Gum and Resin Production and Marketing: Implications for Pastoral Livelihood in Adadle District, Somali Region, Ethiopia

. Both locally and nationally, Ethiopia’s gum resin sector has a substantial economic impact. Even though collecting and selling gum and resin is one of the main livelihood activities in Ethiopia’s remote pastoral areas, there are few case studies that adequately refect national realities. Terefore, the goal of this study is to pinpoint and evaluate gum and resin production and sale, as well as any implications for pastoral livelihood, in the Adadle district of the Somali Region. Both purposive and random sampling techniques were employed. Te primary data gathering technique used were household surveys, key informant interviews, focus groups, market surveys, direct observation, and surveys of community-based organizations. Multiple response tests, one-way ANOVA, and descriptive statistics were used in SPSS Version 26 to statistically analyze the collected data. Te study discovered many Acacia , Boswellia , and Commiphora tree species that are employed in the production of gum and resin. It was also found that natural oozing and artifcial tapping were the methods used for collecting and harvesting gum and resin. Te average amount of gum and resin/frankincense harvested annually by each family was 219.82kg and 58.27kg, respectively, with gum harvesting being substantially higher ( p 0 . 05) than resin harvesting. Te recurrent drought, season, and awareness level of harvesters on taping were the factors afecting the quantity and quality of production. Te average annual household income from gum and resin/ frankincense was 18,684 Ethiopian Birr and 43,704 Ethiopian Birr, respectively. Te mean annual income from resin was substantially larger ( p 0 . 05) than that of gum. Te gum and resin market chain in the area comprises eight actors with fve market channels. Te research also demonstrates that the income made by selling gum and resin was used to pay for basic necessities for the family, save money for health care and medications, and pay for social concerns and educational expenses. Recurrent drought, lack of market access and market expertise, lack of institutional cooperatives, and lack of infrastructure and facilities were all determined to be obstacles to the production and sale of gum and resin. Generally, resources should be conserved and interventions should be done to ensure the sustainability of the resource base and improve production potential. Proper tapping techniques should be introduced to enhance production potential, and access to market information should be ensured to maximize primary producers’ income share insured for maximizing the income share of primary producers.


Introduction
In the Horn of Africa, it has long been customary to use tree resin and gum for various purposes [1]. Dry forests and woods in sub-Saharan Africa are fragile, yet they nonetheless have a variety of ecological and economic advantages to humanity because of the region's abundant biodiversity [2]. Several sub-Saharan African countries employ a variety of species to produce gum and resin products, and the drylands of East Africa are particularly well known for their potential and long history of extraction and commercialization of natural gum and resin products [3]. When considering the resource potential of gum and resins, it greatly outpaces global output, and Sudan also produces a signifcant amount of gum arabic, more than 80% of the world's total production [4]. Gum arabic had an annual export potential of 100,000 tons from African nations up until 2017, and its demand was anticipated to reach 150,000 tons yearly by 2020 [4]. Ethiopia contributes just 0.9% to the global market, whereas nations like Chad, Nigeria, and Sudan make up over 97% of it. Around 7,000 tons of karaya gum from Sterculia setigera Del. are needed worldwide, and Senegal is the top exporter in Africa [5]. Ethiopia, Kenya, Somalia, and Eritrea are the principal exporters of 3,000, 2,361, 1,200, and 400 tons of aromatic resins [3].
Natural shrub and tree species that produce gum and resin are well recognized, and they are most frequently found in the drylands of Ethiopia [3]. Tis is because nearly all dryland settings are home to species that contribute signifcantly to the land mass through the production of gum and resin [6]. Current estimates of the area of well-stocked dry forests and woodlands for the production of gum and gum resins in Ethiopia vary from 28,550 km 2 to 43,350 km 2 [7]. Potential producers of commercial gum and gum resins include species like Acacia and Commiphora. In particular, Myrrha and Opopanax were derived from the Commiphora species, frankincense from several Boswellia species, and gum arabic from Acacia species ( [3,7]).
Particularly in the drylands of East Africa, the extraction and commercialization of natural gum and resin products are noted for their potential and lengthy history [3]. For 60% of rural residents who are classifed as poor, the dry woods serve as a signifcant resource base for economic growth and livelihoods. To fulfll their basic needs, some 320 million people rely on products from dry forests [8]. Non-timber forest products other than timber provide 20-60% of the overall family income and are reported as a contribution even surpassing agricultural activity [9] and also serving as a complementary income to other livelihoods [10]. Te gum and resin industry contributes signifcantly to the nation's economy both locally and nationally [11]. Forest harvesting is a traditional source of income and sustenance for rural families [12]. Gums and resins support local lives by providing both fnancial fow from selling goods to customers and subsistence value [7]. Plant resins are regarded for their use in the creation of adhesives, varnishes, and food glazing agents as well as their worth as raw material for the production of other chemical compounds and as scent-and incense-related substances. Plant resin was utilized for the frst time in Southern Africa during the late Middle Stone Age as an adhesive for hafting stone tools [13]. Te abundance of tree species in Ethiopia's dry forests, which provide the gums and resins that are the most valuable export products from the country's forestry industry, is a signifcant characteristic of those areas [7].
Despite the high potential of the resource base, Ethiopia now produces and exports very little gum arabic each year [8]. Tis is a result of inadequate output, acceptable tapping methods, a lack of infrastructure facilities, appropriate institutions, a dearth of cooperatives, and challenges in gaining access to markets, market knowledge, and reasonable market prices [14]. Additionally, there are gaps in or limitations in knowledge regarding the production and gum quality from diferent tree sources, the ideal age trees for tapping, establishment techniques, silvicultural management, and phenological record needs of the species [15]. Inconsistent marketing volumes over time and limited production range, lacking in a marketing structure, and institutional shortcomings decline benefts required from gums and resin production [7]. Te main reason for the decline in production volume and potential is a low gain of producers from gum and resin due to very low prices for their products [16]. Due to a lack of producer organization in cooperatives, the percentage of producers' portion in the marketing margin decreases [16]. Institutions (government and nongovernment) can support extension services and support the development of a supply chain that might increase the amount of money the working poor can earn. Tis could only be accomplished by developing and improving pertinent mechanisms for the resource management and usage that is sustainable for gum and resin [17].
In Ethiopia's rural regions, gathering and selling gum and resin is a substantial source of revenue; however, few case studies have been conducted. Gum and resin resources have the potential to support rural development in general and climate change adaptation in vulnerable pastoral, agropastoral, and farming communities, in particular, but this potential has not yet been fully exploited at the national level [18,19]. Concerning the study area, information on the state of the resources for woody plants that produce gum and resin, production systems, and marketing strategies has not been studied. Studies on the livelihood implications of gum and resin production are also either scanty or completely lacking. Terefore, this study analyzes the gum and resin production system, assesses the gum and resin marketing strategies, and establishes the gum and resin marketing implications in order to ascertain the livelihood consequences of gum and resin production and marketing in the study area.

Description of Study Area.
Tis research was carried out in Ethiopia's Somali Region's Adadle district, Shabelle Zone ( Figure 1). It is one of the nine districts in the Shabelle Zone, which is located 600 and 1228 kilometers from Addis Ababa city and Jigjiga town, respectively. Adadle may be found in the lowlands of the

Research Design.
Tis section provides a summary of the study's research methodology, including the primary datasets used, their sources, kinds, and data analyzing techniques. Cross-sectional reconnaissance/preliminary survey was used to design the methodology and sampling techniques for the study. Te production and marketing of gum and resin, as well as their efects on pastoral life, were identifed using purposive random sampling procedures, which incorporated qualitative and quantitative data. Field observations, focus groups, key informant interviews, and tree identifcation collection were also used to generate and explore in-depth information, and feld observation and tree identifcation collection also were used.

Sampling Techniques and Sample Size Determination.
Purposive and stratifed random sampling techniques were employed for the selection of study districts, kebele (smallest administrative unit), and respondents. Terefore, a reconnaissance survey was conducted in the study area before data collection. According to the results of the reconnaissance survey, the Adadle district was purposefully chosen based on its potential for producing and marketing resin and gum [14]. Secondly, the total kebele in the district was stratifed into two rural and urban strata. Following this, six rural kebeles, Haben, Alihuley, Kulmil, Dabagali, Toxopo, and Elbied, were intentionally selected because they depended on the collection and sale of gum resin. Te total household was stratifed into two strata as participants and non-participants in the production and sale of resin and gum. Following this, 1,524 households who have been involved in the production and selling of gum and resin were identifed from six kebeles, and 150 respondents were selected randomly through the lottery method by taking 25 households from each kebele.

Data Collection and Species
Identifcation. Te feld observations, focus groups, meetings with key informants, respondent surveys, and identifcation of tree species by guided feld walk with informants and market surveys were the main techniques applied. In general, data gathering involved a sequential exploratory technique [21] in which qualitative data were added to quantitative data collecting and analysis [22]. As a result, respondent interviews (surveys) were conducted, and data regarding the varieties of gum and resin were obtained; the species from which they are tapped, the collection techniques, and other topics were acquired using a semi-structured questionnaire. Additionally, it is utilized to collect information on the collecting period, the expected yearly revenue from the sale of gum and resin, the proportion of money used for sustaining households, local or domestic applications, therapeutic benefts, and other signifcant socioeconomic data. In addition to this, detailed information was explored through detailed conversations and discussions with key informants (KIs) and focus group discussions (FGDs). KIs were selected through the snowball method [23], mostly local people who had lived a long time in the locality and who have frst-hand knowledge and know very well the history of the area. Participants in FGDs were 6-8 individuals who included kebele administrators, youth, women, and elders living in these gum and resin hotspot areas.
Guided feld walks and observations were also done in the production and marketing areas. It was utilized to triangulate the information gathered from other sources and identify and catalog the main tree species in the research area International Journal of Forestry Research that are used to produce gum and resin. Scientifc names of the plants recorded were identifed by using taxonomic keys, the fora of Ethiopia and Eritrea [24]. Finally, the market survey was undertaken to record the types and names of gum and resins supplied to the market preference for diferent types and other aspects of gum and resin sold in the local markets in the study area. Terefore, semi-structured interviews were conducted with gum and resin sellers and buyers and local cooperatives engaged in gum and resin collection and marketing based on a semi-structured questionnaire checklist following methods used in [18,25]. For further information, discussions were held with the district administrators and experts and trade and industry ofces of the Adadle district to have basic information for analyzing its value chain.

Data Analyses.
Data were processed, stored, organized, checked, and categorized into quantitative and qualitative categories, encoded into Excel sheets, and transferred to the SPSS program. SPSS Version 22 was used to statistically evaluate quantitative data. Several statistical studies using one-way ANOVA were conducted to investigate the function that gums and resins play in rural livelihoods. Descriptive statistics were employed to describe the various variables. Text analyses were used to analyze qualitative data through the way of condensing and summarizing qualitative information.

Gum and Resin-Producing Tree Species.
Several gum and resin-bearing tree species identifed in the study area were Acacia oerfota, Acacia stuhlmannii, Boswellia frereana, Boswellia neglecta, Boswellia ogadensis, Commiphora erythraea, Commiphora guidotti, Commiphora myrrha, and Commiphora ogadensis which are the most commonly known gum and resin trees species in the study area (Table 1). According to the response from the respondent, two Acacia species, Acacia oerfota and Acacia stuhlmannii, were used for the production of gum. Tese tree species are characterized by their drought-tolerance potential, and most of them are small-leaved trees and shrubs.

Methods of Collecting and
Harvesting. Gum and resin products are produced or harvested via both artifcial tapping and natural oozing. Based on the response of respondents, 48.0% and 16.0% of respondents prefer and use natural oozing and tapping for the harvesting of products, respectively ( Figure 2), whereas 36.0% of respondents revealed that they prefer and use both natural oozing and artifcial tapping for harvesting gum and resin. Harvesting through natural oozing is undertaken by gathering the naturally oozed substance from the tree's trunk and branches and dropped/failed gum and resin products below the canopy of the trees. Artifcial tapping was done by specially designed axes and other metal tools. After tapping, they wait for a week to collect the gum and resin from the tapped tree.
Responses of respondents revealed that most of the time natural oozing was mainly used for the collection of resin as it is used for the collection of products from natural exudates. Artifcial taping is revealed as it is not used for the collection of resin because it afects the quality of the resin products. Tis is because during taping there is a wounding tree and there is the mixing of other compound exudates due to the tree wound and these compounds may mix and afect the quality of the resin. Regarding this, respondents show that the loss of quality due to mixing with other products afects the market value as buyers in the cooperative throw out resin products mixed with other compounds during the sorting process in the market area. Because of this, they only use natural oozing for the collection of resin to keep the quality of products. But in contrast to this, Getahun and Kebede [26] found that tapping enhances the quality of resins.
Te process of artifcially injuring tree stems and branches to produce gums is known as tapping, according to responses, which brings oozing of exudates through the openings of wounds. Tey revealed that they use only taping for the production of gum in addition to natural oozing because they believe that even if there is a quality decline of products, the taping has the potential to increase the amount of gum collected per day. Key informants and participants in the focus group discussion revealed that after tapping the tree, they left it for 4-6 days to get back to collect products. In line with this, the authors of [27,28] found that tapped trees yielded more yield than untapped trees, and tapping improved the productivity of gum arabic by 77.42% when compared to natural oozing.

Gum and Resin
Harvesting. Te mean daily, monthly, and annual harvesting of gum and resin in kilos by household and the daily average harvesting of each individual were calculated. To do this, the number of families engaged in harvesting, the number of days per month allocated for gum and resin collection, and active harvesting months/seasons were considered. Following this, two individuals from each household on average were considered engaged for 15 days in each month and 6 months which are active collection times in the year. Based on this, the overall mean daily harvesting of gum was (1.22 ± 0.30) and (2.44 ± 0.60) kilograms by individual and household, respectively. As a result of this, the mean monthly and annual harvesting of gum was (36.64 ± 8.99) and (219.82 ± 53.95) kilograms per household, respectively ( Table 2). Te amount of gum being harvested was signifcantly more (p 0.05) than that of resin when compared with it, with a 5% confdence interval ( Table 2). Tis means the mean monthly and annual harvesting of resin was only (9.71 ± 3.00) and (58.27 ± 17.98) kg per household, respectively (Table 2).
Te amount of gum and resin collected varied more, with the average annual collection of gum being three times greater than the average annual collection of resin (Table 2). Regarding this, respondents revealed that the diference was mainly due to the availability of products; the density of trees and the method of the collection were the major factors that contributed to the harvesting of both products. Te frst reason is that the more abundant tree species in the area were gum-producing (Table 1). Te other reason is that from the two methods identifed (Figure 2), as used for production and collecting gum and resin, gum was collected through both artifcial tapping and natural oozing, and in them, tapping was commonly used. Respondents revealed that artifcial taping has the potential to increase the amount of gum to be collected, whereas resin was collected only through naturally oozing exudate substances on the stem and branches of trees and sometimes from the ground below the canopy of trees. In addition to this, natural exudate products need time and season of production, and collectors and harvesters wait for the readiness of products and the time of collection. Tese factors reduce the amount of resin to be collected than gum.

Factors Afecting the Quality and Quantity of Gum and
Resin. Te respondents identifed a number of elements that adversely afect the quantity and quality of gum and resin products. From these, recurrent drought, the season of production, post-harvest handling, lack of awareness of taping and collection methods, the topographical situation of the area, and contaminants were factors afecting both the quality and quantity of products ( Figure 3).
Dry seasons, mostly from October to March, are the best times for production and harvesting, while wet seasons are not advised because they degrade the quality of the goods. Similarly, the quantity and quality of gum and resin products were found to be much higher during the dry season because it makes the tapping and collection procedure simple, according to research in [29] which also indicated that seasonal variation afects production and quality of these products. Because the recurrent drought afects the regenerative potential of trees, drought was revealed as one of the major factors which afect the quantity of product. According to the respondents, if there was no drought, trees would start to regrow and replenish the injured parts formed through tapping production and they grow both physiologically and morphologically and build up their production potential during the normal rainy season. But recurrent drought afecting both the physiological and morphological growth of trees leads to less quantity production. Tis is in agreement with Berhanu et al. [30] who discovered that harvesting and production are seasonal, taking place during the dry season, and that refueling and wounding last until the start of the wet season.
Respondents and cooperative members in the market area revealed that post-harvesting handling of gum and resin was also a factor that afects the quality of products. Tis is because the majority of collectors were herders and shepherds who did not have enough know-how to store products after harvesting. In addition to this, during harvesting, they have no proper materials to collect and they use what they fnd on the roads and production areas including old plastic bags and clothes. Tis shortage of awareness always afects the quality of products, mostly resin, because it is collected with much moisture and has the potential to retain dust and other substances. Similar to this, fnding from [30] confrms that most collectors were cattle herders, they have no training in methods, and they developed experience from their parents. Respondents also show that as a producer, the   topography is also a factor afecting the quantity of gum and resin. Tis is because the gum and resin-bearing tree species prefer to grow on fat land than in hilly areas and trees grown on fat land have more potential for the production of gum and resin.

Gum and Resin Market Chain Actors.
Te study revealed that the gum and resin market chain comprises eight diferent actors playing their own roles in the marketing chain in each stage from production/harvesting to diferent consumers (Table 3). Responses gained from collectors, personnel in the cooperative and agents, and feld observations show that gum and resin producers/harvesters are pastoralists who produce and/or harvest gum and resin for production. Te local village traders are pastoralists who have small capital and are engaged in buying a product from producers and/or collectors. A cooperative is a system created by persons in the Adadle district who collect and buy gum and resin from collectors and local village traders and transport and sell a product to agents in Gode city and exporters from Somaliland. Tey have permission from the government in the district and pay taxes to the government every year. Agents were engaged in collection, cleaning, sorting, weighing, and buying from village traders and cooperatives, tax-paying to the government and transporting to Jigjiga and Harar city, and selling to retailers and exporters. In this stage, there are two actors, daily laborers and sometimes intermediaries. Daily laborers engaged actors by doing activities such as cleaning, sorting, and repacking in the hands of agents and loading gum and resin to a truck for transportation. In line to this fnding, study of [16] shows that daily laborers are involved in the loading and unloading and sorting, cleaning, and grading work for agents. Sometimes when new retailers and exporters come to agents and cooperatives for buying products, intermediaries serve through mediating and creating agreements between agents and new retailers and exporters on the price and collecting information about the price on local market and other market situations. Retailers were small traders who performed their business independently in shops and commodity trading areas in the market by selling it to the fnal consumer through retail. Te fnal consumers in the marketing chain actors were the end of the value chain and fnal product consumer types. Tese are households, churches, and sometimes factories in the national market, and from them, factories and industries use goods from the international markets while families and churches are customers in the local and national marketplaces.

Market Channels and Marketing Chain Mapping.
Gum and resin goods are moved along the marketing chain from manufacturers and/or collectors to ultimate customers with the assistance of the value chain actors mentioned in Table 3. By combining the responses from respondents and observations from the district, fve main gum and resin market channels were developed based on the actors in the market chain and shown on market chain mapping ( Figure 4).

Channel
≥ producers and/or collectors ⟶ cooperative ⟶ agents ⟶ retailors ⟶ consumers Channel 2 ≥ producers and/or collectors ⟶ cooperative ⟶ exporters ⟶ retailors ⟶ consumers Channel 3 ≥ producer and/or collectors ⟶ village trader ⟶ cooperatives ⟶ Agents ⟶ retailors ⟶ consumers    In channel one, producers and/or collectors collect the product from the production area and sell products to organized cooperatives. Cooperatives in this channel buy products from the producers and collectors, then keep products in their store in the district and sell them to agents in Gode city. Following this, agents in Gode city sell their products to retailers that come from Jigjiga and Harar city, and the retailers sell them to fnal consumers. In this channel, the market chain is fnalized on a national basis. But in channel two, the cooperative in this channel sells products to exporters from Somaliland. Following this, exporters sell it to retailers and/or fnal consumers. In this channel, the market chain is fnalized in international marketing.
Finally, in channel fve, organized cooperatives sell products directly to the exporters. In channels four and fve, there is international marketing of cooperatives in the district and agents sell products to the exporters who come from Somaliland. Te majority of the time, organized cooperatives and agents keep products in storage for a while since doing so gives them a higher opportunity of maximizing their proft.

Value Distribution and Value Addition Systems of Gum and Resin.
According to the response of respondents and cooperatives from the Adadle district, collectors sell one kilogram of gum and resin to an average of 85 and 750 Ethiopian birrs, respectively. In addition to this, members of the cooperative and agents in the district and Gode city exposed that there are also costs related to sorting, cleaning, repacking, loading, tax payments, and transportation and storage sites. Based on this, the distribution of gum and resin in the district is done by taking only one national marketing channel which is from the Adadle district to Harar city. For this case, the average annual harvesting per household which is 219.82 kg gum and 58.27 kg resin ( A preliminary marketing margin analysis for the shorter marketing channel from Adadle to Harar was done, and the diferent gums and resins exhibit variations in market price and marketing margins for diferent actors in the value chain. Te value distribution shows that the percentage share of producers in the fnal price was 21.25% and 50% for gum and resin, respectively (Table 5). Tis indicates that the percentage share of the fnal price of resin was higher than  International Journal of Forestry Research that of gum. For the value chain actors of gum, the retailers have a greater share of the fnal price, and producers, cooperatives, and whole sellers have fewer shares in gum value distribution. Te results indicated that producers did not necessarily beneft from harvesting and selling gum. Similarly, cooperative bodies in the district have only 5.91% of the fnal price share. Tis indicates that the share of producers and cooperatives in the fnal price of gum tended to be lower than that of wholesalers. Tis is because they have no market information and the values are only decided by retailers and depend on the agreement of the whole sellers who buy products from them. Less number of cooperatives in the area and a lack of cooperation with producers afect the number of their share benefts from the total margin. Tis is in line with Kassa et al. [31] who found that particularly long marketing channels and a lack of organization of producers and cooperatives afect the percentage share of producers. Regarding these, Te Velde et al. [32] also indicated that better association among producers and more organized value chain governance could result in more organized production and higher profts for value chain participants upstream. Te study found that there is no value addition process for harvesting and collecting gum and resin in the hands of pastoralists as their families engaged in collecting and harvesting without any cost or product process. Te value addition system of gum and resin was started at the hands of a cooperative in the district through the process of sorting, weighing, and buying a product from collectors and harvesters because of the costs pained for sorting and weighing. Te value related to transporting products from Adadle district to Gode city was also the value added to the hands of cooperatives in the district. Te agents who buy products from cooperatives undertake diferent additional work. Tese are the cost of buying a product from a cooperative, cleaning, sorting, repacking, and loading gum on a truck and the cost of transportation. In addition to these, costs sometimes were related to the intermediary in mediating and creating an agreement with agents who serve as value chain governance, and the value relationships to the selling of products for retailers and exporters and consumers were the diferent values added in the marketing of gum and resin in the study area.

SWOT Analysis for Harvesting and Marketing of Gum and Resin.
A SWOT analysis was done to identify internal and external factors that might afect gum and resin production and market practice in the study area (Table 6).

Income from Gum and Resin
Production. Based on the local market practice of both gum and resin, the total daily average income earned per individual and mean daily, monthly, and annual income per household were identifed and expressed in Ethiopian birr. Based on this, the average prices of both gum and resin were 85 and 750 Ethiopian birr/ kg, respectively. Based on these, the mean monthly and annual income of (3114.06 ± 764.36) and (18684.36 ± 4586.16) Ethiopian birr was gained from gum per household, respectively, whereas (7,284.0 ± 2,248.12) and (43,704.00 ± 13,488.71) were gained from resin per household, respectively (Table 4). Tese show that the income earned from selling resin was signifcantly higher (p < 0.05) than that of gum.
Tis study found that the average annual income from gum and resin was 18, 684.36 Ethiopian birr (357.53 USD) and 43704 Ethiopian birr (836.28 USD), respectively. Te result supports the idea that many pastoral households are highly dependent upon income from gum and resin for their livelihoods. Respondents and KIs demonstrate that these sales and production diversify economic activities and lessen the hazards associated with recurrent droughts, such as livestock losses owing to feed and water shortages. KIs and participants in FGDs revealed that during the drought years of 2015 and 2016, pastoralists took advantage of the collecting and marketing of gum and resin. Tis provides cash income which is complementary to other kinds of income, acting as a fnancial safety net during times of drought and as part of a drought adaptation strategy. In line with this fnding, Berhanu et al. [30] discovered that the current methods of production in pastoral communities make frankincense a key source of revenue, diversify the economic activities, and lower the dangers connected with drought.

Livelihood Role of Income Earned from Gum and Resin.
Money earned from the selling of resin and gum is allocated to diferent uses and expenses for livelihood. According to the response of 98% of respondents, more of the income was allocated to fulflling family basic needs such as purchasing food, buying clothes, and construction and maintenance of houses for shelter. 79% of the respondents revealed that the income generated was also assigned to buying additional livestock and purchasing supplementary feed for them. Te other remaining amount of income was also expensed with medicine and health care, saving for other unexpected events, social, cultural, and religious events, and school expenses (Table 7).    During the drought, gum and resin functioned as a safety net because the cost-related livelihood of pastoralists was mainly fulflled from the income obtained. Key informants show that the income generated from selling gum and resin supports families during recurrent drought times. Additionally, it is crucial for pastoralists who lost their livestock during drought time because some pastoralists who lost their livestock due to drought hazards increased their postdrought livestock numbers and assets. Terefore, it serves as a mitigation and adaptation strategy for climate change.
In line with this study, Hido and Alemayehu [14] found that the primary source of income for the pastoral community was the collection and sale of gum and resin products, which also contributed signifcantly to the food purchases of households. Te cost of health care and medication for humans and livestock, savings, school expenses, and costs related to participating in diferent social-cultural issues were covered by the income earned from selling gum and resin products. In line with this, Worku et al. [19] reported the only source of revenue for women and schoolchildren, and the third most signifcant source of subsistence after crop and honey production was income from the manufacturing of gum and resin [29].

Challenges and Constraints on the Production and
Marketing of Gum and Resin. Te production and marketing of gum and resin in the study area are not free to access and not without challenges; there are diferent societal, institutional, and environmental (ecological) challenges and constraints. Regarding this, respondents reported that recurrent drought, lack of access to market and market information, lack of institutional cooperatives, shortage of infrastructure and facilities, inadequate tapping knowledge and techniques, and diferent anthropogenic activities are challenges that constrained the proper production and marketing of gum and resin in the study area ( Figure 5).
Te study found that drought and shortage of rainfall due to climate change and variability were the major factors that threatened the gum and resin-bearing tree species because the seasonal growth of the plants was afected due to a shortage of rainfall and extreme temperatures ( Figure 5 and Table 6). Drought also afects the regeneration of tree species in the grazing land and is going to afect the sustainability of tree species. Te feld observation also shows that only large trees were available in the area and overgrazing was due to a shortage of livestock forage and feed. Tis is because recurrent drought causes the loss of palatable and browser species and it diverts browsers' livestock to rely on gum and resin-bearing trees and becomes a threatening factor for some browsing gum and resin trees. Funding was agreed with the study of [33,34] found that recurrent droughts and related overgrazing greatly afected gum production and cause the death of many gum-resin tree species and causes ecological disturbance and overgrazing has a deleterious efect on the natural regeneration of plants that produce resin.
Lack of access to market and market information and shortage of competitive market areas for selling collected products were the major constraints for the production and marketing of gum and resin ( Figure 5 and Table 6). Tis is because producers have no clear and enough market access and market information and the only cooperative body in the district is in operation to collect and buy products from collectors. Regarding this, respondents exposed that they had no interference in the buying and selling process and prices were solely decided by cooperatives in the district. According to key informants, the lack of another competitive cooperative body to buy the product from producers afects the freedom to decide on the price and negotiate with buyers on the prices. In this case, respondents show that if there was more than one cooperative engaged in buying products in the district, we may have the freedom to decide on the price and come into agreement on the value and to have decisions on prices.
Te other anthropogenic factors were also major human-induced factors that threatened the sustainability of these valuable tree species ( Figure 5 and Table 6). Responses from KIs and participants in FGDs revealed that cutting trees for the construction of fences around the home was the major anthropogenic efect or the threat to gum and resin trees. Tis is because some tree species such as Boswellia frereana and Commiphora myrrha have potential to propagate vegetatively and pastoralists cut and construct life defenses around and in front of their homes from such trees. Similarly, Lemenih and Kassa [7] found that humanrelated disturbances such as overgrazing, forest fre, and intensive removal of trees for lumber for building and fuel have a major negative infuence on gum-resin tree species. A lot of damage to some of the resources through poor and excessive tapping due to inadequate tapping knowledge and techniques was also another challenge to tree resources. It not only afects the quality of the product but also afects the sustainability of tree species. Respondents demonstrate that continuously taping a single tree, cutting and injuring trees, disposing of trees to insects, infecting trees, and killing trees during extended drought times all have a signifcant negative impact on tree development. Similarly, the study in [30] found that the attempt to improve yield through negligent tapping and frequent, strong wounding was shown to be damaging to the trees. Deeper wounds during the dry season caused longer healing times, which led to tree death since poor growth circumstances prevented speedy recovery. Te sum of frequency and percentage are more than N and 100%, respectively, because of multiple response test analysis.

Conclusion and Recommendations
In Ethiopia's rural areas, particularly in the drylands, one of the main livelihood activities is the collecting and selling of gum and resin. In this study, the gum and resin manufacturing system, gum and resin marketing tactics, and the impact of gum and resin production and marketing on local residents' livelihoods are all identifed. Te study found that products from gum and resin were collected and harvested through natural oozing and artifcial tapping. Te mean annual harvested gum was signifcantly higher than the mean annual harvested/ collected resin. Te gum and resin market chain comprises eight actors with fve market channels. Even though the average yearly harvest of gum was larger, the average annual income from resin was much more than the average annual income from gum. Te income gained from gum and resin was allocated to fulflling family basic needs, medicine and health care saving, and social issues and school expenses. Te problems and limitations to the production and sale of gum and resin were recurrent drought, lack of market access and market intelligence, and lack of institutional cooperatives, infrastructure, and facilities. Te research comes to the conclusion that the production and commercialization of gum and resin signifcantly improve household livelihood and act as risk avoidance, adaptation, and mitigation strategies for climate change variability such unpredictable rainfall and drought. Finally, the study suggests that local governmental bodies and local communities also should work jointly to ensure the sustainability of species of gum and resin-producing trees. Timely delivery of market information should be ensured and market access, infrastructure, and availability of enough institutional cooperatives should also be improved. Awareness should be created through short-and long-term training for producers and cooperative members. It is advised that the marketing chain and resource access be properly governed.
