    Nigeria

    The Nigerian savanna soils are low in fertility, organic matter and cation exchange capacity. The traditional method of improving the fertility and productivity of soils of the savanna is through natural fallowing which typically takes three to five years. The method is no longer suitable for most farmers because of the rapid growth of population in developing countries and the resulting intensive cultivation of agricultural land. In this study, a short fallow technique was adopted using forage legumes. Selected soil chemical properties were also evaluated.

    Extensive livestock farming systems in the Less Favored Areas (LFA) of the European Union (EU) are under social stress and requirement to adapt their production practices to new economic and social realities. This research argues that a restructuring plan for the cereal-sheep system of Castile-La Mancha may represent economic and ecological synergies. The potential implementation of a technical strategy (integrating cereal and sheep farming and increasing acreage of annual forage legumes) has been tested within a community-based research project carried out over three phases.

    Nigeria

    A major reason given for the decline in per capita food production in Nigeria over the last two to three decades is the gradual decline in land productivity. Available information shows that in southern Nigeria, for example, there was recorded a consistent decline in yield per hectare of major food crops between 1995 and 2000. Evidence from the literature suggests that the main reason for this persistent decline in soil productivity is the perpetuation of unsustainable soil management practices by small food crop farmers that dominate the food production landscape in the country.

    Sri Lanka

    Many attempts, which were aimed at promoting Sustainable Agricultural Systems (SAS) in Sri Lanka failed due to poor acceptance by farmers. This situation still exists in spite of the formidable scientific evidence that supports the physical effectiveness of these systems to solve the respective problems. Factors that lead to poor acceptance of SAS by farmers can be broadly categorized as system specific factors and general factors that affect all systems commonly.
