Water resources in tourist islands have been severely threatened, especially in the Galápagos Islands, where the increased local population has generated attractive income from the tourist services. In addition, the data regarding water supply and demand are scarce. This study investigates water supply and demand in Santa Cruz, the most populated island of Galápagos. The research encompasses a thorough assessment of the water supply crisis, as well as the quantification of water demand from different categories (domestic, tourist, restaurants and laundries) through surveys, in the absence of water metering. Also, specific water demand was assessed by installing 18 water meters. The results yield a wide range of water consumption, questioning the current assumption of water scarcity. Furthermore, a prognosis of water supply and demand was carried out, and also several intervention strategies were proposed such as rainwater harvesting, greywater recycling, leakage reduction, water meter installation, water demand reduction, as well as seawater desalination to cope with the future population growth. Due to the fragility of the ecosystem, these strategies were assessed through a Multi-Criteria Decision Analysis, considering environmental, technical, economic and social aspects, as well as relevant stakeholders’ perspectives. finally, the water supply network of Puerto Ayora was evaluated in order to understand the need of the current intermittent supply regime. A methodology was developed to estimate the overflow of the domestic roof tanks (a common incidence amongst local population). The results question the practicality of individual household storage. The final results show that the current situation in terms of the lack of water quantity may not be real, as it has been thought for the last decades. The water issues refer more importantly to the water quality, as well as to the lack of proper water management practices.

The spectacular industrial and economic development of the twentieth century was achieved at a considerable environmental cost. The increasingly precarious position of water, the most valuable of natural resources, reflects this trend. Today we have come to realise that concepts of sustainable development need to

This book focuses on how marine systems respond to natural and anthropogenic perturbations (ENSO, overfishing, pollution, tourism, invasive species, climate-change). Authors explain in their chapters how this information can guide management and conservation actions to help orient and better manage, restore and sustain the ecosystems services and goods that are derived from the ocean, while considering the complex issues that affect the delicate nature of the Islands. This book will contribute to a new understanding of the Galapagos Islands and marine ecosystems.​

REGIONAL WATER SECURITY Regional Water Security provides new research on policy innovations that promote the application of demand management and green infrastructure (GI) in managing water resources across regions sustainably. In particular, with regional water security around the world at risk from climatic and non-climatic challenges impacting water quantity and water quality, this book, in addition to providing examples of demand management and GI being implemented in various locations globally, contains in-depth case studies that illustrate how regions, of differing climates, lifestyles, and income levels, have implemented policy innovations that promote the application of demand management and GI to achieve regional water security for humans while protecting and restoring the natural environment. Regional Water Security will be of interest to regional water resource managers, town and regional planners, resource conservation managers, policymakers, international companies, and organizations as well as environmental NGOs, researchers, and graduate and undergraduate students.
