Project Description
If provided by the financial institution, the Early Warning System Team writes a short summary describing the purported development objective of the project and project components. Review the complete project documentation for a detailed description.

According to the bank's website, "the Government of Thailand has prepared a detailed masterplan to address climate risks in the Chao Phraya River basin. A sovereign intervention is justified as the private sector traditionally does not engage in flood risk management, nor where there is no direct stream of monetary benefits". Also, the "project's rationale is rooted in the urgent need to address climate-induced flood vulnerabilities, utilize existing infrastructure efficiently, and integrate climate resilience and adaptation into local communities. The fundamental development problem the project addresses is the heightened vulnerability in Lower Chao Phraya region of Thailand to climate-induced floods".

Contact Information
This section aims to support the local communities and local CSO to get to know which stakeholders are involved in a project with their roles and responsibilities. If available, there may be a complaint office for the respective bank which operates independently to receive and determine violations in policy and practice. Independent Accountability Mechanisms receive and respond to complaints. Most Independent Accountability Mechanisms offer two functions for addressing complaints: dispute resolution and compliance review.

ACCOUNTABILITY MECHANISM OF ADB

The Accountability Mechanism is an independent complaint mechanism and fact-finding body for people who believe they are likely to be, or have been, adversely affected by an Asian Development Bank-financed project. If you submit a complaint to the Accountability Mechanism, they may investigate to assess whether the Asian Development Bank is following its own policies and procedures for preventing harm to people or the environment.
