Developing middle-range theories linking land use displacement, intensification and transitions MIDLAND

چکیده
Land is a nexus for crucial societal and environmental challenges including food security, access to water, land degradation, biodiversity loss, and climate change. Development of solutions to balance these tradeoffs and synergies is currently hindered by the lack of theories explaining the conditions under which different pathways of land change occur and lead to different outcomes, integrating human and environmental aspects.

Exploring Agricultural Livelihood Transitions with an Agent-Based Virtual Laboratory: Global Forces to Local Decision-Making
Rural populations are undergoing rapid changes in both their livelihoods and land uses, with associated impacts on ecosystems, global biogeochemistry, and climate change. A primary challenge is, thus, to explain these shifts in terms of the actors and processes operating within a variety of land systems in order to understand how land users might respond locally to future changes in broader-sca...
متن کاملGlobal land use change, economic globalization, and the looming land scarcity.
A central challenge for sustainability is how to preserve forest ecosystems and the services that they provide us while enhancing food production. This challenge for developing countries confronts the force of economic globalization, which seeks cropland that is shrinking in availability and triggers deforestation. Four mechanisms-the displacement, rebound, cascade, and remittance effects-that ...
متن کاملAre agricultural land-use models able to predict changes in land-use intensity?
Land-use and land-cover change research needs to pay more attention to processes of land-cover modification, and especially to agricultural land intensification. The objective of this paper is to review the different modelling approaches that have been used in land-use/land-cover change research from the perspective of their utility for the study and prediction of changes in land-use intensific...
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 ...

FAO promotes Sustainable Production Intensification (SPI), which consists of a technology menu for optimizing crop production per unit area, taking into consideration the range of sustainability aspects including potential and/or real social, political, economic and environmental impacts. The author suggests that Genetically Modified Organism (GMO) cropping is not only well aligned to SPI but a...
