Agroforestry and Biodiversity Conservation in Tropical Landscapes
Agroforestry -- the practice of integrating trees and other large woody perennials on farms and throughout the agricultural landscape -- is increasingly recognized as a useful and promising strategy that diversifies production for greater social, economic, and environmental benefits. Agroforestry and BiodiversityConservation in Tropical Landscapes brings together 46 scientists and practitioners from 13 countries with decades of field experience in tropical regions to explore how agroforestry practices can help promote biodiversity conservation in human-dominated landscapes, to synthesize the current state of knowledge in the field, and to identify areas where further research is needed. Agro...
Transitioning to Sustainable Life on Land
Sustainable Life on Land, the fifteenth UN Sustainable Development Goal (SDG 15), calls for the protection, restoration and promotion of the sustainable use of terrestrial ecosystems. Among others, it requires societies to sustainably manage forests, halt and reverse land degradation, combat desertification, and halt biodiversity loss. Despite the fact that protection of terrestrial ecosystems is on the rise worldwide and forest loss has slowed, the recent IPBES report concluded that “nature is declining globally at rates unprecedented in human history”. Consequently, the United Nations General Assembly recently declared 2021–2030 the UN Decade on Ecosystem Restoration. There is no dou...
Fighting Poverty in Sub-Saharan Africa: The Multiple Roles of Legumes in Integrated Soil Fertility Management
Legumes play an important role in the cropping systems of sub Saharan Africa (SSA). Legumes are an important source of nutrition to both humans and livestock by providing the much needed protein, minerals, fibre and vitamins. The sale of legumes seed, leaves and fibre generates income for the marginalized communities especially women. Cultivation of legumes is essential for the regeneration of nutrient-deficient soils. By biologically fixing nitrogen (BNF) in the soil, legumes provide a relatively low-cost method of replacing otherwise expensive inorganic nitrogen in the soil. This enhances soil fertility and boosts subsequent cereal crop yields. Production of legumes in SSA is however; hampered by a number of constraints among them low and declining soil fertility, low soil pH, high salinity, drought and flooding, poor access to improved germplasm, diseases, pests and weeds. Farmers need to learn how to overcome these constraints if the full benefits of legumes are to be gained. This book presents a synthesis of research work on legumes and draws attention to the importance of legumes in integrated soil fertility management (ISFM) and poverty alleviation in SSA.
Protecting Forest and Marine Biodiversity
This timely book contributes to discussions on the best legal practices to use to promote conservation, protection and sustainable use of biological diversity in forest and marine areas. The breadth of issues explored across these two themes is immense, and the book identifies both key differences, and striking commonalities between them.
Saving Forests, Protecting People?
Tropical forest conservation is attracting widespread public interest and helping to shape the ways in which environmental scientists and other groups approach global environmental issues. Schelhas and Pfeffer show that globally-driven forest conservation efforts have had different results in different places, ranging from violent protest to the discovery of common ground among conservation programs and the various interests of local peoples. The authors examine the connections between local values, material needs, and environmental management regimes. Saving Forests, Protecting People? explores that difficult terrain where culture, the environment, and social policies meet.
Conservation of Tropical Rainforests
This book critically engages with how the conservation of tropical rainforests is financed. Beginning with the context of tropical deforestation, alongside an overview of tropical ecology, global environmental policy and finance, the book reviews several conservation financing instruments. These include ecotourism and private reserves, debt-for-nature swaps and government domestic budgetary expenditures for state and national parks. Tropical deforestation and forest degradation are serious global environmental issues, contributing to global climate change, species extinction, and threatening the livelihoods of forest-dependent communities. Yet, many leading companies, individuals and governments are making a positive impact on tropical forest conservation to mitigate greenhouse gas emissions through the use of conservation finance. Conservation of Tropical Rainforests tells the history of international conservation finance and provides a variety of options for individuals, businesses, and governments to support conservation financing projects.
Lessons learned from Long-term Soil Fertility Management Experiments in Africa
This book elucidates the importance of long-term experiments in revealing evidence of soil fertility decline in Africa. An evaluation of experiences from on-going long-term experiments is given in broad detail. The first chapter explains the paradigm shift in soil fertility management then provides justification for long-term experiments before illuminating experiences from long-term experiments in East, West and Southern Africa. The second, sixth, eighth and ninth chapters give an in-depth account of crop management practices and soil fertility interventions in long-term trials within specific agro-ecological zones in West Africa. The rest of the chapters (chapter three, four, five and seven) address crop management, tillage practices and, organic and inorganic fertilizer applications in the context of long-term experiments in specific agro-ecological zones in East Africa.
