Nexus between Life Expectancy, CO2 Emissions, Economic Development, Water, and Agriculture in Aral Sea Basin: Empirical Assessment
[ad_1]
1. Introduction
With the aforementioned context in mind, this study aimed to establish the relationship between life expectancy at birth and the basic indicators of socioeconomic development. The novelty of the study is to investigate the potential integration of “life expectancy” factors into policies pertaining to carbon dioxide (CO2) emissions and water productivity in Aral Sea basin countries. The objective of the research is to examine the dynamic relationship between life expectancy, environmental degradation, economic development, water, and agriculture. In this regard, we set out to answer the following two research questions: (1) In the Aral Sea region, are CO2 emissions contributing to a diminished life expectancy? (2) Does water scarcity contribute to a reduction in the region’s population’s life expectancy? As far as our understanding extends, there has been no single research that has specifically examined this matter. By providing answers to these two significant questions, the current research aims to provide policy recommendations for long-term sustainable development.
3. Methodology
In Equation (1), the variable “lex” represents life expectancy at birth and serves as an indicator of health status. The variable “co2” represents carbon dioxide emissions. “health” refers to the amount of money spent on the health sector as a proportion of the GDP. “gdp” represents the overall economic growth of a country. “water” refers to water productivity, while “agr” represents the value added in the agriculture sector. “urb” represents the urbanization rate, which is measured by the urban population. “eng” refers to the overall energy consumption, while “re” represents the proportion of renewable energy consumed in relation to the entire amount of energy utilized. “hc” represents the human capital, which is proxied by primary school enrollment percentage (gross).

In the present research, panel data spanning the years 2002 to 2020 has been applied for empirical estimation purposes. The World Development Indicators database maintained by the World Bank provides all of the acquired data.
6. Conclusions
The majority of the existing studies recommend that all Aral Sea basin countries should minimize water pressure, mostly resulting from the agriculture sector. Considering climatic changes and negative environmental changes happening in the deserts of the dried Aral Sea, more green growth strategies should be supported, both financially and technically. The increasing population of the Aral Sea basin can be directed to less water-dependent industries such as tourism, IT, and other soft industries that can generate even more revenue compared with agriculture.
The present research has examined the impact of CO2 emissions, health spending, GDP, water usage, agricultural output, urbanization, renewable and non-renewable energy consumption, and the role of schooling on life expectancy at birth in the Aral Sea region. These outcomes might be related to outdated public infrastructure inherited from the Soviet period and environmental degradation in the Aral Sea basin. This research utilized data from the years 2002 to 2020 and employed various econometric approaches, including FMOLS, DOLS, and Driscoll–Kraay. The outcomes of the study reveal that health spending, GDP, water, agriculture output, energy consumption, and education rate have a positive impact on life expectancy, but CO2 emissions have a negative impact on life expectancy. The most important policy takeaway from this study is the need to develop and implement comprehensive policies that take into account health spending, GDP, water, agricultural output, energy consumption, and education level in order to ensure health status. Furthermore, we advocate several policies in accordance with the results of the research:
Optimize the water management strategy and facilities: Formulate an integrated water management plan to enhance the region’s environmental position while ensuring an appropriate usage of its water resources. Furthermore, the authorities of the region ought to undertake a comprehensive and progressive rebuilding of water management facilities, together with broad adoption of water-saving technology and decreasing sewage, to accelerate progress.
Enhance Healthcare Investment: Authorities have to give precedence to the allocation of supplementary government resources in order to enhance the health system and broaden the availability of medical treatment to all individuals. Authorities have the ability to allocate a greater portion of the national budget to the healthcare industry. Another way to improve healthcare funding is through the establishment or expansion of health insurance schemes, which pool resources like premiums and government payments.
Addressing and reducing CO2 emissions: Elevated levels of CO2 emissions have a detrimental impact on life expectancy. CO2 emissions have the potential to cause air pollution and poison the ecosystem. Individuals may have a range of illnesses pertaining to the cardiovascular and respiratory systems, which might reduce their lifespan, necessitating efforts to mitigate carbon dioxide emissions. Governments endeavor to incorporate ecologically sustainable practices across all sectors to enhance the overall well-being of individuals.
Accelerated economic growth: Increased economic growth positively impacts life expectancy. The presence of economic growth enables the establishment of advanced medical facilities such as state-of-the-art hospitals, complex medical equipment, and the development of effective drugs inside a country. Hence, implementing an effective strategy for promoting economic growth is crucial in order to enhance the life expectancy of individuals.
Strategic urban development: Urban development increases life expectancy. Structured urbanization provides individuals with health-related advantages such as minimal pollution, a lush landscape, fresh water, suitable sanitation facilities, sufficient medical facilities, and efficient medical services. Hence, it is imperative to implement urbanization policies that are both dynamic and health-oriented to guarantee a longer lifespan for individuals.
Enhancing Education: Education has a positive impact on lifespan by promoting greater health consciousness and facilitating the maintenance of a healthy lifestyle. Acquiring knowledge and receiving a comprehensive education empower individuals to comprehend the norms and regulations pertaining to health. Therefore, it is imperative to guarantee high-quality education for everyone to protect long-term sustainability.
Similar to any other study, the present investigation is not exempt from shortcomings. Due to insufficient data, we were unable to incorporate additional factors that influence well-being, such as calorie consumption, healthcare accessibility, lifestyle choices, criminal activity, and bribery levels. It is advised that future study efforts include elements that include greater panel regions.
