This reports summarizes and synthesizes activities and achievements of the CGIAR Challenge Program on Water and Food (CPWF) through the end of 2007. The CPWF is an intiative of the CGIAR designed to take on the global challenge of water scarcity and food security.

The Niger River Basin covers 7.5% of the African continent, and is shared between nine riparian
countries. The basin countries can be categorized into water resources producers, consumers, both
producers and consumers, and minimum contributors and consumers. As in the case for most
transboundary rivers, upstream and downstream conflicts emanating from the development and
utilization of the Niger River are inevitable and are expected to be intense, particularly given the

The Basin Focal Project Volta (BFP Volta) was developed along three main steps:
Assessment of present conditions of the distribution of rural poverty, of farming
systems with their productivity and water productivity;
Analysis of opportunities and risks, especially under the double pressure of demography
and possible climate change, and modeling of water resources to identify sensitivity of
water allocation to development and climate scenarios; and
Identification of research gaps and implementation plan.

The livestock sector is one of the major contributors in agriculture, by some estimates
contributing up to 18% of the global greenhouse gas (GHG) emissions. Of this, about one
third is reported to be due to land use change associated with livestock production, another
one third is nitrous oxide from manure and slurry management, and roughly 25% is attributed
to methane emissions from ruminant digestion. Recent analysis suggests that developing
world regions contribute about two thirds of the global emissions from ruminants, with sub-

The CPWF was designed to be different. Developed in response to a call for change in a previous round of Consultative Group on International Agricultural Research (CGIAR) system
reform, the CPWF was intended to foster cross-CGIAR cooperation and find ways to bring in new partners. Over time the CPWF has successfully broadened the CGIAR’s sources of
innovative research on water and food. Through its broad partnerships, the program conducts research that leads to positive impact on the poor and to policy change. The CPWF does this by

The fire severity of the 2013–2014 fire season within Sudanian ecosystems in Burkina Faso was evaluated from Landsat 8 images using derivatives of the Normalized Burn Ratio algorithm (NBR). The relationship between the image-derived severity and the field observed severity i.e. Composite Burn Index (CBI) was best described by a nonlinear model of the form y = a + b*EXP(CBI *c) (R2 = 0.66). Classification of the image-derived burned area into burn severity classes achieved a classification Kappa accuracy statistic of 0.56.

The Atankwidi Catchment, which lies in the White Volta Basin in West Africa, is intensively cultivated by locals for economic gains. During dry seasons, farmers irrigate their crops, chiefly tomatoes, using shallow groundwater harvested from shallow ponds they dig using simple tools like an axe, hoe, bucket and bowls. Recent expansion in cultivated areas has brought to the fore the need to estimate the volume of shallow groundwater stored in the catchment’s underlying aquifer and to what extent it can sustain the incremental growth in irrigated areas.
