Jennifer Birchfield, Water Program Director with Save the Dunes, will update the group on several news items and initiatives.
Save the Dunes in partnership with the city of Valparaiso, was recently awarded a $607,000 EPA grant to improve a large detention area located at Evans & Roosevelt in Valparaiso. The basin feeds into the Salt Creek watershed and eventually into Lake Michigan.
Birchfield said more than 500 acres of developed land drains into the 2-acre Thorgren basin after a storm. That water contains pollutants, such as lawn chemicals, oil and animal feces. The grant money will spur efforts to naturalize the basin to mimic a wetland surrounding to filter pollutants. Concrete will be replaced by a meandering waterway. Turfgrass will be replaced with native plantings that have deep roots that absorb water and pollutants.
Save the Dunes officials hope the Thorgren basin will become a model for other basins in the Lake Michigan watershed.

Climate change impacts on aquatic and marine ecosystems and associated livelihoods are growing, and the purpose of this circular is to provide a brief overview of potential impacts and details of ongoing and completed adaptation activities. Sharing examples will aid planning and development of adaptation in fisheries and aquaculture, and this compilation is intended to provide a starting point for planners, policy-makers, and practitioners who are involved in sectors related to fisheries and aquaculture around the globe. This introduction provides an overview of climate change impacts on fisheries and aquaculture. The presentation reviews potential mitigation and adaptation options for fisheries and aquaculture at various scales. This is followed by an overview of selected adaptation activities at various scales to demonstrate the types of activities underway or completed around the world, primarily in developing countries. This is not a comprehensive review of adaptation actions – there are other resources that provide more in-depth reviews of adaptation. However, this circular aims to provide examples of the kinds of adaptation activities specifically addressing fisheries and/or aquaculture.
"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet.
Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies.
By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet.
In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.

UNDERSTANDING WHAT GREEN WASHING IS!.pdfJulietMogola
Many companies today use green washing to lure the public into thinking they are conserving the environment but in real sense they are doing more harm. There have been such several cases from very big companies here in Kenya and also globally. This ranges from various sectors from manufacturing and goes to consumer products. Educating people on greenwashing will enable people to make better choices based on their analysis and not on what they see on marketing sites.

4. Historical Background
• Link between agricultural alterations and
stream nutrient concentrations
• Reasons in the past: transformation of forest
into crop fields
→ erosion + sediment input into river stream
• Reasons today: input of fertilizer
→ land use directly linked to water quality
5. Nitrogen in the Mississippi - Atchafalaya River Basin
(Goolsby et al. 2000)
6. Biogeochemical consequences
High N input leads to:
• Increased productivity
→ algal blooms
→ change in phytoplankton community
→ microbial degradation of the biomass
→ oxygen depletion and bottom water hypoxia
7. Oxygen depletion and bottom water hypoxia
→ decreased nutrient cycling and bioturbation
→ shift in biogeochemical composition of sediments and overlaying waters
→ sulfate respiration dominant
Biogeochemical consequences
8. Strong seasonal stratification
Less fresh water discharge =
● Lower surface salinity
● Less low oxygen conditions
● Reduced suspended sediment loads
● Reduced nutrient flux
● Increased water clarity across the continental shelf
Hypoxia in the Gulf of Mexico
9. Higher temperatures will increase biological processes
Higher precipitation will lead to:
• increased runoff & erosion
• increased freshwater discharge
→ strengthen stratification and worsen hypoxia
Tropical storms etc. may create temporary mixing in water column
→ destratification and re-aeration
The Impact of Climate Change
10. • Develop and implement long-term, broad-scale, and persistent efforts to reduce substantial
nutrient loads
• Nominate water and resource managers to take actions and monitor
• Working together towards a mutually satisfying equilibrium of interest, including scientists, land
managers, agriculturists, as well as citizens

Editor's Notes
As we learned during the last day anthropogenic activity has a major impact on material/element/nutrient fluxes and alters our ecosystem. This graphic gives you a great overview over the processes and the interconnection
Not only our actual activities but also climate change will have a major impact on our aquatic system. Nutrient input will not only alter sediment chemistry but also lead to bloom and affect oxidation of the water column
Environmental changes like sea level rise temperature and winds also will alter biological and physical processes, depending on area in the world. And will increase the latter named changes.
In the following we want to present you our case study about the gulf of mexico/mississippi river area and show you what influence densely populated coast and human activities can have on the ecosystem and which outlook we have to expect and how we can change it
A river-dominated delta system where the Mississippi River meets the Gulf of Mexico, in the southeastern United States.
The 7th largest river delta in the world
70 million people live within the Mississippi basin
One of the most productive farming regions in the world
produces the majority of the corn, soy-bean and wheat in the US
This slide just gives you a more detailed overview of how nutrient input in the Mississippi river was formerly influenced by human activity and how it developed until today.
Soil erosion, due to extensive agricultural land use, lead to huge amounts of nitrogen release already back between 1830 and 1850 and in the beginning of the 20th century.
Though the effects were rather minor in comparison what is happening today: you see that the use of nitrate fertilizer has a much larger impact on the water quality and changes in ecosystems (here reffered to diatom abundance at the coast) and that’s what we want to look at in more detail in the following slides
- Slide shows the long-term patterns in nitrate concentrations in the lower Mississippi River at St Francisville - Concentrations of nitrate in Mississippi River and tributaries have increased by a factor of 2-5 since 1990 - correlation between streamflow and nitrogen concentrations (graph not in slide) → indicates that it comes from non-point sources (otherwise conc would decrease with increasing streamflow due to dilution) -The large year-to-year variation in flux is caused by variations in streamflow. → high N concentrations when streamflow high. -The Higher streamflow could influence nitrate N flux in two ways. -First, the volume of flow would be larger and more nitrate N transported. -Second, the higher precipitation would leach more accumulated nitrate N from soils in the basin.The combination of higher concentrations and higher streamflow in the 1980–1996 period would produce significant increases in nitrate N flux. - Principal sources of N: nitrate due to agricultural fertilizer used for crop production like corn, soybean, or sorghum and drainage system - study also showed that ¾ of nitrogen flux from Mississippi -Atchafalaya River Basin enters the Gulf via the Mississippi River channel
-
Higher nutrient availability leads to an exponential increase in phytoplankton population. Their decay and microbial decomposition lead to high oxygen consumption which depletes the seawater of dissolved oxygen and creates hypoxic zones.
Changes in phytoplankton community can occur if a ratio of Si to N decreases which would favor non-siliceous forms of phytoplankton, such as dinoflagellates or cyanobacteria rather than diatoms.
oxygen depletion and bottom water hypoxia
Size of these areas closely related to N load (the same-sized
hypoxic area is now formed with a lower nitrate load than historically )
New chemical composition depends length and severity of hypoxia
*sulfate respiration normally dominant in the sediment now on sediment-water line
Higher PH in bottom water lower PH on top
Hypoxic waters here are distributed from shallow depths near shore to as deep as 60 m - but more typically between 5 and 30 m.
There is higher stratification in the summer because there is less river outflow and less wind
Winds lead to vertical mixing and creates upwelling of deeper oxygenated waters.
Figure: distribution of hypoxic zones by frequency of occurrence
Higher temperatures will increase biological processes (like photosynthesis and respiration)
Primary production then maybe light limited or lack of nutrients
Higher precipitation will lead to increased runoff, and ersion à higher P loss and increased flux of DIN (especially no3-) + increased freshwater discharge à higher nutrient discharge via mississipii in guld à strengthen stratification and worsen hypoxia
Role of tropical storm and hurricanes may will help to create temporary mixing in water column and therefore destratify and re-aerate
Cheap crude oil ~1950 → increased commercial production of fertilizers via haber bosch, which started at beginning of century
Lead to an significant exponential increase in nutrient emission
creation of reactive nitrogen, which has
increased by over 20 times since the
Industrial Revolution to a global production
of 187 Tg N yr–1 in 2005, drives the
changes in nitrogen loading in the last
100 years (Galloway
