## Abstract

This study explored the rural revitalizing strategy in FAO's Globally Important Agricultural Heritage System (GIAHS) site in Noto Peninsula, Ishikawa Prefecture of Japan, using a case study of edible wild plants. This study assessed the current and possible future utilization of edible wild plants as one important NTFP by clarifying the attitudes of consumers and exploring the challenges of harvesting edible wild plants. Traditional ecological knowledge associated with edible wild plants and the related attitudes of consumers towards wild plants was documented. A questionnaire survey found that a majority of the respondents held positive attitude towards edible wild plants as being healthy, safe food, part of traditional dietary culture. Increasing demand of edible wild plants from urban residents aroused conflicts with local residents’ interest given that around 86% of the forested hills are private in Noto Region. Non timber forest products (NTFP) extraction can be seen as a tool for creating socioeconomic relationships that are dependent on healthy, biodiverse ecosystems. It was suggested that Japanese Agricultural Cooperatives (JA) and Forestry Cooperatives (FCA) could be involved with GIAHS process. As important traditional dietary and ecological system, edible wild plants should be a part of GIAHS project for rural revitalization.

## Body

## 1. Introduction

As a hilly and mountainous country, throughout history the people of Japan have developed integrated management knowledge related to forested mountains, in particular, those low hills adjacent to human settlements.Satoyama in Japan has been shaped to a great extent by centuries of management of coppice woodlands on hillside landscapes [1]. A satoyama landscape is an agricultural land use system comprised of secondary forest, farmlands, settlements, and reservoirs [1]. The ecosystems of the secondary woodlands have provided critical services, which benefit human well-being, as well as rich biodiversity [2]. People have lived on the wild plants harvested from the hills and developed rich knowledge related to the uses of wild plants [3]. Some species of wild edible plants, mushrooms, and seaweeds are crucial in various fields of life (e.g., traditional diet system).Coppice woodlands are managed for the production of wood or charcoal and are cut regularly for this purpose. With the depopulation, migration, and change of life styles after the rapid urbanization in the 1960s, similar to the other parts in the world, however, the forested mountain and traditional knowledge related to it have been degrading [1]. Conversion to coniferous tree plantation to produce timbers has also dramatically changed coppice forest. As a result, the undermanaged forests have threatened the diversity of biology and cultures [4, 5]. Since the 1980s, the national initiatives have been launched to conserve satoyama landscapes, local and regional initiatives have also increased.Environmental conservation insatoyama has been the focus of academic and policy-making efforts in Japan recently. Substantial research papers report the concerns of environmental conservation both in Japanese and English [6, 7]. Since the 1980s, laws were stipulated to regulate satoyama landscape mainly by setting limitation to residential and commercial land development. Recent laws relevant to satoyama have been implemented in Japan, including the Act on the Promotion of Nature Restoration (2002), Landscapes Act (2004), and Act on Promotion of Ecotourism (2007) [2].How to conserve the biodiversity insatoyama and revitalize the rural areas has been one of key issues for policy makers at all levels from national government to municipalities. Ecological functions in spite of coppice or timber production become considered as the major purposes of satoyama. In comparison to the substantial efforts of environmental conservation in Japan, uses of natural resources, in particular, non timber forest products (NTFPs) were much less discussed.The Noto Region in Ishikawa Prefecture (Figure1), as a microcosm of satoyama, has been designated as a Globally Important Agricultural Heritage Systems (GIAHS) site in June, 2011. GIAHS was defined as “Remarkable land use systems and landscapes which are rich in globally significant biological diversity evolving from the co-adaptation of a community with its environment and its needs and aspirations for sustainable development.” [11] As a GIAHS site, it is urgent and vital to develop strategies for dynamic conservation and adaptive management of local agricultural biodiversity, knowledge systems, food and livelihood security, and cultures.Figure 1
Location of Noto PeninsulaHumans have inhabited the Noto Region for more than one thousand years by utilizing the natural resources both from the hills and the sea.Satoyama in the Noto Region in Japan has abundant species of wild plants which people have utilized for more than one thousand years.Since 2008, output value from non timber forest product has grown to account for more than half of the gross output from forests in Japan [12]. In contrast to its increasing importance in forestry, studies relevant to wild edible plants are still sporadic. Some early researches mentioned the liking [13] and utilization of edible wild plants [14, 15]. There exists a rising demand of edible wild plants; however, big stores in metropolis were reluctant to sell wild plants due to its small amount of potential customers [16]. Consumers’ attitude towards edible wild plants is still little known. Ishikawa Prefecture can serve as an appropriate survey site for possessing rich plant species and being the center of Hokuriku Area in Japan.It is expected that results of this study will contribute to the strategies of revitalizing the managed secondary forest ecosystem by promoting recreational use of forest resources. The primary goal of this study is to explore the potential use of natural resources in a sustainable way in the managed secondary forests, which have greatly degraded without thinning in Japan. This study was designed to assess the current and possible future utilization of edible wild plants as one important NTFP by clarifying the attitudes of consumers and exploring the challenges of harvesting edible wild plants. In this study, the effect of demographic characteristic of consumers towards wild plant consumption was also discussed.Sansai is commonly used in Japanese, here it was used to be equivalent to edible wild plants. Sansai also includes various mushrooms besides edible wild plants; however, edible mushrooms are only harvested in autumn, and it needs much related knowledge to tell mushrooms from edible or poisonous. Thus, we only limit sansai to edible wild plants in this study.Some of the objectives of the study are the documentation of traditional ecological knowledge associated with edible wild plants and the related attitudes of consumers towards wild plants. Specially, the objectives of this study include the following.(1)
Document the species of edible wild plants and the traditional uses of the wild plants, their uses as food or medicine, and their habitat.(2)
Record the traditional knowledge associated with harvest to ensure no harm to natural regeneration.(3)
Survey the attitudes of consumers, including local people, towards edible wild plants. Compare the attitude of residents in remote mountainous areas and urban areas. How demographic characteristics (gender, age, and education) of consumers affect their frequency of purchasing, eating, or harvesting edible wild plants.(4)
Discuss the challenges to the harvest and consumption of edible wild plant. The conflicts of interest of these stakeholders will be discussed and the potential policy implication is also tentatively brought forward.


## 2. Survey Sites and Method

The hilly Noto Peninsula, also usually called the Noto region, is located in the north of Ishikawa Prefecture, which juts out into the Sea of Japan. As a narrow long peninsula extending from the south to the north, the area is characterized by a configuration of closely knit togethersatoyama and satoumilandscapes, with their associated land uses, diversified livelihoods based on agriculture, forestry and fisheries, lifestyles and customs, and biodiversity. The earliest archaeological evidence of rice cultivation in the region dates back to the mid-Yayoi period (300BC–250AD).Two survey sites were selected to interview the respondents, Oozora Farmers’ Market and Uchinada Farmers’ Market. The former is located in the town of Anamizu in the centre of Noto Peninsula, nearby the entrance to express way. The latter is located in Kanazawa City, the capital city of Ishikawa Prefecture and also the central city in the Hokuriku Region in Japan. These two sites were selected to represent the market in the production place of edible wild plants among the hilly areas and the other one in the urban area as the market center in Ishikawa Prefecture, respectively. These stores are managed as retail store of Agriculture Association Group. They help to sell farmers’ product and charge a commission of around 15% of the total sales.A combination of qualitative and quantitative data collection methods was used depending on study purposes in this study. The questionnaire survey was conducted in May, 2011, when many species of wild edible plants were collected and sold in the market. During a long vocation at the beginning of May, usually called the Golden Week, warm days in spring have attracted people, not only local residents, but also those from nearby cities to travel. Farmers’ market is among one of best popular sites for visitors. Visitors in this season can represent a wide variety besides local residents.In depth interviews were conducted with multistakeholders relevant to the utilization of wild edible plants: collectors, consumers, and specialists of wild edible plants, forest owners, Forest Cooperation Association in Noto, and municipalities. Interviews lasted around an hour at average. We communicated in Japanese and notes were also taken in Japanese. Then interviews were translated into English. Consumers were briefly interviewed after a questionnaire sheet completed when time allowed to grasp additional consumers’ attitudes toward wild edible plants.A list of edible wild plants was compiled after consulting with local experts of vegetation. First, we obtained a list of edible wild plants from the Ishikawa Prefecture office. The list was revised and extensively recompiled by deleting extinct species and wrong data and adding missing data. In order to identify plant species and habitat and obtain relevant ecological knowledge, we have visited the forest to pick up edible wild plants with Ms. Fujiko Taniguchi, who is a registered edible plant cooking adviser with vegetation identification experience of around 50 yrs., to collect edible plants during the three months of April–June, 2011. We also have spent several months to collect basic ecological knowledge by learning cooking and preservation skills of edible wild plants. Ecological knowledge of plant habitats and different ways of use were documented in detail.A questionnaire survey was designed to clarify the species and frequency of wild edible plants have been widely collected, purchased or eaten. The respondents were split into three groups according to their residence, residents in Noto Region (also refer to group I in this paper), in Ishikawa Prefecture except Noto Region (group II), and outside Ishikawa Prefecture (group III).The questionnaire survey is comprised of four different sections. The first section contained the personal profile of the respondents, including questions related to ages, education, and their residence. The second section includes the frequency and items of edible plants that they harvest, purchase, or eat. The third section includes questions of their attitudes toward edible wild plants. Respondents were asked to comment on their perceived factors of being delicious, healthy, cheap at price, easy to buy, safe food without the use of pesticides, environmental friendly without the input of chemical fertilizers. A five-point Likert scale ranging from “strongly agree (=5), agree (=4), no idea (=3), disagree (=2), highly disagree (=1)” was used to get the respondent’s opinion on edible wild plants. In the last section of the open question, the respondent was asked to freely write down their opinions related to harvest, purchase, and cooking of edible wild plants.A total number of 208 copies of questionnaires were collected and completed without missing values in the two survey sites: 106 copies in Anamizu Farmers’ Market and 102 copies in Uchinada Farmers’ Market. About 43 respondents in Anamizu and 35 in Uchinada refused to answer the questionnaire. Each copy was checked and the respondent was asked to complete if any missing values found. All completed questionnaire sheets collected from the two survey sites were split into three groups by respondents’ residence, Noto Region (group I), Ishikawa Prefecture other than Noto Region (group II), outside Ishikawa Prefecture (group III). In this study, we adopted the definition of Noto Region according to GIAHS site project as four cities and four towns in the Noto Peninsula on the Japan Sea side of Japan’s main island, Honshu: Nanao City, Wajima City, Suzu City, Hakui City, Shika Town, Nakanoto Town, Anamizu Town, and Noto Town. The respondents of group II can be described as urban residents who are majorly from Kanazawa and its neighboring areas to the south of Noto Region. Group III consists of residents from metropolis of Tokyo, Kyoto, and Osaka and other mountainous areas.The descriptive profile of respondents is listed in Table1. Since the number of the results of group III is much less than groups I and II, this study will be discussed based on the comparison between groups I and II, while using group III as reference, moreover, respondents of group III are a mix of rural and urban residents. The results had a good balance of male and female respondents with female respondents being slightly more than male ones. Respondents from group I are a little older than group II, which is consistent with the current population situation with the increasing ageing people in the rural areas.Table 1

Two categories of respondents’ behavior were classified: high frequency referred to those who purchased, harvested, or ate more than once a week; low frequency referred to those who never purchased, harvested, or ate wild edible plants or only a few times a year. Because these two categories were unordered, binary logistic model were used for analysis. SPSS 16.0 was used to estimate the binary logistic model.


## 3. Results and Discussion

### 3.1. Documentation of Use of Edible Wild Plants

The edible wild plants were compiled with the help of a local vegetation specialist named Fujiko Taniguchi and the reference to some flora books [8–10]. The detail of their habitat, uses as food or medicine, and which part of the plant could be used were tallied. We got a result of around 184 species, belonging to 67 families, which can be used as food both/or medicine in Noto Region (Table 2). Among them, around 176 species belonging to 65 families are edible; around 60 species belonging to 36 families can be used as medicine (Table 3). Almost all parts of the plants can be used, including the sprouts, flowers, fruits, seeds, soft stems, and roots.Table 2

### 3.2. Attitude toward Edible Wild Plants

#### 3.2.1. Preferences of Edible Wild Plants

In the second part of the questionnaire sheet, the interviewees were asked how frequently they purchase, eat, and collect edible wild plants during the harvest season of edible wild plants from January to June. The results were listed in Table4. From Table 4, we can see that more than 40% of the respondents from the three groups take sansei more than once a week.Table 4

The respondents of group I from Noto Region use and harvest wild edible plants much more often than group II and group III. A big difference was in the frequency of taking and collecting edible plant. Around 78% of the respondents from Group I take sansai more than once a week, comparing to only 42% of respondents from Group II. Around 48% of respondents from group I collectsansai more than once a week, comparing to only 12.9% of respondents from group II. Around 87% of respondents from group II answered that they have only a few or no experience of sansai harvesting. Respondents from group I buy sansai slightly more often than those from group II.Difference was also found in the results of where to buysansai(Table 6). About 61 respondents from group I answered this question, among which 62.3% usually buy from a famers’ market, and 34.4% usually buy from a supermarket. Among the total 77 respondents from group II, around 28.6% of which usually buy from a farmers’ market, and around two-thirds of them usually buy from a supermarket.Respondents were also asked to select the edible wild plant species of three sources; buying, harvesting, and receiving form their relatives. In this question (multiple choice question), around 12 kinds of wild plants, which are commonly used in Ishikawa Prefecture, were listed:Petasites japonicus, Allium schoenoprasum, Aralia elata, Aralia cordata, Allium victorialisvar.platyphyllum, Matteuccia struthiopteris, Pteridium aquilinumvar.latiusculum, Petasites japonicus, Elatostema umbellatumvar.majus,  Oenanthe javanica, Osmunda japonica, and bamboo shoot sprout. The result of this question is closely correlated to that of the previous question of frequency. The result shows that more than one-fourth of the respondents harvest 7 kinds of Petasites japonicusand its bud, Aralia elata, Aralia cordata, Matteuccia struthiopteris, Pteridium aquilinum var. latiusculum, and Elatostema umbellatum var. majus. More than one-fourth of the respondents from group I buy Aralia cordata, Pteridium aquilinum,and Petasites japonicus; more than one-fourth of the respondents from groups II and III buy Aralia elata and Pteridium aquilinum var. latiusculum. The result of this question reveals that Aralia elata, Aralia cordata, and Pteridium aquilinum var. latiusculum are among the best popular edible wild plants.


#### 3.2.2. Binary Logistic Model: Effects of Age, Education, and City of Residence on Behavior of Purchasing, Collecting, and Eating Edible Wild Plants

We use the binary logistic regression (BLR) to identify relationship of frequency of purchasing, eating, and harvesting and the characterize of respondents. The general form of binary logistic regression is as follows:(1)Probability(y)=11+(Exp-(b0+b1x1+b2x2+b3x3+⋯+bnxn)).Three models are used, wherey1, y2, and y3 are dependent variables and all are binary response variables (0 or 1). y1=1 means the higher frequency of purchasing (more than 1 time one week), y1=0 means others; y2=1 means the higher frequency of eating (more than 1 time one week), y2=0 means others; y3=1 means the higher frequency of harvesting (more than 1 time one week), y3=0 means others. Age, gender, education, the birthplace of the respondents, and the survey site are included in the models.The results of the regression are showed in Table5. Our two models based on binary logistic regression showed significant influence of respondents’ demographic characteristics on their behaviors of purchase, harvesting, or eating edible wild plants (Table 5). Preference differences were found in the respondents with difference in residence of city, age, and education. Respondents from Noto Peninsula had a higher frequency of harvesting and eating edible wild plants than those from Kanazawa City and the other areas. Younger respondents, whose ages were less than 39, were much less involved with edible wild plants. The young group ate, harvested, or bought at a lower frequency than the group older than 40 yrs. Middle-aged group who were in their 40s and 50s harvested less than the respondents older than 60. Respondents with higher education harvested edible wild plants less than those whose education was basic education or lower than basic education.Table 5

#### 3.2.3. Attitude toward Edible Wild Plants

The result of mean points of a Likert scale was calculated as Table7. In this section of the questionnaire, the respondents were asked to check one choice with a number from 1 to 5, which could best represent their attitudes towards the statement. Compare the results of group I and group II, it was found that the respondents from the two groups had little difference of the opinions on the five statements among the total 9 statements. Both the groups strongly agree or agree that sansai is delicious, healthy, and safe food, are one of representative traditional food culture, and environmental friendly without input of chemical fertilizers. Concerning the statements of being cheap, easy to cook, and easy to buy, group I held a more positive attitude toward them than group II.Table 7

#### 3.2.4. Respondents’ Concern towards Edible Wild Plants

In the last part of the questionnaire sheet, respondents were encouraged to write down any comments related to the harvest, consumption of wild edible plants. We got a total number of 64 results: among them 21 were from group I of Noto Region, 34 from group II, and 9 from group III. The results of this part were summarized in Table8. After reading all data, data of open-ended question were categorized into three groups: consumption, harvesting, and others. This part is strongly relevant to the third part of the questionnaire of respondents’ attitude towards wild edible plants.Table 8

They expressed their contentment of being at the production site and harvesting the fresh wild edible plants of rich species. In contrast, respondents from both group II and III expressed difficulty in availability of wild edible plants.Consistent to the above part of questionnaire survey results, respondents emphasized their liking of wild edible plants of being delicious, safe, and healthy. However, about 4 respondents from group II mentioned the difficulty of cooking.Regarding the harvest of wild edible plants, three of the respondents complained about the harvest by outsiders. Six respondents concerned about the sustainable harvest of wild edible plants. The respondents from group II expressed their desire to be accessible to the forested mountain and fresh wild edible plants.


### 3.3. Commercial Harvests and the Attitudes of Forest Owners towards Edible Wild Plants Harvest

Based on the results of questionnaire survey, in-depth interviews were conducted to clarify the attitudes of forest owners and forest managers. Commercial harvesters who might also collect wild edible plants from others’ private forest were reluctant to cooperate with the survey. There is a difficulty of collecting the data of the residents involved with commercial harvest. Japan Agricultural Cooperatives (JA) in Noto Region launched a project to market edible wild plants to the central market in Kanazawa, the capital city of Ishikawa Prefecture. According to the data provided by Anamizu Town Office, JA helped the harvesters from Anamizu Town to sell around 11 species of edible wild plants since 2008. The total sales ranged from JPY 2 million to 8 million (see Table9) during the past three years.Table 9

Head and counselor of FCA were interviewed, respectively. Three forest owners, Mr. and Mrs. Sakamoto and Mr. Kobayashi, were interviewed. Problems listed by FCA and interviewed forest owners include several aspects. First, garbage disposal was listed as the major factor. Secondly, some forest owners partly rely on the edible wild plants for livelihood. The recreational visitors and outside commercial harvesters threaten the benefits of this group. In particular, the prices of edible fungi of high value, for example,matsutake, have multiplied with the increasing demand of fungi in the market. Thirdly, the improper ways of collecting are concerned. Both forest owners and local harvesters mentioned that it will hurt the regeneration in the next year if the roots of wild plants were hurt or taken. Osmunda japonica, a dioecious species, is also a poplar fern sprout. There exists a tradition in Noto Region that only new sprouts of female O. japonica are harvested, while maleO. japonica are left. The new sprouts of some tree species are also edible. For some species such as Aralia elata and Acanthopanax sciadophylloides are not allowed to pick all new leaves, otherwise, the bare tree would wither.In the Noto Region, about 70% of the land is covered with forests, among which private forest consists of 87% of the total forest area (Table10). Our interview with the owners of the private forest found that they generally accept that their friends or residents from the same community to collect wild edible plants from their forested mountain. At the same time, the majority of them are strongly against the intrusion by outsiders from other community, in particular from other prefecture, including the forest recreationists from the urban area. In order to prevent outsiders from entering the forests, access to the forests is prohibited. According to Counselor of Noto FCA, Mr. Yosaburou Yachi, around 60% of the forest was set up with a keep-out sign. Harvesters outside of the community and commercial harvesters are in general prohibited to enter the forest.Table 10

## 3.1. Documentation of Use of Edible Wild Plants

The edible wild plants were compiled with the help of a local vegetation specialist named Fujiko Taniguchi and the reference to some flora books [8–10]. The detail of their habitat, uses as food or medicine, and which part of the plant could be used were tallied. We got a result of around 184 species, belonging to 67 families, which can be used as food both/or medicine in Noto Region (Table 2). Among them, around 176 species belonging to 65 families are edible; around 60 species belonging to 36 families can be used as medicine (Table 3). Almost all parts of the plants can be used, including the sprouts, flowers, fruits, seeds, soft stems, and roots.Table 2

### 3.2.1. Preferences of Edible Wild Plants

In the second part of the questionnaire sheet, the interviewees were asked how frequently they purchase, eat, and collect edible wild plants during the harvest season of edible wild plants from January to June. The results were listed in Table4. From Table 4, we can see that more than 40% of the respondents from the three groups take sansei more than once a week.Table 4

The respondents of group I from Noto Region use and harvest wild edible plants much more often than group II and group III. A big difference was in the frequency of taking and collecting edible plant. Around 78% of the respondents from Group I take sansai more than once a week, comparing to only 42% of respondents from Group II. Around 48% of respondents from group I collectsansai more than once a week, comparing to only 12.9% of respondents from group II. Around 87% of respondents from group II answered that they have only a few or no experience of sansai harvesting. Respondents from group I buy sansai slightly more often than those from group II.Difference was also found in the results of where to buysansai(Table 6). About 61 respondents from group I answered this question, among which 62.3% usually buy from a famers’ market, and 34.4% usually buy from a supermarket. Among the total 77 respondents from group II, around 28.6% of which usually buy from a farmers’ market, and around two-thirds of them usually buy from a supermarket.Respondents were also asked to select the edible wild plant species of three sources; buying, harvesting, and receiving form their relatives.

A big difference was in the frequency of taking and collecting edible plant. Around 78% of the respondents from Group I take sansai more than once a week, comparing to only 42% of respondents from Group II. Around 48% of respondents from group I collectsansai more than once a week, comparing to only 12.9% of respondents from group II. Around 87% of respondents from group II answered that they have only a few or no experience of sansai harvesting. Respondents from group I buy sansai slightly more often than those from group II.Difference was also found in the results of where to buysansai(Table 6). About 61 respondents from group I answered this question, among which 62.3% usually buy from a famers’ market, and 34.4% usually buy from a supermarket. Among the total 77 respondents from group II, around 28.6% of which usually buy from a farmers’ market, and around two-thirds of them usually buy from a supermarket.Respondents were also asked to select the edible wild plant species of three sources; buying, harvesting, and receiving form their relatives. In this question (multiple choice question), around 12 kinds of wild plants, which are commonly used in Ishikawa Prefecture, were listed:Petasites japonicus, Allium schoenoprasum, Aralia elata, Aralia cordata, Allium victorialisvar.platyphyllum, Matteuccia struthiopteris, Pteridium aquilinumvar.latiusculum, Petasites japonicus, Elatostema umbellatumvar.majus,  Oenanthe javanica, Osmunda japonica, and bamboo shoot sprout. The result of this question is closely correlated to that of the previous question of frequency. The result shows that more than one-fourth of the respondents harvest 7 kinds of Petasites japonicusand its bud, Aralia elata, Aralia cordata, Matteuccia struthiopteris, Pteridium aquilinum var. latiusculum, and Elatostema umbellatum var. majus. More than one-fourth of the respondents from group I buy Aralia cordata, Pteridium aquilinum,and Petasites japonicus; more than one-fourth of the respondents from groups II and III buy Aralia elata and Pteridium aquilinum var. latiusculum. The result of this question reveals that Aralia elata, Aralia cordata, and Pteridium aquilinum var. latiusculum are among the best popular edible wild plants.


## 3.2.2. Binary Logistic Model: Effects of Age, Education, and City of Residence on Behavior of Purchasing, Collecting, and Eating Edible Wild Plants

We use the binary logistic regression (BLR) to identify relationship of frequency of purchasing, eating, and harvesting and the characterize of respondents. The general form of binary logistic regression is as follows:(1)Probability(y)=11+(Exp-(b0+b1x1+b2x2+b3x3+⋯+bnxn)).Three models are used, wherey1, y2, and y3 are dependent variables and all are binary response variables (0 or 1). y1=1 means the higher frequency of purchasing (more than 1 time one week), y1=0 means others; y2=1 means the higher frequency of eating (more than 1 time one week), y2=0 means others; y3=1 means the higher frequency of harvesting (more than 1 time one week), y3=0 means others. Age, gender, education, the birthplace of the respondents, and the survey site are included in the models.The results of the regression are showed in Table5. Our two models based on binary logistic regression showed significant influence of respondents’ demographic characteristics on their behaviors of purchase, harvesting, or eating edible wild plants (Table 5). Preference differences were found in the respondents with difference in residence of city, age, and education. Respondents from Noto Peninsula had a higher frequency of harvesting and eating edible wild plants than those from Kanazawa City and the other areas. Younger respondents, whose ages were less than 39, were much less involved with edible wild plants. The young group ate, harvested, or bought at a lower frequency than the group older than 40 yrs. Middle-aged group who were in their 40s and 50s harvested less than the respondents older than 60. Respondents with higher education harvested edible wild plants less than those whose education was basic education or lower than basic education.Table 5

## 3.2.3. Attitude toward Edible Wild Plants

The result of mean points of a Likert scale was calculated as Table7. In this section of the questionnaire, the respondents were asked to check one choice with a number from 1 to 5, which could best represent their attitudes towards the statement. Compare the results of group I and group II, it was found that the respondents from the two groups had little difference of the opinions on the five statements among the total 9 statements. Both the groups strongly agree or agree that sansai is delicious, healthy, and safe food, are one of representative traditional food culture, and environmental friendly without input of chemical fertilizers. Concerning the statements of being cheap, easy to cook, and easy to buy, group I held a more positive attitude toward them than group II.Table 7

A point of 5 refers to strongly agree; 1 point refers to strongly disagree.


## 3.2.4. Respondents’ Concern towards Edible Wild Plants

In the last part of the questionnaire sheet, respondents were encouraged to write down any comments related to the harvest, consumption of wild edible plants. We got a total number of 64 results: among them 21 were from group I of Noto Region, 34 from group II, and 9 from group III. The results of this part were summarized in Table8. After reading all data, data of open-ended question were categorized into three groups: consumption, harvesting, and others. This part is strongly relevant to the third part of the questionnaire of respondents’ attitude towards wild edible plants.Table 8

They expressed their contentment of being at the production site and harvesting the fresh wild edible plants of rich species. In contrast, respondents from both group II and III expressed difficulty in availability of wild edible plants.Consistent to the above part of questionnaire survey results, respondents emphasized their liking of wild edible plants of being delicious, safe, and healthy. However, about 4 respondents from group II mentioned the difficulty of cooking.Regarding the harvest of wild edible plants, three of the respondents complained about the harvest by outsiders. Six respondents concerned about the sustainable harvest of wild edible plants. The respondents from group II expressed their desire to be accessible to the forested mountain and fresh wild edible plants.


## 3.3. Commercial Harvests and the Attitudes of Forest Owners towards Edible Wild Plants Harvest

Based on the results of questionnaire survey, in-depth interviews were conducted to clarify the attitudes of forest owners and forest managers. Commercial harvesters who might also collect wild edible plants from others’ private forest were reluctant to cooperate with the survey. There is a difficulty of collecting the data of the residents involved with commercial harvest. Japan Agricultural Cooperatives (JA) in Noto Region launched a project to market edible wild plants to the central market in Kanazawa, the capital city of Ishikawa Prefecture. According to the data provided by Anamizu Town Office, JA helped the harvesters from Anamizu Town to sell around 11 species of edible wild plants since 2008. The total sales ranged from JPY 2 million to 8 million (see Table9) during the past three years.Table 9

Head and counselor of FCA were interviewed, respectively. Three forest owners, Mr. and Mrs. Sakamoto and Mr. Kobayashi, were interviewed. Problems listed by FCA and interviewed forest owners include several aspects. First, garbage disposal was listed as the major factor. Secondly, some forest owners partly rely on the edible wild plants for livelihood. The recreational visitors and outside commercial harvesters threaten the benefits of this group. In particular, the prices of edible fungi of high value, for example,matsutake, have multiplied with the increasing demand of fungi in the market. Thirdly, the improper ways of collecting are concerned. Both forest owners and local harvesters mentioned that it will hurt the regeneration in the next year if the roots of wild plants were hurt or taken. Osmunda japonica, a dioecious species, is also a poplar fern sprout. There exists a tradition in Noto Region that only new sprouts of female O. japonica are harvested, while maleO. japonica are left. The new sprouts of some tree species are also edible. For some species such as Aralia elata and Acanthopanax sciadophylloides are not allowed to pick all new leaves, otherwise, the bare tree would wither.In the Noto Region, about 70% of the land is covered with forests, among which private forest consists of 87% of the total forest area (Table10). Our interview with the owners of the private forest found that they generally accept that their friends or residents from the same community to collect wild edible plants from their forested mountain. At the same time, the majority of them are strongly against the intrusion by outsiders from other community, in particular from other prefecture, including the forest recreationists from the urban area. In order to prevent outsiders from entering the forests, access to the forests is prohibited. According to Counselor of Noto FCA, Mr. Yosaburou Yachi, around 60% of the forest was set up with a keep-out sign. Harvesters outside of the community and commercial harvesters are in general prohibited to enter the forest.Table 10

## 4. Discussion

### 4.1. Edible Wild Plants as Traditional Food Culture

It was found that there exist abundant edible wild plants in Noto Region, in consistency with some previous studies in other parts of Japan [13–15]. About 200 species can be used as food or medicine, the majority of which were in the forest. Noto Region is a treasure box full of natural and healthy food. A total amount of edible wild plants was estimated to be around 200 species in other parts of Japan. Only about 15% of them were eaten by local residents [17, 18].This study revealed that people living in Noto Region, as well as those in nearby urban areas have very close connection to edible wild plants as that a majority of the respondents have eaten, bought, and harvested them very often during the harvest season of edible wild plants. Respondents surveyed had a positive attitude towards edible wild plants. Edible wild plants were labeled by a majority of respondents from remote mountainous areas as well as from urban areas as being tasty, healthy, and safe food. Edible wild plants are considered to be representative traditional food related to local culture.Some early researches [13] also reported that the people of Japan have considered edible wild plants as tasty food [14, 15]. It was also reported that Japanese consumers considered edible wild plants as expensive, while, this survey found that consumers in Noto Region considered the prices as reasonable. Comparing with reports in other areas or in previous year, respondents in this survey had a more positive assessment of edible wild plants.Survey also found Farmers’ Market as an important marketing channel of wild edible plants, in particular in Noto Peninsula. In contrast, around two-thirds of consumers in metropolitan city bought from a supermarket or a vegetable store [16].With the ageing and depopulation in rural areas, the traditional knowledge related to edible wild plants is facing the threat of degradation. The loss of traditional ecological knowledge associated with wild plants negatively affects the lives and health of traditionally living rural communities [19]. Although numerous previous studies report that traditional knowledge related to wild edible plants has greatly declined in Africa [19] and Japan [4], due to the impacts of the drivers of ageing and migration. Findings in this study revealed that residents from not only the mountainous areas and urban areas hold very positive attitude towards edible plants and their lives are closely related to wild plants. A majority of respondents agreed that edible wild plants are important part of their traditional diet. Traditional knowledge related to eating and harvesting edible wild plants are still passed on, while at some extent declining. How to maintain and dissimilate the traditional knowledge related to wild edible plants must be considered as part of revitalization of rural area in Japan. Young generations must be the foci of education of traditional ecological knowledge. Urban residents from the nearby cities should be included as potential recreationists from the aspects of dynamically conserving traditional culture, in particular endemic dietary and revitalizing rural areas by enhancing the attractions of forest and nature to increase visitors to remote areas.


### 4.2. Challenges to Develop the Recreational Uses of Edible Wild Plants

Abundant species of edible wild plants and being able to access low hills (satoyama) without wild boars or bears in Noto Peninsula have attracted not only local residents but also urban residents from Ishikawa Prefecture and even other prefectures to harvest sansai. It was found in this study that private forest owners do not consider these outsiders desirable.Many studies [20] found the importance of continued public ownership and of continued (and enhanced) multiuse management strategies. Thus, we assume that private ownership of forest resources is a major impediment to recreational use of nature resource. In Japan, private forests hardly participate in providing recreational activities, and researches related to recreational activities on private land or by privately funds are very rare [21].Recreational use of forests must be reevaluated since forests are considered to be multifunctional. Forest and Forestry Basic Act was radically revised based on Basic Forestry Law (1964) and enacted in 2001. It designates the basic principles for forest policies in the 21st century. In this act, it places the sustainable development of multi-functions of the forest as the basic ideology. Among the multi-functions of the forest mentioned in this new Forest and Forestry Basic Act, recreational function of the forest as to enhance public health was evaluated the same as other forest products.Maintaining NTFP resources was less critical for the subsistence needs of the majority of the public and therefore did not rank high as a management priority. The emphasis may have shifted from subsistence to commercial and recreational pursuits, harvesting [22]. Commercial harvesting and marketing of edible wild plants in Noto Region are still far from being successful given the small amount and unsteady growth of the total amount and price (Table 8).

## 5. Conclusion

With the rapid urbanization, increase of abandoned farmlands and undermanaged forests in the past decades, the changing rural landscape has posed threats towards the loss of biodiversity and associated environmental services. It is evident that interest has been given to biomass production and restoration of ancient woods in the coppice woodlands, while little attention so far has been paid to the social dimension. There is a danger of neglecting the potential for coppices as socially important woodland types. Traditional knowledge has been emphasized as the most promising cognitive response to the balance of protection ofsatoyama landscape and other traditionally managed forest [23] and sustainable use of natural resources. A FAO’s Globally Important Agricultural Heritage System (GIAHS) pilot site in the Noto Peninsula was designated to foster dynamic conservation and sustainable use of local natural resources.Our survey in Ishikawa Prefecture found that there exist abundant species of edible wild plants insatoyama, and local people not only from remote areas but also from urban areas have highly positive attitude towards edible wild plants. Developing the sustainable use of natural resources in satoyama by promoting the harvest and consumption of edible wild plants could be considered as an important means of rural vitalization. It was found that farmers’ market of Japan Agricultural Cooperatives (JA) has played a vital role in marketing edible wild plants. Young respondents had a low frequency of consuming edible wild plants. One of our findings is consistent with previous studies [17, 18] that it is an urgent issue to educate young people with traditional knowledge in order to prevent from the loss of relevant traditional culture.NTFP extraction does not have to be seen as a threat to biodiversity, but rather can be seen as a tool for creating socioeconomic relationships that are dependent on healthy, biodiverse ecosystems. It has been argued that anthropogenic disturbance of intermediate impact has developed rich biodiversity in the secondary forest [24]. Some local residents considered that edible wild plants collectors from other communities including urban residents will threaten their interest.An early report recommended having forest recreationists pay a right of access to harvesting wild edible plants [25]. Japan Satoyama Satoumi Assessment [2] recommends the idea of the “new commons” to create a new management system by local government and NPOs and NGOs [2]. In particular, we argue that “new commons” should include urban residents to access the forests for nontimber forest product, for example, edible wild plants. In Nordic European countries, there is the traditional right of “Everyman’s right,” which includes berry picking, mushroom collecting, and free access for all recreation and sports activities [26]. It is obvious that, in Japan, the customary law with limiting the access of residents from other communities, and the current private ownership have excluded the urban residents to access the forested hills. It is suggested that those private forests which were abandoned in terms of management in remote region could be accessible to urban residents for obtaining wellbeing of forest resources through the administrative supports at some extent. JA and Forestry Cooperatives (FCA) should play an important role in achieving the GIAHS goal of dynamic conservation and sustainable management in the Noto Peninsula.
