Water and Territories

Acknowledgments

Introduction

Part 1. Understanding Local Water Issues

1. The Water Cycle

– The watershed: the territory of water

– Water stocks and flows within the hydrological cycle

– Evapotranspiration, infiltration, and runoff: three possible pathways for precipitation

– Seasonal variability of the different water flows

– The special case of snowpack and glaciers

– Groundwater

– Groundwater circulation and exchanges with the surface

– The different types of drought

2. Factors Affecting the Water Cycle

– Physical factors

– Biological factors

3. Human Impacts and Their Physical Consequences on the Water Cycle

– Water abstraction

– Water uses

– The urban water cycle

– Changes in land cover and land use

– River engineering and modification

– Climate change

– Interactions between climatic and anthropogenic pressures

4. Social Consequences of Climatic and Anthropogenic Pressures

– Social consequences of climate change

– Social consequences of other anthropogenic pressures

– Toward a cumulative effect of climatic and anthropogenic pressures

Part 2. Identifying Action Levers for Territories

5. Social and Political Solutions

– Using and enforcing the legislative and regulatory framework

– Adapting local governance

– Questioning the territory’s carrying capacity

– Adapting lifestyles

– Economic levers and incentives

– Raising awareness about water issues

6. Nature-Based Solutions

– Adapting urban development

– Preserving and restoring ecosystems

– Adapting agriculture

7. Technical and Technological Solutions

– Wastewater reuse

– Improving water networks

– Water transfers between territories

– Hill reservoirs

– Substitution reservoirs

– Artificial aquifer recharge

– Seawater desalination
