WARNING: This is Version 1 of my old archive, so Photos will NOT work and many links will NOT work. But you can find articles by searching on the Titles. There is a lot of information in this archive. Use the SEARCH BAR at the top right. Prior to December 2012; I was a pro-Christian type of Conservative. I was unaware of the mass of Jewish lies in history, especially the lies regarding WW2 and Hitler. So in here you will find pro-Jewish and pro-Israel material. I was definitely WRONG about the Boeremag and Janusz Walus. They were for real.

Francistown – The vegetables Omphemetse Monyi sells at the Francistown bus rank come from 400 kilometres away in South Africa. One approach to development might seek to replace her suppliers with local farmers, but Southern Africa’s water managers are considering the merits of reinforcing a regional trade in “virtual water”.
Depending on the season, Monyi sells watermelons, tomatoes, potatoes, onions from the back of her truck. The 44-year-old makes the trip to South Africa each week to purchase vegetables for sale; she says she buys about 10,000 pula worth of stock ($1430), and makes a profit of between P3,000 and P4,000.
It’s not just informal traders who bring fruit and vegetables to northern Botswana from elsewhere. The supermarkets down the road from her stall also import their produce from South Africa. It’s part of a trade in virtual water, though Monyi doesn’t think of it that way.
“For those [Botswana farmers] who do harvest and sell, they do not produce the quality that we get in the South African farms. Take potatoes for example, they will not be cleaned well and not packaged according to size,” she says.
Until recently, one of the first questions economists might ask would be, why can’t the farmers in Botswana compete? The answers might include disadvantages in terms of good soil and sufficient water, or capital to allow them to mechanise production and put more land under cultivation. The recommendation might be to address these problems to help local farmers gain a foothold in their local market.
But some disadvantages cannot readily be overcome with money or training. Enriching soil, for example, is a slow process, but possible.
Increasing available water presents its own challenges. Irrigation schemes can be prohibitively expensive to construct and maintain; the high temperatures and low humidity in northern Botswana can mean significant amounts of precious water are lost to evaporation. When these costs are factored in, even irrigation may not allow local farmers to produce vegetables or fruit at a competitive price.
David Phillips an independent consultant and researcher based in Namibia, explains that countries can use virtual water to strategically enhance their overall access to fresh water.
“Perhaps the best examples of this are Israel and Egypt, both of whom import large quantities of foodstuffs and other items containing virtual water. Israel for example uses about 2.2 cubic kilometres of fresh water annually but imports about three times this volume every year in virtual water form.”
The concept of virtual water means thinking of an agricultural product – or other commodity – in terms of the amount of water required to produce it.
Due to richer soils, lower temperatures and evaporation, and better farming techniques, a thousand litres of water used in a farm along the South African stretch of the Limpopo will produce more tomatoes or sugar than the same amount of water used somewhere upstream in Botswana, where the river runs through more arid countryside.
Phillips is one of those involved in developing guidelines for basin-wide management of transboundary rivers in the Southern Africa region.
He explains how virtual water can give managers additional flexibility in negotiating allocation of water resources. The idea is that certain countries have optimal conditions for growing food; a benefit-sharing approach is to maximise production of crops per unit volume of water.
“Where these countries attain high levels of productivity, it implies a global saving of water compared to producing the crops elsewhere and this is important if we are to continue to feed the world’s growing population,” Phillips said.
A benefit sharing approach to local economic development and food security along the Limpopo River recognises that these advantages can mean greater productivity and food security at lower cost for everyone: consumers in Botswana can make virtual – optimum – use of water if the farming is done in South Africa.
There are many other factors to consider, including the livelihoods of local farmers: virtual water is a concept that policy makers in river basin organisations are still working to grasp in order to see how they stand to benefit.
During a June brainstorming session of the Limpopo Basin Technical Committee held in Francistown, Botswana, water managers from throughout the basin were still cautiously assessing how benefit sharing might work.
“We need to build confidence first before we can say anything on this issue,” the delegation from Mozambique said.
“We will have to look at the cost-benefit to the country,” was all South Africa’s delegation would say.
Tracy Molefi-Mbui, River Basins Coordinator at the International Office in Botswana’s Ministry of Minerals, Water and Energy Affairs said the question of how the trade-offs will work in the full social, economic and political context of a transboundary river basin is not yet clear.
“If a country says, I will forgo this resource so that country B could produce this amount of products, how will that country benefit economically? Its applicability is still remote because we have not fully comprehended it,” she said.
Like any other decision making tool, Molefi-Mbui said, countries will need facts on the value of the system in order to “play our cards right as per the findings of the studies. It is complicated by the fact that [the trade-offs are] not even just between the countries, but also between provinces within a country.”
As the benefit-sharing concept is developed by the Southern African Development Community’s Water Sector, the hope is that it will become another concrete example of the regional body’s objectives, including sustainable collective development, harmonisation of political and socio-economic policies, and interdependence of member states.
