The Brazilian government seeks to manage public forests as a critical component of forest-based sustainable development through implementing a complex balance of multiple and often competing uses [ 3 ]. Abstract Logging in natural forests is a vital economic activity in the Brazilian Amazon.

We also estimated the rent distribution between concessionaires and the government. The model can be used to investigate the impacts of concessions from public forests on the local demand and supply for timber in a given region. Different fucosyltransferase FUT genes were also identified in adjacent and tumor tissues, and two HCC cell lines with different metastatic potential. The same explanation given for the NPV curves in the last section is valid in explaining why MOCs for community use are larger than MOCs for biodiversity conservation since areas with potential for community use in the case of FSF are located near to roads and rivers and have higher profitability for logging.

Our assumption in the model is that the government is able to use an unspecified nondistortionary royalty instrument that does not influence harvest behavior to extract rents to the point that concessionaires just earn profits equivalent to those of operating legally on private lands. All these curves show that MOCs increase when a large proportion of FSF is used for uses other than logging since more profitable stands are increasingly assigned to these uses.

This is important for planners because it can accommodate values of noncommercial land uses in a more meaningful way. In a given public forest, government seeks to maximize profits from logging.

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.

Each stand has an annual harvestable area denominated in hectares. Production possibility frontiers for logging and livelihood systems a and logging and biodiversity conservation bassuming stands are weighted equally for nonlogging land uses within Faro State Forest; production possibility frontiers considering different weights among stands for nonlogging land uses, for logging and livelihood systems cand logging and biodiversity conservation d.


The software used in the analyses was GAMS Processing would be performed by mills located in only three centers: Inthe Brazilian Forest Service SFB concluded the first inventory of public lands, a starting point for detailed land use planning within public forests.

The forest concession in public forests in Brazil started to be legally handled through the “Law for the Management of Public Forests”.

Datasets and technical assistance were provided by R. We simulated the lsi possibility 1184 PPF and investigated the tradeoffs among different land uses for three scenarios using existing logging centers and also when the centers move to cities closer to FSF: The potential of each stand for each land use is assumed to be known and is denoted by.

As well-planned and executed harvesting on public lands is 11824 to replace illegal logging on these lands, this capacity estimate is a reasonable starting point for analysis until better data become available. Currently, annual profits from logging represent one of the primary variables considered by the Brazilian Government in decisionmaking to grant concessions in public forests. Alternatively, the planner can impose a minimum score to be achieved for a given land use by assigning different weights for each land use.

The le forest concession, through the payment for the sustainable use of forest products and services, is a way of indirect management that can be applied to National Forests and other types of public forests which are not designated to community use or protected areas of “full protection” category. The Brazilian government currently implements a concession 1128 to exploit timber harvesting on national forestry reserves.

Published in Oncotarget V7N38Sep 20, 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.

Thus allowing federal, state and local governments to grant to private actors the right to sustainably exploit the goods and services present in public forests. FSF is covered by dense forests and displays little evidence of use and human occupation in the extreme eastern and southern portions [ 14 ]. The volume harvested is constrained by the available merchantable timber leo in the forest and the milling capacity of the logging centers surrounding the public forest.

Mass spectrometry MS analysis showed pronounced differences of the N-glycosylation patterns and fucosylated N-glycans between the adjacent and tumor tissues.

In the case of community use, we assigned to stands in which older forest fires were identified — a weight equal to lri the weight assigned to stands indicating more recent forest fire activity — equal to 2 and 3, resp. License CC BY 3.

The parameter is assigned a priori to be either binary 0, 1 or some other score assigned by the public planner, in the case the planner has information about the relative value of different stands for a given land use alternative.

Altered levels of FUT8 in HCC cell lines significantly linked to the malignant ,ei of proliferation and invasion in vitro.

Figures 2 and 3 show what happens to the number of stands assigned for logging and harvested volume when logging is performed by firms leu in the current logging centers Figures 2 a and 3 a and if mills move to closer cities Figures 3 a and 3 b. The Brazilian government estimates that up to 13 million ha of forest concessions could be established within the first 10 years of implementation of the Public Forest Management Law PMFL.

Equation 5 imposes a constraint guaranteeing no more than a single land use choice per parcel. Volume harvested within Faro State Forest by timber 112844 class with an increasing number of stands leo to other land uses from current logging centers a and from closer urban centers b. The major challenge facing public planners now lies in allocating land across multiple uses to meet multiple objectives, often with little information about socioeconomic and biological conditions.

Our model is able to generate simple estimates of government rent capture, assuming concessionaires are only able to capture normal profits.

Harvests are assumed to be performed from current logging centers. The GoB estimates that approximately 13 million hectares in the Amazon will be opened to public use over the first 10 years of the plan.

The remaining stands cannot be harvested due to high slopes.
