Organic farming system and sustainable management of soil pathogens aim at reducing the use of agricultural chemicals in order to improve ecosystem health. Despite the essential role of microbial communities in agro-ecosystems, we still have limited understanding of the complex response of microbial diversity and composition to organic and conventional farming systems and to alternative methods...

Engineering research and development contributes to the advance of sustainable agriculture both through innovative methods to manage and control processes, and through quantitative understanding of the operation of practical agricultural systems using decision models. This paper describes how an engineering approach, drawing on mathematical models of systems and processes, contributes new metho...

The theory of neoclassical welfare economics largely shaped international and national agricultural policies during the Cold War period. It treated technology as an exogenous factor that could boost agricultural productivity but not necessarily sustainable agriculture. New growth theory, the economic theory of the new knowledge economy, treats technological change as endogenous and argues that ...

A case study comparing extensive, low-yielding smallholder maize production with an intensified, high-yielding production system (‘sustainable intensification’) is used to illustrate potential trade-offs between agricultural product carbon footprints (PCFs) and land use (LU). In the comparative analysis the extensive systems had lower PCFs so the conclusion may be that these systems should be e...

Agricultural systems continuously evolve and are forced to change as a result of a range of global and local driving forces. Agricultural and environmental policies are increasingly designed to contribute to the sustainability of agricultural systems and to enhance contributions of agricultural systems to sustainable development at large. The effectiveness and efficiency of such polices in real...

introduction sustainable agriculture can be more objective than fit into the conceptual framework and it is closely associated with rational behavior. the result of such perspective is that sustainable agriculture is an activity based on rationality. the beginning of the formation of stable rationality requires training to create intellectual flexibility for the farmers in order to acquire know...

This paper argues that the largely unrealized potential of agricultural science and technology (S&T) in promoting growth and poverty reduction in developing countries results from deeply rooted incompatibility among policy environments, institutional arrangements, and micro conditions and behavior in agricultural research and development (R&D). Achieving growth and poverty reduction based on gr...
