To date, there is little research on personal crisis experiences of mental health professionals. The aim of this study was to explore some of the reasons for why self-disclosure is so difficult and how these difficulties may prevent productive forms of coproduction. These questions are addressed both from a psychiatrist's autoethnographic account and from the perspective of a peer worker who works in various coproductive relationships. It is shown that mental health professionals often revert to an "I-as-we", speaking of themselves as a collective and thereby reifying the boundaries between 'vulnerable users' and 'invulnerable professionals'. Ethnographic examples are given, of how these boundaries are produced by a continuous, often invisible, and powerful category work. It is discussed how the dichotomous logic of these boundaries can cause people on both sides to feel reduced to a representation of a certain species, which can take on an existential dimension. Ways out are identified for mental health professionals to self-reflexively engage with their own crisis experience in coproductive and other relationships.
Abstract. Estuaries are nutrient filters and change riverine nutrient loads before they reach coastal oceans. They have been extensively changed by anthropogenic activities like draining, deepening, and dredging to meet economic and social demand, causing significant regime changes like tidal amplifications and in some cases to hyper-turbid conditions. Furthermore, increased nutrient loads, especially nitrogen, mainly by agriculture cause coastal eutrophication. Estuaries can either act as a sink or as a source of nitrate, depending on environmental and geomorphological conditions. These factors vary along an estuary, and change nitrogen turnover in the system. Here, we investigate the factors controlling nitrogen turnover in the hyper-turbid Ems estuary (Northern Germany) that has been strongly impacted by human activities. During two research cruises in August 2014 and June 2020, we measured water column properties, dissolved inorganic nitrogen, dual stable isotopes of nitrate and dissolved nitrous oxide concentration along the estuary. Overall, the Ems estuary acts as a nitrate sink in both years. However, three distinct biogeochemical zones exist along the estuary. A strong fractionation (~ 26 ‰) of nitrate stable isotopes points towards nitrate removal via water column denitrification in the hyper-turbid Tidal River, driven by anoxic conditions in deeper water layers. In the Middle Reaches of the estuary nitrification gains in importance turning this section into a net nitrate source. The Outer Reaches are dominated by mixing with nitrate uptake in 2020. We find that the overarching control on biogeochemical nitrogen cycling, zonation and nitrous oxide production in the Ems estuary is exerted by suspended particulate matter concentrations and the linked oxygen deficits.
Purpose
Flower strips have been shown to increase insect biodiversity and improve agricultural yields through increased pollination and pest predation. Less is known about their potential to increase soil organic carbon (SOC). We aimed to investigate the biomass production and SOC sequestration potential of flower strips as a sustainable management option of temperate agricultural soils.
Methods
23 flower strips across varying soil types and climatic regions in Germany were sampled for aboveground and belowground peak biomass in order to estimate the annual carbon input to the soil. Those were used as 23 scenarios to model the potential SOC sequestration of the flower strips compared to a business-as-usual scenario for 1533 sites of the German Agricultural Soil Inventory using the RothC model.
Results
On average, flower strips sequestered 0.48 ± 0.36 Mg C ha−1 year−1 in the initial 20-year period after establishment. Converting 1 % of the total German cropland area into flower strips would thus lead to a mitigation of 0.24 Tg CO2 year−1, which equals 0.4 % of current agricultural greenhouse gas emissions in Germany.
We found a negative correlation between C sequestration rate and the number of plant species in the flower strips, mainly related to grasses outcompeting herbaceous species.
Conclusion
Flower strips are one overlooked option for increasing SOC stocks of croplands that has multiple benefits for agro-ecosystems. However, within a flower strip it might not be possible to maximise both plant biodiversity and SOC sequestration.
Abstract. Metabolic activities in estuaries, especially these of large rivers,
profoundly affect the downstream coastal biogeochemistry. Here, we unravel
the impacts of large industrial port facilities, showing that elevated
metabolic activity in the Hamburg port (Germany) increases total alkalinity
(TA) and dissolved inorganic carbon (DIC) runoff to the North Sea. The
imports of particulate inorganic carbon, particulate organic carbon, and
particulate organic nitrogen (PIC, POC, and PON) from the upstream Elbe
River can fuel up to 90 % of the TA generated in the entire estuary via
calcium carbonate (CaCO3) dissolution. The remaining at least 10 %
of TA generation can be attributed to anaerobic metabolic processes such as
denitrification of remineralized PON or other pathways. The Elbe Estuary as
a whole adds approximately 15 % to the overall DIC and TA runoff. Both
the magnitude and partitioning among these processes appear to be sensitive
to climatic and anthropogenic changes. Thus, with increased TA loads, the
coastal ocean (in particular) would act as a stronger CO2 sink,
resulting in changes to the overall coastal system's capacity to store
CO2.
