possible to say that the long-lasting and most extensive deforestation occurred in the old settlements of the world, particularly in the Middle East and its surroundings, depending on their history and increase in population. Anatolia shared the same fate and faced deforestation from its early times. Though the reasons of this deforestation can be anticipated from the climactic, geomorphologic, geologic and soil characteristics of Anatolia, no research has been conducted to put forward these reasons with the allegation that there are no or enough data on the issue. According to M. Williams, knowledge about the worldwide deforestation is not too much in the past. Thus, past deforestation of Anatolia is defined as “dark ages and dark areas”[8] , as M.Williams emphasizes it.
The findings of the researche on the vegetation of Anatolia indicate that 10,000 years ago (c. 10,000 years Before Present), in early Holocene, a vast area of land was covered with steps of trees in the surroundings of the salt lake in Central Anatolia and in the Southeast Anatolia. Apart from this, all other parts of Anatolia were covered with various kind of forests. Until the c. 5,000 years BP, the structure of the land did not change much, and the only change that took place was the expansion/spreading out of the steps of trees. Until about 8,000 years ago, with the foundation of many Neolithic settlements in Anatolia, mankind began its ominous effect on nature. In this regard, the anthropogenic effects began 5,000 years ago, which means that in the change of vegetation cover in nature humanity has been playing the major role for 5,000 years. As found, the forest areas around Lake Beyşehir, Lake Söğüt and Lake Köyceğiz were destroyed, and with the influence of excessive grazing the existing steps in Central, Eastern and Southeastern Anatolia were well expanded.[9] A study on the Roman Classical Period indicates that Turkey’s Western and South coastal regions that are barren or degraded today had vast forest cover.[10] According to the findings of the palynological researches done in a limited area, the forest areas are observed to gradually get wider in the period between 12,000 and 4,000 years ago. However, in the last 2,000 years, a serious withdrawal in the forest cover is seen due to the extreme human intervention and exploitation of natural resources. This withdrawal is much more outstanding in the last 500 years.[11]
Though deforestation has taken place in time in all the places of Anatolia where there is human existence, it has taken place especially in the Central, Eastern and Southeast regions of Anatolia which have continental climate and in which the rainfall is inadequate. Since the forest areas in these regions could not renew themselves because of the climatic conditions, they became steppes due to the destruction that had taken place throughout history. As a result of this process, which still continues, the regions under consideration are today almost deprived of forests. However, the forests on the coastal regions, depending on the adequate rainfall and appropriate climatic conditions, could renew themselves and have continued their existence until the present, though they are scanty when compared with the past. This is why in these regions the most qualified trees and forests occupy the largest space in Anatolia.[12]
Even today, Turkey is quite suitable for the growth of rich vegetation in terms of climate, geomorphology, soil and the other conditions. In terms of the number of plant species (8,472), the number of endemic plant species (2,711) and the amount of endemism (32 %), Turkey is the richest country of the Mediterranean basin.[13] In normal conditions, apart from some areas in Central, eastern and Southeastern Anatolia, about 70 % of Turkey should have been forest areas. Taking into consideration the fact that forests occupy only 26 % space, it can be said that a large amount of forest areas were destroyed from the time human beings began to live in Anatolia until the present.[14] The major difference between them originates from the fact that forests could not renovate themselves after the deforestation in the deep past, depend on the forests could not renovate themselves in the inner region where the continental climate sway. When the related literature is investigated, it is seen that there are few studies on the deforestation in Anatolia,[15] and these studies do not focus on Anatolia but investigate it together with its surrounding[16], that is, Europe[17] or the Middle East.[18] When we analyse from the deep past to the period of the Ottoman Empire, it is evident that the situation isn’t different and present studies are in the form of publication of Ottoman archival documents.[19] It is noteworthy that in the studies on the 16th century the issue is handled with respect to the increase of population and it is said that in order to meet the nutritional needs of the increasing population, new agricultural areas should be opened, the only way of which is to destroy forest areas.[20] However, none of these studies focus directly on deforestation and the term is even not mentioned.
This study aims to show that it is possible to access proof of deforestation in the 16th century and, relying on this proof, to investigate the reasons of deforestation, the ways it occurred, its extent and the effect of the increase of population in this period on it. However, due to the multiplicity of the documents belonging to the 16th century,[21] only those studies and archival documents on certain regions of Anatolia are investigated, and though the issue is taken against the background of the whole of Anatolia, the focus is essentially on the example of Hüdavendigar (Bursa) sancak/ liva. [22] This field has been chosen for study because detailed archival documents on it belonging to the 16th century were published. Moreover, due to its nearness to Istanbul and the ability of its forests to renovate themselves, it has undergone deforestation in all periods, and thus it is possible to find proof of deforestation for all historical periods in it.
This study is the first on deforestation in the 16th century, one of the centuries in which great increase of population took place in the history of settlement and population in Anatolia; it is even an introduction to deforestation in Anatolia in the past.[23] In this article, firstly, an overview of deforestation in 16th century Anatolia will be given, and then the extent of deforestation in that century, in which the greatest increase in population took place, will be presented. Since there is no possibility of scanning all the archival documents for the whole of Anatolia, in the context of Hüdavendigar Sancak will be examine in detail the purpose of deforestation, locations and size of deforestation and some issues related to the population growth. After that this subject will be examined in detail in the context of Hüdavendigar Sancak, in addition to this detail it will be analysed for the whole of Anatolia by giving examples from the other parts of Anatolia. As there is no study for other period of Anatolian History, this study is important and it will make a small contribution to the studies for the whole world in terms of environmental change in the past. In other words, the outlines of one component of environmental change, which has occurred up to now, will be illuminated generally.
Deforestation Data in the Ottoman Archival Documents
As mentioned briefly above, the forests of Anatolia have been subject to deforestation by humans from early times. However, to have access to data of the deep past is hard, and, if any, since they are indirect and undetailed, it is difficult to take any clear knowledge from them, if any. In contrast, the data of the period under consideration can be said to be clearer and to include more definite knowledge. Thanks to the documents belonging to the Ottoman period, we have the chance to access clearer and much more definite knowledge on the deforestation in the 15th and 16th centuries.
The documents used in this study are primarily tahrir defters.[24] The other documents used are such sources belonging to the 16th century in the Ottoman archives as mühimme defters (the defters in which important Divan (Ottoman Imperial Council) decisions are recorded), kanunnames (code of laws), and şeriyye sicils (kadi court records).[25] This variety of sources on the whole of Anatolia is also valid for Hüdavendigar sancak. The fact that the mufassal (detailed) tahrir defters used for the sancak are already translated to today’s letters[26] much facilitated the collection of data for this study. However, it should be noted here that in Hüdavendigar sancak tahrir/survey was done in three different years (1487, 1521 and 1573), and that though there is no problem in the 1521 and 1573 tahrirs/surveys, there are some defects in the original version of the 1487 tahrir defter, and the same defects are also present in its published version. Hence, as will be seen below, the numbers belonging to the year 1487 are generally not taken into consideration. As a matter of fact, the tahrir defters do not present direct numerical data on the issue. However, as those on other issues, the data were recorded, as exemplified below, indirectly and so that they could be representative of the whole field in terms of deforestation. The data used in the present study are obtained by counting the indirect records under consideration one by one.
Though the terms and explanations derived from these documents regarding the issue are recorded in a standard and organized way according to the aims of their preparers, they are easy to collect if some time is spent on it. Actually, the handling of the issue in the archival documents is in accordance with the approach of contemporary historians, who take the issue in terms of opening new agriculture areas for collecting taxes rather than of deforestation. Although such terms and explanations in these documents, especially in the tahrir defters, as ‘balta yeri’ ‘baltalık’, ‘ormandan açılub’, ‘kuhiden açılub’, ‘genden tarla açmak’ do not have standard meanings, generally speaking, they mean opening grazing and agriculture lands by cutting trees and clearing bushes.[27]
The subject studied in this article is expressed in the tahrir defters and other documents with the following terms and explanations:
‘taşın ağacın arıdub’, ‘bir yerün kimesne kökün sökse’, ‘sonradan kütiğin söküb açılan yerler’, ‘kendü baltasıyle sahib-i arz marifetiyle açub tarla idüb yiğirmi yıldan berü ziraat eyledüği yerleri’, ‘bu yirde oturanlar kendüler baltalarıyle çalısun kurub açdıkları yirden öşr virmeyeler’, ‘[bir raiyyet] baltasıyle yeni bir [yer] aça öşrin raiyyet sahibi alur’, ‘baltalarıyle açdıkları tarlanın öşrlerin dahi kendü sipahilerine virirler’, ‘baltası ile feth idüb hasbeten lillah zaviye mamur etmiş’, ‘balta açuğu’, ‘kuhi ve ormanlar açılub ziraat olınsa’, ‘kuhiden açdıkları yirleri’, ‘mezraa[28] … kuhiden ihya etmek şartıyle verildüği tafsil olındı’.[29]
As can easily be seen, all these terms and explanations in different documents express deforestation, that is, the cutting of trees and the destruction of forest cover.
In the 1653 Sofyalı Ali Çavuş code of laws (kanunname), there are articles that do not presuppose punishment for those who establish settlements by cutting trees from forests. For instance, in one article it is said: “if latecomers or nomads open agriculture areas or establish new settlements as village or mezraa (temporary settlements for agriculture) in steppes, woodlands and mountains by destroying forests or cutting trees, such settlements are called ‘hariç-ez defter,” (When some people were discovered to be not recorded during the tahrir, they were later recorded in a new defter, which was called hariç-ez defter [not recorded in the register]).[30] As can be observed, the article does not presuppose a certain punishment for the above-mentioned people, but to prevent their flight from tahrir (and thus to make them pay taxes), they were recorded in hariç-ez defter.
In the Hüdavendigar liva tahrir defters, though there is no standard in the data relating to the subject, the data include explanations that are adequately informative. The relevant records detected in the Defters that form the basis of this study are recorded as follows:
‘ormandan açılmış yerlerdir’, ‘genden açılmış yerlerdir’, ‘baltaları ile açtıkları yerlerdir’, ‘kuhiden ve genden açdukları yerler’, ‘kendü baltasıyla açmıştır’, ‘dağdan açılmış ziraata kabil yerler’, ‘yeni açılmış yerdir’, ‘sonradan açılmış yerdir’, ‘baltalarıyla açtıkları ormanlıkların öşri alınmıya’, ‘dağdan açdıkları yerler’, ‘dağdan ve bayırdan açılmış yerler, ‘genden ve kuhiden açılan yerleri ziraat edenler’, ‘raiyyet yerlerinden ve müsellem ve piyade çiftliklerinden gayri ormanların ve ağaçların baltalarıyla açdukları yerlerin kanun-ı kadim üzere öşürleri alınmıya, deyü buyurulmuşdur’, ‘çayırdan bazı sökülüb ziraat olunub’, ‘kendü baltaları ile açdukları yerlerine sipahi taifesinden kimesne dahl etmiye, öşrlerin ve rüsumların almıya’, ‘dağdan ve genden açılmış yerler, ‘genden ve kuhiden açılan yerlerinin dahi öşür rüsumın sipahi alur’, ‘kendü baltasıyla açılmış, nim’, ‘Çayır-ı Kazık, evvelde koru imiş’, ‘kuhiden açılmış yerler: İshak açması ve Duran açması ve Cafer b. Mustafa açması’, ‘Osman kışlası, kûhiden açılmış yerdir’, ‘Halayık ormanında genden açılmış yer’, ‘Küçük orman ve büyük orman mezraaları genden açılmış yerlerdir’ (pp. 81-474).
As seen, except one term and explanation, the terms and explanations recorded in the Hüdavendigar liva defters are undoubtedly all associated with deforestation. The only exception is the term ‘gen’, which is open to discussion. However, as seen below, the fact that it has alternative definitions makes this term less problematic for the purpose of this study. It is possible to have different understandings of the term ‘gen’ that frequently takes place in the tahrir defters. In the Tarama Sözlüğü, ‘gen’ is defined as an empty space, an unpluoghed and unsowed field, a field not touched by humans.[31] Likewise, in the Derleme Sözlüğü, it is defined as: “an area not sowed, ploughed or touched for a period of time and thus covered with bushes; a field opened from an untouched area.[32] In the Dictionary of Turkish[33], it is defined as a field that is left empty without being sowed for a period of time, and in Redhouse as: ‘wide, loose, abundant, much’.[34] When we take these definitions and the knowledges in the tahrir defters into consideration, the generally accepted definition of the term gen can be said to be: ‘a raw piece of land or a prairie made appropriate for agriculture by clearing the bushes, trees and grasses on it’.
In the defters we have investigated, there is information supporting this definition of gen. For instance, the expressions “kuhiden ve genden açtıkları yerler, Halayık ormanında genden açılmış yer, Küçük orman ve Büyük orman mezraaları genden açılmış yerlerdir, dağdan ve genden açılmış yerler (the places they open from kûhi and gen; the place opened from gen in the Halayık forest; small and large mezraas are places opened from gen; the places opened from gens and mountains)” both indicate that gen and forest are used interchangeably and express that gen is an opened area in a forest. Furthermore, as will be seen below, when an area in the region on which Hüdavendigar liva exists is left unsowed, due to the the climactic conditions and the amount of rainfall, bushes and trees grow on it by themselves in a short time. Such expressions in the defters as ‘dağ yeri olup ziraat olunmamağla orman olmuş’ (‘ [it is a] mountainous area that became a forest because it was not cultivated) (p. 252)’, ‘evvelde koru imiş, haliya mezraalıkdan çıkub Hazret-i Hüdavendigar korusu olmuş (it was previously covered with bushes, but now it has ended up being a cultivated piece of land and become the bush of the Sultan at present) (p. 219), and so on indicate that the area becomes a forest when left empty and unsowed. Relying on these definitions and explanations, the term gen is taken in the present study as the proof of deforestation.
Deforestation in the Hüdavendi̇gar Sancak
As has been the case for other states and societies, besides the deforestation done for naval and mining purposes and for satisfying other public needs, in the Ottoman state we come across-the kind of deforestation done by people throughout history. In the Ottoman period, opening agricultural lands, the stockbreeding activities of settled or semi-settled people, the cutting of trees for settlement, for the production of instruments and for fuel requirements, and forest fires, all played their role in the destruction of forests.
It is also known that, one of the main reasons of deforestation results from socioeconomic structure of the Ottoman Empire. There is no forestry consciousness in the Ottoman society in today’s context, just like other medieval societies in the Middle East. In contrast to agriculture areas that were valued for their revenue generating function, forests were regarded as nothing more than ‘reserve places’ that could be used when needed. In accordance with the bullionist economical system employed in the Ottoman state[35], one of the most important incomes of the state was the taxes collected from the public, and thus the economic politics of this state were based on always increasing the tax amounts in the classical Ottoman Period. In the documents, it is even frequently emphasized that one of the main duties of those doing tahrir/ survey was to increase the amount of collected taxes[36]. When this point is handled according to the purpose of this study, in this period it is seen that the forests were left open to public use and to the use of the state whenever needed, and for that reason, a flexible and a somewhat indefinite regulation was applied to the forests.[37] Keeping these conditions in mind and taking into consideration the increase of population in this century, the record in the documents of the gradually increasing deforestation towards the end of the 16th century becomes more understandable.
As a natural result of the economic system, in addition to the opening of grazelands and areas for agriculture for more income, the promotion of people or institutions that established settlements also had an ominious effect on forests. For instance, the presence in the documents of such expressions as “raiyyet yerlerinden ve müsellem ve piyade çiftliklerinden gayri ormanların ve ağaçların baltalarıyla açdukları yerlerin kanun-ı kadim üzere öşürleri alınmıya, deyü buyurulmuşdur (in accordance with the ancient law it was ordered that people pay no tithe for the areas they open in forests with their axes except for the farms of the tax-paying subjects and those of the auxiliary foot soldiers (p. 180)”, and “kendü baltaları ile açdukları yerlerine sipahi taifesinden kimesne dahl etmiye, öşrlerin ve rüsumların almıya (sipahis (cavalrymen) should not intervene in and collect taxes and tithes for the places people open with their axes)” (p. 221) indicates that people in special positions as derbendci[pass-guards], köprücü [bridge-keepers], zaviye ve tekke [dervish hospice] servants (these are some of the privileged groups that are exempt from paying tax due to the particularity of their jobs) were regarded as exempt from paying taxes when they established settlements in forests. These expressions also explain the paradoxical situation in the data when it says some people pay taxes when they do deforestation while some others are exempt from paying taxes.
To handle the issue in the context of Hüdavendigar sancak after these introductory explanations, it is better to give some information on the administrative system to make the issue more understandable. It is at least necessary to understand what is meant by ‘Hüdavendigar sancak’ (Figure 1). The smallest administrative unit in the Ottoman administrative system, depending on an administrative structure going back to old times, was the village, whose borders were certain.[38] Up to 50-100 villages/karye formed a subdistrict/nahiye, the co-existence of sub-districts formed districts/kaza, of districts sancaks/ livas (sub-provinces) and of sub-provinces the provinces/eyalets/beylerbeyiliks/states.[39]
Hüdavendigar sancak (sub-province) (Figure 1) is situated in the northwest of Anatolia, along the southeast coast of the Marmara Sea, roughly speaking, in the area called Bthynia in ancient times and Bursa province today. As this sancak corresponded to the area where the Ottoman state was founded, it was the first administrative unit and the administrative core of the state. The sancak did not have geographical integrity and thus was characterized with the intervention of other sancaks to its borders, which was in a way caused by its being the administrative core of the state. Though changed in different historical periods, according to the 16th century documents, with its about 15,600 km² area, the sancak was one of the largest/greatest ones in the period. The sancak included a total of 14 districts (kaza), one of which being the center, 14 towns, 1,457 villages, 530 mezraas and more than 2,000 settlements (including temporary ones). As a matter of fact, the districts and areameter of the sancak frequently changed after its establishment, and became somewhat fixed, as others in the whole of Anatolia, only with the 17th century.[40]
In the south of the sancak, there is Uludağ and to its east the western part of the Köroğlu mountains. In terms of climate, it is situated in a passageway for the Mediterranean climate from the west, the black sea climate from the north and continental climate from the east, and so its climate shows the effects of the three climates.[41] When handled with regard to agricultural activities and vegetation cover, the area is quite appropriate in terms of rainfall and temperature for vegetation cover, and thus the climactic conditions make the growth and renewal of vegetation cover possible. The forests existing in the area on which Hüdavendigar sancak is situated surpass the average forests in Turkey. These forests are regarded as good in quality and include fir, poplar and juniper trees along the southern side of Uludağ; Abies bornmulleriana (Uludağ köknarı), Pinus nigra, Populus tremula, and Juniperus nane. On the other hand, over the places near the Coast of Marmara Sea quercus, Pinus brutia, tilia, fagus and fagaceae trees are spread, while the lower parts are covered with maquis types. In short, in the area there is a rich vegetation cover with forests consisting of quercus, Pinus nigra, Pinus sylvestris, Pinus brutia, Abies, juniper, fagus, fagaceae and carpinus trees.[42]
As can also be seen below, the forests surrounding the Marmara Sea, due to their being close to İstanbul, were constantly exposed to deforestation from the foundation of the Ottoman state onwards. Especially, the Bolu-Izmit-Bursa forests that cover a large area in the southern and eastern parts of the region were used for naval purposes until the middle of the 19th century and faced deforestation to a great extent.[43] Affirming this fact, the name of the ‘Gemlik’ town situated in this area, in which the Ottoman state was founded, possibly mean a place where ships were made and came from the word ‘gemilik’ (meaning ‘shipment’, ‘the building of ships’).
Hüdavendigar sancak is an administrative unit containing the city of Bursa, which remained as the second greatest city of the Ottoman Empire (the first being İstanbul) throughout the Ottoman history. As can also be observed in the table below (Table 1), while the population of the city of Bursa consisted of 6,190 household in the year 1521, in 1573 it increased to 12,832 household. Apart from the city of Bursa, the population of the districts increased in the given years from 6,642 to 26,699 household, and that of the whole sancak (sub-province) from 20,037 to 39,531 household. Relying on the method Darby[44] proposed for England and Barkan[45] for the Ottoman, the total population can approximately be calculated by multiplying the number of household with the coefficient ‘5’.[46] According to this calculation, the total population in Hüdavendigar sancak in 1521 was about 100,000, while in 1573 it increased to approximately 200,000. In brief, these numbers indicate that the population in the sancak was doubled in 52 years, which means that the forests were doubly damaged as more and more forests were destroyed for opening grazing and agriculture lands, for satisfying the increasing population’s energy, heating and accommodation needs, and for producing equipment.
The subject of population increase, which is the main reason for deforestation, can be clearer and more interestingly presented by comparing the total population of the sancak with that of the villages where deforestation occurred. As seen in the the table below (Table 2), while the percentage of the change of the population over the sancak[47] from 1521 to 1573 was 1,97, that in the villages where deforestation occurred was 2,45. In other words, the population in the villages where deforestation occurred increased faster than the total population of the sancak in general, which is the very reason of the destruction of forests in these villages.
Besides the increase in the number of households, there is another piece of evidence that supports the role of population in deforestation. This is the fact that the number of what is recorded in the defters as mücerred - men who were single and did not own a land - increased faster than the household owning a land. As seen in Table 2, while the increase rate of the total population of the sancak is 1,97, it is 2,74 in the population of mücerred. When the same values are compared with the villages where deforestation occurred, it is noteworthy that both values are higher in the villages (the increase rate of the household is 2,45 and of the mücerred 4,55). In fact, the studies on not only Hüdavendigar sancak but on all Anatolia of the period have demonstrated that the population of mücerred increased quite fast towards the end of the 19th century.[48] According to the Ottoman law, the mücerreds had to get married in order to be able to own land, and, since there was an increase in the population, they were given lands when married either by dividing the already existing lands into smaller parts or by opening new lands in natural areas. When the tables and explanations above are taken into consideration, it can be observed that in Hüdavendigar sancak both processes, the increase of population and deforestation, worked concurrently. As can be understood from the greater increase of population in the villages where deforestation occurred, the forests were destroyed to a greater extent in the places where the population increase was higher than others.
It is possible to indicate the pressure of population on land, that is, the opening of new lands for the increasing population also in the Hüdavendigar sancak tahrir defters. The subject will be better understood when the number, quality and approximate width of the agriculture areas recorded in the defters are investigated. When the following tables (Table 3 and 4) are observed, it is seen that in the year 1521 there were 1,931 çifts[49] (çift=holding farm) and 2,012 nim çifts (half a çift) in the sancak, while in 1573 the number of çifts decreased to 1,641 as the number of nim çifts increased to 2,451. On the other hand, the number of ekinlü (married peasants in possession of 1/3 a çift) decreased in 1521 from 2,341 to 2,031 as the number of bennak (married peasants in possession of ¼ a çift) jumped from 2466 to 8056. These numbers indicate that, similar to what is already said about the Larende district,[50] holding farms whose division was strictly prohibited according to the Ottoman law[51] were divided. As a matter of fact, the division of land supports the thesis of this study not directly but indirectly. However, when the table below is observed, newly-obtained lands can be seen to exist beside the division of the already existing ones. Otherwise, it would be difficult to explain the expansion of the total agriculture land in the sancak. Furthermore, the newly-obtained lands do not include the agriculture lands that were acquired through deforestation and that we handle here in detail relying on zemin[52] records.
In addition to the numbers of çifts, the thesis of this study can also be reinforced by presenting the spatial measurement of çifts, that is, by dwelling on their areameter. Relying on the information given in the kanunname of Hüdavendigar sancak, it is possible to broadly say that ‘a çift is 100 acres, nim çift is half of the çift, ekinlü 1/3 and bennak ¼ of a çift.’[53] If we accept all the çifts in Hüdavendigar sancak as medium in quality, that is, if we take the evsat (medium) çift as 100 acres (1 acre = 920 square meters),[54] we can derive the conclusion that in Hüdavendigar sancak there was a total of 3988200 square meters (398,8 ha) agriculture land in 1521 and a total of 5,113,360 square meters (511,3 ha) in 1573. These values indicate that the total agricultural land in the sancak extended 1,125,160 square meters (112,5 ha) in 52 years, and this number becomes more when the space records in the defters and the destroyed areas are added to it.
It is possible to support the explanations above also by investigating the increase rate in the size of the land in the given years. When for a clearer and easily understandable comparison we change all the agriculture lands to the size of a çift (as shown in Table 5), it can be seen that there were approximately 4,335 çift across the sancak in 1521, while -with a 1,28 increase- this number was 5,558 in 1573. However, when the increase rate in the villages where deforestation occurred is investigated, in the given years the 512,8 çift number can be observed to have increased to 772,3, which means that the increase rate was 1,50. In terms of areameter, the increase was from 471,776 to 710,516 square meters, and this indicates that the increase rate of land in the villages where deforestation occurred, as is the case of the population increase rate, surpasses the general rate across the sancak. In other words, the increase rates of the population and the land take place concurrently, and the existing agriculture and grazing lands were expanded to the disadvantage of forests for meeting the needs of the surplus population.
As for animal husbandry as one of the main reasons of deforestation throughout history, tracing the records of grazinglands opened for animal husbandry in forests and thus the role of husbandry in deforestation in the Ottoman archives was impossible since no taxes were paid for grazinglands. However, though they do not definitely state it, the archives indirectly suggest the increase in the number of animals and the way this increase harmed to forests because, as it was in all periods, new grazinglands were opened not in the already existing agricultural lands but by giving harm to forests. Moving from this point, relying on the amount of tax taken for sheep and goats throughout the sancak (one akçe for two sheep or goats) and on the records of the collected tax in the kanunname, the number of animals in the sancak can be put forward as in the following table (Table 6). When the numbers in the table are observed, it is seen that while in 1521 the number of animals in the sancak was 15,986, this number increased to 39,830 in 1571. Therefore, this means that the forests were more and more exposed to deforestation and pressure for feeding the fast growing number of animals in the sancak in this 52-year period of time.
As some defects are observed in the defters in the records of data concerning animal husbandry in the villages, as it is in the records of husbandry all over the sancak, a table was given in the present study to show the numbers related to husbandry in the villages where deforestation occurred. However, it is useful to underline a factor that attracts attention during the investigation of the defters. Firstly, the number of domestic animals in 1487 is seen to be higher than that in 1521. Secondly, in contrast to these two tahrirs, an obvious increase is observed in the last tahrir both in the villages dealing with husbandry and in the number of domestic animals.
When the records concerning this issue in the defters are investigated in the light of the information given above, it is seen that though there are no references to deforestation in the first tahrir of 1487 and the second tahrir of 1521, the last tahrir, that is, the one related to 1571 is full of such references. As a matter of fact, such references to deforestation began to be recorded not only in the Hüdavendigar sancak but also in all other sancaks from the mid 16th century. It is worth note that the date when deforestation began to be recorded was also that in which the population increase trend got faster and internal migration became more intensive[56] in Anatolia. When the documents are investigated in detail, though not concerning Hüdavendigar sancak, it is possible to find earlier deforestation records related to the whole of Anatolia. However, when the studies conducted are observed, it is seen that deforestation occurred most in the period, that is, in the mid 16th century, when the pressure of the population over area was more than ever before.[57]
To accept the tahrir records as factual, it is seen that there are 259 reference records of deforestation in 250 out of 2,041 settlements in Hüdavendigar sancak (Table 7). The fact that there is more than one record for some areas has led to an inbalance between the number of residences and the number of references. When all the references to deforestation are taken into consideration, deforestation records are observed to exist in 12,2 % of the residences all over the sancak. The district in which the reference record number is highest is Taraklu (60), which is followed by Beypazarı (39), Akyazı (27), İnegöl (25), and Göynük (18). When the following map (Figure 2) is investigated, these districts can be observed to be in the northern and northeast parts of the sancak, that is, along the mountainous terrains covered with forests. While deforestation mostly occurred in the forests in such districts as Taraklu, Beypazarı, Akyazı and Göynük, that is, those along the western extensions and southern side of the Köroğlu mountains, less deforestation is observed to have occurred, as in İnegöl, in the districts on the sides of Uludağ. It is noteworthy that the districts (such as Beypazarı, Yenişehir, Göynük, and Akyazı) where deforestation mostly occurred simultaneously have the highest population in terms of households.
Although the extent of deforestation in the places where forests were damaged was either not explicitly recorded or not recorded at all in the defters, the officials who did the tahrir gave some information which can be of help for calculating the area in some places (totally in 113 different places) (Table 8). Apart from such units as çift, nim çift, resmi-i çift (a land tax) and resm-i zemin (the tax for space) whose size and tax amount were specified in kanunnames, there were also lands named as mudluk, kilelik, dönüm, and zevle, all of which were smaller than çift and called in words indicating their area scale.[58] Even a certain tax collected in some places was sometimes recorded as a different tax in the name of nakdiye (cash). Although it does not seem possible to give the total areameter scale of the places where forests were damaged due to the different records and the indefinite proportions of these places in the records, a certain value can be determined depending on the scanty information given concerning the places in which deforestation occurred. When the table below is observed, it is seen that the total size of the area that faced deforestation was equivalent to 19 çift -which means 1,748,000 square meters (174,8 ha)-. Depending on kanunnames, it is also possible to easily determine the areas specified as resm-i çift (tax for çift) and resm-i zemin (tax for space/area) (526,056 m²/52,6 ha). Similarly, when the total areameter scale of the mudluk ve kilelik places is calculated as 963,847, 2 m²/96,3 ha, the total scale of the areas in which deforestation occurred and on which information was given can be said to be 32,379,032 square meters (323,7 ha) in total. Supposing that the areas of the other 146 references whose units are not specified are not less than this value, the total area scale of damaged forests can be claimed to be two or three times higher than the one calculated here. This number may seem small at first glance and unimportant for a sancak that was 15,600 square kilometers. However, this number can be seen to be quite high when we take into consideration the facts that this number occurred in 52 years, which is a short time in natural history, that it is impossible for the forests damaged for agriculture and grazinglands to renovate themselves and that this period of time expressed a process that began before and continued afterwards.
When the deforestation over the sancak is treated in terms of district and the population and area changes are investigated together, it is possible to arrive at the conclusions outlined in the following table (Table 9). As seen in the table, the greatest change in households took place in the districts of Ermenipazarı, Yenişehir, Yarhisar and Akyazı, while the greatest change in the population of mücerred is observed to have taken place in Domaniç, Akyazı, İnegöl, Geyve and Akhisar. As there had not been any decrease throughout the century neither in the household nor in the mücerred populations, the change rate was always above “1”. However, observing the presence of values less than/below “1” in the area change rate, it is worth noting that there occurred decreases instead of increases in the area rate. The most important change in the rate of sowed and ploughed land is observed to have occurred in the districts of Ermenipazarı, Yenişehir and Göl, while the least change occurred in Akhisar, Göynük, Taraklu, Geyve and Beypazarı, in which, as can be understood from the values less than “1”, there had been a decrease in agriculture lands.
The fact that deforestation did not occurr in most of the districts in which the greatest population increase took place should not be taken as a paradox to the general argument of this study. The correlation between deforestation and population increase sometimes does not seem to exist in the recorded data because the officials who did the tahrir were not always meticulous when taking the records or because things that occurred repeatedly were sometimes recorded as a whole to avoid registering the same things again and again. Such correlation may sometimes seem not to exist also because the administrative borders of the districts were not definite and sometimes villages that were related to one district in the first tahrir were related to another district in the second tahrir, which is an important challenge for the researchers conducting research on these districts and villages to cope with. In addition, the fact that no tahrir was done in the sancak in the 52 years between 1521 and 1573 caused some facts during this period of time to be overlooked, such as recording lands opened by damaging forests as agriculture lands-especially when a long time passed from the opening of the land to the tahrir. Therefore, the rarity of the deforestation in the district where the population and agriculture lands greatly increased and where there was a forest cover points to the fact that either deforestation occurred just after the first tahrir and the case was forgotten and accepted as normal in time until the next tahrir, or such records were not taken for some other reasons.
Deforestation in Anatolia
Having analysed the Hüdavendigar sancak as far in detail as the the archival documents permit, it is also useful to dwell on other regions to show that deforestation was not limited to this area. When the documents of the period are investigated, it is seen that a great deal of deforestation data can be found also on many other regions of Anatolia, especially on the coastal regions which even today are intensely covered with forests. Among the studies conducted before, the first one that handled these records, including those on the 16th century, was M.A. Cook’s book entitled as “Population Pressure in Rural Anatolia”, which was published in 1972. As it is not the focus of his study, Cook deals with the subject of deforestation just in passing. However, to test his hypothesis of population pressure in Anatolia, Cook investigates the population rate to economic sources and the change of this rate in time in some districts, and he touches on the issue of deforestation in terms of the enlargement of agricultural areas to meet the needs of the increasing population. Relying on the proof he bases his idea on, he concludes that “population increase goes ahead of the increase in the sowed areas.” For calculating the population increase rate to the increase in cultivated areas between 1475-1575, Cook uses an index in which he determines the base point of this rate as 10 to 10 in 1475 and claims that this rate occurred as 12 to 17 in 1575. This means that while the population rate increased from 10 to 17, the area suitable for cultivating increased only from 10 to 12.[59]
The same situation was also valid for the Canik sancak in the north of Anatolia, which is studied by M. Öz only in terms of aquiring agricultural land. Certainly, the most important reason behind opening areas in forests is to aquire agricultural lands, but what is meant here is not the acquisition of agricultural lands but the consequence of the action taken, that is, the fact that agricultural lands are opened by damaging forests. In his study, M. Öz states that places of balta yeri (places for axe), that is, the places opened in forests in villages were mostly not recorded one by one with respectto their raiyyet names but as a whole, which proves that the extent of deforestation is more than recorded. In the archival documents, the records are given as follows: “mezbur karyenin hududu (dahilinde)nda reayası kuhiden açdıkları yerlerin mahsuliyle rüsumu (ve sonradan gelüb tavattun iden hariç reayanın rüsumu) karye-i mezbure hasılıyla mahsubdur (the tax of the things produced in the lands people opened out of forests in the borders of the mentioned village is recorded as a whole together with all the other taxes of the village)”. Cook underlines that in the last tahrirs the officials of the tahrir gave up recording the areas opened via deforestation in many places as reaya and preferred to record them together with others. However, in the Canik sancak such records in the last tahrir (1576) became less widespread when compared to that in 1554. As a matter of fact, the expressions of both balta yeri and kûhiden are used to refer to the same act. The first expression emphasizes clearing areas from trees and bushes, while the second one points to where the area takes place, that is, to the mountain. In the defter dated 1576 there are records of opening lands in forests/kûhi in 64 settlements of the Canik sancak. 2 of these records belong to Samsun, 19 to Kavak, 5 to Ünye, 12 to Satılmış, 15 to Arım, 8 to Bafra, and 3 to Terme. However, the total amount of deforestation should be noted to be more than that since these records were sometimes taken according to the person and sometimes as inclusive of the whole settlement.[60]
In his study,[61] A. Demir dwelled on the records of balta yeri and kilelik on the demand of the writers of this article and accessed the following record numbers on the issue in the last tahrir, that is, in the Tokat defter dated 1571. In the Tokat sancak, records of balta yeri and kilelik have been detected in 33 resedential areas of the district of Kilmigad and 19 areas of Kazabad, a total of 119 records being in the Kilmigad and 52 in Kazabad. These numbers indicate that the records of balta yeri that did not exist in the earlier tahrirs increased to a great extent towards the end of the century.
In the documents apart from the Tahrir defters, it is possible to have access only to indirect data on the issue. For instance, in a book[62] published by the Ministry of Forestry about forestry in the Ottoman period it is said that a petition sent in 1559 to the İznik kadi (Muslim judge) requested the obstruction of the cutting of trees for shipment from the forests on the mountains of Eşme, Dikme, and Sapanca (p. 3). Two petitions with similar content were sent in 1560 and 1565 to the Vize kadi and the sancak governor (p. 7 and 19). In another petition, dated 1565, there were requests concerning cutting trees for shipment from the mountains surrounding İznik (p. 17). Another one, which was sent in 1566 to the kadis of Hasköy/Khaskovo, Yanbolı/Yambol, Kırkkilise/Kırklareli, Ferecik/Ferea and Gümülcine/Komotini, requested not cutting trees from forests and using them for kışlak and ağıl (=temporary settlements established for stockbreeding) and not using forests for grazing livestock and hunting (p. 23). Two other petitions dated 1566 were also on the same issue (pp. 25-26). Together with the examples in the book under consideration, it is possible to find such records also in many other books,[63] and this shows the popularity of the subject in the period.
It is also necessary to mention here some of the indirect data on social groups and communities whose lives depended on forestry. ‘Tahtacılar’, lit. wood-cutters, took their name from their work and was one of the most outstanding communities of the period. This community, which continues to exist even at present, has been living throughout in the forests areas of the Mediterranean and Aegean regions and working in jobs related to trees and forests.[64] Apart from this group, communities named as Cemaat-i Baltacıyan and Cemaat-i Bedevreciyan, which directly lived on cutting trees and forestry. In the district of Sinop, the ‘baltacıyan community’ was recorded to exist in four villages and to consist in 1487, of 17 household (h) and 4 mücerred (m), in 1530, of 29 h, in 1560, of 28 h and 6 m, and in 1582, of 26 h and 16 m, all of whom lived on cutting trees from forests for ship and tower buildings when needed. Similarly, the ‘cemaat-i bedevreciyan (the community of bedevreciyan),’ which met the wood needs of these places, was recorded to include in 1487, 8 h and 6 m, in 1530, 9 h and 6 m, in 1560, nefer (a person of tax paying age) and in 1582 a total of 11 nefer. [65]
As understood from the documents, a great deal of the forests in the Ottoman lands faced deforestation due to the various reasons mentioned above. Keeping aside other reasons and taking into consideration only the deforestation made to meet the wood needs of the navy, it is seen in the documents that the wood needs of the navy were met particularly from the forests in the areas closely surrounding of İstanbul. However, since this process began in the Byzantian period, the forests in the area closely surrounding İstanbul were supposedly already quite damaged in the middle of the 16th century. İ. Bostan, who works in the navy, affirms this information and states that the wood used for ship building in the İstanbul Haliç Navy Yard was mostly supplied from the area surrounding İstanbul.[66] The fact that the Byzantians had navy yards in such centers as İstanbul and İzmit before the Ottomans shows the existence of forests suitable for shipment in the region. Besides those mentioned above, the existence of such navy yards in the 16th century close to this region suchas Sapanca, Şile, Kefken, and those a bit farther such as Gelibolu, Silivri, Akçaşehir, Alaplı, Ereğli[67] is completely related to the forests in the region. When others are kept aside and only the acts of the navy yards in İstanbul are taken into consideration, it is observed that from 1527 to 1585 a total of 83 ships were built while 260 ships were maintained and repaired. When the same issue is investigated for the following years, the pressure on the forests in the region is seen to have increased instead of decreased. In the İstanbul navy yard from 1610 to 1701 a total of 317 ships were built and 808 ships were maintained and repaired. In the same study, it is possible to observe the increasing pressure on forests also by taking into consideration the fact that the forests used for shipment were accumulated over the areas in the eastern and southern parts of the Marmara Sea.[68]
As said above, when the documents are investigated, it is seen that until the mid 16th century the trees needed for shipment had either decreased or almost totally disappeared, and this indicates that trees from placesa bit farther away began to be requested for naval purposes. It is possible to confirm this fact from the documents published in the book mentioned above[69]: For instance, in a document dated 1559, there is a petition sent to the governor of Rhodes which stated the demand for trees suitable for shipment and requested the search for whether such trees were present in Rhodes and its surrounding areas (p. 5). In another document dated 1571, wood needed for naval purposes was requested from the Sinop kadi (p. 5).
Apart from these data that directly prove deforestation, we can also touch upon the efforts for changing the tree types in the forest cover. Actually, in an Ottoman lawbook (kanunname) dated H. 971/M. 1563, such records as
“dağlarda ve ormanlarda yetişen hudayi nabit ağaçları birisi sipahiden müsaade alarak aşılasa onlar aşılayanın mülkü olur, meyvesini o kimse toplayarak yalnız öşrünü sipahisine verir. Dağda ve ormanda yetişmiş hudayi nabit meyve ağaçları ki bunlar aşılanmamıştır, bunları yemişi ile sahipsiz arazilerde yetişen ota kim sahip çıkar toplar ve biçerse onun olur, bundan öşür alınmaz, ancak iyi muhafaza edilmesi şarttır (If by getting permission from the cavalryman/sipahi a person inoculates, looks after and reaps trees that grow by themselves on mountains or in forests, these trees become his own; however, he should pay their tax to the cavalryman (sipahi). The non-inoculated trees and grass that grow in nature are also subject to the same application; if a person reaps the trees and looks after the grass and saws it, he does not pay tax for the product, but he should take care of the trees and the grass and get the product without giving harm to the trees)” [70]
indicates that the tree types in the forest cover were changed. The presence of such articles in the kanunnames, though they are not direct expressions of deforestation, can be seen as facilitating deforestation by promoting the change of tree types in the forest cover. In the studies conducted on the issue, it is demonstrated that the tree types in the forest cover of Anatolia were changed due to the grazing of animals that lasted for thousands of years, and, among these studies, a study conducted by Hütteroth states that the wide forests of pine trees existing in Anatolia were changed into forests of oak trees after being destroyed.[71]
Conclusion
As can be seen, from the discussion so far, because of its geographical position and historical characteristics, Anatolia has been one of the main areas in the world subjected by humankind to deforestation from the beginning of its history. This process, which began with the invention of fire, has continued until the present and has been gradually speeding up with forest fires, acts of mining, and opening agriculture and grazing lands, settlements, and roads, all of which show the ominous effect of human intervention. While the deforestation before the Ottoman period was detected as far as recorded in historical data, which were most of the time indirect and touched upon the issue just in passing, it is possible via the Ottoman archives to have access to direct and indirect data on the deforestation in the Ottoman period that present much more definite information on where, with what purposes and to what extent deforestation occurred in this period.
Primarily from the tahrir defters and from such other documents as mühimme defters, kanunnames, and şeriyye sicils it is understood that the forests in the coastal regions of Anatolia were exposed to deforestation throughout the Ottoman period. The forests along the coasts of the Black Sea, Marmara Sea, Aegean Sea and Medirranean Sea, especially those around the capital city İstanbul with its huge population, always faced deforestation for ship building and minery, and for providing the increasing population with agriculture and grazing lands, settlements, heating facilities, equipment, and energy. This deforestation culminated particularly in the 16th century simultaneously with the rapid increase of population; forests were damaged in this century to meet the growing needs of the population and for the sake of opening new agricultural and grazing lands and establishing settlements. Certainly, though not much recorded in the archival documents, the forest fires that have taken place throughout the history of Anatolia -from the early times until the present- which still cannot be prevented, make the issue of deforestation more tragic.
The forests in the inner parts of Anatolia became in time anthropogenic steps after being destroyed because the geographical and climactic conditions were not appropriate for their revonation. In the coastal areas, on the other hand, depending on the appropriate climactic conditions, the forests that were destroyed could renovate themselves in a short while and thus in these areas the process of deforestation depended on the extent of destruction done by people. Since it was on the coast of the Marmara Sea, which had a rich forest cover that could renovate itself, the Hüdavendigar sancak faced deforestation from its early times onwards. In addition, its closeness to Bursa as well as to İstanbul, which were the greatest cities of the time, played an important and accelerating role in the deforestation. Among other reasons, the fast increase of the population in the sancak (as well as all over Anatolia) in the 16th century played a detrimental effect on forests, as more and more agricultural and grazing lands were opened to meet the growing needs of the population. As far as can be understood from the documents, in this process, from the mid 16th century to the end of the century, forests and other vegetation cover an area of approximately 323,7 ha, that is, 650-700 ha were destroyed and opened to agriculture. Particularly, deforestation was on a high level in areas situated in the southern and eastern parts of the sancak such as Taraklu, Beypazarı, Akyazı and İnegöl where there was a rich forest cover, whereas in other places less deforestation records exist. According to the calculations done here, the areawhich underwent deforestation in the sancak seems at first glance to be small when calculated in terms of the areameter of the sancak; however, the issue becomes much more important when one takes into consideration that the deforestation involved occurred in a 52-year period of time, which is rather short, the forests destroyed could not renovate themselves and that this process accelerated in the following periods.
We have also observed that deforestation occurred in the 16th century even in such a narrow area as Hüdavendigar sancak, which suggests the extent of deforestation which took place in Anatolia as a whole in this period. As it is in other regions of the world, the process of deforestation is known to have continued in Anatolia after the century under consideration.[72] Furthermore, it has doubtlessly accelerated in parallel to population increase and growing population needs. For whatever purpose and in whatever way it is done, deforestation is an important issue and has become today a means of ecological change that should be prevented. As a matter of fact, though it has occurred throughout history, its danger for humanity and the ecology has been realized only in the last century. The subject of deforestation that has always been important in the history of Anatolia is today a much more crucial problem. Though this is true for the entire world, unfortunately studies on its process and solutions are conducted almost only in western countries. This study, which may be a small contribution to these studies, is in a way an introduction to the investigation of deforestation in Anatolia. Certainly, this short introduction is not enough and for a more comprehensive view of the matter in Turkey further studies should be conducted and in spatial terms a larger area should be explored.
