While generating optimal land use configurations, the model enables an assessment of the market and nonmarket tradeoffs associated with different land use priorities.

Forests are being depleted rapidly as adoption of sound forest management practices is still in the incipient stage [ 12 ]. Although this work was reviewed by the United States Environmental Protection Agency and approved for publication, it may not necessarily reflect official agency policy.

The remaining profits are dd to go to the government via a royalty mechanism that does not affect harvest decisionmaking. However, as a result of diminishing returns from management effort for multiple activities within the same stand, landscape-scale multiple use planning is perhaps most efficient re each stand has a unique use [ 13 ].

We drew upon previous efforts to estimate the spatially explicit profitability of logging [ 15 — 17 ]. Each stand has an annual harvestable area llei in hectares. Zoning decisions in public forests, assuming that logging is the only revenue-generating activity, will create opportunity costs in terms of lost NPV. Lentini would like to thank D. The software used in the analyses was GAMS In our study, we consider community use and biodiversity 206 as possible alternative uses.

The datasets used span the entire Brazilian Amazon, implying that the analysis can be repeated for any public forest planning effort within the region.

Percentage of stands harvested within Faro State Forest with an increasing number of stands converted to other land uses from current logging centers a and from closer urban centers b. Figures 5 c and 5 d show the frontier by applying differentiated weights for stands under these alternative uses, respectively, for community use and biodiversity conservation, using as a starting point the same NPV in the UL scenario.

Every three years the interval represented byBrazilian law requires independent audits of concessionaire performance within the concessions.

The usefulness for direct beneficiaries and for the society of stands set aside for land uses as community use and biodiversity conservation could be enhanced by assessing spatial zoning configurations which take into account the degree of connectivity among stands with the same land use alternative, which could be achieved by adding the appropriate constraints.

In the first set of model runs that follow, we first assume that the spatial distribution of mills remains static. We then use the NPVs in the different scenarios simulated to determine the marginal opportunity arising from decreasing the area logged due to increasing requirements for alternative land uses. The model developed in this study is not intended to replace these efforts but, rather, ve incorporating data generated from these surveys, given planners a method to easily visualize alternative planning landscapes.

In either situation, expressed in 6represents the policy-driven minimum number of stands or the minimum score across alternative nonlogging land uses. We begin by establishing the basic selective logging timber supply problem, where the decision variables determine the amount of volume per ha to harvest.

After developing the model conceptually and discussing the data used within the model, we demonstrate the model on aha public forest. These studies created maps identifying forests financially profitable for logging, based on wood prices and logging costs i.

While generating optimal land use configurations conditioned upon policy objectives, the model enables an assessment of the market and nonmarket tradeoffs associated with different land use priorities. From ed map, we estimated the harvestable volume of each timber value class i. The authors are also grateful to two anonymous reviewers for their valuable recommendations. Some data and suggestions were also provided by L. Brazilian regulations establish that management decisions 111284 each public forest will be guided by a management plan, which will be generated based on surveys in each public forest, including forest inventories, designated important sites for biological conservation and tourism, and the location and needs of traditional forest dwellers.

Volume harvested within Faro State Forest by timber value class with an increasing number of stands converted to other land uses from current logging centers a and from closer urban ee b. Figure 6 b shows the same results for areas assigned to biodiversity conservation.

Obviously, as the number of stands assigned to alternative land uses such as biodiversity conservation and use by communities is increased, the number of stands logged, timber volume harvested, and profits from logging decrease. In the remaining area, only high-value species would be logged.

Fourth, at the landscape level, this model can help to determine the optimum level of timber production and spatial distribution of alternative land uses from public lands within a given region by taking into account future production trends of the logging industry.

If the stand is harvested, the timber will travel to at least one of mills located in logging centers denoted by. In the two multiple use scenarios investigated, the potential for logging was considered equal to 1 for any stand in which the estimate of ce profitability was greater than zero, and zero otherwise. The curves traced out mainly Figures 5 a and 5 b due to the similar comparative scale are useful to assess the effects of nonlogging land use alternatives over the NPV generated by logging.

As well-planned and executed harvesting on public lands is intended to replace illegal logging on these lands, this capacity estimate is a reasonable starting point for analysis until better data become available. Harvests are assumed to be performed from current logging centers.

Three competing land uses were considered: In a full-blown application of the planning model within an actual forest planning context, it would be possible to use participatory techniques from multicriteria decision analysis to determine the relative weight of competing land uses.

It is important to note that, because of data limitations, prices and costs are assumed to 0206 constant throughout the analysis, even though regional and local timber markets will be affected if large quantities of legal timber become available. The experience across other countries shows that this assumption is extremely optimistic as governments have generally captured only a small proportion of the total rents [ 2829 ].

Table of Contents Alerts. To 112284 public forest planning lfi, we combine spatially explicit data on logging profits, biodiversity, and potential for community use for use within a lel planning optimization model.

In this section, we report a series of results from 111284 model applied to FSF. In other words, the economic model maximizes the annual profits originated from the annual allowable area for harvest of The potential of each stand for each land use is assumed to be known and is denoted by.

Meanwhile, our estimates of government receipts should be viewed with caution. Second, it can be used to estimate the revenues that can be generated from concessions and the taxes that can be collected by government through a nondistortionary royalty mechanism.
