This work falls within the scope of the Energy-for-Water branch of the water-energy nexus and is a contribution to better understand the available water and endogenous energy resources in the Algarve region. Time series for water resource availability, solar and wind power generation potential in the Algarve between 2004 and 2014 are analyzed. Complementarity relations among their trends and seasonal cycles are identified that can improve the efficiency in use of endogenous renewable energies in groundwater pumping.

The great changes caused by the Fourth Industrial Revolution, also known as Digital Transformation, are happening very fast. We are living a new reality of Digital Economy, where technological innovation has a great impact on how projects are managed. This article has the objective to identify what Project Managers appropriate profile should be in order to face this new reality, taking advantage of using new digital technologies to increase the probability of projects’ success and contribute with added value to the economy, the environment, and society.

It is also presented the model proposed by Green Project Management, oriented to sustainability, and is also emphasized the importance of identifying the best approach to follow in the development of a new project in this Digital Economy era, knowing that besides the traditional predictive and agile approaches, there are rising new hybrid approaches, gathering the positive characteristics of the both of them.

The European Union (EU) launched the Common Fisheries Policy (CFP) in the 1970s. Currently, a large part of the CFP has been financed with the European Maritime and Fisheries Fund (FEMP). This research aims to determine whether there is a high degree of homogeneity in the levels of efficiency achieved by the fishing projects financed by European Funds for the period 2014 to 2020.

The Data Envelopment Analysis (DEA) methodology was adopted. The main results showed that there is a high degree of heterogeneity in the level of efficiency achieved by European countries during the analyzed period. Moreover, despite the fact that regional efficiency has been increasing during the years under study, territorial disparities persist over time. This research provides a contribution for policymakers targeting better use of the FEMP funds for the upcoming funding package 2021–2027.

Comparing companies solely based on tax incentives for R&D activities can be misleading. Hence, this research aims to assess how Portuguese companies that make use of tax incentives for R&D activities on an ongoing basis behave in terms of promoting and appropriating value through innovation. From an initial population of 3,156 companies, a final database with 339 Portuguese companies that made use of fiscal credits from 2013 to 2016 was analyzed. The tax incentive program targeted was the Fiscal Incentive System supporting R&D in Enterprises (SIFIDE). Using the analysis of variance (one-way ANOVA), the main results suggest that, considering the internal resources, there are no statistically significant differences between the promotion and appropriation of value through innovation according to the size and age of companies.

The data indicate that good management regarding the generation and implementation of innovations may occur independently of size and age of firms, in the Portuguese case. Albeit the averages of the indicators of value appropriation of the intangible (e.g. patents, trademarks, and new processes), and the efficiencies of assets and liabilities for the promotion of the intangible are different according to the level of technological intensity. These results point to the need to reevaluate the tax incentives for R&D activities, since its generic nature may not meet the different innovation needs arising from the distinctive characteristics of these enterprises and their technological dynamics. Implications and future research directions are provided.

How high-tech SMEs use innovations as strategic factors in a multilevel context of an innovation ecosystem? Driven by this research question this theoretical essay aimed to establish theoretical relations among innovations, strategy, high-tech SMEs, and innovation ecosystems.

We concluded that the reduction of uncertainties of high-tech industries and SMEs can be achieved through the resources exploitation and attraction from a multilevel perspective of innovation, the innovation ecosystem. We developed propositions that inter-relate the themes and identified gaps on the use of innovations as strategy factors by high-tech SMES in an innovation ecosystem metaphor. Future quantitative, qualitative and mixed methods researches are recommended.
