Do we really appreciate soil as we should? That skin on the surface of the earth, which takes so long to grow, is extremely fragile, and yet without it there would be no living things.

Everything we wear, live in, drink, read and use, ultimately comes from soil. It hosts our food supply, filters water for clean rivers, creates amazing landscape and should be revered as the most complex ecosystem on the earth.  

It is also the warehouse of excess carbon, kept full by plants that take carbon dioxide out of the atmosphere through photosynthesis, and produce carbon, essential to plant growth. When plants and other dead organic matter enter the soil, it becomes food for microbes that produce enzymes which convert the soil carbon back into carbon dioxide that goes back into the atmosphere. Fungi and bacteria, both decomposers ensure the right consistency of biomass, which together with minerals are the building blocks of soil.

This is how it should be!

But ignorance and greed have played havoc with huge areas of land, rendering the soil into nothing more than lifeless dirt. Once we have eradicated the living soul of soil, it is a long process to restore it. It took millions of years to make, but with good management and the right boost, it is amazing how it will regenerate itself.

Chemical fertilizer is salt-based, and kills the living organisms, which results in more and more industrialised nutrients required. Good for some pockets, but a killer to any ecosystem because the balance between living organisms has been compromised, demolishing eco systems. A system that is addicted to fertilisers, cannot be sustainable. It is sick, gets more symptoms and becomes susceptible and easy prey to pests.

This not only effects the plants, but has a direct effect on our health. Plants grown in dead soil, lack the minerals, vitamins, proteins and the multitude of other nutrients our bodies need. But no problem for Mr big pocket, he will sell us all of this in a capsule!

Destroyed soil does not host natural forests, so essential for the water cycle. Coastal forest absorb mist blown in from the sea, and feed the soil, as well as through transpiration feed the onshore wind with more water. Which is then fed to the next forest further inland, and then onto another. Through this process water is passed on to inland forest across the world. Destroy coastal soils, and the knock-on effect will cause desertification thousands of kilometres inland. Desert don’t produce much food!

Technology has allowed for positive scientific information to be shared with such a broad sector of society, allowing so many more people to realise that soil is an integral part of us. There is a new exciting awakening to the importance of preserving it in its natural form, and reversing the damage that has been done.

As Biosphere Reserves, with all our partners have been doing all we can to encourage this “soil” revitalisation awareness. Please come and join us.

Breeding microbes

Nutrient rich soil with a flourishing ecosystem

The Biosphere Greenhouse and Food Garden host a multitude of practices in growing vegetables, herbs, and flowers as well as compost production. It is a hands-on educational environment for young and old alike. CWBR facilitates workshops at the Biosphere Hub, installs, and assist in existing vegetable gardens at visited locations. Taking into consideration the positive aspects and limitations of each individual space utilizing it to a fullest potential. The practice of growing one’s own food is learned through practical involvement from getting the soil ready, planting, and shared knowledge in caring for the garden.

The Biosphere Hub garden is looked after by visiting volunteers and is overseen by the Biosphere core team.

“We as volunteers are working in different areas in the garden. From planting seeds in the green house to replanting the seedling on the patches around the garden. During the summer month, the garden comes to a point where we can start harvesting the vegetables.” #foodlovers

A brief summary of some practices in the CWBR Food Garden

The Greenhouse. The infrastructure and design of the greenhouse provides an ideal space to produce a vast amount of seedlings throughout the year with a semi-controlled environment. Currently, the space is also housing a jungle of vegetables and herbs that flourish due to the conditions. At the moment the CWBR greenhouse is bursting with spinach, cucumbers, melons, tomatoes, corn, and herbs. 

Wormery for fertilizer. Selected food waste, hay, horse dung, and lots of worms covered in cardboard in an enclosed environment (such as a wooden crate) creates an environment where worms can reproduce and break down the waste to fertile soil. Installing a tap in the worm box to collect a liquid from the worms brings great benefits to the garden. Organic produce. The bi-product, worm leachate or worm juice, is full of good microbes that increase growth in vegetables – especially pumpkins, is a natural insect repellent, and can stop root rot. The spray mixture is diluted 1 juice/10 water.

The seedlings once large enough to be moved outside are planted in Huglekultur raised garden beds. These beds are long lasting compost heaps that regenerate themselves, created from twigs, branches, and reeds. They are ideal for areas with hot weather and do not require much irrigation. When planted, the seedlings are covered in hay and cardboard for mulch and to retain moisture as well as be protected from the strong sun.

Companion planting, a practice as old as time used by people worldwide. Companion planting has benefits such as growing healthier plants with higher crop yields, making the most out of the space in your garden, pest control, and attracting pollinators.  The natural chemicals exuded from the root networks of the plants create a thriving environment. The opposite is also true, certain plants planted together will stunt each other’s growth, reduce crop yield, and make the growing plant more susceptible to diseases and insects.

Collecting seeds for the next harvest. Some vegetables and herbs are left behind to collect seeds or beans, for example, for the next season. When herbs and vegetable plants produce flowers, it is an indication that seed collection can be done soon from the flowers themselves. Vegetables are full of seeds that can be collected for planting.

Anything is possible. Whether in a small or big space, food gardens with the right care can flourish almost anywhere.

The CWBR Hub showcases examples of a keyhole garden, hanging garden, permaculture gardens, and always expanding with new methodologies and introduction systems to add to the cycle of food production encouraging self-sufficiency.

No limitations in imagination. The produce from the garden is shared with many and used for CWBR projects. Recipes shared, new recipes created, vegetables pickled, and herbs dried.

The Importance of pollinators

Pollinators are an essential part of seed production. Organic food gardens create a symbiotic relationship between plants and insects.

with Bonnie People Project, MAKE, and Care Career Connection

Arranged by Luxembourg volunteers, the purpose was to have a kids’ fun activity day and to provide the opportunity for the facilitators from the organizations to get to know each other better.

The two groups from different areas arrived just after 9, ready for a packed programme. The kids got to know each other over breakfast and were excited about the day ahead.

They were split into groups for the hike up to a viewpoint overlooking the valley. The purpose of splitting into smaller groups was to encourage the children from the different areas to interact with each other.

Once back, the children rotated between activities which included karate, dance, art and crafts and food gardening. Members of Care Career Connections arrived just in time for lunch and had time to join in some of the activities.

For lunch the volunteers prepared hamburgers, salads, and for dessert, a delicious ice-cream!

To mark the event with a memorable item to take home, the children left with tote bags on which they had made personalized prints and an apple for the road.

It was a very successful day with laughter, play, learning new things, and getting to know new people. Two boards, with the Bonnie and CWBR logo were also signed by all who attended the day.

Biosphere team and volunteers

Our planet is in urgent need to develop sustainable methodologies and emission-reduction programs for food production, energy production, wastewater treatment... you name it! Often emission-reduction programs lack the ability to boost economic growth, which is the first priority for most of the developing countries. However, societies and communities are increasingly moving from conventional methods to produce and discharge goods to more into resource recovery -based models and waste-to-energy type of systems to avoid and reduce negative impacts of the changing climates. Cape Winelands Biosphere Reserve as an environmental organisation tackles both, climate change adaptation, and mitigation measures.

In my studies I mainly focus on water management and treatment, so once I heard about Cape Town’s water crisis I knew I would have to go see how the situation is and what I could do for helping the locals. One student from my University had done his research internship at Cape Winelands Biosphere Reserve the previous year, so I quickly emailed the organisation and got a positive response. Soon we skyped about the topic of my research and thought that I could work with a Swedish wastewater treatment technology, called Aquatron, and test it in South African conditions. The CEO had done some background research on the technology for years and this created a perfect opportunity to start to examine the system.

Soon after moving to South Africa I found out, that problems with the existing South Africa’s wastewater treatment system are diverse. The wastewater treatment plants are lacking capacity due to the growing population, as well as lack of financial support and maintenance. Another serious problem in South Africa is the vast amount of untreated wastewater that is discharged into the environment, especially wastewater effluent from townships and informal settlements. Many of the areas are not connected to the sewage system, which causes pollution and eutrophication in the majority of the rivers and other water reservoirs. Thus, the goal of the research was mainly to build an alternative sanitation system to the current water crisis in Western Cape to reduce pollution and overall water quality risks.

In addition to this, we also decided to expand the system with a greenhouse, aquaponics, and a vertical garden. First, the wastewater from a toilet, kitchen, and shower flows into the greenhouse, where Aquatron is placed. From there it continues first to aquaponics, and finally to the vertical garden. Furthermore, a constant flow vertical garden was built to offer a solution for local food production, especially in high density areas. Aquaponics in different sizes can be used for food production, but also as storage tanks for treated wastewater. With solar water pumps, the constant water flow system prevents eutrophication and other unwanted nutrient accumulation and bacterial growth.

The first order for 100 Aquatrons was made this year and a video of a panel discussion with various experts will be published soon! Aquatron program offers a solution to the current water crisis, and it will make a huge contribution to the CWBR and other community projects and generate regular income. Instead of relying on emission-reduction efforts, this alternative proposes a technology that locally treats wastewater and can increase economic and social development.

I want to thank CWBR for making it possible for me to visit South Africa, learn about the beautiful nature and cultures there and most importantly conduct a research that has a great potential to help to mitigate the drought. Here is a short video of my stay and the Aquatron project:

Aquatron briefly

Aquatron separates liquids from solids without any moving parts or chemicals. This is accepted worldwide as the most sustainable water toilet principle.

The toilet is connected to Aquatron, which separates the excrement and treats liquids with UV light. The water further continues to aquaponics where the water is organically post-treated, and plants use the nutrients as fertilizers to grow food and feed local citizens. The water is then pumped up to a vertical garden to maximise food production. After this the water flows back to the aquaponics. Once the circular system is fully functional, the system will be removed from the municipal grid, and the system works as closed, constant flow system.

To prove the system functionality, water quality analysis were made at Stellenbosch University WA lab, where Heterotrophic P/C per 1ml at 35°C, Total coliforms per 100ml, Faecal coliforms per 100ml, and E.coli per 100ml, as the general water quality indicators, were examined.

Once the separator and the UV unit were perfectly levelled, and the pipes’ inclinations were checked properly, this resulted in drinkable water quality. The wastewater treatment system was proved to work in South African conditions if properly installed and is a recommendable solution for the current toilet systems in informal settlements, mid- to high-income households, and companies.
