Small-scale fisheries make key contributions to food security, sustainable livelihoods and poverty reduction, yet to date the economic value of small-scale fisheries has been poorly quantified. In this study, we take a novel approach by characterizing post-landing trends of small-scale fisheries resources and estimating their total economic value, including both...
The main instrument used in fishery management is the total allowable catch (TAC). Fishery management often fails because TACs are set too high and do not sufficiently restrict fisheries. The question we address in this paper is why do decision makers choose inefficiently high TACs? Our approach is to model...
Human adaptation to change is an essential determinant in the resilience of complex social-ecological systems. In the field of water policy and management it has become increasingly clear that traditional government actors cannot fully address emerging water problems at every scale given a demonstrated lack of resources, increasing variability in...
This research develops a method for estimating discreet changes (shocks) to total factor productivity (TFP) using catch-per-unit-effort (CPUE) and biological stock assessment data. An estimator for identifying jumps in realized volatility is adapted to the identification and estimation productivity shocks. The estimator is tested through simulation and in an application...
Inland fisheries in Mexico represent a source of protein, income and employment, for rural communities. Although the most consumed fish in the country are fresh water fishes in the national statistics they only account for 3% of the total fish catch volume (marine fisheries account for 97%). Demand is higher...
"Human choices affect nature and nature affects human choice". This research is investigated irrigation development on lagoon fisheries in Sri Lanka. Spatial variation of the lagoon system is derived from the land use maps. Information on biological changes of the lagoon and bio-economic conditions were obtained from the secondary data....
Coastal and marine spatial planning (CMSP) is a process for improving the management of ocean resources in order to promote their sustainable development. One of the most challenging spatial planning issues in New England now concerns the siting of offshore renewable energy facilities, mainly wind farms. Commercial fishermen are among...
Ghana's coast is identified with artisanal fishers who use wooden carved canoes and traditional fishing gears. However, little study has been conducted to assess the performance of this industry in terms of its efficiency. This study aims to analyse the technical efficiency and its determinants of the artisanal fishers in...
This paper is a compilation of several themes that addresses how Te Arawa iwi Trusts are utilising kaitiakitanga; traditional methods, practices and customs to manage freshwater environments and freshwater fisheries. Te Arawa is a central north island indigenous tribe of Aotearoa/New Zealand. Several deeds of settlement have been signed with...
In 1986, New Zealand implemented the world’s first comprehensive individual transferable quota management system for fisheries, designed to ensure sustainable use of fish resources by restricting take levels. Today, fewer people are fishing less frequently, often using with more efficient capture technologies. Drawing on ethnographic research with Maori fishing communities...
