Guazhou County of Gansu Province is a typical ecological fragile area lying in the transition area of desert and oasis.The development of its agricultural economy is highly dependent on natural resources and environment.Contradiction of resources characterized agriculture and the fragile ecological environment has become one of the main barriers to log the impact of local agriculture to achieve sustainable development.Aiming at fragile ecological environment and limiting factors of agricultural sustainable development,thoughts and countermeasures of realizing agricultural sustainable development have been proposed. 展开更多

In the present scenario, environmental writing becomes a social discourse. This is the result of a new, vibrant and growing environmental constituency in societies such as Brazil, India, Thailand and other Third World Countries. The features of environmental writing include a visible concern for social justice, defence of livelihood and the determining part played by women. This new discourse has emerged with a new focus on redefinition of terms like human rights, common good, democracy and CPRs (common property resources). Environmental Writing becomes a powerful discourse when it protests against the increasingly intrusive and interventionist developmental projects, implemented by the government, which in turn assert dominion over indigenous people of the land. There is also a strong emphasis on prudence among the poor as contrasted to the ecological profligacy of the rich. This paper is an attempt to examine the voices of dissent and the accountability of postmodern writers and environmental activists in India regarding environmental issues in India. 展开更多

A comprehensive assessment of climate change vulnerability is imperative for formulating effective adaptation strategies and advancing sustainable development goals.As one of the most climate-vulnerable regions globally,the Pan-Third Pole area lacks transnational vulnerability assessments,which poses a significant obstacle to efficient climate adaptation.This study conducted transnational comparisons based on primary micro-survey data collected uniformly across Nepal,Cambodia,Thailand,and Myanmar,which are all located in the Pan-Third Pole region.Evaluating and comparing the vulnerabilities employed an extended framework of climate change indicators.The findings reveal substantial variations in vulnerability among the countries,with Cambodia exhibiting the highest vulnerability,followed by Thailand,Myanmar,and Nepal in descending order,primarily due to differences in exposure.Household exposure to climate change also varied significantly.Sensitivity scores decreased in the order of Nepal>Cambodia>Thailand>Myanmar,with demographic factors,tap water accessibility,and land being the major contributors and sources of differentiation among the countries.Regarding adaptability,Thailand demonstrated the highest adaptability,with human and financial capital as the key differentiators.The outcomes underscore the need for tailored policy measures addressing the diverse vulnerabilities,including enhancing household disaster prevention and capital protection.Furthermore,targeted international investments are crucial for improving adaptability among smallholders in this unique region. 展开更多
