[1] 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.

Abstract A process-based terrestrial ecosystem model, Agro-IBIS, was used to simulate maize yield in a 13-state region of the U.S. Corn Belt from 1958 to 1994 across a 0.5° terrestrial grid. For validation, county-level census [U.S. Department of Agriculture (USDA)] data of yield were detrended to calculate annual yield residuals. Daily atmospheric inputs from the National Centers for Environmental Prediction–National Center for Atmospheric Research (NCEP–NCAR) reanalysis were used in conjunctio...

[1] The increased use of nitrogen (N) fertilizers in the Mississippi Basin since the 1950s is partially responsible for an increase in crop production, but also a massive increase in nitrate export by the Mississippi River. We used the IBIS terrestrial ecosystem model, including new maize and soybean submodels, and the HYDRA hydrological transport model to investigate the role of climate variability, land cover and N-fertilizer application on crop yield, N cycling and nitrate export in the Upper...

[1] The global distribution of C3 and C4 plants is required for accurately simulating exchanges of CO2, water, and energy between the land surface and atmosphere. It is also important to know the C3/C4 distribution for simulations of the carbon isotope composition of atmospheric CO2 owing to the distinct fractionations displayed by each photosynthetic type. Large areas of the land surface are spatial and temporal mosaics of both photosynthetic types. We developed an approach for capturing this h...

A series of 17-year integrations using the NCAR CCM3 (at about 2.8° × 2.8° resolution) were performed to investigate the regional-scale impact of land cover change. Our aim was to determine the impact of historical land cover change on the regional-scale climate over the regions where most change occurred: Europe, India and China. The change from natural to current land cover was estimated using BIOME3 to predict the natural vegetation type, and then using remotely sensed data to estimate the lo...

This study investigates the effects of large-scale human modification of land cover on regional and global climate. A general circulation model (Colorado State University GCM) coupled to a biophysically-based land surface model (SiB2) was used to run two 15-yr climate simulations. The control run used current vegetation distribution as observed by satellite for the year 1987 to derive the vegetation's physiological and morphological properties. The twin simulation used a realistic approximation ...

ABSTRACT Forest ecosystems are being degraded and lost because of rapid population change and economic incentives that make forest conversion appear more profitable than forest conservation. All ecological functions of forests are also economic functions. Many important forest functions have no markets, and hence, no apparent economic value, justifying the use of forest land for other purposes. Imputing economic values to nonmarketed benefits has the potential to change radically the way we look...

Testing against historical data is an important step for validating integrated models of global environmental change. Owing to long time lags in the climate system, these models should aim the simulation of the land use dynamics for long periods, i.e., spanning decades up to a century. Developing such models requires understanding of past and current trends and is therefore strongly data dependent. For this purpose, a history database of the global environment has been developed: HYDE. This pape...

In late 2000, the U.S. Geological Survey (USGS) EROS Data Center completed the circa 1992 National Land Cover Data set (NLCD). The NLCD, derived from early 1990s Landsat Thematic Mapper (TM) imagery and other sources of digital data, represents an intermediate-scale national land cover data set. The resolution of this data set lends itself to many regional to national scale investigations, including analyses of water quality, ecosystem health, wildlife habitat, land cover assessment, land use pl...

Being integral to all functions of terrestrial ecosystem, soil is intended to produce food for feeding the growing population of the world. However, food security is facing threat from soil degradation occurring worldwide. Soils degrade due to the exerting pressure from various sectors of the society including urbanization and industrialization. The major driving forces of soil degradation are deforestation, change in land use, soil erosion, uncontrolled grazing, waste disposal, and unscientific...

Abstract Winter wheat is one of the major crops in the Texas High Plains (THP) region, which is facing challenges from climate change (CC) and exhausting irrigation water supplies from the Ogallala Aquifer. The goal of this study was to assess the impacts of CC on winter wheat production in the THP and evaluate potential adaptation strategies using the Decision Support System for Agrotechnology Transfer (DSSAT) CERES-Wheat model. A thorough calibration of the model against field data resulted in...

Abstract Cotton/peanut intercropping and their rotation have been widely studied and adopted in many cotton and peanut growing countries including China. However, it is impossible to harvest two crops in the same year under the cotton/peanut rotation. And continuous cropping constraints as indicated by inhibited crop growth and development as well as yield decline remain under continuous cotton/peanut intercropping. We hypothesized that a combination of intercropping and rotation can resolve the...

Abstract Field burning of rice straw as a method of disposal by farmers is a major concern as the smoke and harmful emissions from it causes dangerous levels of pollution. Seven out of ten cities with the poorest air quality in the world are in India, and paddy field burning has been cited as one of the main reasons. Hazardous emissions from paddy field burning is combined with greenhouse gas emissions from coal fired power plants and cement manufacturing units, causing severe respiratory illnes...

Abstract Presence of cadmium (Cd) in food poses serious risks to human health. Understanding the effects of zinc (Zn) on Cd absorption by crops could help provide a theoretical basis for the treatment with Zn on contaminated soils. In this study, two wheat varieties, differing in grain-Cd accumulation ability (L979, a Cd low-accumulation variety, and H27, a high-accumulation variety) were selected to investigate the effect of Zn addition on Cd toxicity. Cd was applied to nutrient solutions at 0 ...

Abstract Accurately predicting changes in the potential distribution of crops resulting from climate change has great significance for adapting to and mitigating the impacts of climate change and ensuring food security. Based on very large datasets of wheat ( Triticum aestivum L.) occurrence points and the main environmental factors that affect wheat growth, we used the Maxent model to predict the future global potential distribution and land suitability for wheat cultivation under multiple glob...

Global warming is expected to increase the frequency and intensity of severe water scarcity (SWS) events, which negatively affect rain-fed crops such as wheat, a key source of calories and protein for humans. Here, we develop a method to simultaneously quantify SWS over the world’s entire wheat-growing area and calculate the probabilities of multiple/sequential SWS events for baseline and future climates. Our projections show that, without climate change mitigation (representative concentration ...

This paper presents evidence on the relationship between traditional farming practices and the emergence of individualistic culture. It hypothesizes that agricultural legacies have a persistent effect on the prevalence of modern-day individualistic traits. Individualism emerged in societies engaged in the farming of less labor-intensive crops, whereas interdependence emerged in societies engaged in the farming of more labor-intensive crops. The empirical analyses establish that agricultural lega...
