The Alternatives to Slash and Burn (ASB) consortium was formed in 1992 by a group of concerned national and international research institutions to address the global and local issues associated with this form of agriculture. With contributions from scientists, economists, ecologists, and anthropologists, this book synthesizes the first decade of ASB's work. It assesses the environmental, economic, and social impact of deforestation and the needs of small-scale farmers who rely on slash-and-burn agriculture for their livelihood.

The relationships between soils, microbes and humans are of crucial relevance in the tropics, where plant stress and microbial activity are exacerbated. This volume of Soil Biology presents the living component of tropical soils, showing how it is shaped by environmental conditions and emphasizing its dramatic impact on human survival and well-being. Following an introduction to the specificities of tropical soils and of their microbial communities, the biological aspects of soil management are examined, dealing with land use change, conservation and slash-and-burn agriculture, the restoration of hot deserts, agroforestry and paddy rice cultivation. As they are of particular relevance for tropical agriculture, symbioses of plants and microbes are thoroughly covered, as are the biodegradation of pesticides and health risks associated with wastewater irrigation. Lastly, traditional soil knowledge is discussed as a key to our sustainable presence in this world.

This country case study, part of the Operations Evaluation Department (OED) A Review of the 1991 World Bank Forest Strategy and Its Implementation, evaluates World Bank operations in Cameroon for their consistency with the strategy. The strategic aspects of those operations are judged here on their relevance, effectiveness, efficiency, institutional development, and sustainability. The fundamental objective of the forest policy reform in Cameroon was to establish a transparent, equitable, and sustainable management system for forest resources. The outcome of the reform process was limited, for four reasons. First, the government of Cameroon lacked genuine commitment and the capacity to carry out the reform. Second, key actors in the reform process (particularly foreign logging companies and the parliament) chose to oppose it. Third, partners such as the World Bank failed to devise an implementation strategy compatible with the underlying dynamics of political and socioeconomic changes in Cameroon. Finally, while Cameroon's forest policy is well codified in documents, it is poorly implemented. Although the reforms have led to increased tax revenues and increased the share of GDP attributable to the forest sector, the structural underpinnings of the sector have been little affected. Government agencies in the sector continue to be weak. The international logging companies that dominate the sector continue to have a free hand in the development and use of the forest resources of Cameroon. Local communities were left out of the reform process, despite the declared objective to include them in forest resource management. Overall, the interventions of the Bank inside and outside the forest sector in Cameroon were relevant to its strategic objectives, but they were neither efficacious nor efficient. Because of weak institutional development, the achievements are unlikely to be sustained. The Bank should focus its future reform efforts in Cameroon on the collection and dissemination of relevant and reliable information, working with a larger set of stakeholders, and using more Cameroonian expertise to gain local perspective and build capacity. The success of such an approach hinges on government commitment and the cooperation of other donor countries, including those with timber interests in Cameroon.

Emerging to the forefront of sustainable production and consumption are a promising and rapidly evolving concept known as Voluntary Standard Systems (VSS). They encompass the three pillars of sustainability – social, environmental and economic aspects and consequently they can be considered as a tool, which makes sustainable development visible. Currently, they are becoming a significant element in international trade and in the promotion of sustainable development strategies, especially in the context of globalised markets and supply chains. This volume provides a comprehensive overview of the current VSS concepts: from their nature and functioning, to the future outlook for their development. It places VSS in the broader context of global development issues and challenges, including development policy and international sustainability commitments, progress towards achieving ‘green economy’ and meeting climate protection targets. The volume contains also a representative selection of case studies which demonstrate their wide range of application in different sectors of the economy.

Although the main focus of this book is on the estuaries, its scope goes well beyond this particular coastal feature. Indeed, the estuary can only be considered as part of the life cycle of the entire river and the marine area it feeds into: an area particularly subject to human and natural pressures. The main estuaries and deltas of West and Central Africa region provide a variety of goods and services to its coastal population. The most important of them are related to critical fish habitat, wood and charcoal from mangroves, as well as space for agriculture, aquaculture, urban development, tourism and transport. Particular emphasis has been made in this book on mangroves that play a significant role in terms of flood control, groundwater replenishment, coastline stabilization and protection against storms. They also retain sediments and nutrients, purify water, and provide critical carbon storage. Such hydrological and ecological functions explain the focus on serving mangrove ecosystems and the nearby communities, which draw significant income from fishing, rice production, tourism, salt extraction and other activities such as harvesting honey and medicinal plants, hence the need for preserving mangrove ecosystems to ensure sustainability of the estuaries and deltas of West and Central Africa region. The book has a foreword by Mr. Achim Steiner, United Nations Under-Secretary General and Executive Director of UNEP who is stating that credible and up-to-date information is essential for the public at large but more specifically for scientists, researchers, managers, decision-makers all working together in order to safeguard, protect and sustainably manage estuaries, deltas and lagoons, and the coastal and ocean waters of Western and Central Africa.

Advances in close-range and remote sensing technologies are driving innovations in forest resource assessments and monitoring on varying scales. Data acquired with airborne and spaceborne platforms provide high(er) spatial resolution, more frequent coverage, and more spectral information. Recent developments in ground-based sensors have advanced 3D measurements, low-cost permanent systems, and community-based monitoring of forests. The UNFCCC REDD+ mechanism has advanced the remote sensing community and the development of forest geospatial products that can be used by countries for the international reporting and national forest monitoring. However, an urgent need remains to better understand the options and limitations of remote and close-range sensing techniques in the field of forest degradation and forest change. Therefore, we invite scientists working on remote sensing technologies, close-range sensing, and field data to contribute to this Special Issue. Topics of interest include: (1) novel remote sensing applications that can meet the needs of forest resource information and REDD+ MRV, (2) case studies of applying remote sensing data for REDD+ MRV, (3) timeseries algorithms and methodologies for forest resource assessment on different spatial scales varying from the tree to the national level, and (4) novel close-range sensing applications that can support sustainable forestry and REDD+ MRV. We particularly welcome submissions on data fusion.
