Titre : A critical review of water resources in Greece: the key role of agricultural adaptation to climate-water effects Type de document : objet à 3 dimensions, artefacts, ... Auteurs : N.N.

Unquestionably, Greece is a characteristic example of this, as water distribution is highly spatially and temporally unequally distributed, while irrigation and tourist consumers as well as the pollution load are expected to be increased in the near future. Water resources in Greece are particularly affected by climate extremes, with droughts, floods and soil erosion by water being the utmost consequences. Greece consumes the greatest amount of its available water resources in the agricultural sector. Also, there is much evidence of water shortage and bad/poor chemical status of some water bodies, mainly due to saltwater intrusion in coastal agricultural areas and intensively agricultural activities. Therefore, this review provides a literature update on the quantity and quality aspects of water resources in Greece for each water body, focusing on water relation effects (aridity/drought, floods and soil erosion by water). This paper, based on different sources of information and an extensive database of water related data, collects, evaluates and groups data from a quantity and quality point of view for all the different water bodies of Greece. Specific water districts such as the Aegean islands, the eastern part of Crete, Attica and Thessaly are expected to be the most affected by climate-water impacts with reduced crops yields, a greater risk of droughts and/or floods, a loss of agricultural land, declining water availability, and degraded water resources (surface and groundwater). Based on these findings, the proposed review highlights agricultural adaptation practices for increasing water use efficiency, ensuring the sustainability of water resources in Greece.

Titre : The role of climate change in pollinator decline across the Northern Hemisphere is underestimated Type de document : objet à 3 dimensions, artefacts, ... Auteurs : D. Vasiliev ; S.

There is currently no consensus on the main drivers of the decline. Although climate change is expected to drive biodiversity loss in the future, current warming is often suggested to have positive impacts on pollinator assemblages in higher latitudes. Consequently, pollinator conservation initiatives in Europe and the USA tend to lack climate adaptation initiatives, an omission of which may be risky if climate change has significant negative impacts on pollinators. To gain an understanding of the impacts of climate change on pollinator biodiversity in the Northern Hemisphere, we conducted a literature review on genetic, species and community level diversity. Our findings suggest that global heating most likely causes homogenization of pollinator assemblages at all levels of pollinator biodiversity, making them less resilient to future stochasticity. Aspects of biodiversity that are rarely measured (e.g. genetic diversity, β-diversity, species evenness) tend to be most affected, while some dimensions of climate change, such as fluctuations in winter weather conditions, changes in the length of the vegetational season and increased frequency of extreme weather events, that seldom receive attention in empirical studies, tend to be particularly detrimental to pollinators. Negative effects of global heating on pollinator biodiversity are most likely exacerbated by homogenous and fragmented landscapes, widespread across Europe and the US, which limit opportunities for range-shifts and reduce micro-climatic buffering. This suggests the need for conservation initiatives to focus on increasing landscape connectivity and heterogeneity at multiple spatial scales.

In the present study, a comprehensive environmental assessment of the traditional production of wine was performed and the potentiality of a biorefinery system, based on winery waste and aimed at recovering useful bio-based products, such as grapeseed oil and calcium tartrate, was examined through Life Cycle Assessment (LCA). The wine company “I Borboni”, producing Asprinio wine in the Campania Region (Italy), was proposed as a case study. The hotspots of the linear production system were identified and the bottling phase, in particular the production of packaging glass, resulted to contribute to the generation of impacts at 63%, on average, versus 14.3% of the agricultural phase and 22.7% of the vinification phase. The LCA results indicated human carcinogenic toxicity, freshwater eutrophication and fossil resource scarcity impact categories as the most affected ones, with normalized impacts amounting to 9.22E−03, 3.89E−04 and 2.64E−04, respectively. Two side production chains (grapeseed oil and tartrate production) were included and circular patterns were designed and introduced in the traditional production chain with the aim of valorising the winery residues and improving the overall environmental performance. By implementing the circular approach, environmental impacts in the global warming, freshwater eutrophication and mineral resource scarcity impact categories, in particular, resulted three times lower than in the linear system. The results achieved demonstrated that closing the loops in the wine industry, through the reuse of bio-based residues alternatively to fossil-based inputs within the production process, and integrating the traditional production system with new side production chains led to an upgrade of the wineries to biorefineries, towards more sustainable production patterns.

An appropriate agricultural development pathway should be determined, which may include larger land extensions and water consumption or more intensive use of smaller extensions and optimized water use. This study addresses this question in the Eastern Nile Basin countries (ENC), namely Egypt, Sudan, and Ethiopia, where such research is scarce. We utilized open-source datasets, based on relevant remote sensing products and agricultural statistics (harvested area, production, yield, and water footprint [WFP]), to understand the spatio-temporal variability of cropland performance. The study proposes a scenario-based approach that evaluates four development pathways towards sufficient crop production by 2050 in the ENC. While the extensification pathway suggests a continuation of the business-as-usual, i.e., same average WFP and yield values (horizontal scenario), three intensification pathways assume that increased efficiency can improve WFP and yield values (vertical scenarios). Results show that substantial amounts of water and land could be saved by 2050 by following the vertical development pathways. Nonetheless, the three countries, especially Egypt, are expected to face enormous challenges to satisfy their future demand for the main crops by 2050. Our research provides key messages to promote cooperation between the three countries by following a regional benefit-sharing approach to the challenge. The findings of the current study have deep implications on sustainable natural resources development and water and food security in such a vital and conflicted region.
