1. INTRODUCTION TO INTEGRATED WATER RESOURCES MANAGEMENT Module 1 Session 1.3: What is Integrated Water Resources Management?

2. Module Objectives
Understand the main elements of an IWRM approach to sustainable management of water resources.
Learn the main basic functions for water resources management which need to be performed at the river basin scale to implement IWRM.
Discuss institutional arrangements and introduce a process-thinking to conduct the water resources management functions.

3. Session 1
IWRM Concept and Focus on Integrated River Basin Planning
Integrated water resources management is a systematic process for the sustainable development, allocation and monitoring of water resource use in the context of social, economic and environmental objectives.

4. IWRM
IWRM is primarily concerned with planning and management of a basin’s shared resources for the benefit of all of the basin states.
Its basis is that the many different uses of water resources are interdependent. That is evident to us all. High irrigation demands and polluted drainage flows from agriculture mean less freshwater for drinking or industrial use; contaminated municipal and industrial wastewater pollutes rivers and threatens ecosystems; if water has to be left in a river to protect fisheries and ecosystems, less can be diverted to grow crops.

6. Key Issues in Water Resource Management
Water governance crisis
Securing water for people
Securing water for food production
Protect vital ecosystems,
Gender disparities

7. Watershed Functions Economic Sustainable Develop- Ecological ment
The function of watersheds is the sustainable provision of goods and services.
Economic
Produce food, timber, fish, hydro power
Sustain livelihoods
Support income generation
Sustainable
Develop-
ment
Ecological
Ensure water flow and quality within the watershed and further downstream
Provide erosion control, soil fertility, biodiversity, clean air, carbon sequestration
Social and Cultural
Support indigenous culture and livelihoods
Provide recreational opportunities

8. IWRM Framework

9. Major Components of IWRM
Enabling Environment
Policies – set goals for water use, protection and conservation.
Legislative framework – the rules to follow to achieve policies and goals.
Financing and incentive structures – allocate financial resources to meet water needs.
Management Instruments
the elements and methods that enable and help decision‐makers to make rational and informed choices between alternative actions
Institutional roles
this is ‘the range of political, social, economic and administrative systems that are in place
