Trees on farms: an update and reanalysis of agroforestry’s global extent and socio-ecological characteristics

Décembre, 2013

Agroforestry, the inclusion of woody perennials within farming systems, has been widespread throughout the tropics as a traditional land use developed by subsistence farmers and, more recently, as an important livelihoods’ option promoted by land-use managers and international development agencies. Agroforestry systems range from subsistence livestock and pastoral systems to home gardens, alley intercropping, and biomass plantations with a wide diversity of biophysical conditions and socio-ecological characteristics.

Adverse impacts of climate change on development of Bhutan: integrating adaptation into policies and activities

Décembre, 2003
Bhoutan
Asie méridionale

Bhutan is a mountainous landlocked country with a varying climate and rich biodiversity. Despite significant economic progress being made over recent years Bhutan remains a least developed nation with constraints and vulnerabilities adversely affecting its capacity to cope with climate change.The authors recognise that Bhutan’s vulnerability is heightened by low economic strength, inadequate infrastructure, lack of institutional capacity and an agro-based rural economy. Impacts of climate change will have significant implications for the overall development of Bhutan.

Sustainable Intensification: A New Paradigm for African Agriculture

Décembre, 2012
Afrique sub-saharienne

Sub-Saharan Africa is particularly vulnerable to global challenges such as food insecurity, climate change, rural poverty, malnutrition and environmental protection. This puts pressure on the fragile food production system. The term ‘Sustainable Intensification’ – ‘producing more outputs with more efficient use of all inputs on a durable basis, while reducing environmental damage and building resilience, natural capital and the flow of environmental services’ – has become synonymous with big, industrial agriculture.

REDD strategies for high carbon rural development

Décembre, 2007

Large areas of the humid tropics are like mosaics, combining features of forests and agriculture and housing hundreds of millions of people. Land uses that store high quantities of carbon, such as agroforestry and other tree-based systems, make up a large part of those mosaic areas. Yet current discussions on reducing emissions from deforestation and degradation (REDD) within the UNFCCC do not adequately address these land uses as part of a potential mitigation strategy.

Local vulnerability, Forest communities and Forestcarbon conservation: case of southern Cameroon

Janvier, 2013
Cameroun

This research paper, published in the international Journal of Biodiversity and Conservation, reports on a study of two community forests', Nomedjoh and Nkolenyeng, Payment for Ecosystem Services (PES) projects located in south Cameroon. Focus group sessions and household surveys were conducted to examine the relationship between the adaptation of forest communities and the mitigation of forest-carbon conservation, and the impact this has on local vulnerability.

Assessment of the impacts and adaptive capacity of the Machobane farming system to climate change in Lesotho

Décembre, 2011
Lesotho
Afrique sub-saharienne

Agriculture remains a major source of income for more than 80 per cent of the rural population in Lesotho, although the country's arable land is only about nine per cent of the total land area. Moreover, the rural economy has been declining due to poor land and water resources management, unsustainable farming practices and unpredictable weather conditions. Communities living on marginal lands whose livelihoods depend on natural recourses are among the most vulnerable to climate change.

Distribution of mangrove habitats of Grenada and the Grenadines

Décembre, 2013
Grenade
Saint-Vincent-et-les Grenadines
Amérique latine et Caraïbes

Climate change is expected to alter existing coastal habitats in Grenada, jeopardizing the island's mangroves, such as through the conversion of basin mangroves to fringe habitats as storm surges open barrier beaches, increasing tidal action and flood duration.

Likewise, incremental sea level rise and storm overwash can lead to increased salinity within coastal ponds, backwaters, and estuaries.

Each of these processes, acting alone or in concert, can greatly affect colonization by all mangrove species that occur in the region.

Forests and Climate Change Adaptation in Asia

This policy brief examines the role of forests for climate change adaptation in the region of Asia. It is organized into several sections. Firstly, anticipated changes to precipitation and temperature in Asia under a low and a high emissions scenario, between 2010 and 2039, are outlined. Following on from this, the key elements of Forest-Based Adaptation (FBA) are discussed and the current status of FBA in Asia is highlighted. Finally, recommendations aimed at moving forest-based adaptation forward are made.

Biocharred pathways to sustainability? Triple wins, livelihoods and the politics of technological promise

Décembre, 2009

Considerable hype and debate are currently surrounding the potential of biochar (charcoal created through the burning of biomass in low oxygen environments) in climate change mitigation and agriculture. This report attempts to summarise the arguments, assumptions and interests in the biochar debate and offer reflections on its prospects. The report begins by outlining what it calls the triple-win of biochar. The production of biochar can be tuned to release bioenergy or biofuels in the form of syngas and bio-oil, thus providing decarbonised biomass fuel.
