The intensification of production: Archaeological approaches

In this paper I reexamine the Boserup model of agricultural intensification and archaeological reaction to it. Although causes have been extensively debated, little attention has been paid to process, and even those who reject the causal efficacy of population may adopt other aspects of the Boserup model. These unexamined aspects include the assumption that intensification proceeds along a single course, characterized by gradual decreases in the frequency of cropping. I suggest that the course of intensification is complex and variable and that, only by breaking down the process of intensification into its component strategies, can we come to an understanding of both the causes and the courses of intensification.     

BOSERUP BACKWARDS? AGRICULTURAL INTENSIFICATION AS ‘ITS OWN DRIVING FORCE’ IN THE MBULU HIGHLANDS,TANZANIA

Why do farmers intensify their agricultural practices? Recent revisions of African environmental historiographies have greatly enriched our understanding of human–environmental interactions. To simply point at poor farming practices as the main cause of deforestation, desertification and other processes of land degradation is, for example, no longer possible. The contemporary analytical focus is instead on the complex and often unpredictable set of causal relations between societal, ecological and climatic factors. In the literature on agricultural intensification, conventionally defined driving forces, such as population pressure and market demand, remain important explanatory factors despite a growing body of research that suggests more dynamic scenarios of agricultural development and landscape change. This article reports on a case where the common‐sense logic of population pressure theory has dominated the historical narrative of a local process of agricultural intensification among an agro‐pastoral people in north‐central Tanzania. By way of a ‘detailed participatory landscape analyses’ a more complex and dynamic historical process of intensification is suggested, in which the landscape and the process of agricultural intensification itself are in focus. It is concluded that the accumulation of landesque capital has been incremental in character, and that the process of agricultural intensification in the study area has largely been its own driving force based on self‐reinforcing processes of change, and not a consequence of land scarcity and population pressure. This result demonstrates the possibility and usefulness of reversing the Bose‐rupian argument in analyses of agricultural intensification.     

Population Density,Economic Growth and Societies in Transition: Boserup Reconsidered in a Kenyan Case-study

In examining the relationship between population growth and income growth, this article first looks at the Malthusian, transition and revisionist positions. The first is not borne out by historical experience, and the latter two do not explain why greater affluence generally leads to lower rates of population growth. It is argued here that the crucial population characteristic is density. Rising densities from a low base facilitate more productive agriculture and greater specialization and exchange within a society, as Boserup (1965) pointed out. This leads to increased wealth but also to higher costs for education and land. This provides a link to Caldwell's (1976) explanation of changing attitudes to family size: at low densities in simple societies benefits from children exceed costs, while at higher densities in complex societies costs exceed benefits. The changes in societies and economies are illustrated by a Kenyan case study. Kenya has experienced particularly rapid population growth this century, and high economic growth; it is now experiencing the transition to lower birth rates.     

延安市农民收入可持续增长机制探析

近年来,延安市农民人均纯收入一直低于全国平均水平,城乡居民收入差距也不断扩大。为改变这一局面,延安市政府实施了生态移民工程,进行了农业产业结构调整。这些措施在一定程度上改善了农民的生活水平,但是,制约农民收入增长的根本性障碍仍然存在。只有促进高附加值农业的可持续发展、鼓励农村剩余劳动力的外出就业和使农村非农产业实现较快发展,才能建立起农民收入的可持续增长机制。     

Emprise et déprise de l'agriculture sur le territoire de l'est de l'Ontario de 1826 à 2006: la dimension environnementale

Agricultural land‐cover changes in Eastern Ontario from 1826 to 2006: environmental effects. Stormont, Dundas and Glengarry (SDG) counties, Eastern Ontario, are among the first areas in Ontario to welcome settlers. In 1784, they established themselves in a forested land where wetlands are very important. Today, a large part of the wetlands has disappeared, but the landscape is wooded, masking the radical changes that took place over the course of the last two centuries. Analysis of census data from 1826 to 2006 allows the reconstruction of the history of land‐cover changes. It reveals the nature and rates of change for which a first analysis is presented. Four periods are identified. First, agriculture conquers the land and establishes its dominance. A plateau is reached in 1891 as agriculture maintains its supremacy until 1941. Then, as fast as agriculture invaded land, it fades away until 1986 when agricultural land‐cover stops shrinking. The opening of forest for cultivation was relatively slow in SDG because of biophysical and socio‐economical conditions associated with an absence of growth of agricultural population. Deforestation and wetland drainage led to a degradation of agricultural life but resulted in consideration of the environment in agriculture. Today, wooded and agricultural land covers are more balanced and environmental effects less acute.     

Consuming the forest in an environment of crisis: nature tourism, forest conservation and neoliberal agriculture in south India

This article engages ethnographically with the neoliberalization of nature in the spheres of tourism, conservation and agriculture. Drawing on a case study of Wayanad district, Kerala, the article explores a number of themes. First, it shows how a boom in domestic nature tourism is currently transforming Wayanad into a landscape for tourist consumption. Second, it examines how tourism in Wayanad articulates with projects of neoliberalizing forest and wildlife conservation and with their contestations by subaltern groups. Third, it argues that the contemporary commodification of nature in tourism and conservation is intimately related to earlier processes of commodifying nature in agrarian capitalism. Since independence, forest land has been violently appropriated for intensive cash-cropping. Capitalist agrarian change has transformed land into a (fictitious) commodity and produced a fragile and contested frontier of agriculture and wildlife. When agrarian capitalism reached its ecological limits and entered a crisis of accumulation, farming became increasingly speculative, exploring new modes of accumulation in out-of-state ginger cultivation. In this scenario nature and wildlife tourism emerges as a new prospect for accumulation in a post-agrarian economy. The neoliberalization of nature in Wayanad, the authors argue, is a process driven less by new modes of regulation than by the agrarian crisis and new modes of speculative farming.     

清嘉道以来伯都讷围场土地资源再分配

位于吉林的伯都讷围场,在清代围场中放垦最早,也是嘉道以来清廷对所控有的围场封禁土地资源进行的第一次招民而非旗丁的开垦,是在人口增加、农耕土地资源紧缺情形下,国家不得不对所控制的土地资源重新调整、加以分配的一个特例。整个过程中,不仅显现出农耕土地资源私有化的局面,也涉及官民双方在资源分配中的利害关系。清代中国的人与自然环境系统中,对资源环境的调控是在国家权力支配下完成的,国家权力和政策是这一环境系统发生改变的主要动力。     

Poverty and Agrarian‐Forest Interactions in Thailand

In this paper we address the often sterile and circular debates over relationships between poverty and deforestation. These debates revolve around questions of whether forest loss causes poverty or poverty contributes to forest encroachment, and questions of whether it is loss of access to forests or dependence on forest‐based livelihoods that cause poverty. We suggest that a way beyond the impasse is to set such debates within the context of agrarian change. Livelihoods of those who live in or near forests depend considerably on a rapidly changing agriculture, yet agrarian contexts receive only background attention in popular, political and academic discourse over poverty and forests. Moreover, to the extent that agriculture is considered, little heed is paid to social, technical and economic change. We therefore address agriculture's changing relationships with the wider economy, otherwise referred to as the agrarian transition, and with the natural resource base on which it depends. The paper draws on the experience of Thailand to illustrate our key argument, and more specifically addresses the situation on the resource periphery through a look at the agriculture‐forest interface.     

传统平原农区人口非农化对耕地利用方式的影响

传统平原农区是我国重要的粮食产区和人口集聚区,也将是我国未来人口城镇化的快速发展区。本文基于农村劳动力就业转移与农户家庭总收入之间的数量关系,提出农区发展演化三阶段的理论,并选取不同发展阶段的河南省吴庄村和山东省东店村进行验证。结果表明:微观层面的人口非农化特征与农户家庭总收入存在相关性,宏观层面的县域经济发展能力是农户兼业行为特征的重要外因;兼业农户通过土地流转,种植结构调整改变传统耕作方式,优化了农业与非农业收入结构,并推动农区进一步的发展演变。通过分析传统平原农区人口非农化对耕地利用方式的影响机理,对于保障粮食安全、推进该类型区的社会经济转型具有一定的现实意义。     

Developing a Synthetic Index of Land Vulnerability to Drought and Desertification

This paper develops an index of the vulnerability of land to drought and desertification (LVI) for Italy. The index takes into account changes in climate, land use, vegetation cover, soil properties, and population during the period 1990–2000. The LVI was built up through a multivariate approach aimed at assessing the importance of the various indicators included in the synthetic index. Increasing land vulnerability was observed during this time, especially in dry areas of the southern regions. This is interpreted as a consequence of land management practices, agricultural intensification, population pressure, and bio-physical degradation. The LVI can be used in an integrated, decision-support system to evaluate the impact of mitigation policies in rural environments.     

The Broad Spectrum Revolution at 40: Resource diversity,intensification, and an alternative to optimal foraging explanations

More than 40 years ago Kent Flannery coined the term Broad Spectrum Revolution (BSR) in reference to a broadening of the subsistence base of Late Pleistocene hunter–gatherers in the Near East that preceded and helped pave the way for the domestication and plants and animals and the emergence of agriculture. Set within a demographic density model that projected differential rates of population growth and emigration in different resource zones of the Near East, Flannery’s BSR quickly became a global construct linking resource diversification and intensification to imbalances between population and environmental carrying capacity. In recent years the BSR has proven especially attractive to researchers working within an optimal foraging theory (OFT) framework in which diversification and intensification of subsistence only occurs within the context of resource depression, caused by either demographic pressure or environmental deterioration. This OFT perspective, that situates human societies in a one-way adaptive framework as they are forced to adapt to declining availability of optimal resources, however, is increasingly being called into question. Numerous examples of diversification and intensification are being documented in contexts of resource abundance shaped, in part, by deliberate human efforts at ecosystem engineering intended to promote resource productivity. An alternative approach, framed within a newer paradigm from evolutionary biology, niche construction theory (NCT), provides a more powerful explanatory framework for the BSR wherever it occurred.     

Microfossil evidence of land-use intensification in north Thailand

Palaeo-environmental data from accumulated lake sediments at Phayao, northwest Thailand, provide a record of vegetation and environmental change from approximately 20,000 years Before Present. This is an important region archaeologically, with claims in the 1970s for an ‘early’ transition to domestication having arisen from a number of cave sites. Multiple indices are used to determine if people had an observable impact on the natural environment, and to determine the timing and magnitude of impacts associated with the development of agricultural land use in the region. An initial increase in sedimentation rate is apparent from ca. mid-2nd C AD. Changes in phytoplankton concentrations are apparent from the late 3rd C AD, and evidence for initial forest disturbance is apparent from the 5th or 6th C AD, with impacts becoming more severe over time to reach a pre-modern maximum in the 11th to the 13th C AD. Changes in agricultural practices are apparent during the 14th C AD, with an increased emphasis on rice agriculture and incipient management of the regenerating forests. Based on these data we suggest that agricultural intensification in the early part of the 1st millennium AD destabilised catchment slopes, through clearance of dryland vegetation and swidden agriculture. There is no direct evidence for the impacts of earlier peoples on the vegetation of the area, which we take to indicate that agricultural intensification was later here than in the lowlands to the east and south.     

Peasant Women and Economic Transformation in The Gambia

Contemporary agricultural development strategies in The Gambia are centred on irrigated rice and vegetables—crops traditionally cultivated by women. Irrigated agriculture, however, is opening up new avenues to capital accumulation at the national, regional and household levels. This article examines the contradictions for women of donor-funded schemes that combine gender equity with productivity objectives. The gender conflicts rife in Gambian irrigation projects point to the significance of female labour for contemporary patterns of agrarian transformation as well as the linkage between women's access to land for independent farming and forms of project participation.     

汉代中国经济、社会和国家权力--评许倬云的《汉代农业:早期中国农业经济的形成》

许倬云所看的《汉代农业：早期中国农业经济的形成》是美国西雅图华盛顿大学”汉代研究丛书”之一种。该著作不仅为西方读者考察和介绍了关于汉代农业的重要史料,而且还进一步诠释了古代中国农业经济、社会和国家发展的历史。但是,受魏特夫“亚细亚型社会”和“东方专制主义”观点的影响,作者在运用相关考察汉代农业经济时,却忽略了对传统史料的考证和诠释。这种倾向,导致了作者在论述水利工程、人口增长、佃农人数、国家权力和田租数量等影响农业经济发展的要素时,忽略或误读了传统史料所表达的基本信息。同样,作者对汉代地主阶级势力所作出的过低的估计也存在着相当问题。实际上,整个汉代,地主阶级的发展是极为活跃的：西汉后期,地主豪强兼并土地已愈演愈烈;迨至东汉,随着田庄的兴起,汉朝统一的根基不断被腐蚀,最后终于瓦解了汉王朝的统治。     

Sowing the Seeds of Modernity on the Ottoman Frontier: Agricultural Investment and the Formation of Large Farms in Nineteenth-Century Transjordan

In the nineteenth century, the Ottoman Empire initiated a series of modernization reforms. In an effort to address the economic viability of the state, it turned its attentions to its frontiers, in an attempt to bring these regions back into the fold of the empire. In Transjordan, the state targeted Bedouin subjects; as part of the Ottoman project of modernity, efforts were made to settle nomadic pastoralists and transform pastureland into agricultural spaces. The rural countryside was opened to capitalist investment in agriculture. However, agricultural intensification, and the establishment of large farms created a crisis of modernity for many Bedouin. The intensification of agriculture brought increased taxation, diminished control over production, indebtedness, and ultimately the appropriation of land. But some Bedouin used the built environment and natural landscape to confront the Ottoman project of modernity as it unfolded on the frontier.

Agricultural Development and Household Incomes in Central Asia: A Survey of Tajikistan, 2003-2008

Two noted specialists on the agricultural economies of the former Soviet Union examine the effects of land reform on agricultural production and the income of rural house-holds in Tajikistan. The authors utilize official government statistics to discern trends of agricultural output at the national level, and the results of three extensive surveys conducted in 2007-2008 (N > 2,000) and one in 2003 (N = 4,000 respondents) by international organizations (United Nations Food and Agriculture Organization, Asian Development Bank, the U.S. Agency for International Development, World Bank) to identify household-level changes. They also review the legislative framework for agrarian reform in the country; examine national-level trends in farm structure and organization, livestock production, farm productivity, and cropping patterns; and analyze shifts in size of land holdings and rural family incomes at the household level.

Relational Economies,Social Embeddedness and Valuing Labour in Agrarian Change: An Example from the Developing World

A relatively neglected area of research on agrarian and economic change is the role of indigenous concepts of labour value in the transition from subsistence to market production. In West New Britain Province, Papua New Guinea, the presence of a migrant population on an oil palm land settlement scheme (LSS) in close proximity to village‐based oil palm growers, provided an opportunity to examine changing notions of labour value through the lens of smallholder productivity. Voluntary settlers on the LSS are experiencing population pressure and are highly dependent on oil palm for their livelihoods. In contrast, customary landowners in village settings produce oil palm in a situation of relative land abundance. By examining differences in how these two groups practise and value commodity production, the paper makes four key points. First, concepts of labour value are not static and involve struggles over how labour value is defined. Second, the transition to market‐based notions of labour value can undermine labour's social value with a consequent weakening of social relationships within and between families. Third, Theories of Value developed in western contexts and used to frame development policies and projects in the developing world are often inappropriate and even harmful to the welfare of communities that have different registers of value. Fourth, in response to Point 3, and following Rigg (2007), there is a need for ‘theorising upwards’ using empirical data from the developing world to inform theory rather than applying to the developing world models of sociality and economy developed in western contexts.     

'They Never Trusted Me to Drive': Farm girls and the gender relations of agricultural information transfer

This research explores the ways in which the gender relations of family farming influence the transfer of agricultural information and knowledge resources to farm girls, a rarely studied population. The study is based on a sample of 32 female farmers from southern Ontario, who were interviewed extensively about their experiences growing up on family farms, and about their lives as adult farmers. Their accounts underscore the fact that the gendered division of labour evident on North American farms constrains the information passed on to farm girls (and women) in particular ways. Farm girls do not share fully in the occupational inheritance of agriculture - they are frequently excluded or marginalised from important agricultural resources, including information. This exclusion comes about through the ongoing social processes of agrarian patriarchal culture, operating both inside and outside of the agri-family unit. In particular, the study illustrates how the social construction of agriculture is heavily reinforced by certain types of myth-making, which work to disadvantage farm girls and women.     

Declining Food Security in a Philippine Oil Palm Frontier: The Changing Role of Cooperatives

The long‐held redistributive function of agricultural cooperatives — one of moral economy and poverty alleviation — has changed dramatically as they emerge as core brokers for agro‐industrial development in the so‐called ‘green economy’. This article examines the changing role of cooperatives involved in brokering oil palm production and its impact upon the food security and livelihoods of smallholders who labour in plantation regimes situated in historically uneven agrarian political economies. Findings show how, increasingly, cooperatives reinforce uneven agrarian social relations of production and exchange in which indigenous smallholders experience loss of land, poor wage labour conditions tinged with insecurity and prejudice, and mounting debt in an expanding oil palm complex. The article suggests that these changes in agrarian social relations negatively influence indigenous farmers’ food security pathways, with their access to and use of appropriate foods diminishing. It asserts that understanding the impacts of cooperatives on food security pathways requires a relational and situated analysis of livelihood change and agrarian relations in extractive frontiers.
