Environmental implications of cell phones penetration and disposal in Kenya
(International Journal of Computers & Technology, 2014) Wabwoba, Franklin; Sakwa, Thomas; Mbugua, Samuel; Kilwake, Humphrey Juma
Kenya has over six million active mobile subscribers who may at some point want to replace or get rid of old mobile phones. A big number of the mobile phones were recently switched off for not being genuine without a prober mechanism being put in place for the disposal. If every affected individual or otherwise disposed off phones by throwing it away then there could a serious ecological disaster in waiting. Cell phones are hazardous materials because of electromagnetic radiation and electronic composition. They have substances such as antimony, arsenic, beryllium, cadmium, copper, lead, nickel and zinc which belong to a class of chemicals known as persistent toxins. These toxins pollute and remain in the environment for long periods. There are ill-effects of wireless and telecommunication devices on the environment are disastrous. The increased use of high resolution LCD screens leads to a potentially devastating environmental challenge. There is no clear policy frame work on e-waste management with a special focus on used mobile phones in the country. A proper disposal mechanism of wireless and telecommunication devices is a necessity in Kenya
ENVIRONMENTAL IMPLICATIONS OF CELL PHONES PENETRATION AND DISPOSAL IN KENYA

ABSTRACT Kenya has over six million active mobile subscribers who may at some point want to replace or get rid of old mobile phones.

Green ICT implementation in developing nations: personnel perspective
(Scholars Press, 2014) Wabwoba, Franklin; Mbugua, Samuel
Though ICT is contributing to the economy associated with innovations, inventions and rapid development in almost all aspects of human life, it is also responsible for climatic degradation. The rapid increase of ICT usage means more costs of doing business, energy consumption, and more environmental challenges. The rapidly changing technology and lack of their understanding has put a lot of pressure on both management and ICT personnel to implement them on a trial and error manner. This has limited the gains meant to be obtained from green ICT. The lack of appropriate alignment between the ICT personnel capacity and the workplace readiness poses more environmental and unsustainable resource utilization challenges. The book was informed by the G-readiness model. It discusses the green ICT technologies, the personnel awareness of green ICT, green ICT maturity, and workplace readiness for green ICT and the perceived barriers to green ICT implementations. It explains the extended G-readiness assessment and G-alignment models that when well applied are bound to enhance the implementations of green ICT. It is an excellent book for undergraduate and graduate studies for Green ICT courses.
