Sustaining Water Resources: Environmental and Economic Impact

Water is essential to human health and economic development due to its utilization in sanitation, agriculture, and energy. Supplying water to an expanding world population requires simultaneous consideration of multiple societal sectors competing for limited resources. Water conservation, supply augmentation, distribution, and treatment of contaminants must work in concert to ensure water sustainability. Water is linked to other sectors, and the quantity and quality of water resources are changing. The efficient use of water in agriculture, the largest user of water worldwide, via drip irrigation is described as is the use of energy-intensive reverse osmosis to supplement freshwater supplies. Efforts to manage watersheds and model their responses to severe weather events are discussed along with efforts to improve the predictability of their function. The regional competition for water resources impacts both energy and water supply reliability, which requires that nations balance both for sustainable economic development. The use of water and energy in the US is described which provides a lens through which to both rethink the interrelationship of water and energy as well as evaluate technological developments. Advances in nanotechnology are highlighted as one emerging technology. These results underscore the multifaceted nature of water sustainability, its interrelationship to energy and economic development, and the need to develop, manage and regulate water systems in a concerted manner

Rekonvaleszenz der Demokratie? Die Erholung bürgerlicher Freiheitsrechte im internationalen Vergleich

Nach den Anschlägen vom 11. September 2001 wurden in einigen westlichen Demokratien bürgerliche Freiheitsrechte durch eine verschärfte Sicherheitsgesetzgebung empfindlich beschnitten. Allerdings zeigen sich im folgenden Jahrzehnt deutliche Erholungseffekte, die wiederum zwischen den Ländern variieren. Auf Grundlage von Daten u. a. des Demokratiebarometers gehen wir der Frage nach, welche Faktoren die unterschiedliche Erholung bürgerlicher Freiheitsrechte in 22 OECD-Staaten zwischen 2002 und 2012 erklären können. Dabei zeigt sich, dass ein starkes und unabhängiges Rechtssystem und eine liberale politische Kultur den Wiederaufbau von Freiheitsrechten fördern, während die Betroffenheit von terroristischen Anschlägen keinen signifikanten Effekt auf die Erholung der Freiheitsrechte hat. Die Ergebnisse sprechen dafür, dass Demokratien dann zu einer Selbstkorrektur im Bereich der Sicherheitsgesetzgebung fähig sind, wenn sie durch rechtsstaatliche Institutionen eingehegt werden, die durch eine liberale politische Kultur unterfüttert sind
