The relationship between livestock production and climate change is the subject of hot debate, with arguments for major shifts in diets and a reduction in livestockproduction. This Perspective examines how global assessments of livestock-derived methane emissions are framed, identifying assumptions and data gaps that influence standard life-cycle analysis approaches.
The growing number of farmer-herder resource conflicts in Tanzania is often presented in official narratives as a product of climate change resulting from increased environmental pressures. Nonetheless, based on a qualitative research, this paper asserts that farmer- herder conflicts in Rufiji and Kisarawe districts should be understood in terms of the marginalization of pastoral community interests over access to land. This has created what Hall, Hirsch and Li [2013. Power of Exclusions: Lland Dilemmas in Southeast Asia.
This paper examines the roles of the state, international organisations and the public in pastoral land reform in the Central Asian republics and Mongolia. In recent years new legislation has been passed in most of these countries, often driven by environmental concerns. In the development of these laws, international organisations tend to promote common property regimes, whilst governments usually emphasise individual security of tenure, each using environmental arguments taken from quite different bodies of theory.
This paper looks at how recent economic and legal changes have affected pasture management and property rights in Tajikistan. Firstly, current trends in livestock numbers and mobility are compared with those of the Soviet period. Secondly, the impact of current land legislation is investigated using 2007 field data from two sites in the Gorno-Badakhshan region of the country. We describe the extent to which pasture at these sites is under private, community or state control and discuss the implications for sustainable management of this resource.
This article uses data from household income surveys to look at income structures amongst households in three mountainous regions of Tajikistan: Gorno-Badakhshan, the Rasht Valley and Eastern Khatlon. The structure of incomes demonstrates the dominant role of subsistence agriculture in all three regions although commercial agriculture is important amongst better-off households in Rasht. Relationships between poverty and household characteristics including access to capital, demographic variables and income-generating activities were examined.
This paper examines the impact of land reform on agricultural productivity in Tajikistan. Recent legislation allows farmers to obtain access to heritable land shares for private use, but reform has been geographically uneven. The break-up of state farms has occurred in some areas where agriculture has little to offer but, where high value crops are grown, land reform has hardly begun. In cases where collectivized farming persists and land has not been distributed, productivity remains low and individual households benefit little from farming.
Climate warming and human actions both have negative impacts on the land cover of Mongolia, and are accelerating land degradation. Anthropogenic factors which intensify the land degradation process include mining, road erosion, overgrazing, agriculture soil erosion, and soil pollution, which all have direct impacts on the environment. In 2009–2010, eroded mining land in Mongolia increased by 3,984.46 ha., with an expansion in surrounding road erosion. By rough estimation, transportation eroded 1.5 million ha. of land.
This paper analyzes frontier dynamics of land dispossessions in Ethiopia’s pastoral lowland regions. Through a case study of two sedentarization schemes in South Omo Valley, we illustrate how politics of coercive sedentarization are legitimated in the ‘civilizing’ impetus of ‘improvement schemes’ for ‘backward’ pastoralists. We study sedentarization schemes that are implemented to evict pastoralist communities from grazing land to be appropriated by corporate investors.
Representation of land-use and hydrologic interactions in respective models has traditionally been problematic. The use of static land-use in most hydrologic models or that of the use of simple hydrologic proxies in land-use change models call for more integrated approaches. The objective of this study is to assess whether dynamic feedback between land-use change and hydrology can (1) improve model performances, and/or (2) produce a more realistic quantification of ecosystem services. To test this, we coupled a land-use change model and a hydrologic mode.
