Book (stand-alone)Organic recycling in Africa. Papers presented at the FAO/SIDA Workshop on the Use of Organic Materials as Fertilizers in Africa, Buea, Cameroon, 5-14 December 1977

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. -
Book (stand-alone)Fertilizer use by crop in the Islamic Republic of Iran 2005Low rainfall and high temperatures in Iran necessitate irrigation and over half the cultivated land is irrigated. Water availability and salinity are major constraints. Iran has long been a major importer of wheat but in 2003 and 2004 domestic wheat production almost satisfied the national demand. Several governmental measures supported production of the crop and favourable rainfall after a drought was also a major factor. Yields of both irrigated and rainfed wheat are low by world standards. Th e intensification of production, in particular through a greater efficiency of fertilization and irrigation, is required in order to achieve a permanent reduction in the country’s dependence on wheat imports, even under less favourable climatic conditions.

Book (stand-alone)A perspective on water control in southern Africa
Support to regional investment initiatives
2003Also available in:
No results found.This discussion paper is a joint production of the FAO Subregional Office for Southern and East Africa and FAO Land and Water Development Division as a response to the regional drought of 2001 and 2002 in the Southern African Development Community (SADC) region. The paper attempts to diagnose the root causes of the failure of food production systems that depend upon the control of water in the all-important root zone. The continuing vulnerability of staple food production systems to periodic drought and the volatility of incomes that are derived from agriculture continue to confound the subregion. Food import bills use up hard-won foreign exchange and distribution logistics to food short areas are stretched to the limit. Turning this chronic vulnerability around, it is argued, will require an advance on two fronts. First, by enhancing profitable farm operations through improved farm management and water control. Second, by expanding the economic opportunities for farmers through pro gressive regulation of the agriculture sector and the associated business frameworks. In this respect, water control is only one (but nevertheless critical) element of the food security equation in the region and it is important to position good water control practice within the broader production environment.
