> Did you know that the Aztecs created floating gardens called chinampas because they lived on an island in the middle of a lake? The Aztec capital city, Tenochtitlan, had a large population, so to help feed the people in it, the Aztecs used these island gardens to cultivate crops. This form of gardening was important for helping to sustain the Aztec Empire. The Aztecs built canals between the chinampas to navigate between them.

Food sovereignty is a matter of life and death in Gaza, where Israel has been deliberately destroying Palestinians’ ability to sustain themselves.

For Yousef Abu Rabee, from Beit Lahiya in northern Gaza, farming ran in his blood. He had been doing it from a very young age, the 24-year-old said with pride when interviewed by The Electronic Intifada in September.

But over the past year, many farmers in Gaza like Abu Rabee have had to abandon their land, crops and way of life due to Israeli bombing and evacuation orders. Instead of producing their own food, they, like everyone else in Gaza, have become dependent on the little humanitarian aid allowed in as Israel deliberately destroys Palestinians’ self-sufficiency.

I stumbled on this brief article while looking through this solarpunk blog. On the farm I worked at growing up, all but one of our greenhouses were plastic stretched over a metal frame. We replaced the plastic fairly often (I'm not sure how often - I know I helped do it more than once, but probably not for the same greenhouse) due to sun and wind damage. The old plastic was pretty useless at that point unless you needed a dropcloth with some cracks in it, so it usually went in the dumpster and then to our local landfill.

It sounds like these folks soaked some sort of fabric in beeswax, and I'm curious how well that holds up. Certainly it'll need replacing at some point, but so did the plastic, and at least the textile and wax can be composted eventually. Does anyone have any experience with this?

Researchers around the country are exploring agrivoltaics, or co-locating solar generation with agriculture in a mutually beneficial way. Projects range from growing tomatoes in California to wild blueberries in Maine, with varying levels of success.

Acciona regional manager Kyle Charpie said that sheep grazing appears an especially promising form of agrivoltaics, and one that the company is likely to continue exploring globally. Solar operators need to keep vegetation controlled, and sheep are a more effective and ecological way to do it than mechanized mowing. Acciona has long had a sheep agrivoltaic operation in Portugal, Charpie noted, and two projects in Texas are underway.

A Deep Winter Greenhouse (DWG) is a greenhouse designed to limit the amount of fossil fuel it takes to grow crops during cold winters. DWGs are passive-solar greenhouses that rely on energy from the sun to heat the building instead of more traditional heating sources.

There are a few important aspects of the design that make this possible. DWGs are built in an east-west position, with a glazing wall that faces south. This wall can be specially angled, depending on latitude, to get the most possible solar energy on the coldest day of the year. The sun heats the air inside which is blown underground with a fan and stored in a thermal mass made of rock or soil. This heated thermal mass acts as a heat battery and stores heat for when it is needed at night.

DWGs in can be used to grow crops that thrive with minimal light, providing year-round production capacity for small-scale farmers and gardeners. Crops well-suited to DWG production include a variety of lettuces, herbs, brassicas, Asian greens and sprouts.

Additional resources on building underground greenhouses can be found here (especially at the bottom of the article!)

This article really highlights to me how critical infrastructure is to achieving a sustainable food system. There are plenty of people growing food in an ecologically mindful manner, but they're so atomized that they need to do everything themselves. And the infrastructure is so centralized that you're forced into the industrial model if you want to go beyond the farmer market level. We need more meat lockers, local grain mills, oil pressers, etc. to build out regional food production networks.

Hi there, my chicken has a swelling on her cheek and it's causing her some distress can anyone please advise me?

I saw the need for a community dedicated to hydroponics, and there hasn't been one on the fediverse from what I've seen. So, I just created one 🤷

In my opinion, it fits perfectly to Solarpunk. Why?

• It's very ecologically sustainable. Compared to soil, it barely needs water and fertilizer
• It's as simple, or high-tech as you want. There's everything between just a simple reused wine bottle on your window top with the Kratky technique and a high tech aeroponic tower with smart home integration and grow lights.
• It's great for the plants and the people. In hydroponics, you get way less pests and therefore need barely any pesticides, and plants grow faster. You can grow them on your balcony or very small spaces like I do and can even enable city farming with that, making locally sourced fresh veggies very simple.
• It's perfect for people who don't have a green thumb. It's a completely different approach to growing plants.
• It's a lot of fun
• And much more

There are many different types of hydroponics, like:

• "Classic" hydroponics, like deep water culture, nutrient film technique, etc.
• Semi-hydroponics with hydroton or other inert media
• Aeroponics, which sprays the nutrient solution on the roots, which are growing into the air
• Aquaponics, where the plants grow basically on fish poop
• And many more

Every technique is welcome!

For those of you who are doing hydroponics, what do you think of this system? Is it a good system for a beginner on a budget? Or is there a better system?

Did you know that simply digging a slight ditch can completely change the health of a landscape?

In modern landscaping, any sort of hole or ditch is considered a “dangerous tripping hazard,” “unsightly,” or “a waste of space,” so everything is smoothed out. If you go to most cities and farms, the only non-flat places are designed to carry water away from cities, rather than hold onto it.

This thought process can not only increase overland flooding and wash away topsoil, but it also gives water no place to sit and be absorbed into the soil. Without any water capture gradually trickling into the soil and creating an underground reservoir, the landscape becomes less drought resistant and more susceptible to wildfires.

The permaculture techniques to correct this have many names and methods, including:

• Demi-lunes / Half - moons / Semi-circular bunds
• Eyebrow terraces / banquettes
• Negarim
• Contour bunds
• Micro basins
• Planting pits / Zai pits / Chololo pits
• Swales

They might be different shapes and use slightly different methods, but they all do all work the same on a basic level. The idea is to dig or build a shape that will slowdown and/or catch some of the movement of water. This can make the soil more absorbent (dry and hardened soil does not absorb water as easily) which promotes healthy microbiome of the soil.

Even if the water dries out visibly during the dry season, underground, they could be making a huge difference.

!

It is not new science, but instead something many cultures around the world have a long history with, but many modern farming practices(mostly to make it farming machine friendly) and development flatten everything out. If people changed this point of view, it could change our landscapes.

In cities, they look like a slight ditch in front of a house, or a creek in a greenspace.

! !

(Image Sources: Image 1 | Image 2)

For other landscapes, it could be just slight indents in un-farmable areas, or ditches dug around farm perimeters.

They do not have to be very deep, and often do not need any fancy equipment to dig(most just take a shovel), but they can do amazing things.

In the process of reversing landscape desertification, it is proving drastically helpful. As the underground water reserves build, so does the vegetation.

Vergenoegd Winery(South Africa) is handling pests using a unique solution; ducks. These ducks enable the winery to be pesticide-free.

Video: https://youtu.be/H6Ehoxu9QY8

The reason for this is that ducks love to eat all sorts of garden pests: including slugs, snails, mosquitoes, ants, and more.

> "You may also be wondering: Why ducks and not chickens? While it’s true that chickens can help to keep bugs at a low in your garden, they also have a habit of being a little less delicate around garden plants than ducks do. Chickens love fresh greenery and will be more than happy to eat your homegrown lettuce, whereas ducks will focus less on your hard work and more on the bugs in your yard." | The Spruce

Similarly to the winery, ducks are also often employed to help with rice paddies. The ducks not only help with pests and fertilization, but their paddling helps both aerate the water and kick up mud(the increased oxygen and decreased light can cut down on algae or weed growth).

As an added benefit, the eggs and/or meat can be eaten. I know that will upset many of you but the added financial benefit of that is further incentivizing farmers to switch from herbicides and pesticides, to ducks.

> "Another study done by Practical Action2 concluded that the duck-rice farming technology led to several socio-economic and environmental benefits. The ducks were introduced into the rice fields 10-20 days after rice was planted until the flowering stages. The study also found out that this form of farming was better in rice production than others as it led to decreased production costs, high yields achievement, had benefits for the environment and led to increased income. Further, it’s stated that 20% higher yields can be achieved with the use of this system, 50% increase in income can be achieved as well as enhanced food security through the consumption of duck meat." | Permaculture Research Institute

For food forests, you do what you can to use edible plant life to mimic the ecosystems of a wild forest.

>“A food forest, also called a forest garden, is a diverse planting of edible plants that attempts to mimic the ecosystems and patterns found in nature.” | Project Food Forest

If done right, this system will…

• Promote a healthy soil microbiome
• Increase carbon-capture (no-till)
• Prevent erosion
• Retain water

And more.

Personally, I suggest using as many perennials to your area as you can so you don't have to replant everything every year.

Here are some perennial examples that are for my specific area:

(⚠ means you may want to container garden them to prevent spread)

• 🥬Lovage (celery alternative)
• 🥗 Bloody Dock (chard alternative)
• 🥗 Good King Henry (spinach alternative)
• 🥔 Jerusalem Artichoke (root vegetable)
• 🥗 Sea Kale
• 🧅 Chives ⚠
• 🥝Hardi-Kiwi
• 🍓Wild strawberries
• Raspberries ⚠
• Wild blueberries
• Red or Black Currants
• Haskap/Honeyberries
• 🍇Valiant or Bluebell Grapes
• Rhubarb
• Saskatoons
• Pembina Plums
• 🍒Evans (sour) cherries
• Manchurian Apricots
• 🍎 Hardi-Mac Apples

If you want an easy way to help your local pollinators, then consider building a water station! Many plants and crops rely on pollinators, so the more you attract and help, the healthier your garden will be (for example: "“Bee pollination improves crop quality, shelf life and commercial value.”)

For a basic one, you will need:

• Tray or dish
• Rocks
• Water

The tray or dish is to hold everything, and the rocks are to give the pollinators something safe to land on. Without the rocks, you will likely end up with drowned bees. Due to evaporation, you may have to fill the dish once or more a day.

HOWEVER, although that is the most common method, there is another one that I prefer that was taught to me by local beekeepers. They use a refilling dog bowl instead of a dish, so it doesn't have to be filled as often.

!

While this was advice from beekeepers, the watering stations are not limited to honeybees; you may see all sorts of native pollinators visiting.

If you can't buy a refilling bowl, here is a tutorial on how to DIY one.

No matter what you choose, though, the pollinators will appreciate it! I do suggest putting the water in shade to limit possible algae growth.

>"The rock powder, usually basalt, is often scavenged from local mines or quarries, where it exists as a waste by-product. ERW companies collect the rock powder, sometimes milling it further to reduce the grain size. Then they truck it to farms, where it is used in place of ag lime.

Have you heard of The Great Dust Bowl? It was a series of dust storms in the USA that were so intense, they killed crops, livestock, and people during the the great depression.

The situation was amplified by a drought, but the dust was also human caused.

>“Following years of overcultivation and generally poor land management in the 1920s, the region—which receives an average rainfall of less than 20 inches (500 mm) in a typical year—suffered a severe drought in the early 1930s that lasted several years. The region’s exposed topsoil, robbed of the anchoring water-retaining roots of its native grasses, was carried off by heavy spring winds. ” Britannica

This dust storm was so thick that it blocked the sun.

>“Dear Mr. Roosevelt, Darkness came when it hit us. Picture taken from water tower one hundred feet high. Yours Truly, Chas. P. Williams." An unknown author writes to Roosevelt

Under the hands of desperate farmers, grasslands turned to landscapes so lifeless and dangerous, that many people abandoned their dreams and left.

One of the practices that amplified this disaster (that is a current farming practice to this day) is rototilling. During this, you flip the soil over, which can make planting easier. This comes with many problems, including:

• Destroying the soil microbiome. Healthy soil means healthy crops.
• More weeds. As you flip your soil you are allowing dormant seeds a chance to thrive
• Soil Compaction: As the soil gets more compact, it becomes harder for roots to work through it.
• Washing or blowing away top soil. Top soil is where the heathiest soil is, and it can be washed away if left uncovered
• Drying the soil. By leaving the soil exposed you are letting the sun bake out any moisture

Fixes:

• Crop rotation. This is a pre-medieval technique where you rotate what crops you grow in what soil. This can add nutrients to the soil, avoid nutrient depletion, reduce diseases, and reduce pests.
• Cover Crops. Never leave your soil bare. Cover crops can save your soil.
• Water Catchments. These slow down the movement of water, encouraging the soil absorbing it. Examples: bunds or swales.
• Alternative farming. Such as aquaponics or hydroponics.
• Food forests. Instead of rows of monoculture, food forest combine several different types of plants in a way that mimics a forest.
• Reducing food waste. To take pressure off food production. In Canada alone, $31 billion dollars worth of food waste is thrown out a year.
• Mulch. Putting mulch down can protect your soil while also keeping down weeds.
• Planting trees and bushes. Even if it is just on the outside perimeter of your crops, trees and bushes can help hold soil in place, reduce wind, and improve the general health of the area.

Did you know that you can grow your own bath sponges?

>"Luffa is a genus of tropical and subtropical vines in the pumpkin, squash and gourd family.” Wikipedia

Luffa plants are from southeast Asia, and can be grown in places with a long warm summer. The fruit can take a long time to grow and toughen it’s inner fibers (about 150-200 days), but after that time, they are ready to become sponges.

Explaining it simply, you peel the skin, wash the insides, hang them to dry, then you are done.

> “Getting all the seeds out can be a challenge, but the drier the sponges are, the easier the seeds will fall out. Save the best ones for next year. You can also cut open the sponges in any shape you want to remove seeds or make a loofah fiber mat.” luffa.info

When done, you can use the sponges for bathing, washing dishes, and even as industrial filters.

>"Findings in both studies showed that the more silverleaf nightshade was mowed, the more it developed ways to avoid destruction, Kariyat said. The taproot went down further, nearly 5 feet deep, in the first generation of mowed plants. More spikes popped out on the stem as a defense against caterpillars feeding on the flowers. The flowers became more toxic to caterpillars, leading to less pressure from natural predators."

Rocksolar’s Solar Water Pump is an efficient and environmentally friendly solution for water management in remote or off-grid locations. It harnesses solar power to operate, eliminating the need for electrical grid connections or fuel-based generators. This system is particularly beneficial for agricultural irrigation, livestock watering, and rural water supply.

For 31 straight days last summer, temperatures in Phoenix hit or topped 110 degrees, the longest such streak ever. That searing Arizona heat dehydrates crops and evaporates water the state needs to conserve.

Creating shade is one way to combat the problem.

By using solar panels, farmers can simultaneously protect their plants, save water and lower their energy bills – and some are doing just that with help from federal programs designed to encourage this sustainable method of growing.

Photovoltaic panels are placed above the crops, harnessing the sun’s energy while providing valuable shade.
