Understanding Environment Impact Assessment

Understanding Environment Impact Assessment 


Many of us have heard about Environment Impact Assessment. By the definition Environment Impact assessment is the evaluation of the effects likely to arise from a major economic development
significantly affecting the natural and man- made environment. Environment Impact Assessment was first developed in the United states as a result of the national environment policy act, 1969(NEPA), for considering possible impacts prior to a decision making taken on whether or not a proposal should be given approval to proceed. This assessment assesses Physical, Hydrological, Social and Economic Impact of any economic or developmental activity. It also provides measures are to be identified to reduce potential adverse impacts through the identification of possible alternatives sites and processes. 

This is a chart which describes the process of Environmental Impact Assessment:



Importance of Environment Impact Assessment:

Various international conventions like the Convention on Biological Diversity (CBD), the Ramsar Convention and the Convention on the Conservation of Migratory Species of Wild Animals (CMS) recognize impact assessment as an important tool for helping ensure that development is planned and implemented with biodiversity in mind. The CBD requests Parties to apply impact assessment to projects, programmes, plans and policies with a potential negative impact on biodiversity and to prevent the development induced displacement of marginalized and deprived people of the country.

Principles Considered in EIA:

  • Clear mandate and provisions.
  • Explicit goals and objectives.
  • Uniform, consistent application.
  • Appropriate level of assessment.
  • Relevant scope of consideration.
  • Flexible and problem solving approach.
  • Open, facilitative procedures.
  • Necessary support and guidance.
  • “Best practice” standards.
  • Efficient, predictable implementation.
  • Decision oriented.
  • Related to condition setting.
  • Follow-up and feedback inbuilt mechanisms.
  • Cost-effective outcomes.

EIA in India:

The Ministry of Environment and Forests (MoEF) of India has been in a great effort in Environmental Impact Assessment in India. The main laws in action are the Water Act(1974), the Indian Wildlife (Protection) Act (1972), the Air (Prevention and Control of Pollution) Act (1981) and the Environment (Protection) Act (1986),Biological Diversity Act(2002). The responsible body for this is the Central Pollution Control Board. Environmental Impact Assessment (EIA) studies need a significant amount of primary and secondary environmental data. Primary data are those collected in the field to define the status of the environment (like air quality data, water quality data etc.)

Secondary data are those collected over the years that can be used to understand the existing environmental scenario of the study area. . Ideally, the primary data must be considered along with the secondary data for complete understanding of the existing environmental status of the area. In many EIA studies, the secondary data needs could be as high as 80% of the total data requirement. EIC is the repository of one stop secondary data source for environmental impact assessment in India.

EIA Process in India

Once an application has been submitted by a project authority along with all the requisite documents specified in the EIA Notification, it is scrutinised by the technical staff of the Ministry of Environment and Forest prior to placing it before the Environmental Appraisal Committees. The Appraisal Committees evaluate the impact of the project based on the data furnished by the project authorities and if necessary, site visits or on-the-spot assessment of various environmental aspects are also undertaken. Based on such examination, the Committees make recommendations for approval or rejection of the project, which are then processed in the Ministry for approval or rejection.


In case of site specific projects such as Mining, River Valley, Ports and Harbours etc., a two stage clearance procedure has been adopted whereby the project authorities have to obtain site clearance before applying for environmental clearance of their projects. This is to ensure avoiding areas which are ecologically fragile and environmentally sensitive. In case of projects where complete information has been submitted by the project proponents, a decision is taken within 90 days.


Monitoring Mechanism in India:

After considering all the facets of a project, environmental clearance is accorded subject to implementation of the stipulated environmental safeguards. Monitoring of cleared projects is undertaken by the six regional offices of the Ministry functioning at Shillong, Bhubaneshwar, Chandigarh, Bangalore, Lucknow and Bhopal. The primary objective of such a procedure is to ensure adequacy of the suggested safeguards and also to undertake mid-course corrections required, if any. The procedure adopted for monitoring is as follows:
  • Project authorities are required to report every six months on the progress of implementation of the conditions/safeguards stipulated, while according clearance to the project.
  • Field visits of officers and expert teams from the Ministry and/ or its Regional Offices are undertaken to collect and analyse performance data of development projects, so that difficulties encountered are discussed with the proponents with a view to finding solutions.
  • In case of substantial deviations and poor or no response, the matter is taken up with the concerned State Government.
  • Changes in scope of project are identified to check whether review of earlier decision is called for or not


Problems with EIA in India:

  • Lack of timely availability of reliable and authentic environmental data
  • Environment being a multi-disciplinary subject, a multitude of agencies are involved in collection of environmental data
  • Considered mere as a project tool or formality when it comes to urban development projects.
  • In some cases like international trade tax incentives, energy conservation, and agricultural subsidies EIA is overlooked.
  • Project level decisions are many times constrained by existing policies and the range of possible alternatives in the project

  • The environmental impact assessment (EIA) studies are conducted over a short period of time and therefore the understanding of the environmental trends, based on a few months of primary data, has limitations


Environment Impact Assessment is a good tool to analyse the potential impact of development projects on natural and man made environment. The need of hour is to do it sincerely without having any prejudice. It should not be considered mere a formality. 

Hope this information is useful for THE RISING YOUTH OF INDIA. Please rise and play an active role in the development of nation.
Jai Hind.

Location of Nuclear Fuels

Location of Nuclear Fuels



Uranium and Thorium are the two most important mineral which are used to generate nuclear energy. Uranium is very common mineral produced to generate nuclear energy. Uranium is generally found in the crust of the earth. Uranium is a silver white metal in the actinide series in the periodic table. (Wiki says Actinide series encompasses 15 metallic chemical elements with atomic number from 89 to 103. Not important for our discussion)

When it comes to reserves Australia has the highest amount of reserves of Uranium with 31% followed by Kazakhstan 12%, Russia 9%, Canada 9%, Nigeria 8% and South Africa 5%. But when it comes to production of Uranium, Kazakhstan tops with 34% followed by Canada 19%, Australia 11%, Namibia 9%, Nigeria 8% and Russia 7%

Apart from reserves Uranium is also obtained by recycling of Plutonium and used Uranium. It is very easy to obtained Uranium from recycling of Plutonium rather than using used Uranium. Uranium can also be obtained by re-enriching depleted Uranium. Russia is very efficient in re-enriching depleted Uranium.

Thorium is a potential substitute of Uranium. Although it is currently not used as a nuclear fuel, but it has greater potential to become a nuclear fuel in near future. Thorium can not be used directly as a nuclear fuel. Thorium is first converted to a fissile Uranium (U233) by capturing a neutrons in a CANDU reactor (Canada Deuterium Uranium Reactor) . CANDU reactor is specially designed to use Thorium as in generating nuclear energy. 

Thorium is more commonly distributed in the crust of the earth than the Uranium. Although exact knowledge of its distribution is not available but it is believed that the highest amount of reserves are present in Australia, USA, Turkey, India,Venezuela and Brazil.

Indian Scenario :

India has very little amount of Uranium available with it. According to Department of Atomic Energy, current reserve of Uranium is India is around 2 lac tonnes. Highest amount of Uranium reserves are present in Andhra Pradesh followed by Jharkhand and Meghalaya. Production of Uranium is banned in Meghalaya due to social and cultural sentiments of Garo, Khasi and Jayantiya tribes. Some of the prominent reserves are:
Jharkhand:

  • Jaduguda
  • Bhatin
  • Turamdih
  • Bagjata
  • Narwapahar
Andhra:
  • Tumalpalle
  • Koppunuru
  • Sikar
  • Yadgir
  • Gogi
  • Wahkut
One interesting thing is that India has substantial amount of Thorium reserves. Thorium is found in form of Thorium Oxide in Monazite ore. Monazite ore is found in beach and rivers sands. Highest amount of Monazite in  the world is found Pallakad and Kollam districts of Kerala, Vishakhapattanam and Mahanadi Deltas in Odisha. Odisha has the richest reserves of Thorium followed by Andhrapradesh, Tamil Nadu, Kerala, West Bengal and Jharkhand.

Unlike the Coal and Petroleum, Nuclear is a clean and green source of energy. As concerns for global warming are high Nuclear provides an alternative to the conventional sources of energy.

INDIAN GREEN BUILDING COUNCIL

INDIAN GREEN BUILDING COUNCIL


Definition of Green Building:

"A green building is one which uses less water, optimises energy efficiency, conserves natural resources, generates less waste and provides healthier spaces for occupants, as compared to a conventional building."

Vision

To enable a sustainable built environment for all and facilitate India to be one of the global leaders in sustainable built environment by 2025.

Concept of Green Homes

Indian Green Building Council (IGBC) Green Homes is the first rating programme developed in India, exclusively for the residential sector. It is based on accepted energy and environmental principles and strikes a balance between known established practices and emerging concepts. The system is designed to be comprehensive in scope, yet simple in operation. 

Benefits

  • Energy saving 20 to 30%
  • Water Saving 30-50%
  • Enhanced air quality
  • Excellent day lighting
  • Health and Wellbeing of occupants
  • Conservation of scare natural resources

Eligibility

IGBC Green Homes Rating System is a measurement system designed for rating new residential buildings which include construction categories such as 
  • Individual Homes
  • High rise residential apartments
  • Gated Communities
  • Row Houses
  • Existing residential buildings which retrofit and redesigned in accordance with the 
  • IGBC Green Homes criteria
The project team can evaluate all the possible points to apply under the rating system using a suitable checklist. The project can apply for IGBC Green Homes certification if it can meet all mandatory requirements and achieve the minimum required points. 



Concept of Green Building Townships


IGBC continuously works to provide tools that facilitate the adoption of green building practices in India. The development of 'IGBC Green Townships Rating System' is another important step in this direction.

The rating system is designed to address large developments and it is mandatory to include residential development as part of the township. Some typical examples of large scale developments are integrated townships, satellite cities, gated communities, campuses with multiple buildings etc.

Concept of Green Building SEZ


Indian Green Building Council(IGBC) has developed green building rating programmes to cover commercial, residential, factory buildings, etc., Rating programmes would help projects to address all aspects related to environment and is an effective tool to measure the performance of the building/ project.

IGBC along with the Ministry of Commerce and Industry (MoCI) has prepared the Green SEZ guidelines. IGBC has further developed IGBC Green SEZ Rating System as an extension of the Green SEZ guidelines which encourages the projects to exceed the requirements of many codes and standards. IGBC Green SEZ Rating System is a voluntary and consensus based programme. 

The rating system has been developed based on materials and technologies that are presently available. The objective of IGBC Green SEZ is to facilitate the creation of energy efficient, water efficient, healthy, comfortable and environmentally friendly SEZ

The rating system evaluates certain credit points using a prescriptive approach and other credits on a performance based approach. The rating system is evolved so as to be comprehensive and at the same time user-friendly.

Non-Conventional Energy Sources: Where India Stands?

Non-Conventional Energy Sources: Where India Stands?


What is Non-Conventional Sources of Energy?

Non-Conventional Sources of Energy are non-exhaustible and re cyclic in nature. for example Air, Water, Solar and various types of other, which is not the part of fossil  fuel.

India's Potential:

Geographical makeup of India is a result of long geological and physio graphical process. Due to this geographical makeup, we have all types of Non-Conventional energy sources ranging from radio active substances like Thorium and Uranium, Geo thermal sources because of the tectonic plates, wind energy because of the  peninsular location, bio gas because of the large population of cattles in the country, hydro-power electricity because of the mature rivers in deccan parts and young rivers of extra peninsular parts, tidal energy and wave energy. Highest part is of hydro power energy but there is lack of infrastructure. Same in case of Bio-gas but if infrastructure is there, the lack of awareness, that how to collect biogas and methane is persisting. Our country is lacking hard because of the rupee depreciation. So technological and infrastructural development are very poor. All types of solar energy and wind energy are with developed nation, or the export oriented economies like China. We are not in the condition to import and our research and development is very poor and we are spending around only 1% of budget in Non-Conventional energy.

National Policies for non-conventional energy:

To convert potential into reality govt of India in 2008 launched National Action Plan for Climate change, which is not only for energy but also conservation of environment. Two mission under this are National Solar Mission and National Mission for Enhanced Energy Efficiency, are the two critical missions which are working towards converting potential into reality, particularly in tropical areas like Rajsthan, Gujrat, Himalayan Belt(Southern Slope, J&K, Himachal Pradesh, Uttarakhand, Sikkim and Arunachal Pradesh). 
Govt. of India also increasing their collaboration with countries like China and USA, to increase the supply of Photo voltic cell as well as also the Concentrated Solar Technology or Solar Thermal Technology. The recent SAARC summit concluded that the SAARC countries should eliminate energy crisis as quickly as possible.
National Non-Renewable Fund provide by Ministry for Renewable Energy. This ministry is formulated in 2007 and now this ministry is providing all the project which are renewable in nature. for example Biogas plant, Investment in Himachal Pradesh which is having the largest potential for Geo thermal Energy.
National Bio Fuel Policy in which we want to encourage use of those fuels which are bio fuels, 3rd and 4th generation fuels, which are concerned with agriculture residuals as well as algae.
Euro Norms and Bharat Norms to promote utility of renewable energy, to control the pollution level and also encourage cluster bus service that uses biogases which is produced by dung and shells of ground nut.
