The observatory is one of few places in the world where visitors can come into close contact with gigantic, working telescopes. The visitor center, built with minimising climate impact as a goal, is made a large extent of reused material. </b></p><div><div>Onsala Space Observatory at Chalmers is a facility for scientists who want to understand both the universe and our planet, the Earth. Here, young people and the general public can come into close contact with the latest technology for understanding space and big questions in astronomy and Earth sciences.</div> <div><br /></div> <div>&quot;Today we have more and larger telescopes at the observatory than we have ever had before. They are awesome to look at, and the work they do is just as impressive. We look forward to meeting curious guests of all ages in the future&quot;, says Eva Wirström, astronomer and deputy director of Onsala Space Observatory.</div> <div><br /></div> <div>Curiosity is a driving force for both researchers and visitors to the observatory, argued Chalmers President Stefan Bengtsson in his speech during the opening ceremony on 27 September.</div> <div><br /></div></div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div><img src="/SiteCollectionImages/Institutioner/SEE/Nyheter/Invigning-Stefan-220.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" /><div>&quot;The opportunity for scientists to determine the direction of their research, with their own curiosity as a compass, is something we at Chalmers value highly. The mind must be free - only then can unexpected and ground-breaking discoveries be made! I hope and believe that the visitor center will be a place for inspired meetings - here children and young people can meet scientists, and science at the cutting edge. Their level of knowledge differs, but the curiosity is the same&quot;, said Stefan Bengtsson.</div></div> <div><br /></div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div><div><font color="#212121"><span style="font-size:16px"><b>Designed together with schoolkids</b></span></font></div> <div><span style="color:rgb(33, 33, 33);background-color:initial"><br /></span></div> <div><span style="color:rgb(33, 33, 33);background-color:initial">In addition to the </span><span style="color:rgb(33, 33, 33);background-color:initial">science </span><span style="color:rgb(33, 33, 33);background-color:initial">conduc</span><span style="color:rgb(33, 33, 33);background-color:initial">ted at </span><span style="color:rgb(33, 33, 33);background-color:initial">Onsala S</span><span style="color:rgb(33, 33, 33);background-color:initial">pace O</span><span style="color:rgb(33, 33, 33);background-color:initial">bservatory, visitors </span><span style="color:rgb(33, 33, 33);background-color:initial">are also given the opportunity to experience</span><span style="color:rgb(33, 33, 33);background-color:initial"> </span><span style="color:rgb(33, 33, 33);background-color:initial">space-related</span><span style="color:rgb(33, 33, 33);background-color:initial"> </span><span style="color:rgb(33, 33, 33);background-color:initial">technology and re</span><span style="color:rgb(33, 33, 33);background-color:initial">search </span><span style="color:rgb(33, 33, 33);background-color:initial">conducted at other parts of Chalmers.</span><br /></div> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P"><span><br /></span></p> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P"><span>On site during the opening, 21 school children participated from two schools that had been involved in developing the content of the new exhibition, Lövgärdesskolan in northern Gothenburg and Kollaskolan in Kungsbacka.

The study’s findings narrow down this range to 6.4 to 8.8 million hectares per year and helps explain the uncertainty in the numbers.</span></div> <h3 class="chalmersElement-H3">Several reasons why land is deforested &quot;for nothing&quot;</h3> <div>“A big piece of the puzzle is just how much deforestation is ‘for nothing’” observed Prof. Patrick Meyfroidt from UCLouvain and F.R.S.-FNRS in Belgium. “While agriculture is the ultimate driver, forests and other ecosystems are often cleared for land speculation that never materialised, projects that were abandoned or ill-conceived, land that proved unsuitable for cultivation, as well as due to fires that spread into forests neighboring cleared areas”.</div> <div><br /></div> <div>Understanding the significance of these drivers is key for policy makers – whether in consumer markets such as the European Union’s recently proposed due diligence legislation for “deforestation free products”, private sector initiatives for specific commodities, or for rural development policy in producer countries.</div> <div><br /></div> <div>The study makes clear that a handful of commodities are responsible for the majority of deforestation linked to actively producing agricultural land – well over half of which is linked to pasture, soy and palm oil alone. But it also calls out the shortcomings of sector-specific initiatives that are limited in their ability to deal with indirect impacts.</div> <div><br /></div> <div><span style="color:rgb(33, 33, 33);font-family:inherit;font-size:16px;font-weight:600;background-color:initial">New import measures a major step forward​</span><br /></div> <div>“Sector specific initiatives to combat deforestation can be invaluable, and new measures to prohibit imports of commodities linked to deforestation in consumer markets, such as those under negotiation in the EU, UK and USA represent a major step forward from largely voluntary efforts to combat deforestation to date,'' said Dr. Toby Gardner of the Stockholm Environment Institute and Director of the supply chain transparency initiative, Trase.</div> <div><br /></div> <div>“But as our study shows, strengthening forest and land-use governance in producer countries has to be the ultimate goal of any policy response. Supply chain and demand-side measures must be designed in a way that also tackles the underlying and indirect ways in which agriculture is linked to deforestation. They need to drive improvements in sustainable rural development, otherwise we can expect to see deforestation rates remaining stubbornly high in many places,” Dr. Gardner added.</div> <div><br /></div></div> <div><span style="background-color:initial">The study’s findings point to the need for supply chain interventions to go beyond a focus on specific commodities and risk management, to help drive genuine partnerships between producer and consumer markets and governments. This needs to include strong incentive-based measures that make sustainable agriculture economically attractive, while disincentivising further conversion of native vegetation and supporting the most vulnerable smallholder farmers. The authors say this should include a stronger focus on domestic markets, often the biggest drivers of demand for many commodities, including beef, and a strengthening of partnerships between companies, governments and civil society in producer jurisdictions.</span></div> <div><br /></div> <div><span style="background-color:initial"> <h3 class="chalmersElement-H3">Several critical evidence gaps</h3> <div>Finally, the study highlights three critical gaps where a stronger evidence base is needed to better target efforts to reduce deforestation; </div> <div><img src="/SiteCollectionImages/Institutioner/SEE/Profilbilder/Martin_Persson_2022.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" /><br />“The first is that without a globally and temporally consistent data product on deforestation we cannot be confident about overall trends in conversion. The second is that except for oil palm and soy, we lack data on the coverage and expansion of specific commodities to know which are more important, with our understanding of global pasture and grazing lands being especially dire. The third is that we know comparatively very little indeed about tropical dry forests, and forests in Africa”, said Professor Martin Persson of Chalmers University of Technology. </div> <div><br /></div> <div>“What is most worrying, given the urgency of the crisis”, added Prof. Persson, “is that each of these evidence gaps pose significant barriers to our ability to drive down deforestation in the most effective way – by knowing where the problems are concentrated, and understanding the success of efforts to date”.</div> <div><br /></div> <div>Despite these knowledge gaps and remaining uncertainties, the study stresses that a step-change in efforts is urgently needed to effectively tackle and curb deforestation and conversion of other ecosystems and to foster sustainable rural development. The Glasgow Declaration on Forests recognised the importance of jointly addressing the crises of climate and biodiversity loss and set a new level of ambition for tackling deforestation and promoting sustainable agriculture. The authors of this new study say it is paramount that we begin to see individual countries and policymakers prioritise the realisation of this ambition.</div></span></div> <div><br /></div> <div><span style="color:rgb(33, 33, 33);font-family:inherit;font-size:16px;font-weight:600;background-color:initial">More info about the research </span><br /><span style="background-color:initial"></span></div> <div><a href="https://www.science.org/doi/10.1126/science.abm9267">The research article Disentangling the numbers behind agriculture-driven tropical deforestation</a> was published in Science 377, 9 September 2022.

Henrik Thunman and his research team want to focus on an important resource that often goes up in smoke today: the carbon atoms in our waste, which are currently incinerated or end up in landfills instead of being recycled. This is made possible with technologies targeting the carbon contained in plastic, paper and wood wastes, with or without food residues, to create a raw material for the production of plastics with the same variety and quality as those currently produced from fossil raw materials. </div> <div><br /></div> <div><strong>Just like nature </strong></div> <div>Current plastic recycling methods are able to replace no more than 15-20% of the fossil raw material needed to meet society’s demand for plastic. The advanced methods proposed by the researchers are based on thermochemical technologies and involve the waste being heated to 600-800 degrees Celsius. The waste then turns into a gas, which after the addition of hydrogen can replace the building blocks of plastics. Using this recycling method could decouple new plastic products from the supply of new fossil raw materials.</div> <div>The researchers behind the study are developing a thermochemical recycling method that produces a gas which then can be used as a raw material in the same factories in which plastic products are currently being made from fossil oil or gas. Different types of waste, such as old plastic products and paper cups, with or without food residues, are put into the reactors at the Chalmers Power Central.</div> <div><br /></div> <div>“The key to more extensive recycling is to look at residual waste in a whole new way: as a raw material full of useful carbon atoms. The waste then acquires value, and you can create economic structures to collect and use the material as a raw material worldwide,” says Henrik Thunman. </div> <div>The principle of the process is inspired by the natural carbon cycle. Plants are broken down into carbon dioxide when they wither, and carbon dioxide, using the sun as an energy source and photosynthesis, then creates new plants. </div> <div><span style="background-color:initial">“H</span><span style="background-color:initial">owever, our technology differs from the way it works in nature because we don’t have to take the detour via the atmosphere to circulate the carbon in the form of carbon dioxide.

The limiting factor is battery capacity, which is not enough to power ships and ferries across longer distances. But now researchers at <strong>Chalmers and the marine research facility SSPA</strong> have succeeded in developing a method that can make the shipping industry significantly greener in the future. The focus is on hydrofoils that, like wings, lift the boat’s hull above the surface of the water and allow the boat to travel with considerably less water resistance. A technology that in recent years has revolutionised sailing, by which hydrofoils make elite sailors' boats fly over the surface of the water at a very high speed. <br /></span><div>The researchers at Chalmers and SSPA now want to enable the sailboats' hydrofoil principle to be used on larger passenger ferries as well, resulting in enormous benefits for the climate. <br /><img src="/SiteCollectionImages/Institutioner/M2/Nyheter/Arash%20200x200.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px 15px" /><br /><span style="background-color:initial"><strong>&quot;</strong></span><span style="background-color:initial"><strong>The electrification of ferries cannot be done</strong> without drastically reducing their water resistance.

Using the data collected from the experiments, the team has developed and validated a method to simulate and predict with great precision how the hydrofoil would behave under a variety of conditions. The method is unique of its kind and can now be used to develop the design of hydrofoils for electric powered hydrofoil ferries.<br /></div> <div><br /><img src="/SiteCollectionImages/Institutioner/M2/Nyheter/Laura%20200x200.jpg" class="chalmersPosition-FloatLeft" alt="" style="margin:5px 15px" />The study was conducted in collaboration with the research facility SSPA – one of only a few of its kind in the world – where <strong>Laura Marimon Giovannetti</strong> works as a researcher and project manager. She is the lead author of the study and has herself competed at the elite level for both the British and Italian national sailing teams. Today she is a research and development adviser to Sweden's Olympic committee and the Swedish national team with her sights set on helping the team win more medals at the Olympics in 2024. Marimon Giovannetti sees many possibilities for the unique measurement method developed by the team: </div> <div><br /></div> <div><div><strong>&quot;At the Americas Cup in San Francisco Bay in 2013</strong>, it was the first time we saw a 72-foot sailing boat learning how to “fly” using hydrofoils during the competition.

With this new method and knowledge we are able to bring together a range of different branches of engineering – naval architecture, advanced materials and aeronautics as well as renewable energy.&quot;</div></div> <h2 class="chalmersElement-H2">Paving the way for hydrofoils on electric ferries </h2> <div>Hydrofoil technology is not in itself a novelty, but was developed as early as the 60s and 70s. Back then the focus was on getting boats to travel at as fast as possible and the hydrofoils were made of steel, a heavy material with higher maintenance costs. Today's modern hydrofoils are made of carbon fibre, a much lighter and stiffer material that can maintain its rigidity even under high loads – and can be tailored to the expected loads. Part of the research project was therefore to fully understand how a carbon fibre structure behaves underwater during different operational conditions. The research team's method developed in association with modern technology is now paving the way for the use of carbon fibre hydrofoils on larger passenger ships that can travel in a safe, controlled and climate-friendly way even at low speeds. <br /><br /></div> <div><strong>&quot;You want the foil to be as efficient as possible</strong>, which means carrying as much weight as possible at as low a speed as possible with the least resistance.

These are advice from three Chalmers researchers and members of the newly formed climate council who will follow and review the City of Gothenburg's work towards reducing the climate footprint by 2030.</b></p><div>The decision to establish at climate council in Gothenburg was made by the city's climate and environment committee, on May 24, 2022. The council will analyze how the climate goals in the city's environmental and climate program can be achieved in a cost-effective way, by proposing and evaluating various measures. The council has seven members, three of them from Chalmers. <br /></div> <div><br /></div> ​One of Gothenburg's major challenges is housing, and <strong>Holger Wallbaum</strong>, Professor in Sustainable Building at the Department of Architecture and Civil Engineering, thinks that the City of Gothenburg needs to focus both on speeding up planning and construction processes to meet the demand for new housing for the growing population, and on a climate-friendly and economically sustainable renovation of the existing building stock. The latter is closely linked to his research group's work to find solutions to the housing challenges by providing data, tools, methods and innovations for a more sustainable built environment.    <br /><br />The building materials used have an environmental impact throughout their full life cycle, and Holger Wallbaum therefore believes that we must plan, build, operate and maintain our buildings differently to achieve the very ambitious goals of being fossil-free and carbon neutral in the near future.    <br /><br /><div>– Extra efforts need to be made to reduce the climate impact from the building methods used and from load-bearing structures and building materials. If we are to achieve the goals, efforts will be required from all actors involved, from academia to authorities and companies and also at the individual level. The challenges are great, but they come with many opportunities if we pursue the necessary transformation of the built environment in a holistic way, says Holger Wallbaum.   <br /><br /><strong>Frances Sprei</strong> is an Associate Professor at the Department of Space, Earth and Environment, Physical Resource Theory. Her research assesses different personal mobility options, such as alternative fueled vehicles and electric vehicles, as well as innovative mobility forms such as car sharing and ride sharing. She thinks that that there are many possibilities to decrease emissions from the transport sector.     <br /><br />– The transport sector accounts for a large part of emissions. This is also a sector where the city of Gothenburg has some control over both when it comes to promoting electrification and reducing car dependence, says Frances Sprei. <br /><br /><strong>Fredrik Hedenus</strong>, Professor, also at the Physical Resource Theory at the Department of Space, Earth and Environment, researches strategies to reduce the climate impact of energy and food production. The research focuses on both policy instruments and the effects of various technical and behavioral measures.

By identifying historical precedents of rapid transitions and comparing these to the scale and speed of changes society needs to meet climate targets, we are able to identify the areas where change is most feasible. </span></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial">I applied to the Young Academy of Sweden because I want to develop Sweden's system for attracting research talent and developing science by identifying the areas where we are already world leaders, as well as those where we can learn from other countries.

Given that living in impoverished communities can trap people in cycles of deprivation (‘poverty traps’), major development actors such as China and the World Bank have deployed a stream of projects to break these cycles (‘poverty targeting’). However, as scholars are held back by a data challenge, research has up until now been unable to answer fundamental questions such as whether poverty traps exist, and to evaluate what extent interventions can release communities from such traps </div> <div><br /></div> <div>I am leading the <a href="https://liu.se/en/research/global-lab-ai">AI and Global Development Lab​</a> to identify to what extent African communities are trapped in poverty and examine how competing development programs can alter these communities’ prospects to free themselves from deprivation. Our Lab has the following objectives: (i) train image recognition algorithms—a form of AI—to identify local poverty from satellite images, 1984-2020; (ii) use these data to analyze how development actors affect African communities; (iii) use mixed methods to develop theories of the varieties of poverty traps; (iv), develop an R package, PovertyMachine, that will produce poverty estimates from new satellite images—ensuring that our innovations will benefit poverty research. </div> <div><br /></div> <div>I want to be a part of the Young Academy of Sweden <span style="background-color:initial">Because the academy offers a unique opportunity to change, improve, and refine Swedish universities and their position globally”</span><span style="background-color:initial">. </span></div></div> <div> </div> <h3 class="chalmersElement-H3">About the Young Academy of Sweden  </h3> <h3 class="chalmersElement-H3"> </h3> <div>The Young Academy of Sweden is a multidisciplinary academy, comprising a selection of the best young researchers in Sweden – an independent platform that gives young researchers a strong voice in the research policy debate and is working on raising the profile of research for young people. </div> <div><br /></div> <div><span style="background-color:initial">Young academies exist in over 30 countries and Sweden's Young Academy works with the other young academies at Nordic, European and global levels. </span><span style="background-color:initial">. </span></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial"><div><a href="https://www.sverigesungaakademi.se/en-GB/1.html">Read more about the Young Academy of Sweden and its new members</a>. </div> <div><span style="background-color:initial"><font color="#1166aa"><b><a href="/en/research/our-scientists/Pages/The-Young-Academy-of-Sweden.aspx">Find all Chalmers researchers who are or have been members of the Young Academy of Sweden</a></b></font></span>.</div></span></div>Tue, 24 May 2022 00:00:00 +0200
