Revamping the EGU blog network: call for bloggers

Revamping the EGU blog network: call for bloggers

The EGU blog network is getting a make-over! Since 2013 the network blogs have enjoyed thought-provoking and engaging contributions by Simon Redfern, Dan Schillereff and Laura Roberts, Jon Tennant, as well as Will Morgan on a range of topics: from the workings of the inner Earth, through to geomorphology, palaeontology and air quality. However, the individual circumstances of the bloggers now mean that it is no longer viable for them to regularly update their blogs. As such, it is with sadness that we announce that we are saying goodbye to Atom’s Eye on the Planet, Geology Jenga, Green Tea and Velociraptors and Polluting the Internet. From the EGU, we thank Simon, Dan, Laura, Jon and Will for contributing excellent content to the blogs and wish them the very best of luck for the future.

To complete the make-over, we’d like to find new blogs to take the place of the departing network blogs. If you are an Earth, planetary or space researcher (a PhD student, an early career scientist, or a more established one) with a passion for communicating your work, we’d like to hear from you!

We currently feature blogs in international development (Geology for Global Development), geochemistry (GeoSphere), volcanology, (VolcanincDegassing) and geopolicy (Four Degrees). We’d love to receive blog proposals from fields within the Earth, planetary and space sciences we don’t yet feature. The network aims at fostering a diverse community of geoscience bloggers, sharing accurate information about geoscientific research in a language understandable not only to fellow scientists but also to the broader public. You, as an expert in your own research area, are in a better position than we are to share recent development in your area of research.

The benefits: apart from your site gaining exposure by having its posts listed on the front page of the EGU website, we will also share highlights of your work on our social media channels (Twitter, Facebook, LinkedIn, Google+, Instagram) and advertise the blog network at our General Assembly, which has over 12,000 attendees. And, of course, you’ll get to join a great community of bloggers!

With the exception of VolcanicDegassing, the network blogs are authored by early career researchers. In this call for bloggers we are particularly keen to add diversity to the network, and particularly welcome applications from more established scientists.

Having an existing blog is not a requirement for application. However, if you don’t have a blog already, we’d like you to have at least some experience of writing for a broader audience, be it as a guest blogger, or contributing to outlets such as The Conversation, for instance. In this case, let us know what you’d like your blog to be called, what topics you would cover, and link to articles you’ve published in the past.

If you’d like your blog (or blog idea) to be considered for our network, fill out this form by 8th August.

Please note that only blogs in English will be considered, as this is the EGU working language, and the language of the blog network. We particularly encourage applications from all European countries, not just English-speaking countries, but bloggers from outside Europe can also apply.

Feel free to contact the EGU Communications Officer Laura Roberts if you have any questions. In the meantime – happy blogging!

Geosciences Column: The World’s Soils are under threat

Geosciences Column: The World’s Soils are under threat

An increasing global population means that we are more dependant than ever on soils.

Soils are crucial to securing our future supplies of water, food, as well as aiding adaptation to climate change and sustaining the planet’s biosphere; yet with the decrease in human labour dedicated to working the land, never have we been more out of touch with the vital importance of this natural resource.

Now, the first-ever comprehensive State of the World’s Soil Resources Report (SWRS), compiled by the Intergovernmental Technical Panel on Soils (ITPS), aims to shine a light on this essential non-renewable resource. The report outlines the current state of soils, globally, and what the major threats facing it are. These and other key findings of the report are summarised in a recent paper of the EGU’s open access Soil Journal.

The current outlook

Overall, the report deemed that the world’s soils are in fair to very poor condition, with regional variations.  The future doesn’t look bright: current projections indicate that the present situation will worsen unless governments, organisations and individuals come together to take concerted action.

Many of the drivers which contribute to soil changes are associated with population growth and the need to provide resources for the industrialisation and food security of growing societies. Climate change presents a significant challenge too, with factors such as increasing temperatures resulting in higher evaporation rates from soils and therefore affecting groundwater recharge rates, coming into play.

The three main threats to soils

Soil condition is threatened by a number of factors including compaction (which reduces large pore spaces between soil grains and restricts the flow of air and water into and through the soil), acidification, contamination, sealing (which results from the covering of soil through building of houses, roads and other urban development), waterlogging, salinization and losses of soil organic carbon (SOC).

Chief among the threats to soils is erosion, where topsoil is removed from the land surface by wind, water and tillage. Increasing rates of soil erosion affect water quality, particularly in developed regions, while crop yields suffer the most in developing regions. Estimating the rates of soil erosion is difficult (especially when it comes to wind driven erosion), but scientists do know that topsoil is being lost much faster than it is being generate. This means soil should be considered a non-renewable resource. When it comes to agricultural practices in particular, soils should be managed in such a way that soil erosion rates are reduced to near zero-values, ensuring long-term sustainability.

Soils contain nutrients, such as nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg) and sulphur (S), crucial for growing crops and pastures for raising cattle. While nutrient balance in soils has a natural variability, farming practices accelerate changes in soil nutrient content. Over-use of soils rapidly depletes the land-cover of nutrients and result in lower food production yields. This imbalance is often remedied by the addition of nutrients; in particular N and P. Excessive use of these practices, however, can lead to negative environmental effects, such as eutrophication (which increases the frequency and severity of algal blooms) and contamination of water resources. The findings of the report advocate for the overall reduction of use of fertilisers, with the exception of tropical and semi-tropical soils in regions where food security is a problem.

Carbon (C) is a fundamental building block of life on Earth and the carbon cycle balances the amount of C which ultimately enters the atmosphere, helping to stabilise the planets temperature. Soils play a significant role in helping to preserve this balance. Soil organic carbon (SOC) acts as a sink for atmospheric C, but converting forest land to crop land saw a decrease of 25-30% in SOC stocks for temperate regions, with higher losses recorded for the tropics. Future climate change will further affect SOC stocks through increased temperatures and fluctuating rainfall, ultimately contributing to risks of soil erosion and desertification and reducing their ability to regulate carbon dioxide emissions. It is vitally important that governments work towards stabilising, or better still, improving existing SOC stocks as a means of combating global warming.

Preserving a valuable resource

The case is clear: soils are a vital part of life on Earth. It is estimated that worsening soil condition will affect those already most vulnerable, in areas affected by water scarcity, civil strife and food insecurity.

Initiatives such as the 2015 International Year of Soil and the production of the SWRS report are fundamental to raise awareness of the challenges facing soil resources, but more needs to be done:

      1. Sustainable soil management practices, which minimise soil degradation and replenish soil productivity in regions where it has been lost, must be adopted to ensure a healthy, global, supply of food.
      2. Individual nations should make a dedicated effort to establish appropriate SOC-improving strategies, thus aiding adaptation to climate change.
      3. Manging the use of fertilisers, in particular N and P, should be improved.
      4. There is a dearth of current data, with many of the studies referenced in the SWRS report dating from the 1980s and 1990s. For accurate future projections and the development and evaluation of tools to tackle the major threats facing soils, more up-to-date knowledge about the state of soil condition is required.

Soils, globally, are under threat and their future is uncertain. The authors of report argue that “the global community is presently ill-prepared and ill-equipped to mount an appropriate response” to the problem. However, adoption and implementation of the report findings might (by policy-makers and individuals alike) just turn the tide and ensure soils remain “humanity’s silent ally”.

Gender equality in the geosciences: is it a numbers game?

Gender equality in the geosciences: is it a numbers game?

Here’s a tricky question for you. Try and name a woman in geoscience who has won an award for their studies in the last 5 years? How about a man? Chances are it is much easier to think of a male geoscientist who has won an award than a female one, but is that because more men win awards in geoscience than women (compared to the number of male and female geoscientists)?

This was the question that was raised at an innovative session co-organised by the European Research Council on ‘Promoting and supporting equality of opportunities in geosciences’, at the European Geosciences Union’s General Assembly in April this year. The session focused on gender based equality, and addressed the experiences of women from subject-based, institutional, national, and organisational levels. As well as the individual experiences described in the session, questions were also asked more broadly of the role of large organisations such as the publishing houses (including Nature and Science), the European Research Council and EGU – with a particular focus on recognition and awards.

Awards are not only useful for career progression for early career scientists (ECS), but also raise the profile of the researchers gaining them, who act as role models for junior staff and students. If women are missing out on awards that could not only impact negatively on the career prospects of those individuals, but also reflect a bigger issue in how women in geoscience are rewarded (or not) for their work.

The EGU has a unique insight into the question of gender equality in the geosciences as it has some data from its members, but also presents several of our discipline’s most prestigious awards and medals, to both advanced and early careers scientists. Alberto Montanari, the outgoing Chair of the EGU Awards Committee, presented the results of an investigation into the balance of male and female award winners.

First, some numbers. Every year the European Geosciences Union awards dozens of prizes to some of the world’s leading geoscientists. These prizes cover Union Medals and Awards, Division Medals, and Division Outstanding Early Career Scientists Awards (previously known as the Division Outstanding Young Scientists Award) . All award or medal nominees must be members of EGU to be eligible. The 2016 awards received 155 nominations, of which 16% were for female scientists. Of the total 49 prizes given this year eight were for female scientists (three of those were for early careers scientists). What is also important to note is the total number of EGU members divided by gender. In 2015, 69% of members were male and 31% were female, with the difference between male and female member proportions more pronounced for early careers scientists.

Secondly came an interesting question – how do we compute gender equality for award winners? Do we calculate the total number of female award winners per female membership percentage, or the total number of female award winners by the whole population of members – male and female? This question raises an interesting dilemma as both methods have positives and negatives. If we calculate the number of female winners by the population of female members then essentially this is saying men and women have an equal chance of winning within their gender grouping. However this masks the potential for women to be underrepresented within the organisation, as is currently the case in EGU right now.

On the other hand if we calculate the number of female award winners by the total population of members (male or female) the female winners become equally as visible as the male winners. This can act as a catalyst that places the EGU as a gender balanced society, which could in theory encourage greater female membership. On the negative side, it does make it more competitive (proportionally) for members that want to win an award, and this is not what gender equality should be about.

When asked which of the two approaches he thought would be more useful in promoting greater gender equality in the geosciences, Montanari said:

“My opinion is that it is more appropriate to refer to the percentage of female awardees over the female membership. I think this is much more protective for women themselves, as awarding excessive recognition weakens the value of awarded women. Many women have confirmed this interpretation.”

He also added:

“This is a delicate question that would deserve a more profound discussion.”

One final thought on this issue, came, repeatedly from both the audience and the speakers. Although it is vitally important that gender equality is addressed in geoscience, it is not the only type of equality that needs to be examined. We need to be aiming for parity in racial, national and disability accessibility, to name just a few areas and it is hoped that in the future, EGU sessions like this one will continue to challenge our preconceptions of equality and fairness in our science.

GeoEd: Planet Press – geoscience news for children

GeoEd: Planet Press – geoscience news for children

Inspiring children to be interested in the geosciences isn’t always an easy task. While dinosaurs, volcanoes and earthquakes are a sure hook (rightly so!), there is also much more to the Earth, ocean and planetary sciences!  Not only that, but new developments happen much more quickly than the lifetime of a textbook, meaning that breaking science is often underreported in the classroom.  However, distilling the complex science behind ocean dead zones, how scientists measure the height of ice sheets and the history of European droughts, into children friendly language which captures the imagination isn’t plain sailing.

In September 2014 the EGU developed the Planet Press initiative – engaging and bitesize press releases for kids, parents and educators to help them get to grips with the latest geoscientific research going on across the world. Planet Presses are primarily aimed at 7 to 13 year olds, but can be used by children in other age groups too!

How are Planet Presses made?

The starting point is a press release – a statement released to journalists to alert them about exciting and newsworthy research published in one of the EGU’s open access journals.

Example of a Planet Press Release: Studying glaciers with animated satellite images, published September 2015.

A Planet Press (PP), is then written in-house by a member of the EGU’s communication team (mostly by the Media and Communications Manager, Bárbara Ferreira), based on an existing EGU press release.

It is reviewed by two scientists, as well as an educator to ensure the science content is accurate and the writing is appropriate for the target age group. In addition, fun printable versions are then made for classroom use.

Because Planet Presses are intended for use across Europe, the final step of the process is to have them translated into various languages. This is done by volunteer scientists and educators.

Planet Press, two years on

Since the start of the project, 36 PPs (out of 36 press releases) have been published. You can download copies of all the existing texts on the EGU website. The texts have been translated approximately 220 times, including into Serbian, Spanish, Russian, Portuguese and many other languages too. This truly herculean task has been accomplished by a team of over 60 volunteers, without whom the Planet Press project wouldn’t be the success it is today. (All figures correct at time of publication of blog post).

“This is one of the most exciting and rewarding projects I work on at the EGU,” says Bárbara. “Planet Press has received incredibly positive feedback from both scientists and educators, and when I presented it at the EGU 2016 General Assembly, many in the audience gave constructive and useful suggestions for improvement, which we’ve since implemented in the most recent texts. Further, whenever we put out calls for volunteers on our social media channels, I always receive plenty of emails from people interested in helping out with Planet Press, and who are extremely keen to dedicate some of their time and energy to getting geoscientific news to kids around Europe (and further afield).”

Lessons learnt and challenges

The coordination of the volunteers is time consuming and one of many side projects and tasks the EGU’s Media and Communications Manager works on. Despite this limitation, the project has received praise from scientists who enjoy seeing their work being made accessible to a younger audience, as well as educators who use the PPs in the classroom.

But it is precisely distributing the texts to a wide number of educators and ensuring it reaches an extensive demographic of children which remains one of the main challenges of the project. Currently, newly produced releases are advertised on the EGU’s social media channels, as well as the EGU’s website and amongst the educators part of the EGU’s GIFT programme. However, many of those who receive the announcements are not the target audience of the Planet Presses, though we are working to change that and get Planet Press to reach more schools kids across Europe.

Not only that, once the texts have been produced and distributed, measuring their impact: how well they do, how useful educators and children find them and how well they achieve their aim of engaging children with the Earth and planetary sciences, remains very difficult to establish and quantify. This is something we are planning on improving in the future.

A final hurdle is the dearth of translations in a number of languages including Slovenian, Russian, Dutch, Croatian and Swedish. So, if you feel inspired to contribute to the effort of translating existing releases, or indeed reviewing the scientific or educational content of the PPs, please contact Bárbara Ferreira.
