3. THE MK 16 PROJECT
âș Fostering Evidence-based IWRM in the Stung Pursat
catchment (Tonle Sap Great Lake), Cambodia is jointly
implemented by Tonle Sap Authority, Ministry of Water
Resources and Meteorology, Supreme National Economic
Council, Hatfield Consultant Partnership, and Culture and
Environment Preservation Association.
âș Project recognizes firm relationship between knowledge
and effective water management, and potential for
translating IWRM into better governance practice.
In order to address water resources issues and
develop IWRM capacities, there is a need for
collaboration between related sectors and proper
use of scientific data and analysis to inform
decisions.

4. PROJECT SITE
ï± Stung Pursat is listed as one of Cambodiaâs priority
catchments due to its rich natural resources and wildlife
sanctuaries (many ongoing and future development).
ï± Catchment of 5,965 km2 that discharges an average of 2,818
Million Cubic Meters (MCM) a year into the Great Lake.

8. WHAT AND HOW OF IWRM?
âIWRM is a process that promotes the coordinated development of
water, land and related resources in order to maximize the resultant
economic and social welfare in an equitable manner without compromising
the sustainability of vital ecosystemsâ GWP 2000.
âą
âą
âą
âą
So far, mixed results in the world.
IWRM is not a single, remedial, blueprint plan but rather, a way of seeing
things, managing things, negotiating outcomes and evaluating trade-offs
using state-sanctioned regulations.
IWRM requires both technical solution (access to knowledge and
tools, management ) and governance (institution, organizations, and
communication/participation.
Managing relationships between the various components that make up
catchments:
âą between surface and groundwater, quantity and quality.
âą between water and land use (environment).
âą between water and stakeholder interests.
âą between water-related institutions.

9. Establishing a collective meaning of IWRM
What we want to achieve for Pursat Basin?
ï± Goal of IWRM at the river basin level is to
achieve water security(1) for all purposes, as well
as manage risks while responding to, and
mitigating, disasters.
Water security = capacity to provide sufficient and
sustainable quantity and quality of water for all types of
water services and protect society and the environment
from water-related disasters (ADB).
Food security: without

Path towards water security requires:
ï± resolving tradeoffs to maintain a proper balance
between meeting various sectorsâ needs, and
ï± establishing adaptable governance mechanisms
to cope with evolving environmental, economical
and social circumstances.
10. STAKEHOLDER ANALYSIS
Need to understand the complexity of interests and
motivations, power relation, evaluate and predict impacts, and assess
human capacity.
Provide information regarding:
âą Individuals, groups and institutions that will be affected by and
should benefit from resources development and management;
and
âą Individuals, groups and institutions who can influence, and
contribute to, the resources development and management
processes.
One who has a share or an
interest, as in an enterprise
To be mapped according to their comparative influence (power) and
interest (extent of being affected) within a certain system.

11. LOCALIZING IWRM THROUGH MULTI-STAKEHOLDER
PLATFORM
A BODY OF PEOPLE belonging to
various schools of thought/
perspectives, sectors, expertise, a
nd organizations â government
(national, provincial, and
municipal), CSOs (including
academic institutions), and
community-based natural
resource communities.
A BODY OF PEOPLE who are all
stakeholder
(users, regulators, learners) of
Stung Pursat.
A BODY OF PEOPLE who are
gathered to use the principles of
integrated water resource
management to collectively and
coherently manage the use and
development of Stung Pursat.
Participatory: Based on
consultation with a wide range
of interested and affected
parties;
Informed: Based on wide range
of information; and
Cyclical/iterative: Based on
evolving national
policies, priorities, scientific
finding and systematic
monitoring and evaluation of
existing strategies and policies.

To serve as a problem-solving and planning
platform for concerned Pursat stakeholders to
agree on action and strategies for solving the

together several stakeholders as Pursat catchment
meeting multiple needs and uses of its
community, based on IWRM principles and
informed and collaborative decisions, which
ensure social equity and harmony, and longterm sustainable development
13. TODAYâS EXERCISE
1.
2.
The process of catchment management
A debate on IWRM, which will be organized around three points:
i.
ii.
iii.
3.
Stakeholders: Who are the important stakeholders in catchment
management and how are they different? How can the works of the
most influential be regulated? What is the role of the government
(national and sub-national) and multi-stakeholder platforms?
Human and natural changes: What are the current and anticipated
human-induced and natural changes in the Mekong, and how is your
catchment influenced by and contributing to these changes? What
political and practical implications will this have for catchment
management?
Strategies and Solutions: How can the challenges above be addressed
through governance? What models/ strategies have worked elsewhere?
How can these strategies be adopted for Mekong and your catchment?
What will be the requirements for implementing these strategies?
Questions and Answers session
If interest groups see that their interests are threatened, they would use their powers and influences to prevent other group objectives from being achieved
