Mesoamerican coffee: building a climate change adaptation strategy

Janvier, 2013
Mexique
Amérique latine et Caraïbes

In Mesoamerica, coffee is an important part of agricultural GDP and export revenues which supports about half a million farmers, and employs millions of people on the farms and all along the supply chain. This policy brief summarises the potential risks and impacts of climate change on coffee farming in the region. Traditional coffee agroforests provide important ecosystem services and conserve significant carbon stocks.

Spotlight on publications: extractive industries and land use

Décembre, 2011
Amérique latine et Caraïbes

Questions about land use are inextricably related to decisions about where and how to engage in extractive industry activities. Latin American countries have dealt with a range of land-related challenges, from land use planning and consent for securing access to land, to special considerations for indigenous peoples and environmental conservation, all of which have important implications for governments and local communities. This selection highlights some of the key publications dealing with issues of extractive industries and land use in Latin America

What is a REDD+ Pilot?

Asie méridionale

This policy brief, published by the Centre for International Forestry Research, provides a snapshot of 17 REDD+ pilot projects in Indonesia. It begins by discussing early REDD+ pilots in Indonesia and then provides a comprehensive typology of REDD+ activities in Indonesia. The brief continues with a discussion of the motivation behind different pilot models and the following section outlines research needs and implications of REDD+ design in Indonesia.

The new competition for land: Food, energy, and climate change

Décembre, 2010
États-Unis d'Amérique
Brésil
Europe

This paper discusses the competition for land resources and the issue of land-use change due to the rising demand for food and energy, specifically for the transport sector. The linkages between land, food, and energy become particularly complex within the context of climate change. This is not only because agriculture contributes to greenhouse gas emissions, but also because climate change itself can alter the productivity and availability of land.

Promoting food security in Rwanda through sustainable agricultural productivity : meeting the challenges of population pressure, land degradation, and poverty / Daniel C. Clay ... [et al.]

Décembre, 1995
Rwanda
Afrique sub-saharienne

The objective of this technical paper is to shed insights on ways of reversing the spiraling decline of the land and the economy in rural Rwanda, with focus on the forces behind productivity decline in the Rwandan agricultural sector. The results are based on collaborative research between the Rwandan Ministry of Agriculture and Michigan State University.Among the key findings are that Rwandan farmers need to sustain and intensify their farming by pro-tecting the soil against erosion.

Cropping frequency and area response to climate variability can exceed yield response

Décembre, 2015
Brésil

The researchers have used evidence from Mato Grosso, Brazil, to show that changes in agricultural output stemming from the sensitivity of cropland area and cropping frequency to interannual climate variability are of similar magnitude to agricultural output changes associated with the sensitivity of crop yield to interannual climate variability.

Agroforestry and Forestry in Sulawesi series: profitability and land use systems in South and Southeast Sulawesi

Décembre, 2011
Indonésie
Asie méridionale

This profitability assessment is an early effort to generate baseline information for the Agroforestry and Forestry in Sulawesi: Linking Knowledge with Action project the ‘AgFor project’ , for implementation in two provinces, South Sulawesi and Southeast Sulawesi. The study collected information on existing farming systems and estimated profitability for each land use. The profitability indicators used in the study are: net present value NPV , equivalent annuity and return to labour.

Land degradation, stocking rates and conservation policies in the communal rangelands of Botswana and Zimbabwe

Décembre, 1989
Botswana
Zimbabwe
Afrique sub-saharienne

This article suggests that communual rangeland management policies in Botswana and Zimbabwe are based on incorrect technical assumptions about the stability of semiarid rangelands, the nature of rangeland degradation, and the benefits of destocking. Consequently, inappropriate policies, stressing the need to destock and stabilise the rangelands, are pursued.Acknowledgement of the great instability but intrinsic resilience of rangeland would encourage the Governments to more favourable regard the opportunistic stocking strategies of the agro-pastoralists of the Communual Areas.

High-altitude rangelands and their interfaces in the Hindu Kush Himalayas

Janvier, 2013

The interfaces between high-altitude rangelands and other ecosystems in the Hindu Kush Himalayan region such as forests, wetlands, and agricultural land are suffering from degradation, desertification, and soil erosion, which are further aggravated by climatic and anthropogenic factors. However, more information is needed on the ecological role of high-altitude rangelands and their interfaces as a basis for developing and implementing plans for conservation and sustainable management of these fragile ecosystems.

Drivers of household food availability in sub-Saharan Africa based on big data from small farms

Décembre, 2014
Afrique sub-saharienne
Afrique septentrionale
Asie occidentale

Achieving sustainable food security (i.e., the basic right of people to produce and/or purchase the food they need, without harming the social and biophysical environment) is a major challenge in a world of rapid human population growth, large-scale changes in economic development and in the face of climate change.

In sub-Saharan Africa (SSA), production on smallholder farms is critical to the food security of the rural poor and contributes the majority of food production at the national level.

Integrated agriculture enhances farm productivity and livelihoods in agro-biodiversity hotspots

Janvier, 2014
Inde
Asie méridionale

India is home to incredible diversity in plant and animal species and is ranked among the richest areas of biodiversity in the world. Unfortunately, much of this diversity is being eroded at an alarming rate, largely due to habitat destruction and invasion by alien species. In the hilly regions of southern India, known
