Uttarakhand integrated and resilient urban development project : assessment phase Nainital

This report has been conducted through ADB’s Technical Assistance Special Fund-other sources and the Climate Change Fund, on a grant basis. It describes the results of the assessment phase of the project “CLIMATE RESILIENCE MODELING, PLANNING, AND DESIGNING for DEHRADUN and NAINITAL” or formally: ADB TA-6840 IND: Uttarakhand Integrated and Resilient Urban Development Project - IND 01: Firm on Climate Resilience Modelling, Planning, and Designing (38272-044). The objective of the consulting services is to support the Government of Uttarakhand in enhancing climate resilience in two major cities: Dehradun and Nainital. The situation analysis forms the basis for the rest of the project. It started with a collection of available reports and information in the Inception phase and then followed a structured approach. First, the baseline assessment is conducted for the socioeconomic and infrastructure situation and existing plans, the natural resources system (including geologic, water resources, and water quality systems), and institutional and governance systems. Based on the baseline results, the needs for additional surveys will be established and discussed with the client. Parallel to the baseline assessment, different climate and socio-economic scenarios were developed, describing realistic possible future developments in terms of factors like population and tourism developments, water needs and wastewater generation, and rainfall variability and drought occurrence. Both the baseline assessment and scenario building benefit from modeling works based on hydrology, flood mapping, groundwater modeling, and landslide mapping under different climate scenarios. The results from these tasks will be integrated into an integrated risks and impacts assessment in key watersheds and urban areas in Dehradun and Nainital, providing insight into the vulnerability of different parts of the cities to present and future hazards. Chapter 1 introduces the relevance of the assessment, gives the background of the project, and presents the main conclusions. Chapter 2 explains the present situation, including the present problems, and looks ahead at socio-economic and climate scenarios. Chapter 3 focuses on the analysis and assessment, making clear the risks and possible consequences for the present and several climate- and socio-economic development scenarios. Chapter 4 identifies zones or hotspots requiring interventions to make the cities climate resilient.
