Custodian farmers of agricultural biodiversity: selected profiles from South and South East Asia

Diciembre, 2012
India
Asia meridional

Agriculture is the largest global user of biodiversity. Over-reliance on a handful of crops puts global food security at great risk especially in the context of climate change. Selected and used by generations of farmers, agricultural biodiversity contributes to reducing malnutrition, alleviating poverty and combating climate change challenges. This diversity has been in decline for decades and is now in danger of disappearing and efforts needed to conserve them using both ex situ and in situ approaches.

Fuelling exclusion? The biofuels boom and poor people's access to land

Diciembre, 2007
África subsahariana
América Latina y el Caribe
Asia meridional

The policy debate about the merits and demerits of biofuels is growing and changing rapidly, with concerns being voiced over their effectiveness for mitigating climate change, role in recent food price hikes and social environmental impacts. This study contributes to these debates through examining the current and likely future impacts of the increasing spread of biofuels on access to land in producer countries, particularly for poorer rural people. It draws on a literature review of evidence drawn from diverse contexts across Africa, Asia and Latin America.

Sustainable Intensification: A New Paradigm for African Agriculture

Diciembre, 2012
África subsahariana

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

Diciembre, 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.

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

Diciembre, 2011
Lesotho
África subsahariana

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

Diciembre, 2013
Granada
San Vicente y las Granadinas
América Latina y el Caribe

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

Diciembre, 2011
Indonesia
Viet Nam
Asia meridional
Asia oriental
Oceanía

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.

Adoption potential of rotational hedgerow intercropping in the humid lowlands of Cameroon

Diciembre, 1999
Camerún
África subsahariana

Reports on and on-farm evaluation of hedgerow intercropping by the IRA/ ICRAF Programme in the lowlands of Cameroon, which has been in progress since 1988. Throughout the years the biophysical performance of the system was found to be inferior under farmer management on farm to that achieved on station. At the same time, farmers' interest in the technology was far below the expectations.
