Developing countries are particularly affected by the pressing global issue of climate change. It is crucial to look into creative solutions because the problems already facing these countries are worsened by rising temperatures, unpredictable weather patterns, and deteriorating air quality. Experimental climate interventions, such as cloud seeding and technologies for improving air quality, are gaining popularity as viable interventions to lessen the negative impacts of climate change. These technologies are increasingly considered practical solutions to address environmental and socioeconomic issues in countries like India, where monsoons drive agricultural productivity and urban centres struggle with extreme pollution.
What is Cloud Seeding?
The purpose of cloud seeding, a weather modification technique, is to increase rainfall by putting chemicals like sodium chloride or silver iodide into clouds. Increased precipitation is intended to help agriculture and restock water supplies, particularly in regions experiencing water scarcity.
Cloud seeding experiments have been carried out in Tamil Nadu, Karnataka, and Maharashtra, among other Indian states. For example, the Varshadhari project in Karnataka sought to alleviate drought conditions by causing rainfall. Cloud seeding has the potential to stabilise crop yields and guarantee water availability, which is crucial for agriculture in a country like India which is largely dependent on monsoon rains. However, there have been conflicting outcomes. Concerns regarding the cost-effectiveness of this technology exist because although some operations have successfully produced rainfall, others have failed due to unfavourable weather conditions. Small-scale cloud seeding operations can cost anywhere from $200,000 to $300,000. Undeniably, it can be difficult for developing economies to bear this financial burden. Globally, nations like China have advanced cloud seeding by implementing extensive projects to control water resources and lower the risk of natural disasters. Countries like India can learn from these initiatives to broaden and ameliorate their own.
Declining Air Quality in Developing Nations
Air pollution is a serious issue in many developing countries. Cities in India, like Delhi, are often among the most polluted in the world. As a result, creative solutions have been developed, like smog towers, which are massive air purifiers intended to remove airborne particles. Delhi has also considered employing cloud seeding to combat pollution, particularly during the winter months when smog worsens. By producing artificial rain, the method may remove pollutants from the air and enhance its quality. Experts warn that certain weather conditions, like adequate atmospheric moisture, are critical to the effectiveness of cloud seeding for this purpose. According to the World Health Organization (WHO) air quality expert Dr Richard Peltier, these technologies are novel, however, they do not deal with the underlying causes of pollution, which include emissions from industry, vehicles, and crop burning.
Financial and Economic Challenges
For developing countries, the high expense of experimental climate interventions is a major obstacle. Each campaign costs between $200,000 and $300,000, and cloud seeding operations require specialised aircraft that cost $5 to $10 million and chemical agents that cost $25 to $50 per gram. Similarly, smog towers cost approximately $2 million to build and $20,000 to $50,000 for annual maintenance. Balancing these costs is a major challenge for countries with limited resources and conflicting priorities, such as healthcare and education.
Governments can look into several tactics to make these technologies economically feasible.
One solution may be utilising Public-Private Partnerships (PPPs). Projects can be co-financed by sectors like tourism and agriculture that depend on clean water and air. For example, consistent rainfall through cloud seeding would help India's agriculture industry, which accounts for 18% of the country's GDP. Additionally, grants and loans are provided by institutions such as the World Bank, UNEP, and IMF. In the past, India has raised $400 million for climate-related initiatives. Lastly, considerable financial gains are accrued by the $850 billion global carbon market. Significant carbon credits could be earned by a smog tower that removes 1,000 metric tons of CO2 a year. By leveraging partnerships, international funding, and carbon markets, these interventions can become more affordable and impactful for developing nations.
Ethical and Practical Considerations
Despite their potential, these technologies come with drawbacks. Because cloud seeding may inadvertently decrease rainfall in one area while changing weather patterns in another, it presents ethical questions. Smog towers and other air purifiers only deal with pollution in specific locations; they don't address larger systemic problems. The dependence on temporary solutions is a significant additional worry. Smog towers and cloud seeding are two examples of technologies that could divert attention from the more important work of addressing the underlying causes, which includes implementing stronger industrial emissions regulations, upgrading public transit, and switching to cleaner energy sources. Not to mention, most of these interventions depend on imported technology, which can lower self-reliance and raise costs. To solve this, countries like India must spend money on research and development to produce affordable, regionally relevant solutions.
Moving Forward
Although they present encouraging opportunities, experimental climate interventions are not stand-alone fixes. Developing countries ought to take a well-rounded approach that incorporates sustainable policies and cutting-edge technologies. The secret to cutting expenses and customising solutions for regional problems is to invest in local research and development (R&D). For optimal results, policies like cloud seeding and air quality enhancements should complement more comprehensive plans like lowering emissions and embracing renewable energy. To increase effectiveness and acceptance, it is imperative that the community is educated about these technologies and their limitations. Since climate issues transcend national boundaries, regional cooperation is paramount. By sharing resources and knowledge, neighbouring countries can have a bigger impact. When combined, these initiatives produce a coherent plan for combating climate change and promoting creativity and adaptability.
Technologies like cloud seeding and air quality interventions present viable avenues for resilience and adaptation as developing nations like India struggle with climate change. They must, however, be a component of a broader plan that addresses fundamental environmental problems and gives sustainability a top priority. These countries can successfully navigate the complexities of climate challenges while creating a more sustainable future through strategic investments, international cooperation, and community involvement. This area offers researchers and students interested in the nexus of climate science, economics, and technology a fascinating chance to help find practical answers to some of the most important problems of our day.
