Description

  The present invention relates to an apparatus for searching for farmland.

  In Japan, due to the provisions of the Agricultural Land Law, farmland cannot be diverted to uses other than farmland without permission. Therefore, for example, when a parent who farms in the suburbs died and a child living in the parent's farmland is inherited, due to problems such as travel time, the child cannot inherit the farming, and the farmland is left as it is. In many cases, they are left unattended. Such a case is one of the factors leading to the generation of abandoned farmland. For example, according to the 2008 survey, the nation's abandoned cultivated land is about 230,000 hectares, accounting for about 5% of all Japanese agricultural land.

  In addition, although the area of farmland managed by bearers such as certified farmers has been increasing year by year, the use of farmland for bearers has not been accumulated. One of the reasons is, for example, that the accumulated farmland is dispersed. If farmland is dispersed, production costs cannot be reduced due to increased travel time and efficient use of machines, and the benefits of scale expansion cannot be fully utilized.

  Compared with the United States, China, etc., Japan has a small farmland area and the above-mentioned problems, so Japanese farmers have a high production cost and management has deteriorated. In addition, Japan's food self-sufficiency rate cannot be increased, and imports from overseas have to be relied upon.

  In view of the above circumstances, the present invention provides a farmland search apparatus, a farmland search program, and a farmland search method capable of searching for farmland candidates effective for realizing expansion of farmland, prevention of generation of abandoned farmland, and prevention of dispersion of farmland. The purpose is to provide.

  According to one aspect of the apparatus, a farmland search device including an input unit, a storage unit, a specifying unit, a determination unit, and a display unit is provided. Here, the input unit accepts an input of a field number of a field or a rice field as a search target area number. The storage unit stores registration information, map information, and information on a minimum area where setting of a lease right for a land having a field or a field is permitted in the region. Based on the map information that identifies the stroke number of each location number stored in the storage unit, the identification unit determines all lot numbers adjacent to the search target lot number and / or all lot numbers in the same area as the search target lot number Specify as lot number. The determination unit is identified by the identification unit based on the registration information stored in the storage unit, the map information, and information on the minimum area in which the setting of the lease right for the land or field of each region is permitted. It is determined whether the determined determination target lot number is a lot number that is highly likely to be abandoned cultivation and / or a lot number that the owner is likely to lend. The display unit displays the determination target lot number determined by the determination unit as a lot number that is highly likely to be an abandoned cultivation area and / or a lot number that the owner is likely to lend.

  According to one aspect of the program, an agricultural land search program for an agricultural land search device is provided. This program causes a computer to execute the following processing. The input of the lot number of the field or the rice field as the search target lot number is accepted via the input unit. Based on the map information that identifies the strokes of each number stored in the storage unit, all the lot numbers adjacent to the search target lot number and / or all the lot numbers in the same area as the search target lot number are specified as the determination target lot numbers. . Based on the registration information stored in the storage unit, the map information, and the information on the minimum area where the setting of the lease right for the land of the field or field is permitted in each region, It is determined whether the lot number is likely to be an abandoned cultivation land and / or the lot number is likely to be lent by the owner. A lot number that is likely to be abandoned cultivation and / or a lot number that is judged as a lot number that is likely to be lent by the owner is displayed on the display unit.

  According to one aspect of the method, a farmland search method performed by a farmland search apparatus is provided. In this method, the computer does the following: The input of the lot number of the field or the rice field as the search target lot number is accepted via the input unit. Based on the map information that identifies the strokes of each number stored in the storage unit, all the lot numbers adjacent to the search target lot number and / or all the lot numbers in the same area as the search target lot number are specified as the determination target lot numbers. . Based on the registration information stored in the storage unit, the map information, and the information on the minimum area where the setting of the lease right for the land of the field or field is permitted in each region, It is determined whether the lot number is likely to be an abandoned cultivation land and / or the lot number is likely to be lent by the owner. A lot number that is likely to be abandoned cultivation and / or a lot number that is judged as a lot number that is likely to be lent by the owner is displayed on the display unit.

As shown in FIG. 8, the lease condition table 180 stores information such as the minimum lease permitted area for each region. According to the example shown in FIG. 8, for example, it is indicated that the minimum lease permission area of the region “Hokkaido” is “2ha”.

Next, the operation of the farmland search device according to the present embodiment will be described.
FIG. 9 is a flowchart illustrating an example of the operation of the farmland search device according to the present embodiment.
As shown in FIG. 9, in this operation, first, from the searcher, the input unit 110 inputs the name of the searcher, the lot number of the land (the field is a field or a rice field) owned by the searcher, and the search option. (S101).

  The search option is for specifying a search range. In the present embodiment, as a search option, a search option A in which the search range is all the lot numbers adjacent to the input lot number, a search option B in which all the lot numbers in the same district as the input lot number, Any one of the search options C as the combined lot number can be selected. In this operation, it is assumed that search option C is input as a search option.

  In S101, the farmland aggregation determination unit 140 uses the received name and lot number information as the “searcher name” and “search target lot number” information in the farm table 170 to illustrate the farmland expansion / dispersion prevention system 100. Do not store temporarily in working memory. Hereinafter, a working memory (not shown) of the farmland expansion / dispersion prevention system 100 is simply referred to as a working memory. Further, the farmland aggregation determination unit 140 obtains the current date information according to the accepted search option C, and displays the “farmland candidate search date (adjacent)” and “farmland candidate search date (district)” in the farmland table 170. Is temporarily stored in the working memory.

  Next, the brush information acquisition unit 120 acquires information on all lot numbers adjacent to the search target lot number based on information stored in the map graphic brush point table 200, the map graphic connection table 300, and the like (S102). ). Subsequently, the determination target lot number specifying unit 130 specifies all the adjacent lot numbers as determination target lot numbers (S103). As will be described in detail later with reference to FIG. 10, the farmland aggregation determination unit 140 cooperates with the brush information acquisition unit 120 to determine the possibility of farmland expansion for each determination target lot number (S104). In the process of performing this determination, for example, it is determined for each determination target lot number whether or not there is a possibility of becoming an abandoned cultivation land or a possibility of lending by the owner.

  Next, the brush information acquisition unit 120 acquires information on all the lot numbers in the same district as the search target lot number based on the information stored in the registration information DB 500 or the like (S105). Subsequently, the determination target lot number specifying unit 130 specifies the remaining lot numbers obtained by removing the lot numbers adjacent to the search target lot number from all the lot numbers in the same area as the search target lot number (S106). Then, as in S104, as will be described in detail later with reference to FIG. 10, the farmland aggregation determination unit 140 cooperates with the brush information acquisition unit 120 to determine the possibility of farmland expansion for each determination target lot number (S107). ).

  Next, the farmland aggregation determination unit 140 cooperates with the brush information acquisition unit 120 and can borrow a farmland candidate corresponding to the lot number input in S101, that is, an effective farmland for expansion and prevention of decentralization of the farmland. A candidate for a highly farmland is displayed on the display unit 150 (S108). Specifically, the owner is likely to lend in the future on the land that is the search target lot number, the land that is likely to be abandoned cultivation in the land that is the judgment target lot number, and the land that is the judgment target lot number The display unit 150 displays the land and the land determined as the other determination target lot number in a distinguishable manner. Such display processing is performed based on the information stored in the map graphic brush point table 200 and the map graphic connection table 300 and the information stored in the farmland table 170. Here, the information stored in the map graphic brush point table 200 and the map graphic connection table 300 used for the display processing includes the search target lot number and all the lot numbers determined as the determination target lot numbers in S103 and S106. Information about. Further, the information stored in the farmland table 170 used for the display process is information on all the lot numbers determined as the judgment target lot numbers in S103 and S106. The information stored in the map graphic brush point table 200 and the map graphic connection table 300 is referred to by the brush information acquisition unit 120. Information stored in the farmland table 170 is referred to by the farmland aggregation determination unit 140.

FIG. 10 is a diagram illustrating a flowchart according to an example of processing (S104, S107) for determining farmland expansion possibility for each determination target lot number.
As shown in FIG. 10, in this process, first, the determination target lot numbers are defined as the first, second, third,... Nth determination target lot numbers in ascending order (S201).

  Subsequently, as n = 1 (S202), the brush information acquisition unit 120 refers to the registration information DB 500, the brush attribute table 400, and the like, and as the information of the nth determination target lot number, the owner name, owner address, rental Information about the right setting status, area, and location is acquired (S203). In S203, the farmland aggregation determination unit 140 temporarily stores the acquired owner name and owner address information as “owner name” and “owner address” information in the farmer table 160 in the working memory. To store. Also, the nth determination target lot number and the acquired lease right setting status, area, and land information are used as information on the “land number”, “rental right setting date”, “area”, and “ground” in the farmland table 170. Temporarily store in working memory.

  Subsequently, the farmland aggregation determination unit 140 initializes a cultivation abandonment possibility flag, a lending possibility flag, a near future lending possibility flag, and an area condition flag (S204). That is, the value of these flags is set to 0, and the information is used as information on “candidate F”, “loanable F”, “near future loanable F”, and “area condition F” in the farmland table 170 as working memory. Temporarily store.

Subsequently, as will be described later in detail with reference to FIG. 11, the possibility of abandonment of cultivation and the possibility of lending are determined (S205).
Subsequently, as will be described in detail later with reference to FIG. 12, the possibility of lending in the near future is determined (S206).

  Subsequently, the cultivation abandonment possibility flag, the lending possibility flag, and the near future stored in the working memory as information of “cancellation candidate F”, “loanable F”, and “future lending possibility F” of the farmland table 170 Based on the information on the lending possibility flag, the following determination is performed (S207). That is, it is determined whether or not the value of any one of the possibility flag of the cultivation abandonment possibility flag, the lending possibility flag, and the near future lending possibility flag is 1. If the determination result is No, the process proceeds to S211.

On the other hand, if the determination result in S207 is Yes, it is determined whether the area condition is cleared, as will be described in detail with reference to FIG. 13 (S208).
Subsequently, it is determined whether or not the value of the area condition flag is 1 based on the area condition flag information stored in the working memory as the information of “area condition F” in the farmland table 170 (S209). If the determination result is No, the process proceeds to S211.

  On the other hand, when the determination result of S209 is Yes, information on the nth determination target lot number stored in the working memory as information of the farmer table 160 and the farmland table 170 is stored in the farmer table 160 and the farmland table 170. Store (S210). In S210, information stored in the working memory is cleared as information on the farmer table 160 and the farmland table 170. However, the information stored in the working memory as “searcher name”, “farmland candidate search date (adjacent)”, “farmland candidate search date (district)”, and “search target lot number” in the farmer table 160 is Removed (not cleared).

After S210 (or when S207 or S209 is No), n is set to n + 1 (S211), and it is determined whether or not n> N (S212). Here, if the determination result is No, the process returns to S203, and processing for the next determination target lot number is started.
On the other hand, if the determination result in S212 is Yes, this process ends (returns).

FIG. 11 is a flowchart according to an example of processing (S205) for determining the possibility of abandonment of cultivation and the possibility of lending.
As shown in FIG. 11, in this process, first, the brush information acquisition unit 120 refers to the registration information DB 500, and uses the owner name of the nth determination target lot number acquired in S203 as a search key. The date of registration related to the first entry is acquired (S301). In S301, the farmland aggregation determination unit 140 temporarily stores the acquired registration date information as “first registration date” information in the farmer table 160 in the working memory.

  Subsequently, the farmland aggregation determination unit 140 calculates the elapsed date from the registration date acquired in S301 to the present date, and sets the age level of the owner to “high” or according to the elapsed date. It is classified into “low” (S302). For example, if the elapsed date is 30 years or more, it is classified as “high”, and if it is less than 30 years, it is classified as “low”. Such classification is based on the assumption that the age level of the owner will be higher (elderly) as the number of years from the date of registration to the present date of registration is longer. Yes. In S <b> 302, the farmland aggregation determination unit 140 temporarily stores the classified age level information as “age level” information in the farmer table 160 in the working memory.

  Subsequently, the brush information acquisition unit 120 refers to the registration information DB 500, and uses the owner information (name, address, etc.) of the nth determination target lot number acquired in S203 as a search key, and other lot numbers owned by the owner. (However, information about the field is a field or a rice field is acquired (S303). Further, in S303, the farmland aggregation determination unit 140 further determines, based on the information, the land for which the lease right is set in the land of another lot number owned by the owner (note that the field is a field or a rice field). The presence or absence of is determined. Then, the information of the determination result (there is the presence or absence of the land for which the lease right is set) is temporarily stored in the working memory as the information of “the presence / absence of the lease right to the owner” of the farmland table 170. Store.

  Subsequently, the brush information acquisition unit 120 refers to the map graphic brush border table 200, the map graphic connection table 300, and the registration information DB 500, and the coordinates of the land of the nth determination target lot number and the coordinates of the owner's address. Information about is acquired (S304).

  Subsequently, the farmland aggregation determination unit 140 obtains a linear distance between the land of the nth determination target lot number and the land of the owner's address based on the information acquired in S304 (S305). In S <b> 305, the farmland aggregation determination unit 140 temporarily stores the obtained straight distance information in the working memory as “distance to owner address” information in the farmland table 170.

  Subsequently, the farmland aggregation determination unit 140 determines whether or not the linear distance obtained in S305 is 350 m or less (S306). In addition, in such a determination, if the linear distance exceeds 350 m, the land of the nth determination target lot number (however, when the ground is a field or a rice field) becomes an abandoned cultivation area due to problems such as an increase in travel time. This is done with the assumption that the possibility is high and that the owner is likely to lend the land. In this example, the distance that is the determination criterion of S306 is 350 m, but this is an example, and other distances can be set based on the above estimation. The determination in S306 is an example of whether or not the first condition is satisfied.

If the determination result in S306 is No, this flow ends (returns).
On the other hand, if the determination result is Yes, the farmland aggregation determination unit 140 extracts the information of the nth determination target lot number stored in the working memory as the “ground” information of the farmland table 170 in S203 (S307). ), It is determined whether or not the field is a field or a rice field (S308). Note that the determination in S308 is an example of whether or not the second condition is satisfied.

If the determination result in S308 is No, this flow ends (returns).
On the other hand, if the determination result is Yes, the farmland aggregation determination unit 140 extracts information on the setting status of the lease right stored in the working memory as information on the “rental right setting date” in the farmland table 170 in S203. (S309). Then, from the information, it is determined whether or not the lease right is set for the land of the nth determination target lot number (S310). Note that the determination in S310 is an example of whether or not the third condition is satisfied.

If the determination result in S310 is No, this flow ends (returns).
On the other hand, when the determination result is Yes, the farmland aggregation determination unit 140 sets the value of the farming abandonment possibility flag to 1 and stores the information in the working memory as information of the “cancellation candidate F” in the farmland table 170. Store temporarily (S311). Note that the value of the cultivation abandonment possibility flag being 1 indicates, for example, that the land of the nth determination target lot number is highly likely to be an abandonment cultivation area.

  Subsequently, the farmland aggregation determination unit 140 uses the information stored in the working memory as the information “presence / absence of lease to other owners” of the farmland table 170 in S303. If the information is present, the following determination is made (S312). That is, it is determined whether or not the lease right has been set within the past year in the land of another lot number owned by the owner of the land of the nth determination target lot number. This determination is made, for example, by the brush information acquisition unit 120 from the registration information DB 500 regarding the lot number for which the lease right is set in another lot number owned by the owner (information such as the set date of the lease right). ) And the farmland aggregation determination unit 140 performs based on the information. In addition, such a determination is made for the land of the nth determination target lot number if the lease right is set within the past year in the land of another lot number owned by the owner of the land of the nth determination target lot number. This is done on the assumption that the owner is more likely to lend. In this example, the period that is the determination criterion of S312 is set to be within the past year, but this is an example, and other periods can be set based on the above estimation. The determination in S312 is an example of whether or not the fourth condition is satisfied.

If the determination result in S312 is No, this flow ends (returns).
On the other hand, when the determination result is Yes, the farmland aggregation determination unit 140 sets the value of the lending possibility flag to 1 and temporarily stores the information in the working memory as the “loanable F” information in the farmland table 170. (S313), and this flow ends (returns). Note that the value of the lending possibility flag being 1 indicates, for example, that the owner is likely to lend the land of the nth determination target lot number.

FIG. 12 is a flowchart according to an example of a process (S206) for determining the possibility of lending in the near future.
As shown in FIG. 12, in this process, first, the processes of S401 to S403 are performed. In this processing, the same processing as S306 to S308 is performed.

  Subsequently, the farmland aggregation determination unit 140 extracts information on the age level stored in the working memory as information on the “age level” in the farmer table 160 in S302, and determines whether the age level is “high”. Determine (S404). Note that, in such a determination, when the age level is “high”, the owner is estimated to be old, so the possibility that the owner lends the land of the nth determination target lot number is high. It is done on the assumption that it will be. The determination in S404 is an example of whether or not the fifth condition is satisfied.

If the determination result in S404 is No, this flow ends (returns).
On the other hand, when the determination result is Yes, the farmland aggregation determination unit 140 sets the value of the near-future lending possibility flag to 1, and uses the information as information on “Near-future lending available F” in the farmland table 170. The data is temporarily stored in the working memory (S405), and this flow ends (returns). Note that the value of the near future lending possibility flag indicates that the owner is likely to lend the land of the nth determination target lot number in the near future.

FIG. 13 is a flowchart according to an example of processing (S208) for determining whether the area condition is cleared.
As shown in FIG. 13, in this process, first, the farmland aggregation determination unit 140 acquires the minimum rent permitted area corresponding to the area to which the search target lot number belongs from the rent condition table 180 (S501). The search target lot number is obtained by extracting the lot number information stored in the working memory as the “search target lot number” information in the farmer table 160 in S101.

  Subsequently, the brush information acquisition unit 120 refers to the registration information DB 500 and uses the information (name) of the owner (searcher) of the search target lot as a search key for other lot numbers owned by the owner of the search target lot. Information (area and area) is acquired (S502). Note that the information (name) of the owner of the search target lot number is obtained by extracting the name information stored in the working memory as the “searcher name” information in the farmer table 160 in S101.

  Subsequently, the farmland aggregation determination unit 140, based on the information acquired in S502, in the other lot numbers owned by the owner of the search target lot number, the land whose field number is the field number of the field or the rice field, and the nth determination target lot number The total area with other land is obtained (S503). In S <b> 503, the farmland aggregation determination unit 140 temporarily stores the total area information as “area” information in the farmland table 170 in the working memory.

  Subsequently, the farmland aggregation determination unit 140 determines whether or not the total area obtained in S503 exceeds the minimum rent permitted area acquired in S501 (S504). Note that the determination in S504 is an example of whether or not the sixth condition is satisfied.

If the determination result in S504 is No, this flow ends (returns).
On the other hand, if the determination result in S504 is Yes, the farmland aggregation determination unit 140 sets the value of the area condition flag to 1 and temporarily stores the information in the working memory as information on the “area condition F” in the farmland table 170. (S505) and this flow ends (returns). Note that the area condition flag value of 1 indicates that, for example, when the searcher borrows the land of the nth determination target lot number, the condition of the minimum area that permits the setting of the lease right is satisfied. ing.

  Thereafter, when the process proceeds to S210 in the process of S104, in S210, the information stored in the farmer table area of the working memory is stored in the farmer table 160 and stored in the farmland table area of the working memory. Information is stored in the farmland table 170.

FIG. 24 is a diagram schematically illustrating an example of information stored in the farmer table 160 and the farmland table 170 when the processing of S107 is completed.
In the example shown in FIG. 24, information about three determination target lot numbers is stored in the farmer table 160 and the farm land table 170. However, for the information stored in the farmer table 160, only the information about the judgment target lot number “24” is shown, and the information about the other two judgment target lot numbers “15” and “28” is omitted. ing.

FIG. 25 is a diagram illustrating a display example displayed on the display unit 150 by the process of S108.
Note that this display example is a display example based on information stored in the farmer table 160 and the farmland table 170 shown in FIG.

  As shown in FIG. 25, in this display example, there is a possibility that the land that is likely to be abandoned cultivation in the land that is the search target lot number and the land that is the determination target lot number, and the owner may lend in the future. It shows that high land and other land are displayed in a distinguishable manner. Here, the land of the search target lot number is the land of the lot number “18”. Of the lands determined as the determination target lot numbers, the lands with a high possibility of becoming abandoned cultivation are the lands with lot numbers “15” and “28”. Of the lands determined as the determination target lot numbers, the land that is likely to be rented by the owner in the future is the land with the lot number “24”. Among the lands determined as the determination target lot numbers, the other lands are the lot numbers “17”, “21”, “29”, and “60”.

  In this example, in the information stored in the farmland table 170 (see the farmland table 170 in FIG. 24), the “lot number” in which “Near-future lending available F” is “1” (“●”) is “ The land of “24” is the land of the determination target lot number that the owner is likely to lend in the future. In addition, the other “land numbers” of “15” and “28” are the land of the judgment target land numbers that are highly likely to be abandoned cultivation land.

  In addition, in this example, the land of the lot number to be searched, the land of the lot number that is likely to become an abandoned cultivation area, and the land of the lot number that the owner is likely to lend in the future, together with corresponding icons, respectively. By displaying, including other lands, those lands are displayed in a distinguishable manner. However, the method of displaying the land so as to be distinguishable is not limited to this, and other methods such as color coding may be employed.

  In addition, in this example, if a land with a lot number that is likely to become an abandoned farming land or a land number that is likely to be rented in the future by the owner is adjacent to the land with the lot number to be searched, the corresponding icon is enlarged. To be displayed. The reason for this is that when the searcher borrows the land, it is particularly effective for preventing the expansion and decentralization of the farmland and also preventing the generation of abandoned farmland. In the example shown in FIG. 25, since the land with the lot number “24” that the owner is likely to lend in the future is adjacent to the land with the search target lot number “18”, the land with the lot number “24” corresponds to the land. The icon is displayed larger.

  According to the display example shown in FIG. 25, the searcher selects the farm numbers with the lot numbers “15”, “24”, “ It can be determined that the land is 28 ". Among them, it is possible to determine that a particularly effective farmland is the farmland having the lot number “24”.

  As described above, according to the farmland search device according to the present embodiment, a searcher (for example, a farmer who wants to expand farmland) can input and expand the farmland by inputting the lot number of the farmland that he / she owns. It is possible to search for farmland with a high possibility of borrowing that is effective for prevention and prevention of abandoned cultivation.

  In the description of the operation of the farmland search apparatus according to the present embodiment, an example in which the search option C is input as the search option in S101 of FIG. 9 has been described. However, the search option A and the search option B are input. In such a case, the following operation is performed. That is, when the search option A is input, since the search range is set to all the lot numbers adjacent to the search target lot number, the search range is set to all the lot numbers in the same district as the search target lot number. The processing of S105 to S107 is not performed. On the other hand, when the search option B is input, the search range is set to all the lot numbers in the same district as the search target lot number. The processing of S102 to S104 is not performed.
