Research on the Sustainability of Afghanistan Based on the Emergy Analysis

With outstanding geographical location and rich natural resources, coastal cities have become concentrated and active areas of human social and economic production. Furthermore, a large number of human activities have posed a great deal of ecological environmental pressure to coastal ecological areas. The emergy analysis method is selected to construct an index system with a total of nine indicators at five levels, including emergy source structure, social subsystem, economic subsystem, environmental subsystem, and comprehensive evaluation of sustainable development. The development level of subsystems and the sustainable development ability of ecosystem in Shenzhen, Dalian, Ningbo, Qingdao, and Xiamen were evaluated. The emergy sustainable index of the five cities is 0.10, 0.23, 0.31, 0.49, and 0.93, respectively. According to the evaluation results, coastal cities should comprehensively optimize the population structure, reasonably develop natural resources, make efficient use of marine resources, attach importance to the source control of pollutants, and strive to build a modern economy, so as to realize the sustainable development of coastal urban ecosystem.

Afghanistan is ranked fourth of the most vulnerable countries to climate change. Climate change impacts livelihoods, food insecurity, and displacement caused by human induce-activities like deforestation and land pasture degradation. Drought is the major shock affecting 64% of household in 2024. The study provides a comprehensive analysis of the impacts of climate change in Afghanistan and the country’s sustainable development efforts. This was done through an integrative literature review using database like Google Scholar, PubMed, Scopus and Web of Science with a total of 80 articles spanning from 2015 to 2024. The study indicated that sustainable development efforts is impacted by climate change with agricultural sector projected to decline in wheat, rice, and barley (28%, 4.92%, 387kg respectively) by 2050. This not only impacts the country economy but also had an impact of SDG (Goal 1, 2, 3, 6, and 8). The temperature is expected to reach 1.5oC and 3oC by 2050 and rainfall by 25%. Precipitation will decline by 12-25m by 2050. Even though sustainable development efforts have been implement in area of health and agriculture with focus on reducing temperature that affect grain crops, 59.5% of people still experience food insecurity. Reforestation, conservation, and community awareness through community base programs has been enhanced. However, these initiatives are hampered by lack of regulations, government instability, and limited finance. To counter the impacts of climate change in Afghanistan, the study proposed recommendations such as international cooperation, funding for sustainable infrastructure in health, agriculture, and water resource management.
