Actual Crop Water Use in Project Countries: A Synthesis at the Regional Level
This report aims to synthesize the results of a crop water use study conducted by country teams of the GEF/World Bank project, Regional Climate, Water, and Agriculture: Impacts on and Adaptation of Agro-ecological Systems in Africa. It also presents the results of the second phase of the study based on climate change scenarios, conducted by the South Africa country team. The actual ...
The Health Impact of Extreme Weather Events in Sub-Saharan Africa
Extreme weather events are known to have serious consequences for human health and are predicted to increase in frequency as a result of climate change. Africa is one of the regions that risks being most seriously affected. This paper quantifies the impact of extreme rainfall and temperature events on the incidence of diarrhea, malnutrition and mortality in young children in Sub-Saharan Africa. ...
The social dimensions of adaptation to climate change in Ghana
The program's objective is to assist decision makers in developing countries in integrating adaptation measures into national development strategies, policies, and budgets. The economics of adaptation to climate change is a new research area and no agreed methodology to assess overall costs has yet emerged. The study is intended to help decision makers in developing countries to better ...
Climate Change and Water
Observational records and climate projections provide abundant evidence that freshwater
resources are vulnerable and have the potential to be strongly impacted by climate change,
with wide-ranging consequences on human societies and ecosystems.
Observed warming over several decades has been linked to changes in the large-scale
hydrological cycle such as: increasing atmospheric water vapour ...
Economics of rainwater harvesting for crop enterprises in semi-arid areas of East Africa
This paper presents an analysis of economics of rainwater harvesting by poor farmers in Tanzania.
A questionnaire was used to survey 120 households to obtain information on the performance of their
enterprises over 6 years (1998–2003). The information was mainly based on recollection as few
farmers kept detailed records. Actual monitoring and measurements of yield and inputs was done in
Managing the changing health risks of climate change
Climate change will make the control of many climate-sensitive
health determinants and outcomes more difficult. Because the
health determinants and outcomes that are projected to
increase with climate change are problems today, in most
cases the primary response will be to enhance current health
risk management activities. However, that is unlikely to be
sufficient to address changing disease ...
Methods for studying collective action in rural development
With renewed recognition of the importance of collective action in many aspects of agriculture,
natural resource management, and rural development programmes in developing countries,
there is a need for research on the factors that affect its emergence, as well as its
performance. Yet because of its dynamic nature, collective action is difficult to measure and
study. This article discusses ways ...
SENSITIVITY OF HYDROPOWER PERFORMANCE TO CLIMATE CHANGE
One way of reducing the extent of climate change is to replace fossil-fuelled electricity generation with renewable sources, including hydropower. However, simultaneous changes in climate may alter the available hydropower resource, threatening the financial viability of schemes. To illustrate the potential problem, a sensitivity analysis is presented that considers the impact of altered ...
The poverty implications of climate-induced crop yield changes by 2030
Accumulating evidence suggests that agricultural production could be greatly affected by climate
change, but there remains little quantitative understanding of how these agricultural impacts would
affect economic livelihoods in poor countries. Here we consider three scenarios of agricultural impacts of
climate change by 2030 (impacts resulting in low, medium, or high productivity) and evaluate ...
Darfur: rainfall and conflict
Data on rainfall patterns only weakly corroborate the claim that climate change explains the
Darfur conflict that began in 2003 and has claimed more than 200 000 lives and displaced more
than two million persons. Rainfall in Darfur did not decline significantly in the years prior to
the eruption of major conflict in 2003; rainfall exhibited a flat trend in the thirty years preceding
the conflict ...
Perceptions of climate risk in Mozambique: Implications for the success of adaptation strategies
Policies to promote adaptation climate risks often rely on the willing cooperation of the intended
beneficiaries. If these beneficiaries disagree with policy makers and program managers about the need
for adaptation, or the effectiveness of the measures they are being asked to undertake, then
implementation of the policies will fail. A case study of a resettlement program in Mozambique shows
