Analysis of Climate Change Impacts and their Mitigation Strategies on Vegetable Sector in Tropical Islands of Andaman and Nicobar Islands, India

Shrawan Singh and Naresh Kumar Bainsla

The climate change is real phenomena and it will have impact on productivity and livelihood of primary farming options. Tropical Island regions are among the most vulnerable to this climatic catastrophe which affect local production of foods particularly perishable like vegetables. The phenomena will lead to a situation of high temperature-high humidity-low light with excess or deficit moisture. This change will help pest dynamic and buildup of their population but negatively affect the crop plants. Slight changes in crop factors have large impact on crop physiology and reproductive biology, resultantly larger change in their productivity and profitability. The change in climatic factors modifies genotype × environment interaction for physiological and economic traits by plants. Vegetables are succulent herbs which are more prone to both biotic and abiotic stresses. However, large germplasm and wide range of species and genetic diversity in tropical climate provide an opportunity to develop climate resilient genotypes to minimize the impact and assure economic returns to the farmers. The paper proposes breeding strategies for vegetable crops which could help in climate resilient breeding programme.
