The more types of plant and animals present in the environment, the healthier that environment is for both human and animal populations. The variety of animal and plant types, which is referred to as biodiversity, is reduced when conditions develop that make it impossible for some species to survive. Such conditions can be created by excessive use of chemicals aimed at killing weeds or pests, which also end up killing species that are beneficial to human beings, animals and agricultural crops.
These beneficial species include bees,
butterflies, moths and other pollinators. Within Laikipia County, there are a number
of Projects focusing on promotion of biodiversity in different ways.
Maintaining high levels of
biodiversity has many benefits. For example, elimination of harmful chemicals
results in increase of pollinators such as bees and other useful insects. This
enables more people to get involved in activities relying on some of them such
as bee keeping (apiary) for income. The quality of trees and other vegetation
also improves because pollination ensures the production of better adapted
varieties of plants.
It is important to note that
biodiversity refers not only to plants and animals available in our
surroundings but also organisms that live in the soil such as earthworms and
even micro-organisms such as bacteria and fungi. These microbes aid in the
decomposition of plant materials to release useful nutrients for plants.

Another factor that is threatening
biodiversity is climate change. Climate change is the significant change of the
average temperatures over period longer than 30 years, causing changes in weather
patterns and a (slow) rise in sea level, among other impacts. According to the
National Climate Change Action Plan (NCCAP), key climate change impacts for
Kenya are drought and water scarcity, flooding and sea-level rise.
Research suggests that temperatures
will continue to increase, and the frequency of hot days and nights will rise.
Precipitation is expected to increase in some areas, with the largest rise in
rainfall occurring in the highland and coastal regions.
However, the greater part of the
country comprising the arid and semi-arid regions is expected to become
significantly drier. When climate patterns change, it is expected that plants
and animals species which only survives on cooler regions will disappear while
new species suited to warmer climates will replace them.
