Wild Edible Fruits: A Systematic Review of an Under-Researched Multifunctional NTFP (Non-Timber Forest Product)

Wild edible plants of the Yao people in Jianghua, China: plant-associated traditional knowledge and practice vital for food security and ecosystem service

BACKGROUND

Traditional ecological knowledge (TEK) and practice associated with wild edible plants (WEPs) is an important part of local culture of the Yao people in Jianghua Yao Autonomous County, which possesses the biggest population of Yao ethnic group in China. Economic development, urbanization, and transition of lifestyle and changing interests of the younger generations risk loss of such valuable knowledge. However, no record had been reported about WEPs from the Yao communities of Jianghua County. It is urgent to assemble data on the major WEPs and their uses in Jianghua. This can be used to educate and stimulate new interest in these WEPs, to aid inheritance and improvement of cultural identity and confidence, to enhance local resilience to various changes and to suggest pathways for novel and value-added applications to create new local business opportunities.

METHODS

To record WEPs associated with TEK and practice, we conducted field surveys in 2018, 2019 and 2023. The ethnobotanical methods such as free-listing, participatory observation, semi-structured interview, and market survey were adopted in the field investigations. Information about WEPs including vernacular names, parts used, ways of use, and collection time were recorded. Voucher specimens were collected, identified, and deposited in the herbarium at Minzu University of China, in Beijing.

RESULTS

Totally, 81 Yao people from 12 villages were interviewed. WEPs traditionally play a crucial role in Yao peoples' daily lives. A total of 130 plant species from 89 genera and 49 families were recorded. The plants collected showed great diversity and reflected unique local culture. Most (54.5%) WEPs were also used as medicines. Baba can be defined as a cultural identity food, and WEPs are commonly used as tea substitutes for their health benefits.

CONCLUSIONS

We conclude that WEPs use is facing great challenges in a rapidly changing era. Preservation of WEPs related practice and knowledge is not only important for conserving local biocultural diversity, but also valuable in providing potential functional and healthy materials for food security and future economic development. Cultivation of young generations' interest in nature and biodiversity, combined with local policy to enhance public awareness are recommended.

Ethnobotanical study of wild edible plants in Dibatie district, Metekel zone, Benishangul Gumuz Regional State, western Ethiopia

BACKGROUND

Plants deliver livelihood and food for millions of people in the world. Indeed, wild edible plants support rural communities in developing countries to overcome seasonal unfavorable conditions. In rural areas of Ethiopia, wild edible plants play an indispensable role in fighting food insecurity as emergency or supplementary foods. Hence, this research was aimed at studying the ethnobotanical assessment of wild edible plants in Dibatie district, Metekel zone, western Ethiopia.

METHODS

Ethnobotanical data was collected using a semi-structured interview, field observation, focus group discussions, a market survey, and the ranking of selected plants. Besides, voucher specimens were collected and stored at the National Herbarium of Ethiopia. Descriptive statistics, preference ranking, direct matrix ranking, and familiarity index were computed for data analysis.

RESULTS

This study has documented 54 wild edible plant species belonging to 33 plant families and 46 genera. Of these, most (38.90%) had tree growth habits. Wild edible plants bear mostly fruits (72.20%) as edible parts. Local people usually consume these plants freshly raw as complementary foods, though some wild edibles require processing. They were mostly harvested in the January (31.48%) and May (27.78%) months, with the least collected in September (7.41%). Most wild edible plants (78.57%) were available in uncontrolled habitats, while others (21.43%) live in farmlands, home gardens, and as live fences. Out of the recorded plants, about 98% had additional uses besides their nutritional values.

CONCLUSION

Wild edible plants assist the livelihoods of the local people in food security, agriculture, energy sources, construction, medicines, ecological services, aesthetics, income generation, and household utensils. Nevertheless, wild edible plants are recently threatened due to various anthropogenic factors in the study area. Thus, they need wise use and in-situ and ex-situ conservation measures from all the concerned bodies for sustainable use in the future.

An ethnobotanical study of wild edible fruits in miombo woodlands of Tabora region in Western Tanzania

BACKGROUND

Wild edible fruits found in Tanzania's miombo woods are an indispensable source of food and medicine. Unfortunately, with the rapid expansion of human activities and urbanisation in the Tabora rural, Uyui and Sikonge districts of Western Tanzania, some wild fruits are disappearing due to the loss of plant diversity. The objectives of this study wereL: to document the knowledge related to wild edible fruits; to quantify the use and cultural significance, and to determine their threats.

METHODS

The ethnobotanical study was conducted from June 2022 to February 2023 involving 244 local informants. The study used field visits, the collection of plant parts, and semi-structured interviews with locals for its data collection. Descriptive statistics and correlation test were used to analyse the knowledge related to wild fruits. Frequency citation (f) and use reports (UR) were computed to understand the diversity and cultural significance (CI).

RESULTS

The study documented 27 wild edible fruit species used for food and medicine. The life form constituted deciduous shrubs or trees (64%), shrub trees (21%) and evergreen or deciduous trees (15%). About (56%) of wild edible fruits were collected from June to August after the rainy season, (33%) were harvested between December and May during the rainy season, and (11%) were gathered from September and November before the rainy season. Household size and sex of the respondents were significantly correlated to the knowledge of wild edible fruits. Higher utilisation frequency (f) was recorded for Vitex mombassae Vatke (f = 0.84), Strychnos spinosa Lam. (f = 0.82), Vitex payos (Lour.) Merr. (f = 0.56), Phyllogeiton discolor (Klotzsch) Herzog. (f = 0.45), Vangueria infausta Burchell (f = 0.45), Tamarindus indica L. (f = 0.38), Parinari curatellifolia (f = 0.25), Landolphia parvifolia K.Schum. (f = 0.22) and Microcos conocarpa Burret (f = 0.22) fruits species. Additionally, Phyllogeiton discolor (Klotzsch) Herzog. (UR = 56), Vitex mombassae Vatke (UR = 56), Tamarindus indica L. (UR = 37), Strychnos spinosa Lam. (UR = 14) and Friesodielsia obovata (Benth.) Verdc. (UR = 11), have higher use reports (UR) and considered culturally important. Wild fruits were used to cure diabetes, gastrointestinal, reproductive, and respiratory infections ailments.

DISCUSSION AND CONCLUSION

Multiple uses as well as the related knowledge of wild fruits have been documented. Friesodielsia obovata, Grewia flavescens Juss and Thespesia garckeana F.Hoffm. are the medicinal fruit species reported for the first time. Harvesting of wood plants, charcoal activities, crop cultivation, grazing expansion, and environmental change, have had an impact on the diversity of wild edible fruit plants. Over the past three decades, the use of wild fruits has been impacted by the loss of plant diversity due to decline of cultural norms on the forests management. Given the variety of uses for wild fruits, promoting markets for native fruits, sensitising the locals about the cultural importance and innovation on processing techniques are necessary to spur conservation efforts.

Effect of storage condition on the nutritional and anti-nutritional composition of kurkura (Ziziphus mauritiana Lam.) fruit from North-Eastern Ethiopia

Ziziphus mauritiana is used as food and medicine. It is very nutritive and contains high amounts of calcium, phosphorus, iron, vitamin C, and beta-carotene. To choose an appropriate technique for fruit preservation, this study evaluated the effect of temperature and time on the nutritional and anti-nutritional qualities of Ziziphus mauritiana fruit harvested from Kobo Woreda in North-Eastern Ethiopia. This study assessed the impact of preservation parameters on the nutritional and anti-nutritional properties of Ziziphus mauritiana fruit, such as storage temperature and preservation day (time). Ziziphus mauritiana fruit was also analyzed to evaluate storage temperature and preservation day on its nutritional and antinutritional composition and found moisture content (5.25-10.99%), ash content (4.74-10.70%), crude fiber (3.81-17.88), fat (0.49-2.16), nitrogen content (1.01-1.8%), protein content (6.33-11.27), phytate content (67.27-659.33 mg/100 g m), and tannin content (3842.46-16577.80 mg/100 g m). The findings revealed that both individual and interaction effects were highly significant differences (p-value, 0.0001) in each nutritional and antinutritional content of the fruit. The results of this study showed that it was possible to store Ziziphus mauritiana fruit using plastic bags (High-Density Polyethylene Bags), and further deep-freezing the fruit had the best effect on preserving it in its fresh state (without damage) for up to 45 days.

Contribution of Nontimber Forest Products Earn to Livelihood in Rural Households and the Type of Use: A Systematic Review

The researcher conducted a review of 83 articles published between 2011 and 2021 to determine the nontimber forest products (NTFPs) income contribution and usage types based on spatial and temporal patterns. The study used a search, synthesis, appraisal, and analysis framework for review. The review included articles that only focused on the contributions of NTFPs for livelihood income and NTFPs usage type, while others not related to these two topics were excluded. For its literature search, more than half of the articles used Google Scholar, followed by Research4life, Scopus/Elsevier, EMBASE, and PubMed, respectively. In this study, excluding papers that (i) did not provide evidence on the income contribution of NTFPs, (ii) did not include articles that did not clearly explain the NTFPs use types, and (iii) were published before 2011, the reviewer was able to reduce the number of included articles (eligibility criteria or inclusion and exclusion criteria). 83 article papers were reviewed for the current review. The majority of the research for this review was carried out in India (19%), Ethiopia (13%), and Nigeria (11%). India was the first of the 17 both Asian and African countries to do research on the NTFPs’ contribution to rural household income and type of use. NTFPs contribute significantly to rural household revenue in 17 countries, ranging from a minimum of 9.5% in Zambia to a maximum of 40.19% in Myanmar. The average percentage of revenue from NTFPs across the 17 nations was 23.56%. Wild fruit, wild vegetables, medicinal plants, firewood, and crafts were the five NTFP usage types that were used by people in every country studied. Despite the fact that different countries utilize different types of NTFPs, the most commonly used types of NTFPs do not differ statistically ( $P>0.05$ ). To prevent overexploitation, those top five NTFPs must be conserved as they gather across the regions. NTFP collection is a significant source of revenue for rural poor and people who live in and around the forest. There are many types of NTFPs in both Asian and African countries. So, this study shows that the rural people depend on the forest product and get many benefits from the forest especially in the NTFP usage type. In order to secure livelihood stability in this global biodiversity hotspot and to preserve plant and animal diversity, the cultivation and scientific harvesting of NTFPs are urgently required. It is necessary to increase capacity by teaching NTFP users how, when, and how much to harvest.

Screening of Naturally Grown European Cranberrybush (Viburnum opulus L.) Genotypes Based on Physico-Chemical Characteristics

It has become very important to offer species with high nutritional value as fresh or processed products for human consumption in their daily diet for balanced nutrition. In the scope of this study, 15 naturally grown European Cranberry bush (ECB) genotypes that naturally grown were characterized in terms of horticultural characteristics. Fruit length, fruit width, fruit weight, the number of fruits per each cluster and cluster weight were determined within the ranges of 8.78−10.96 mm, 7.93−10.84 mm, 0.21−0.70 g, 31−121, and 7.70−66.67 g, respectively. Ranking of the average values of examined organic acids obtained from all genotypes found as; malic acid (11,419 mg L−1) > citric acid (1926 mg L−1) > ascorbic acid (581 mg L−1) > oxalic acid (561 mg L−1). Total phenolic content (TPC) and total flavonoid content (TFC) were found at high levels in ECB with 2922−3475 mg gallic acid equivalent (GAE) L−1 and 1463−3163 mg quercetin equivalents (QE) L−1, respectively. While pomological characteristics were found to be highly positive correlated with each other, they were negatively correlated with chemical properties. Low pH was found to be an important parameter to obtain higher amounts of phytochemicals such as TPC, TFC, organic and phenolic acids correlated with strong antioxidant effects. The obtained results will be useful for both germplasm enrichment and cultivation.

Functional Traits, Species Diversity and Species Composition of a Neotropical Palm Community Vary in Relation to Forest Age

Understanding the factors that shape the diversity and composition of biotic communities in natural and human-modified landscapes remains a key issue in ecology. Here, we evaluate how functional traits, species diversity and community composition of palm species vary in relation to biogeographic variables and forest age in northwest Ecuador. Functional traits capture essential aspects of species’ ecological tradeoffs and roles within an ecosystem, making them useful in determining the ecological consequences of environmental change, but they have not been used as commonly as more traditional metrics of species diversity and community composition. We inventoried palm communities in 965 10 × 10 m plots arrayed in linear transects placed in forests of varying age. Adult palms in forests of younger regeneration stages were characterized by species with greater maximum stem height, greater maximum stem diameter, and solitary stems. The shift in functional features could indicate that shade tolerant palms are more common in old-growth forest. The shift could also reflect the legacy of leaving canopy palms as remnants in areas that were cleared and then allowed to regrow. Moreover, younger forest age was associated with decreased abundance and altered species composition in both juvenile and adult palms, and decreased species richness in adults. These results highlight the importance of retaining intact, old-growth forest to preserve functional and species diversity and highlight the importance of considering multiple aspects of diversity in studies of vegetation communities.

Potentials and Opportunities of Wild Edible Forest Fruits for Rural Household’s Economy in Arasbaran, Iran

Non-timber forest products (NTFPs) contribute to local people’s livelihood in many regions around the world. This article investigates the types of NTFPs collected, processed, and traded in the Arasbaran region of Iran, the roles of these products in household economies, and the potential contribution to rural household economies through the collection, processing, and marketing of NTFPs. Data were collected using household and community surveys as well as through secondary sources on the role of NTFPs within Arasbaran forests in Iran. The main NTFPs harvested by local people were fruits. The fruits from 14 woody species, including trees and shrubs, were harvested by local people. The average share of forest-harvested fruit to household income was 27 percent. The mean annual income derived from the harvest and sale of sumac and reddish blackberry in the sample rural household incomes was USD 1822 and USD 142, respectively. In regard to processing efficiency, plum, cornelian cherry, and sumac exhibited the highest processing efficiency. Better policy support would be needed along the whole value chain, starting with the forest management plans, to include fruit species. In addition, measures to support processing facilities as well as to promote trade and marketing beyond the local area would be highly important to develop the potential of forest fruits and other NTFPs. Besides technical and financial support, measures should include regulatory revisions as well as information, training, and awareness raising.

The Future of Food: Domestication and Commercialization of Indigenous Food Crops in Africa over the Third Decade (2012–2021)

This paper follows the transition from ethnobotany to a deeper scientific understanding of the food and medicinal properties of African agroforestry tree products as inputs into the start of domestication activities. It progresses on to the integration of these indigenous trees as new crops within diversified farming systems for multiple social, economic and environmental benefits. From its advent in the 1990s, the domestication of indigenous food and non-food tree species has become a global programme with a strong African focus. This review of progress in the third decade is restricted to progress in Africa, where multi-disciplinary research on over 59 species has been reported in 759 research papers in 318 science publications by scientists from over 833 research teams in 70 countries around the world (532 in Africa). The review spans 23 research topics presenting the recent research literature for tree species of high priority across the continent, as well as that in each of the four main ecological regions: the humid zone of West and Central Africa; the Sahel and North Africa; the East African highlands and drylands; and the woody savannas of Southern Africa. The main areas of growth have been the nutritional/medicinal value of non-timber forest products; the evaluation of the state of natural resources and their importance to local people; and the characterization of useful traits. However, the testing of putative cultivars; the implementation of participatory principles; the protection of traditional knowledge and intellectual property rights; and the selection of elite trees and ideotypes remain under-researched. To the probable detriment of the upscaling and impact in tropical agriculture, there has been, at the international level, a move away from decentralized, community-based tree domestication towards a laboratory-based, centralized approach. However, the rapid uptake of research by university departments and national agricultural research centres in Africa indicates a recognition of the importance of the indigenous crops for both the livelihoods of rural communities and the revitalization and enhanced outputs from agriculture in Africa, especially in West Africa. Thus, on a continental scale, there has been an uptake of research with policy relevance for the integration of indigenous trees in agroecosystems and their importance for the attainment of the UN Sustainable Development Goals. To progress this in the fourth decade, there will need to be a dedicated Centre in Africa to test and develop cultivars of indigenous crops. Finally, this review underpins a holistic approach to mitigating climate change, as well as other big global issues such as hunger, poverty and loss of wildlife habitat by reaping the benefits, or ‘profits’, from investment in the five forms of Capital, described as ‘land maxing’. However, policy and decision makers are not yet recognizing the potential for holistic and transformational adoption of these new indigenous food crop opportunities for African agriculture. Is ‘political will’ the missing sixth capital for sustainable development?

Morphological and Chemical Diversity and Antioxidant Capacity of the Service Tree (Sorbus domestica L.) Fruits from Two Eco-Geographical Regions

Service tree, Sorbus domestica L., is a rare and neglected wild fruit tree species of southern and central Europe. Being distributed in different eco-geographical regions, with fragmented and low-density populations, S. domestica represents an interesting model case for investigating patterns of within- and between-population diversity at geographical and environmental scales. This study aimed to analyze the proximate composition, antioxidant activity, and morphometric fruit characteristics. We examined the diversity and population divergences of 49 S. domestica individuals originating from seven populations across continental and Mediterranean eco-geographical regions. In addition, tests of isolation by distance and environment were performed to detect the magnitude of divergence explained by geographic and environmental variables. Significant differences between the studied populations were found in almost all of the studied morphometric and chemical fruit characteristics. The studied service tree populations were characterized by high phenotypic variation despite the low number of trees per population. Model-based population structure analysis using morphometric and chemical fruit characteristics revealed three groups of service tree populations. We concluded that non-effective pollen and seed dispersal along with genetic drift and specific environmental factors resulted in a distinct phenotype with a specific chemical composition in the isolated island population. In addition, a pattern of isolation by the environment was revealed. We infer that morphological and chemical differences between the studied populations in the true service tree from different eco-geographical regions were mediated by adaptation to the specific environmental conditions.

Non-Timber Forest Products and the Cosmetic Industry: An Econometric Assessment of Contributions to Income in the Brazilian Amazon

This study explores Non-Timber Forest Products (NTFPs) production and company–community partnerships with the multinational cosmetic industry. The objectives are to critically assess: (1) how income generated from market-oriented NTFPs extraction impacts small farmers’ livelihoods; and (2) whether membership in cooperatives linked to such partnerships is a factor in improved livelihood. Household-level data from 282 surveys conducted in remote communities in four municipalities in the Northeast region of the State of Pará provide empirical insight into NTFPs extraction and processing activities by smallholder farmers in the Brazilian Amazon. We employ a spatial econometric approach to assess if engagement in NTFPs extraction and membership in cooperatives result in statistically significant increases in the overall household income. A series of spatial regression models are used, including Ordinary Least Squares (OLS), Spatial Autoregressive Regression (SAR), Spatial Error Model (SEM), Spatial Durbin Model (SDM) and their corresponding alternative Bayesian models. Our study finds that NTFP extraction and membership in cooperatives tied to company–community partnerships are statistically significant and result in increases in total income at the household level. Findings also show that distance to transportation modes and markets are statistically significant with more distant households earning greater income. This finding presents challenges for the long-term sustainability of green alternatives to development that rely on remote, inaccessible environments for the commodities of interest. This is especially pronounced given the commitment of the Amazonian Nations, and the massive national and international investments, in the Initiative for the Integration of Regional Infrastructure in South America (IIRSA), which has as its goal the creation of a multimodal transportation hub to integrate the continent with global markets and make accessible far reaches of the Amazon.

Ximenia americana: Economic Importance, Medicinal Value, and Current Status in Ethiopia

Ximenia americana is one of the most valuable wild edible plants in the world. In different countries, it is utilized as food, medicine, an essential oil source, and the industrial component to other products. In Ethiopia, it was one of the most known and very important plants for a long period of time. It was utilized as food, a medicinal plant, and animal feed. It was also one of the most economically important and culturally valuable plants. But nowadays, it is not adequately available in the country due to deforestation problem in the years. In addition, its economic importance, current status, and medicinal roles are not well documented and understood. As for research studies, it is concluded that unless a collective effort is taken, the existence of this plant is under severe threat and needs to have some measures. This review article is aimed at addressing the abovelined topics in detail and to pinpoint and explain the importance and status of Ximenia americana.

Rediscovering the Contributions of Forests and Trees to Transition Global Food Systems

The importance of forests to safeguard agricultural production through regulating ecosystem services such as clean water, soil protection, and climate regulation is well documented, yet the contributions of forests and trees to provide food for the nutritional needs of the increasing human population has not been fully realized. Plants, fungi, and animals harvested from forests have long provided multiple benefits—for nutrition, health, income, and cultural purposes. Across the globe, the main element of “forest management” has been industrial wood production. Sourcing food from forests has been not even an afterthought but a subordinate activity that just happens and is largely invisible in official statistics. For many people, forests ensure a secure supply of essential foods and vital nutrients. For others, foraging forests for food offers cultural, recreational, and diversified culinary benefits. Increasingly, these products are perceived by consumers as being more “natural” and healthier than food from agricultural production. Forest-and wild-sourced products increasingly are being used as key ingredients in multiple billion dollar industries due to rising demand for “natural” food production. Consumer trends demonstrate growing interests in forest food gathering that involves biological processes and new forms of culturally embedded interactions with the natural world. Further, intensifying calls to “re-orient” agricultural production provides opportunities to expand the roles of forests in food production; to reset food systems by integrating forests and trees. We use examples of various plants, such as baobab, to explore ways forests and trees provide for food security and nutrition and illustrate elements of a framework to encourage integration of forests and trees. Forests and trees provide innovative opportunities and technological and logistical challenges to expand food systems and transition to a bioeconomy. This shift is essential to meet the expanding demand for secure and nutritious food, while conserving forest biodiversity.

Preparation and Characterization of Cinnamomum Essential Oil–Chitosan Nanocomposites: Physical, Structural, and Antioxidant Activities

In this study, different amounts of cinnamomum essential oil (CEO) were encapsulated in chitosan nanoparticles (NPs) (CS-NPs) through oil-in-water emulsification and ionic gelation. An ultraviolet-visible spectrophotometer, Fourier-transform infrared spectroscopy, synchronous thermal analysis, and X-ray diffraction were employed to analyze the CEO encapsulation. As observed by field-emission scanning electron microscopy, NP size analysis and zeta potential, the prepared CS-NPs, containing CEO (CS-CEO), were spherical with uniformly distributed sizes (diameters: 190–340 nm). The ranges of encapsulation efficiency (EE) and loading capacity (LC) were 4.6–32.9% and 0.9–10.4%, with variations in the starting weight ratio of CEO to CS from 0.11 to 0.53 (w/w). It was also found that the antioxidant activity of the CS-NPs loaded with CEO increased as the EE increased. The active ingredients of the CEO were prevented from being volatilized, significantly improving the chemical stability. The antioxidant activity of CS-CEO was higher than that of the free CEO. These results indicate the promising potential of CS-CEO as an antioxidant for food processing, and packaging applications.

Urban foraging: Land management policy, perspectives, and potential

Gathering of uncultivated food from green spaces, also known as foraging, is observed in urban areas across the world, but the literature focuses predominantly on the global north. Our study examines the existing urban land management structure and its approach to urban foraging in the eastern coastal region of South Africa. Through interviews with municipal officials in nine cities, we identified different stakeholders and their roles in urban green space management. We then used network analysis to represent interactions and influence of these stakeholders, and environmental worldviews to determine organisational and perceptual barriers to and enablers of foraging in urban green spaces. The policy on urban green space management, as well as land managers themselves are amenable to the concept of foraging in public spaces. Lack of knowledge on wild indigenous species and sustainable offtake, ambiguous, coarse, or lacking policy, and normative views of pristine nature may hinder foraging. We recommend pathways for policy and stakeholder partnerships to incorporate sustainable foraging in their biodiversity conservation and land stewardship strategies.

Ethnobotanical Survey of Wild Edible Fruit Tree Species in Lowland Areas of Ethiopia

This study aimed to provide baseline information about wild edible tree species (WETs) through surveying of different ethnic groups in dryland areas in Ethiopia. Here the data about WETs are scant, and WETs status is unexplained under the rampant habitat degradation. Use forms, plant parts used, status, ethnobotanical knowledge, conservation needs as well as those threats affecting WETs were reviewed. The study identified 88 indigenous wild edible plants, of which 52 species were WETs. In most cases, fruits were found as the dominant use part, and they were used as raw but were occasionally cooked and preserved. Roots and bark uses are also reported from Ximenia americana and Racosperma melanoxylon respectively. June, July and August were critical periods observed for food shortage in most of the regions. However, in the Gambella region, food shortages occurred in most months of the year. The respondents in this region suggested that WETs could potentially provide them with enough food to make up for the shortage of food from conventional agricultural crops. From the respondents’ perception, Opuntia ficus-indica, Carissa edulis and Ficus vasta were among the most difficult to locate species, and they also received the highest conservation attention. Because of the variety of WETs and existing different threats, a management strategy is required for future conservation, as WETs are vital for the livelihood of local communities and are also necessary to devise a food security strategy for Ethiopia. The lesson obtained could also be useful in other dryland parts in developing countries with similar contexts.
