Preserving mangrove forests, such as the vast Sundarbans, poses challenges due to the dense vegetation and presence of wild animals. Vishal Jaiswal, a drone pilot, mapped a portion of the Sundarbans to aid in conservation efforts. Mangroves worldwide are at risk due to factors like deforestation, pollution, and climate change, with over half of them facing collapse by 2050.
While some Indian mangroves, like the Sundarbans, are not classified as endangered, signs of stress from human activities and natural causes are evident. Dr. Sahadev Sharma highlights issues such as deforestation and erosion in the Sundarbans, exacerbated by factors like shrimp farming and development. The difficult terrain and presence of saltwater crocodiles and Bengal tigers make field research challenging for scientists.
To monitor the health of mangrove forests, scientists are turning to technology like drones and rSETs (rod surface elevation tables). These tools help measure factors like mangrove height in relation to sea level, crucial for understanding the impact of rising sea levels on the ecosystem. While these methods are more expensive, they offer greater precision and efficiency compared to traditional techniques.
Communities living in coastal regions that rely on mangroves for survival are recognizing the importance of preserving these ecosystems. Fishermen like Laxman Anna in Andhra Pradesh have seen improvements in their catches after efforts to restore mangroves. By planting saplings and working with NGOs and forest departments, communities are witnessing positive changes in their fishing livelihoods.
In conclusion, the preservation of mangrove forests is vital for biodiversity and the livelihoods of coastal communities. Through the use of technology and community efforts, there is hope for the sustainable conservation of these crucial ecosystems. Continued research and collaboration are essential to protect mangroves from the threats of climate change and human activities.
