Agricultural 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 کاملAssessing the impacts of agricultural intensification on biodiversity: a British perspective.
Agricultural intensification is best considered as the level of human appropriation of terrestrial net primary production. The global value is set to increase from 30%, increasing pressures on biodiversity. The pressures can be classified in terms of spatial scale, i.e. land cover, landscape management and crop management. Different lowland agricultural landscapes in Great Britain show differen...
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 کاملAgricultural intensification and biodiversity partitioning in European landscapes comparing plants, carabids, and birds.
Effects of agricultural intensification (AI) on biodiversity are often assessed on the plot scale, although processes determining diversity also operate on larger spatial scales. Here, we analyzed the diversity of vascular plants, carabid beetles, and birds in agricultural landscapes in cereal crop fields at the field (n = 1350), farm (n = 270), and European-region (n = 9) scale. We partitioned...
متن کاملIndigenous Peoples and Biodiversity*
Indigenous people number over 300 million. They are inhabitants of practically each main biome of the earth and especially of the least disturbed terrestrial and aquatic ecosystems of the world. Based on an exhaustive review of recently published data, this chapter stresses the strategic importance of indigenous peoples in the maintenance and conservation of world's biodiversity. Four main link...
