Spain: Segura River returned to its health (#478)

The Segura Basin in Spain is the driest in Europe. With 365 mm of annual rainfall, this basin has the lowest rainfall in the European Union. Nevertheless, it is also a region which exports fruit and vegetables. The Segura River is thus the main water sources for irrigation. In 1986, when Spain became a member of the European Union, the production of agriculture and canned food significantly increased. As a consequence, a rise in wastewater discharges and lack of water in the already water-stressed Segura River brought extreme deterioration of the water-related ecosystem and a strong social discontent.

Australia: Technological Innovation amidst Complex Regulation in Kalkallo (#470)

Kalkallo project was the first large scale construction project in Australia attempted to harvest and treat stormwater to a standard acceptable for direct injection into water supply system. Because the project was innovative there was no regulatory framework dictating the rules of the game. That was considered as a barrier to move forward. The project turned out to display a high degree of success in some policy dimensions while a negligible degree in some others.

Haiti: The Impacts of the 2010 Earthquake on Water and Sanitation in Port-au-Prince (#469)

On January 12th, 2010 a 7.0 magnitude earthquake hit a point 15 km southwest of Port-au-Prince, Haiti. It led to more than 230 000 deaths and significant physical destructions. The response actions were limited by the underlying vulnerabilities that existed in the country prior to the event and by a lack of coordination among decision-makers. This study intended to improve the understanding of policy-makers, water and sanitation practitioners and researchers on the actions that have been taken and their outcomes in the water and sanitation sector in Port-au-Prince. It revealed that weak governance coupled with poor infrastructure can result in catastrophic scenarios after the occurrence of a disaster.
