This paper has two objectives. The first is to estimate the value of implementing new coastal and marine conservation measures in Vietnam, focussing on the relative benefits of water quality improvements, coral conservation and control of marine plastic pollution. The second is to explicitly model any tendency of respondents to fail to give consideration to the “opt-out” or status quo option in a choice experiment, due to social and cultural factors.

Product labelling with eco-certifications is market-based incentive tool for sustainable aquaculture, thus mitigating negative environmental impacts. The aims of this study are to investigate: i) whether consumers prefer eco-labelled (eco-certified) shrimps over conventional (non-certified) shrimp; and ii) whether consumers prefer specific eco-label (eco-certification logo) over others. The study used a discrete choice experiment method and the structured interviews with 353 consumers in Khanh Hoa province and Ho Chi Minh city, Vietnam.

Abstract

Literature has documented significant trade-offs between economic and environmental performance in many areas of agricultural production. However, while it has focused on the trade-off for technically efficient farms there are differing types of trade-offs that exist for differing types of farms. The present paper addresses these gaps in the literature by proposing a more generalised approach to analysing cost and environmental trade-offs. There is also a lack of research on the nature of the trade-off in coffee farming.

This work explores the consequences that different energy poverty definitions and measures might have for the identification of  the  energy poor. Using the  2017 National Survey of  Public Energy Perception applied to  a sample of 3,500 households in Chile, we compare the respective identification outcomes of applying the ten percent rule index (TPRI) and our proposed Perception-based Multidimensional Energy Poverty Index (PMEPI) against the monetary poverty identification outcome.

Key findings

This paper analyses the possibilities for sustainable land use management at farm level to preserve the tropical rainforest in the Lindi region, Tanzania. It investigates the implication of agricultural production, in particular a high valued sesame production on household deforestation in Kilwa district, in Lindi region.
