Humans have transformed the surface of the planet through agricultural activities, and today, ∼12% of the land surface is used for cultivation and another 22% is used for pastures and rangelands. In this paper, we have synthesized satellite‐derived land cover data and agricultural census data to produce global data sets of the distribution of 18 major crops across the world. The resulting data are representative of the early 1990s, have a spatial resolution of 5 min. (∼10 km), and describe the fraction of a grid cell occupied by each of the 18 crops. The global crop data are consistent with our knowledge of agricultural geography, and compares favorably to another existing data set that partially overlaps with our product. We have also analyzed how different crops are grown in combination to form major crop belts throughout the world. Further, we analyzed the patterns of crop diversification across the world. While these data are not sufficiently accurate at local scales, they can be used to analyze crop geography in a regional‐to‐global context. They can also be used to understand the global patterns of farming systems, in analyses of food security, and within global ecosystem and climate models to understand the environmental consequences of cultivation.
1. Introduction
[2] Humans dominate the landscape in nearly every corner of the planet. Today, croplands occupy nearly 18 million km2 (an area roughly the size of South America), pastures take up another 34 million km2 (an area roughly the size of Africa), and urban areas use roughly 2.5 million km2 (an area roughly the size of a third of Europe) [Klein Goldewijk , 2001; Ramankutty and Foley , 1998; Turner et al. , 1993]. Altogether, these three anthropogenic ecosystems currently occupy over a third of the global land surface.
[3] Human land use practices have enormous consequences for the environment. While croplands and pastures provide food for the world's population, agricultural practices have, to a large degree, led to the clearing of many forests [Goudie , 2000]. Human land use practices have also degraded many soils [Meyer and Turner , 1994], influenced global and regional climates [Betts , 1999; Bounoua et al. , 2002; Brovkin et al. , 1999; Pielke et al. , 2002; Zhao and Pitman , 2002], changed the global cycles of carbon, nitrogen, and water [Houghton et al. , 1999; Vitousek et al. , 1997; Postel et al. , 1996], induced the loss of biodiversity [Dale et al. , 2000; Pearce , 2001; McNeely , 1992], affected geomorphic processes, and changed the quality of many natural waterways [Goudie , 2000]..
