Erosive rainfall results in the loss of both soil and nutrients, which indirectly triggers soil deterioration and a reduction in land productivity. However, how rainfall affects runoff, soil erosion, and nutrient loss under different crop rotation patterns and topographic factors remains unclear.
Buckwheat is an important coarse grain often grown in China’s marginal and dry mountainous areas; however, few empirical studies have quantified the factors that increase land productivity and encourage buckwheat farmers’ market participation.
Spatio-temporal changes in cultivated land have a profound impact on food security and sustainable development. However, existing studies on spatio-temporal changes in cultivated land mostly focus on single factors, for instance quantity, quality and ecology, that cannot comprehensively reflect the changes in total production capacity and the sustainability of cultivated land.
The Mekong Delta region has been seriously affected by climate change, with increasing temperatures, sea-level rise, and salinization strongly impacting agricultural activities of the region. Recent studies have shown that groundwater exploitation also contributes significantly to land subsidence throughout the delta.
Urbanization imperils agriculture by converting farmland into uncultivable impervious surfaces and other uses that limit land productivity. Despite the considerable loss of productive croplands due to historic urbanization in the United States, little is known about the locations and magnitudes of extant agricultural land still under threat of future urban expansion.
The agricultural sector in Armenia contributes around 20 percent to gross domestic product and provides employment to around 40 percent of the country’s labour force. The backbone of agriculture in the country is represented by smallholders and family farms.
Armenia is a landlocked country in the South Caucasus. After gaining independence from the former Soviet Union, a very difficult socio- economic situation developed in Armenia, with a current high level of poverty. Land privatization has led to excessive land fragmentation and a small average farm size.
In this introductory video to the Global Programme Responsible Land Policy answers are given to what it wants to achieve, how it works and why land rights are so important.
This paper explores the role of the global food system as the principal driver of accelerating biodiversity loss. It explains how food production is degrading or destroying natural habitats and contributing to species extinction.
Most commonly in drylands the salinity levels are always high and evenly dispersed due to this salinity levels the plant cultivated are usually tremendously affected. Normal plants cannot grow in soils with high salinity levels. In this book the authors would like to analyze the effects of human acticities on the salinity lebvels in drylands.
