DIMAPUR — Teaching had always been Selina Walling’s career aspiration. Viewing it as a respected profession and an avenue for contributing to society, she pursued her academic and professional goals with a clear focus on higher education.
Walling, currently serving as assistant professor in the Department of Environmental Science at Dimapur Government College, completed her schooling at Little Flower School, Kohima, and her higher secondary education at Kohima Science College, Jotsoma. She then pursued undergraduate studies in Biochemistry with Zoology Honours before enrolling for a Master’s degree in Environmental Science at North-Eastern Hill University (NEHU), Shillong.
The decision to specialise in Environmental Science was influenced by a careful assessment of career opportunities. While exploring options after her undergraduate studies, she observed that her earlier field of study was already saturated in Nagaland. Environmental Science, on the other hand, was an emerging discipline with increasing relevance to contemporary environmental challenges. What began as a strategic academic choice developed into a professional interest as she gained a deeper understanding of the field and its significance, particularly in a state where environmental concerns are closely linked to development and livelihoods.
A major milestone in her career came in 2022 when she cleared the Nagaland Public Service Commission (NPSC) Combined Education Services Examination and was appointed assistant professor in Environmental Science. The achievement, according to her, marked the culmination of years of academic preparation.
In this interview with Eastern Mirror, Walling discusses the academic and career opportunities in Environmental Science.
For young readers, how would you explain Environmental Science?
Environmental Science is the branch of science that studies the interactions between the biotic (living) and abiotic (non-living) components of ecosystems, as well as the impact of human activities on the environment. It is an interdisciplinary field that integrates scientific methods and disciplines to understand and address real-world environmental challenges.
Why is Environmental Science becoming increasingly important in today’s world?
With the increasing global concerns about climate change, pollution, loss of biodiversity and the depletion of natural resources, the importance of environmental science has never been more prominent. It provides the knowledge and tools needed to address these challenges and build a sustainable future. It helps in creating awareness and educating people in making effective environmental regulations and management strategies.

What are the major areas or specialisations within Environmental Science that students should know about?
Environmental Science offers a wide range of specialisations, allowing students to pursue careers that match their interests – ecology and biodiversity conservation, climate change studies, pollution control and environmental management, water and waste management, GIS and remote sensing, and environmental policy and sustainability. These fields focus on understanding environmental challenges and developing practical solutions.
What school subjects should students focus on if they want to pursue Environmental Science in the future?
Students should focus on Science subjects, particularly Biology, Chemistry, and Geography, as they provide a strong understanding of natural systems and environmental processes. Developing skills in Mathematics, Computer Applications, and communication can also be highly beneficial for research, data analysis, and problem-solving in the environmental field.
What does a typical Environmental Science degree programme cover?
A typical programme covers ecology, environmental chemistry, environmental physics, biodiversity, pollution studies, climate science, environmental laws, sustainable development, waste management, GIS and remote sensing, research methods and field-based practical work.

Are there any misconceptions students have about studying Environmental Science?
One common misconception among young students about Environmental Science is that it is only offered as a general education or as an elective course. The subject appears familiar and relatable, and, therefore, students think they do not require rigorous academic preparation. While an introductory Environmental Science course may be accessible to students from different backgrounds, the discipline is rigorous and requires critical thinking, scientific literacy and an understanding of complex environmental systems.
Also, another misconception among students about Environmental Science is that it is limited to environmental awareness or tree-planting and social work. In reality, it is a diverse discipline that combines science, technology, policy, and management, offering career opportunities in research, industry, government, consulting, and sustainability sectors.
What opportunities exist within government departments and public sector organisations?
Career opportunities within the government and public sector include roles in environmental management and regulation, pollution monitoring and control, forest and wildlife conservation, urban planning and municipal administration, water resource and watershed management, environmental monitoring and compliance, disaster management, the energy sector, environmental impact assessment, as well as environmental auditing, permitting, and consultancy services
Are there opportunities for students interested in research and academia?
Absolutely. Students can pursue higher studies such as M.Sc., Ph.D. and postdoctoral research. Academic careers include teaching, scientific research, project leadership and contributing to environmental policy and innovation.
What role do technologies such as AI, satellite imaging, GIS, and data analytics play in environmental work today?

Modern technologies have greatly enhanced our ability to understand and manage environmental issues. Tools such as GIS and satellite imaging help monitor land-use changes, forests, water resources, and natural disasters, while AI and data analytics enable environmental scientists to analyse large datasets, predict trends, and support evidence-based decision-making for sustainable resource management
Can Environmental Science graduates become entrepreneurs? What kinds of ventures can they start?
Yes, Environmental Science graduates can become successful entrepreneurs by addressing environmental challenges through innovative solutions. In fact, Environmental Science offers significant entrepreneurial potential, as increasing environmental regulations, sustainability goals and resource management challenges are creating a growing demand for innovative environmental solutions and services. They can establish ventures in areas such as waste management and recycling solutions and services; environmental consultancy; sustainable agriculture – organic farming, vermicompost production, biofertiliser production, and soil testing services; renewable energy; eco-friendly products; water treatment services; and environmental education and awareness programmes. Such enterprises not only generate employment but also contribute to sustainable development.
If you could give one piece of advice to a student considering environmental science as a career, what would it be?
If I could offer one piece of advice, it would be to approach Environmental Science with genuine curiosity and to stay open to interdisciplinary learning, as environmental problems are the most pressing issues of our time, and addressing them requires dedicated, knowledgeable and innovative professionals. Most importantly, be passionate about making a difference. A career in environmental science offers not only diverse professional opportunities but also the satisfaction of contributing to the well-being and the protection of our planet for future generations.
