Estimation of the fertilizer response of maize and bean intercropping using sole crop response equations
Maize (Zea mays L.) and bean (Phaseolus vulgaris L.) are commonly grown in association in eastern and southern Africa. Results from 64-fertilizer response trials conducted in Kenya were used to study the relationship between maize monoculture response to fertilizer nitrogen and phosphorus and the intercrop response. The intercrop was more productive that the monoculture with no fertilizer applied, but overall responses of systems to applied nutrients did not differ. Maize, both in monoculture and intercropped, responded more frequently to applied N than did the intercropped bean.

Evaluating Land Management Options (ELMO)
- Without understanding what (and why) farmers need and are able to carry out, SLM uptake is likely to remain very limited.
- ELMO is participatory tool to assessing farmers’ land management decision preferences & trade-offs.
- Is mainly concerned with identifying the social and economic drivers of land management decisions & understanding farmers’ preferences for different SLM practices.
- Intention is to better understand farmers’ own perceptions and explanations of the benefits, costs, advantages, disadvantages & tradeoffs associated with different la
Evaluating the flow regulating effects of ecosystems in the Mekong and Volta river basins
By altering evapotranspiration and influencing how water is routed and stored in a basin, natural and agrarian ecosystems affect river flow. To quantify the impact of ecosystems on streamflow in two large river basins in Asia and Africa, simple statistical relationships were calculated, enabling flow characteristics to be ascertained from basic catchment features. This approach allows the impact of specified land-use change on streamflow to be determined.
Evaluation des ressources en eau du bassin de la Volta. In French
Le projet « WISE UP to climate » vise a demontrer l'utilite des infrastructures naturelles comme une « solution basee sur la nature » pour l'adaptation au changement climatique et le developpement durable. Dans le bassin de la Volta, les infrastructures naturelles, comme les construites, offrent des benefices pour la subsistance des personnes. Comprendre les interrelations entre ces deux types d'infrastructures est une condition indispensable a une gestion et un developpement durables des ressources en eau.
