Agricultural intensification escalates future conservation costs.
The supposition that agricultural intensification results in land sparing for conservation has become central to policy formulations across the tropics. However, underlying assumptions remain uncertain and have been little explored in the context of conservation incentive schemes such as policies for Reducing Emissions from Deforestation and forest Degradation, conservation, sustainable managem...
متن کاملGlobal food security, biodiversity conservation and the future of agricultural intensification
Under the current scenario of rapid human population increase, achieving efficient and productive agricultural land use while conserving biodiversity is a global challenge. There is an ongoing debate whether land for nature and for production should be segregated (land sparing) or integrated on the same land (land sharing, wildlife-friendly farming). While recent studies argue for agricultural ...
متن کاملEstimating the Costs of Conservation in Multiple Output Agricultural Setting
Scarcity of resources for biodiversity conservation gives rise to the need of strategic investment with priorities given to the cost of conservation. While the literature provides abundant methodological options for biodiversity conservation; estimating true cost of conservation remains abstract and simplistic, without recognising dynamic nature of the cost. Some recent works demonstrate the pr...
متن کاملAgricultural intensification and ecosystem properties.
Expansion and intensification of cultivation are among the predominant global changes of this century. Intensification of agriculture by use of high-yielding crop varieties, fertilization,irrigation, and pesticides has contributed substantially to the tremendous increases in food production over the past 50 years. Land conversion and intensification,however, also alter the biotic interactions a...
متن کاملThe agricultural matrix and a future paradigm for conservation.
Land-use policies, especially in tropical zones, are frequently seen as facing three insoluble problems: (1) low or inefficient agricultural production, which leads to (2) clearing of natural habitat for more farmland, which leads to (3) loss of biodiversity (Ausebel 1996; Glokany 1998; Trewavas 2001). The solution to this three-part dilemma is often seen by going backward, so to speak (1) loss...
