Integrated nutrient management, soil fertility, and sustainable agriculture: current issues and future challenges

The challenge for agriculture over the coming decades will be to meet the world's increasing demand for food in a sustainable way. Declining soil fertility and mismanagement of plant nutrients have made this task more difficult. In this brief, Peter Gruhn, Francesco Goletti, and Montague Yudelman point out that as long as agriculture remains a soil-based industry, major increases in productivity are unlikely to be attained without ensuring that plants have an adequate and balanced supply of nutrients. They call for an Integrated Nutrient Management approach to the management of plant nutrients for maintaining and enhancing soil, where both natural and man-made sources of plant nutrients are used. The key components of this approach are described; the roles and responsibilities of various actors, including farmers and institutions, are delineated; and recommendations for improving the management of plant nutrients and soil fertility are presented.Plant nutrients., Soil fertility., Crops Nutrition., Sustainable agriculture.,

Pest management and food production: looking to the future

In their comprehensive paper, Montague Yudelman, Annu Ratta, and David Nygaard examine the key issues with regard to pest management and food production over the coming decades. They draw attention to the lack of adequate information on the magnitude and impact of pest losses; with out such information, policy makers are handicapped when devising strategies for meeting food needs. The authors address both chemical and nonchemical approaches to pest management, high lighting the importance of biotechnology. There is growing public sentiment against biotechnology but little appreciation as yet of its contributions to alleviating hunger by, among other things, controlling pest losses. The authors also adress the important subject of the roles of different actors in pest management, most notably the private sector. A world with out pests is unrealistic and probably undesirable. However, a world with severely reduced losses of food production to pests is achievable by 2020. This paper shows us how.Food crops Diseases and pests Control., Pests Integrated control.,

Feeding 10 Billion People in 2050: The Key Role of the CGIAR's International Agricultural Research Centers

Report from the US based Action Group on Food Security consisting of Robert O. Blake as Chairman, David E. Bell, Jessica Tuchman Mathews, Robert S. McNamara, and M. Peter McPherson. The report, written principally by Montague Yudelman, stresses the importance of international agricultural research for food security and the need for increased financial support to this research and the CGIAR in particular. It also proposes changes in the management and governance of the CGIAR. Annexes detail the funding gap in CGIAR core programs.Agenda document, CGIAR Mid Term Meeting, May 1994

una mirada hacia el futuro

La oferta de alimentos--especialmente de cereales--en los paises en desarrollo tendra que aumentar alrededor de 70% en el ano 2020 para que la poblaci6n prevista de 6.500 millones de personas de esas naciones goce de seguridad alimentaria. Se preve que casi todo este aumento de la oferta de alimentos provendra de los propios paises en desarrollo. Ellogro de ese aumento proyectado exigira tanto un incremento sostenido de los rendimientos de los principales cereales y legumbres como una reducci6n de las perdidas de cultivos por causa de plagas.Non-PRIFPRI1; 2020DG
