      abstract = {Technological change in agriculture plays a decisive role  for meeting future demands for agricultural goods.  Especially in the longer run, i.e. several decades,  technological change will be one of the major determinants  of agricultural production. However, up to now, most  agricultural sector models and models on land use change  have used technological change as an exogenous input due to  various information and data deficiencies. This paper  provides a first attempt towards an endogenous  implementation based on a measure of agricultural land-use  intensity, called τ -factor. We relate this measure to  empirical data on investments in technological change as  well as production costs. Our estimated yield elasticity  with respect to research investments is 0.24 and production  costs per area increase linearly with an increasing yield  level. Having implemented this approach in the global  land-use model MAgPIE (”Model of Agricultural Production  and its Impact on the Environment”) we are able to project  about required yield growth rates in the future. Highest  future yield increases are obtained for Sub-Saharan Africa,  the Middle East and South Asia. A validation with FAO data  for the period 1995-2005 shows that our model behaviour is  in line with recent observations.},
