Rainwatch keeps eye on rainfall for West African farmers

NOAA-funded researchers hope a new climate information system they developed will help West African farmers help themselves. Rainwatch is a prototype geographic information system (GIS) that monitors monsoon rainfall and tracks season rainfall attributes. This information is crucial because sub-Saharan Africa depends more strongly and directly on rainfall than any other region on Earth, yet the area has the fewest rainfall monitoring stations and significant delays that occur between data collection and its availability for users. Rainwatch automates and streamlines key aspects of rainfall data management, processing and visualization. A major appeal is its simplicity – all interactive interfaces, symbols and names used are unpretentious and self explanatory. In addition, the system can be used by Africans without any outside assistance such as satellite information. In a successful 2009 demonstration involving seven rain gauge stations in Niger, Rainwatch was shown to directly address the area's need for better rainfall data acquisition, management, representation and rapid dissemination. The programme continued in 2010, when it dramatically showed the return of abundant rainfall. It is expected to expand beyond Niger. Because Rainwatch is simple to operate and more streamlined in design and scope than existing systems, the researchers hope the programme will be adopted and used more widely throughout West Africa where other more complicated rainfall data dissemination systems have had limited success.

UNCCD May-June 2011 newsletter

The latest updates from the UN Convention to Combat Desertification (UNCCD) focus on food security and agricultural resilience in dryland regions. This newsletter offers an analysis of the major policy shifts needed to combat food insecurity and desertification, in the wake of the G8 Summit vision statement on the matter. It also gives an account of the MERET programme, conducted jointly by the Ethiopian government and the UN World Food Programme, meant to improve resilience to drought through environmental rehabilitation. Of interest too is the interview of Allan Savory, founder of the Centre for Holistic Management and the Savory Institute, who sees biodiversity loss as the main cause of desertification and debunks common land management myths. He explains the scientific principles behind his holistic approach to desertification. Finally, the newsletter presents Qatar’s food security programme, meant to tackle chronic water scarcity and exploit arable land in dryland ecosystems to enable self-sufficency in food production.

Centre for training and integrated research in ASAL Development

CETRAD is a Bilateral Institution between the Government of Kenya (through the Ministry of Water and Irrigation) and the Government of Swiss Confederation, through the Centre for Development and Environment of the University of Berne. CETRAD was established in July 2002 as a follow up of the then Laikipia Research Programme (1976 - 1997), and therefore builds on the long term pre-investment research facility.CETRAD is based in Nanyuki, Laikipia District, Kenya. It is concerned with research and training to design strategies for sustainable development, promote land use planning for sustained livelihood and optimal resource use, foster sustainable resource use and management for improved productivity and promote non-farm, non-pastoral enterprises, infrastructure and related services in arid and semi-arid lands (ASAL).

African Drought Monitor

Monitoring drought globally is challenging because of the lack of dense in-situ hydrologic data in many regions. This is particularly problematic for developing regions such as Africa where water information is arguably most needed, but virtually nonexistent on the ground in many regions. A potential way forward is to use a modelling framework that couples available satellite remote sensing and in-situ information. This results in physically consistent and spatially and temporally continuous estimates of the water cycle and drought. A drought monitor based on this framework and an accompanying web-based user interface have been developed by Princeton University, in collaboration with UNESCO, for operational and research use over Africa. Based on macro scale hydrologic modelling, the system ingests available data to provide a real-time assessment of the water cycle and drought conditions, and puts this in the context of the long-term record back to 1950. The data is made available online for drought research and operational use to augment on-the-ground assessments of drought.
