Invest in Zambia

The Zambian Economist has partnered with Brick World Zambia Ltd, an indigenous company based in Solwezi, as we try and build Zambia one brick at a time. The aim is to support our nation not just with words but also deeds. An investment flyer is set out below. For further information please email : cho@zambian-economist.comBrick World Zambia Limited


  1. I wonder if anyone has heard of sand dams, which are basically small walls across dry riverbeds and waterways, which collect debris, which then during the rainy season can hold upto 40% of it's volume in water.

    They stop erosion, and keep water on the land for longer periods. They can be used to dig shallow (low cost) wells, create tree lines, and even provide water for cattle.

  2. MrK,

    Yes, I think so, sounds like a small "check dam and percolation pool" (sometimes "percolation dam") which is an excellent device for recharging groundwater in areas with seasonal rainfall. These have been employed with great success in rural India by local organizations. Some good info available here:

  3. No commenting option at the Brickworld post. I'm sure Yakima could give his opinion on this topic too.

    Biochar (complety burnt, near 100% carbon) can be used for land reclamation, while providing heat that can be used for all kinds of purposes (heating, electricity generation, etc.).

    Biochar is a substance that is extremely porous, and a host for micro-life in the soil, and attracts water. Biochar was (it is presumed) first used by the Amazon Indians, to create Terra Preta, which is a manmade soil that is extremely fertile.

    Funding could come from: eco projects, carbon sequestration (like carbon credits sold at for instance the Chicago Climate Exchange).

    On the Adam-etort Kiln

    (Notice the Adam Retort Kiln is made from brick.)

    On Tera Preta and Biochar:

    Biochar - agrichar - Terra Preta

    So here you have a possibility that would have a lot of side ways for generating income. You could build (and sell) Adam-Retort kilns, use the biochar/agrichar to reclaim land (buy poor land cheap, improve it and sell it at a higher price as agricultural land), sequester carbon for carbon credits (well over $5 to $7 per tonne of carbon sequestered - remember that biochar also attracts soil life and aids in soil formation so there would be a carbon sequestration multiplier effect - you sequester much more carbon than just the biochar put on or in the ground).

  4. Thanks for reposting this comment here.

  5. Some years ago, someone posted on this blog that they couldn't farm on land because it was largely clay. Here is a video by Michael Melendrez in New Mexico, on how clay can be reformed into fertile soil using humus:

  7. Anon,

    Drop me an email and we'll take it from there

  8. I hope this it will help you
    In the book you will read about the challenges of designing low-emissions biochar production systems from small-scale stoves to farm-scale pyrolyzers. Another section of the book is devoted to explaining simple tests to characterize biochar and methods for conducting valid field trials.

  9. I really like the concept of biochar. It can be incorporated into compost, and can really speed up soil formation.
