It carries particular importance for developing economies. This study intends to verify the relative status of SLS of the 30 districts in Odisha, which is a backward state in eastern India. In this study, a total of 22 relevant indicators relating to the three components of SLS—ecological security, social equity, and economic efficiency have been taken, based on various kinds of government reports. The principal component analysis(PCA) was used to ascertain the indicators and the importance of each of them to the corresponding component of SLS. The ecological security index(ESI), social equity index(SEI), economic efficiency index(EEI), and composite sustainable livelihood security index(CSLSI) of each district of Odisha were calculated through the min-max normalization technique. The results revealed that there are wide variations in SLS among the districts of Odisha. In this study, the districts are categorized into four levels based on the scores of ESI, SEI, EEI, and CSLSI as very low(<0.400), low(0.400–0.549), medium(0.550–0.700), and high(>0.700). According to the classification result of CSLSI, 2 districts are found to be in the very low category, 20 districts are under the low sustainability category, 8 districts are in the medium category, and none of the districts are found to be in the high sustainability category. The district of Sambalpur ranks the highest with a CSLSI score of 0.624. The bottom five districts are Gajapati, Bolangir, Nabarangpur, Kandhamal, and Malkangiri, having the CSLSI scores of 0.438, 0.435, 0.406, 0.391, and 0.344, respectively. The result of this study suggests that region-specific, systematic, and proactive approaches are desirable for balanced development in Odisha. Further, policy intervention is required to implement more inclusive tribal welfare policies.展开更多

Citrus-based agriculture is the principal economic activity in the agricultural sector of the state of Veracruz. It is practiced in mono-crop plantations by the majority of farmers, who are rendered vulnerable to price depreciation resulting from simultaneous harvest and over-supply of a single commodity. Some farmers have associated multiple crops in citrus farms （agroforestry techniques） as a strategy to improve their livelihoods. Farmers who increased agrobiodiversity in their farms have significantly improved their livelihoods compared to mono-crop plantation owners. The research shows that increased agro-biodiversity can be a strategy to improve the livelihoods of citrus producers in the state of Veracruz, with significant economic benefits depending on the crop combination： maize-citrus is the least economically profitable combination （providing 21% in terms of internal rate of return）, while pineapple-citrus, banana-citrus and vanilla-citrus give higher returns （41%, 44% and 221% respectively）. The citrus-vanilla crop combination also has the highest benefit-cost ratio, relative to citrus monocrop （1.91） as well as the highest net present value （MX$579,635.73）. The choice of crop ultimately depends on the farmer＇s priorities. The associated benefits can be classified in three ways which correspond to the tripartite goal of sustainable development： （i） ecological sustainability （through increased ecosystem resilience）, （ii） economic stability （through diversified, less risk-prone sources of income）, and （iii） social well-being （through lower）.展开更多
