This is interesting from Imagine Zambia

“Imagine Zambia hopes to plant 20,000 trees for Ngabwe and 20,000 for Ministry of Education of Zambia (with 5 trees for every school at about 4,000 schools across Zambia.) We will plant a variety of trees including Moringa and fruit trees at locations across Zambia so that communities and students will learn about nutrition.

Moringa, which can be made into a powder, tea, or oil, provides significant quantities of potassium, calcium, protein, iron, vitamin A, and vitamin C. Moringa truly is the miracle plant: by using the dried seeds you can even purify drinking water overnight and kill 90-95% of bacteria in the water. Across Zambia, we can also use these trees to provide nutrition for orphans, vulnerable children, expectant and breastfeeding mothers, and other people in the community who need immune boosters and access to clean drinking water.

These nurseries will also provide local farmers with seedlings for their own needs and propagation of diverse species of trees, herbs, and vegetables. They will be able to process the seeds and leaves and seedlings and sell them all over Zambia. The nurseries will also restore vegetation in areas that have previously been cleared. This will increase overall production of food in the area, increasing food security. This will also exemplify good agricultural practices like composting and companion planting.”

This is a truly inspirational story, clipped from the BBC and written by Kieron Humphrey in Lusaka, Zambia

Elleman Mumba makes an unlikely celebrity. He is not a singer nor a footballer – he is a 54-year-old peasant farmer from southern Zambia. Yet he has appeared on the front page of a national newspaper and been interviewed for numerous radio and television programmes. “They said I was using juju in my field. I felt very bad, but I knew I wasn’t using witchcraft” said Elleman Mumba

Mr Mumba grows maize and groundnuts on his small plot of land in Shimabala, just south of Lusaka. Feeding his family used to be a problem. “The yield was very little. We were always looking for hand-outs; we had to rely on relief food.” Like many farmers, Mr Mumba had no oxen of his own to plough his field. He had to wait in line to hire some, which meant he often failed to plant as soon as the first rains fell – with disastrous consequences.

Researchers say that for each day’s delay, the potential yield shrinks by between 1% and 2%. Then, in 1997, Mr Mumba suddenly found himself in the vanguard of a quiet agricultural revolution. His wife had been given free training in a system called conservation farming, and persuaded him to try it. Conservation farming is about doing less to get more. Instead of ploughing entire fields, farmers till and plant in evenly spaced basins. Only a tenth of the land area is disturbed. This reduces erosion and run-off – where soil and nutrients are washed away by rain.

“That season I had 68 bags of maize – enough to feed my family and buy four cattle,” he says, blazing with pride at the recollection. Using just a wide-bladed traditional chaka hoe, Mr Mumba had dug a series of shallow rectangular planting basins in his field during the dry season. It was a tough job to break the sun-baked soil, but he persevered, and was ready to sow his seed with the first rains. The basins had punched through the layer of compacted earth created under the topsoil by repeated ploughing. Roots and rain no longer struggled to penetrate this “plough pan”.

The crop flourished in spite of low rainfall and some of Mr Mumba’s neighbours regarded his success with suspicion. “They said I was using juju in my field. I felt very bad, but I knew I wasn’t using witchcraft. I told them: ‘In CF there’s no juju. It’s just that you conserve water, so even when the rains are light, you are able to get something.'”

Now many of those who called him a witchdoctor have followed him into conservation farming. It is a growing trend.
Across the country there are more than 160,000 farmers using basins or other minimum tillage methods, including large-scale commercial farmers.

For big or small, the principles are the same:

* disturb the soil as little as possible
* use natural processes as well as fertiliser to replenish its nutrients
* leave crop residue in situ rather than burning it off
* rotate crops

Dissenters say there is not enough empirical evidence to support the promotion of conservation farming as a magic bullet for sub-Saharan Africa’s food shortfall. But several countries in the region are investigating its potential, hence the stream of visitors to Mr Mumba’s door. They want to see if an average farmer really can produce such good results with just his hands and a hoe.

Giggling at all the attention he is getting, Mr Mumba is pleased to say yes, he can.
