Abstract

Invasive plants are a hazard in the tropical dry forests and rangelands of East Africa. Although often not reported, they have increasingly created disasters that have affected the environment and socio-economic wellbeing of communities inhabiting these dry regions. This paper reports on the key invasives in the drylands of Kenya and Tanzania and their effects, and suggests some disaster risk reduction (DRR) strategies. The study was largely based on secondary data analysis and supported by surveys in the affected drylands. The findings show ten key invasive plant species that affect the drylands. Their disaster-effects vary and include: causing the death of livestock by poisoning and destroying livestock foliage, accelerating biodiversity loss via suppression of native plants, to increasing diseases by offering a breeding ground for mosquitoes and other insects that carry ailments like nagana and sleeping sickness.


The DRR initiatives include (1) having a prudent land use system that discourages activities like unplanned burning of drylands, (2) assessing and monitoring phytosanitary risks associated with introduced plant species, (3) strengthening national and local institutional capacities that enhance invasive species awareness and preparedness for disasters, and (4) enhancing early warning systems related to plant invasion.
