Understanding relations between pastoralism and its changing natural environment

The competition for land has become an issue of major concern and cause of conflict, especially between pastoralists and crop farmers, but also between pastoralists and nature conservation institutions. The Biosphere Reserve of W in Benin Republic (WBR) and its surrounding lands are located in the agro-pastoral contact zone in West Africa, enabling competition for land, and affecting the relations between pastoralism and its environment. The general aim of this thesis, therefore, was to understand the relations between pastoralism and its changing natural environment. In terms of land use change, cropland area around WBR expanded, whereas grazing area reduced. Population growth and rising demand for food crops and cash crops were the indirect causes of this loss of grazing lands. Competing claims over land existed between crop farmers and pastoralists, among crop farmers, and among crop farmers, pastoralists, and the WBR authority due to past expropriation, unfair and incomplete implementation of the WBR regulations and the increasing shift of pastoral lifestyle to crop farming. In terms of effects of grazing on plant communities, highly grazed sites had more species diversity than lowly grazed sites. This suggests that the current level of grazing was not damaging plant communities’ diversity. Annual species dominated the surveyed vegetation, suggesting that restoration of grazing lands with perennials requires human intervention. Herding involves taking decisions and moving of livestock in search for feed. Herding decisions are based on traditional ecological knowledge (TEK) of soil, forage and livestock. Pastoralists identified five different soils, which they selected for herding at different times of the year. Perennial grasses were perceived of high nutritional quality, whereas annuals were of low nutritional quality. Afzelia africana had high perceived quality for milk production, whereas Khaya senegalensis had the highest perceived quality for meat production, health and strength. In decision making for herding, pastoralists used a holistic approach, combining TEK about soil, vegetation and livestock, in a structured and prioritised reasoning. Changes in the pastoral system can lead to changes in desired livestock traits, which may lead to loss of indigenous breeds. Keteeji was valued for its endurance and tolerance to trypanosomiasis, Bodeeji was highly valued for endurance and Gudali was perceived of high value for meat and milk production, but of low value for endurance. To deal with the changing and unfavourable conditions of their environment, pastoralists preferred cattle breeds performing well on adaptive traits i.e. withstanding hunger, intelligence, and withstanding disease. Our results suggest that pastoralism is under pressure and that its survival depends on policies. In the pessimistic scenario, i.e. without any change, pastoralists will use, likely, the stepping-out strategy in the future. In the optimistic scenario, two possible institutional interventions could help maintaining pastoralism in the region: payments for ecosystem services provided by pastoralism, and association of pastoralism with nature conservation. In practice, however, the implementation of these two interventions is very challenging, which implies an increasing vulnerability of pastoralists and pastoral lifestyle.
