Scaling methods in regional integrated assessments are often adopted as givens, when in fact there are a range of methods that each have their strengths and weaknesses. Methods such as a site within a polygon, spatially uniform grids, grids with rela

The crop simulation model AFRCWHEAT2 was used to predict the effect of climatic change on the yield and development of winter wheat in the UK and durum winter wheat in France. The model simulates crop responses to climatic variables dnd includes the

This review article gives an overview of how satellite observations are used to feed or tune crop models and improve their capability to predict crop yields in a region. Relations between crop characteristics which correspond to models state variable

An algorithm is proposed to determine, pixel per pixel, the bare soil NDVI value using coarse resolution NOAA/AVHRR red and near infrared data. This process is based on the soil line concept. Results obtained over Spain show that this method provide

A linear regression equation is found relating the photosynthetically active radiation intercepted by the canopy (PARi), measured with hemispherical photographs, and both the normalized difference ND and the ratio NIR/R vegetation indices. On the bas
