using agricultural land classification database generalization as an example.The hierarchy of neighborhood relationship is analyzed based on multiple attributes of thematic data.This method is applied to polygons aggregation and amalgamation.The work flow of polygons merger in agricultural land ...
RP and CAP results were overlaid with supervised classification results to determine the amount of land used for agricultural purposes within each suitability class. It was determined that currently, for agricultural purposes, 0.04km2(RP) or 0.88km2(CAP) of very unsuitable land (1) is used, ...
At the regional level across all 12 countries, a “U-Shaped” relationship was found across land use classes and the odds of childhood malaria, when ordered to reflect the transitions from natural to fully converted land; that is, natural forest cover (highest odds) to mosaics (lowest odds) ...
Agriculture has been implicated as a potential driver of human infectious diseases. However, the generality of disease-agriculture relationships has not been systematically assessed, hindering efforts to incorporate human health considerations into land-use and development policies. Here we perform a meta-...
In application, the parameters of great soil group, land use capability class, land use capability sub-class, soil depth, slope, aspect, elevation, erosion degree and other soil properties were used. In determining the weights of the parameters, experts' opinions were consulted, and the ...
Land UseHistoryThis study aims to explain effects of soil textural class, topography, land use, and land use history on soil greenhouse gas (GHG) fluxes in the Lake Victoria region. We measured GHG fluxes from intact soil cores collected in Rakai, Uganda, an area characterized by low-input ...
摘要: This article looks at land in perhaps its most bask and fundamental purpose--that of agriculture. The authors summarize why this market segment has become an important asset class for investors and what are the historical and future valuation and demand trends. [ABSTRACT FROM AUTHOR]...

With a growing body of research associating livestock agriculture with faster global warming, higher health costs and greater land requirements, a drastic shift towards plant-based diets is often suggested as an effective all-round solution. Implicitly, this argument is predicated on the assumption tha...
China’s agricultural sector is dominated by smallholder farms, which mostly exhibit relatively low nutrient use efficiency, low agricultural income and substantial non-point-source pollution. Here we assess the spatial feasibility and cost-effectiveness of agricultural land consolidation in China by integr...
