  3. 3. THE MK 16 PROJECT › 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. › 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. 3
  4. 4. PROJECT SITE  Stung Pursat is listed as one of Cambodia’s priority catchments due to its rich natural resources and wildlife sanctuaries (many ongoing and future development).  Catchment of 5,965 km2 that discharges an average of 2,818 Million Cubic Meters (MCM) a year into the Great Lake. Catchment Area (ha) 1,100,000 900,000 700,000 500,000 300,000 100,000 (100,000) 4

  6. 6. 6 Why Integrated Water Resource Management?
  7. 7. Why Integrated Water Resource Management? (2) Approaches to Water Management: • Ad hoc • Economic Analysis -- Single Project or Basin • Multi-Objective Planning • Comprehensive Multi-Purpose River Basin Planning and Management • Strategic Planning and Implementation through IWRM Demand Supply Supply • Quantity (Natural Scarcity, • Quantity (Natural Scarcity, • Increasing in all sectors Economic Scarcity or Depletion) Economic Scarcity or Depletion) • Inefficient use • Quality Degradation • Quality Degradation • Cost of of Options • Cost Options Demand • Increasing in all sectors • Inefficient use IWRM
  8. 8. WHAT AND HOW OF IWRM? “IWRM 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 ecosystems” GWP 2000. • • • • 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: • between surface and groundwater, quantity and quality. • between water and land use (environment). • between water and stakeholder interests. • between water-related institutions. 8
  9. 9. Establishing a collective meaning of IWRM What we want to achieve for Pursat Basin?  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 water security food security cannot be achieved Source: www.narendramodi.in 9 Path towards water security requires:  resolving tradeoffs to maintain a proper balance between meeting various sectors’ needs, and  establishing adaptable governance mechanisms to cope with evolving environmental, economical and social circumstances.
  10. 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: • Individuals, groups and institutions that will be affected by and should benefit from resources development and management; and • 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. 10
  11. 11. LOCALIZING IWRM THROUGH MULTI-STAKEHOLDER PLATFORM A BODY OF PEOPLE belonging to various schools of thought/ perspectives, sectors, expertise, a nd organizations – 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.
  12. 12. LOCALIZING IWRM THROUGH MULTI-STAKEHOLDER PLATFORM (2) STUNG PURSAT MSP MISSION Existing Drivers To serve as a problem-solving and planning platform for concerned Pursat stakeholders to agree on action and strategies for solving the identified problem based on knowledge and a strong convening power to help increase trust/confidence among stakeholders and facilitate agreements between various interest holders/groups Internal Forces External Forces Water Vision/ Policy Outputs INITIATION MSP Established as an informal platform Activities Awareness in IWRM Government Commitment STUNG PURSAT VISION MK 16 has initiated the MSP as an informal Green and prosperous discussed. platform and broughtfor 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. 13. TODAY’S 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
