The non-linear effect of financial support on energy efficiency: evidence from China

This study examines the non-linear effect of financial support on energy efficiency for 30 provinces in China, over the period 2003 to 2016. Specifically, we find that technological progress is a key factor in improving energy efficiency, regardless of the transition variable or sample chosen. The non-linear effects of the support of different financial sectors on energy efficiency are different. Banks have the greatest positive impact on energy efficiency, but as economic and financial development levels increase, this impact will diminish. The impact of securities on energy efficiency is contrary to bank support, because as the level of economic and financial development increases, the impact of securities on energy efficiency will shift from negative to positive. The impact of insurance support on energy efficiency is not significant

Scenarios of profitability of western Mediterranean demersal fisheries in an effort control regime

7 pages, 1 figure, 6 tables, supplementary data https://doi.org/10.1016/j.jenvman.2021.113794In 2019 a multiannual plan for Mediterranean demersal fisheries came into force with the objective to reduce the overexploitation of fisheries in the region by implementing effort control regimes. These measures, however, have the potential to adversely impact the local employment and profitability of the fisheries. In this paper, we examine scenarios on the short term and long term levels of economic yield of the sector using the two main drivers of fuel price and employment. Three main scenarios are defined as i) maintaining the average status quo, ii) effort control regimes implemented in the 2019 multiannual plan, and iii) flexible effort control regimes. For each of the aforementioned scenarios, three main fleets and five main conditions are considered, and the results will be compared and contrasted. The results in this paper show that the future rise in fuel price, which is anticipated due to global efforts to reduce emissions, along with the current effort reduction strategies could significantly threaten the sustainable profitability of the sector, and policy measures that could balance this issue should be implemented. Policy interventions and investments should be directed at technological advancements such as modernisation and increasing efficiency of fleet to reduce fuel use, utilisation of highly efficient gear technologies, shortened trips to fishing grounds, and increase in value creation in other parts of the fisheries supply chain to mitigate the serious challenges in terms of local employment and profitability facing the Mediterranean fisheriesThe EU provided funding for this research through project “Paradigm for Novel Dynamic Oceanic Resource Assessments” (Horizon 2020 research and innovation programme under the grant agreement No. 773713With the institutional support of the ‘Severo Ochoa Centre of Excellence’ accreditation (CEX2019-000928-S)Peer reviewe

Perception of threats and related management measures: The case of 32 marine protected areas in West Africa

WOS:000541263200027This paper presents the results of surveys conducted with managers of West African Marine Protected Areas (MPAs) and focuses on the threats and the extent to which they are taken into account in the management process. The data and information derived from the surveys are used to provide a reference situation and to develop a complete inventory of threats faced by MPAs in the region. MPA managers identified unmanaged fisheries, coastal erosion, overexploitation of natural resources and pollution as the main threats to the sustainability of MPAs in the region. Climate change, although considered to be diffuse, is also a concern for managers. However, management measures are aimed (predominantly) at preventing overfishing and the overexploitation of terrestrial natural resources. Therefore, coastal erosion, pollution and climate change are only indirectly (and marginally) targeted by these management measures. Moreover, the management measures implemented i.e. monitoring, awareness raising and surveillance are insufficient and mainly aligned with the capacity of the local institutions. However, what is actually needed is more far reaching and adaptive actions to mitigate the current threats. The low financial, technical and human resources largely explain the limited scope of management actions taken. Coupled with the information and data deficit, which increases the inertia regarding threats that have been recurrent for more than a decade, management measures have not been sufficient in managing MPAs in the region. This paper recommends that the links between pressures on MPAs, technical recommendations and resulting management actions must be reinforced
