Item type:Publication, Access status: with files , RUVIVAL Publication Series Volume 5The RUVIVAL Publication Series is a compilation of literature reviews or introductory texts on topics concerned with the revitalisation of rural areas. It is part of the e-learning project RUVIVAL and each of the three contributions in this publication is connected to further interactive multimedia material, which can be reached under http://www.hoou.de. The first paper is an introduction to the global soil status, which in the past decades has continued to deteriorate. Globally, the total area of arable land has decreased, mainly due to unsuitable land usage related to agricultural practices. As a result of these practices, both chemical and physical degradation of soil can occur. An interrelated factor contributing to the loss of arable land is erosion, which is a naturally occurring process, but can be accelerated by human activities. This paper reviews research conducted on the soil situation in the six continents and therefore provides a global overview, including specific causes and soil management and monitoring practices. The second paper is a literature review on soil erosion and explains the mechanisms that cause it, both natural and human-induced. Most commonly, soil erosion is associated with water; however, it can also be caused by wind, especially in arid and semi-arid regions. This paper presents different soil conservation practices from around the world, showing that there is no single principle applicable to all cases. In addition to tailoring soil conservation measures to the specific environment, some local agronomic measures may also prevent erosion and these are also described in the paper. Lastly, the state of the art of soil erosion control measures is presented. The third paper in this volume focuses on rainwater harvesting methods developed from traditional ecological knowledge and indigenous knowledge. These methods are divided into two categories: micro-catchment methods and macro-catchment and floodwater methods. Bamboo drip irrigation and rice-fish farming in India are reviewed as case studies.Publicationtype: Journal Issue955 4836 - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Access status: without files , A Literature Review on Soil Erosion Quantification and Measurements(2019-09); Soil erosion is a geomorphological process caused by nature or human activities. It exists throughout the world and erosion rates are highly variable, depending on climatic and topographic conditions as well as local soil properties. Most commonly, soil erosion is associated with water (rain splash or runoff); however, wind, especially in arid and semi-arid regions can cause erosion, too. Many studies investigate the effects of soil conservation practices in different regions of the world, showing that there is no single principle applicable to all cases. In addition to tailoring soil conservation measures to the specific environment, some local agronomic measures may also prevent erosion. The applica-tion of vegetation cover increases soil moisture and organic matter content. This also improvesinfiltration rates of rainwater. Furthermore, the use of organic mulch proves to protect soil against water erosion and improve its physical properties. Whenever possible, agricultural practices should be combined with soil management strategies. Mechanical measures, such as windbreaks and ter-races, are rather expensive and are regarded as additional erosion prevention, but never as a stand-alone approach. There is a high need for governmental action to improve education about soil conservation and apply stronger policies regarding the sustainable use of land.Publicationtype: Journal Article225 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: without files , Energy Access for Sustainable Rural Development: Literature Review on Distributed Renewable Energy for Rural Electrification in Africa(2019-04); ; Access to electricity is a key mechanism for the improvement of living standards and community ser-vices such as healthcare and education, for the reduction of poverty and enhancement of gender jus-tice. However, in 2016, 14 % of the world’s population still lived without electricity, mostly located in rural areas of economically poor areas. Off-grid and mini-grid systems are summarised under the term ‘distributed energy systems’ or ‘decentralised energy systems’ and provide a fast and cost-efficient method for rural electrification. Applicable technologies include solar photovoltaics, wind power, small hydropower and energy from residual biomass. Those small-scale renewable energy systems offer significant reductions in fossil fuel combustion and entailed emissions of greenhouse gases. This paper reviews distributed renewable energy systems and concentrates on energy services for electricity generation in rural Africa. Whereas political uncertainty and a lack of access to investment capital are major barriers for implementing these services, the systems’ contribution to energy security, their flexibility, affordability, modularity and environmental sustainability are driving forces for their expansion. Investment and payback times are often very much lower than those of large-scale centralised systems with their highly expensive and vulnerable networks.Publicationtype: Journal Article157
