India

Hello,
The scopes of environmental science is limited at present in India, but it is going to see a plunge in the near future. As you know almost in all sector Environmental Protection is given emphasis, hence Environmental Science graduates have a bigger scope. But as of now the main problem is that the job that should be done by Environmental Post graduates are being done by students of Chemistry, Forestry, Agriculture, Botany etc. This is causing a stiff competition for Environmental Science students. But there are still a lot of areas where Environmental Postgraduates are preferred.
Environmental Consultancy: Many environmental consultancies like RAMKY, ENZEN, etc. Are eager to take environmental engineers as Environmental Science postgraduates have broader knowledge about EIA, Environmental Chemistry, Environmental law etc. Hence, because of their versatility, they are preferred over general Science students.
Environmental NGO: Green Peace, WWF, CSE Delhi etc. are the primary NGOs which hire environmental Science post graduate for multiple jobs ranging from Environmental journalism to programme Managers.
State, National and International Agencies: This includes State SPCB, State EIA, CPCB labs, MOEFCC, CES, UNEP, WHO, UNDP etc. These are the best aspects for Environmental Science. Postgraduates as in these institutes you are directly involved in the decision making process and hence can work directly to help Environment.
Research Lab: Almost all the university and government research organisation has an Environmental Department. These labs need JRF or Project Assistants for various projects. These are most preferable for students who intend to pursue career in Research in Environmental Sciences. NET/GATE eligibility is most preferred.
Government PSUs: NTPC, IOCL, CIL etc. all have environment departments. They prefer M.Sc and M.Tech in Environmental engineering. They also require GATE/NET score but few PSUs also take students from their own entrance exams. Private Industries: Industries like Reliance, Adani Port, Wipro, etc. All have environmental departments and they prefer environmental students as they can be employed in multiple roles. M.Sc. Environmental Science has a promising future. Students need to decide what they want to do exactly and go for internship and trainings in their course breaks. Gaining as much skills as possible from internship is important to get good placements.
