Saving the Bengal Delta: Restoring Our Water Commons

Bangladesh is the largest delta in the world, it is criss-crossed by numerous lakes, rivers, oxbow lakes and small streams of canals opening out to the Bay of Bengal. The Bengal civilization has flourished by harnessing the rich biodiversity and the natural abundance that is nourished by the intersection of sweet and salt water sources across Bangladesh. For many millennia our ancestors have preserved this natural flora and fauna of our deltaic ecosystem to generate affluent life and livelihoods. The future of the Bengal delta is dependent on the natural ecosystem balance of its water commons. 

What is the current status of our water commons? Bangladesh had 1274 actively flowing rivers in 1971 but today out of the 700 surviving rivers, most of the rivers are dying. According to Government records there are 57 rivers that have officially recognized boundaries. Even these 57 rivers have faced an onslaught of human interventions.  Our water commons are threatened, by increasing encroachment and pollution from unplanned urbanization, industrialization, unplanned construction of roads and embankments, excessive use of agrochemicals in the agriculture lands and unabated disposal of plastic wastes, The future of Bengal delta along with the life and livelihoods dependent on the deltaic ecosystem is under tremendous threat. How can we rescue our Water Commons? How do we save our Bengal Delta? 

If you love to exercise your knowledge and intellect about protecting our Water Commons, the National Earth Olympiad (NEO) 2023 is coming back for you? This is your chance to challenge your knowledge about our Water Commons and be a part of the 1000+ network of NEO Alumnis. There is also an opportunity to join the International Earth Science Olympiad (IESO) 2023 to represent Bangladesh internationally.

The Journey


Feb 11 – Mar 4, 2023

You must answer 20 MCQ correctly out of 30 to pass this round. You may retake as many times as required until Mar 1, 2023

The online exam will be around one hour long, consisting of approximately 40-50 MCQs.


Mar 8 – 18, 2023

A day-long workshop designed to introduce the participants to inter-connected environmental concerns and debates to instill motivation of becoming problem solvers.


Apr 15, 2023

Divisional toppers will sit for the National Round. Top 30 participants will be selected for the Bangladesh National Team Selection Exam. National round to take place online.

Bangladesh National Team Selection Exam

May 1 – 5, 2023

Top 30 from the National Round will participate in this exam. 8 toppers will go through a rigorous training camp for participating in the International Earth Science Olympiad (IESO).

16th International Earth Science Olympiad

August, 2023

The top 8 will have the opportunity to represent Bangladesh in the 16th International Earth Science Olympiad (IESO).


To do well in NEO, we highly recommend participants read all the materials provided in the resource sections.


School/college students enrolled in classes 8 to 12 or private candidates of equivalent levels are eligible to participate in NEO. If anyone appears on the HSC exam but is not admitted into University, he/she can participate in NEO. However, in case of the International Earth Science Olympiad (IESO), their rules and regulations state that previous medal winners at the IESO cannot participate again and to compete for medals at IESO, you must be under the age of 19 by 01 July of the year of the IESO.

Yes, they can participate. During registration, SSC/HSC candidates who haven’t enrolled in their subsequent institute (college/university) can use the name of the institute (school/college) where they graduated from most recently. For O/A Level Private Candidates, you have to use the name of your examination body or curriculum in the place of institute name (such as: British Council, Edexcel Private Candidate, etc)

The questions for the 1st round are mostly based on the basic earth science knowledge and natural phenomena that we encounter in Bangladesh, and some critical thinking questions relating to the theme of NEO from the respective year; while the national round dives deep into the fundamental understanding of Earth Science. For beginners, the book “High School Earth Science”, or class 9-10 level geography textbook by NCTB could be a handy resource for primary review, but there are other books too that we recommend. Please follow the Syllabus and Preparation Guideline sections thoroughly to understand how to prepare accordingly.

The question will be in English as well as Bengali.

After making through the divisional round, toppers from each division participate in the Green Day Training (GDT). GDT is a specially designed workshop to impart understanding of interconnected environmental issues through interactive games, puzzles, simulations, etc. It also helps young citizens develop their leadership skills and instill motivation to act on tackling the local and global environmental issues. It’s a day-long training which will be held in person, in all 8 divisions of Bangladesh. The overarching goal of the GDT is to create a nationwide network of empowered young citizens who will act as a catalyst to bring about positive socio-economic and environmental change.

IESO is the International Earth Science Olympiad, an annual competition for secondary school students (not older than 19 years during the contest). The students have to test their skills in all major areas of Earth sciences, including geology, meteorology, hydrology, planetary science and environmental sciences. The official language of IESO is English; however, supervisors may translate the written examinations and related materials into the participants’ native language. Selected national winners from NEO get a chance to train for and after a further selection, the top 4 to 8 students get to participate in the IESO.

25-30 toppers of each division will get the opportunity to participate in GDT. Those who successfully complete the GDT, are recognised as a NEO Alumni and receive a certificate of completion. Top 30 winners in the national round also get another certificate.

There is an IESO team selection process right after the national round, which includes a series of theoretical tests, and a few group assessment activities (online or offline). Prior to the assessments, students go through a few discussion/study sessions, mostly online.
