Insuring Southeast Asian commercial forests: Fire risk analysis and the potential for use of data in risk pricing and reduction of forest fire risk

The author uses his own data gleaned from over 10 years of commercial forestry insurance across the world to propose that despite a low intrinsic fire risk across most of Southeast Asia, especially Indonesia, commercial fire losses are unacceptably high, and could be reduced substantially within the current financial legal and political framework within which forestry companies operate. Opening with a statement about the dearth of forest fire loss data in the commercial sector, it is observed that the consequent inability of general insurers to estimate the rate of fire loss leads to very low insurance participation in forestry within Indonesia. A summary is then provided of the financial and environmental benefits of insurance participation in commercial forestry were this situation to be changed. A short discussion on risk perceptions is introduced to make the point that without reliable commercial forest fire loss data, risk perceptions of fire exposure in Southeast Asia by the financial sector, including insurers, is a barrier to risk transfer and investment. While real fire risk and perceived fire risk for Indonesia seem at present to be in agreement, the paper challenges that this should the case. Comparisons are made with different parts of the world with the knowledge that, in commercial terms, plantations in the low latitudes behave similarly everywhere in terms of fire causes, fire propagation factors, and characteristics of plantation or managed mixed forest fires. A review of the fire sizes within commercial forests is a good indicator of the efficiency of fire management strategies, and profiles from a high fire risk territory and Indonesia are compared. Using commercial and unidentified data the author then demonstrates that commercial growers in Indonesia have a high annual rate of forest fire loss and may also have a significant catastrophe fire exposure. This ‘cat’ exposure is far greater than for equivalent plantations in clearly higher fire risk environments. These conclusions are and should be discussed with forestry companies to change attitude and investment levels. Practical points for improved plantation fire management are made along with comments about the resources required. A parallel discussion then reviews fire risk assessment and management by the insurers to prevent their own ‘forest fire’ losses if they are to get further involved with the provision of Indonesian commercial forest risk transfer. The explanation of how insurers price risk within a portfolio helps identify the specific data needed for a proper risk management strategy to be developed.     

Evaluation of Central North American Prairie Management Based on Species Diversity, Life Form, and Individual Species Metrics

Abstract:  Reintroduction of fire and grazing, alone or in combination, has increasingly been recognized as central to the restoration of North American mixed-grass and tallgrass prairies. Although ecological studies of these systems are abundant, they have generally been observational, or if experimental, have focused on plant species diversity. Species diversity measures alone are not sufficient to inform management, which often has goals associated with life-form groups and individual species. We examined the effects of prescribed fire, light cattle grazing, and a combination of fire and grazing on three vegetation components: species diversity, groups of species categorized by life-form, and individual species. We evaluated how successful these three treatments were in achieving specific management goals for prairies in the Iowa Loess Hills (U.S.A.). The grazing treatment promoted the greatest overall species richness, whereas grazing and burning and grazing treatments resulted in the lowest cover by woody species. Burning alone best achieved the management goals of increasing the cover and diversity of native species and reducing exotic forb and (predominantly exotic) cool-season grass cover. Species-specific responses to treatments appeared idiosyncratic (i.e., within each treatment there existed a set of species attaining their highest frequency) and nearly half of uncommon species were present in only one treatment. Because all management goals were not achieved by any one treatment, we conclude that management in this region may need refining. We suggest that a mosaic of burning and grazing (alone and in combination) may provide the greatest landscape-level species richness; however, this strategy would also likely promote the persistence of exotic species. Our results support the need to consider multiple measures, including species-specific responses, when planning and evaluating management .
