“…In Bolivia, Pinto and Alvarado (2011) observed a difference in perception of the problem of wildland fires were attributed to difference in land use practices. Cattle owners, thatch grass sellers and those practising bee keeping take wildland fire as a challenge because it affects their business most, while farmers who use fires for land preparation and as a source of nutrient (Goldammer 1993;Garren 1943;Jordan 1985;Saharjo 1995) will not view wildland fires as a challenge. Most farmers in Chakari suggested that most wildland fires were caused by human errors, or negligence, while a small percent cited natural causes.…”

Zimbabwe is among the most fire prone countries in Africa south of the Sahara. Annually over 1 million hectares of land are destroyed by wildland fires during the fire season which runs from July to November. Wildland fires are caused by several agents, cost huge socio and economic loses and are difficult to police. The objective of this study was to evaluate the causes of wildland fires, associated socio-economic impacts and challenges associated with policing wildland fires in Chakari resettlement area. Although the area studied was small compared to the whole country, the results showed typical challenges that are faced in many resettlement areas in Zimbabwe. The study used multiple sources of information including review of published literature, reports from regulatory agencies, questionnaires, interviews and field observations. The results from the study showed that 86 % of the respondents suggested that wildland fires are caused by human negligence and deliberate arson, 14 % suggested that wildland fires are caused by natural factors such as lightning and spontaneous ignition, while 6 % suggested that events such as vehicle and locomotive accidents and electron clouding of power lines cause wildland fires. The major human causes of wildland fires were cited as hunting and bee harvesting (84 %), burning of crop residues and land preparation (80 %), burning homestead surroundings to improve visibility (79 %) and deliberate arson was cited by 61 % of the respondents. Using the contingency valuation method, the estimated average income loss from wildland fires was US$1 408 ha −1 year −1 . The major challenges faced in policing wildland fires included poor community participation in fire related activities (69 %), absence of deterrent fines (64 %), complexity of the crimes (51 %), inadequate training (45 %) and lack of resources (40 %). Fire management should move away from fire fighting to prevention and sustainable practices such as early burning. In addition there is need for extensive training of communities on fire management and managing ignition sources. Policing of wildland fires can be improved through availing more resources towards policing, improved training, establishing partnerships with local population and leadership, and empowering traditional leadership to police wildland fires.

_____________________________________This state-of-knowledge review about the effects of fire on flora and fuels can assist land managers with ecosystem and fire management planning and in their efforts to inform others about the ecological role of fire. Chapter topics include fire regime classification, autecological effects of fire, fire regime characteristics and postfire plant community developments in ecosystems throughout the United States and Canada, global climate change, ecological principles of fire regimes, and practical considerations for managing fire in an ecosytem context.

“…Frequent fire is essential for maintaining the high species diversity and the vegetational structure. Fire also increases primary production in the community (Garren 1943, Christensen 1977, Schneider 1988). In the absence of fire the canopy may become denser and shrubs invade.…”
