The food-biodiversity nexus is a concept that defines and characterizes the complex interactions between agricultural systems and biodiversity conservation. Here we use a social-ecological systems approach that combines fuzzy cognitive mapping and graph theoretic analyses to uncover system properties that determine food security and biodiversity outcomes at a landscape scale.
The Cities Alliance-funded Tenure Security Facility Southern Africa 2012 programme aims to provide specialist tenure technical assistance and advisory services to slum upgrading initiatives in the region. The work also aims to contribute to improved access to land for poorer people, which in turn contributes to improved livelihoods, active citizenship and wealth creation.
Resource-use decisions affect the ecological and human components of the coupled human and natural system (CHANS), but a critique of some frameworks is that they do not address the complexity and tradeoffs within and between the two systems. Land system architecture (LA) was suggested to account for these tradeoffs at multiple levels/scales.
This website contains mainly news reports about the global rush to buy up or lease farmlands abroad as a strategy to secure basic food supplies or simply for profit. Its purpose is to serve as a resource for those monitoring or researching the issue, particularly social activists, non-government organisations and journalists.
In arid regions, oases ecosystems are fragile and sensitive to climate change, and water is the major limiting factor for environmental and socio-economic developments. Understanding the drivers of land use/cover change (LUCC) in arid regions is important for the development of management strategies to improve or prevent environmental deterioration and loss of natural resources.
