This perspective discusses nine conditions for enhancing the performance of multistakeholder partnerships for sustainable development. Such partnerships have become mainstream implementation mechanisms for attaining international sustainable development goals and are also frequently used in other adjacent policy domains such as climate change, health and biodiversity. While multistakeholder arr...

The awareness of the Sustainable Development (SD) issues and stakeholder interactions in the field of information and communication technologies (ICT) management, forces companies to adopt the concepts of Corporate Social Responsibility (CSR) and Green IT to meet the challenges of innovation agility, and afterwards to create differentiation in the processes of governance and strategic alignment...

This article presents the outcome of research aimed at assisting governments in meeting their commitments and legal obligations for sustainable fisheries, based on increasing evidence that global fisheries are in crisis. The article assesses the effectiveness of the existing legal and institutional framework for high seas living resources. It focuses on: (1) the role of regional fisheries manag...

The sergestid shrimp, Sergia lucens is one of the major marine resources in the waters off southwestern Taiwan. The maximum sustainable yield (MSY), total allowable catch (TAC) and fishing effort at MSY (EMSY) of the sergestid shrimp in this area were estimated to be 1008 tons, 907 tons and 11292 vessel-day, respectively by using the surplus production model with deterministic observation-error...

Fisheries management agencies have to drive resources on sustainable paths, i.e. within defined boundaries for an indefinite time. The viable-control approach is proposed as a relevant method to deal with sustainability. We analyse the ICES precautionary approach (PA) by means of the notion of viability domain, and provide a mathematical test for sustainability. It is found that the PA based on...

Sustainably managing ecosystems is challenging, especially for complex systems such as coral reefs. This study develops critical reference points for sustainable management by using a large empirical dataset on the coral reefs of the western Indian Ocean to investigate associations between levels of target fish biomass (as an indicator of fishing intensity) and eight metrics of ecosystem state....

Bottom trawls are a globally used fishing gear that physically disturb the seabed and kill non-target organisms, including those that are food for the targeted fish species. There are indications that ensuing changes to the benthic invertebrate community may increase the availability of food and promote growth and even fisheries yield of target fish species. If and how this occurs is the subjec...

Tunas and their relatives dominate the world's largest ecosystems and sustain some of the most valuable fisheries. The impacts of fishing on these species have been debated intensively over the past decade, giving rise to divergent views on the scale and extent of the impacts of fisheries on pelagic ecosystems. We use all available age-structured stock assessments to evaluate the adult biomass ...

2 ABSTRACT The Galápagos Islands are one of Earth's last biodiversity edens. As such, the conservation of their terrestrial and marine wildlife, including the sustainable management of local fisheries, is of paramount importance. Although the commercial exploitation of marine resources in the Galápagos did not begin until the 1930s, issues of overexploitation and mismanagement are already of se...
