LINKOS: ad dojeni - ano, vyborny vysledky :) bez legrace, pokud se na to divam tou produkcni optikou, tzn. produkce krmiva, konverze krmiva na vyslednou kmoditu, genetika. ... tohle hledisko nema za cil integrovat perspektivu ekosystemu, takze mu to nevycitam. :)


pokud se na to kouknu z hlediska toho, jak treba operujou nektery regenerativni chovy - je tam vic hledisek, a to dulezity hledisko, zastresujici, je management ekosystemu :) - co to v ekosystemu ve velkem dela. v praxi: typicky ten land use je nebo muze byt nejakej smisenej - pasenej [a dojenej] sad, kombinace s tim, ze zaroven jsou tam kurata nebo slepice nebo kruty atp. [prochazej v cyklech], misto stabilnich budov se pouziva nejaka mobilni dojirna [jsou to maly chovy, nevim jaky jsou nejvetsi, co tohle delaj]. aspekt co se resi je ta nespecificnost ucelu, tzn driv byla krava tazny zvire, zvire na maso i zivre na mleko, proto tolik nedojila, protoze nebyla slechtena jen na tuto jednu funkci, protoze nikdo nechtel, aby zastavala jen tuto jednu funkci. cili pak v ramci techle regenerativnich pristupu mas stado se smisenym uzitkem, tj. maso-mlecny, tzn. krava odchova svoje tele a to pak zabijis na maso [u kravy slechtene ciste na produkci mleka je to nesmysl a bycky zabijis, protoze nemaji konstituci takovou, aby meli smysluplnou produkci cehokoliv]. v tomhle pristupu to vypada v praxi napr. takto, tzn. produkce 8 l, zatimco zivi tele, ktere je zase paralelni zdroj potravy / vystup z toho ekosystemu.

Study predicts the oceans will start emitting ozone-depleting CFCs

By the time you get to the first half of the 22nd century, you'll have enough of a flux coming out of the ocean that it might look like someone is cheating on the Montreal Protocol, but instead, it could just be what's coming out of the ocean," says study co-author Susan Solomon, the Lee and Geraldine Martin Professor of Environmental Studies in MIT's Department of Earth, Atmospheric and Planetary Sciences. "It's an interesting prediction and hopefully will help future researchers avoid getting confused about what's going on."

tak na ty produkci ty taxiformis rasy pracujou dva startupy, symbrosia na hawaii a volta ve svedsku, ty to maj asi rozjetejsi



A startup out of KTH Royal Institute of Technology; Volta Greentech and Symbrosia from Yale University, are both working to grow A. taxiformis. Symbrosia is looking to integrate the cultivation with whiteleg shrimp on land, using a patent-pending technology

Volta Greentech is developing a scalable, sustainable, and automated land-based seaweed cultivation system - tailored for the selected species of seaweed that are crucial ingredients in Volta Seafeed. A land-based factory enables optimization of temperature, light, and nutrients to maximize the seaweed's growth rate while ensuring a high and standardized quality of the feed supplement.

To meet the increasing global demand for the solution, we are rethinking how to produce seaweed at scale. Volta Seafeed has an immense impact potential, but as no one has been growing this type of seaweed at scale before, the global demand far exceeds the supply. Looking at existing production methods for seaweed, we quickly realized that we needed to take a different approach to reach the scale we are aiming for. Therefore, we went to the drawing board and looked at what would be necessary to produce Asparagopsis at scale for global implementation.

The seaweed is grown in vertical bioreactors with sensors and automation in a controlled environment to maximize seaweed growth and quality to lower production costs

Seawater is used as cultivation media and is naturally rich in nutrients. The seawater is recirculated in the system, and extra nutrients and CO2 are added to boost seaweed growth.

The LED lights and the rest of the facility are powered by 100% renewable electricity. Waste heat from nearby industries is used to heat up the seawater and facility to the right cultivation temperature.
