Gullies are the most energy-efficient way to transport excess runoff from the watershed after a landscape disturbance. The diversity of physical factors that are associated with gully formation makes straightforward interpretation difficult and requires well-founded analysis based on local...

African farm systems remain the least mechanized of all continents. There were substantial state-led efforts to promote agricultural mechanization during the 1960s and 1970s, but these efforts failed, which led to a subsequent neglect of mechanization, both in practice and in academia. In...

Soil degradation in India is estimated to be occurring on 147 million hectares (Mha) of land, including 94 Mha from water erosion, 16 Mha from acidification, 14 Mha from flooding, 9 Mha from wind erosion, 6 Mha from salinity, and 7 Mha from a combination of factors. This is extremely serious...

Soil degradation can take many forms, from erosion to salinization to the overall depletion of organic matter. The expression of soil degradation is broad, and so too are the causes. As the world population nears eight billion, and the environmental uncertainty of climate change becomes more...

The low efficiency of feedstock storage and transportation hinders commercialization of a switchgrass-based biofuel industry although the feedstock has various environmental benefits. This study develops a sustainable switchgrass supply chain that balances its economic and environmental...

Soil can be degraded by several natural or human-mediated processes, including wind, water, or tillage erosion, and formation of undesirable physical, chemical, or biological properties due to industrialization or use of inappropriate farming practices. Soil degradation occurs whenever these...

Chaparral shrubland ecosystems are an iconic feature of the California landscape, and a highly biodiverse yet highly flammable backdrop to some of the fastest growing urban areas in the United States. Chaparral-type ecosystems are a common element of all of the world's Mediterranean-type climate...

Deforestation in developing and middle income countries is an urgent global problem, affecting climate change, soil erosion, major river basins, and livelihoods of poor households living near the forests. Public discussions of the problem are frequently dominated by widely held beliefs...

This article is intended as a review of the current situation regarding the impact of olive cultivation in Southern Spain (Andalusia) on soil degradation processes and its progression into yield impacts, due to diminishing soil profile depth and climate change in the sloping areas where it is...

This study sought to determine competency capacity building needs of crop farmers in soil erosion management in Enugu State, Nigeria. Four research questions guided the study. Descriptive survey research design was adopted for this study. The study was carried out in Enugu State. The population...

Soil Mapping and Process Modeling for Sustainable Land Use Managementis the first reference to address the use of soil mapping and modeling for sustainability from both a theoretical and practical perspective. The use of more powerful statistical techniques are increasing the accuracy of maps...

Since humans worldwide obtain more than 99.7% of their food (calories) from the land and less than 0.3% from the oceans and aquatic ecosystems, preserving cropland and maintaining soil fertility should be of the highest importance to human welfare. Soil erosion is one of the most serious threats...

Migration data is matched from the Indian census with climate data to test the hypothesis of climate variability as a push factor for internal migration. The main contribution of the analysis is to introduce relevant meteorological indicators of climate variability, based on the standardized...

The Siwalik Hills is one of the most fragile and vulnerable ecosystems in the Nepalese Himalaya where soil erosion and land degradation issues are fundamental. There is very limited knowledge on soil erosion processes and rates in this region in comparison to other regions of the Himalaya. The...

Concern about soil erosion on arable land in Britain dates back at least 40 years. Monitoring schemes and case studies have subsequently identified the areas at risk, the rates and frequencies and the major factors responsible for erosion. Initial concern focused on impacts on the farm and...

In recent decades, the off-site transport of sediment and nutrients from agricultural land into the neighbouring natural and built environment has become a more pressing environmental sustainability issue than the on-site threats of soil erosion in many of the world’s temperate regions. In the...

Assessing the effects of vegetation on water and soil conversation is the key basis for research and management of ecological restoration on water-eroded areas. In this study, the runoff depth, soil loss and corresponding precipitation of five plots planted respectively with Pueraria lobata,...

This article gives an overview of the general situation and regional differences of rural poverty in China, and points out that in the rural areas of central and western regions with serious soil erosion, the poverty is particularly prominent. Based on previous studies, we take agricultural GDP...

Soil Management (SM) is critical to human well-being that it is more important now because of meeting the high demands for food production and satisfying the needs of an increasing world population. Therefore, the purpose of this descriptivecorrelation study was to investigate the effective...

This document discusses the impact that global climate change has on food production both globally and in Latin America and the Caribbean. The author discusses environmental issues including extreme temperatures, water scarcity, flooding, and soil erosion. Using available information, this...
