The triple-bottom-line (TBL) approach defines successful fisheries as those which are ecologically sustainable, capable of generating profits to fishermen, and socially accepted. This approach has brought two significant challenges to fishery managers. On the one hand, the TBL approach usually requires new types of data and analysis to guide scientifically-based fisheries assessment. Recent research suggests that scientifically-assessed fisheries have a better likelihood of success compared with scientifically-unassessed fisheries, which represent most developing country fisheries.

Valuing water purification services of forests in China's Sichuan province

Submitted by Petra Hansson on
EfD Authors:

It is widely believed that forests help improve water quality by reducing soil erosion (and hence reducing silt) as well as filtering out nutrients and pollutants carried in water, which allows the municipal drinking water supply sector to simplify or expedite many costly water treatment procedures and thereby save on operating costs. This study statistically quantifies such cost savings in the contexts of China’s Sichuan province, by analyzing how drinking water treatment costs change in response to changes in upstream forest cover.

Energy poverty and the household heating energy transition in rural China

Submitted by Petra Hansson on

The household heating energy transition program in China has led to a sharp increase in household heating costs and has exacerbated energy poverty (high ratios of energy expenditure to income). This program is mandatory, with the goal of alleviating environmental problems and accelerating households’ transition to cleaner fuel. Specifically, it is intended to convert household heating fuel from coal to natural gas (coal to gas), electricity (coal to electricity), or cleaner coal (clean coal replacement), through mandates and subsidies.

COVID-19 Pandemic and Informal Urban Governance in Africa: A Political Economy Perspective

Submitted by Nnaemeka Chukwuone on

The outbreak and spread of coronavirus disease (COVID-19) is probably the most serious global challenge since World War II. While research has paid considerable attention to the technical, epidemiological and public health aspects of the pandemic in Africa, it neglects the social, economic and political dimensions.

Network analysis: a novel approach to identify PM2.5 hotspots and their spatio-temporal impact on air quality in Santiago de Chile

Submitted by César Salazar on
EfD Authors:

Air pollution, particularly PM2.5 particulate matter, is a significant issue in Santiago, the capital of Chile. Santiago’s pollution problem is exacerbated by its unique geographic location nestled against the Andes mountain range in the central valley of Chile. This paper uses network models that were developed primarily to analyze systemic risk in the financial system to identify those locations in the city that are most important for explaining PM2.5 levels.

Value of cleaner neighborhoods: Application of hedonic price model in low income context

Submitted by Vidisha Chowdhury on
EfD Authors:

Municipal solid waste management is a challenging issue in developing countries. An unclean neighborhood could have a significant negative impact on housing property values too as it may lead to numerous diseases in addition to diminished aesthetic value. This study examines the effects of municipal solid waste collection services at the neighborhood level on housing property values using the hedonic price model. We use a sub-sample of nationally representative household survey data from urban areas as well as primary data collected from one of the metropolitan cities in Nepal.

Valuing recreational ecosystem services in developing cities: The case of urban parks in Dar es Salaam, Tanzania

Submitted by Leonie Joubert on

Despite the growing body of evidence showing benefits and values of recreational ecosystem services, in sub-Saharan Africa, such evidence is extremely limited. This is problematic, and may perhaps explain their current poor condition. This study uses a random survey of households residing in Dar es Salaam to value the benefits of urban parks. The estimation is based on random utility framework where different models, with varying assumptions on preference and scale heterogeneity, are estimated.

Assessing the Incorporation of Latent Variables in the Estimation of the Value of a Statistical Life 20-22
