Better Land Husbandry: Re-thinking approaches to land improvement and the conservation of water and soil

Diciembre, 1996

Soil erosion has conventionally been perceived as the chief cause of land degradation, yet the limited effectiveness and poor uptake of widely promoted physical and biological anti-erosion methods challenges this logic. An alternative perception focusing on prior land damage - notably to soil cover, architecture and fertility - permits an holistic, farmer-centred approach which has generated positive response to date.

Africa: atlas of our changing environment

Diciembre, 2007
África subsahariana

This African atlas is the first publication to use satellite photos to depict environmental change in each and every African country during the last thirty years. Through an array of satellite images, graphs, maps, and photographs, this Atlas presents a powerful testament to the adverse changes taking place on the African landscape as a result of intensified  natural and human impacts. The atlas is composed of three parts:

Roads, population pressures and deforestation in Thailand, 1976 - 1989

Diciembre, 1996
Tailandia
Asia oriental
Oceanía

Population pressures play less of a role in deforestation than earlier studies of Thailand found. Between 1976 and 1989, Thailand lost 28 percent ofits forest cover. To analyze how road building, population pressure,and geophysical factors affected deforestation in Thailand during that period, Cropper, Griffiths, and Mani develop a model in whichthe amount of land cleared, the number of agricultural households,and the size of the road network are jointly determined.The model assumes that the amount of land cleared reflects an equilibrium in the land market.

Best practices of Environmental Information Systems (EIS): the case of Zimbabwe

Diciembre, 1996
África subsahariana

report considers the potential, constraints, successes and weaknesses of EIS (environment and land information systems, geographical information systems (GIS)), based on practical approaches in Zimbabwe were assessed and lessons-learnt were developed.The process of developing a national EIS in Zimbabwe is also in the evolutionary phase. The country does not yet have a comprehensive nationally co-ordinated EIS. At the time of this study, several information systems co-exist which can be considered EIS sub-systems.

Tragedy of the Commons for Community-based Forest Management in Latin America?

Diciembre, 1996
América Latina y el Caribe

This paper considers the evidence surrounding the popular view that common property management regimes (CPMRs) of forest management in Latin America must inevitably break down in the face of economic and demographic pressures. The evidence shows that there have been both positive and negative experiences, with a number of policy implications. The over-riding need is to correct for institutional and policy failures which have catalysed the erosion of CPMRs.

New Institutional Economics: A Survey of Property Rights and Natural Resource Management [case study from Rajasthan]

Diciembre, 1997

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.

Fuelwood Consumption and Forest Degradation: A Household Model for Domestic Energy Substitution in Rural India [Rajasthan]

Diciembre, 1997

Paper examines domestic energy supply and demand in Northwest India. A household model is set up to analyse the links between forest scarcity and household energy consumption, focusing on the substitution of fuels from the forests and commons and the private domain. The model is estimated using recently collected data from villages bordering Sariska Tiger Reserve in Rajasthan, India. A novel maximum entropy approach is used for estimation.
