We investigate environmental aspects of agriculture from a welfare economic perspective and show that both positive and negative effects exhibit the character of undepletable externalities. To internalise these externalities while taking equity concerns into account, we propose compensation of...

A great challenge facing future agricultural water policy is to explore the potential for transition from the current myopic competitive (common) exploitation of groundwater resources to a long-term efficient and sustainable allocation. A number of economic and/or command and control instruments...

Depopulation, especially, but not only, rural, has become a major concern across many countries. As one type of place-based policy, irrigation has been claimed to contribute to resettling populations and reducing outward migration, by increasing agricultural output, productivity, and...

Die Herausforderungen des fortschreitenden Klimawandels stellen die globale Landwirtschaft zukünftig vor große Herausforderungen und erfordern durchdachte Anpassungsstrategien. So zählt eine Anpassung des Wassermanagements zu einer der großen Aufgaben, die es zu bewältigen gilt. Änderungen...

The paper discusses the challenges present in the management of groundwater. The theoretical approach of Elinor Ostrom is presented and her study of the management of groundwater in Southern California in the 1960ies is used illuminate how the bottom up process for developing a sustainable...

Die Relevanz der unterschiedlichen landseitigen Mikroplastikeinträge für die Verschmutzung der Meere ist bisher noch weitgehend unklar. Trotzdem hat die Kontamination der terrestrischen Umwelt erhebliches öffentliches Interesse erlangt. Besonders die deutliche Medienpräsenz dieses...

Die in der Nitratrichtlinie vorgegebenen Ziele für die Qualität des Grundwassers konnten bislang weder in Deutschland insgesamt noch in Rheinland-Pfalz (RP) flächendeckend erreicht werden (BMU und BMEL, 2020). In RP befanden sich 2019/2020 35 der insgesamt 117 Grundwasserkörper in schlechtem...

Land subsidence threatens the living conditions of roughly 1.2 billion people worldwide in deltaic regions characterized by soft top soil. Economic activity in deltaic regions requires lowering the groundwater levels to keep the land sufficiently dry to maintain productivity, which, however,...

The interest in promoting food and water security through development projects has led to the need to evaluate the impact of these projects. This study evaluates the impact from transitioning to a modern irrigation technology. Deciding to adopt or not an alternative irrigation technology...

How to keep water and land stress within planetary boundaries is a major challenge for sustainable development in Latin American countries. Using an environmentally extended global multi-regional input-output analysis (GMRIO) approach, this study simulates future land and water demand for...
