The urban-rural water interface: a preliminary study in Burkina Faso

Décembre, 2014
Burkina Faso

Decisions on water allocation and infrastructure lie at the heart of development planning in semi-arid lands. On paper, the laws and policies of Burkina Faso accord equal entitlement to drinking water for the residents of cities and the residents of small towns and villages.

In practice, Ouagadougou’s status as economic and administrative capital gives it much greater power to plan for and mobilise investment for its own water supplies. The Ziga project (in two phases) has been designed to secure bulk water supply for Ouagadougou until 2030.

Shaping forest safety nets with markets: Adaptation to climate change under changing roles of tropical forests in Congo Basin

Décembre, 2009
République démocratique du Congo
Afrique sub-saharienne

This paper explores the role of markets for Non-Timber Forest Products (NTFPs) in facilitating climate change adaptation of local communities in the Congo Basin. While forests are regarded as safety nets in the climate change movement, emerging market systems that facilitate a shift to a more cash-based economy may reduce this traditional function. This paper contends that the size of trade in timber and non-timber forest products, overexploitation, and unsustainable practices threaten the integrity of forest ecosystems and the goods and services they provide.

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

Décembre, 2011
Indonésie
Viet Nam
Asie méridionale
Asie orientale
Océanie

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

Décembre, 1999
Cameroun
Afrique sub-saharienne

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.

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.

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.

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.
