Assam Integrated Flood and Riverbank Erosion Risk Management Investment Program (Tranches 1 and 2; and Multitranche Financing Facility)

As a key area of development for ADB, climate adaptation infrastructure for flood protection and bank erosion protection need to be effectively disseminated. Structural solutions demonstrated to be effective by the project included (i) riverbank protection works with innovative technologies and prosiltation measures; (ii) upgrade of flood embankments; and (iii) construction of sluice gates and one pumping station to improve drainage.

Integrated flood and riverbank erosion risk management (FRERM) programs are highly replicable. For example, the structural (geotextile bags, high embankments), and non-structural (community-based) approaches were replicated in Kaziranga in the Golaghat district even while the program was still ongoing.

Shaanxi Weinan Luyang Integrated Saline Land Management Project

Accessibility to key stakeholders of knowledge captured from projects can maximize their use and continued enhancement. Knowledge developed from this project, including the saline and wetland management guidelines, will be of continuing value to stakeholders; therefore,it should be made accessible to them. Periodic data recording on flood mitigation, losses, saline soils, and wetland benefits should be maintained.

Structural and nonstructural interventions require cohesive and integrated approaches, necessitating long-term planning and consultative processes. For example under this project, safeguard readiness including securing design approval from pertinent agencies should have been pursued more effectively. Project readiness for physical works should be adequately considered in drawing up implementation schedules. Accurate and realistic cost estimates based on detailed technical design can reduce the risk of loan cancellations.

Power Distribution Enhancement Investment Program (Multitranche Financing Facility)

Mobilizing local project management expertise can be beneficial. The modification of the project management consulting contract to increase the inputs of national staff proved beneficial. Local and national staff who work closely with experienced international consultants as part of a team of a competitively selected consulting firm have the opportunity to acquire skills and hone them. This is good and in line with ADB's capacity development objectives in developing member countries.

Sustainable Energy Access in Eastern Indonesia—Electricity Grid Development Program

The results-based lending (RBL) modality provides flexibility to adjust targets adversely affected by unforessen adverse events such as COVID-19. During 2020–2022, the COVID-19 pandemic affected the demand for electricity, lowering the State Electricity Company's (PLN) revenues and creating uncertainty in its investment plans. Sourcing equity financing and implementing ongoing projects within PLN became difficult under such conditions and adjustments were needed in scope and time targets of ongoing works.

Adequate safeguard reporting arrangements with frequency and report templates included in the construction contracts and technical guidance on the implementation of safeguard actions can strengthen project compliance to ADB safeguard requirements. The introduction of program actions through the RBL programs has improved PLN staff's awareness and capacity concerning ADB safeguard requirements. The grievance redress mechanism was found to be an area for further improvement during the evaluation of the previous RBL in Sumatra.
