This report is a synthesis of research implemented for the project on Wetlands-based livelihoods in the Limpopo basin: balancing social welfare and environmental security. The research was motivated by the dependency of many people on wetlands for their livelihoods. It was therefore founded on the basis that the potential of wetlands to contribute to livelihoods is closely related to their ability to maintain ecosytem functions (such as regulating river flows), which is a consequence of their unique hydrological characteristics.

En la Estacion Experimental "Quilichao", del Centro Internacional de Agricultura Tropical (CIAT), depto. del Cauca, Colombia, se realizo un ensayo para evaluar el valor nutritivo y el consumo selectivo de Desmodium ovalifolium CIAT 350. Se usaron ovinos machos enteros de la raza Africanos, con un peso metabolico (P0.75) entre 7.89-9.77, a los cuales se suministro forraje fresco de D. ovalifolium a niveles de 30.245 g de MS/P(0.75) y de 5 edades de corte: 50, 80, 100, 125 y 145 dias; el ultimo corte coincidio con el inicio de la estacion seca.

Supported by the CPWF, this two-year project titled “Valuing the role of living aquatic

resources to rural livelihoods in multiple-use, seasonally-inundated wetlands in the

Yellow River Basin of China, for improved governance” focused on linking the use of

wetlands resources by local communities and value of wetlands ecosystem services with

management implications for the riverine and coastal wetlands in Henan and Shandong

provinces. A study on this Chinese situation of pursuing a rapid development agenda

Interannual variation in rainfall throughout Tamil Nadu has been causing frequent and noticeable land use changes despite the rapid development in groundwater irrigation. Identifying periodically water-stressed areas is the first and crucial step to minimizing negative effects on crop production. Such analysis must be conducted at the basin level as it is an independent water accounting unit.

La cuantificacion analitica de suelos y tejidos vegetales es un instrumento efectivo para interpretar la existencia de deficiencias o excesos de minerales. El uso adecuado de esta informacion influye significativamente en las recomendaciones de fertilizantes. Sin embargo, debe admitirse que existe conflicto en las fases de cuantificacion, interpretacion y recomendacion debido a la alta variabilidad existente en estas fases.
