Vishal Jaiswal: From Drone Enthusiast to Environmental Protector - A Story of Mangroves and Drones
Article:
Vishal Jaiswal, a drone enthusiast since childhood, has now turned his passion into a profession at the age of 27. Recently, he embarked on a project to map part of the Sundarbans, the world's largest area of mangroves spanning across India and Bangladesh. This vast expanse of mangrove forests faces threats from climate change and human activities, with more than half of all mangrove ecosystems globally at risk of collapse by 2050.
In India, the status of mangroves is mixed, with some regions classified as "critically endangered". The Sundarbans, home to India's largest population of tigers, is not currently considered endangered, but signs of stress due to both manmade and natural factors have been observed. Dr. Sahadev Sharma, a consultant scientist, highlights the challenges of conducting field research in such difficult terrains, leading to the use of innovative technologies like drones for monitoring mangrove health.
The monitoring process involves installing rSETs (rod surface elevation tables) across mangrove forests to measure the height of mangroves relative to sea level. This data is crucial in understanding the impact of sea-level rise on mangrove ecosystems. While the new Lidar scanning method is more precise, it comes with higher costs compared to traditional techniques.
Local communities dependent on mangroves for their livelihoods are also recognizing the importance of conservation efforts. Fishermen like Laxman Anna in Andhra Pradesh have seen improvements in their catches after initiatives to preserve mangroves. By planting saplings and collaborating with NGOs and forest departments, these communities are witnessing positive changes in their fishing yields and livelihoods.
Analysis:
This article sheds light on the critical role that mangroves play in our ecosystems and the challenges they face due to climate change and human activities. By utilizing innovative technologies like drones and Lidar scanning, researchers and conservationists are able to monitor and protect mangrove forests more effectively. Moreover, the positive impact of community-driven conservation efforts is evident in the improved livelihoods of those reliant on mangroves for sustenance. It is essential for individuals and policymakers to support and engage in initiatives aimed at preserving these vital ecosystems for the well-being of both nature and communities.
