Feasibility Study on Small Scale Food Production Using Off-Grid Photovoltaic Water Pumping System in Coastal Dune

Abstract

Approximately 795 million people in the world suffer from malnutrition and most of the population is living in developing countries and in arid region [1]. Small and family farming are main form of food production in the countries and region with high malnutrition rate, but the limited land use and the lack of access to water and energy resources hinder to enhance the supply of nutrient by sustainable food production. Facing these issues, smallscale food production system with consideration of relationship between food, energy and water supply has been attracting a lot of attention in recent years [2,3]. From this background, this study aims to develop the small-scale food production system which is combined photovoltaic (PV) water pumping system with cultivation of vegetable. Specially, groundwater at seashore in coastal dune is considered as new water resource for food production. The results of demonstration test of PV water pumping system and cultivation of vegetable are reported in this paper. Material and Method
