Diversification is critical to agro-ecological transitions to ensure food security and nutrition while conserving, protecting and enhancing natural resources. The growing demand for agro-ecological and food security solutions suggest that efforts be made to utilize sustainable agriculture, and agro-ecological methods by utilizing available rural landscapes and communities in an effort to fulfill these demands. Surveys of sustainable agriculture, organic farmers and agro-ecological interests were conducted in the impoverished region of North-East Trinidad. Survey results reported over 180 farmers with >1 - 10 acres of available farmland supported a high agricultural production capacity. The highest average per capita for vegetables was tomato (2.3 acres), for tubers was yam (1.03 acres), and for tree crops was green fig (900 plants). Livestock production was limited with duck production being highest (165). There is an increasing earning potential for small farmers and leaseholders, from utilization of non-traditional export crops and expanding agro-ecological land usage, increasing sustainable agriculture production in the area.展开更多

It results from the death of dopaminergic neurons. The pathophysiological mechanisms in idiopathic PD include the production of α-synuclein and mitochondrial respiratory function-affecting complex I, caused by reactive oxygen species.Therefore, the use of natural antioxidants in PD may provide an alternative therapy that prevents oxidative stress and reduces disease progression. In this review, the effects of hydroxytyrosol, Ginkgo biloba,Withania somnifera, curcumin, green tea, and Hypericum perforatum in PD animal and cell line models are compared and discussed. The reviewed antioxidants show evidence of protecting neural cells from oxidative stress in animal and cell models of PD. However, the clinical efficacy of these phytochemicals needs to be optimised and further investigated.展开更多
