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.

Country in the Pacific, Tuvalu remains without drinking water

Tuvalu, a small island country located in the Pacific Ocean, declared a state of emergency following a drinking water crisis. Officials said that in some areas of the country, drinking water stocks have ran out .

New Zealand’s Foreign Minister said that his country has worked with the Red Cross to send aid in Tuvalu. Two military aircraft C-130 type were sent to Tuvalu, carrying them on board two water desalination units and numerous containers containing water.

Secretary General of the Red Cross warned the people of Tuvalu not to drink water from wells. “This water is not good for consumption, we have already received several reports that the animals drank water from wells that have died,” he said.
