What if solar energy becomes really cheap? A thought experiment on environmental problem shifting

Solving one environmental problem may often invoke or intensify another one. Such environmental problem shifting (EPS) is a neglected topic in global sustainability research. Indeed, it is difficult to study as it requires the merging of insights from various research areas. Here we identify relevant studies, and provide an illustration and guidelines for the systematic study of EPS. As a modest thought experiment to illustrate…

Aquaculture and Sustainable Seafood

Seafood brings benefits to both human health and the environment and can have an increasingly important role to play for a sustainable food future. Large variability of how different ”blue foods” contribute and relate to environmental performance, nutritional qualities and food security pose challenges for policies aiming to steer the food system towards sustainability. However, this diversity also opens up for possibilities. Seafood is important…

Sustainability of deep-sea fish species under the European Union Common Fisheries Policy

The historical expansion of fishing industries into the deep sea has been described at the global level, but corresponding patterns are less well known at other geographical scales. The International Council for the Exploration of the Sea (ICES) has stated that most deep-sea species exploited by European fishing industries are harvested outside safe biological limits. As a result, the European Union commenced regulating exploitation of…

Global aquaculture more sustainable in the last 20 years

A new study in Nature shows that the diverse aquaculture industry has made significant strides toward sustainability but also highlights necessary measures for improvement. The findings can help shape how consumers think about the seafood they buy, and inform governance strategies critical to global food and nutrition security. Twenty years ago, an analysis led by Stanford University, sparked controversy by highlighting fish farming’s damage to…

Governance, Technology
and Complexity

The speed and scope of climate, environmental, technological and socio-economic change pose serious challenges to the problem-solving capacities of norms, institutions and legal systems world-wide. This is exacerbated by the fact that, due to globalisation and technological change, the world can be viewed as increasingly shaped by the behaviour of complex systems: emergence, connectivity, surprise, non-linear changes and poorly understood interactions across regions and sectors…

The Common Fisheries Policy: An enforcement problem

Marine populations in Europe are in decline due to the unsuccessful results of the Common Fisheries Policy. By combining data of scientific recommendations from ICES, TACs approved and reported landings with an age-structured model, the objectives of this paper are to investigate the level of compliance of the TAC regulation, and the level of enforcement and its economic impact on fishery resources. The results presented…

Course: AI for the Planet

A free online course on how to apply AI-methods (“deep learning”) to analyze satellite images related to land use change and deforestation will bw held 2 October 2020. Our living planet and the climate system are changing rapidly. Studying these changes have become increasingly possible thanks to developments in advanced satellite imaginary. Growing volumes of image data, however, also pose difficult challenges to scientists. As…

Nobel Prize Summit “Our Planet, Our Future”

The Beijer Institute is co-organiser of the first Nobel Prize Summit “Our Planet, Our Future”, bringing together Nobel Prize laureates and other esteemed leaders in the sciences, policy, business, the youth movement, and the arts to explore actions that can be achieved this decade to put the world on a path to a more sustainable, more prosperous future for all. Across three days, 26-28 April,…

Growth and reproductive simulation of candidate shellfish species at fish cages in the Southern Mediterranean: Dynamic Energy Budget (DEB) modelling for integrated multi-trophic aquaculture

A Dynamic Energy Budget (DEB) model is used to simulate growth and reproduction of the shellfish Mytilus galloprovincialis and Crassostrea gigas in an integrated multi-trophic aquaculture (IMTA) farm scenario situated in the Southern Mediterranean (the Gulf of Castellammare, Sicily). We modelled the effect of primary production enrichment at fish cages on shellfish growth and life history traits using 4 years-hourly temperature data (01 January 2006–31…

(Un)observed scientific advice, social-ecological feedbacks and the North Sea cod stock

This paper estimates the economic value of the North Sea cod (Gadus morhua) stock under recent catch and several recovery scenarios. The research presents results on: a) what the value of catches and biomass would have been if the EU fishing fleet hadfollowed the ICES scientific recommendations (SRs) and Total Allowable Catches (TACs) in the 1986–2010 period; and b) what the value of catches and…
