Available in PDF, EPUB and Kindle. Book excerpt: World Bank Technical Paper No. 370. Local land users and officials often have conflicting perceptions of and responses to land degradation issues. This causes problems for officials in diagnosing and addressing the issue and is a major constraint on the successful implementation of policies and projects to address land degradation. This study looks at the perception and response gap between officials and land users in the diagnosis and remedy of land degradation. It also examines the dynamics of the loss of soil fertility and low productivity at the village level. The study's findings will help shape investment programs to enhance land productivity in Sub-Saharan Africa.

This book was released on 2015-11-11 with total page 686 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.

Available in PDF, EPUB and Kindle. Book excerpt: Traditional methods of land management through rapid change in the name of "development" have led to land degradation. Resettlement during villagisation increased the human and livestock population. The concentration of this increased population into nucleated settlements and the rigid so-called "land-use plans" meant a complete disruption of the traditional land management system. This study points towards the need for educational and awareness programs to go along with policies which have environmental implications.

Download or read book Soil Degradation and Restoration in Africa written by Taylor & Francis Group and published by CRC Press. This book was released on 2021-06-30 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil degradation is a widespread problem in Africa resulting in decreased agricultural productivity while demand for food continues to increase. Degradation is caused by accelerated erosion, acidification, contamination, depletion of soil organic matter and plant nutrients, and salinization. The major cause of soil degradation in Africa is uncontrolled and excessive grazing in the savanna regions followed by deforestation and the use of inappropriate and extractive farming practices. Perpetual neglect of the health of soils in Africa can exacerbate the already serious problems of food and nutritional insecurity and environmental degradation. Food and nutritional security of the growing population of Africa can only be achieved if degraded soils are restored and soils of agroecosystems are managed prudently and sustainably. Ignoring soils and taking the fragile, finite and precious soil resources for granted is the principal cause of poverty, hunger, and environmental degradation. The downward spiral must be reversed through soil restoration measures based on translating science into action. This book describes the soils of Africa, processes of soil degradation, extent and severity of soil degradation, and the impacts of degradation processes on food and nutritional security. Features: Explores the extent and severity of soil degradation in Africa Analyzes the cause-effect relationship between anthropogenic activities and soil degradation Reviews processes of soil degradation in Africa including erosion, salinization, nutrient depletion, and decline of soil organic matter Addresses the effect of climate change on soil degradation in Africa. Explains how soil degradation causes food and nutritional insecurity Part of the Advances in Soil Sciences series, this volume is specifically devoted to the processes and factors that cause soil degradation and the challenges and potential for remediation and restoration of soil health in Africa.

Download or read book Economic Policies for Sustainable Development written by Thomas Sterner and published by Springer Science & Business Media. This book was released on 1994-01-31 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on describing policy instruments in different countries. Its purpose is not only descriptive but also, to some extent, advocatory. We believe that economic instruments can make an important contribution to an environmentally less disruptive path of development. The design of economic instruments is however a fine art and depends among other things on their political acceptability and this acceptability is of course influenced by experience. It is therefore important to provide information on the use of policy instruments in other countries. Policies are currently developing quite fast and thus a book such as this one can inevitably not capture more than a "snapshot" view at a single moment of time. We would hope that the book encourages more experimentation with economic instruments and that countries will make a fuller use of the whole arsenal of economic policy instruments. If the book does succeed in this sense then it will soon become dated as policies change -but that would be a price well worth paying! The book combines a dozen country monographs together with a few international surveys on particular topics (gasoline pricing, vehicle regulations, acid rain, deforestation and global warming). These papers are intended to illustrate the diversity of policy options available. The actual policies adopted depend on economic as well as ecological conditions. The country studies cover two "Western" countries and then concentrate on formerly planned and developing countries. They show that economic instruments are still generally thought of as new and innovative.

Download or read book Precious Forests written by Miodrag Zlatic and published by BoD – Books on Demand. This book was released on 2015-09-30 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forests are the dominant terrestrial ecosystem of Earth. They are distributed across the globe. Forests account for 75% of the gross primary productivity of the Earth's biosphere, and contain 80% of the Earth's plant biomass. Human society and forests influence each other in both positive and negative ways. Forests provide ecosystem services to humans. Forests can also impose costs, affect people's health, and interfere with tourist enjoyment. This publication presents reviews and research results on negative and positive human interference on forests, as well as ecology, management, governance, policy and economic issues. The book consists of four sections with 12 chapters derived from around the world.

Download or read book The Political Economy of Soil Erosion in Developing Countries written by Piers Blaikie and published by Routledge. This book was released on 2016-05-20 with total page 199 pages. Available in PDF, EPUB and Kindle. Book excerpt: First published in 1985. This book examines wide variety of ways in which environmental deterioration, in particular soil erosion, can be viewed and the implicit political judgements that often inform them. Using the context of developing countries, where the effects tend to be more acute due to underdevelopment and climatic factors, this work aims to examine this source of uncertainty and make explicit the underlying assumptions in the debate about soil erosion. It also rejects the notion that soil erosion is a politically neutral issue and argues that conservation requires fundamental social change. This title will be of interest to students of environmental and developmental studies.
Download or read book Multilevel governance carbon management and land use decisions in Tanzania written by Kijazi, M. and published by CIFOR. This book was released on 2017-06-05 with total page 83 pages. Available in PDF, EPUB and Kindle. Book excerpt: Who makes land-use decisions, how are those decisions made, and who influences whom, how and why? This working paper is part of a series based on research studying multilevel decision-making institutions and processes. The series is aimed at providing insight into why efforts to keep forests standing, such as initiatives like Reducing Emissions from Deforestation and Forest Degradation (REDD+), are still so far from altering development trajectories. It underlines the importance of understanding the politics of multilevel governance in forest, land and climate policy and practice, and identifies potential ways forward, while highlighting the role of conservation and sustainable management of forests for the enhancement of forest carbon stocks in developing countries.
Download or read book The context of REDD in Tanzania Drivers agents and institutions written by Demetrius Kweka and published by CIFOR. This book was released on 2015-10-30 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: This country profile for Tanzania provides an overview on the socioeconomic and political context within which REDD+ policies and processes emerge. It explores the Tanzanian REDD+ policy processes and strategies at the national level, identifying barriers, limits and opportunities in national REDD+ arenas to inform future REDD+ design by providing research-based options for achieving efficient, effective and equitable REDD+ (i.e. the 3Es of REDD+). Both direct and indirect drivers of deforestation and forest degradation are at work, including forest conversion to small-scale agriculture, timber extraction driven by demand from national and international markets, fuelwood and charcoal, and population growth. The prospects for REDD+ rest on improving a number of issues: tenure arrangements, forest governance, reliability of long-term funding, benefit-sharing mechanisms, and technical, human and financial capacity. We recommend the continuation of support towards decentralized sustainable forest management and utilization of the participatory forest management model as an entry point for REDD+ initiatives. Participatory land-use planning practices coupled with improved spatial planning and strengthening mechanisms against illegal activities entrenched in driving forest degradation are needed. In addition, for REDD+ to succeed it will need to challenge and overcome the powerful actors invested in and driving the business-as-usual model.
