Growing Bamboo in arid regions:

In arid regions like Namibia, growing bamboo can be a rewarding and sustainable option, especially if water resources are limited. While most bamboo species prefer humid and tropical climates, some varieties are more drought-tolerant and can thrive in arid conditions. Here are a few bamboo species suitable for growing in Namibia and methods to conserve water while cultivating them:

1. Bambusa balcooa (Balcooa Bamboo): Balcooa bamboo is one of the most drought-resistant bamboo species and can adapt well to arid environments. It has thick-walled culms (stems) and can grow up to 20 meters (65 feet) tall. It’s often used for construction, handicrafts, and furniture.

2. Bambusa vulgaris (Common Bamboo): While Common Bamboo is more commonly found in tropical regions, it can also tolerate dry conditions to some extent. It grows relatively fast and reaches heights of around 15 meters (50 feet). This species is utilized for various purposes, including construction, fencing, and crafts.

3. Dendrocalamus asper (Giant Bamboo): Giant Bamboo is a tall and sturdy species that can handle dry conditions. It can reach heights of up to 30 meters (100 feet) and is valued for construction, furniture making, and as a raw material for paper production.

4. Bambusa textilis (Weaver’s Bamboo): Weaver’s Bamboo is well-suited for arid climates and grows up to 12 meters (40 feet) tall. As the name suggests, it’s commonly used for weaving and crafting purposes.

Water-Saving Methods for Growing Bamboo in Arid Namibia:

1. Soil Preparation: Prioritize soil preparation to ensure water retention. Add generous amounts of organic matter like compost or well-rotted manure to the soil. This enhances the soil’s ability to retain water and provides essential nutrients for the bamboo.

2. Mulching: Mulch around the base of the bamboo plants with organic materials like straw, leaves, or wood chips. Mulch helps conserve soil moisture, reduces weed growth, and provides a more stable soil temperature.

3. Drip Irrigation: Use drip irrigation systems to water the bamboo directly at the root zone. Drip irrigation is more water-efficient compared to traditional watering methods and minimizes water wastage through evaporation.

4. Rainwater Harvesting: Collect and store rainwater during the rainy season to use for irrigating the bamboo during drier periods. This ensures a sustainable water supply and reduces the dependence on other water sources.

5. Watering Schedule: Establish a regular watering schedule based on the bamboo’s water needs. Water deeply but less frequently to encourage the development of deep root systems that can access moisture from deeper soil layers.

6. Shade Provision: While bamboo requires sunlight to grow, providing some shade during the hottest part of the day can help reduce water evaporation from the soil.

7. Companion Planting: Consider interplanting bamboo with drought-resistant companion plants that can help shade the soil and reduce water loss. Suitable companion plants may include drought-tolerant grasses or ground covers.

By selecting appropriate bamboo species and implementing water-saving techniques, you can successfully grow bamboo in arid Namibia and enjoy its many benefits while conserving water and maintaining a sustainable farming practice.

Other benefits and uses:

One of my favorite applications of bamboo I recently learned about is de-acidifying soil after removing Eucalyptus. This ecological transition has many opportunities to create valuable products, sequester carbon in the soil (where we need it most) and pave the way toward restoring biodiversity.

Growing Bamboo in Aquaponics

Growing bamboo in aquaponics setups can be an innovative way to utilize water efficiently while fostering a sustainable ecosystem. Aquaponics combines aquaculture (fish farming) and hydroponics (soilless plant cultivation) in a symbiotic relationship. Here’s how you can grow bamboo in an aquaponics system with minimal water usage:

  1. System Setup:
    • Construct an aquaponics system that includes a fish tank, a grow bed for bamboo, and a water circulation system.
    • Fish waste provides nutrients for the bamboo, while bamboo helps filter and purify the water for the fish.
  2. Fish Selection:
    • Choose fish species that produce nutrient-rich waste, such as tilapia or catfish. Their waste will serve as a natural fertilizer for the bamboo plants.
  3. Water Filtration:
    • Fish waste produces ammonia, which can be toxic to fish. Beneficial bacteria convert ammonia into nitrites and then into nitrates, which are plant-friendly nutrients.
    • Water is pumped from the fish tank into the grow bed, where it circulates through the plant roots, absorbing nutrients and filtering out impurities.
  4. Bamboo Planting:
    • Select a bamboo variety suitable for container or hydroponic cultivation. Clumping bamboo varieties are often better suited for contained growth.
    • Plant bamboo seedlings or rhizomes in the grow bed, ensuring they have proper support to prevent falling over as they grow.
  5. Nutrient Uptake:
    • Bamboo absorbs nutrients and filters water as it circulates through the aquaponics system. This helps maintain water quality for the fish.
  6. Maintenance:
    • Regularly monitor water parameters (pH, ammonia, nitrite, nitrate) to ensure a balanced environment for both fish and plants.
    • Trim and manage bamboo growth to prevent overcrowding and ensure healthy growth.
  7. Harvesting Bamboo:
    • Bamboo can be harvested as needed for various uses, such as construction, crafts, or culinary purposes.

Projects Demonstrating Successful Bamboo Growth in Aquaponics:

  1. Bamboo Aquaponics in the Philippines:
    • In the Philippines, bamboo has been successfully grown in aquaponics systems. This approach offers sustainable bamboo production while conserving water resources.
  2. Urban Aquaponics with Bamboo in India:
    • Some urban farming initiatives in India have integrated bamboo cultivation into aquaponics systems to provide a renewable source of bamboo and maximize water efficiency.
  3. Educational Institutes and Research Centers:
    • Various educational institutions and research centers around the world have experimented with growing bamboo in aquaponics setups to explore its potential for sustainable agriculture and resource conservation.

Remember that successful aquaponics requires careful monitoring and adjustments to maintain the balance between fish, plants, and water quality. Additionally, consider local climate conditions and bamboo species when designing your aquaponics system.

Building Bamboo skills for Africa

Here’s an interesting take on Bamboo and it’s role in Africa, from a colleague in Uganda. This is what he writes:

“Like your community we need skillsets for correction and transformation of bamboo. Bamboo cutting is not given to all as well. Locally most use is for poles to support decking of storey buildings, to trap water in soils, shade some farms from aggressive winds/sunlight as well as poles for climbing plants like yams. For a plant that has several hundreds of uses, it could well help in areas like curbing charcoal dependencies as it can be used to produce briquettes for warming homes or for cooking hence act as a source of energy. We know it can be used in making bikes, biodegradable clothes, furniture.,toys etc. Also Asia is still blessed with skilled bamboo engineers and part of the future should be taking from where things are abundant to where they are scarce.

Besides I was able to design the shelves/counter at the Earth Complex Guesthouse from bamboo.

I wrote a project on bamboo greenhouses after consultations with an Indian Master Bamboo Greenhouse creator and Innovator and financing institutions are lagging behind in making necessary links between bamboo, all year round food production, sustainability, poverty reduction, profits, creating jobs and the fight against food insecurity..Below is my podcast on bamboo as an entry point for impact investing in Africa:; With necessary support an eco-friendly bamboo dragon can be unleashed.

I think bamboo, saw dust, old tires, elephant grass offer some great opportunities for fibre development while a study on needs or needs based approach will open doors on the types machines to design. Some homes or communities might for instance integrate mini vertical wind turbines while others could work with motor rotors or photovoltaic depending on the needs of each entity. Others might be a combination of many others including biofuels.

Below is a link to our interest in working with stakeholders to transform bamboo. It is the fastest growing grass and can help reduce dependence on depleted traditional forest wood species globally and in Africa just like it has several tested uses across the globe. https://youtu.be/p4UzKXS_fwE:
