CLIMATE RISKS & RIVER RESILIENCE

Experts from India and Bangladesh are collaborating to assess climate risks and build resilience in the Meghna river basin, which supports over 50 million people, including indigenous communities. The basin faces threats from climate change, such as irregular rainfall, rising temperatures, and industrial pollution. With no existing treaty covering the Meghna river, stakeholders aim to improve data sharing and promote sustainable water management through joint research and dialogue. This effort seeks to protect ecosystems and secure livelihoods dependent on the river.

Context:

A three-day conference will bring together experts and stakeholders from India and Bangladesh to evaluate climate risks and explore ways to improve resilience in the Meghna river basin, a shared water system crucial to over 50 million people, including indigenous communities like the Khasi, Garo, and Jaintia. 

Current Status of Climate Change on Indian Rivers (Source: Down to Earth)

  • River temperatures in India may rise up to 7°C by 2100, reducing oxygen levels and harming aquatic life. 
  • Glacial melt in western Indus Basin is increasing river flows; eastern regions see wetter monsoons. 
  • Erratic monsoon patterns are causing more frequent floods and droughts. 
  • Climate change impacts water availability and agriculture in major basins like Krishna. 

Multidimensional implications of climate change on rivers:

  • Hydrological Changes: Altered rainfall patterns and glacial melt cause fluctuations in river flow, increasing floods and droughts (Source: IPCC, 2023).
  • Water Quality: Rising temperatures reduce oxygen levels, harming aquatic biodiversity; increased pollution loads exacerbate contamination (Source: ICIMOD, 2019).
  • Agricultural Impact: Changes in river water availability affect irrigation, threatening crop yields and food security (Source: World Bank, 2022).
  • Socio-economic Effects: Communities dependent on rivers face displacement, loss of livelihoods, and health risks from water scarcity and pollution (Source: UNDP, 2021).
  • Ecosystem Disruption: Altered river ecosystems threaten fish populations and wetlands, impacting biodiversity (Source: IUCN, 2024).

Way Forward (Source: ICIMOD report (2019) on Ganges-Brahmaputra-Meghna basin pollution):

  • Strengthen Integrated Water Resource Management (IWRM): Promote coordinated management of water, land, and related resources across sectors and regions to optimize usage and sustain river ecosystems. 
  • Enhance Cross-Border Cooperation: Encourage bilateral and multilateral agreements between countries sharing river basins (e.g., India and Bangladesh for Meghna basin) for data sharing, joint research, and coordinated climate resilience strategies. 
  • Promote Climate-Resilient Agriculture and Livelihoods: Support farmers with climate-smart practices, drought-resistant crops, and alternative livelihood options to reduce pressure on river water and ecosystems. 
  • Expand Community Participation: Involve local communities, especially indigenous groups, in decision-making and conservation efforts to ensure solutions are inclusive and sustainable.  
  • Invest in Pollution Control and River Restoration: Implement stricter regulations on industrial discharge, enhance river clean-up projects, and restore wetlands and mangroves to improve river health. 
  • Leverage Technology and Data Analytics: Use satellite data, sensors, and AI for real-time monitoring of river flows, pollution levels, and climate impacts to enable proactive management. 
  • Increase Financial Support: Allocate more funding through national and state schemes, international collaborations, and private partnerships for climate adaptation projects targeting river basins. 
  • Raise Awareness and Capacity Building: Educate stakeholders on climate risks and build technical capacity to implement resilient water management and conservation techniques effectively.

Frequently Asked Questions (FAQs)

Climate change leads to altered rainfall patterns, increased frequency of floods and droughts, rising temperatures, reduced water availability, and changes in river flow affecting agriculture, fisheries, and livelihoods.

Rivers like the Ganges, Brahmaputra, Meghna, and their tributaries are highly vulnerable due to their large population dependence and susceptibility to glacial melt and erratic monsoons.

Challenges include unpredictable water flows, pollution from industrial waste, loss of biodiversity, lack of coordinated data sharing, and inadequate infrastructure for water conservation.
