TO BE ANSWERED ON 23.03.2026
Climate Vulnerability in Assam
4917. MD. RAKIBUL HUSSAIN:
Will the Minister of ENVIRONMENT, FOREST AND CLIMATE CHANGE be pleased to
state:
(a) whether the Government has carried out any assessment of flood, erosion and climate
vulnerability in Assam, particularly along the Brahmaputra and Barak river systems and if so,
the details thereof, district or river-basin-wise;
(b) the major findings of such assessments, including identification of highly vulnerable
districts;
(c) whether funds under national and international climate adaptation programmes have been
sanctioned, released or delayed for Assam; and
(d) the steps taken to fast-track erosion control, flood mitigation and climate-resilient
infrastructure in the State?
ANSWER
MINISTER OF STATE IN THE MINISTRY OF ENVIRONMENT, FOREST AND
CLIMATE CHANGE
(SHRI KIRTI VARDHAN SINGH)
(a) to (d) The occurrence of floods can be attributed to various factors, including wide
variations in rainfall both in time and space with frequent departures from the normal pattern,
inadequate carrying capacities of rivers, river bank erosion and silting of river beds, landslides,
poor natural drainage in flood prone areas, snowmelt and glacial lake out-bursts.
Morphological Studies by various Indian Institute of Technology (IIT) and National Institute
of Technology (NIT) have been carried out for major rivers including river Brahmaputra. These
Studies play an important role in understanding the nature of rivers in a comprehensive manner
and provide assessment of decadal bank-line movement, erosion & deposition in different
reaches in respect of base year, derivation of reach-wise morphological indices and
identification of critical reaches. These studies have been shared with concerned State
Governments and other stakeholders etc. for taking informed decision and future planning.
As per the morphological study of Brahmaputra River conducted by Central Water
Commission (CWC) through IIT Guwahati, it has been estimated that in the Brahmaputra River
a total erosion of 252.6 sq.km and deposition of 118.6 sq.km occurred between 2003-05 and
2008-11.
As per report of CWC on “Assessment of Area Affected Due to Floods in India, 2024” based
on satellite imageries data from 1986 to 2022, the total flood affected areas in Assam
is assessed as 2.477 Mha covering 33 of 35 districts.Further, Department of Science and Technology through Assam Climate Change Management
Society (ACCMS), Environment, Forest and Climate Change Department, Government of
Assam has also supported a study to conduct the vulnerability mapping of Indian States and
published the report “Vulnerability Profiles for India: State and District Level using a Common
Framework”. This assessment covered both the Brahmaputra and Barak River valley. The
vulnerability report identifies Assam as the 5th most climate vulnerable State in India.
Flood management and anti-erosion schemes are planned and implemented by the State
Government, while the Central Government supplements the efforts through technical
guidance and financial assistance under various programmes.
Government of India has adopted integrated approach to flood management that aims at
adopting judicious mix of structural and non-structural measures to provide a reasonable degree
of protection against flood damages. Central assistance has been provided to Assam under the
Flood Management Programme (FMP) and its continuation as the Flood Management and
Border Areas Programme (FMBAP) for works such as flood control, anti-erosion measures
and drainage improvement.
The State Government also undertakes assessment of damages caused due to natural calamities
including floods and provide relief assistance from State Disaster Response Fund (SDRF)
already placed at their disposal as per Government of India’s approved norms. Additional
financial assistance is provided from National Disaster Response Fund (NDRF), as per laid
down procedure in case of disaster of ‘severe nature’ which includes an assessment based on
the visit of an Inter-Ministerial Central Team (IMCT).
In addition, non-structural measures such as flood forecasting and early warning services are
provided by the CWC. In order to enable States to undertake scientific assessment of flood
plains and its zoning as a non-structural measure of flood mitigation, Ministry of Jal Shakti in
August 2025 has prepared Guideline on Flood Plain Zoning and circulated to States/UTs.
Further, under National Adaptation Fund for Climate Change (NAFCC), a project on
“Management of Ecosystem of Kaziranga National Park by creating Climate Resilient
Livelihood for Vulnerable Communities through Organic farming and pond based
Pisciculture” is implemented in the State of Assam with a project cost of INR 24.56 crores.
