Book excerpt: Soil erosion has been recognized as one of the biggest problems of agriculture worldwide and even more so in developing countries. This dissertation models the dynamic effects of soil erosion both at the farm level and its off-site cumulative effects on inland wetlands by using optimal control theory. Based on a productivity approach, two empirical procedures are derived from the theoretical model. One procedure relies on a limited data set to estimate the shadow price of soil erosion. The other procedure estimates the off-site impacts of soil erosion on wetland services, specifically flood control, that have been gradually reduced due to sedimentation between 1975 and 2001. These estimates of on-site and off-site impacts of soil erosion are then used to assess the cost of agricultural modernization due to environmental degradation and to establish a baseline for policy analysis. The empirical studies are done in a watershed of about 1.4 million hectares located in the south of CÃ3rdoba, Argentina, where agricultural modernization driven, mainly by market forces, has been gradually moving away from low input to intensive agriculture. This transformation is causing an increase in production but it is also reducing the long-term productivity of agriculture had and degrading wetlands. The results show that agricultural modernization has gradually increased the cost of soil erosion. Between 1986 and 1999, the total cost imposed by agricultural modernization was between $182 and $316 million in real 2000 dollars. Assuming that the historical trend holds, the baseline measured by the net present value loss (at a 6% of discount rate) for the next 30 years will be about $121 million, which includes $81 million lost due to future wetland degradation and $40 million lost due to increasing the soil erosion rate on-site. The results also suggest that loss of wetland services by degradation can be as important as the loss of the wetlands themselves. However, the former is often ignored in the political agenda. Finally, the study concludes that along with agricultural modernization, a policy to control soil erosion and prevent inland wetland degradation should be established.

This book was released on 2015-11-11 with total page 695 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume deals with land degradation, which is occurring in almost all terrestrial biomes and agro-ecologies, in both low and high income countries and is stretching to about 30% of the total global land area. About three billion people reside in these degraded lands. However, the impact of land degradation is especially severe on livelihoods of the poor who heavily depend on natural resources. The annual global cost of land degradation due to land use and cover change (LUCC) and lower cropland and rangeland productivity is estimated to be about 300 billion USD. Sub-Saharan Africa (SSA) accounts for the largest share (22%) of the total global cost of land degradation. Only about 38% of the cost of land degradation due to LUCC - which accounts for 78% of the US$300 billion loss – is borne by land users and the remaining share (62%) is borne by consumers of ecosystem services off the farm. The results in this volume indicate that reversing land degradation trends makes both economic sense, and has multiple social and environmental benefits. On average, one US dollar investment into restoration of degraded land returns five US dollars. The findings of the country case studies call for increased investments into the rehabilitation and restoration of degraded lands, including through such institutional and policy measures as strengthening community participation for sustainable land management, enhancing government effectiveness and rule of law, improving access to markets and rural services, and securing land tenure. The assessment in this volume has been conducted at a time when there is an elevated interest in private land investments and when global efforts to achieve sustainable development objectives have intensified. In this regard, the results of this volume can contribute significantly to the ongoing policy debate and efforts to design strategies for achieving sustainable development goals and related efforts to address land degradation and halt biodiversity loss.

Book excerpt: Healthy soils are essential for sustaining economies and human livelihoods. In spite of this, the key ecosystem services provided by soils have usually been taken for granted and their true value - beyond market value - is being underrated. This pattern of undervaluation of soils is about to change in view of rapidly raising land prices, which is the result of increased shortage of land and raising output prices that drive implicit prices of land (with access to water) upward. Moreover, the value of soil related ecosystems services is being better understood and increasingly valued.It is estimated that about a quarter of global land area is degraded, affecting about 1.5 billion people in all agro-ecologies around the world. Land degradation has its highest toll on the livelihoods and well-being of the poorest households in the rural areas of developing countries. Vicious circles of poverty and land degradation, as well as transmission effects from rural poverty and food insecurity to national economies, critically hamper their development process.Despite the need for preventing and reversing land degradation, the problem has yet to be appropriately addressed. Policy action for sustainable land use is lacking, and a policy framework for action is missing. Key objectives of this Issue Paper and of a proposed related global assessment of the Economics of Land Degradation (ELD) are: first, to raise awareness about the need for and role of an assessment of the economic, social and environmental costs of land degradation; and second, to propose and illustrate a scientific framework to conduct such an assessment, based on the costs of action versus inaction against land degradation. Preliminary findings suggest that the costs of inaction are much higher than the costs of action.

This book was released on 2019-05-16 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
