How does Sentinel-2 protect India’s biodiversity?
India is home to a diverse range of ecosystems, from the Himalayan mountains to the mangrove forests of the Sundarbans, and from the deserts of Rajasthan to the wetlands of Kerala. These ecosystems support a vast array of plant and animal species, many of which are found nowhere else on Earth. However, India’s biodiversity is facing numerous threats, including climate change, habitat destruction, and pollution. To mitigate these threats, it is essential to monitor and manage India’s ecosystems effectively. Recently, scientists at the Indian Space Research Organisation (ISRO), the Indian Institute of Space Technology (IIST), and Gujarat University have developed a new satellite mapping system, Sentinel-2, which can identify submerged plants with 94% accuracy.
The Sentinel-2 system has been used to monitor 500 of India’s largest wetlands, which are crucial habitats for many plant and animal species. The results of the study are alarming, with nearly 100 lakes, mostly in central and southern India, experiencing a significant decline in vital plant life. This decline is a clear indication of the impact of climate change and human activities on India’s ecosystems. The study highlights the need for urgent climate actions to protect India’s biodiversity.
Wetlands are essential ecosystems that provide numerous benefits, including water filtration, flood control, and habitat creation. They are also important carbon sinks, absorbing and storing carbon dioxide from the atmosphere. However, wetlands are facing numerous threats, including drainage, pollution, and climate change. The loss of plant life in wetlands can have significant consequences, including the loss of biodiversity, decreased water quality, and increased greenhouse gas emissions.
The Sentinel-2 system uses advanced satellite imaging technology to identify and map submerged plants in wetlands. The system can detect changes in plant life over time, allowing scientists to monitor the health of wetlands and identify areas that require conservation efforts. The high accuracy of the Sentinel-2 system, at 94%, makes it a valuable tool for monitoring and managing India’s wetlands.
The study monitored 500 of India’s largest wetlands, which are spread across the country. The results showed that nearly 100 lakes, mostly in central and southern India, are experiencing a significant decline in vital plant life. This decline is likely due to a combination of factors, including climate change, pollution, and human activities such as drainage and land use changes. The study highlights the need for urgent climate actions to protect India’s biodiversity, including the conservation and restoration of wetlands.
The Sentinel-2 system has significant implications for the conservation and management of India’s ecosystems. The system can be used to identify areas that require conservation efforts, monitor the effectiveness of conservation actions, and track changes in ecosystem health over time. The system can also be used to inform policy decisions, providing valuable data and insights to policymakers and conservation managers.
In addition to the Sentinel-2 system, there are several other initiatives underway to protect India’s biodiversity. The Indian government has launched several programs to conserve and restore ecosystems, including the National Wetland Conservation Programme and the National Afforestation Programme. These programs aim to protect and restore India’s ecosystems, including wetlands, forests, and wildlife habitats.
However, despite these efforts, India’s biodiversity continues to face numerous threats. Climate change, habitat destruction, and pollution are all taking a significant toll on India’s ecosystems. To mitigate these threats, it is essential to take urgent action, including reducing greenhouse gas emissions, protecting and restoring habitats, and promoting sustainable land use practices.
In conclusion, the Sentinel-2 system is a valuable tool for protecting India’s biodiversity. The system’s high accuracy and ability to detect changes in plant life over time make it a powerful tool for monitoring and managing India’s ecosystems. The study’s findings, which show a significant decline in vital plant life in nearly 100 lakes, highlight the need for urgent climate actions to protect India’s biodiversity. By combining the Sentinel-2 system with other conservation efforts, India can work towards protecting its diverse range of ecosystems and promoting a sustainable future.
