Poverty, environment and natural resource use: introduction to the special issue
A growing population and growing per capita consumption threaten the environment and the natural resource base. Where natural resources are at risk, the livelihoods of many are at risk as well. In May 2006 the Environmental Economics and Natural Resources Group of Wageningen University organized a conference on `Poverty, Environment and Natural Resource Use¿ with the aim of contributing to a better understanding of the links between poverty and the natural resource base. The state of the environment affects people's living conditions ¿ and poverty affects environmental quality. Environmental policies cannot be designed and natural resources cannot be managed without appropriate consideration of local people's reactions to those policies and management decisions
Stability of Climate Coalitions in a Cartel Formation Game
We empirically test stability of climate change coalitions with the STAbility of Coalitions model (STACO). The model comprises twelve world regions and captures important dynamic aspects of the climate change problem. We apply the stability concept of internal and external stability to a cartel formation game. It is shown that only if benefits from global abatement are sufficiently high, stable coalitions emerge, though they only marginally improve upon the Nash equilibrium. We explain this phenomenon by analyzing the individual incentive structure of all regions and relate our results to the predictions of theory.International environmental agreements, Kyoto-Protocol, Cartel formation game, Non-cooperative game theory
Pollution abatement in the Netherlands: a dynamic applied general equilibrium assessment
This paper deals with an assessment of the economic costs of environmental policies in the Netherlands, using a dynamic Applied General Equilibrium model with bottom-up information on abatement techniques. Empirical abatement cost curves are used to determine substitution possibilities between pollution and abatement and the characteristics of abatement goods. The results show that an absolute decoupling of economy and environment is possible. Smog formation is the most costly environmental theme, due to the absence of technical abatement options. For all environmental themes, the least-cost way to reduce emissions is via a combination of technical abatement measures and substantial economic restructuring.Applied General Equilibrium, pollution abatement, dynamics, environmental policy, Netherlands

Designing a Decision Support System for Marine Reserves Management: An Economic Analysis for the Dutch North Sea
In this paper we discuss how a Decision Support System (DSS) for managing the marine environment can be set up. We use the Driving force-Pressure-State-Impact-Respond (DPSIR) framework to analyze which are the major driving forces impacting upon the marine environment in the North Sea. Moreover, a number of potential responses are identified. Furthermore, a preliminary and simplified optimization model has been set up and can be used in a DSS to decide on the best location of marine reserves for the protection of species. The model is based on a bio-economic metapopulation model that can be used to decide which parts of the sea should be opened for fisheries and which should be protected as marine reserve. It accounts for the dispersal of fish and considers both the economic returns from fisheries and the ecological value of marine biodiversity. A number of suggestions are given on how to extend and improve the DSS.Decision Support System, Marine Biodiversity Conservation, DPSIR Framework, Bioeconomic Modeling, North Sea
The Effect of HIV/AIDS Driven Labor Organization on Agrobiodiversity: an Empirical Study in Ethiopia
Improved micronutrient intake contributes to delaying the progression of HIV into AIDS and to reducing HIV infection rates. Higher agrobiodiversity in the homegarden contributes to improving the nutritional status of farm households. Farm households with HIV/AIDS affected members observe a decrease in labor supply and productivity causing them to reallocate labor. The reallocation of labor may result in change in agrobiodiversity. Sharecropping is often used to alleviate labor shortage in agricultural production. The purpose of this paper is to analyze the implications of HIV/AIDS on agrobiodiversity through sharecropping arrangements. The study is based on a survey among 205 farm households in the Jimma zone of South Western Ethiopia. Results show that HIV/AIDS driven increase in sharecropping has a positive effect on perennial and overall agrobiodiversity in the homegarden. This offers additional intervention options to mitigate the impacts of HIV/AIDS among farm households.agrobiodiversity, Ethiopia, HIV/AIDS, labor organization, sharecropping, Farm Management, Labor and Human Capital,
Economic Incentives for Entry and Exit in Gum Arabic Agroforestry System in Sudan
The gum tree (Acacia senegal) in the Sahel-Sudan zone has many environmental benign functions. An important function is to control desertification. In this paper we analyze farmers' economic incentives to preserve the existing gum trees and their incentives to create new plantations using a real options approach. Results indicate that agricultural crops provide higher economic benefits as compared to gum agroforestry system. However, on the one hand, as gum arabic is produced during the dry period and land is abundant, there are low incentives for deforestation. Instead, farmers' tend to leave the land idle and let the tree growing. On the other hand, our results suggest that an increase in the prices of gum arabic of about 330 per cent is needed to induce entry and a shift in land use system from continuous agricultural production to gum agroforestry system.gum arabic, deforestation, entry and exit, real options, Sudan, Crop Production/Industries, D4, N5, O13, Q12, Q23,
Alarming signs of serious infections in febrile children: Studies in primary care and hospital emergency care
__Abstract__
Children constitute a substantial part of the workload of physicians in primary care and hospital
emergency care. In the Netherlands, about 70% of the 3.9 million inhabitants less than 20 years
of age had one or more contacts with their general practitioner (GP) in 2011. Primary out-ofhours
care is annually visited by approximately 600,000 children younger than 14 years of age
and hospital emergency departments (EDs) by nearly 400,000 children in this age group.
Fever is one of the most common reasons for children to consult a physician. The incidence
of fever as a reason for contacting primary care is approximately 430 per 1,000 patients/year
under the age of 5 years. The overall incidence rate of the diagnosis of fever (without apparent
source) in primary care is 19.2 per 1,000 patients/year, with the highest rate for children less
than one year (100 per 1,000 patients/year) and the lowest rate for children aged 10 to 17 years
(2.7 per 1,000 patients/year). At the ED, fever is also one of the main presenting problems and
accounts for about 10% to 30% of all visits by children.
Most acute febrile illnesses are caused by self-limiting viral infections, which do not require
antibiotic treatment, diagnostic procedures, or hospitalization. However, a minority of febrile
children develop a serious infection, such as meningitis, sepsis, pneumonia or urinary tract
infection, for which timely diagnosis and targeted therapy are necessary to prevent harm. In
primary care, the annual incidence of serious infections is about 1%, with a peak incidence
rate among the youngest children (0 to 4 years: 21.1 per 1,000 patients/year). At the hospital
ED about 15% to 20% of febrile children are diagnosed with a serious infection. Serious
infections are an important cause of morbidity and mortality, especially in young children.
Infections accounted for about 15% to 20% of all childhood deaths by natural cause in the
Netherlands and the United Kingdom
Costs and benefits of adapting to climate change at six meters below sea level
Climate change increases the vulnerability of low-lying coastal areas. Careful spatial planning can reduce this vulnerability. An assessment framework aimed at reducing vulnerability to climate change enables decision-makers to make better informed decisions about investments in adaptation to climate change through spatial planning. This paper presents and evaluates an approach to assess adaptation options, with the use of cost-benefit analysis
