Despite almost a century of research and extension efforts, soil erosion by water, wind and tillage continues to be the greatest threat to soil health and soil ecosystem services in many regions of the world. Our understanding of the physical processes of erosion and the controls on those processes has been firmly established. Nevertheless, some elements remain controversial. It is often these controversial questions that hamper efforts to implement sound erosion control measures in many areas of the world. This book, released in the framework of the Global Symposium on Soil Erosion (15-17 May 2019) reviews the state-of-the-art information related to all topics related to soil erosion.

Soil erosion is a major environmental issue with a worldwide impact and direct and indirect effects on soil productivity and consequently on human survival. Although a natural process, soil erosion has increased significantly due to human intervention, especially in the last centuries, through diverse activities such as intensive agriculture, overgrazing, urban sprawl, deforestation, and industrial and mining activities. Presently, soil erosion and degradation promoted by human action have reached extreme levels, necessitating urgent measures to promote soil conservation and rehabilitation. This book presents perspectives on soil erosion occurring in different parts of the world as well as some successful initiatives and strategies for soil conservation and rehabilitation.

Changing land-use practices and the role of soil biological diversity has been a major focus of soil science research over the past couple of decades—a trend that is likely to continue. The information presented in this book points to a holistic approach to soil management. The first part looks at the land use effects on soil carbon storage, and considers a range of factors including carbon sequestration in soils. The second part of the book presents research investigating the interactions between soil properties, plant species, and the soil biota.

Meeting the food requirements of an ever-increasing population is a pressing challenge for every country around the globe. Soil degradation has a negative impact on food security by reducing the cultivated land areas, while at the same time the world population is predicted to increase to 9.2 billion in 2050. Soil degradation adversely affects soil function and productivity and degraded soils now amount to 6 billion ha worldwide. The major factors are salinization, erosion, depletion of nutrients due to exhaustive agricultural practices and contamination with toxic metal ions and agrochemicals, which reduces the activity of soil microbe. In addition, poor soil management also decreases fertility. As such, measures are required to restore the soil health and productivity: organic matter, beneficial microorganisms and nutrient dynamics can all improve the physical, chemical and biological properties of soil. Understanding the role of soil health restoration and management in sustainability and nutritional security calls for a holistic approach to assess soil functions and examine the contributions of a particular management system within a defined timescale. Further, best management practices in cropping systems are important in ensuring sustainability and food and nutritional security without compromising the soil quality and productivity potential. Rational soil management practices must allow environmentally and economically sustainable yields and restoration of soil health.

This book gathers a selection of peer-reviewed contributions presented and discussed at the successful LANDCON 0905 Conference held at Tara Mountain, Serbia, between May 26-30 2009. In keeping with the title of the Conference, "Land Conservation: Global Change - Challenges for Soil Management", this book analyses and discusses the state of the art and future perspectives of the land. Many of the contributed papers are interconnected with natural, socio-economic and environmental changes worldwide. This book is arranged under eight separate but interconnected headings: LANDCON keynote, Global Change and Soil Degradation, Water Management, Soil Erosion, Sediment Transport and Sedimentation Processes, Erosion and Torrent Control in Environmental Change, Desertification, Socio-Economic and Legal and Institutional Aspects of Soil and Water Conservation, Implementing Global and Regional Projects. The book offers reflections, analysis, facts, new data and suggestions/ recommendations on land issues which are the crucial elements in the functioning of biosphere/environment. Land conservation and erosion control require a site specific approach, the setting up of a persistent institutional activity in the affected river basins - an activity that must be legally based to be effective. In this sense, each region subject to land erosion needs to develop competent teams of experts able to deal with the site-specific problems, and to ensure institutional and legal support for this activity. An important aspect is the multidisciplinary character of the activity. It is essential to organize periodical exchange of information about the experiences of such teams operating in different regions. For the continuity of the ongoing efforts it is essential to educate and train young professionals to take part in the activity. The LANDCON offered an excellent opportunity in these regards and it can be recommended to continue the organization of similar meetings in the future, in different parts of the globe. Public information and education are most important aspects of land management and it is worth to underline the positive experiences reported at the LANDCON which confirmed that in many cases the local population has been most supportive to promote land conservation, and cases were quoted about areas where land erosion has been reduced with the growth of population and its agricultural activity - to the contrast of the general assumption that land erosion increases with the increase of population. Four key opportunities were proposed that may also help the message of land conservation reach a wider audience. First was the proposal for the formation of an Intergovernmental Panel on Land and Soil (1PLS), a little sister for the Intergovernmental Panel on Climate Change that had done so much to influence international policy. Second was the proposal to widen the brief of the UNESCO International Sediment Initiative (ISI) to include wider catchment characteristics and third was the proposal for a Balkan regional coordination group to continue the work begun in Serbia in 2007 on the creation of administrative frameworks for land conservation. Fourth, was the proposal to include a younger scholars forum in every future LANDCON meeting in order to help the development of the next generation of land conservation scientists.

Document from the year 2011 in the subject Agrarian Studies, University of Greenwich, language: English, abstract: It is widely recognised that environmental problems such as soil degradation (erosion and desertification) affects many agricultural lands globally. These problems have caused soil quality decline, crop yield reduction, economic crisis, poverty, unemployment, and rural urban migration. Soil management practices are considered as the most vital and sustainable possible solution to control soil erosion and desertification. This management include use of organic manure, crop rotation, use of cover crop, intercropping, planting shelter belt and afforestation, provision of water ways, good surface drainage system, restoration of rangeland, regeneration and secondary forest, and political changes.
