The meeting reviewed the most pressing problems related to groundwater management in selected case study

sites (Metro Cebu, Bohai Coastal Zone, Jakarta, and Lower Mekong Delta). During discussion, available

examples for addressing those problems were examined. It was supplemented by reviewing practical use of

groundwater modelling tools to assess saltwater intrusion and land subsidence in the context of the

Netherlands, exposure visit to Amsterdam Dunes Water Supply to observe measures taken to monitor

groundwater salinity and recharge fields to minimize impacts of seawater intrusion, review of land

subsidence monitoring in China, and application of Groundwater Sustainability Index in Kathmandu.

As a reference, all details of inception meeting (including presentation slides) are uploaded in the

Groundwater Knowledge Hub webpage.

Following summarizes the main outcomes of the meeting:

Major groundwater problems Like other groundwater dependent areas, all case study areas are already affected by groundwater related

problems mainly related to over-pumping and pollution of aquifers. More specifically, four major problems

were identified that required immediate attention.

Case study sites Lowering of groundwater level

Sea water intrusion

Land Subsidence

Pollution (point and non-point sources)

Metro Cebu ○○○ ○○○ ○○ ○○ Bohai Coastal Zone ○○○ ○○○ ○○○ ○ Jakarta ○○○ ○○○ ○○ ○○○ Lower Mekong Delta ○○○ ○○○ ○ ○○

○○○: Serious problem; ○○: Problem less serious but increasing; ○: Potential future problem

Matching of common management challenges

While major problems are common to all case study areas, but management is rather complex due to

uniqueness of each problem in terms of terrain, rainfall and climate, geomorphology, aquifer types and

distribution, land uses, size of recharge areas, water quality, variable abstraction and uses, and legal and

institutional framework. Despite uniqueness of problems, three types of mutually interlinked management

challenges could be identified as shown in the following figure:

Insufficient or lack of

information about the extent

of each problem

Weak monitoring capacity

(networks, instruments and

staffs, frequency of

observation)

Poor understanding about risk

scenarios and appropriate

management measures

Management challenges

to problems (depletion,

seawater intrusion, land

subsidence)

Insufficient or lack of information about each problem is the main barrier for undertaking management

actions. This situation is mainly caused by weak monitoring capacity of groundwater related information

such as fewer monitoring networks, lack of adequate instruments and staff to undertake monitoring at regular

intervals and inadequate observation frequency. In the absence of such fundamental details there is also poor

understanding about the risk scenarios and appropriate management measures.

Methodological approach Under existing situation it was identified that an integrated diagnostic approach should be adopted to identify

extent of problems, risk involved, and the most feasible mitigation options. For that three strategies were

identified:

- Understanding the state of problems and future risk scenarios through the adoption modelling tools

- Development of Coastal Groundwater Governance Index

- Effective dissemination of groundwater related information and findings to relevant stakeholders

Modelling was identified as an effective tool that helps in fulfilling following tasks:

- Systematic collection of information and their organization. It will help in finding out the

information gaps that should be overcome in future;

- Based on the collected information, conceptualize the state and dynamics of groundwater resources

and spread of the problems;

- Assessing future risks (including seawater intrusion due to climate impacts) and formulating

strategies for management actions

While modelling serves in enhancing understanding of groundwater problems and depicting risk scenarios

clearly, equally important is to analyze legal, institutional, and socio-economic setting essential for

controlling mismanagement of the resources such as unsustainable groundwater abstraction, pollution of

aquifers. For that a comprehensive Coastal Groundwater Governance Index will be formulated which

helps in identifying critical gaps in governance in a comparative manner by covering following areas:

- Adequacy of information base;

- Legal, regulatory and institutional environment;

- Level of public awareness about resource potentials and limitations;

- Socio-economy of resource abstraction and uses;

It is crucial that outcomes from modelling as well as the governance index are communicated in timely

manner to indented stakeholders. So information dissemination is a critical aspect of this project. For that

necessary arrangements will be made for sharing project activities and outcomes through project web site in

the Asia-Pacific Groundwater Knowledge Hub webpage, publications and seminars. Particularly, main

objectives of information dissemination will be to identify areas where immediate attention are critical to

safeguard future resource sustainability in terms of improving monitoring technology and infrastructure,

enhancing management skills, strengthening legal and institutional actions, policy responses and promoting

cooperation among coastal cities to tackle with future groundwater problems.

Working Plan

During the meeting working plans were developed for all case studies. Among the activities, data collection

and conceptual groundwater model development were the immediate priorities because they will be reviewed

during the Analysis Workshop to be held tentatively during the weeks of 24th March-4

th April, 2013 at Ho

Chi Minh, Vietnam. Before the analysis workshop overview training on the use and application of

groundwater model in each case study area will be provided to the project participants by UNESCO-IHE.

During the analysis workshop, a framework of Coastal Groundwater Governance Index will be developed

along with the participants based on the collected data. Based on the outcomes of analysis workshop,

existing plan will be revised according to the necessity for further data collection and field activities.

Following table briefly shows the activities to be completed in each case study site:
