“…In Europe, diverse studies examined the effect of global warming and climate change upon soil functions. Hamidov et al (2018) reviewed twenty such studies and established a link to Sustainable Development Goals (SDGs). There most revealing findings were as follows: (a) adaptation options reflect local conditions; (b) reduced soil erosion threats and increased soil organic carbon are to be expected, but soil compaction may increase in some areas; (c) most adaptation options are anticipated to improve soil functions; and (d) the fact that soil functions are interrelated requires improving food security and promoting sustainable agriculture by properly addressing climate change (Hamidov et al, 2018).…”

Crops, livestock and seafood are major contributors to global economy. Agriculture and fisheries are especially dependent on climate. Thus, elevated temperatures and carbon dioxide levels can have large impacts on appropriate nutrient levels, soil moisture, water availability and various other critical performance conditions. Changes in drought and flood frequency and severity can pose severe challenges to farmers and threaten food safety. In addition, increasingly warmer water temperatures are likely to shift the habitat ranges of many fish and shellfish species, ultimately disrupting ecosystems. In general, climate change will probably have negative implications for farming, animal husbandry and fishing. The effects of climate change must be taken into account as a key aspect along with other evolving factors with a potential impact on agricultural production, such as changes in agricultural practices and technology; all of them with a serious impact on food availability and price. This review is intended to provide critical and timely information on climate change and its implications in the food production/consumption system, paying special attention to the available mitigation strategies.

“…Regarding the latter, we believe that this is a desirable trait in Verticillium biocontrol agents, but future experiments are needed to assess the effect of the salt-tolerant strain XT1 on V. dahliae under saline conditions. Soil salinity is an upcoming problem due to intensive agriculture and climate change, especially in Andalusia, South Spain [67], the world's largest producer of olive oil in the world [9]. According to Kaurichev [68], soils containing more than 0.2% (w/v) soluble salts should be considered as saline soils.…”

Verticillium wilt, caused by the pathogen Verticillium dahliae, is extremely devastating to olive trees (Olea europea). Currently, no successful control measure is available against it. The objective of this work was to evaluate the antifungal activity of Bacillus velezensis XT1, a well-characterized salt-tolerant biocontrol strain, against the highly virulent defoliating V. dahliae V024. In vitro, strain XT1 showed to reduce fungal mycelium from 34 to 100%, depending on if the assay was conducted with the supernatant, volatile compounds, lipopeptides or whole bacterial culture. In preventive treatments, when applied directly on young olive trees, it reduced Verticillium incidence rate and percentage of severity by 54 and ~80%, respectively. It increased polyphenol oxidase (PPO) activity by 395%, indicating an enhancement of disease resistance in plant tissues, and it decreased by 20.2% the number of fungal microsclerotia in soil. In adult infected trees, palliative inoculation of strain XT1 in the soil resulted in a reduction in Verticillium symptom severity by ~63%. Strain XT1 is biosafe, stable in soil and able to colonize olive roots endophytically. All the traits described above make B. velezensis XT1 a promising alternative to be used in agriculture for the management of Verticillium wilt.

“…The studies are categorised (in columns) into broad ''threat'' issues considered in each paper including Climate Change, Land Use Change, Intensive Human Exploitation, Decline in Soil Health or Plastic; followed by detailed listing of threats. Hamidov et al (2018) Lavelle et al (2014) (continued on next page) Hagvar (1998) & ''soil biodiversity''. However, with the removal of the word 'threat' from the search references are being returned that not only report the impacts of climate change on soil biodiversity, but also the ecosystem services provided by soil biodiversity in terms of climate change mitigation (e.g., Lubbers et al, 2019).…”

“…Climate change can impact soil biodiversity both directly and indirectly. Climate change can alter the temperature and moisture regime of the soil thereby impacting soil biodiversity (Aksoy et al, 2017;Hamidov et al, 2018). Climate change can also lead to extreme weather events including heavy rainfall and drought, along with sea level rise.…”

A decline in soil biodiversity is generally considered to be the reduction of forms of life living in soils, both in terms of quantity and variety. Where soil biodiversity decline occurs, it can significantly affect the soils’ ability to function, respond to perturbations and recover from a disturbance. Several soil threats have been identified as having negative effects on soil biodiversity, including human intensive exploitation, land-use change and soil organic matter decline. In this review we consider what we mean by soil biodiversity, and why it is important to monitor. After a thorough review of the literature identified on a Web of Science search concerning threats to soil biodiversity (topic search: threat* “soil biodiversity”), we compiled a table of biodiversity threats considered in each paper including climate change, land use change, intensive human exploitation, decline in soil health or plastic; followed by detailed listings of threats studied. This we compared to a previously published expert assessment of threats to soil biodiversity. In addition, we identified emerging threats, particularly microplastics, in the 10 years following these knowledge based rankings. We found that many soil biodiversity studies do not focus on biodiversity sensu stricto, rather these studies examined either changes in abundance and/or diversity of individual groups of soil biota, instead of soil biodiversity as a whole, encompassing all levels of the soil food web. This highlights the complexity of soil biodiversity which is often impractical to assess in all but the largest studies. Published global scientific activity was only partially related to the threats identified by the expert panel assessment. The number of threats and the priority given to the threats (by number of publications) were quite different, indicating a disparity between research actions versus perceived threats. The lack of research effort in key areas of high priority in the threats to soil biodiversity are a concerning finding and requires some consideration and debate in the research community.
