ii. Objectives :
NARBO’s Charter
• To enhance the capacity in IWRM• To ensure equitable and sustainable use
of WR among various stakeholders• Capacity building of RBOs, Policy
Makers, Line Departments in IWRM• Exchange info, knowledge, lessons
learned in managing WR and in conflict resolution

Environmental Water Security Challenges
• Population increase higher demand for water, exceeding river carrying capacity
• Urbanization concentrates water demand, increased pollution; increased floods
• Drought has transformed from local problem to transboundary health and environmental e.g. haze
• Environment lowest priority• Issues of environmental water security will be
exacerbated by climate change

Water Management Challenges
• Water managed by various ministries and agencies, working in silos and sometimes in competition focus on resource exploitation and economic growth rather than resource conservation and sustainable growth
• Increasing acceptance of the need for holistic management best carried out at river basin level
• Concept of river basin

River Basin Organisation (RBO)
• Role of RBOs extending from water management resource management ecosystem consideration
• Constraint countries are still judged by economic growth eg GDP
• Environmental water security need to improve management of the river basin
• NARBO’s present emphasis building capacity of RBOs (both people and the organisation) develop manuals and models improvement through benchmarking

WHAT IS NATURAL INFRASTRUCTURE?Natural (or “green”) infrastructure: the strategic use of natural ecosystems to provide benefits that substitute man-made physical infrastructure

Examples of NI components
Healthy ecosystems can provide the same services and benefits as man-made infrastructure at lower cost
Natural infrastructure, in many cases, can provide the same services and benefits as man-made infrastructure and at a lower cost.
A well-functioning ecosystem can deliver the equivalent water availability and filtration, flood control and shoreline protection as a major physical infrastructure project.
Investing in ecosystems is often cost-competitive with man-made infrastructure investments for equivalent services.

Natural (Green) Infrastructure
• An opportunity for business • Can help reduce costs, secure access to water• Enhance resilience and sustainability• Contribute to environmental water security• Healthy ecosystem can provide the same
services and benefits as man-made infrastructure at lower cost

Specific and Targeted Recommendations
To achieve Environmental Water Security :• Manage water and environment on a river
basin basis, with greater focus on control at source
• Best implemented by RBOs front liners• Disconnect between different levels• Improve capacity of RBOs• More investments in Natural (Green)
Infrastructure
