ABSTRACT
Life depends on the availability of water, which is both finite and vulnerable. Unfortunately, humans, a small proportion of the living entities in the planet, are responsible for making water availability challenging for all, triggering global changes such as population growth, deforestation, pollution, urbanization and climate change, and therefore it is our responsibility to bring the balance between development and environment back to normal. Arguably, the only way to respond to this situation is by strengthening science, applying and developing technologies that we create, and continually creating new, innovative tools. This chapter reviews some of the past and present technologies for improved water management and provides insights on the future paths they may take.
