Abstract
Purpose
The purpose of this paper is to explore the availability and use status of plant species and their genetic diversities from local forests and uncultivated lands in the context of three different Chepang ethnic communities of Nepal. In the current context of increased threats upon the natural resources to meet increased food demand, unsustainable harvest is also practised, leading to unavailability of the diversities, thus conservation and sustainable harvest were compared along with contribution of those neglected and underutilized species for food, nutrition and livelihood security of the local dwellers.
Design/methodology/approach
This research was done by using multi-stage random sampling of 15 households from each village development committee (VDC), namely Shaktikhor, Kaule and Siddhi of Chitwan district of Nepal. The farmers’ participation in this study was ensured through participatory research methods, including group discussions (GD) and other Participatory Rural Appraisal (PRA) tools. In addition, field observations, household interviews and consultation with experts were used in this study.
Findings
The Chepang community was found to possess immense knowledge on forest products and crop landraces and utilize the various plants for food and medicine. The underutilized species were used by the local people in different forms (food, vegetables, medicine, and for cultural and economical reasons). The uses of 46 underutilized plant species were documented, including 25 species with multiple functions as food, vegetables, and medicines. The overall contribution was about 2.7 months a year, with a significant difference between Siddhi (3.8months), Shaktikhor (2.4 months) and Kaule (1.9 months).
Research limitations/implications
This research was an exploratory action research covering only 45 households from three VDCs and is not an adequate sample size considering population size. Due to differences in the altitude, farm and family size, level of education, the number of species availability and uses may differ and this research needs to be replicated covering different seasons, years and more respondents.
Originality/value
This piece of research is original and conducted by three researchers working with different institutions. This strongly showed a gradual loss of the plant genetic diversities due to inability of the state, through its policy and programs, to recognize the contribution of those species in food, nutrition and livelihood security of vulnerable populations. The state should emphasize on research, education and technology development for those undermined crops, despite their huge contribution to the livelihood system.

Abstract
Purpose
The purpose of this study is to evaluate the pattern of carotenoids distribution in three underutilized Malaysian ‘ulam’ or traditional vegetables in Malaysia (Averrhoa carambola, Manihot esculenta and Ipomoea batatas) and their valuable pro-vitamin A activities. These assessments will yield valuable knowledge and insight into the importance of these underutilized traditional vegetables and highlight their potential for applications in medicinal and functional colorant industries.
Design/methodology/approach
In this study, the authors have evaluated the distribution of carotenoid compounds in aerial organs of three underutilized traditional vegetables (Averrhoa carambola, Manihot esculenta and Ipomoea batatas). The content of the individual carotenoids were quantified using high-performance liquid chromatography (HPLC) and the organ with the highest accumulation of these compounds were identified. Their valuable pro-vitamin A activities were also reported to indicate their medicinal potential which can further be exploited as pharmacologically active natural colorants and in other applications.
Findings
In total, three major chromatographic peaks corresponding to lutein, violaxanthin and β-carotene were observed through HPLC. Among the compounds detected, lutein and β-carotene were the most abundant carotenoids found in both shoots and petioles of all three species. Violaxanthin was only detected in I. batatas shoots. Overall, carotenoid content was observed to be higher in the shoots than in the petioles, where I. batatas contained the highest amount of total carotenoid, followed by M. esculenta and A. carambola. The opposite trend was observed in the petioles, where A. carambola petioles had the highest carotenoid content, while I. batatas contained the least.
Research limitations/implications
The distribution and abundance of these individual carotenoids suggested that the petioles contained the highest amount of carotenoid, contributing to its high pro-vitamin A activity, and could be potentially useful for medicinal application, as it can act as storage site that is not as prone to natural drying or degradation during harvest and sample storage. Future research work should include improvements in the extraction and purification procedures as well as robust identification methods which may lead to better detection and identification of other compounds that could attribute to its bioactivity, to complement the findings of the current study.
Practical implications
This analysis provides valuable information on the importance of underutilized traditional vegetables as important biofactories for sustainable production of valuable pigments (such as carotenoids) with medicinal benefits and can further be exploited in various industries, such as in formulation of functional natural colorants. This study also highlights the importance of petiole as a storage site of pharmacologically active compounds that is not as prone to natural drying or degradation during harvest and sample storage.
Originality/value
To date, there is no previous report found on comparative analysis of carotenoid content and quantification of individual carotenoid concentration in the edible aerial parts of Averrhoa carambola, Manihot esculenta and Ipomoea batatas, although they have been traditionally consumed as “ulam” in Malaysia. Therefore, the results reported in this study provide new insights on carotenoid accumulation in the selected ‘ulam’ species.

Abstract
Purpose
African indigenous vegetables have high nutritive value which contains high levels of minerals. The current status of indigenous vegetable production in developing countries shows that these crops are “under-recognized” and “underutilized” with respect to nutritional value and opportunities for food security. The purpose of this paper is to examine the impact of the production of underutilized vegetables on the livelihood of farmers in South Western Nigeria.
Design/methodology/approach
The population for the study includes all the vegetable farmers in South Western Nigeria with a special focus on farmers’ groups formed by the NICANVEG project in Osun, Oyo, Ondo and Ekiti states. Descriptive statistics and propensity score matching (PSM) was used to analyze the objective.
Findings
Perceptions on individual household income reveal that the majority of participating respondents perceived higher production and harvesting density. This is due to the fact that harvesting is done by cutting the stems of the vegetables. The probability score shows that the dependent variables have an average effect of 44.6 percent on the probability of farmers participating in NICANVEG project. The PSM results reveal that average treatment effect on the treated is ₦269,254.87. Average treatment on the untreated is ₦11,990.63 while average treatment effect is ₦139,336.43. The total income of the participants from all the various livelihood strategies is increased by 29.73 percent because of their participation in the NICANVEG project.
Originality/value
This work has not been carried out by any other person before. This work will add to the existing knowledge on the impact of evaluation in agricultural economics.

Abstract
Purpose
The paper aims to study the applicability of Lefebvre's everyday life theory “production of space” in Sheraton's in-between spaces upon local residents' daily practices. Space as Lefebvre said is a result and cause, product and producer. Sheraton District, Cairo comprises lots of underutilized spaces between buildings. The in-between spaces have great potentials for accommodating diverse activities. The present study addresses the phenomenon of in-between spaces in this district. It is argued that in-between spaces can be developed to realize better functional and symbolic values, as the users attach special meanings based on users' everyday living.
Design/methodology/approach
The study adopts a qualitative approach to investigate the above relationship on the mentioned district. The study devises direct observation to investigate people's behavioral patterns in such appropriated areas to analyze them in the light of preceding literature.
Findings
The study concludes that people's everyday practices could re-invent the in-between spaces by realizing new functions and meanings in dynamic and creative ways. That experience can apply to other underutilized spaces in the district and the city toward improving the built environment and the quality of residents' life.
Research limitations/implications
Finally, it is important to note that the findings of the study are limited to the studied context. Undertaking similar studies to other in-between spaces in Cairo, in other Egyptian cities or other countries may yield different findings. It may be equally interesting to study the means of adaptation in other underutilized urban spaces, such as those found underneath bridges, underneath buildings and on the rooftops.
Originality/value
The main aim of the present study is to examine the impact of everyday practices on the appropriation of a transformed in-between space in the aforementioned district, and the extent to which that may improve in-between spaces' role toward the local community, in order to promote such approach for developing many underutilized in-between spaces in the area. Toward realizing this goal, the study begins with a theoretical background about everyday life. Then, the paper addresses the theory of space appropriation. The outcome is then empirically investigated in relation to one transformed in-between space in Sheraton District, Cairo.

Abstract
Purpose
The purpose of this paper is to examine whether the different employment statuses of under‐employment, temporary employment, unemployment and non‐participation in the labor force are associated with perceived well‐being among persons with disabilities.
Design/methodology/approach
The authors used data from the 2006 Participation and Activity Limitation Survey (PALS) conducted by Statistics Canada to develop six categories of employment status. OLS regression analysis was used for hypothesis testing.
Findings
Findings indicated that fully utilized permanent employees show the highest level of life satisfaction while unemployed persons searching for work have the lowest levels of life satisfaction and the highest levels of perceived workplace discrimination. Permanent employees whose skills are greatly underutilized show the second‐lowest level of life satisfaction and equally high perceived workplace discrimination as unemployed persons. Non‐participants in the labor force show life satisfaction levels similar to those of permanent moderately underutilized employees as well as temporary employees, but report relatively little workplace discrimination.
Originality/value
The study links vocational status to the psychological well‐being of persons with disabilities in a large representative sample covering the full spectrum of disability types and occupational statuses. As such, it validates conclusions from smaller studies examining single organizations or focusing on workers with specific types of disabilities.

Abstract
Purpose
It is very pertinent to determine the nutritional value of indigenous leafy-vegetables to establish their potentials in ensuring adequate nutrition and food security. One of the ways to promote fresh produce is through nutritional information. The paper aims to discuss these issues.
Design/methodology/approach
Simultaneous multi-element analysis of eight indigenous (with underutilized) vegetables commonly found in the Southwest Nigeria was done by inductively coupled plasma-atomic emission spectroscopy. Wild-grown vegetables were harvested from the National Horticultural Research Institute orchard, in Southwest Nigeria. The contents of investigated quantity minerals as well as trace and heavy metals were determined.
Findings
In all the vegetables, potassium was discovered as the most abundant quantity mineral present with range of 4.364 mg/g in Vernonia amygdalina to 78.218 mg/g in Senecio biafrae (an underutilized vegetable). This was followed by calcium ranging from 3.351 mg/g (Vernonia amygdalina) to 9.914 mg/g (Solanum macrocarpon). Lead had the least content among the heavy metals with range of value from below the detection limit of the method used to 0.05 μg/g.
Practical implications
The results obtained for the mineral profile provide useful information that could sensitize the people on the need for their consumption. This can be a good opportunity to enhance micronutrient supply of the diet of low-income earners which form majority of the society.
Originality/value
Findings from this study indicate that the indigenous vegetables that are not formally cultivated could be important in improving micronutrient deficiency of low-income earners.

Abstract
Art therapy has been recognized as beneficial and effective since first described by Adrian Hill in 1942. Even before this time, art therapy was utilized for moral reinforcement and psychoanalysis. Art therapy aids patients with, but not limited to, chronic illness, physical challenges, and cancer in both pediatric and adult scenarios. Although effective in patient care, the practice of art therapy is extremely underutilized, especially in suburban areas. While conducting our own study in northeastern Ohio, USA, we found that only one out of the five inpatient institutions in the suburban area of Mahoning County, Ohio, that we contacted provided continuous art therapy to it's patients. In the metropolitan area of Cuyahoga County, Ohio, only eight of the twenty-two inpatient institutions in the area provided art therapy. There could be many reasons as to why art therapy is not frequently used in these areas, and medical institutions in general. The cause of this could be the amount of research done on the practice. Although difficult to conduct formal research on such a broad field, the American Art Therapy Association has succeeded in doing such, with studies showing improvement of the patient groups emotionally and mentally in many case types.

Abstract
Purpose
The aim of the study is to compare the effect of steaming method and time on the physico‐chemical properties of underutilized Dioscorea dumetorum with three more commonly consumed Dioscorea rotundata, Dioscorea cayenensis and Dioscorea alata.
Design/methodology/approach
Raw and pre‐gelatinized flour were produced from the yam species. Pre‐gelatinization was done by steaming diced cubes in autoclave at 68,950 Nm‐2 for 5 min and in Barlett steamer at 98±2°C for 10, 20 and 30 min. Flour samples were analyzed for amylose content, swelling index, consistency, solubility, water absorption capacity, and iodine affinity for starch.
Findings
The physico‐chemical properties of the flours were affected by both species and steaming time. Pre‐gelatinization of the tuber reduced amylose content in all the yam species, which reduced further with increase in steaming time. Except for amylose content and iodine affinity for starch, D. dumetorum compared with D. rotundata and D. cayenensis in the parameters that were measured. Samples autoclaved for 5 min had value similar to those steamed in Barlett steamer for 10 and 20 min for all the parameters that were measured, except consistency.
Practical implications
It is very important to encourage the cultivation and utilization of D. dumetorum because of the high yield and nutritional composition to enhance the nutritional and financial well‐being of the populace.
Originality/value
Pre‐gelatinization is important as pre‐treatment for yam tubers. Underutilized D. dumetorum could be useful in ingredient formulation for product development, especially as a thickening agent.

Abstract
In 1996, GAO reported that the State Department did not have an effective process for identifying and selling unneeded overseas real estate, and that decisions concerning the sale of some properties had been delayed for years because of parochial conflicts among the parties involved. The State Department has taken steps to implement a more systematic process for identifying unneeded properties by (1) requesting posts to annually identify excess, underutilized, and obsolete property and (2) requesting its own staff and Inspector General officials to place greater emphasis on identifying such property when they visit posts. The State Department has significantly increased its sales of unneeded properties in the last 5 years. From 1997 through 2001, it sold 104 overseas properties for over $404 million, almost triple the proceeds compared with the previous 5-year period. However, the department still has a large number of unneeded properties that have not yet been sold. The State Department has not effectively implemented recommendations made by the Real Property Advisory Board to sell unneeded property. State has disposed of only 7 properties of the 26 recommended for sale by the board.

Abstract
Purpose
The paper aims to investigate the iron, zinc, carotenoid, vitamin E, anthocyanin, and phenolic contents, antioxidant activity and the effect of the boiling of rice on such parameters.
Design/methodology/approach
Iron and zinc content were investigated using atomic absorption spectrometry. Meanwhile, simultaneous extraction and detection methods using high performance liquid chromatography were applied for carotenoids, tocopherol, and tocotrienol analyses. For anthocyanin and phenolic determination, pH differential method and Folin Ciocalteu method were used, respectively. Antioxidant activity of samples was examined using ferric reducing antioxidant power (FRAP) and superoxide radical scavenging methods.
Findings
The n790 cultivar has a higher iron, zinc γ tocopherol (1,869.64 mg/kg), α tocopherol (1,883.97 mg/kg), anthocyanin (205.54 mg cyanidin 3 glucoside equivalent/100 g dry matter), and phenolic (728.9 mg catechin equivalent/100 g dry matter) contents. Jowo cultivar has higher lutein (1,314.21 mg/kg), α carotene (823.29 mg/kg), and β carotene (71.73 mg/kg) contents. Meanwhile, γ tocotrienol is the most abundant tocotrienol found in all samples. N790 cultivar had the highest antioxidative potential in FRAP, and superoxide radical methods. Boiling did not significantly affect the zinc content, however, different response was found in carotenoid, tocopherol, and tocotrienol content. Moreover, boiling decreased the antioxidant activity of extract.
Practical implications
Black- and red-colored rice could substitute white rice in Indonesian diet to achieve better nutrient intake.
Originality/value
Providing information on nutrient and bioactive compound of Indonesian underutilized colored rice can help to change the dietary habit and to alleviate nutrient deficiency in Indonesia.
