Item type:Publication, Integrating the water-energy-food nexus and LCA + DEA methodology for sustainable fisheries management: A case study of Cantabrian fishing fleets(Elsevier B.V., 2024-11-01)The fishing sector constitutes an important source of economic revenue in northern Spain. In this context, various research studies have focused on the application of the five-step Life Cycle Assessment (LCA) and Data Envelopment Analysis (DEA) methodology to quantify environmental impacts of fishing systems. However, some of them have used environmental indicators that focus on individual environmental issues, hindering the goal of achieving integrated resource management. Therefore, in this study, the Water-Energy-Food (WEF) Nexus is employed as an integrative perspective that considers the synergies and trade-offs between carbon footprint, energy requirements, and water demand. The main objective of this study is to evaluate the operational efficiency and environmental impacts of Cantabrian fishing fleets. To this end, the combined use of LCA and DEA, along with the WEF Nexus, was applied to the Cantabrian purse seine fleet. DEA matrices were generated using the LCA-derived WEF nexus values as inputs to calculate efficiency scores for each vessel. Subsequently, based on the efficiency projections provided by the DEA model, a new impact assessment was performed to understand the eco-efficiency and potential environmental benefits of operating at higher levels of efficiency within this fleet. The average efficiency of the fleet was above 60 %. Inefficient units demonstrated a greater potential to reduce their environmental impacts (up to 65 %) by operating according to efficiency projections. Furthermore, the results revealed a strong dependence of environmental impacts on one of the operational inputs, i.e., fuel consumption. These findings highlight the significance of embracing holistic approaches that combine technical, economic, and social factors to achieve a sustainable balance in fisheries systems. In this regard, the five-step LCA + DEA method applied in conjunction with the WEF Nexus emerged as a suitable tool for measuring operational and environmental objectives. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Technological innovation and eco-efficiency in manufacturing companies: Does co-innovation orientation matter?(Elsevier Ltd, 2024-04-10)The rising need for sustainable development poses a critical challenge for manufacturing companies, requiring a fresh perspective on adopting greener practices. One recent approach to enhancing sustainability in manufacturing is the development of innovations in the pursuit of achieving higher eco-efficiency. This study delves into this approach by investigating the effect of technological innovation on eco-efficiency. In addition, this research examines the role of co-innovation orientation in relation to suppliers and customers. In the empirical exercise, an ordered probit model is applied to a sample of 791 manufacturing companies from Peru. Our research reveals a positive association between the distinct types of technological innovation and eco-efficiency, with process innovation yielding the most substantial effect. In terms of co-innovation orientation, we find co-innovation with suppliers to be more effective in driving eco-efficiency through product and process innovations, while co-innovation with customers seems more influential through product-service innovation. We also found that, for companies co-innovating with suppliers (CIS), complementary co-innovation with customers does not influence eco-efficiency. Conversely, for those co-innovating with customers (CIC), the fact that they also co-innovate with suppliers significantly boosts eco-efficiency.
