Context
The Government of Andhra Pradesh has directed officials to accelerate the implementation of the Great Green Wall of Andhra Pradesh, a project designed to establish a five-kilometre-wide natural barrier along the coastline to prevent coastal erosion and protect against extreme weather events. This initiative, which includes extensive mangrove restoration and afforestation efforts, aims to expand the green wall over 8,888 hectares in the current year, leveraging support from national schemes like and international funding mechanisms like the .
UPSC Perspectives
Environmental
The Great Green Wall project is a prime example of ecosystem-based adaptation (EbA), where natural habitats are restored to build resilience against climate change impacts. The core component of this project is mangrove restoration, supported by the (Mangrove Initiative for Shoreline Habitats & Tangible Incomes) scheme, launched in the 2023-24 Union Budget. Mangroves are critical ecosystems that act as bio-shields; their complex root systems dissipate wave energy, thereby reducing coastal erosion and mitigating the impact of cyclones and storm surges. Furthermore, mangroves are highly efficient at carbon sequestration (capturing and storing atmospheric carbon dioxide), storing up to four times more carbon than terrestrial forests, making them vital for climate change mitigation. The project also incorporates compensatory afforestation (planting trees to replace those lost due to diversion of forest land for non-forest purposes) and the planting of native species and shelterbelts, further enhancing biodiversity and stabilizing the coastal ecosystem. From a UPSC perspective, understanding the ecological services of mangroves and the objectives of the scheme is crucial for GS Paper 3 questions on conservation and climate resilience.
Geographical
Andhra Pradesh has the second-longest coastline in India (after Gujarat), making it highly vulnerable to coastal hazards such as cyclones, sea-level rise, and coastal erosion. The state's geographical location exposes it to frequent cyclonic disturbances in the Bay of Bengal. The Great Green Wall serves as a strategic disaster risk reduction (DRR) mechanism by creating a physical barrier against these extreme weather events. The focus on planting specific species, such as palm plantations and native timber, across different geographical circles (Rajamahendravaram, Guntur, and Visakhapatnam) demonstrates a region-specific approach to coastal zone management. This initiative aligns with the principles of integrated coastal zone management (ICZM), which seeks to balance environmental, economic, and social objectives in coastal areas. For UPSC GS Paper 1 (Geography) and GS Paper 3 (Disaster Management), aspirants should note how geographical vulnerability necessitates large-scale, nature-based interventions like green walls to protect shoreline habitats and human settlements.
Economic
The financing and implementation of the Great Green Wall project highlight the integration of environmental goals with economic development and global climate finance. The project utilizes financial assistance from the (GCF), an international fund established under the to assist developing countries in adaptation and mitigation practices. This demonstrates how states can access international climate finance to fund large-scale conservation projects. Additionally, the project is linked to the , indicating an emphasis on livelihood generation and rural employment through environmental conservation. Planting seven million saplings under this mission provides direct employment opportunities, connecting ecological restoration with poverty alleviation. This dual focus on ecological security and economic opportunity reflects the concept of a green economy. In the UPSC context, questions may explore the economic valuation of ecosystem services provided by mangroves and the mechanisms for financing climate adaptation projects in developing regions.
