It firstly theoretically elaborates the reasons why, and under what conditions, agroecological farming systems have the potential to produce higher incomes than farms that follow the conventional logic. This theoretical exposition is then followed by a presentation of empirical material from a wide range of European countries that shows the extent to which this potential is being realized. The empirical data draw upon different styles of farming that can be described as ‘proto-agroecological’: approaches to farming that are agroecological by nature, but which may not necessarily explicitly define themselves as agroecological. The empirical material that we present shows the huge potential and radical opportunities that Europe's, often silent, ‘agroecological turn’ offers to farmers that could (and should) be the basis for the future transformation of European agricultural policies, since agroecology not only allows for more sustainable production of healthier food but also considerably improves farmers' incomes. It equally carries the promise of re-enlarging productive agricultural (and related) employment and increasing the total income generated by the agricultural sector, at both regional and national levels. While we recognise that agroecology is a worldwide and multidimensional phenomenon we have chosen to limit this analysis to Europe and the economic dimension. This choice is made in order to refute current discourses that represent agroecology as unproductive and unprofitable and an option that would require massive subsidies.

This study focused on simulating future water footprint (WF) of two agronomically important crops (i.e., wheat and maize) using deep neural networks (DNN) method in Nile delta. DNN model was calibrated and validated by using 2006–2014 and 2015–2017 datasets. Moreover, future data (2022–2040) were obtained from three Representative Concentration Pathways (RCP) 2.6, 4.5, and 8.5, and incorporated into DNN prediction set. The findings showed that determination-coefficient between historical-predicted crop evapotranspiration (ETc) varied from 0.92 to 0.97 for two crops. The yield prediction values of wheat-maize deviated within the ranges of −3.21% to 3.47% and −4.93% to 5.88%, respectively. Based on the ensemble of RCP, precipitation was forecasted to decease by 667.40% and 261.73% in winter and summer in western as compared to eastern, respectively, which will ultimately be dropped to 105.02% and 60.87%, respectively parallel to historical. Therefore, the substantial fluctuations in precipitation caused an obvious decrease in green WF of wheat (i.e., 24.96% and 37.44%) in western and eastern, respectively. Additionally, for maize, it induced a 103.93% decrease in western and an 8.96% increase in eastern. Furthermore, increasing ETc by 8.46% and 12.45% gave rise to substantially increasing (i.e., 8.96% and 17.21%) in western for wheat-maize compared to the east, respectively. Likewise, grey wheat-maize WF findings reveals that there was an increase of 3.07% and 5.02% in western as compared to −14.51% and 12.37% in eastern. Hence, our results highly recommend the optimal use of the eastern delta to save blue-water by 16.58% and 40.25% of total requirements for wheat-maize in contrast to others. Overall, the current research framework and results derived from the adopted methodology will help in optimal planning of future water under climate change in the agricultural sector.

Situation Agricole ENTREPRENEURSHIP ENTREPREUNARIAT AGRICULTURAL SECTOR SECTEUR AGRICOLE INNOVATION INNOVATION ENTERPRISES AGRICULTURAL RESOURCES RESSOURCE AGRICOLE RESEARCH CONCEPT CONCEPT Résumé : Through a Systematic Literature Review, this study aims to analyse how the research in agricultural entrepreneurship is approached in the period until 2012 and compare it with the period 2013–2017, which was found by Dias et al. (2019). This comparison allows identifying which research topics are underlined in each period as well as examine different perspectives on the same topic in both periods. Based on articles from the Scopus database, this review identifies two main thematic areas in the period until 2012: “Entrepreneurial Skills and Income Sources”; and “Market and Resources”. Researchers state that farmers can be considered as entrepreneurs and as decision-makers who aim to maximize profits, developing various typologies of agricultural diversification, although conclude that entrepreneurial skills required for diversified farming are different from the ones required in conventional farming. Attending to the increasingly liberalisation of agricultural markets, the literature also focuses on the ways how farmers had recombined existing farm resources into new uses namely land, human, financial and natural resources. In both periods, we conclude that entrepreneurial skills are underlined but, in the period 2013–2017, new research topics were introduced.
