Abstract Environmental change in the West African Sahel, including land cover change, has been a prominent issue in sustainability and development debates and research for the last half century. This paper provides a reminder that historical changes in the use of land resources are embedded in a complex web of driving forces, which it is crucial to keep in mind in order to appreciate the role of different factors of change. The article seeks to identify the wide range of influential events that have modified land use decisions in Burkina Faso and Niger for the period from before Independence (1960) until the present day. The material originates from a thorough consultation of local literature as well as from national expert knowledge. A 'timeline heuristic' provides an overview of the co-evolution of major issues characterizing the 'demographic and socioeconomic setting', the 'political and institutional setting' and the 'biophysical setting', which enable and constrain changes in the use of land. When possible, the impact of changes is specified in detail in terms of land use patterns, food security, environment, agricultural practices or pastoral practices. An overview matrix indicates how environmental and land use related processes in the Sahel are embedded in many constantly changing influential conditions. On this background, the article cautions against translating insights gained from past experience into generic traits of human-environment dynamics, which can be immediately used to predict plausible directions of future changes in pressures on land and the environment. Key words: Sahel, Sustainability research, institutions, policies

The Sudano-Sahelian zone of West Africa has experienced recurrent droughts since the mid-1970s and today there is considerable concern for how this region will be able to adapt to future climate change. To develop well targeted adaptation strategies, the relative importance of climate factors as drivers of land use and livelihood change need to be better understood. Based on the perceptions of 1249 households in five countries across an annual rainfall gradient of 400-900 mm, we provide an estimate of the relative weight of climate factors as drivers of changes in rural households during the past 20 years. Climate factors, mainly inadequate rainfall, are perceived by 30-50% of households to be a cause of decreasing rainfed crop production, whereas a wide range of other factors explains the remaining 50-70%. Climate factors are much less important for decreasing livestock production and pasture areas. Increases in pasture are also observed and caused by improved tenure in the driest zone. Adaptation strategies to declining crop production include 'prayer' and migration in the 400-500 mm zone; reforestation, migration, and government support in the 500-700 mm zone; and soil improvement in the 700-900 mm zone. Declining livestock holdings are countered by improved fodder resources and veterinary services. It is concluded that although rainfed crop production is mainly constrained by climate factors, livestock and pasture are less climate sensitive in all rainfall zones. This needs to be reflected in national adaptation strategies in the region.
