Exploring Through Environmental Science Studies

What is Environmental Science?

The study of the environment is not a new thing. From the beginning of time, mankind has studied the environment. However, the branch of science dealing with environment, ie. environmental science, is a modern subject having tracing its origins to the 1960s and 70s, when the world began facing issues like population explosion, pollution etc. Environmental science is an interdisciplinary field integrating various academic disciplines like physics, chemistry, biology, ecology, geology, social science, engineering etc. Environmental science is simply the study of the environment, of solutions to various environmental problems and of the interaction between physical, chemical and biological elements in nature.

It is important for everyone to have a basic minimum knowledge of environmental science, as it helps us to understand the relationship between humans and nature, and how we need to live sustainably in our environment, the need for protecting our environment, different problems affecting our environment etc.

Environmental Science as a Degree:

The usual duration of a Bachelor’s degree in environmental science is 3 years. The eligibility to apply for admission to a degree programme is to have passed a 12th, +2 or pre-graduation examination, with science as core subject, including physics, chemistry and biology.

The duration of a Master’s degree in environmental science is 2 years. The eligibility criterion to apply for this is a bachelor’s degree either in environmental science or in any other science stream, namely geology, geography, biotechnology, microbiology, biochemistry, zoology, botany, fisheries etc.

Admissions for these courses will be merit based (entrance or academic excellence), along with interview.

Course division/ Subjects covered

During the Bachelor’s as well as Master’s courses, one will have to complete a certain number of credits (based on different universities) and it includes core subjects and elective subjects.

Assessment within these courses is done through written exams, viva-voce, laboratory exams, field work reports, seminars, assignments, project work, thesis work and presentations. Credits will be awarded for each, and a student needs to secure a specific number of credits for the completion of the course; the credit requirements vary with different universities/centres.

Higher Studies

· MPhil (1yr/2yr)

Eligibility: MSc in environmental science

Mode of entry: Entrance exam, interview etc

Assessment: Written exams, practicals, projects, thesis writing and presentations, viva-voce.

· PhD (3-5 yrs)

Mode of entry: Entrance, scholarships/fellowships

One needs to find a suitable topic and a guide in a desired institution. Assessment patterns will include coursework, exams, thesis, viva-voce etc.

Research publication in international journals, paper presentations in seminars etc. are other requirements.

· Post-Doctoral Research (PDF)

After completing a PhD, one can join for post-doctoral research. Just like at the PhD level, the researcher needs to select a topic under a suitable guide in concerned universities.

Scholarships:

Various scholarships are available for PhD and post-doctoral researches. These are generally awarded on the basis of merit, academic excellence, gender, caste, religion, physical ability etc. Post-doctoral research scholarships are usually granted based on the relevance of the research topic selected.

A few among the scholarships for PhD and PDF in India are mentioned below:

For PhD:

· CSIR-UGC JRF NET (Exam based)

Job opportunities and Risk Factors:

A few career opportunities in environmental science are as follows: Environmental officer; Waste management officer; Water resource specialist; Climate controller; Researcher (Junior Research Fellow, Senior Research Fellow, Project Assistant, Project associate, Post-doctoral research); Environmental consultant in NGO’s or private firms; Environmental scientist; Hydrologist.

Other streams related to environmental science:

GIS; Climate change; Post graduate diploma in environmental science; Environmental engineering; Environmental law; Disaster management; Eco tourism; Environmental health science

For almost all jobs, an excellent academic performance, publications in journals, work experience etc. are required.

Risk factors:

. Some occupational hazards: The jobs in this sector may involve a lot of travel, extensive field work, working with chemicals, and visiting places with environmental issues.

. Less job opportunities (especially in India)

Future prospects:

At present, there are very limited career opportunities related to environmental science in India. But many developed nations employ environmental scientists/environmental officers in all fields and are more keen on allocating large portions of their national budgets to protecting the environment. As climate change, environmental pollution, water scarcity etc. are increasing at a rapid pace, the need for people to be employed within this field is likely to increase. According to the US Bureau of Labor Statistics, an estimated growth rate of 11% is predicted in environmental science positions between 2016-2026, globally.

Conclusion:

Environmental science is an intrinsic part of our lives. Everyone must have some basic awareness of current environmental issues, and of and how to protect our environment. Even though we may not choose environmental science as a degree or career, we must learn to live sustainably and thus to make life better for our future generations. For those with a pronounced passion in this regard, specializing within this field can be rewarding and exciting.
