A University of Leeds collaborative study has probed links between environmental change and famine – two problems perceived to lie at the heart of Africa’s current crisis – in the context of another all too often linked to the continent - warfare and civil unrest. Land hunger and environmental depletion in the aftermath of war are often cited as causes of famine that in turn will lead to further conflict. Is such a chain reaction really at work? Is there an inevitable causal link between environmental degradation and violent conflict?

How can the process of tropical deforestation be controlled? We now know a good deal about the causes of deforestation but not its control. Research from the University of Leeds in Thailand and the Philippines fills this gap, showing that changes in the domestic political scene explain how deforestation processes have been controlled in the two countries. Environmental constraints and increases in agricultural productivity can curb the demand for farmland to some extent.

This paper considers the degree of environmental variability in an extensive pastoral area of Altay, northern Xinjiang (China); assesses the extent to which institutional arrangements are able to accommodate environmental variability, and discusses the implications of this for rangeland policy.The article finds that:there is some inter-temporal variation in rangeland productivity (in pasture zones), suggesting some applicability of new range ecologythere is less environmntal variation in summer pasture, suggesting that the concepts and tools of conventional rangeland management might be mor

This paper examines the evidence for land degradation in Burkina Faso, and argues that local farming practices are not as unsustainable and environmentally destructive as many reports suggest.Main findings of the study include:there is little evidence of widespread degradation of crop and fallow land in Burkina Faso; the low external input practices used by West African farmers are not leading to region wide land degradation processesa major reason for the overestimation of land degradation has been the underestimation of the abilities of local farmersthere is much more to soil and water co

The 21st Century opened with a commitment to involving forest-local communities in the processes of securing and sustaining forests. But what is the relationship between people’s right to land and the manner in which they may be involved in the management of forests?

This document presents the results of an evaluation of an IFAD project aimed at preventing land degradation in Nepal. The project is based on leasehold forestry, an innovative approach introduced by IFAD in the early 1990s. It works by providing forty-year leases to groups of households and giving them user rights over plots of degraded forest land.

Manual for researchers in Southeast Asia involved in the economic evaluation of tropical forest land use options. It was developed initially to serve as an aid to Cambodian researchers in the execution of an EEPSEA-financed study of non-timber forest values in Ratanakiri Province, Cambodia. The aim of the manual is to provide non-specialists with a basic theoretical background to economic valuation of the environment and with a practical methodology for an economic evaluation of alternative tropical forest land uses.

This paper investigates the impact of climate variability on maize yield in the Limpopo Basin of South Africa using the Generalized Maximum Entropy (GME) estimator and Maximum Entropy Leuven Estimator (MELE). Maize constitutes about 70 percent of grain production and covers about 60 percent of the cropping area in South Africa. It is a summer crop, mostly grown in semiarid regions of the country, and is highly susceptible to changes in precipitation and temperature.

Climate models are predicting a hotter, drier and less predictable climate in the Middle East, a region already considered the world's most water-scarce and where, in many places, demand for water already outstrips supply. This report addresses the links between climate change, peace and conflict.

This report aims to improve the knowledge base for scaling-up investments in land management technologies that sequester soil carbon for increased productivity under changing climate conditions. The report presents the following key messages.

In this paper, the results of a recent case study of forest conservation and management in Sariska Tiger Reserve, Rajasthan, India are reported. Changes in land use, grazing, household fuelwood collection and inadequate management institutions are identified as key factors causing forest degradation. The paper demonstrates that quantitative analysis, employing data from fairly large samples of households and villages, is a useful supplement to the qualitative methods dominating in studies of conservation and natural resource management institutions.

This paper assesses the underlying causes of deforestation and forest degradation and the forces behind unsustainable agriculture. It demonstrates the far-reaching consequences of globalisation, in terms of land tenure policies and inequalities. It examines consumption and production patterns and the global problem with many actors.
