Climate Change and Water

The Technical Paper addresses the issue of freshwater. Climate, freshwater, biophysical and socio-economic systems are interconnected in complex ways. Hence, a change in any one of these can induce a change in any other. Freshwater-related issues are critical in determining key regional and sectoral vulnerabilities. Therefore, the relationship between climate change and freshwater resources is of primary concern to human society and also has implications for all living species.

Human health. In Climate change 2007: Impacts, adaptation and vulnerability,

This volume illustrates the impacts of global warming already under way and the potential for adaptation to reduce the vulnerability to, and risks of climate change.

Climate impacts on energy systems: key issues for energy sector adaptation

This report is intended as an up-to-date compendium of what is known about weather variability and projected climate trends and their impacts on energy service provision and demand. It discusses emerging practices and tools for managing these impacts and integrating climate considerations into planning processes and operational practices in an environment of uncertainty

Adaptation options in water supply

The objective of this report is estimate the influences of climate and socio-economic changes by 2030 on the water supply production facilities of individual nations assuming reasonable measures are taken by them to respond to or adapt to these driving forces. The costs of the adaptation measures are also calculated. Production facilities include reservoir storage, wells, reclaimed municipal and industrial wastewater, and desalination. The analysis was done for two climate change scenarios; one favoring greenhouse gas (GHG) mitigation and the other favoring continued growth in emissions.

Ecosystems,their properties, goods, and services. Climate Change 2007: Impacts, Adaptation and Vulnerability

In this chapter the focus is on the properties, goods and services of non-intensively managed and unmanaged ecosystems and their components (as grouped by widely accepted functional and structural classifications, Figure 4.1), and their potential vulnerability to climate change as based on scenarios mainly from IPCC (see Chapter 2 and IPCC, 2007). Certain ecosystem goods and services are treated in detail in other sectoral chapters (this volume): chapters 3 (water), 5 (food, fibre, fisheries), 6 (coasts) and 8 (health).

Costs of adaptation to climate change impacts on fresh-water systems: existing estimates and research gaps

Information on the cost of adaptation in freshwater systems is necessary to better design strategies to face climate change and water management. We look at the existing estimates with the aim of identifying research gaps. Our analysis shows that case study-specific literature is scarce, fragmented, and not always methodologically transparent. At the same time, most existing global assessments are likely to represent underestimates and rely heavily on each other. We conclude that a clear conceptual framework is still missing.

Managing Mangroves for Resilience to Climate Change

This paper is an attempt to provide some considerations for conservation practitioners as they design conservation strategies for mangroves.

Weather and Climate Resilience: Effective Preparedness through National Meteorological and Hydrological Services.

The report underscores the urgent need to strengthen National Meteorological and Hydrological Services, especially those in developing countries, and provides cost-benefit estimates of the return that countries can hope to achieve.

The economics of coastal management: a manual of benefit assessment techniques.

This practical manual assesses the procedures necessary for protecting vulnerable coastlines against flood, storm, high tide and related environmental damage.

Project Appraisal and Planning Twenty Years On

This paper discusses the use and usefulness of social cost-benefit analysis. An analysis of the value of project appraisal under uncertainty is provided.
