Economic valuation of environmental benefits of removing pharmaceutical and personal care products from WWTP effluents by ozonation.
2013
Continuous release of pharmaceutical and personal care products (PPCPs) present in effluents from wastewater treatment plants (WWTPs) is nowadays leading to the adoption of specific measures within the framework of the Directive 2000/60/EC (Water Framework Directive). The ozonation process, normally employed for drinking water production, has also proven its potential to eliminate PPCPs from secondary effluents in spite of their low concentrations. However, there is a significant drawback related with the costs associated with its implementation. This lack of studies is especially pronounced regarding the economic valuation of the environmental benefits associated to avoid the discharge of …
Estimating the environmental and resource costs of leakage in water distribution systems: A shadow price approach.
2016
Water scarcity is one of the main problems faced by many regions in the XXIst century. In this context, the need to reduce leakages from water distribution systems has gained almost universal acceptance. The concept of sustainable economic level of leakage (SELL) has been proposed to internalize the environmental and resource costs within economic level of leakage calculations. However, because these costs are not set by the market, they have not often been calculated. In this paper, the directional-distance function was used to estimate the shadow price of leakages as a proxy of their environmental and resource costs. This is a pioneering approach to the economic valuation of leakage exter…
Feasibility Studies for Water Reuse Projects: Economic Valuation of Environmental Benefits
2010
Water reuse is emerging as a promising alternative because it enables water resources to be increased and lowers pollution levels by reducing wastewater. In recent decades, significant technological progress has been made in the field of wastewater regeneration; and project feasibility is now mostly subject to just economic assessment. However, the economic aspect is the least addressed aspect of research into water reuse. This is because private costs are generally considered while the external effects are relegated to a series of statements about the advantages of water reuse. Methodologies used to analyze the economic feasibility of these projects usually focus on internal costs. As a re…
Economic valuation of knowledge-based capital: an International comparison
2020
Abstract This chapter uses an alternative approach to measuring the knowledge intensity of economies to those commonly uses that are based on the aggregation of industries according to selected indicators such as R&D expenditure or labor force skills. We follow an economic approach rooted in growth accounting methodology, determining the contribution of each individual factor (capital and labor) according to the prices of the services it provides. This methodology is applied to six American countries (the United States, Canada, and four Latin-American countries, namely Brazil, Chile, Colombia, and Mexico) and five European countries (France, Germany, Italy, Spain, and the United Kingdom). T…
The value of local climate and weather information: an economic valuation of the decentralised meteorological provision in Kenya
2020
The development of Sub-Saharan Africa will become increasingly constrained by the acute climate sensitivity of livelihood practices. Weather and climate services can improve climate risks to development by informing plans and decisions that ultimately reduce losses/maximize beneficial opportunities from climate variability and change. Yet, such services are typically highly aggregated, and notoriously difficult to communicate, especially to smallholder farmers and pastoralists where the need is greatest. Kenya Meteorological Department (KMD) are decentralizing service provision, and in so doing, offering disaggregated, contextualized, and more easily understandable localized weather and sea…
Feasibility studies for water reuse projects: an economical approach
2006
Usually the methodologies used to analyse the feasibility of water reuse projects are focused on the internal costs. The aim of this paper is to show a methodology to assess the feasibility of a water reuse project taking into account not just the internal impact, but also the external impact (environmental and social, for example) and the opportunity cost derived from the project. Internal benefit is obtained from the difference between internal income and internal costs. Internal income is obtained by multiplying the selling price of reclaimed water and the volume obtained. Internal costs are made up of the sum of investment costs, operating costs, financial costs and taxes. While some of…
The Economic Value of Volunteer Work
2010
Despite the socioeconomic interest that is associated with volunteer work, the practice of valuing it is limited, and few scientific advances have been made. In this context, this study first analyses why these advances are scarce, paying special attention to the limitations of micro- and macro-accounting systems, including volunteer work accounts. It then proposes a method with heuristic capacity for valuing the various economic dimensions of volunteer work. The third part of this article applies this proposal to social and environmental volunteer work in the Spanish region of Valencia. The conclusions bring to focus the fact that whereas the technical obstacles faced in conducting empiri…
Evaluación multicriterio de políticas de uso y gestión de recursos naturales
2014
The purpose of this work is show the characteristics of different environmental economic assessment methodologies, and exposes a case study where possible alternatives addressed to reduce the contamination of a bay with multicriteria approach are evaluated. The results obtained show the effectiveness of multicriteria analysis to evaluate the alternatives for solution of contamination problem in a bay. Economic evaluation of the contamination effects integrated to the environmental, social and economic dimensions through multicriteria techniques allows an alternative planning to solve the environmental problem studied, providing the right decision.
Environmental Benefits of Wastewater Treatment: An Economic Valuation
2009
The need of economic research into the design and implementation of policies for the efficient management of water resources has been emphasized by the European Water Framework Directive (Directive 2000/60/UE). The efficient implementation of policies to prevent the degradation and depletion of water resources requires determining their value in social and economic terms and incorporating this information into the decision-making process. A process of wastewater treatment has many associated environmental benefits. However, these benefits are often not calculated because they are not set by the market. Nevertheless, the valuation of these benefits is necessary to justify a suitable investme…
