The Problem with Dependence on Rainfall in Parts of Africa

It is no longer news that parts of Africa are ravaged by extreme droughts and devastating food shortages. In most of these places, farming is the main stay of the economy.

Over the years, farmers in Africa – both small and large scale have depended on rainfall as the source of water for their large expanse of farmlands. But things are about to change.

With the current change in the world’s climate, leading to infrequent rainfall and unusually long dry seasons, farmers all over the world need to re-position themselves in order to remain productive.

One major way of ensuring they remain in the game is look for alternatives to rainfall by using irrigation in providing water for their farms. The damages already recorded in the severe effects of drought in many parts of Africa really far outweigh whatever costs implementing an irrigation system could take.

Sometimes, the costs involved may not even be astronomical in some environments considering that some farmlands are located beside large bodies of water, like dams, lakes or rivers.

However, the topography of Africa, and the fact that so many of these places that really need help are usually remote, makes them difficult to access for aid during difficult agricultural seasons.

The truth is that African governments need to make long term plans for providing rainfall alternatives for farmers. Large scale farmers also have to learn modern ways of irrigation used in other parts of the world.

The times when rainfall determines crop yield in farms is becoming a thing of the past, and farms all over the world need to rise up to the challenge of drought and food scarcity.

How Effective Is Water Treatment for Wastewater?

Treatment of wastewater involves the removal of both organic and inorganic matter from used water, thereby making it appropriate to be used again. During this recycling process, the wastewater usually goes through filtration, disinfection and separation processes that remove both organic matter like pathogens as well as inorganic matter such as chemicals.

Depending on the quality of water required, the processes involved in its treatment may vary. There could just be the primary treatment that only screens the water but offers no treatment to it.

The secondary and tertiary treatments provide more advanced treatments. The tertiary water treatment method for example, can eliminate impurities from sewage entirely. But the technology required for the process is still a bit expensive because of the equipments needed. It also requires a very high level of specialized knowledge, which may not be present at all times.

The method adopted in the treatment of water also depends on the industry in need of the water. For those that work with high levels of toxic substances, they have to use the more advanced water treatment methods; while others will implement the simpler procedures.

Today, we still experience pollution in our environment as a result of the absence of suitable methods for treating water. And so there is still the need to develop more efficient ways of recycling water in our ecosystem.

The new water recycling methods will have to be economical, efficient, environmentally friendly as well as easy when in use.

Were the 2012 Olympics a corporate parade under the shadow of guns?

The Olympics have come and gone and many claim that they have done little to help give local economies a push. While government official claim that the impetus given by the 2012 games would mean a better and more vibrant economic future for London and the surrounding areas, independent tourism companies and hotels claim that the ‘feel good’ effect has been almost negligible.

Businesses already reeling under the effect of the tough economic times say that the Corporate Olympics have done next to nothing for small local businesses in the short or long term. So the question still lingers if the Olympics really is just a corporate parade and one under the shadow of guns.

There are plenty of reasons to believe that it is and while everyone around the globe has the greatest of respect for the athletes who toil away all their lives to achieve their Olympic dreams, one wonders if they are just small pawns in the bigger plot. They definitely seem to be the ones who are doing all the hard lifting for little gain while the suits and ties in the corporate houses ride on their backs while dangling the carrot of ‘glory’ to fill their own pockets.

People are starting to question the ‘Olympic Spirit’ when its committee is willing to freely promote the likes of BP as ‘sustainability partners’ after the mess their oil spills have caused and Dow Chemicals, responsible for thousands of deaths and tragedies in the Bhopal incident in India.

Where is the Olympic spirit that cherishes humanity and its great ethics when it comes to choosing corporate partners? Obviously money seems to be the biggest magic wand that will get you whatever you want with the Olympic Committee. No one expects the Olympics to take political stands, but people do hope that the games live up to their own billing.

Add to this the fact that this has been the heaviest militarization of London since WWII and one wonders if this is what ‘celebrating humanity’ is all about!!
