  • Soil erosion affects a large part of the Earth surface, and it represents one of the most relevant environmental problems worldwide. Intense land degradation processes that destroyed civilizations in the past are still going on at present. Accelerated soil erosion is one of the main soil threats, as the natural balance between soil formation and loss may be seriously compromised, leading to desertification and permanent loss of fertility and protective function. Soil erosion is not only related to agricultural activities and farming practices, but also to land management in general....

  • The book deals with several aspects of soil erosion, focusing on its connection with the agricultural world. Chapters' topics are various, ranging from irrigation practices to soil nutrient, land use changes or tillage methodologies. The book is subdivided into fourteen chapters, sorted in four sections, grouping different facets of the topic: introductive case studies, erosion management in vineyards, soil erosion issue in dry environments, and erosion control practices.

  • As rates of deforestation and land degradation, and losses of biodiversity and ecosystem services, continue to rise globally, the international community is faced with the challenge of finding land use interventions that can mitigate or reduce the impact of these environmental issues. Agroforestry, the integration of trees in farming systems, has the potential for providing rural livelihoods and habitats for species outside formally protected lands, connecting nature reserves, and alleviating resourceuse pressure on conservation areas.

  • Grasslands occur on every continent except Antarctica, and constitute about 34 percent of the global terrestrial carbon stock. Changes in grassland vegetation due to overgrazing, conversion to crop land, desertification, fire, fragmentation, and introduction of non‐native species affect their carbon storage capacity, and may in some cases even lead to grasslands becoming a net source of CO2. For example, they may lose 20 to 50 percent of their soil organic carbon content through cultivation, soil erosion, and land degradation.

  • Changing climate and rainfall patterns are expected to have significant impacts on agricultural productivity, especially in arid and semi‐arid regions that are already marginal for agriculture. Most climate modeling scenarios indicate that the dry lands of West and Central Asia and North Africa, for instance, will be severely affected by droughts and high temperatures in the years to come. This could lead to land degradation and agricultural expansion.

  • Biological invasions are one of the major threats to our native biodiversity. The magnitude of biodiversity losses, land degradation and productivity losses of managed and natural ecosystems due to invasive species is enormous. It has an adverse impact on our efforts to maintain biodiversity and on our conservation programs, and thus could create societal instability.

  • · Namibia is carrying out a phased testing and implementation of the SEEA approach to environmental accounting. It is focused on several key natural resource sectors, and is designed to answer such questions as how to allocate water among competing uses and how land degradation affects the productivity of rangeland. · The Netherlands routinely constructs the "National Accounting Matrix Including Environmental Accounts" (NAMEA), an extended form of the national accounts input/output matrix which tracks pollution emissions by economic sector.

  • Le Trong Trai et al. (2001) argued that with an abundance of heavily degraded land available for rehabilitation, forest management and other land uses, there is considerable potential for cash earning activities in the buffer zone (for example through economic crop plantations). This activity would also reduce the overall pressure on the forest resources in the nature reserve. They also suggested that current arrangements for forest development and management in the bare lands are costly, create social tensions and seem to be unsustainable in the long run.

  • A more developed agricultural sector enhances food security. This holds particularly true for SSA, a region with much agricultural potential yet affected by food crises. Agriculture in this region is often characterized by undercapitalization, low technology, poor market access, and underutilized or degraded land. These factors increase transaction costs that weaken the production and sale of agricultural commodities.

  • • There is need to diversify urban-development activities within the municipality. An outward spread of these development activities and the creation of satellite towns in areas such as Olkaria, Sulmac and Sharlimar would minimise the pressure on the natural environment, land, forests, air and water resources, as well as on the capacities of socio-economic infrastructures such as sewerage and water supply facilities and roads. This will also result in a reduction of land use conflicts, which is a major cause of environmental degradation in any given urban scenario. ...

  • Many critical survival issues are related to uneven development, poverty, and population growth. They all place unprecedented pressures on the planet's lands, waters, forests, and other natural resources, not least in the developing countries. The downward spiral of poverty and environmental degradation is a waste of opportunities and of resources. In particular, it is a waste of human resources. These links between poverty, inequality, and environmental degradation formed a major theme in our analysis and recommendations.
