Book excerpt: Excerpt from Impact of Land Degradation on Future World Food Production Australia and New Zealand-overgrazing and erosion have desertified a large segment of Australian rangeland. Desertification is minor in New Zealand. Productivity of cultivated lands is expected to increase steadily. Meat production will grow somewhat in New Zealand and stabilize in Australia's arid rangelands but increase in subhumid Queensland and in New South Wales. The highest potential yields should center in eastern and southeastern Australia and on the North Island of New Zealand. Europe-desertification has been reversed in some coun tries, but severely eroded soils persist in parts of Spain, Italy, and Greece. Improved small - farm technology should bolster food production. The greatest potential lies in the broad valleys and flood plains along the Mediterranean coast from France to Greece. North and Central america-desertification will not likely affect crop production in Canada and the humid regions of the United States and Mexico. It will blunt crop production increases in the subhumid and semiarid regions of the United States and Mexico, as well as in the Central American mountains. Virtually all of the best arable land in much of North and Central America is under cultivation. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Download or read book The World Food Situation written by Pierre R. Crosson and published by Routledge. This book was released on 2016-03-17 with total page 171 pages. Available in PDF, EPUB and Kindle. Book excerpt: At the beginning of the 1970’s, global grain reserves were level and food prices were low however as the decade progressed crop production plummeted leading to a food crisis. Originally published in the aftermath in 1977, Crosson and Frederick set out to explore the ability of agricultural output to meet the global food demands of future generations. This study analyses how resources and environmental factors would affect food production in developing countries and the United States until the end of the 21st Century. The environmental impacts of land levels, fertiliser and pesticide use are explored in relation to the challenges of meeting food demands. This title will be of interest to students of environmental studies.
Download or read book Land Quality Agricultural Productivity and Food Security written by Keith Daniel Wiebe and published by Edward Elgar Publishing. This book was released on 2003-01-01 with total page 478 pages. Available in PDF, EPUB and Kindle. Book excerpt: 'Action is needed to fight poverty by sustaining the environment and the use of natural resources. Land Quality, Agricultural Productivity, and Food Security explores a range of factors driving food security. The book offers an assessment to link quality of the available land resources with productivity of land and the ability to ensure food security. It offers a mixture of broad-scale assessments across the globe, with detailed case studies, deepening our understanding of economics and decision-making mechanisms. It is recommended to researchers, as well as actors in the private and public domain, who are keen to improve their understanding of the appropriate actions that ensure food security in the decade to come.' - Floor Brouwer, Agricultural Economics Research Institute (LEI), The Hague, The Netherlands Land quality and land degradation affect agricultural productivity and food security, but quantifying these relationships has been difficult. Data are extremely limited and outcomes are sensitive to the choices that farmers make. The contributors to this book - including soil scientists, geographers, and economists - analyse data on soils, climate, land cover, agricultural inputs and outputs, and a variety of socio-economic factors to provide new insights into three key issues: * the extent to which differences in land quality generate differences in agricultural productivity across countries * how farmers' responses to differences or changes in land quality are influenced by economic, environmental, and institutional factors, and * whether land degradation over time threatens productivity growth and food security at local, regional, and global levels.
Download or read book The Global Environmental Benefits of Land Degradation Control on Agricultural Land written by Stefano Pagiola and published by World Bank Publications. This book was released on 1999-01-01 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the global effects of land degradation, but emphasizes other important levels of land degradation: at the field level, it may result in reduced productivity; at the national level, it may cause flooding, and sedimentation; and, at the global level, it can contribute to climate changes, damaging bio-diversity, and international waters. The effects on climate changes are explored, and the report questions the extent to which land degradation on agricultural land, affects climate change. Does it increase emissions of greenhouse gases? Does it affect land's capacity to serve as a carbon sink? Can appropriate management enhance both land's productivity, and its capacity to store carbon? The carbon cycle in soils is analyzed, indicating land degradation is likely to reduce the ability of soils to serve as carbon sink, and release stored carbon into the atmosphere, and, bio-diversity effects are likely to be adverse. Global benefits of land degradation control, include afforestation, to allow increased carbon sequestration, and provide adequate bio-diversity habitats; and, community-based wildlife management, can provide alternatives to some marginal areas. Although integrating global dimensions into land degradation control projects, may reverse the field level, or national problems it is causing, difficulties and constraints will likely contribute to the failure of these projects.
Download or read book Man Land and Food written by Lester Russell Brown and published by Forgotten Books. This book was released on 2018-09-19 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Man, Land and Food: Looking Ahead at World Food Needs The world food problem is closely associated with a rapidly developing population crisis. The food problem is two dimensional. It is partly a production problem, partly a distribution problem. Food supplies in the developed regions are abundant and steadily rising on a per capita basis. In the less developed regions, supplies are inadequate and although grain output per capita is now rising it is still below prewar. The distribution aspects of the food problem give little evidence of immediate improvement. Population in the less developed regions, now totaling billion, is expected to reach nearly 5 billion by the end of the century. If the expected addition of about 3 billion materializes, the less developed regions will need to develop an additional food production capacity equal to current world capacity. Land, the most important ingredient in the agricultural produc tion mix, is in limited supply. Of the earth's land surface of 33 billion acres, less than 3 billion acres actually produces crops in any given year. Ninety-three percent of this area produces edible crops; 71 percent of the total is used to produce grain. Much of the 7 percent in nonfood crops is planted to fibers, mostly cotton.

Download or read book Impact of Agriculture on Soil Degradation I written by Paulo Pereira and published by Springer Nature. This book was released on 2023-05-11 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first of two volumes that together provide a global overview of the impact of agriculture on soil degradation, tracing the most critical drivers like the use and abuse of agrochemicals, mechanization, overgrazing, irrigation, slash and burn agriculture, and the use of plastics. This book covers the main effects of agriculture practices on soil degradation in several countries from Africa, America, Asia, and Oceania, and it elucidates the impact of chemical agents on soil quality, namely, the use of fertilizers, herbicides, pesticides, soil acidification and microplastics pollution. In these continents, a large number of the population depend on agriculture, which sets an enormous pressure on the ecosystems. Divided into 13 chapters, the book offers authoritative contributions about the fundamental soil degradation problems in countries such as Argentina, Australia, Peru and Bolivia, Brazil, Chile, China, Colombia, India, Israel, Kenya, Mexico, South Africa, the United States of America. As soil degradation issues are often linked with biodiversity loss and poverty, readers will also find in this book an important discussion of the different social, economic, political, and environmental aspects contributing to soil quality and sustainable management. Given the breadth and depth of its coverage, the book offers an invaluable source of information for researchers, students, environmental managers and policymakers alike.

Download or read book Economics of Land Degradation and Improvement A Global Assessment for Sustainable Development written by Ephraim Nkonya and published by Springer. 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.
