CAG report on violation of coastal ecosystem norms-

Recently, the Comptroller and Auditor General (CAG) of India tabled a report in Parliament on whether steps taken by the Union Environment Ministry to conserve India’s coastal ecosystems have been successful.

This latest report contains the observations from an audit of Conservation of Coastal Ecosystems from 2015-20.

Background:

India has a coastline of around 7,516 kilometres and the coastal regions are significant for economic growth.

The regulation of coastal zones is crucial for protecting the country’s coastal environment.

● Coastal Zone Regulation:

The Union government has issued notifications under the Environment Protection Act (1986), to regulate activities along India’s coasts, particularly regarding construction.

The Coastal Regulation Zone Notification (CRZ) 2019 classifies the coastal area into different zones to manage infrastructure activities and regulate them.

CRZ-I:

CRZ-I constitutes ecologically-sensitive areas, such as mangroves, corals/coral reefs, sand dunes, national parks, marine parks, sanctuaries, reserve forests, wildlife habitats, etc.

They are situated between high tide lines and low tide lines. * High tide line - the line of intersection of the land with the water's surface at the maximum height reached by a rising tide. * Low tide line - the line on the land where the lowest tide of water touches during spring tide.

CRZ-II:

It constitutes the developed areas up to the shoreline, which fall within the existing municipal limits.

The development of unauthorised structures is not allowed in this zone.

CRZ-III:

Localities, such as rural areas that are relatively undisturbed and do not fall under the above categories, are included in this zone.

Only specific activities related to agriculture or certain public facilities are permitted under this coastal regulation zone.

CRZ-IV:

The zone constitutes water areas from the low tide line up to territorial limits, including areas of the tidal-influenced water bodies.

Activities such as fishing and other allied services are permitted in this zone.

Implementing Agencies:

National Coastal Zone Management Authority (NCZMA) at the Centre,

State/Union Territory Coastal Zone Management Authorities (SCZMA/UTCZMA) in every coastal State and Union Territory,

District Level Committees (DLCs) in every district that has a coastal stretch.

● Why did the CAG undertake this audit?

The CAG has a constitutional mandate, under Article 151, to investigate and report on publicly funded programmes.

It conducted “pre-audit studies” and found that there were large-scale CRZ violations in the coastal stretches.

Incidences of illegal construction activities (reducing coastal space) and effluent discharges from local bodies, industries and aquaculture farms had been reported by the media and this prompted it to undertake a detailed investigation.

● Key Findings of the Audit report:

The audit pointed out various categories of violations.

For one, the Ministry of Environment, Forest and Climate Change hadn’t notified NCZMA as a permanent body and it was being reconstituted every few years.

In the absence of defined membership, it was functioning as an ad-hoc body.

There were instances of the Expert Appraisal Committees (EACs) not being present during project deliberations.

EAC is a committee of scientific experts and senior bureaucrats who evaluate the feasibility of an infrastructure project and its environmental consequences.

There were instances of the members of the EAC being fewer than half of the total strength during the deliberations.

SCZMA had not been reconstituted in Karnataka and there was delayed reconstitution in the States of Goa, Odisha and West Bengal.

The DLCs of Tamil Nadu lacked participation from local traditional communities. In Andhra Pradesh, DLCs were not even established.

Also, there were instances of projects being approved despite inadequacies in the Environment Impact Assessment reports.

■ What it will take to fulfil India's solar power dream-


By 2030, India is targeting about 500 GW of renewable energy deployment, out of which ~280 GW is expected from solar Photo Voltaic.

This necessitates the deployment of nearly 30 GW of solar capacity every year until 2030.

Current production:

A typical solar PV value chain consists of first fabricating polysilicon ingots which need to be transformed into thin Si wafers that are needed to manufacture the PV mini-modules.

The mini-modules are then assembled into market-ready and field-deployable modules.

India’s current solar module manufacturing capacity is limited to ~15 GW per year.

The demand-supply gap widens as we move up the value chain, for example

India only produces ~3.5 GW of cells currently.

India has no manufacturing capacity for solar wafers and polysilicon ingots.

currently imports 100% of silicon wafers and around 80% of cells even at the current deployment levels.

Also, out of the 15 GW of module manufacturing capacity, only 3-4 GW of modules are technologically competitive and worthy of deployment in grid-based projects.

India remains dependent on import of solar modules for field deployment.

● Current govt policy:

Key initiatives include a 40% duty on the import of modules and 25% duty on the import of cells, and a PLI scheme to support manufacturing capex.

Also, it is mandatory to procure modules only from an approved list of manufacturers (ALMM) for projects that are connected to state/ central government grids; so far, only India-based manufacturers have been approved.

While this will certainly help to motivate industry, the major challenges are related to size and technology.

● Size and technology:

The bigger size has an advantage in terms of silicon cost per wafer, as this effectively means lower loss of silicon during ingot to wafer processing.

Producing more solar power for the same module size means more solar power from the same land area.

Land, the most expensive part of solar projects, is scarce in India and Indian industry has no choice but to move towards newer and superior technologies as part of expansion plans.

● Raw materials supply:

There is a huge gap on the raw material supply chain side as well.

Silicon wafer, the most expensive raw material, is not manufactured in India.

India will have to work on technology tie-ups to make the right grade of silicon for solar cell manufacturing and since >90% of the world’s solar wafer manufacturing currently happens in China, it is not clear how and where India will get the technology.

Other key raw materials such as metallic pastes of silver and aluminium to form the electrical contacts too, are almost 100% imported.

India is more of an assembly hub than a manufacturing one, and in the long term, it would be beneficial to move up the value chain by making components that could drive the price and quality of both cells and modules.

● Conclusion:

Although India is making great progress in the deployment of solar PV modules for power generation, its path to become a manufacturing hub for the same requires more than just putting some tax barriers and commercial incentives in the form of PLI schemes, etc.

It will warrant strong industry-academia collaboration in an innovative manner to start developing home-grown technologies which could, in the short-term, work with the industry to provide them with trained human resource, process learnings, root-cause analysis through right testing and, in the long term, develop India’s own technologies.

High-end technology development requires substantial investment in several clusters which operate in industry-like working and management conditions, appropriate emoluments, and clear deliverables.

Not all the Topics are equally important. Few Topics are more important than others, so more efforts should be put on those topics.
