Uttarakhand integrated and resilient urban development project : assessment phase Dehradun

This report 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 already started with 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, which includes, geologic, water resources and water quality systems. Institutional and governance system where we look at both the theoretical and the practical functioning of the system in view of the set policy agenda. 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. These scenarios describe realistic possible future developments in terms of factors (e.g., population and tourism developments, water needs and wastewater generation, but also rainfall variability and drought occurrence) that will define and scope the needs for sustainable solutions. Both the baseline assessment and scenario building benefit from modelling works based on modelling of hydrology, flood mapping, groundwater modelling, and landslide mapping under different climate scenarios. The results from the described tasks will be integrated in an integrated risks and impacts assessment in key watersheds and urban areas in Dehradun and Nainital providing a good 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 what it intends to do. It also presents the main conclusions that will be elaborated and substantiated in the following chapters and in the annexes. Chapter 2 explains the present situation, including the present problems. A look ahead (socio-economic and climate scenarios) identifies which drivers/pressures are or will be there in the future and how the city might react. Chapter 3 focuses on the analysis and assessment. Risks and possible consequences are made clear for the present as well for several climate- and socio-economic development scenarios. This chapter is taking issues as leading themes. Chapter 4 looks ahead identifying zones or hotspots requiring interventions to make the cities climate resilient.
