This paper examines the relevance of the current theoretical perspectives in extension for promoting horticultural revolution in developing countries. At present agricultural education and extension occurs within a framework inspired by the green revolution. This paper analyses the inadequacy of this approach from two theoretical perspectives and proposes an alternative framework. It describes ...

In today’s world the driving force of computing has shifted from faster analysis, speedier calculations and solving of more complex problems to achieving energy efficiency, minimization in consumption of electronic equipments, minimization of e-waste and use of non-toxic materials in preparation of electronics. The practice of using computing resources efficiently is gaining serious momentum an...

We summarize the findings of a recently completed study of the productivity impacts of international crop genetic improvement research in developing countries. Over the period 1960 to 2000, international agricultural research centers, in collaboration with national research programs, contributed to the development of "modern varieties" for many crops. These varieties have contributed to large i...

The EU economy is slowing, productivity is waning, and unemployment remains stubbornly high. The question being raised with increasing urgency is how to rekindle “The European Dream.” The EU owes its success to a forward thinking series of economic and social visions that have motivated member states and the citizenry to continue on a common journey: the Maastricht Treaty, creating a political ...

Water is vital to food production: every calorie of plant food requires at least one litre of water, while one calorie of meat or dairy product can require up to 10 litres of water. Water is supplied either through rainfall or through irrigation. Irrigated agriculture uses 18 per cent of agricultural land, and produces 40 per cent of agricultural products. But urbanisation, agricultural land de...

Most of Africa's people live in rural areas and depend on agriculture for their livelihoods. These predominantly small-scale farmers face many challenges, including food insecurity, rising poverty, and natural resource degradation. To increase the productivity, profitability, and sustainability of their farms, they need greater access to affordable yield-enhancing inputs, including well-adapted...

The strategy described in the present paper offers details about the possibility for Brazil to play a more substantial role in the gene revolution. If successfully applied, the powerful science-based technology currently available in Brazil can contribute to extend the benefits of the gene revolution to the poorest countries, very much like the Green Revolution did in the past, thereby reducing...
