Geographic Distribution and Niche Divergence of Two Stinkbugs,Parastrachia japonensisandParastrachia nagaensis
2014
Parastrachiidae is a small stinkbug family containing only one genus and two species, Parastrachia japonensis (Scott) (Hemiptera: Heteroptera: Pentatomoidea) and Parastrachia nagaensis Distant. The geographic distribution of the genus has been poorly studied. Niche conservatism refers to that idea that closely related species are more ecologically similar than would be expected, whereas niche divergence predicts they occupy distinct niche spaces. The existence of only two species within one genus suggests niche conservatism or differentiation might exist among them. Herein, the distribution of the genus was mapped, potential distributions were predicted using ecological niche modeling, and …
No evidence of systematic pre-emptive loggings after notifying landowners of their lands’ conservation potential
2020
Landowners can intentionally impair biodiversity values occurring on their land to pre-empt biodiversity protection. This often leads to significant negative effects on biodiversity. We studied whether landowners in Finland engaged in pre-emptive loggings after they were notified that their wooded mires are candidate sites for a mire protection program. After the notification, harvesting rates of the candidate wooded mires were significantly lower compared to harvesting rates of similar but non-candidate wooded mires. Annual and monthly harvesting rates indicated that notifying landowners of the conservation potential did not launch systematic pre-emptive logging behavior. Nevertheless, par…
Economic effects of the consolidation of water utilities in Japan
2014
Water utilities are affected by economies of scale. However, in Japan most water utilities are small-scale water services. Therefore, they face enormous difficulties in terms of financial and personnel resources. To take advantage of economies of scale, the consolidation of water utilities has been promoted since 1965 by Japanese water authorities. The measure has been successful to some extent; nevertheless, consolidation has not progressed in recent years as was expected. This paper identifies the main barriers that hinder the consolidation of water utilities in Japan and describes the new promotion plan for the consolidation of water utilities developed by the Japan Water Works Associati…
Argumentation graphs with constraint-based reasoning for collaborative expertise
2018
International audience; Collaborative processes are very important in telemedicine domain since they allow for making right decisions in complex situations with multidisciplinary staff. When modelling these collaborative processes, some inconsistencies can appear. In semantic modelling (conceptual graphs), these inconsistencies are verified using constraints. In this work, collaborative processes are represented using an argumentation system modelled in a conceptual graph formalism where inconsistencies could be particular bad attack relation between arguments. To overcome these inconsistencies, two solutions are proposed. The first one is to weight the arguments evolving in the argumentati…
A statistical-dynamical downscaling for the urban heat island and building energy consumption - Analysis of Its uncertainties.
2020
AbstractHigh-resolution maps of the urban heat island (UHI) and building energy consumption are relevant for urban planning in the context of climate change mitigation and adaptation. A statistical–dynamical downscaling for these parameters is proposed in the present study. It combines a statistical local weather type approach with dynamical simulations using the mesoscale atmospheric model Meso-NH coupled to the urban canopy model Town Energy Balance. The downscaling is subject to uncertainties related to the weather type approach (statistical uncertainty) and to the numerical models (dynamical uncertainty). These uncertainties are quantified for two French cities (Toulouse and Dijon) for …
The Economic Impact of Water Taxes: A Computable General Equilibrium Analysis with an International Data Set
2006
Water is scarce in many countries. One instrument to improve the allocation of a scarce resource is (efficient) pricing or taxation. However, water is implicitly traded on international markets, particularly through food and textiles, so that impacts of water taxes cannot be studied in isolation, but require an analysis of international trade implications. We include water as a production factor in a multi-region, multi-sector computable general equilibrium model (GTAP), to assess a series of water tax policies. We find that water taxes reduce water use, and lead to shifts in production, consumption, and international trade patterns. Countries that do not levy water taxes are nonetheless af…

Optimal growth and land preservation
1997
A model of optimal economic growth with a constant population subject to a constraint on the availability of land is presented. It takes account of the dual character of land as a production factor and as a consumption good (environmental amenities) by determining the optimal intertemporal allocation of land between productive and recreational uses. An extension of the analysis for the case of a growing population with endogenous growth based on human capital accumulation shows that if the rate of discount is not very low then there exists a set of balanced growth paths compatible with a constant allocation of land. En este trabajo se presenta un modelo de crecimiento económico óptimo con u…
The Southern African Power Pool: An Electrifying Project with Untapped Potential
2017
This chapter turns to infrastructure and gives an outstanding analysis of regional electricity cooperation in the SADC within the framework of the Southern African Power Pool (SAPP). The author illustrates the regional power imbalances in terms of national electricity generation and consumption which fuel the SADC countries’ demand for a regional electricity market and an interconnected regional power grid. It becomes clear that the SAPP’s institutional design is strongly influenced by South Africa as the hub of the existing power network and largest electricity producer. Influence by external actors is supportive of regional electricity cooperation since the EU provides funding for the SAP…
