| Zusammenfassung |
| Water is an essential input to the majority of human activities. Often,
access to sufficient water resources is limited by quality and infrastructure
aspects, rather than by resource availability alone, and each activity has
different requirements regarding the nature of these aspects. This paper
develops an integrated approach to assess the adequacy of water resources for
the three major water users: the domestic, agricultural and industrial
sectors. Additionally, we include environmental water requirements. We first
outline the main determinants of water adequacy for each sector.
Subsequently, we present an integrated approach using fuzzy logic, which
allows assessing sector-specific as well as overall water adequacy. We
implement the approach in two case study settings to exemplify the main
features of the approach. Using results from two climate models and two
forcing RCPs (representative concentration pathways), as well as population
projections, we further assess the impacts of climate change in combination
with population growth on the adequacy of water resources. The results
provide an important step forward in determining the most relevant factors,
impeding adequate access to water, which remains an important challenge in
many regions of the world. The methodology allows one to directly identify the
factors that are most decisive in determining the adequacy of water in each region,
pointing towards the most efficient intervention points to improve
conditions. Our findings underline the fact that, in addition to water
volumes, water quality is a limitation for all sectors and, especially for the
environmental sector, high levels of pollution are a threat to water
adequacy. |
