By Nicole van den Berg 

​A challenging task – bridging the gap between the qualitative and quantitative disciplines. I’m Nicole van den Berg, and since the 1st of February, I have been doing my PhD at the UU researching how sustainable behaviour can be better represented in Integrated Assessment Models (IAMs). With the help of my co-promoter dr. Vanessa Timmer, a visiting research fellow at UU and CEO of a non-profit ‘think and do’ tank in Vancouver, I will investigate the sustainable lifestyles field and the social sciences perspective, and how this can be quantified and integrated into IAMs. With the help of prof. dr. Detlef van Vuuren, my promoter at UU and an expert in IAMs, I will analyse to what extent lifestyle change can influence transition pathways in line with the in Paris agreed upon long-term climate objective of limiting global mean temperature increase to 2°C. Furthermore, dr. Lewis Akenji from IGES, a think tank in Japan, is also part of the project, and will be sharing his expertise on sustainable consumption.

​Congratulations to Dr. David Bijl

​Since last Friday February 23rd, 2018, our (former) colleague David Bijl has successfully defended his thesis “Sustainable resource use in the global water-food-energy nexus“ before a panel of five academic (water) resource specialists, and obtained the title of Dr.!

The examination committee consisted out of Prof. dr. Fulco Ludwig (WUR), dr. Holger Hoff (PIK/SEI), Prof. dr. Marc Bierkens (UU), Prof. dr. Kees van Leeuwen (UU/ KWR Watercycle Research Institute), and Dr. Birka Wicke (UU). The first three opponents all interrogated David about the assumptions in and limitations of his developed (integrative) water demand model and analysis. Did he, amongst other things, include grey and non-conventional water resources (e.g. desalination) and how would these influence his results? David explained how some of the elements were included, while others could not due to limitations in the broader interlinked LPJmL model.

Dr. Hoff followed-up by questioning why David did not call his thesis the Energy-Water-Land Nexus as food is a derivative of land and land use? David gave it a thought, and came back by saying that in his current formulation (Food-Water-Energy) he considers tradable commodities while Land in that sense is not. Dr. Wicke also triggered discussion by questioning the title and definitions used in the thesis. She reasoned that “sustainable development” is in essence an oxymoron. How can one move towards  sustainable resource use in a world focused on economic growth and consumption, and did David look into the effects of a systemic change there?

In a classic “saved by the bell” moment, the last opponent was cut off by the echo of ‘Hora Est’. All professors retreated to reflect on Davids performance. After a short intermezzo, the committee returned and granted David the title of Dr. His promotors, Prof. dr. Stefan Dekker and Prof. dr. Detlef van Vuuren, respectively took his oath of good scientific conduct and pronounced the “laudatio” (speech). After a loud applause from the audience, it was finally time to sit back and enjoy the fruits of 4 years of hard work.

David continues to data crunch – though nowadays outside of academia and in medical risk management issues at ValueCare. Although it appears to be a complete change on the exterior, some things remain the same: David has already scheduled  an R-workshop into the agendas of his new colleagues at his new office. ​​

​Last December I went to the Ecology Across Borders Conference, held in Ghent (Belgium). It was organized by the Ecological Societies of Britain, Germany, Austria, Switzerland, The Netherlands and Flanders as well as the European Ecological Federation. Conferences are always good places to present your work, meet lots of new people and develop new ideas. Unexpectedly, I ended up with both a poster presentation and an oral presentation. For the latter I received a Highly Commended Student Talk Prize.​

Once a while you get a chance to talk to a completely different public about your work, and I don’t mean in the pub or at birthday parties. In this case, I was given the opportunity to give a lecture to 12 year old kids from group 8 at the ‘First van der Huchtschool (a Dutch primary school in Soest, the town where I live and where my wife is a teacher in group 4).

Congratulations to Dr. Mart Verwijmeren!

Our colleague Mart Verwijmeren has successfully defended his PhD thesis on interspecific facilitation and critical transitions in arid ecosystems, for which he did lots of heavy fieldwork in Spain (as can be read in a previous blog).

Last Friday he was, as is customary in science, questioned by a committee of professors. The questions touched upon the different subjects he wrote about in his thesis: theory, field experiments and the model he created using his experimental data. Even a question that bordered on social/political science was asked by one of the committee members. We are very proud, as Mart kept his cool and did not let himself be coaxed into giving answers outside his comfort zone. He kept to what he knew based on his research. Overall: very well done and congratulations! He was handed his diploma which was received with loud applause and cheers. His daily supervisor, Prof. Dr. Chris Smit, gave a nice speech, which of course featured the story of Mart, the rental car and fifteen goats. The day was completed with a nice party.

Mart will continue working in our group as a junior lecturer, combining teaching with research. We wish him the best of luck!

Plant diversity in grasslands: the role of the N:P ratio

It is a strong image. Search online for 'Dutch grasslands' and you will find pictures of green grass, black-and-white cows, a ditch and a mill. These are agricultural grasslands. However, when I think of grasslands, I think of semi-natural grasslands, basically nature reserves. These are grasslands filled with grasses and herbs, many of them also endangered plant species. These semi-natural grasslands have been protected for years, but are still threatened. For the past years I have been studying the effect of eutrophication on the species richness in these grasslands.

Outreach in the Caribbean

11/10/2016

​Despite scientists’ strong commitment to the pursuit of knowledge, the public has shown changing trust in the scientific community since the mid 1970’s.  This erosion of trust is often blamed on scientists’ difficulty with communicating their research to the public.  It is up to scientists, then, to find effective ways to communicate their research without compromising the truth.  This call to action is beautifully illustrated by a quote from a Scientific American blog post about communicating science:
“We need to learn to engage without sensationalizing, enchant without deceiving, compel while staying true to the underlying science.”

As young scientists, my research partner Jetske Vaas and I (Elizabeth Haber) are beginning to navigate the world of outreach and public discourse regarding our research.  Briefly, our project aims to provide resources and expertise to facilitate decision-making for invasive plant management in the Caribbean.  You can read a bit more about our project in this previous blog post. 

Earlier this year, we were approached by Sea & Learn Saba, an environmental education and awareness program occurring every October on the island of Saba, to be experts in this year’s program.  We enthusiastically agreed!  During Sea & Learn, each expert presents a public lecture, leads a public field excursion, and goes into 3 classrooms to present an interactive activity.  From 24-28 October, Jetske and I performed these duties and we found the experience extremely rewarding. 

One of the most valuable lessons we learned while completing our whirlwind week of activities came from a source familiar with media and communication: Chizzilala productions on Saba.  Being Sea & Learn experts, Jetske and I were invited for an interview to be aired on Saba TV.  Since neither of us had done a scientific interview with the press before, we prepared as best as we could the answers to general questions such as:
  • What are we doing on Saba?
  • What is Coralita (our invasive plant species of interest)?
  • Why is it a problem on Saba?
  • What can Sabeans do to control Coralita?
  • What is the goal of our research?

We sat down in a park in Windwardside with Adam from Chizzilala and over the course of 2 hours we told the story of Coralita on Saba as we know it so far.  There were times when we got tongue-tied and times when the interview was interrupted by a garbage truck or a group of free-roaming roosters or rabbits, but overall the interview went very well.  We were able to articulate what we wanted to say and we were able to do so in a clear and thorough way. 

When the interview had wrapped-up and Jetske and I were preparing to leave the park, Adam asked us if this was our first press interview as scientists.  He was asking not because we had done poorly in his opinion, but because we are young and at the beginning of our scientific careers.  He has had the opportunity to interview many scientists in all stages of their careers and offered us some thoughtful advice, for which we are very grateful.  Media training is something that many scientists do not receive, although media savviness is an extremely important skill to have.  I’ve summarized his advice below, with hope that you (the reader) may find a helpful tip for your future interactions with the media:
  • You have more than one chance to say what needs to be said.  With taped interviews, it’s easy to re-do a segment.  Sometimes we forget that it’s completely fine to say, “Can I re-do that last part?” 
  • Always restate the question in the answer.  Unless the interview is going to be aired with the interviewer on screen, the producer will edit out the interviewer’s questions.  Restating the question helps the audience know what you’re going to talk about and allows the producer to easily find the segment of the interview on a certain topic.
  • It’s okay to pause.  It’s much easier for the producer to remove a pause than to add one.  As scientists, we sometimes try to squeeze in everything we need to say in a small amount of time.  That’s what we are trained to do when we present our results to our peers in 15-20 minute presentations.  During a taped interview, we can slow down a bit.
  • Show your enthusiasm.  Scientists have gotten a reputation of being boring, although I’ve met many scientists who are incredibly enthusiastic.  Viewers will tune out if you are also tuned out.  Forced enthusiasm is just as repelling as boringness.

​Our interview is still in the hands of the producer, so I can’t include a link to it in this blog post just yet.  The interview should be available on Chizzilala’s Facebook site in a few weeks.  Stay tuned for a link to the interview once it’s published!  If you're interested in following our adventures with Coralita in the Caribbean, you can go to our Facebook page The Coralita Girls

Organizing a workshop

One of the best ways of either setting up – or strengthen - your professional network is to (help) organize a workshop. This seems a daunting task at the beginning, and it is indeed a lot of work, but at the end it is very rewarding. People in your network will really get to know you (in person) and this makes communicating and cooperation afterwards so much easier.

Conference in downtown Montpellier: a work-related holiday?

By Rémon Saaltink & Iris Pit​

As a PhD student you get the opportunity to go to conferences to showcase your research (and also to get a breather from your daily worries in the office; a necessity!). Finally getting out of the lab or office, go abroad, talk to people who inspire you and all will transform in new energy to continue your research. The goal of a conference is to show ongoing or finished research and to network, which may be of great help when finding a new research position like a post-doc.
