No results found.According to FAO's latest estimates, global food production needs to increase by 70 percent by 2050 to feed an additional 2.3 billion people. Projections indicate that about 80 percent of the gains in production will need to come from increased yield growth and cropping intensity on existing farmlands. Nutrient depletion of soils is a key constraint to boosting the productivity of small and marginal farmers in Asia and the Pacific, who are among the most food-insecure. Efficient fertilizer use i s vital to reversing this trend. Most soil fertility depletion is caused when disposable household income is too low for farmers to advance from low-input/low-output farming, resulting in nutrient mining. Serious efforts are required at national and regional levels to develop appropriate policies, technologies and capacities to address this challenge. Policies must ensure that soil fertility is not depleted in low-input systems while also helping to curb overuse of fertilizers that, in some case s, leads to serious damage to ecosystems. As part of FAO's mandate to develop a knowledge base in support of food security and rural livelihoods, the Regional Office for Asia and the Pacific commissioned national studies on fertilizer use in South Asia, which has the largest incidence of food insecurity in the region. The studies aim to identify gaps in prevailing strategies and policies, and make recommendations for improvement. This book contains four case studies from Bangladesh, Nepal, Pakis tan and Sri Lanka, and a chapter on guidelines for fertilizer demand assessment and forecasting. -

No results found.Policy makers as well as scientists have started to acquire an honest appreciation of the possibilities of reducing the wastage of materials which could be profitably utilized for improving or maintaining soil productivity. In addition, the great opportunities offered by making more efficient use of the potentials of biological nitrogen fixation in farming systems are now fully recognized. A number of recommendations and suggested guidelines were made by the various Working Groups during the t wo-week Workshop. These covered: 1- Cropping systems and crop residue management 2- Biological N-fixation 3- Research, training and extension. A central theme much emphasized at the Workshop was the fact that agricultural policy makers, technicians and scientists need to study more closely the basic practices of the small farmers so that proposal for the introduction of new systems could be easily understood, integrated and accepted by these farmers.
