The delicate balance of our ecological systems

When I was in school, we were taught that the cause of malnutrition in our communities was the lack of sufficient protein in the diet. Today, I am much older, and have observed that there is a malnutrition epidemic in the Lake Victoria region in Kenya where fish, a rich source of protein, is supposed to be a staple. At first, I thought this was a uniquely Kenyan problem. Then I saw Hubert Sauper's documentary, Darwin's Nightmare. Apparently, a similar problem exists in the Lake Victoria region of Tanzania.

The film demonstrates how commercial fish harvesting over the years has exhausted the fishing stock in Lake Victoria, creating an ecological crisis. The Nile Perch fillets harvested from the Lake are processed then transported by commercial aircraft to Europe. The same aircraft rarely arrive in Tanzania empty. In fact, they usually bear arms that are then off-loaded under the cover of darkness. So we have a situation whereby Europe is enjoying fish fillets from Lake Victoria while the locals feed on the remains of the processed fish: skeletons from which the fish fillets have been removed. In the meantime, other locals are killed by the buyers of the illicit firearms when violence erupts in the region.

After watching Sawyer's documentary, I looked into the history of the ecological crisis in the lake region. According to available information the Nile Perch are an alien species of fish, which was introduced into the lake in the 1960s, just before Kenya became independent. Over the years, this alien species had decimated local fish stocks by predating on indigenous fish species. Thus, an ecological imbalance has resulted in the lake.

The locals used to subsist on the lake's indigenous food species. However, these have been depleted by the Nile Perch. In the meantime, the most substantial protein source in their diet is the waste from the Nile Perch processing factory:  Nile Perch remains. Thus, they live on a diet deficient in the nutrients that they need. The people in the region have no means to secure separate sources of vitamin A and omega 3 fatty acids. They  do not thrive. Hence poverty, malnutrition and disease are common in the region. As if this is not enough, Lake Victoria is considered to be one of the large fresh water lakes whose future survival is threatened.

For long, residents of the Lake Victoria region have complained about the exhausted fish stock in the lake. There has been little if any response from the sitting governments. A few years ago, I remember reading newspaper reports that indicated that Monsanto was already in the region, and that the introduction of other genetically modified species in the region was a possibility. In some areas, the locals were uprooted from their ancestral land to facilitate these 'innovative projects'. Their only compensation was a promise of maize supplies to subsist on every harvest season.  Maize based diets are apparently at the root of chronic malnutrition in the region. So that news did not bode well for Lake Victoria region's people, whose nutritional status is already declining .

When I read reports of this kind about environmental degradation and the development of supposedly superior species for human consumption anywhere in the world, I often wonder how local leadership fits into the picture. How do governments decide that the efforts of scientists and multinational corporations are for the good of their people? Is there a rigorous effort to look into the pros and cons of the proposed projects? Does money change hands? Are the locals informed about the details of the deals? How about the rights of other nations? In the case of Lake Victoria, which is a resource shared by 3 countries, how do the decisions made by one nation impact the other 2? Most importantly, what is the long-term impact of foreign species and GMOs (genetically modified organisms) on the environment and on the people?

Concerned people need to start taking these questions more seriously and thinking about the legacy are we leaving our children.

Contemporary Africa's implication in its own underdevelopment

In early April of 2010, I was hosted at a Public Library for the presentation of my book, A Healthy You: Tame Africa's Child Malnutrition. I was quite surprised at the interest the contents generated: I had assumed the book would primarily interest Africans, but the audience was predominantly American. To cut a long story short,the presentation went well, and gave me fresh food for thought.

One issue that came to the fore during the question and answer session was the poor utilization of quality protein maize (QPM) in the place of ordinary maize to tame childhood malnutrition on the continent. Other developing continents seemed to have made greater use of this resource than Africa. One participant in the audience hinted that the African establishment seemed to enjoy "victimhood." The person speculated that they preferred to exploit the sympathy that poverty, disease, the orphan burden, and violence attracted than to do the hard work that was necessary to undo institutional dependency on foreign aid.

Globally, research on QPM has been ongoing for many years. On the African continent, it is only in Ghana that  community studies have been documented. These studies have shown that Ghanaian children with Kwashiorkor fed on QPM recover. I have thoughtfully compared these with my own casual observations that Western Kenyan children, fed predominantly on a white hybrid maize staple diet continue to suffer from Kwashiorkor. The high infant mortality rate in Wetern Kenya is a crying shame, yet any possible solutions must come down to political will. When political will catches up with the reality on the ground the problem will receive the attention it deserves. The officials concerned with addressing malnutrition nationally then will be well advised to break down the national statistics for disease burden, poverty rates, and child mortality into regional figures. It will be important to identify the communities most afflicted and to apply the most intense programs within them.

Several reasons have been cited for the minimal undertaking of QPM research efforts on the African continent. One of these reasons is that many nations do not have the technical capacity to support such research. However, if Ghana can do it, why can't other African countries do it? Keep in mind that much of the hard scientific work that would facilitate such research has already been done. It seems more likely that the absence of such research efforts is attributable to the absence of coherent national development goals in many African nations. Such goals are rendered impossible because of the degree to which resources are commandeered for ethnic interests rather than national interests.

Leaders focus more on meeting the superficial needs of "their people" so that the tribal voting blocs on which they are dependent can get them back into office during the next political cycle. There really isn't much time or energy left to look into the more profound needs of their communities in the long-term, or to even think about other communities nationally. What this means is that ordinary Africans who want to see Africa change for the better have to learn to do the dirty work themselves, often without government support.

The African culture of poor leadership is bred in our homes. We must start taking responsibility for this culture: If there is something you can do to change Africa for the better, do it now, starting in your home. Don't just complain about "Africa's poor leadership." Leadership should start with you, dear reader. If you can't make the necessary sacrifice, why should you expect that somebody else will? Leadership arises from the people.

How Africa's maize turned white: a review

A while back, I read James McCann's book Maize and Grace: Africa's Encounter with a New World Crop, 1500-2000. Beautiful book! Any of you out there who can should grab a copy.

My favourite chapter in the book is "How Africa's maize turned white". It opens with the dramatic events that have characterized and shaped modern Africa, starting in South Africa i.e. mining, industrialisation, European settlement and male migrant labour. Maize is at the heart of all these events. However, whereas maize serves as the native South Africans' staple diet (in mealies and beer), for South Africa's commercial farmers, maize is a traded commodity used globally in industry and as cattle feed (and allied feeds).

According to McCann, native African maize (originally imported from South America during the Columbian era) expressed itself in very different ways on small peasant farms, displaying many colours. Up to the beginning of the 19th century, farmers could choose seed from their previous crop; they also had a variety of coloured maize varieties to choose from (e.g. Blue Flint, which they had by then christened "Blue Zulu"), but the arrival of hybrid maize changed all this. This was preceded by the discovery of diamonds at Kimberley in 1867, which led to an influx of migrant workers and capital, opening up the area for commerce and an increased demand for food. In the late 19th century White American Maize, which birthed the hybrid varieties that would revolutionize maize farming in both Southern and Eastern Africa, was imported. These new (hybrid) varieties were, in addition, high-yielding and utilized commercial fertilizer, making maize farming attractive to large commercial farmers.

While most of the world's maize crop is yellow, Africa produces mostly white maize. Chemically and genetically the 2 varieties are similar, although the yellow maize has a nutritional edge over the white maize because it contains the "carotene oil pigments responsible for the colour of yellow maize". Carotene is a precursor of Vitamin A. Most Africans prefer the white maize and refuse any other colour. In fact, when given a choice, they will pay more dearly for the white variety. This sharply contrasts with earlier Africans who selected "coloured maize ranging from crimson to blue to colourful mosaics of red, blue, yellow and orange." So how did this transformation occur?

This transformation is linked to the commercialization of maize that naturally followed increased demands for the crop. Maize became an exportable commodity which, for the purposes of the British starch and distillery industries, had to be homogeneously white. The South African crop could therefore compete on the international market, and get premium prices as a white homogeneous crop. In Southern Rhodesia, in an effort to force farmers to grow this homogeneous white crop, the cultivation of coloured varieties was outlawed. The flour mills also preferred the hybrid white maize because it was easier to mill, having a softer grain than the other varieties. One author mentioned in the book hints at another reason, divorced from the above two: "The real cause is the tendency of the native to imitate the white man, and that as the white man in Southern Africa eats only white mealie meal, the native thinks he ought to do so too". Contrary to this assertion, however, white South Africans had long identified maize as a "kaffir food".

McCann ends the chapter by reflecting on the political and economic forces inscribed by hybrid maize onto Southern Africa at the end of the 20th century: White farmers prospered while black farmers declined. Medical records from the 1920s and 1930s show that in colonial Basutoland "the incidence of pellagra and kwashiorkor increased in direct proportion to the rising percentage of maize in the diet".
