Integrated Water Resources Management (IWRM)

There can be variation in water availability with respect to time and space and difficulty in managing the water resources.
Global Changes in climate, land use, population and Industrialization etc,,,.
Sustainable management of water can be ensured through integrated approach with Cooperation of various departments and Stakeholders.
WHAT IS “IWRM” ?
The IWRM is a systemic process for the sustainable development, allocation and monitoring of water resources use in the context of economic and environmental objectives.
• First coordinated approach to IWRM
was evolved at UN Conference at b
MAR DEL PLATA in 1977(Argentina).
• Global Consultation on safe water
and sanitation was held in New Delhi
1990.
• Dublin Conference on water and Environment Development of 1992,”Rio de Janeiro “( Brazil).
PRINCIPLES OF IWRM
Principle-1. Freshwater is a finite and
vulnerable resource, essential to
Sustain life, development and the
Environment.
Principle-2. Water development and
management should be based on a
participatory approach, involving
users, planners and policy makers at
all levels.
Principle-3. Women play a central part
in the provision, management and
Safeguarding of water.
Principle-4. Water has an economic
value in all it’s competing uses
should be recognised as an
economic good.
INTEGRATED THREE “E” S
Integrated water resource management is based on the perception of water as an integral part of the ecosystem, a natural resource and a social and economic good, whose quantity and quality determine the nature of it’s utilisation.
THREES “E” s
ECONOMIC EFFICIENCY IN WATER USE:- Because of the increasing scarcity of water and financial resources, the finite and vulnerable nature of water as a resource and the increasing demands upon it, water must be used with maximum possible efficiency.
EQUITY :-The basic right for all people to have access to water of adequate quantity and quality for th sustenance of human Well-being must be universally recognised.
ENVIRONMENTAL AND ECOLOGICAL SUSTAINABILTY:- The present use of the resource should be managed in a way that does not undermine the life- support system there by compromising use by future generations of the same resource.
ASSOCIATED KEY CONCEPTS
– Integrated water resource management, implying.
• An inter- Sectoral approach
• Represention of all stakeholders
– Sustainable development, sound, Socio- economic development that safeguards the resource base for future generations.
WHY IWRM ?
The world’s freshwater resources are under increasing pressure yet many still lack access to adequate water supply for basic needs.
Growth population, increased economic activity and improved standards of Living lead to increased competition for the limited freshwater resource.
HERE ARE A FEW REASONS:-
• Water resource are increasing under pressure from population growth, economic activity and intensifying competition for the water among users.
• Water with drawals have increased more than twice as fast as population of the world’s population live in countries that experience medium to high water stress.
KEY ISSUES IN WATER MANAGEMENT:-
• Water Governance crisis
• Securing water for people
• Securing water for food production
• Protecting vital ecosystem
• Water Governance.
MAIN CHALLENGES:-
-Equitable allocation of water between sectors within river basins.
– Improving productivity and equity of water in irrigation system.
-Optimising and mobilising funds un orders to ensure sustainability or irrigation system.
-Optimising the use of equifers and groundwater.
