New grant to increase sustainable seafood production and consumption
Beijer Institute researcher Max Troell and colleagues have been granted SEK 10 million in funding by the Swedish research council Formas for research on how to sustainably increase production and consumption of seafood in Sweden.
Healthy, but what about sustainable?
Producing healthy food for a growing world population without increasing the pressure on the planet’s ecosystems is one of the greatest challenges of our time. Seafood could play an increasingly important role for global food supply since it is both healthy and comparatively resource efficient to produce. At the same time, capture fisheries and aquaculture production can cause harm to the environment, for example from the use of damaging fishing gear or by overuse of antibiotics in fish farms.
“These are problems that need to be addressed if the seafood sector is to reach its full potential,” says project leader Max Troell. “Within this new project we aim to investigate environmental performance of some innovative Swedish aquaculture methods, for instance farms that integrate aquaculture and agriculture, growing their own fish feed and using byproducts from the aquaculture on the fields. Or closed recirculating systems where the seafood is grown on tanks on land. We will quantify impacts such as greenhouse gas emission, nutrient emission, acidification and land-use, ” Troell explains. Project partners in Gothenburg and Canada will also study fishing practices aimed to minimize bycatch.
How to change habits
Moreover, the interdisciplinary team of researchers will look at what drives or hinders people to eat more sustainable and healthy seafood. With experimental behavioral studies they will explore what makes customers choose sustainable alternatives and they will also study what role eco-certification, such as MSC, ASC and similar labels, as well as other policy measures play.
Knowledge that can stimulate change
The project named SEACHANGE is teaming up with public and private partners to maximize value for society and the findings will be used to improve existing sea food guides (WWF) aimed at consumers, retailers and producers. Although this project have a Swedish focus, a broader impact can be foreseen:
“Increased knowledge on effective mechanisms in improving the environmental performance of fisheries and aquaculture will be of great importance for stimulating change, both in Sweden and globally,” concludes team project member Patrik Henriksson, Stockholm Resilience Centre and the Beijer Institute.

EAT-Lancet commission - new solutions for our global food system
Obesity rates are rising in nearly every country in the world and one in three people on Earth suffers from some form of malnutrition. Overconsumption of unhealthy food is increasing, at the expense of human health and the resilience of ecosystems.
To address this, a new EAT-Lancet commission has been launched to tackle the global food system’s role in malnutrition and global change. The commission will investigate the connections between diet, human health and the state of the planet to provide a basis for new evidence-based policies. This global assessment, due for completion in 2017, will be the first systematic analysis of the global food system and will help policy makers by providing a roadmap for how transformation of the food system can help in attaining the UN Sustainable Development Goals (SDGs) and meeting the terms of the Paris Climate Agreement.
The EAT-Lancet Commission, which consists of 20 world-renowned scientists, was launched in Stockholm on 11-12 June prior to the 2016 EAT Stockholm Food Forum. It is co-chaired by Professor Johan Rockström, SRC (and Professor Walter Willet, Harvard School of Public Health. Beijer researchers Therese Lindahl and Max Troell belong to the team of supporting co-authors.

Call for Sweden to take the lead for sustainable seafood
Fish matters - but how ?
That fish is important for many poor is a statement that few would question. Within the developing community fish is generally upheld as important for both food security and poverty reduction in many countries around the world. But on what research is this narrative based and what is the scientific quality and consistency of supporting literature?
A recent study published in World Development set out to evaluate the existing evidence of how and to what extent capture fisheries and aquaculture contribute to improving nutrition, food security, and economic growth. This review is co-authored by Beijer Institute researcher Max Troell, together with an international team of scientists led by Chris Béné at the International Center for Tropical Agriculture (CIAT/CGIAR). It aims to assess the scientific quality and consistency of existing literature focusing on fisheries link to food security and poverty, as well as identifying and discussing inconsistencies. The study covered 202 academic research documents from the period 2003- 2014 with a focus on low and middle income countries.
Missing pieces in the picture
Overall the review identified quite a notable variation in terms of scientific quality and methodological rigour through the 202 studies.
“There is no doubt that fisheries can contribute to nutrition and food security, but the links between capture fisheries/aquaculture and poverty alleviation are complex and still to some extent unclear” - says Max Troell.
The analysis showed that national and household level studies on fisheries’ contributions to poverty alleviation lack good conceptual models and produce inconsistent results. For aquaculture this was different as national and household studies focused mainly on export value chains and used diverse approaches.
Some degree of poverty alleviation and possibly other positive outcomes for fish farmers was identified, but these outcomes depended to a large extent on the specific farming on whether the aquaculture practices had come from within communities or as a result of development assistance interventions.
“Importantly the evaluation reveals that evidence-based research and policy narratives are often disconnected” says lead author Chris Béné who further points out that this may lead to questionable policy recommendations.
Six steps to success
The study identified six key knowledge gaps for policy-makers, practitioners and researchers:
1. Key components of capture fisheries and aquaculture are often not accounted for or miscounted in national statistics. Few socio-economic studies have looked at the impact of fisheries or aquaculture on low-income households.
2. Gender relations as well as health and safety need to be addressed in the fisheries sector. Women are often under-represented in statistics, and health and safety issues are often neglected.
3. Poverty is not clearly conceptualised, articulated or measured in fisheries and aquaculture studies. For example recognition is needed that addressing fisheries management issues in developing countries is not the same as addressing the issue per se.
4. For aquaculture many questions remain concerning who benefits and at what cost to whom. The causal effect between aquaculture development, food security and poverty alleviation is not necessarily a straightforward one.
5. Problems persist in the area of nutrition and determining the impact of fish availability on micronutrient status and other measurables.
6. There is an urgent need for more studies to explore the local-level impacts of global drivers of food security such as urbanisation and climate change. For example, lack of reliable data on small-scale fisheries risk complicating the uncertainty induced by climate change on the dynamics of fish stocks.

Valuing and Designing Payment Systems for Ecosystem Services
A short course held in conjunction with EAERE 2016 June 21-22, 2016, in Zurich, Switzerland
Payment systems for ecosystem services (PES) have expanded rapidly in the decade since the publication of the Millennium Ecosystem Assessment. Most PES systems pertain to regulating services, and they aim to create incentives to conserve ecosystems that are presumed to supply such services. Examples include watershed payment programs that are intended to improve water quality or reduce floods and droughts by conserving forests in upland regions. Despite the increasing popularity of PES systems, the value of the services that these systems actually supply in practice remains poorly understood, and the design of the systems faces a number of economic challenges that can impede their effectiveness.
This two-day course will cover both of these issues: the valuation of regulating ecosystem services, and the design of PES systems to supply those services. It will involve a mix of lectures and interactive exercises. The valuation sessions will include hands-on econometric exercises that use the statistical package Stata. The sessions on PES design will include group discussions and presentations. The primary instructors in the course are: Prof Nick Hanley (University of St Andrews, Scotland, UK) and Prof. Jeffrey R. Vincent (Duke University, North Carolina, USA)
Seminar: People and Sulfur: The Forgotten Element Cycle
Tuesday 24 November 2015, 13.00-16.30, Royal Swedish Academy of Sciences
The carbon cycle has taken centre stage as a global element cycle in the run-up to the Paris climate conference and beyond. Even the nitrogen and phosphorus cycles get plenty of attention in their role as critical elements for food production, as well as pollutants that can eutrophy freshwater systems and the coastal zone. But in many ways, the global sulfur cycle is just as important.
It was at the centre of the acid rain problem that afflicted Europe and eastern North America a few decades ago. For many years, sulfur compounds have been central to the role of aerosols in local and regional air pollution, most notably as a feature that threatens the stability of South Asian monsoon system and that drives health impacts through urban air pollution.
But the sulfur cycle is also crucial in the functioning of terrestrial and marine ecosystems. In fact, one of the key feed-back mechanisms that operates in the global climate system, involving marine microorganisms and clouds, could be coupled to the sulfur cycle.This seminar explores the global sulfur cycle and its complex relationship with people with 2015 Volvo Environment Prize laureate Professor Henning Rodhe and colleagues.
Henning Rodhe is Professor of Chemical Meteorology at Stockholm University. His pioneering work explains how gases and particles are transported and deposited and how they affect climate, ecosystems and human health. Henning Rodhe’s research can be described to some extent as detective work, combining data collection with scientific theories and fieldwork. He has demonstrated that long-range transportation, as for mercury and radioactive fallout, is more widespread than previously believed. The atmosphere can carry particles a very long way, and the fallout and environmental problems can occur where not expected.

A new landscape of global crises
In the past crises were often local and isolated. They left surrounding ecosystems and societies largely unaffected. This made aid and governance work easier. Today, crises are becoming more global in reach affecting more people and systems at the same time.
In a recent study in Ecology and Society a framework is proposed to identify the causes, processes and outcomes of multiple interconnected crises, which the authors term "synchronous failure”. The study was led by Thomas Homer-Dixon and Brian Walker and the authors team include Beijer researchers Anne-Sophie Crépin, Carl Folke and Max Troll, as well as several colleagues from the Stockholm Resilience Centre.
The framework shows how several stressors together can cause a crisis which can rapidly spread to become global in reach.
The framework could be used as an initial guide for systematic analyses and identifying early-warning signals and measures for building social-ecological resilience. It can also support establishment of appropriate governance structures that can navigate the danger of synchronous failure.
Causes of crises
The authors argue that future crises will increasingly result from three long-term global trends: the dramatic increase in human economic activity in relation to Earth’s environment, the rapidly increasing connections across the globe, and the decreasing diversity of human cultures, institutions, practices and technologies.
These three trends create several stresses and reduce the capacity of systems to deal with disturbances. Case studies from the 2008 financial-energy and food-energy crises illustrate this.
Three processes at play
The authors identify three processes that occur in such a crisis, often simultaneously and reinforcing each other.
The first is the long fuse big bang where slow burning stresses suddenly reach a tipping point. The straw that broke the camel’s back is not a steadily increased pressure with proportional response throughout but rather a sudden shift.
The second process, simultaneous stresses, emphasizes that many stresses can act on a system simultaneously, for example drought, poverty and social conflict. The relationships and the combined effect of them are important to understand in order to predict their effect and outcome.
The third type called ramifying cascade occurs when sudden and severe disturbances spread through tightly connected networks.
"The future wellbeing of humankind depends on functioning energy, food, water, climate and financial systems. It is increasingly clear how tightly these systems are connected," says Carl Folke.
"We encourage further research on how energy, food, water, climate and financial systems are connected. This type of knowledge is important to understand our capacity to sustain these systems and learn how to deal with crises in the future.”
