Integrated Food - Energy Systems (IFES)
Our life on Earth depends on a dynamic complex of linkages, synergies and interactions among the processes, components and sub-systems of the atmosphere, hydrosphere, lithosphere and biosphere. The ecological view of sustainability focuses on the stability of biological and physical systems. Of particular importance is the viability of sub-systems that are crucial to the global stability of the overall ecosystem. Protection of biodiversity is a key aspect. Furthermore “natural” ecosystems may be interpreted to include all aspects of the biosphere, including man-made environments like intensive agriculture, cities and industrial estates. The emphasis is on preserving the resilience and dynamic ability of the totality of systems to adapt to change, rather than conservation of some “ideal” static state of the environment. Therefore, expansion of renewable bio-energy will require not only advances in technology, but also tangible economic accounting of their environmental and social benefits, compared to fossil fuels.
The development of sustainable, multi-purpose, integrated biomass conversion systems, is based on highly efficient photosynthesis and microbial processes, generating a number of products including energy resources (biofuels). Such systems have the potential for reducing the adverse impacts of agriculture and forestry, while providing food, fibre, pharmaceuticals and supplementary biofuels, to enhance the requirements for an acceptable standard of living. Energy production via biomass conversion of agricultural wastes reduces the environmental costs of food production systems, and provides economic benefit for the farmer, as well as reducing social impacts. As such, it provides a platform for integrating food and energy production in a sustainable manner...
