Water and Climate
Programme (WCP)
The Northeast India, consisting of the eight
states of Arunachal Pradesh, Assam, Manipur, Meghalaya, Mizoram, Nagaland,
Sikkim and Tripura, presents a distinctive geophysical unit set in the
pristine Eastern Himalayan Region with a unique physiographic framework, a
vigorous monsoon dominated climatic regime and a dynamic hydro-geomorphic
regime. Endowed with a sub (extra) tropical type of monsoonal climate, the
region shows remarkable variability of weather and climate on a regional
scale and forms a distinct climatic zone within the Indian landmass.
Comprising mainly of the basins if three of the large river systems of the
world viz. the Brahmaputra, the Barak (Meghna) and the Irrawady, the NER
possesses the richest treasure-trove of water resources in India. It
possesses about 30% of the total water resources potential and about 41 %
of the total hydropower potential of India. The per capita and per hectare
availability of water in this region is the highest in the country. The NE
India is one of the wettest as well as most acutely flood prone zones of
the world.
The Water and Climate Programme (WCP) of
AARANYAK was launched in the year 2001 and till now its activities have
been carried out by the Water Resources and EIA Division of AARANYAK. The
WCP programme has been conceived to carry out intensive scientific study of
the key issues related to water and climate of the region including the
human and societal dimensions of these issues. Designed initially for a
period of five years (2001-2005) the WCP programme covers the following
activities
-
Comprehensive
assessment of eco-systems of important river basins of the region.
-
Assessment
of environmental impacts of ongoing and proposed water resources
projects such as large river dams.
-
Documentation
of flood & erosion hazards.
Under the Water and Climate (WCP) Programme of AARANYAK
several important programmes were undertaken during this period 2005-2007.
Two workshops were organised at Guwahati and Itanagar on
Hydropower and Biodiversity with support from the Bombay Natural
History Society (Mumbai).
The
Guwahati workshop was held on May 28-29, 2005 at the Indian Institute of
Bank Management, Guwahati while the Itanagar consultative workshop was
Organised at the North Eastern Regional Institute of Science and
Technology, Itanagar, Arunachal Pradesh on May 13, 2006. Both these
successful events were attended by a host of researchers, academicians,
policy makers and civil society leaders. Mr. Newlai Tingkhatra, Honourable
Minister of Environment and Forest, Arunachal Pradesh and the Chief Guest
of the Itanagar workshop appreciated AARANYAK’s efforts to sensitize people
about the natural resources of the region and the impact of development
projects on the environment and the people of the region.
NEW PROJECT ON CLIMATE CHANGE ADAPTATION
The northeastern region is a hotbed of the southwest monsoons which make it
one of the wettest areas in South Asia as well as a hotspot of water
induced disasters. Several studies have predicted significant changes in
the weather-climate and water regimes of the Himalayan region in the coming
decades because of impacts of global climate change. The consequent social,
economic, livelihood and environmental implications in the eastern
Himalayan region are also of immediate concern to scientists and policy
makers. The north-eastern region of India has already been experiencing
rainfall extremes, more frequent and intense floods, moderate to intense
drought like situations, flash flooding due to GOLF (Glacial Lake Outburst
Flood) and LDOF (Landslide Dam Outburst Flood) in the Bhutan and Tibet
Himalayas and increasing river bank erosion and sand casting because of
changing geomorphological behaviour of the rivers. The region suffers
paradoxically both from water excess as well as water crises. Riparian
people of a downstream state like Assam are always at the receiving end
from fluctuating and changing character of rainfall and rivers.
Scores of communities living on the banks of hundreds of the rivers of the
state have traditionally been adapting to different water induced events
and hazards making use of their indigenous knowledge and wisdom. Changes
brought into the hydrological realms of the rivers and the weather and
climate because of climate change, which is primarily of anthropogenic
origin, has thrown the basic premise of the indigenous knowledge based
practices out of gear making it necessary for the coping mechanisms to cope
with the changed geo-ecological and social realities. It makes an
interesting learning of how lives and practices of ecosystem communities
have very slowly but surely been undergoing changes under the clout of
these new environmental situations in a river and water dominated landscape
of Assam. Equally engaging is the fact that amidst the seeming abundance of
water everywhere, there exist many small arid islands where water is never
enough. The Water and Climate Programme of AARANYAK has decided to
explore deep into this dichotomy and study how the concerned communities of
the state have responded then and now to such extremes to survive and
sustain their lives and livelihoods.
AARANYAK has recently launched a study on
Study of changing flood and drought patterns
and documentation of community coping practices in
Assam.
The three main objectives of this study are (i) to document people’s
experiences of the changing nature of rainfall, floods and drought like
situations across the Brahmaputra valley for last 20 years (ii) how
communities in riparian, flood prone and drought prone areas have responded
to and coped with the changing water availability and flooding scenarios
and (iii) examine the changing nature of the floods and drought like
situations in Assam through analysis of hydro-meteorological
characteristics of rainfall(temporal variability and spatial distribution)
and flood(water level and discharge) in the last 20 years since the mega
flood of 1988. Dr. Partha J. Das, Programme Head, WCP is the Principal
Investigator of the project.
This project has been undertaken in response to the recent concerns raised
by the global climate scientist community about the remarkable changes
expected in the hydrological and regimes of the Himalayan river basins due
to climate change. Estimating changes in rainfall and flood
characteristics in the hydro-meteorological context and then integrating
the observations with real life community experiences provides an effective
means of assessing climate change impacts. Studying response to water
stresses, coping mechanism and adaptation strategies that communities have
practised traditionally and have improvised or developed to adjust to
changing water environment in recent times will yield information and
knowledge about adaptation practices necessitated by climate change impacts
in the local context. In addition to the knowledge and practices systems
of communities that have evolved from within the community structure,
external interventions by non-Government and Government agencies such as
information and knowledge input, introduction of new technology and best
practices methods in water management, agriculture, disaster preparedness
etc. also lead to new adaptation techniques or influence the existing ones
to make them more innovative. This is another aspect that will be explored
in this project.
Started as an in-house project, the study will be carried out in some of
the most flood-ravaged and flood prone areas of the state (such in Dhemaji,
Lakhimpur, Morigaon, Kamrup, Barpeta and Dhubri districts) as well as those
that have experienced severe drought conditions in the last twenty years
(Southern part of Nagaon district, Darrang, Golaghat, Karbi-Anglong and
North Cachar districts).
