Democracy and deforestation. The politics of protecting the forests

Décembre, 2001
Philippines
Asie orientale
Océanie

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.

Micro-level analysis of farmers' adaptation to climate change in Southern Africa

Afrique sub-saharienne

Adaptation to climate change involves changes in agricultural management practices in response to changes in climate conditions. It often involves a combination of various individual responses at the farm-level and assumes that farmers have access to alternative practices and technologies available in the region.

The Economic Valuation of Tropical Forest Land Use Options: A Manual for Researchers

Décembre, 1997

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.

Impact of fertilizer use on weed management in conservation agriculture - a review

Décembre, 2013

Intensive farming has been adopted to produce large amounts of food grains and cash crops but environment is being deteriorated at alarming rate also. Increased use of fertilizers, pesticides, chemical growth regulators, machinery and poor management practices are accelerating environmental pollution, soil degradation, global warming, climatic change and food deterioration. Conservation agriculture offers a sustainable solution for all these problems most often. This review focuses the use of fertilizers in conservation agriculture and their impact on weed management.

Climate variability and maize yield in South Africa: results from GME and MELE methods

Décembre, 2008
Afrique du Sud

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.

The land-use sector within the post-2020 climate regime

Août, 2014

This report analyses the current status of the land-use sector under the United Nations Framework Convention on Climate Change and its Kyoto Protocol, and formulates options for how various incentives and systems could be harmonised under a future climate treaty. It argues that the land-use sector serves key environmental and social functions and supports the livelihoods of around a half of the world’s population. However, it is argued that the climate regime fails to formulate a coherent vision or set of incentives for mitigation and adaptation from the sector.
