impact of veld fires in ziim

Veld fires are a common phenomenon in the predominantly savanna ecosystems of Zimbabwe. Until now no studies have investigated the causes, and socio-economic and environmental impacts of veld fires in Zimbabwe. Yet such information is crucial for planning and implementation of fire prevention and control practices. The present study uses multiple sources of information including review of published literature, reports from regulatory agencies, informal interviews and field observations to address the following objectives; (1) to identify the key causes of veld fires in Zimbabwe, (2) to investigate the socio-economic and environmental impacts of veld fires, (3) to highlight management practices for the control of veld fires and (4) to identify research gaps on causes and management of veld fires in Zimbabwe. This review showed that the main causes of veld fires are anthropogenic. The impacts of fires are multifaceted and are a threat to the bio-physical, social and economic environment because of their trail of destruction and they directly impact all sectors of the economy. Impacts range from loss of livelihoods and income, psychosocial impacts associated with fatalities and family bereavement, loss of biodiversity and disturbance of the hydrological balance. It is very difficult, if not impossible, to prevent veld fires because, besides the negative impacts of veld fires, fire also play an important positive role in many Zimbabwean ecosystems. In view of this, fire management should move away from fire fighting to management practices such as early burning that reduces the negative impact, and enhance the positive effects of veld fires.
