Investing in Arms to Secure Water
Where nations depend on resources originating outside their borders, such as river water, some believe that the resulting international tensions may lead to conflict. Homer-Dixon (1999) and Toset et al. (2000) argue such conflict is most likely between riparian neighbours, with a militarily superior downstream 'leader' nation. In a two stage stochastic game, solutions involving conflict are more common absent a leader, where a pure strategy equilibria may not exist. When upstream defensive expenditures substitute for water using investments, a downstream leader may induced an arms race to increase downstream water supplies. Water scarcity may not be a cause for war, but may cause a buildup in arms that can make any conflict between riparian neighbours more serious.
Effects of Great Barrier Reef Degradation on Recreational Demand: A Contingent Behaviour Approach
Degradation of coral reefs may affect the number of tourists visiting the reef and, consequently, the economic sectors that rely on healthy reefs for their income generation. A Contingent Behaviour approach is used to estimate the effect of reef degradation on demand for recreational dive and snorkel trips, for a case study of the Great Barrier Reef (GBR) in Australia. We assessed how reef degradation affects GBR tourism and to what extent reef-trip demand depends on the visitors’ socio-economic characteristics. A count data model is developed, and results indicate that an average visitor would undertake about 60% less reef trips per year given a combined 80%, 30% and 70% decrease in coral cover, coral diversity and fish diversity, respectively. This corresponds to a decrease in tourism expenditure for reef trips to the Great Barrier Reef Marine Park of about A$ 136 million per year.Coral Reef, Recreation, Contingent Behaviour Model, Count Data Models
Het Westland: glastuinbouwgebied of Vinex-locatie?
Aan de hand van een aantal stellingen is in dit rapport een aanzet gegeven voor een politiek en maatschappelijk debat rondom de positie van de glastuinbouw in de gemeente Westland. De stellingen zijn geformuleerd naar aanleiding van een beknopte cijfer- en beleidsmatige analyse. Hierbij zijn de ontwikkelingen van de glastuinbouw in het Westland in het verleden en heden in kaart gebracht plus de plannen voor de toekomst. Daarnaast zijn relevante beleidsnota's van de gemeente Westland, het Stadsgewest Haaglanden en de provincie Zuid-Holland geanalyseerd
