A griculture is the dominant sector in the Gambian economy, employing about 70% of the total work force and contributing, on average, 33% of GDP. It produces about 50% of the national food supplies with only about 60% of the country’s total arable land resources currently being utilized. The sector generates approximately 40% foreign exchange earnings and provides two-thirds of total household ...

water shortage crisis is an issue that has led to drastic changes in different agricultural policies, especially in arid and semi-arid areas. uncertainty in the amount of resources, e.g. water, used for agricultural production entails risk for farmers' income and cropping pattern changes. in the present study, the robust optimization model was used for optimal allocation of arable lands of khor...

Agricultural phosphorus (P) use is intricately linked to food security and water quality. Globalization of agricultural systems and changing diets clearly alter these relationships, yet their specific influence on non-renewable P reserves is less certain. We assessed P fertilizer used for production of food crops, livestock and biofuels in the US agricultural system, explicitly comparing the do...

Everglades sediments (wetland soils) near sources of agricultural runoff had low redox potentials, were blackened with sulfide, and displayed high porewater phosphorus (total) concentrations and high water column conductivities. These sediments yielded 10(sup3)- to 10(sup4)-fold-higher numbers of culturable anaerobes, including methanogens, sulfate reducers, and acetate producers, than did sedi...

Efficient use of assets in agriculture is a goal for policy-makers and farmers. Agricultural input resources are scarce therefore optimum use of inputs in different agricultural operations is important. Mathematical programming technique such as data envelopment analysis (DEA) is a well-known approach for estimation efficiency of agricultural DMUs. In this study, efficiency of kidney bean produ...

Investing in research and development spending (R&D) affects total factor productivity (TFP).Recently new theories of economic growth have emphasized the relationship between R&D and TFPand also identified a number of channels through which a country’s R&D affects TFP of its tradepartner. This study seeks to estimate the effect of agricultural R&D and education spending and someother factors on...
