  author={Navin Ramankutty and Jonathan A. Foley and John M. Norman and Kevin Mcsweeney},
  journal={Global Ecology and Biogeography},
Aim This study makes quantitative global estimates of land suitability for cultivation based on climate and soil constraints. It evaluates further the sensitivity of croplands to any possible changes in climate and atmospheric CO 2 concentrations. Location The location is global, geographically explicit. Methods The methods used are spatial data synthesis and analysis and numerical modelling. Results There is a cropland ‘reserve’ of 120%, mainly in tropical South America and Africa. Our climate…

Sensitivity of Cropping Patterns in Africa to Transient Climate Change

The detailed analysis of current cropping areas in Africa presented here reveals significant climate sensitivities of cropland density and distribution across a variety of agro-ecosystems. Based on

Climate change impact on agriculture: Devils Lake basin

Northern Great Plains is one of the most important agricultural regions worldwide. This is also a region expected to be heavily impacted by climate change. This and two other papers in this session

Sensitivity of Global Pasturelands to Climate Variation

Pasturelands are globally extensive, sensitive to climate, and support livestock production systems that provide an essential source of food in many parts of the world. In this paper, we integrate

Land cover change and soil fertility in tropical regions

Land cover changes influence the biogeochemistry, hydrology and climate of the earth. Studies that assessed land cover changes at the global scale mostly focused on: deforestation, cropland

The Sensitivity of Land-Atmosphere Coupling to Modern Agriculture in the Northern Midlatitudes.

The results show that modern intensive agriculture has significant and geographically varying impacts on regional evaporative regimes and background climate conditions, highlighting the need for improved representations of agriculture in global climate models to better account for regional climate impacts and interactions with other anthropogenic forcings.

Multitemporal analysis of cropland transition in a climate-sensitive area: a case study of the arid and semiarid region of northwest China

Land-use change is becoming an important anthropogenic force in the global climate system through alteration of the Earth’s biogeophysical and biogeochemical processes. Cropland, which provides

Land Cover Change and Soil Fertility Decline in Tropical Regions

Land cover changes influence the biogeochemistry, hydrology, and climate of the earth. Studies that assessed land cover changes at the global scale mostly focused on: deforestation, cropland

Spatial Distribution of Global Cultivated Land and Its Variation between 2000 and 2010, from Both Agro-Ecological and Geopolitical Perspectives

Food security requires a thorough understanding of the spatial characteristics of cultivated land changes on a global scale. In particular, the spatial heterogeneity of global cultivated land changes

Agroclimatic conditions in Europe under climate change

To date, projections of European crop yields under climate change have been based almost entirely on the outputs of crop‐growth models. While this strategy can provide good estimates of the effects



Modeling the potential change in yield and distribution of the earth's crops under a warmed climate

The large scale distribution of crops is largely determined by climate. The authors present the results of a climate-crop prediction model based on the U.N. Food and Agriculture Organization

Characterizing patterns of global land use: An analysis of global croplands data

Human activities have shaped significantly the state of terrestrial ecosystems throughout the world. One of the most direct manifestations of human activity within the biosphere has been the

Climatic classification and future global redistribution of agricultural land

Future global carbon (C) cycle dynamics under climates altered by increased concentrations of greenhouse gases (GHGs) will be defined in part by processes which control terrestrial biospher~c C

Climate and plant distribution at global and local scales

This paper investigates, with predictive models, the utility of ecophysiological responses to climate as predictors of plant distribution. At the global scale responses to extreme minimum

Attention to differential patterns and rates of secondary succession on deforested land in the Amazon Basin can help formulate future policies. Amazon deforestation is driven by policies that favor

A digital global map of irrigated areas.

For the purpose of global modeling of water use and crop production, a digital global map of irrigated areas was developed. The map depicts the percentage of each 0.5° by 0.5° cell that was equipped
