The Green Revolution has enabled Asian countries to boost their crop production enormously. However, Africa has not benefitted from this agricultural revolution since it did not consider local, but important crops grown in the continent. In addition to their versatile adaptation to extreme environmental conditions, African indigenous crops provide income for subsistence farmers and serve as sta...

We are on the threshold of a truly revolutionary era of discovery—ranging from the origins of the universe to new states of matter and microscopic machines, from a new understanding of the oceans and of the biological connections across the earth's species to the functioning of the human brain and the origins of consciousness. This "golden age" of discovery, with frequent breakthroughs occurrin...

The sustainability of society hinges on the future of agriculture. Though alternatives to unsustainable, high-input industrial agriculture are available, agricultural systems have been slow to transition to them. Much of the resistance to adopting alternative techniques stems from the perceived costs of alternative agriculture, mainly in terms of yields. The general assumption is that agricultu...

The Agricultural Revolution accompanied, either as a cause or as an effect, important changes in human demographic systems. The consensus model is that fertility and mortality increased and health declined with the adoption of agriculture, compared to those for hunter-gatherers. Analysis of the agricultural transition relies primarily on archaeological and paleodemographic data and is thus subj...

An improvement and strengthening of agricultural infrastructure needed to all the levels of supply chain. Shrinking extension is another component of infrastructure that needs attention. After the green revolution in the mid-sixties there has been no major technological innovation, which could give a fresh impetus to agricultural productivity, insufficient extension services and poor access to ...

National agricultural extension and advisory systems have undergone major changes during the past two decades. These changes have been attributed to the success of the Green Revolution, commercialisation of agriculture and trade liberalization. In addition, transnational corporations develop a wide range of new technologies, which directly impact on agricultural production in developed and deve...

This paper employs multiple regression analysis to evaluate the effectiveness of yieldraising techniques available to medieval farm managers (reeves) using a panel dataset of 49 manors held by the Bishop of Winchester from 1349-70. There are three main interesting findings. First, annual weather variation, modelled with climate reconstructions, was highly significant in explaining annual yield ...

Shortly after the agricultural revolution, the domestication of bacteria, yeasts, and molds, played an essential role in enhancing the stability, quality, flavor, and texture of food products. These domestication events were probably the result of human food production practices that entailed the continual recycling of isolated microbial communities in the presence of abundant agricultural food...

This article has evolved from a research project following a micro-level approach to the postwar ‘agricultural revolution’. Above all, it focuses on the diversity of post-1945 agricultural development, i.e. the various ways farming actors experienced, interpreted and acted upon the natural and societal structures of their rural lifeworlds, thereby reproducing and/or transforming the local, regi...
