Impact Of The Domestic Labor Market On Sustainability Of Agriculture In Oman, Hemesiri Bandara Kotagama, Hamam Al-Farsi

Journal of Agricultural and Marine Sciences

Undistorted factor markets are a perquisite for efficient allocation of resources and growth in production. In Oman by 2013, only 16% of households have reported agriculture as the main occupation and 53% have reported nonagricultural government employment as the main occupation. This situation is hypothesized to be related to the labor market; where government legislated higher remuneration in the nonagricultural government sector vis-a-vis agricultural sector, influences Omani farmers to move to nonagricultural employment, causing reduced cultivated area and farm production. The study uses operations research methods to quantify the impact of labor market policies on agricultural employment, farm gross income …

Integrated Aquaculture In Arid Environments, Stephen Goddard, Fatma Saif Al-Abri Apr 2025

Integrated Aquaculture In Arid Environments, Stephen Goddard, Fatma Saif Al-Abri

Journal of Agricultural and Marine Sciences

Around one third of the globe is classified as desert or arid (<200mm rain annually) and most such regions lack food security. Traditional freshwater aquaculture is often a marginal activity and competes with agriculture for limited water resources. Developing technologies offer new opportunities to increase productivity of aquaculture through integration with vegetable production in aquaponic systems and to reduce water requirements through the application of biofloc technology. Aquaponic systems combine aquaculture and hydroponic plant production and are integrated within a re-cycled water system. Fish waste metabolites provide the nutrients for plants grown in soil-less, hydroponic systems. Biofloc farming systems operate with minimum or zero water exchange. Suspended biofloc particles develop in fish tanks under conditions of full aeration and controlled carbon to nitrogen ratios. They comprise algae, bacteria, protozoa and particulate organic matter held in a loose matrix. They provide in-situ treatment of harmful fish metabolites, are protein rich, contain essential fatty acids, vitamins and minerals and supplement the diets of filter-feeding farmed species. The integration of fish culture with vegetable production provides new opportunities for small and medium enterprises. Integrated farms occupy a small footprint, optimise the use of resources and can be built close to population centres. This paper reviews current developments in aquaponics and biofloc technology against the background of food security needs in arid regions.
