Abstract

Rehabilitating the degraded rangeland in Ethiopia is very crucial issue for improving the livelihood of pastoralist life style and the environmental sustainability of the country. In Yabello rangeland area, the local communities used enclosure method in order to rehabilitate the degraded rangeland area and try to address their livelihood problems. In general, the current study tried to assess the benefits obtained from the rehabilitated rangeland area from the three-study site chosen through purposively techniques based on the information gathered from different aspect. Semi- structured interview, Focal group discussion has held with key informants and different stakeholders at each kebele levels have conducted to gather information from the 150 respondents (50 from each kebele) and analyzed both in qualitative and quantitative approaches. The result showed that the rehabilitated rangeland area mainly used to get both numerical and non-numerical benefits like livestock fattening, grazing purpose, woodcutting and charcoal production and among this livestock, fatting is the major source of income across the whole study site and Dida Tuyura (A1) is the most productive site among the rest. From this, we recommend that there is a need to enhance market linkages for restored rangeland products that would then drive the adoption of rangeland restoration initiatives and those helps for sustainable utilization of the rehabilitated.

Introduction

Rangeland degradation in the semi-air rangeland of Yabello is a well-known and challenging problem for pastoralists [1]. Both climatic and anthropogenic factors are the major rangeland degradation process simultaneously takes away the capacity of the land to provide regulating, socio-cultural and supporting services [2]. A few decades ago, the Yabello rangelands in southern Ethiopia have considered amongst the best grazing lands in east Africa [3]. Because of the global climate change and the intensive human activities, desertification / land degradation has become the most serious problem in the modern society, particularly in the ecologically sensitive arid and semi-arid areas. Rangeland degradation implies a reduction in rank or status, which includes a loss of topsoil, a change to a simple floral/ fauna composition or a transition from one organic form to a lower organic form, and continuous reduction of productivity/biomass of the ecosystem [4]. Once rangeland has been degraded, it is often possible to rehabilitate it and thus restore it to a level of utility, possibly not as its original state, but better than it was in its damaged state [5]. Rangeland degradation is the most extensive types of current land use problems mainly in Yabello area. Overgrazing by livestock is the principal land problem in the arid and semi-arid regions, coupled with land use change to cultivated farmland in the many countries including Ethiopia [4]. Changes in natural vegetation dominated by the grass layer, leading to dominance of woody cover and increase in unpalatable forbs, which considered as a threat to range conditions in Yabello [5]. Restoration of land degradation is essential to ensure long-term productivity of semiarid rangeland of Yabello. For improving pasture, quantity and quality where graminoid and nongraminoid herbaceous plant species have disappeared. It have been limited to destocking, bush management, and intermittent grazing and its basic objective is to encourage palatable, productive perennials, as they are good for animal performance and to maintain a healthy environment [3,6]. Other methods such as ripping and grass reseeding have the potential to restore degraded rangelands and improve their potential for livestock production [7]. The Yabello pastoralists traditionally practiced strategic grazing management to avoid local overstocking around the scarce dry season water sources. The different measures taken were cultivation of land, sharecropping, formal employment in mechanized farms and other organizations, casual labor and small trade. As documented by Solomon [8], most of these pastoralists for risk management strategies utilized strategies when sole dependency on livestock is in question. Understanding the socio-economic impacts of rangeland rehabilitation is essential to the management and planning of similar initiatives. Therefore, this study aimed to quantify the benefits derived from the rehabilitated semi-arid rangeland in Yabello area, Southern Ethiopia.

Materials and Methods

Description of the study area

The study made at Dida Tuyura, Danbal-Waccu and Arero kebele of Yabello district Borana zone, southern Ethiopia in 2018. It is situated at 566 km south of Addis Ababa along Addis – Moyale road. The area of Yabello town is 5426 km2, and located between 4°30′55.81″and 5°24′36.39″ north latitude and between 7°44′14.70″and 38°36′05.35″ east longitude, the altitude is about 1000-1500 m, maximum altitude of 2000 m. The area has a bi-modal rainfall regime, with mean annual rainfall ranging from 400 mm in the south to 600 mm in the north. Which is the 73% of rainfall occur in March to May, the 27% of rainfall occur in September to November [9]. The potential evapotranspiration is 700-3 000 mm [10]. The study area also dominated by savannah vegetation containing mixtures of perennial herbaceous vegetation. It has also confronted with the problem of bush expansion in the native savannah grasslands. There is no detailed information on the soils of Yabello rangelands. However, the main soils of the region comprise 53% red sandy loam soil, 30% black clay and volcanic light coloured silty clay and 17% silt and vertisols [11]. Four major vegetation types have been described as (i) Evergreen and semi- evergreen bush land and thickets, found north of Yabello, Arero and Negelle stretch, (ii) Rangeland dominated by Acacia and Commiphora trees, covering most of the rangeland area extending in central, south and west directions, (iii) Rangeland dominated by shrubby Acacia, Commiphora and allied genera, confined to water sources and depressions covering some portion of the western parts of the rangeland with barren land between and (iv) Dwarf shrub grassland or shrub grassland, in the eastern parts of the rangeland where the soil is very shallow and sandy. According to Coppock [11], woody plants contribute from 5–75% of total plant cover on the Yabello plateau depending on location 9 (Figure 1).

Methods data collection

Three kebeles (Arero, DadaTuyura and Danbal-Waccu) has been chosen to carry out this research through purposive selection techniques based on the information gathered from different aspect like similarity of terrain, soil, and land use aimed at minimizing variability in the abiotic determinants of rangeland vegetation composition and functioning and hence productivity. And rangelands that rehabilitate by using enclosure methods was selected for this research purpose in order to assessed both the qualitative and quantitative benefits of the local community from this area. Semi- structured interview, Focal group discussion was held with key informants and different stakeholders at each kebele level have been conducted to gather information. The basic issues addressed in the questionnaires include community knowledge about rangeland use, feeding frequency, duration of forage availability for use, critical period of forage shortage, and its proximity. Data of functional both from enclosure and non- enclosure rangeland area were collected to make comparison. Totally 150 respondents, 50 people from three (3) kebeles have been interviewed for the assessment. The ages of respondents is older then 25 years in order to ascertain the efficiency of their experience with impact of forage resource on the study area (Figure 2).

Data analysis

Analysis of data combined both qualitative and quantitative approaches. The analysis began from revising detailed field notes and consolidating similar information from enclosure field reports and sorted out it. The results categorized into two: the quantitative (tangible product or good that had immediate economic value) and qualitative (those that improved the welfare of the individual household, communities or overall society and the environment but cannot converted immediately into cash) [12].

Results and Discussion

Based on the data that obtained from the stockholders and interview result the enclosure rangeland area mainly used for livestock fattening, grazing, wood cutting and charcoal burning activates in all of the three sites (Table 1). And the interview result indicated that among the three enclosures rangeland site Dida Tuyura enclosure rangeland generated the highest per hectare income and had the highest number of income generating activities and income portfolio followed by Danbal-Waccu and Arero respectively which is most diversified in terms of income with 83% coming from Livestock fattening and sale it. The income rate showed that an increasing trends from time to time (Figures 3-5).

Quantitative benefits

In the rangelands area that rehabilitated mainly in the enclosures techniques fattening of cattle was the most profitable activity and mainly depends on pasture that obtained from the enclosures rangelands, and no other feeds were supplied. Those peoples who live around this rehabilitated rangeland area have livestock fatting activities based on buying thin cattle from the local market during the dry season in low price and then properly feed those cattle in the enclosure rangeland area during the time of grazing. Period with an average of from 3-6 months until it becomes fat, as they need in the local market system and until arrived the expected selling price. According to the data obtained from interview result the average buying price for a thin cattle was from 2500-3000 ETB (92-110USD) and between 3-6 month the total income profit was in average from 9,000-12,000ETB ( 350-440USD) excluding the salary that bought at the beginning. In addition, this fattening practice preformed in-group that is found in the some local area. All group members contributed in both labor (activities) and budget including operational costs such as veterinary drugs and herders wage contributed equal to the fattening practice and the profit was retained by the group and shared it at the end of the accounting year. Dry season grazing was another key utilization of the enclosures rangeland areas and generated an income for all the local community that is beneficiary from this enclosures site. Those category of the livestock grazed showed the priority of the groups managing the particular enclosure. For instance, in both site of the enclosure rangeland site the local community largely practiced for livestock fattening and for cattle and sheep dry season grazing. In addition, this mainly used to sustain the livestock

Through the dry season and drought. During the rainy season, livestock graze in the communal open rangeland and the enclosure rangeland area serve as a buffer against dry season pasture scarcity and accompanied livestock losses.

Qualitative benefits

In addition to the numerical value, those rehabilitated area have also other non- measurable importance for both the local community and the livestock and further for environmental issue. Those benefits derived from because of rangeland rehabilitation have summarized as follows Table 2 and Figures 6, 7.

In general, the central core idea for assessing the benefit of rehabilitating of degraded rangeland areas in Yabello used as a demonstration for degraded rangeland area. It can be rehabilitated and used for addressing different livelihood problems of agro pastoral community and the summary of this benefit was tried to address in Figures 3-5 and Tables 2, 3 [13]. This result was in agreement with the study conducted in northern part of Ethiopia in Tigray region. Those factors productivity, management and benefits of the rehabilitated rangeland has directly linked with its sustainability, this told us the sustainability of one is resulted the sustainability of the other (Figure 8) [14].

Table 3: Some numerical and non-numerical benefits obtained from rehabilitated rangeland area based on the data recorded from the local community during field visit.

The obtained benefit variation among the three rehabilitated area that have equal hectare size resulted from the capacity of the management of the local community together with other both biotic and abiotic factors. In Yabello, the urgent task that focused for long time activity is to carry out stepwise community mobilization and education to enable the resource users to embrace sustainable rangeland management both before and after degradation occurred. This includes making the right choices of species for restoration, controlled invasive species like Prosopis (P. juliflora) and cactus (Opuntia elatior) that are invasive and sustainable utilization (e.g. stocking density and number of grazing days) are a prerequisite to optimizing the potential environmental goods and services from the restored areas. Therefore, continued extension services and participatory education on management of the rehabilitated rangeland area to the local community groups are vital for the sustainability of the achievements attained so far.

Conclusion

From this study result we can concluded that in all study site (A1- A3) the rehabilitated rangeland mainly serve for livestock fattening, grazing purpose , wood cutting and charcoal production and among this livestock fatting is the major source of income across the whole study site and Dida Tuyura (A1) is the most productive site among the rest. In addition to these numerical benefits, the rehabilitated area also gives more non-numerical benefits both for livestock and the local community and in the end for the environmental issue. In general, we can recommend that there is a need to enhance market linkages for restored rangeland products that would then drive the adoption of rangeland restoration initiatives and those helps for sustainable utilization of the rehabilitated rangeland and in order to avoid further degradation of rangeland in the Yabello rangeland area.
