A new 1 km global IIASA-IFPRI cropland percentage map for the baseline year 2005 has been developed which integrates a number of individual cropland maps at global to regional to national scales. The individual map products include existing global land cover maps such as GlobCover 2005 and MODIS v.5, regional maps such as AFRICOVER and national map...
Lack of accurate maps on the extent of global cropland, and particularly the spatial distribution of major crop types, hampers policy and strategic investment and could potentially impede efforts to improve food security in an environment characterized by continued market volatility and a changing climate. Here we discuss the pressing need for the ...
The rapid progression of urbanization in periurban areas affects the hydrological cycle of periurban rivers. To quantify these changes, distributed hydrological modelling tools able to simulate the hydrology of peri-urban catchments are being developed. Land cover information is one of the data sources used to define the model mesh and parameters. ...
L’article analyse les dynamiques urbaines et agricoles dans la région de la Lezíria do Tejo, située en troisième couronne métropolitaine de Lisbonne. Cette région est actuellement confrontée au déclin de l’agriculture et à un étalement urbain qui s’effectue principalement par la conversion des sols agricoles. L’une des solutions envisagées par le P...
This paper describes the start of a data sharing process to develop a consolidated community cropland map, which was initiated through a recent workshop on characterizing and validating global agricultural land cover. Participants from different organizations around the world were asked to contribute their various cropland maps prior to the worksho...
