Book (series)Mainstreaming biodiversity in forestry 2022
Also available in:
No results found.Forests harbour a large proportion of the Earth’s terrestrial biodiversity, which continues to be lost at an alarming rate. Deforestation is the single most important driver of forest biodiversity loss with 10 million ha of forest converted every year to other land uses, primarily for agriculture. Up to 30 percent of tree species are now threatened with extinction. As a consequence of overexploitation, wildlife populations have also been depleted across vast areas of forest, threatening the survival of many species. Protected areas, which are considered the cornerstone of biodiversity conservation, cover 18 percent of the world’s forests while a much larger 30 percent are designated primarily for the production of timber and non-wood forest products. These and other forests managed for various productive benefits play a critical role in biodiversity conservation and also provide essential ecosystem services, such as securing water supplies, providing recreational space, underpinning human well-being, ameliorating local climate and mitigating climate change. Therefore, the sustainable management of all forests is crucial for biodiversity conservation, and nations have committed to biodiversity mainstreaming under the Convention on Biological Diversity (CBD). Mainstreaming biodiversity in forestry requires prioritizing forest policies, plans, programmes, projects and investments that have a positive impact on biodiversity at the ecosystem, species and genetic levels. In practical terms, this involves the integration of biodiversity concerns into everyday forest management practice, as well as in long-term forest management plans, at various scales. It is a search for optimal outcomes across social, economic and environmental dimensions of sustainable development. This study is a collaboration between FAO and the Center for International Forestry Research (CIFOR), lead centre of the CGIAR research programme on Forests, Trees and Agroforestry (FTA). Illustrated by eight country case-studies, the report reviews progress and outlines the technical and policy tools available for countries and stakeholders, as well as the steps needed, to effectively mainstream biodiversity in forestry. -

Book (series)Consequences of biomanipulation for fish and fisheries 2001
Also available in:
No results found.The main goal of biomanipulation by fish reduction is not a change in the fish community but a change in the aquatic ecosystem. Fish reduction is a method to push the system in another state, usually a shift from algae domination to macrophyte domination. Intensive fish removal is done by one of the following methods: seining (the Netherlands, Germany, UK), trawling (Sweden, Finland), use of rotenone (Norway, USA, Poland) and stocking of piscivorous fish (USA, Germany). If circumstances allow it (reservoir, ponds) draining is combined with seining (the Netherlands, UK, Poland). The intensity and duration of fishing differs per case, but is quite important for the way the system changes. Fishing may be combined with stocking of predatory fish, mainly pike and pikeperch (or walleye)......
