Assessing expected economic losses from wildfires in eucalypt plantations of western Brazil

چکیده

The increasing demand for pulpwood promotes the rapid expansion of eucalypt plantations over fire-prone savannas in western Brazil. Currently, large wildfires pose a real threat to these commercial plantations, disrupting supply chain. Forest managers lack site-specific quantitative assessments inform scale harvesting plans and cost-effective risk reduction programs. In this study, we combined wildfire likelihood estimates with potential fire effects assess stand-level expected economic losses across savanna enclave Here, used minimum travel time spread algorithm predict annual burn probability (aBP). loss was estimated combining pixel-level aBP associated forest value according raw material market value, management cost cash flow, rotation period. Young stands (< 2 yr) attained highest values, whereas intermediate-age mature (> 4 showed largest 400 US$ ha−1 yr−1). Our findings suggest that local should expect 1.75% terms provision, equivalent some 20 million yr−1. Fuel programs focusing on hotspots plus ignition prevention along interfaces would reduce plantations. addition, environmental policies related mitigation correct usage grasslands might be developed attenuate risk. This study implements methodological framework allow comparing alternative strategies South American tropical where revenue from systems is fundamental source income economies.

Managing soil fertility in eucalypt plantations in China

More than 1.5 M ha of eucalypt plantations have been established in south China, increasing by about 100,000 ha y. Productivity is uneven and low, only about 25-50% of the world average for eucalypt plantations. Most land available for eucalypts are degraded oxisols and utilsols which also are acidic, highly leached and deeply weathered. Phosphorus deficiency is very severe and its availability...

Economic Evaluation of Eucalypt Energy Plantations1

An evaluation of the economic feasibility of investment in a eucalypt energy plantation must involve an assessment of the costs of the various cultural practices (planting, weed control, irri­ gation), the costs of processing the standing tree into a usable form (logging costs, transportation costs, chipping, cutting to firewood length) and the returns expected from the sale of the pro­ cessed ...

High risk of plant invasion in the understory of eucalypt plantations in South China.

Eucalypt plantations expand rapidly out of their natural distribution zones, thus inducing a concern on their effects on biodiversity and ecosystem functions. We compare the understory plant diversity of 46 plots of eucalypt plantations, including early and later stages in rotation, with that of 21 plots of contrast vegetation, including other types of plantations and secondary shrub grassland,...
