This paper aims at evaluating the impacts of climate change on land use patterns in Brazil. To this purpose, we specify and estimate an econometric land use model to assess how climate variables affect land allocation decisions according to three types of use: cropland, pasture and forestland. Based on the econometric model estimates, we then simulate how farmers will adapt their land use choic...
This study used panel data models with spatial error correlation to analyze private tree planting in the US South from 1955 to 2003. Controlling for statewide, fixed effects allows us to disentangle the effect of spatial interaction from that of state heterogeneity and omitted variables. The results show that there is significant spatial interdependence among the southern states in private tree...
Escalating wildfires on forestlands in recent years have resulted in statutory changes in redefining the liability for landowners in using prescribed fires. This study summarized these reforms in recent years. While in some states there is still strict tort liability for damages from prescribed fires, eighteen states have reduced the liability burdens on landowners with simple negligence rules,...
Despite the large implications of the use of tropical land for exports ("land absorption") on ecosystem services (ES) and global biodiversity conservation, the magnitude of these externalities is not known. We quantify the net value of ES lost in tropical countries as a result of cropland, forestland and pastureland absorption for exports after deducting ES gains through imports ("land displace...
Beginning in the 1990s, private ownership in Maine forestland shifted from a number of corporate owners to a patchwork of timber investment management organizations (TIMOs) and real estate investment trusts (REITs). This transformation reflected restructuring trends in the paper and pulp industry. During this same period, forest certification increased to levels that today make Maine one of the...
The southern United States is susceptible to wildfire, from its climate, growing seasons, lightning frequency, and decades of fire suppression. With much known about wildfire’s biophysical risks, less is understood about sociodemographic obstacles, including race, income, and education. Blacks in the rural southeastern United States are typically among the most marginalized Americans and least ...
This paper considers potential cellulosic ethanol production from Southern slash pine (Pinus elliottii) plantations. The net energy balance (NEB), emissions and associated environmental impacts, unit cost of ethanol production, and associated changes to forest land values are calculated and preliminary results are given. The NEB is found to be positive at 2.2, meaning that for every unit of ene...
In the context of global change, it is essential to promote rational development and utilization land resources, improve quality regional ecological environment, harmonious human nature for sustainability. We identified use/land cover types in northern China from 2001 2018 with ENVI images ArcGIS software. Meteorological data were selected 292 stations China, potential evapotranspiration was ca...
Past Land Use Cover (LULC) transitions analysis at the sub-continental scale of West Africa revealed spatial reallocation, i.e., simultaneous losses and gains LULC categories different locations. We applied component approach to separate total change into three major components, quantity (net change), exchange shift (allocation change) as a way analyse such reallocation identify paired that acc...
