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.

Several attempts have been made since the early years of independence of Tanzania to address land degradation. Policies and strategies were formulated that emphasized on the importance of land conservation in achieving economic growth. However, the context in which the earlier strategies were designed and implemented led to further land degradation. Failure of these interventions was partly because policies which backed them remained sectoral and most of them adopted the top-down approach with very little involvement of communities. The United Nations Conference on Environment and Development (UNCED) of 1992 in Rio de Janeiro created a new chapter in the country by insisting on the importance of sustainable development. The new policies and strategies were formulated with intentions to correct the past mistakes. This paper has assessed the extent to which Tanzania's post-UNCED policies and strategies address the recent challenges of climate change on land degradation as reported by the IPCC in 2007. It involved review of selected policies, strategies and related literature on land degradation and climate change. The National Strategy for Growth and Reduction of Poverty (NSGRP) and two other sectoral strategies were reviewed in addition to the environmental, agricultural and water policies. The study finds that significant short and long-term measures to combat the negative effects of land use practices on the land resource are addressed. However, constant review of the policies and strategies is required to ensure that emerging challenges are addressed as part of the overall efforts to combat impacts of global climate change.

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.

Declining soil fertility due to inadequate farming practices, deforestation and overgrazing are among the primary impediments to increased agricultural productivity in Sub-Saharan Africa. These causal factors, driven by social, economic and political forces, manifest themselves in market, policy and institutional failures, inappropriate technologies and practices. This is also the case in Tanzania where over 90 percent of the population is rural and depends on land resources for its livelihood. This study examines the most significant issues affecting levels of productivity and land quality at the community and village level, where local land users take decisions on cropping and livestock management. The specific objectives of the study were to examine farmers' perceptions, particularly their understanding and interpretation of factors and indicators which they link to soil erosion and fertility decline, the level of degradation of crop and pastureland, and the institutional capacity to implement soil conservation and fertility measures with particular regard to land tenure policies, local organizations and extension service. The investigators also sought to identify the technologies, best practices and indigenous knowledge used by households to control erosion, enhance soil fertility, and increase crop and livestock productivity among smallholders.

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.

This book presents an important discussion on the implementation of sustainable soil management in Africa from a range of governance perspectives. It addresses aspects such as the general challenges in Africa with regard to soil management; the structural deficiencies in legal, organizational and institutional terms; and specific policies at the national level, including land cover policies and persistent organic pollutants. This fourth volume of the International Yearbook of Soil Law and Policy is divided into four parts, the first of which deals with several aspects of the theme “sustainable soil management in Africa.” In turn, the second part covers recent international developments, the third part presents regional and national reports (i.a. Mexico, USA and Germany), and the fourth discusses cross-cutting issues(i.a. on rural-urban interfaces). Given the range of key topics covered, the book offers an indispensible tool for all academics, legislators and policymakers working in this field. The “International Yearbook of Soil Law and Policy” is a book series that discusses central questions in law and politics with regard to the protection and sustainable management of soil and land – at the international, national and regional level.

This study investigates land-use dynamics, agricultural development and constraints, land degradation, and the socio-economic and environmental effects of agricultural processes in central Tanzania. It shows there have been both spatial and temporal changes in land-use patterns in the area. The intensity of agriculture has increased; however environmental concerns are arising, including deforestation and soil erosion. The study concludes that to sustain the livelihoods of the people in the area whilst at the same time maintaining the existing dynamics, there is a need for an integrated approach to managing the available and varied resources, as well as measures to ensure environmentally sound agricultural practices.

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.
