General Data
Natural Earth
"Natural Earth is a public domain map dataset available at 1:10m, 1:50m, and 1:110 million scales. Featuring tightly integrated vector and raster data, with Natural Earth you can make a variety of visually pleasing, well-crafted maps with cartography or GIS software." These are extremely useful e.g. for making "establishing map" showing the location of a study area relative to a country, etc. 1:10m means a standard econ paper figure filling about 15cm represents about 1,500 km. Includes the very beautiful Gray Earth series of shaded relief maps.

The FAO collects and processes a variety of geographic data to develop estimates for the productivity of crops under various scenarios. Their web platform disseminates data on five basic thematic areas:
The FAO collects and processes a variety of geographic data to develop estimates for the productivity of crops under various scenarios. Their web platform disseminates data on five basic thematic areas:
- Land and Water resources, including soil resources, terrain resources, land cover, protected areas and selected socio economic and demographic data;
- Agro-climatic resources, including a variety of climatic indicators;
- Suitability and potential yields for up to 280 crops/land utilization types under alternative input and management levels for historical, current and future climate conditions;
- Downscaled actual yields and production of the main crop commodities;
- Yield and production gaps, , in terms of ratios and differences between actual yield and production and potentials for main crops.
