This study focuses on theWest Usambara Highlands of Tanzania,
an area where knowledge about SLM measures is widely available,
but where only few farm households invest in SLM (Tenge, 2005).
Little is knownabout whatis limiting these farmers to investinSLM,
and which lessons to include in a strategy to promote spreading of
SLM investments. This study fills this gap, and was conducted with
the objective to determine key socio-economic factors influencing
farm households to invest in SLM on upland rain-fed fields, and as
such generate lessons for a participatory strategy to spread SLM in
the West Usambara Highlands
