Description

  The present invention relates to a system and method for supporting a business related to forest restoration and forest cultivation.

  It has been a long time since the reduction of carbon dioxide (CO2) was screamed as a countermeasure against global warming, but as part of that, we focused on the carbon dioxide absorption capacity of forests, stopped reducing the area of the forest, and started the maintenance and development of forests. A forest development project is being developed. In addition, there is also known an emission trading system that converts and uses the amount of carbon dioxide absorbed by forests for the trading of emissions credits stipulated in the Kyoto Protocol in order to achieve carbon dioxide reduction targets (for example, Patent Document 1). 2).

  On the other hand, the Forest and Forestry White Paper (Non-patent Document 1) of the Forestry Agency outlines the 2013 forest and forestry policy based on the importance of demonstrating the multifaceted functions of forests and the sustainable and healthy development of forestry. Based on the basic plan for forestry and forestry, etc., taking necessary financial measures, etc., establishing a well-organized forest management, guiding to diverse and healthy forests, promoting global warming prevention measures and adaptation measures, Recovery from disasters such as the Great East Japan Earthquake, conservation of national land, development and dissemination of research and technology for the regeneration of forests and forestry, promotion of mountain villages that support forests, public participation in forest creation and diverse use of forests It is going to work on measures such as promotion of

  However, it takes a long time and a lot of money to maintain and nurture forests, and not only the efforts of national and local governments but also the end of the above measures, the creation of forests with the participation of the public (Morizukuri) and promotion of various uses are indispensable. The use of forest emission trading systems such as Patent Documents 1 and 2 encourages the participation of private companies, but there are concerns that only companies that have been assigned a carbon dioxide reduction target will be interested. In particular, many forests were lost in the stricken areas, but there are many lands that have been left untouched. There are many places that must be diverted to land, and as a result, as much support as possible from various directions is necessary for the reconstruction and development of forests.

  Therefore, in view of the above-described problems, the present invention aims to provide support for a business entity that performs forest reconstruction and cultivation, and to construct a forest reconstruction support system that allows more people to participate. And

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention (hereinafter referred to as embodiments) will be described in detail with reference to the accompanying drawings. Note that the same numbers or symbols are assigned to the same elements throughout the description of the embodiment. Further, the arrows between the functional blocks indicate the data flow direction or the process flow direction.

  FIG. 1 is a diagram illustrating a basic concept of a forest reconstruction support system 100 according to an embodiment of the present invention. In the forest reconstruction support system 100, the owner of the land to be reforested or the person who has been entrusted with the owner of the land forms a business entity (hereinafter referred to as the forest reconstruction business entity 10). This is a system for supporting the business in which the entity reconstructs (regenerates) the land 30 to be reforested as a forest, or newly constructs and nurtures it. The forestation target land 30 is, for example, a mountain or land rough due to a disaster or resource mining, an idle land, an abandoned farmland, etc., and includes not only the land that was originally a forest but also land that can be converted to forest. Shall be. The forest reconstruction support system 100 increases the value by effectively using the land 30 to be reforested, gathers various investors (including donations), and uses new forests that are not confined to the conventional concept of forests. It aims to provide.

  First, the forest reconstruction training business unit 10 creates a forest reconstruction training plan 40 (forest management plan) and inputs it to the forest reconstruction training support system 100. A forest management plan is primarily a plan related to forestry based on a long-term policy on forest management, which defines the current status of the target forest, thinning and main cutting operations, logging, afforestation, and childcare implementation plans, etc. However, here it means not only forestry but also management of the forest in a broader sense, and afforestation based on land information (information on location, area, topography, soil, sunshine conditions, etc.) and the environment of the land It shall include map information of possible sections (forestation section map information).

  In order for forest management to be effective, the cost-effectiveness of investments for forest development and maintenance is important, but attractive values that many investors are interested in are necessary. Therefore, the forest reconstruction support system 100 includes a forest value evaluation unit 110 having a mechanism for numerically evaluating the value of the forest and providing “visualization” of the evaluation value.

  Forest value includes the value of biomass (meaning organic resources derived from living organisms) when forests are regarded as timber resources and fuel resources, the value of CO2 absorption when viewed as CO2 absorption resources for global warming countermeasures, And disaster prevention measures or water conservation, recreational environment conservation, biodiversity conservation, etc., there is disaster prevention / environmental conservation value. The commercial value such as the aesthetic value brought about by the beauty of the afforestation pattern, the tourism value of the forest as a tourism resource, and the advertising value as an advertising resource that uses the forest for PR of the region and companies is evaluated. .

  For this purpose, the forest value evaluation means 110 includes an afforestation pattern value evaluation unit 111 that calculates and evaluates commercial values including the aesthetic value, tourism value, and advertisement value of afforestation patterns. In addition, the forest value evaluation means 110 includes a CO2 absorption amount value evaluation unit 112 that is important for securing the commercial value of the forest. Further, since the cost for nurturing and maintaining the forest is an important management factor, a nurturing / maintenance cost evaluation unit 113 that calculates the cost as an estimated evaluation value is also provided. Furthermore, in addition to the commercial value as described above, a disaster prevention / environmental conservation value evaluation unit 114 is provided for evaluating the value of forests as public resources such as disaster prevention and environmental conservation. However, because the forest reconstruction support system 100 aims to nurture and preserve forests, it excludes the assessment of biomass value that captures forests as timber resources and fuel resources (however, it includes harvests from fruit forests, etc.) May be)

  Then, the forest value evaluation means 110 determines the investment amount for forest reconstruction, cultivation or creation based on the comprehensive forest value calculated from the above evaluation items, and recruits investors according to the investment amount. , Accepting investments. In addition, since specific data (land data, afforestation section map, etc.) of the forest reconstruction and development plan is disclosed, investors themselves can propose afforestation patterns or evaluate the proposed afforestation patterns. The value of afforestation patterns differs from the CO2 absorption value and disaster prevention / conservation value, which are almost uniquely determined by the area of the forest and the surrounding environment, and the evaluation increases with ideas, and investment can be solicited based on the evaluation.

  Also, afforestation patterns can result in beautiful (or unusual) scenery and can be a tourism resource. If a beautiful (unusual) afforestation pattern can be a tourism resource while maintaining the functions of the forest, it is possible to think that the evaluation of the forest will be high. For example, “rice field art” is an example of a new tourism resource that contributes to regional revitalization while maintaining the functions of paddy fields (http://www.nobi.or.jp/tanbo). /). Thus, the introduction of plantation pattern assessment has the potential to significantly increase forest value.

  As shown in the figure, investors include general investors such as individuals and corporations, companies that wish to purchase CO2 emission credits, tourism companies and sponsor companies that are interested in forest development, and the like. In addition, when participating in a forest reconstruction project using this system, by procuring investment funds in a “lease method”, not only investors with financial strength but also individuals and small businesses with relatively poor resources are able to participate in the reconstruction project. It is possible to participate in Also, by taking a leasing method, it will be involved in reconstruction projects for multiple years, and it will be possible to contribute to corporate CSR activities for a long time. Then, these investors themselves can also send proposals of afforestation patterns that produce commercial value to the forest reconstruction support system 100 via the Internet. Of course, although not directly participating in the investment, other individuals and companies can solicit proposals for afforestation patterns. An investor may be an individual, a company, or an organization, but it can also invest from a single seedling.

  In the proposal of the afforestation pattern collected in this way, the afforestation pattern value evaluation unit 111 asks investors and forestry professionals to vote for the target forest, and according to the result of the vote, a predetermined rule is obtained. Based on the evaluation value. Proposals with high evaluation values will be formally included in the forest reconstruction management plan after considering feasibility, and investment from investors will be widely recruited. The evaluation process itself may be disclosed. In this way, it is possible to create a forest restoration and development plan that can be widely participated by citizens, as well as a plan for the government and some businesses. The evaluation index may be replaced not only with “forest value” but also with “forest restoration project value”. At that time, it is also effective to add “contribution to CSR activities” to the element of business evaluation.

  FIG. 2 is a diagram showing functional blocks of a forest reconstruction support system 100 (hereinafter simply referred to as “this system”) according to an embodiment of the present invention. The configuration and functions of this system will be described in detail with reference to this figure.

  As described above, this system includes the forest value evaluation means 110 as the core part. However, the forest reconstruction development plan input means 101, the afforestation section map database 102 (in the figure, the database is abbreviated as DB), the forest reconstruction promotion The plan presenting means 103, the afforestation pattern proposal accepting means 104, the forest maintenance company estimate acquisition part 120, the CO2 emission trading system I / F part 130, the afforestation growth observation part 140, and the investment acceptance part 150 are provided as components. Hereinafter, each structure is demonstrated in order.

  The forest value evaluation means 110 described above further includes an afforestation pattern value evaluation unit 111, a CO2 absorption value evaluation unit 112, a training / maintenance cost evaluation unit 113, a disaster prevention / environmental conservation value evaluation unit 114, and an employment creation value evaluation unit 115. It is configured. Each evaluation unit evaluates afforestation patterns received by a later-described afforestation pattern proposal receiving unit 104 and quantifies the evaluation.

  The afforestation pattern value evaluation unit 111 provides an aesthetic point of view to other investors and specialists such as forestry business and tourism, in order to calculate commercial values such as aesthetic value, tourism value, and advertisement value of forests. It has a means to get the evaluation from a commercial point of view. Specifically, the afforestation pattern plan is posted on a predetermined website generated by the present system, and an evaluation score for the afforestation pattern plan or an investment amount that the user may invest may be received from the investor terminal 200. To do. The evaluation value of the afforestation pattern is calculated according to a predetermined rule such as summing up the scores of the evaluation points, adding expert evaluation, weighting the points, and the like. The predetermined rule itself may be disclosed.

  FIG. 3 conceptually shows a specific example of this afforestation pattern. Pattern A is a pattern for revitalizing disaster prevention and landscapes. For example, the example in the figure shows the afforestation pattern for revitalizing beach forests destroyed by the tsunami. And value the landscape.

  Pattern B is a pattern for restoring mountains and hills that have been devastated like mine ruins, and places importance on the value of tourism and growth as a new tourist destination. For example, the example in the figure shows a planting pattern plan that fills the entire mountain with cherry trees. Needless to say, the aesthetic value and tourism value are emphasized even if the whole mountain is filled.

  Pattern C is a pattern in which land that is relatively close to urban areas, such as abandoned farming land, is planted to form the advertising value of the afforestation pattern. For example, in the example of the figure, a company logo mark is expressed as an afforestation pattern, aiming at PR effect and image improvement of the company. It goes without saying that investors in this afforestation pattern are companies.

  Moreover, the pattern D is a pattern which attaches importance to the aesthetic value of the modeling beauty that the plantation pattern itself has. For example, as shown in the figure, the planting pattern is made into an artistic design such as a painting or illustration, and the painting or illustration is completely enjoyed as the tree grows, or the trees in the parcel You can also entertain the growth of the game and entertain the game sensation like a team battle. In this case, the investor may be involved in the development and development of the compartments that he invested.

  In this way, by having various people give ideas to afforestation patterns, forests can be developed as new tourist spots and places where people gather. In addition, forest investors themselves can enjoy the growth of the forest.

  Returning to FIG. 2, the CO2 absorption value evaluation unit 112 calculates the CO2 absorption amount of the forest, and based on the emission credit market price obtained from the CO2 emission trading system 400 built in the trading market, Determine the sale price. As shown in FIG. 4, the amount of CO2 absorbed by a tree is the difference between the amount of CO2 absorbed by the tree during photosynthesis and the amount of CO2 emitted by the respiration of the plant itself. This is sometimes called carbon fixation. The amount of CO2 absorbed by photosynthesis is maximized when the tree is in the growth period, and the amount of carbon fixation is also maximized.

  Therefore, the calculation of the carbon fixation amount needs to take into consideration the kind of tree, the region, the sunshine conditions, etc. over a long period of time. In addition, it is indispensable to compare the calculated value with the measured value according to the growth of the tree. However, the calculation method of the carbon fixation amount of the tree (calculation method of the CO2 absorption amount of the forest) itself is not the main point of the present invention, and thus, for example, a known technique such as Patent Document 1 is used.

  FIG. 5 is a diagram showing changes in forest value. In this system, as described above, the forest value evaluation means 110 has the following five values: afforestation pattern value, disaster prevention / environmental conservation value, CO2 absorption value (carbon fixed value), and fostering / maintenance costs. Calculate as an evaluation item. FIG. 5 conceptually shows changes in these five evaluation values together with the age of the tree.

  Firstly, if the land is in a wasteland rather than a forest, the initial cost of the development and maintenance costs is high in the initial stage, such as land parcel maintenance, soil replacement, seedling purchase and planting. Is expected to decrease gradually. As already mentioned, the value of carbon fixation increases during the growth period of the tree, but gradually decreases when the tree grows out. The value of disaster prevention / environment will increase with the growth of trees, but after that, it is considered that it will remain within a certain range. If the land is not wasteland and forests are already formed, the fostering / maintenance cost and disaster prevention / environmental conservation value are almost constant, but the fixed carbon value will gradually decrease. Therefore, in order to increase profits with these three value judgments alone, it is necessary to cut the forest and sell it as timber.

  On the other hand, the value of afforestation pattern is less likely to decline even if tree growth stops, and conversely, depending on the idea of afforestation pattern, the value can be improved. Also, there is a psychological effect that you can enjoy the growth of the tree itself even if it does not reach a plantation pattern that can generate profit until the tree grows to some extent. In addition, the value of the afforestation pattern does not have to be a vast land, and even a land with a relatively small area and a low value for disaster prevention / environmental conservation and CO2 absorption can be well profitable. . Furthermore, even when growth has stopped, changing the planting pattern by replanting may create new value. The forest value evaluation means 110 of this system comprehensively determines the value of such forest over a long period of time, and calculates and predicts the value. This makes it possible to utilize forests as a revenue source with commercial value different from that of conventional forestry.

  Returning to FIG. 2, the breeding / maintenance cost evaluation unit 113 obtains estimated data for forest creation / maintenance cost from the forest area, the tree species, the number of trees, and the afforestation pattern from the forest maintenance company or the forest maintenance company transaction system 300 described later. get. The estimated data acquired here may also be disclosed. Here, the forest maintenance company transaction system 300 is assumed to be a system that is connected to the system through a network and can return an estimation result online in response to an estimate request. However, some manual operations may be included. Good.

  The disaster prevention / environmental conservation value evaluation unit 114 obtains an evaluation of the disaster prevention value of the forest and an evaluation from the viewpoint of the surrounding environment from an external expert, etc., and stores the numerical value according to a predetermined rule. The reason for entrusting the evaluation to outside experts is that it is difficult for general investors to judge the environmental conservation value such as disaster prevention value and water source conservation. Of course, this numerical rule itself is also disclosed.

  The employment creation value evaluation unit 115 extracts the employment creation effect in the region from the estimated data from the training / maintenance cost evaluation unit 113. For this reason, the estimated number of job creations (total number of people) newly born in the region by the forest maintenance business (forestation, training, maintenance business) should be included in the estimated data from the forest maintenance business. Is desirable. In this way, the job creation value of the forest can be calculated by multiplying the total number of jobs created by a predetermined coefficient. Therefore, even if the estimated amount of the forest maintenance business is the same, there will be a difference in job creation value depending on whether the forest maintenance business is a company in the region or a company outside the region. Since the employment creation value evaluation unit 115 acquires data from the training / maintenance cost evaluation unit 113, the employment creation value evaluation unit 115 may be considered as a part of the training / maintenance cost evaluation unit 113.

  In addition, the description shifts to the configuration surrounding the forest value evaluation means 110 in the present system. First, the forest reconstruction training plan input means 101 stores the forest reconstruction training plan 40 created by the forest reconstruction training enterprise 10 in the afforestation section map database 102. Specifically, the afforestation section map DB 102 includes, for each section obtained by dividing the entire target forest and the target forest into predetermined areas, the location, topography, area, soil, tree species that can be grown, sunshine duration, water source, etc. It is a means for storing forest reconstruction plan data that stores various data.

  The forest revitalization plan presentation means 103 visually displays the forest revitalization plan data stored in the plantation section map database 102 on the terminal of the investor so as to be understood by general investors, and solicits proposals for planting patterns Provide a means. The forest reconstruction training plan data is disclosed based on the information stored in the plantation section map database 102 (forest reconstruction training plan storage means). Specifically, for example, the system generates a predetermined presentation screen for each forest based on information stored in the afforestation section map database 102 so as to receive an evaluation from an investor.

  The afforestation pattern proposal accepting means 104 is a means for accepting a proposal for afforestation pattern of the entire target forest or a certain section posted from the investor terminal 200. Specifically, for example, a proposal for afforestation pattern with a drawing is transmitted from a predetermined screen prepared by the system. Needless to say, the forest rehabilitation and development business unit 10 itself may create a reforestation pattern proposal as a draft.

  The forest maintenance company estimate acquisition unit 120 acquires from the forest maintenance company transaction system 300 an estimate of the cost of afforestation, cultivation, and maintenance for each afforestation pattern. Conventionally, such estimates have been made each time by the hands of a contractor, but in this system, it is necessary to continuously obtain a large number of afforestation pattern estimates. It is desirable to construct a quotation system that can format the request form for quotations and send the estimation result (estimated amount) online.

  The CO2 emission trading system I / F unit 130 includes an I / F (interface) with an external CO2 emission trading system 400, and the carbon calculated by the CO2 absorption value evaluation unit 112 from the CO2 emissions trading system 400. Based on the fixed amount (CO2 absorption amount), the economic value of the carbon fixed amount is calculated from the emission credit market price and fed back to the CO2 absorption amount value evaluation unit 112.

  The afforestation growth observation unit 140 acquires basic data for each afforestation section from the forest observation means 500 that scientifically observes the state of the forest. The forest observation means 500 may be, for example, various methods such as satellite photographs, aerial photographs, laser data, and field surveys of the forest in the target area, or a combination thereof, as described in Japanese Patent Application Laid-Open No. 2012-58772. However, it is desirable to be connected to this system by a wireless communication means or the like. The afforestation growth monitoring unit 140 also absorbs CO2 based on forest basic data (tree species, tree height, tree breast height diameter, forest age, area) generated from various types of forest observation information obtained from the forest observation means 500. Is calculated. By doing in this way, it is possible to apply feedback from data based on actual measurement to the CO2 absorption amount predicted by the CO2 absorption amount value evaluation unit 112 when the forest is evaluated. The various data acquired by the afforestation growth monitoring unit 140 can also be displayed on the investor's terminal, and the investor can visually view the state of the forest.

  The investment reception unit 150 presents the forest evaluation value calculated by the forest value evaluation means 110 to the investor, and provides a function for soliciting investment through this system for general users. Specifically, an investment is accepted from an application screen provided by the present system, and a user ID as an investor is assigned when a remittance is received. Needless to say, the profits from the forest are returned to investors.

  By configuring the system in this way, it is possible to provide support for a business entity that performs restoration and cultivation of forests and to realize the object of the present invention to allow more people to participate.

  The functional configuration of the system described above is merely an example, and one functional block (database and function processing unit) may be further divided, or a plurality of functional blocks may be configured as one functional block. . In each function processing unit, a CPU (Central Processing Unit) built in the device or the computer system reads a computer program stored in a storage device such as a ROM (Read Only Memory) or a hard disk, and is executed by the CPU. Realized by a computer program. That is, in each function processing unit, this computer program reads and writes necessary data such as a table from a database (DB; Data Base) stored in a storage device or a storage area on a memory, and may be related in some cases. This is realized by controlling hardware (for example, an input / output device, a display device, and a communication interface device). Further, the database (DB) in the embodiment of the present invention may be a commercial database, but it simply means a collection of tables and files, and the internal structure of the database itself is not questioned.

<Flow of forest value evaluation method>

  FIG. 6 is a diagram summarizing the processing flow of the forest value evaluation method. In the following processing flowchart, the processing order of each step may be changed.

  First, in step S10, the forest value evaluation means 110 calculates the carbon absorption amount from the forest area, tree species, area, and number of trees, and calculates the economic value in the CO2 emission trading market. Specifically, known calculation methods such as those described in Patent Documents 1 and 2 may be used, but more simply, using the trunk material yield table and the yield table curve shown in FIG. It may be calculated roughly. However, BEF (Biomass Expansion Factor) in the figure is the ratio of aboveground biomass (trunk / branch / leaf) to stem biomass, and R (belowground to aboveground biomass ratio) is the underground biomass ( The ratio (root), D (basic wood density), is volume density (ton / m 3), and enlargement factor = BEF × (1 + R). From these parameter values, the amount of forest absorption is calculated by the following formula.

  Absorption (carbon ton / year) = trunk volume increase rate (m3 / year) x volume density (ton / m3) x expansion factor x carbon content

  Of course, since the volume of the trunk (also called the trunk volume) cannot be directly examined before the forest is cultivated, a “harvest table” that can examine the average trunk volume from the tree type and age is used. Calculate (see the upper part of FIG. 7). The graph in the lower part of the figure shows the change of the cedar harvest table with respect to the age class of the trees. The CO2 absorption amount evaluation value is determined based on the absorption amount calculated as described above.

  Next, the forest value evaluation means 110 quantifies the disaster prevention / environmental conservation value based on the expert's evaluation in step S11. Specifically, for example, if an expert's evaluation is obtained in 10 stages, an evaluation value is obtained by multiplying the evaluation value by a predetermined coefficient. The predetermined coefficient is determined in accordance with the purpose of the forest reconstruction and development targeted by the forest reconstruction and development enterprise 10.

  In step S12, the forest value evaluation unit 110 calculates the tourist value and aesthetic value of the forest based on the vote of the investor. Specifically, for example, investor evaluation values for afforestation pattern plans are collected, evaluation values are obtained from experts, a certain weight is applied, and a predetermined coefficient is added to the sum of the evaluation values of investors and experts. To evaluate the afforestation pattern. The predetermined coefficient is determined in accordance with the purpose of the forest reconstruction and development targeted by the forest reconstruction and development enterprise 10. The evaluation value of the investor may be the amount of money for which the investment is offered.

  Further, in step S13, the forest value evaluation unit 110 calculates the breeding / maintenance cost from the estimated price of the forest maintenance company. Specifically, the evaluation value is calculated based on the minimum price or the median price of the estimated price acquired from the forest maintenance business transaction system 300.

  Subsequently, in step S14, the forest value evaluation unit 110 extracts the number of jobs created from the estimated data of the forest maintenance company and calculates an evaluation value. Specifically, the evaluation value is calculated by multiplying the estimate of the number of jobs created in the area acquired from the forest maintenance business transaction system 300 by a predetermined coefficient. Of course, when the estimated data does not include the number of jobs created, the evaluation value is zero.

  In step S15, the forest value evaluation unit 110 calculates the total value of the forest as shown in the evaluation table of FIG. 8 from the above evaluation values. However, in this evaluation table, the breeding / maintenance cost is expressed as a negative value. That is, the higher the cost, the lower the total value. The overall evaluation value may be simply the sum of the above evaluation values, but based on this evaluation table, a judgment meeting, etc. is held inside the forest reconstruction and development business entity 10 and the result is finalized. It is good as the total value of the forest. Note that the total value of forests is not determined solely by land area or number of trees. Of course, it goes without saying that such a forest value comprehensive evaluation table is also made public.

  Finally, in step S16, the forest value evaluation unit 110 calculates the investment amount per forest section based on the total forest value calculated in the above step. Of course, the final investment amount is determined based on the judgment of the forest reconstruction and development enterprise 10 based on the investment amount calculated from the estimation result of the cultivation / maintenance cost and the total value. If it is possible to receive subsidies from the national or local government, the investment amount shall be the total cost minus the amount of subsidies.

<Effect of embodiment>
As described above, according to the embodiment of the present invention, the following effects are produced. First of all, it can provide support for business entities that are engaged in forest restoration and development, and can provide a system that allows more people to participate. Second, the evaluation of forest value includes disaster prevention / environmental conservation value, CO2 absorption value, afforestation pattern value, employment creation value, and development and maintenance costs. In addition, commercial elements such as forest aesthetic value, tourism value, advertising value, regional revitalization, etc. can be added, making it possible to receive a wide range of investment in forest reconstruction. In particular, by adding an evaluation of afforestation patterns, even after tree growth has stopped, the value of forests can be increased depending on the idea of afforestation patterns. Recruitment of proposals for afforestation patterns from investors greatly expands the possibility of acquiring high-value ideas. Third, by systematizing the evaluation process itself, it is possible to obtain and publish the estimation results of forest operators online, and to disclose the evaluation method itself to general investors.
