MetadataShow full item record
Although the returns to agricultural production are higher in wetlands, labor use also is much higher than in dryland. The wetlands in the savannas of Africa are a key resource for both farmers and herders. This paper describes the characteristics of wetlands and their relationship to the surrounding savanna lands. It highlights their use for increasing, diversifying and commercializing agricultural production and for livestock production. Restriction of access to wetland for livestock is very serious and leads to conflicts. Technologies, as well as policies, are examined.
