Climate Change and Environment (CCE)

We provide modern solutions for Climate, Weather and Disaster management

About CCE Unit

IWM has been working with climate projections and scenarios for different flood and drought management project, drainage modelling, storm surge and sea level rise related research and studies in collaboration with BUET, DOE, BWDB, World Bank, CEIP-I and other government and international organizations for many years. And hence, the idea of starting a full-blown unit focusing solely on climate change research has been a vision of IWM for a long time.

Considering the above issues and as per decision of the 84th meeting of IWM board of Trustees, IWM has recently established a Climate Change Cell with a view to conduct (i) Basic research in the field of Climate Change (ii) Climate Change impact assessment, (iii) Training and capacity building, (iv) Awareness building, (v) Developing local level Climate Change model and provide support to develop Climate Change services in line with Bangladesh situation vi) multi-level collaboration with partners, research institutes, stakeholders and donor organizations. The vision of the Climate Cell is to enable better management of the risk of climate variability and changes and adaptation and mitigation to climate change, through the development and incorporation of science-based climate information and prediction into planning, policy and practice on the global, regional and national scale.

Services of Climate Change and Environment (CCE)

Milestone Projects/Activities of Climate Change and Environment (CCE)

Our Milestone Projects

1. Understanding Sea Level Rise Dynamics of Bangladesh along the Coast

Services Provided:
•    Investigate zone wise variation of sea level along the coast (for the three coastal zones separated as West, Central and East)
