Habitat deterioration despite protection: long-term declines of littoral area of fishponds in Czech nature reserves | bioRxiv
https://www.biorxiv.org/content/10.1101/2021.12.22.473897v1

Fishponds play a key role in current pondscapes in many developed countries. Their littoral areas, supporting multiple ecosystem functions including the maintenance of aquatic and riparian biodiversity, have been adversely affected by the move shift towards more intensive aquaculture and widespread eutrophication in the middle 20th century. To counteract these changes, many fishponds received some protection, but its long-term efficiency has not been studied. Here we focus on the role of conservation status in protecting the area of littoral areas of fishponds in Czechia between the years 1950 and 2019. We found that the conservation status of these fishponds did not prevent habitat deterioration in most of the fishponds, especially during the second half of the 20th century. Moreover, we detected no significant effects of the reserve establishment year, fishpond area and conservation target on the littoral areas. This suggests that the conservation measures are insufficient across fishpond reserve types. We attribute the negative trends to persisting high fish stocks, especially of common carp, and eutrophication resulting from additional feeding, pond manuring, and ongoing nutrient inputs from the pond catchments. Sediment dredging and high grazing pressure by waterfowl in some reserves can further aggravate the situation. We conclude that effective protection of the littoral areas requires a paradigm shift towards less intensive fish stock management, more frequent summer drainage, and effective reduction of all nutrient inputs to increase the water quality. Such measures can help recover the littoral areas and the associated biota.

Premyslela jsem o tom Turowu. tezba je nelegalni, EU parlament zada Komisi, aby zasahla, .. Morawiecki na to suše, ze Turow obsluhuje elektrinou 5 procent Polaku, takze to vypinat nemuzou, nechteji a nebudou. V celem Libereckem kraji neni dost vody.

... prijde mi to jako takova prvni vlastovka toho, jak to bude fungovat v EU v budoucnu. Komise nema jak "zasahnout". EU je dobrovolny svazek na principu prerozdelovani od bohatsich k zaostavajicim a snaha koordinovat zakony. Jak rychle se to ale rozpadne v momente, kdy konkretni zakon pro konkretniho clena prestane byt vyhovujici, s tim, jak se budou zhorsovat zivotni/ekosystemove podminky. Prijde mi, ze to ma dost temnou budoucnost

Díky Deník Referendum za příležitost se znovu pohrabat v archivech, protože někdy zpětně vylezou souvislosti, které člověk nevnímal ani jako přímý účastník.
S odstupem se ukazuje, že hejtman Půta s námi všemi sehrál jedno velké divadlo. Happeningy, petice, žaloby kvůli vodě a životnímu prostředí - jenže o nic z toho celou dobu vůbec nešlo.
V článku ukazuju, že hlavní motivací krajských politiků od začátku nebylo nic jiného než snaha získat peníze na vodovody, které se spřáteleným stavebním firmám netransparentně rozdělují ve vodárnách. Malé domů.
Co na tom, že peníze od Polska vystačí na sotva třetinu staveb, které mají být do toho roku 2044 potřeba, nemluvě o tom, že vodovody vodu nezajistí.
Chtělo by se mi dodat něco ve smyslu "po nás potopa", ale spíš by sedělo "po nás poušť"...
V článku vše pečlivě ozdrojováno. Děkuju Gaby Khazalova za pečlivou editorskou pomoc

Sulfur emissions over the oceans have been reduced globally by 80% due to new regs. Shipping accounts for around 10% of total global sulfur emissions but nearly 100% over the oceans. The result is adding huge amounts of energy into the dark oceans as we lose cloud Albedo.

Much more super saturated air over the oceans due to lower energy rejection has the potential to lead to mega rainfall events over land influenced by ocean climates. Ireland and the Uk being good candidates for such events.

Global warming to date is caused by greenhouse gases, but sulfur emissions cool ~-0.5°C, hiding part of warming.

Global shipping was responsible for a large part of anthropogenic emissions of sulfur over oceans.

Partial Hegemony - Paperback - Jeff D. Colgan - Oxford University Press
https://global.oup.com/academic/product/partial-hegemony-9780197546383?q=colgan&lang=en&cc=us

The greatest peaceful transfer of wealth across borders in all of human history began in 1973 with the #OPEC oil crisis. Had huge consequences for int'l order. It is one of several key events I investigate that can teach us much about world politics writ large.

Scholars often think about hegemonic decline by looking to Thucydides or the British Empire. But we can learn a lot (more?) from how the US lost some but not all of its dominance in the 1970s over oil. That partial decline shows what the US can expect in other areas in 21st C

The book asks, how do we make sense of the noisy, turbulent world of oil politics? Using a century’s worth of history, I uncover an underlying logic of change. Lessons for three areas: 1-today’s oil politics; 2-theories of international order and hegemony; 3-climate change.

...

I argue #decolonization was a crucial, maybe *the* crucial turning point for the global oil industry. Big interdisciplinary debate about if/how decolonization “mattered”. In the oil industry, it did.

...

E.g., my analysis shows how #OPEC has consistently failed since the 1980s to function as a cartel, because it (mostly) lacks ability to punish its members, let alone other oil producers, for noncompliance. Lesson for climate pol: ability to punish and enforce is crucial.

On climate change, Paris won’t get the job done. Among other things, we need a climate club, enforced by trade measures for non-participating states (eg CBAM). Kudos to @paulkrugman @NatKeohane @toddntucker & others for pushing that idea forward. My book adds to that.

Over the six years between headline-grabbing conferences in the climate calendar, the global economy consumed half a trillion tonnes of virgin materials.

This means that between the 'COP25 in Paris', 2015, where the Paris Agreement was formed and COP26 in Glasgow, 2021, 70% more virgin materials were extracted than what the Earth can safely replenish

HALF A TRILLION TONNES OF VIRGIN MATERIALS, OUR WORLD IS ONLY 8.6% CIRCULAR.

Turning the Desert into a Self Sufficient Eco Community Oasis
https://youtube.com/watch?v=voFbtbXRZ8I&feature=youtu.be


Last year I met a man who has spent 5 years living off grid in the Mexican desert turning degraded land into a fertile, self sufficient homestead.

His aim is to demonstrate that the droughts, water shortages and increasing desertification around can be reversed by integrating a combination of simple water retention methods like digging lakes, ditches, swales, ally cropping and rotating small herds of cattle and goats.

Using local materials from the site he has created several eco buildings using including 3 adobe earth domes a cob houses, rammed earth and straw bales buildings.

Members of the government for agriculture, housing and indigenous people now visit the ranch to learn from his experiments.

OUKE: tusil jsem, ze ti nejde jen o kyslik. jak jsem zminil, je to komplexnejsi a ted Tadeas musi omluvit ze nedodam linky, ale spousta tu uz probehlo a nemam cas dohledavat zpet

1. to ze nebude zivot v mori souvisi s jidlem pro velkou cast obyvatelstva (12%, u low income zemi jde az o 20% prijmu animal proteinu denne)
2. to vyusti v migraci a vyssi tlak na lokalni zdroje, vcetne vody, intenzifikaci vyroby (pravdepodobne vic plochy, pokud technologicky nevyresime jidlo jinak)

3. korali maj vliv na druhovou rozmanitost v mori, potravni retezec, pokud nebude pestrej, nebudou v hojnosti vyssi morsti zivocichove, kteri ukladaji co2 (resp. kyselinu uhlicitou) rozpustenou v mori do svych koster, ktere pak padaji ke dnu (podobne jako stromy odcerpavaji co2) (asi se da mitigovat mangroove porosty a potapenim / stavenim struktur v morich a oceanech)
4. pokud nebudou ani rasy, podobne jako rostliny na sousi, nedojde k odcerpavani co2 (a opet ubude skrysi pro nizsi morsky zivocichy)

5. pokud by nebyly stromy, dojde k velmi rychlemu odcerpavani vody z krajiny, nejen kvuli tomu, ze sami zadrzuji vodu, a pak ji nasledne v horkych dnech uvolniju ve forme vlhkosti, cimz ochlazuji/reguluji teplotu okoli, ale delaji stin pred sluncem/snizuji odpar v pude pod nimi, zadrzuji i vlkost pod korunama, i na zemi pod listim atd. pro dalsi zivocichy. Taky zabranuji vetru, aby vysusoval krajinu. Pomahaji i lokalni tvorbe mraku / lokalnim bourkam, takze je otazka, kolik by pak kde bylo srazek.
6. bez vody v krajine nebude krom prehrad moc mist, jak nas uzivit. Maximalne opet technologie odsolovani z more.

== opet boj o zdroje, vysoka migrace, mozna i valky, rozhodne snizeni zivotni urovne pro vetsinu obyvatelstva na zemi

7. zvysujici se teplota bude mit za nasledek rozpinani vzduchu, ktery bude ridsi, a to vcetne kysliku. co2 je tezsi (ma vyssi hustotu nez kyslik/zbytek vzduchu), bude se tak koncentrace hromadit vic pri zemi a umocni efekt. jake ma dopady zit ve vydychane mistnosti vime
8. zvysujici se teplota sama o sobe bude mit dopady na zdravi lidi - a to ne jen ve forme umrti, ale energie/aktivity/pracovni efektivity - jake je to pracovat v lete vime (tohle konkretne se da asi mitigovat klimatizaci)
9. zvysujici se teplota bude mit umocnujici efekt na odpar vody z krajiny, na produkci rostlin, ktere nas/nami chovane zvirata zivi, stejne tak na produkci zivocisne vyroby (napr. mleka)

bude toho vic souviset dohromady, to jen tak naokraj, ze ten kontext kysliku je jen mala soucast celyho obrazku

TUHO: Strasne bych si pral aby nebyl, ale vsechny indicie rikaji ze je. Kromne lidi ktery s tim maji nebo meli neco spolecneho a tvrdi ze to umi sestrojit, ale neumi vyrobit.

The human physiological impact of global deoxygenation | The Journal of Physiological Sciences | Full Text
https://jps.biomedcentral.com/articles/10.1007/s12576-016-0501-0

There has been a clear decline in the volume of oxygen in Earth’s atmosphere over the past 20 years. Although the magnitude of this decrease appears small compared to the amount of oxygen in the atmosphere, it is difficult to predict how this process may evolve, due to the brevity of the collected records. A recently proposed model predicts a non-linear decay, which would result in an increasingly rapid fall-off in atmospheric oxygen concentration, with potentially devastating consequences for human health. We discuss the impact that global deoxygenation, over hundreds of generations, might have on human physiology. Exploring the changes between different native high-altitude populations provides a paradigm of how humans might tolerate worsening hypoxia over time. Using this model of atmospheric change, we predict that humans may continue to survive in an unprotected atmosphere for ~3600 years. Accordingly, without dramatic changes to the way in which we interact with our planet, humans may lose their dominance on Earth during the next few millennia


...

It has been estimated that ~70% of atmospheric oxygen is produced in the oceans by photosynthesis in phytoplankton [12]. There is concern that uncontrolled global warming could lead to a catastrophic loss of this vital source of atmospheric oxygen through inhibition of photosynthesis [13].

...

The atmosphere and sea act as the main reservoirs for oxygen and major events such as natural fires can alter the balance to a minor degree. Therefore, in simple terms, if the number of plants decreases, the oxygen-generating capacity of the Earth is reduced; and if the number of animals (including humans) increases, then oxygen consumption will rise. Combustion of fossil fuels has a major impact on oxygen and carbon dioxide levels in the atmosphere, there being a correlation between fossil fuel-related global warming and depletion of oxygen from the oceans [11]. Furthermore, oxygen is consumed not only when fossil fuels are used in combustion, so the relation between decline of oxygen and rise in carbon dioxide is not linear. For example, oxygen is consumed in many oxidation processes in industry for materials manufacturing, where there is no direct combustion of fossil fuels. One of the uncertain factors in the model of oxygen decline lies in the rise of new technologies, which may appear “green” in terms of carbon dioxide emissions but at the same time would deplete oxygen—these need to be monitored in the context of the atmospheric oxygen decline.
