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 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.

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.

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.

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.
