Diversified crop rotations enhance groundwater and economic sustainability of food production

Nonrenewability in Forest Rotations: Implications for Economic and Ecosystem Sustainability

The forest rotations problem has been considered by generations of economists (Fisher, 1930; Boulding, 1966; Samuelson, 1976). Traditionally, the forest resource across all future harvest periods is assumed to grow without memory of past harvest periods. This paper integrates economic theory and intertemporal ecological mechanics, linking current harvest decisions with future forest growth, fin...

Sustainability of crop production from polluted lands

Risk and economic sustainability of crop farming systems

Environmental, social and economic attributes are important for the sustainability of a farming system. Comparing farming systems by considering only expected profitability ignores differences in both sustainability and in the riskiness of system returns. Further, in choosing between farming systems, the ability to survive various risks and shocks and continue in the future is important, i.e., ...

A framework for assessing crop production from rotations

Organic farming systems rely on the management of biological cycles for the provision of nutrients, which are crucial to maximising the production from the system. Rotations based on the use of grass-legume leys are central to the concept of organic farming systems, because they have the potential to support both animal production, and a subsequent, exploitative, arable cropping phase. A major ...

Statistical Evaluation of Sustainability of Selected Crop Production in Nigeria

Sustainable agricultural production is a paramount goal of many developing countries in order to ensure that foods required for the growing population are available in the right quantity and quality. This paper evaluated the extent of sustainability of the Nigerian crop production sector using secondary data from the FAO statistical database. Inferences of sustainability was made with contingen...
