Forests and climate change: role of forest lands as carbon sinks

Décembre, 1996

Forests potentially contribute to global climate change through their influence on the global carbon (C) cycle. They store large quantities of C in vegetation and soil, exchange C with the atmosphere through photosynthesis and respiration, are sources of atmospheric C when they are disturbed, become atmospheric C sinks during abandonment and regrowth after disturbance, and can be managed to alter their role in the C cycle. The world's forest contain about 830 Pg C (1015 g) in their vegetation and soil, with about 1.5 times as much in soil as in vegetation.

Climate change and decline in water resources in Kikuletwa Catchment, Pangani, Northern Tanzania

Janvier, 2013
Tanzania

The study assessed the sensitivity of hydrology and water resources to climate variation in Kikuletwa Catchment, Pangani Basin, northern Tanzania using 30 years of river level and climate data as well as questionnaire, focused group discussion (FGD) and participant observation. It concludes that there is a significant association between mean annual river level for Kikuletwa River and mean annual rainfall over the tree decades.

Using adaptation tipping points to prepare for climate change and sea level rise: a case study in the Netherlands

Décembre, 2009
Pays-Bas

Studies on the impact of climate change and sea level rise usually rake climate scenarios as their starting point. To support long-term water management planning int he Netherlands, this paper starts at the opposite end of the effect chain. The study refers to three aspects of water management:

flood defence
drinking water supply
protection of the Rotterdam harbour.

The Nile River Basin: water, agriculture, governance and livelihoods

Décembre, 2011
Afrique sub-saharienne

This book covers the whole Nile Basin and is based on the results of three major research projects supported by the Challenge Program on Water and Food (CPWF). It provides unique and up-to-date insights on agriculture, water resources, governance, poverty, productivity, upstream–downstream linkages, innovations, future plans and their implications. Specifically, the book elaborates the history, and the major current and future challenges and opportunities, of the Nile River Basin.

The Chinyanja Triangle in the Zambezi River Basin, Southern Africa: status of, and prospects for, agriculture, natural resources management and rural development

Décembre, 2013
Afrique sub-saharienne

This paper, which focuses on the Chinyanja Triangle (CT), an area inside the Zambezi River Basin, characterises three distinct farming subsystems across rainfall gradients, namely maize-beans-fish, sorghum-millet-livestock and the livestock-dominated subsystem. It presents the socioeconomic characteristics, historical drivers of change, resources use and management (water, land, forestry) and the institutional disincentives affecting agricultural production and productivity in the region.

Doubling irrigation for southern Africa – do we have enough water and where is the hope?

Décembre, 2011
Afrique sub-saharienne

Southern Africa Development Communality (SADC) through its Regional Indicative Strategic Development Plan (RISDP) has set up an ambitious goal to double irrigation by 2015, which it sees as important component to sustain regional development and ensure food security. While the target timeline is questionable with year 2015 fast approaching, the goal to increase irrigated areas to 7% is certainly valid and has significant implications for regional food security and livelihood of rural population.

Gender and Peri-urban water security

Décembre, 2012
Inde
Népal

As geographical areas subjected to rapid urbanisation and constantly  changing land use, peri-urban sites offer women and men greater economic opportunities.At the sametime,peri-urbanresidents are also drawn away from traditionalmeans of livelihood.As the city encroaches into prime agricultural lands in the fringe areas,occupations become more subsistence in nature.  This increases women's workload. Often women, who migrate from rural areas after marriage and settle in peri-urban zones,face enormous challenges in accessing water.

Biodiversity and Development of the Hydropower Sector: Lessons from the Vietnamese Experience

Décembre, 2009
Viet Nam
Océanie
Asie orientale
Asie méridionale

Climate change prompts policymakers to pursue a low carbon energy pathway in order to reduce greenhouse gas emissions. However, this can lead to trade-offs with other sustainability objectives. This policy brief outlines key issues relating to biodiversity and the development of the hydropower sector in Vietnam. It is aimed at informing policymakers, civil society and donors. It argues that the large-scale development of the country’s hydropower sector is being undertaken without due consideration of the impacts that this is having on the nation’s biodiversity.

On target for people and planet: Setting and achieving water related Sustainable Development Goals

Décembre, 2013

This report cautions against an overly rigid approach to the Sustainable Development Goals (SDGs), which it argues could limit development options for poor countries, particularly in how they are able to manage critical water resources. It identifies key challenges such as setting realistic targets, carefully considering the local context to address the needs of the poor, and promoting sustainable water resources development in a way that values healthy ecosystems.

Governing the forests: an institutional analysis of REDD+ and community forest management in Asia

Asie méridionale

This report examines the history, structure and monitoring mechanisms of REDD+ to better understand how it impacts upon, and interacts with, Community Forest Management (CFM). It presents case studies of CFM and REDD+ governance from Bangladesh, Indonesia and India, and concludes with some lessons learned.REDD+ is an example of multilevel governance that uses a variety of institutional structures and processes aimed at promoting sustainable management of forests, including financial incentives to reduce deforestation and forest degradation.

Water-smart agriculture in East Africa

Janvier, 2015
Afrique sub-saharienne

The inspiration for this sourcebook came from a 2014 meeting of researchers, practitioners and policy makers in Addis Ababa under the auspices of an event co-convened by the Global Water Initiative East Africa (GWI EA), the International Water Management Institute (IWMI) and the Water, Land and Ecosystems programme of the CG system. The event agreed there was a pressing need for greater regional consolidation of knowledge on improving water management for smallholder farmers.

The status of agricultural water use, access, and productivity in the Limpopo Basin — opportunities for poverty alleviation

Décembre, 2009
Afrique du Sud
Botswana
Zimbabwe

The Limpopo River Basin is home to 14,000,000 people, at least half of whom live in rural areas. Over ten million South Africans live in the basin - nearly 25% of the national population. The remaining population live in Botswana - one million people, nearly 60% of the national population - Mozambique and Zimbabwe. While there are no major cities located on the river, several major urban areas in or adjacent to the basin impact water availability including quality.
