ABSTRACT The concentration of crop cultivation can be measured in terms of spatial clustering and of inequality in the distribution of the cropland area. We used official agricultural statistics at the county level (N = 2,354) for each year from 1980 to 2011 for all of China to analyse the changes in spatial clustering and inequality of overall cropland and of the harvested areas of the five major crops (rice, maize, wheat, soybean, and potato). We quantified the spatial clustering with global… 

Cropland Displacement Drives Carbon Emission of Grain Transport in China

Cropland displacement is a worldwide land-use phenomenon that involves replacing cropland occupied by urbanization with newly developed cropland in remote areas. Large-scale cropland displacement

Spatial agglomeration of drought-affected area detected in northern China

With rapid economic development and population growth, the impacts of drought continue to affect China and the situation will probably be worsened further under projected climate warming. Therefore,

Interprovincial food trade and water resources conservation in China.

Phenology-pigment based automated peanut mapping using sentinel-2 images

ABSTRACT Reliable spatiotemporal crop data are vital for sustainable agricultural management. However, efficient algorithms that can be automatically applied to large regions are scarce, especially



Harvested area gaps in China between 1981 and 2010: Effects of climatic and land management factors

Previous analyses have shown that cropland in China is intensifying, leading to an increase in crop production. However, these output measures leave the potential for further intensification largely

Crop Diversity for Yield Increase

This work tested intercropping of tobacco, maize, sugarcane, potato, wheat and broad bean by relay cropping or by mixing crop species based on differences in their heights, and showed that some combinations increased crop yields for the same season.

Changes in the Potential Multiple Cropping System in Response to Climate Change in China from 1960–2010

The most significant finding of this research was that from the 1960s to the 2000s climate change had led to a significant increase of PMCI by 13% under irrigated scenario and 7% under rain-fed scenario across the whole of China.

Analyzing Agricultural Agglomeration in China

There has been little scholarly research on Chinese agriculture’s geographic pattern of agglomeration and its evolutionary mechanisms, which are essential to sustainable development in China. By

Irrigation investment in China: trends, correlates and impacts

Purpose - – The purpose of this paper is to describe trends in irrigation investment in China’s rural villages in the 2000s, identify the types of villages in which investment occurred and examine

Spatial and temporal changes of vegetable production in China

ABSTRACT Optimizing the distribution of vegetable production requires knowing where vegetables are currently produced and understanding the factors driving structural changes in vegetable production.

Hotspots of land use change in Europe

Assessing changes in the extent and management intensity of land use is crucial to understanding land-system dynamics and their environmental and social outcomes. Yet, changes in the spatial patterns

The Argentine portion of the soybean commodity chain

Since the 1990s the soybean crop has increased in the Southern Cone of Latin America (LA). During this time, Argentina, Brazil, Uruguay, Bolivia and Paraguay have become soybean producers. This
