    Beschreibung: According to climate models, coastal ecosystems will face an increased frequency of heat waves and increased turbidity due to terrestrial sediment run-off induced by increasing precipitation. Several studies have examined the effects of heat waves and turbidity separately, whereas this study analysed the individual effects of both stressors as well as their interaction, because stressors affect communities differently when acting in combination. Using a factorial experimental design, we simulated heat waves (22 °C and 26 °C compared to an 18 °C control) and turbidity (sediment addition). The response of the phytoplankton community was analysed for the aggregate parameters biovolume and diversity index (H′), as well as for community composition. Heat waves had a significant negative effect on biovolume, whereas turbidity tended to affect biovolume positively. Repeated measures ANOVA revealed significant interactions of heat waves and turbidity for H′ and community composition. Strong heat waves (26 °C) alleviated the otherwise positive effect of turbidity on H′, i.e. highest diversity remained in the turbid control. Diatoms gained dominance in the control and the 22 °C heat wave treatment with Cylindrotheca closterium being the successful competitor. At 26 °C this species was lost and small flagellates dominated the experimental communities. Future increases in heat wave intensity and frequency may thus induce major changes in phytoplankton community structure whereas algae might profit from increased turbidity as an additional source of nutrients.

    Beschreibung: The innovative software system "myEcoCost" enables to gather and communicate resource and environmental data for products and services in global value chains. The system has been developed in the consortium of the European research project myEcoCost and forms a basis of a new, highly automated environmental accounting system für companies and consumers. The prototype of the system, linked to financial accounting of companies, was developed and tested in close collaboration with large and small companies. This brochure gives a brief introduction to the vision linked to myEcoCost: a network formed by collaborative environmental accounting nodes collecting environmental data at each step in a product's value chains. It shows why better life cycle data are needed and how myEcoCost addresses and solves this problem. Furthermore, it presents options for a future upscaling of highly automated environmenal accounting for prodcuts and services.

    Beschreibung: "Transformative science" is a concept that delineates the new role of science for knowledge societies in the age of reflexive modernity. The paper develops the program of a transformative science, which goes beyond observing and analyzing societal transformations, but rather takes an active role in initiating and catalyzing change processes. The aim of transformative science is to achieve a deeper understanding of ongoing transformations and increased societal capacity for reflexivity with regard to these fundamental change processes. The concept of transformative science is grounded in an experimental paradigm, which has implications for (1) research, (2) education and learning, and (3) institutional structures and change in the science system. The article develops the theoretical foundations of the concept of transformative science and spells out the concrete implications in these three dimensions.

    Beschreibung: Although it is not part of what has been called the "ambition mechanism" or "ratchet mechanism", Article 6 of the Paris Agreement also has an explicit requirement to promote ambition. Article 6 specifically highlights that some Parties choose to pursue voluntary cooperation in the implementation of their nationally determined contributions to allow for higher ambition in their mitigation and adaptation actions. Despite the common purpose, the two elements have to date been discussed mostly in isolation, both in the negotiations as well as in the wider literature. This JIKO Policy Paper sets out to change this by exploring the relationship between Article 6 and the Global Stocktake.

    Beschreibung: This policy paper reviews the concept of additionality in the context of the Paris Agreement. Additionality is a key criterion that helps to maintain the environmental integrity of the Paris Agreement, especially when units created under Article 6.2 or 6.4 are used for offsetting purposes whether that is by Parties in order to meet their NDCs or whether by other entities with legal mitigation obligations. It does so by first reviewing key concepts such as offsetting, environmental integrity, and baseline. Subsequently, it explores the context of additionality under the Paris Agreement. More specifically it discusses what should be counted as the baseline for additionality demonstration. The subsequent chapter then highlights the challenges with establishing additionality, that is establishing a causal relationship between a policy intervention and a proposed activity. Finally, the Policy Paper discusses aspects of international governance with respect to additionality.

    Beschreibung: Variability in upwelling events may lead to periods of constrained food availability in the northern Benguela upwelling system (NBUS), thereby affecting the physiological state and metabolic activity of euphausiids. Most attention has so far been paid to seasonal effects but little is known about regional variability.Metabolic activity (expressed by respiration and excretion rates) and physiological state (expressed by reproductive effort and moult activity) in Euphausia hanseni were examined at different stations during austral summer (minimum upwelling) and austral winter (maximum upwelling). Overall, regional differences in physiological state, influencing metabolic activity, were greater than seasonal ones, indicating favourable conditions for growth and reproduction year-round. Higher respiration rateswere found for females in more advanced stages of sexual development.Moult stage did not affect oxygen consumption rates, however. The physiological state of E. hanseni at the time of capture may serve as ameaningful indicator of the associated hydrographic conditions in the NBUS,to be further used in eco-system analysis on seasonal or long-term time scales. A latitudinal comparison of species highlights the extraordinary physiological plasticity of euphausiids.

    Beschreibung: In early September 2014, about 4.000 scientists, activists and artists at the 4th International Conference on Degrowth sent out two messages. 1. Industrialized societies will change, either by disaster or by design. Accelerated resource exploitation and climate change can force societies into a transition. Or they swiftly develop new forms of economic, political and social organization which respect the planetary boundaries. 2. "Degrowth" has become a new social movement which translates scientific insights into cultural change, political change and social practice. Hence, the conference itself was an experiment on the potentials and limits of share economy, commoning and sufficiency. A team of young scholars and activists from different German research institutes and non-govern- mental organisations prepared the conference. The team of the Wuppertal Institute was partly involved in the preperation of the conference. Scientists from all research groups took part in the conference, presenting and discussing project results. The publication is a collection of contributions of the Wuppertal Institute to the conference and covers pivotal issues of the degrowth-debate: indicator development (Freyling & Schepelmann), working time reduction (Buhl), feminist theory (Biesecker & Winterfeld), and urban transition (Best).

    Beschreibung: This study conducted by Wuppertal Institute and Germanwatch explores how the social pillar of sustainability at the local level could be met in Concentrated Solar Power (CSP) projects. For this purpose, the authors evaluate the livelihood dimension of CSP technology based on a case study conducted on the 160 MW pilot CSP plant Nooro I in Ouarzazate, Morocco.
