Credits: Biovision-Infonet Run-off from catchment areas Although regions with low and erratic rainfalls appear to be unsuitable for rainwater harvesting, it has been proved many times that rainwater harvesting is the most viable water supply system in arid and semi-desert regions. Rainwater harvesting in dry regions is viable when the following aspects are considered and […]

Rainfall
Credits: Biovision-Infonet Although it is known that clouds can be seeded with chemicals to produce rains, the practice is expensive and unsustainable. It should therefore be realized that rainfall varies from region to region and from one year to another beyond peoples’ manipulation and interference. All fresh water comes from rains, including water in deep […]
The Water Cycle
Credits: Biovision-Infonet Every living creature and vegetation must have water in order to survive. Only 3% of all water on Earth is fresh water and 68% of the water is frozen ice on the North and South Poles. All humans and most animals as well as nearly all vegetation can only survive on fresh water […]
Rainwater Harvesting
Credits: Biovision-Infonet Introduction Rainwater running off land surfaces can be harvested, stored and utilized using a technique called rainwater harvesting instead of being wasted in rivers, lakes and the sea. Rainwater harvesting consists of 5 components: Rainfall Catchment areas, also called watersheds, onto which the rainwater falls.

Potato Seed Production
Credits: Biovision-Infonet Introduction Second only to maize, “Irish” potatoes play a very big role in the Kenya food security situation. Potatoes can be grown within a growing period of 3 months, produce good yields of highly nutritious food and be stored for some months under the right conditions. However growing potatoes in mixed cropping systems […]
