Résumé
The sustainability of food production systems is a fundamental issue in a global development context. Its importance is even increased in an area like the Gaza Strip, where natural resources are scarce and extremely exploited and the population density is one of the highest in the world. Furthermore, the United Nations claim that, with respect to the MDGs, the GS is affected by both food insecurity and environmental sustainability. These two aspects are jointly analyzed in this study : in fact, the general goal of this work concerns the sustainability assessment of some existing protein production systems in GS. The adopted methodology consists in the assessment of the WF, of other environmental impacts (using Life Cycle Assessment), and of the proteins production related to some existing agricultural systems, including aquaculture. The main outcomes show that, even though the analyzed systems could quantitatively provide the required amount of proteins, they exploit the groundwater resources in an unsustainable way. Furthermore, aquaculture affects the water consumptions more than other livestock activities, and for this reason, investing on that activity is not convenient. Concerning the Gazians’ diet, the proteins requirement is mainly satisfied thanks to vegetables : this means that, each person would eat a portion of vegetables ten times bigger than the recommended one, assuming the proteins amount recommended by the Food and Agriculture Organization. For this reason, trade mechanisms are suggested to improve the quality of the diet for the population, and to take advantages from virtual water trade. Also the methodology adopted in this study can be evaluated, in light of the results : integrating WF and Life Cycle Assessment (LCA) a complete impacts assessment, considering both local and global perspectives, can be obtained . Moreover, for a better integration of these methodologies, the evaluation of damages to human health, to ecosystem, and to resources, related to water consumption for the arid areas, should be included in the LCA method. Estimating impacts and damages caused by the analyzed agricultural systems, their sustainability referred to natural resources in the GS assessed.
