Welcome to the John Wesley Powell Center Working Group on Global Croplands and Water Use for Food Security in the 21st Century

Recent Highlights are our Factsheet, Newest Impact Publication, Global Food Security Article for Rio+20, Public Lecture and a Cropland Algorithm Paper.

Two Remote Sensing of Global Croplands Positions: Research Scientist position in Remote Sensing & Postdoctoral position in Remote Sensing (download the job postings here).

Overarching Goal

The overarching goal is to create a "knowledge gateway" on data, products, and algorithms pertaining to global croplands and their water use that contributes towards global food security in the twenty-first century

Spatial Distribution of Crops

The image (click image to enlarge) shows spatial distribution of global cropland areas (~1.5 billion hectares) and five dominant crop types (wheat, rice, maize, barley and soybeans). This composite map was produced by Thenkabail and Gumma through spatial modeling involving remote sensing derived global irrigated and rainfed croplands (Thenkabail et al., 2011, 2009a, 2009b) and five dominant global crop types from other sources (Ramankutty et al. (2008), Monfreda et al. (2008), and Portman et al. (2009)). The 5 crops constitute about 60% of all global cropland areas.
