Prof. Dr. Johan Rockström
Johan Rockström is Director of the Potsdam Institute for Climate Impact Research, Professor at the Institute of Earth and Environmental Science at Potsdam University, and Professor in Water Systems and Global Sustainability at Stockholm University.
Rockström gained international recognition with the development of the Planetary Boundaries
framework, which has since become a standard of sustainability science. He is deeply involved in research activities covering a range of topics related to the Earth System and global sustainability in the Anthropocene, with the overarching research question: “What is the safe operating space for Humanity's future on Earth, and which sustainable transformations that can take us there?” Rockström’s research creates considerable impact. For example, he received the prestigious European Research Council (ERC) Advanced Grant, and is ranked as one of the most influential and most-cited scientists in the world by Clarivate Analytics.
In addition to his research endeavors, which have been widely used to guide policy,
Rockström provided strategic scientific guidance as a member of the European Commission’s Expert Group ‘Mission Board for Adaptation to Climate Change, including Societal Transformation’ and various scientific academies, including the Royal Swedish Academy of Sciences and the German National Academy of Sciences Leopoldina. He regularly acts as a speaker to high-level international meetings and organisations, such as the World Economic Forum (WEF), the General Assembly of the United Nations (UNGA), the United Nations Sustainable Development Solutions Network (SDSN) and the United Nations Framework Convention on Climate Change Conferences (UNFCCC). Moreover, he is the Chief Scientist of Conservation International, as well as chairing the advisory board for the EAT Initiative on Health, Food and Sustainability, the Earth League, Future Earth (co-chair), the United Nations Sustainable Development Solutions Network (SDSN) and the Earth Commission.
Rockström’s work has been recognized with accolades, the most recent of which include the Prince Albert II of Monaco Climate Change Award (2020), the Hillary Laureate by the Hillary Institute of International Leadership (2017), the French distinction Knight of the Legion of Honour (2016), the German Environmental Award (2015) and the International Cosmos Prize (2015). Before becoming Director of the Potsdam Institute of Climate Impact Research, Rockström founded the Stockholm Resilience Centre at Stockholm University and was Executive Director at the Stockholm Environment Institute. He obtained a Master of Science (MSc) at the Swedish University of Agricultural Sciences, a Diplôme d’Agronomie Approfondie (DAA) at Institut National Agronomique Paris-Grignon, a Licentiate of Philosophy (PhLic) at Stockholm University, and completed a doctorate (PhD) in Natural Resources Management at Stockholm University.
A safe and just future for humanity on Earth
Science is today clear, we are facing multiple and interacting global environmental changes that together threaten the stability of the Earth system, and thereby the basis for world development. Six of nine planetary boundaries are today transgressed, providing ample evidence of a coupled global biosphere and climate crisis. The consequences are not only felt as rising frequency and amplitude of extreme events, causing massive social and economic loss and damage. We are rapidly approaching biophysical tipping points which, if crossed, will cause irreversible and self-amplifying impacts. Two key conclusions arise from the latest Earth system science with regards to climate safety. First, that 1.5°C is not a goal or target, it is a biophysical limit. Cross it, and we are likely to trigger multiple tipping points in the Earth system. Second, there is no safe landing for humanity, with regards to a manageable climate, unless we also bend the curves and return back to a safe operating space within Planetary boundaries, for land, water, biogeochemical flows and biodiversity. The Earth system, in a healthy state, has a remarkably high resilience, but we are seeing ample signs of cracks in the buffering capacity of the biosphere, and need to urgently act on all planetary boundary transgressions. This calls for setting scientific targets for a safe operating space on Earth, to keep the Earth system in a Holocene-like inter-glacial state. The talk also summarizes the multiple crisis we are facing – the climate crisis, the loss of biodiversity, the coronavirus pandemic, the energy crisis etc. A first attempt, based on the work of the Earth Commission, on defining safe and just Earth system boundaries is presented, as well as the "Earth for All" scenario analyses of pathways towards attaining the SDGs within Planetary Boundaries.

Emily Boyd was previously a professor in resilience geography (2013-2016) and a reader in environment and development (2011-2013) at University of Reading. She has previously had a number of leadership roles as research division lead for global development at University of Reading, including departmental impact lead and research director in the School of Archaeology, Geography and Environmental Sciences (SAGES), Reading University. Her past research includes fieldwork in Mozambique where she was co-lead on a UN award-winning research project with informal settlements in Maputo, and on resilience and food security among coffee and cocoa producers in Ethiopia and Ghana as part of an ESPA, NERC-ESRC-DFID funded consortium project.
Pivoting between loss and hope in governing a just future for humanity
Climate justice (CJ) is experiencing a renaissance in the context of large-scale loss and damage (economic and non-economic) amid growing vulnerability among people across all corners of the planet. Globally societies are now confronted with climate loss and damage compounded by existing social vulnerabilities and multiple crises. These risks are projected to continue into the future. There is no question that loss and damage is a complex agenda in terms of who is responsible and who pays for creating a safe and fair future under climate change. Loss is critically about the limits to adaptation and results in costs to societies both in terms of lost dollars and negative consequences for cultures from territory and cultural heritage loss for example resulting from sea level rise. By no means is it easy to define, measure or govern these limits, as the talk will demonstrate. However, climate justice is also imbued with hope. Researchers demonstrate resurgence of ideals on redistribution of resources, fair procedures, and recognition of rights by mechanisms of inclusion and accountability. CJ also introduces hope through new (if not complex) ideas on compensation, degrowth, and vulnerability as an opportunity for agency. In evidence of this, mobilisation among civil society and youth has emerged in recent years, parallel with the science of attribution, and numerous court cases and climate litigation. Since climate change is longer merely abstract idea for some, but a growing reality for many, communities and leaders will mobilise over the coming year to define a new loss and damage financing regime for the very purpose of compensating the most vulnerable. It is an unprecedented and daunting task. It raises questions of what is development today? Who is vulnerable? And how are people on the frontline experiencing the effects of loss? Pivoting loss and hope are essential for collective willingness and restructuring to create new conditions for just transformations.
Claudia Teutschbein is an Associate Professor in Hydrology at the Department of Earth Sciences, Uppsala University, Sweden.

Water in an interconnected world: A key enabler to reach energy and food security?
The availability and sustainable use of water, energy and food resources are essential for human wellbeing and development. The complex and interdependent connections between the supply and demand for these resources form an interconnected worldwide network, referred to as the water-energy-food nexus. This nexus is continuously evolving due to ongoing changes in population, environment, climate, land, political and socio-economic conditions. Abrupt alterations of these conditions (e.g., rapid climate change, a sudden policy change) may lead to unexpected non-linear impacts, which can threaten global economy and resource security. This presentation highlights the importance of taking a holistic systems perspective and showcases evidence of stress on our life-sustaining water, energy and food resources. With a focus on water as one of the most crucial resources for human civilization, societal progress and the achievement of the United Nations Sustainable Development Goals, the consequences of too little and too much water in an increasingly connected world will be discussed.

Abstract: Soft, Skin-Interfaced Electronic and Microfluidic Systems.
The skin is mechanically soft and curved; modern electronic and microfluidic technologies are rigid and planar. Eliminating this profound mismatch in physical properties will create vast
opportunities in man-made systems that can naturally integrate with the epidermis, for diagnostic, therapeutic or sensory function with important, unique capabilities relevant to fitness/wellness, sports performance, clinical healthcare and virtual reality environments.
Over the last decade, a convergence of new concepts in materials science, mechanical engineering, electrical engineering and advanced manufacturing has led to the emergence of diverse, novel classes of 'biocompatible' electronic and microfluidic systems with skin-like physical properties. This talk describes the key ideas and presents some of the most recent device examples, including (1) wireless, battery-free electronic 'tattoos', with applications in continuous monitoring of vital signs in maternal, fetal, neonatal and pediatric populations, including active deployments in the most advanced hospitals in the US and remote clinics in multiple countries in Africa, (2) microfluidic platforms that can capture, manipulate and perform biomarker analysis on microliter volumes of sweat, with applications in cystic fibrosis and nutritional monitoring.

Abstract: Fat-Intra Body Communication: A new paradigm for intra-body communication technology enabling reinstatement of lost functionalities in human. Intra body communication has been researched quite extensively for past couple of decades to serve the needs in real time monitoring, drug delivery, sensing for pre-emptive measures and to provide better quality of living to the population. The applications are not just limited to health care but also span the areas of recreation, sports and information technology. A handful of intra body, more specifically human body centric (HBC) communication modalities have been developed so far namely galvanic, capacitive and inductive methods. Human body or part is used as a communication channel in these technologies. Though they offer the possibility to connect devices and transfer data wirelessly from one part of the body to the other they suffer from one common drawback which is the low bandwidth hence lower data rates. Radio frequency communication has been regarded until recently as an improbable candidate for extensive HBC applications. In 2016 the Asan et. al from the Microwaves in Medical Engineering Group, Uppsala University, Sweden published her first paper on the feasibility using the adipose tissue to transmit Microwave signals inside the body with significantly low loss(2dB/cm) . Since then a number of articles have been published on different aspects of fat – intra-body communication (Fat-IBC) [2-6]. Considering the human anatomy, the fat tissue is found to be sandwiched between denser tissues such as skin and muscle. As it is known that the fat due to its very low water content has low permittivity and losses while muscle and skin do have almost an order of magnitude high permittivity and losses which is three to four times that of fat. This creates a natural wave guiding structure which we can utilize to transmit microwave signals at ISM frequencies. Fat- IBC pushes
further the current limits in intra-body data transfer by providing a higher bandwidth and enabling better power management to ensure longer implanted battery life. Fat channel communication will also help substantially the development of artificial limbs which require transfer of high-volume electrophysiological data, wirelessly.

Combining Stem Cell and Device Engineering for In vitro Models of Human Physiology
Mammalian cell in vitro studies have traditionally had poor translation to human in vivo processes and treatment outcomes. The low resemblance between classical cell culture—a monolayer, static, monoculture of cell lines and the dynamic, three-dimensional, and multicellular in vivo environment is a major reason for this gap. The demand to accurately model human physiology and pathophysiology has, however, risen with the insights into inter-species differences in animal models and with the increasing development of human-specific treatments.
Engineered human microfluidic Organ-on-Chip models have emerged as a promising new pre-clinical technology to fill this demand. In Organ-on-Chips, cells are cultured in connected microcompartments and with perfusion. Recent studies have shown that physiological processes related to pharmacokinetics and pharmacodynamics (PK/PD) as well as toxicology can be replicated in these systems. We have developed a 10-organ Organ Chip automated platform to recapitulate a full human Body-on-Chip with physiological vascular coupling to combine multiple organ models (Herland Nature Biomedical Engineering 2020). This Body-on-Chip system allowed studies of intestinal (oral) uptake, intravenous (IV) injection, first-pass metabolism and excretion, organ-specific responses, and accurate in vitro-to-in vivo extrapolation (IVIVE). We are currently developing these systems from three perspectives: first, to increase human physiological relevance through stem cell engineering and relevant three-dimensional microenvironment, second, to incorporate non-disruptive real-time monitoring of cellular functions, and third, to make them user-friendly and cost-effective (Kavand, Advanced Materials 2022). Our specific focus is the neurovascular unit (NVU), the restrictive barrier that lines the capillaries that course through the brain and spinal cord. We are using micro-engineering to create vascular-mimicking, fluidic Organ-on-Chip models of NVU. These models are populated with human pluripotent stem cell-derived vascular and neural cells. The design and material of the NVU-on-Chip have been tailored to study barrier penetration of small drugs and biopharmaceuticals, as well as cellular interactions and inflammatory responses in real-time (Matthiasen Small 2021).
