However, this resource has got less attention in national and regional planning. Hence, the objective of this study was to figure out the socioeconomic contribution of Lake Hawassa for the local and national economy and call for the concerned body (like; policymaker and planner) take possible action will be measured the lake from further degradation. A total of 164 households’ questionnaires collected from five kebeles, and thus households were selected randomly from each kebele. Then, the data were analyzed using descriptive statistics, ANOVA and linear regressions model. The result showed that the majority of households’ livelihood income strategies were from irrigation (54.8%), rain-fed (33.8%), livestock (6.5%), fishing (3.5), off-farm seasonal work (1.2) & others (0.2). The average annual total household income was 53,716.39 ETB. Out of this, lake income constituted 59.7% of the total income. The local households’ income contribution of Lake Hawassa within selected kebeles was statistically significantly different by livestock watering, pasture for grazing animals and water for washing body or close. Other are did not reveal significant differences among the five kebeles for all the parameters analyzed. Overall result confirmed that the Lake contributed significantly to the household economy of the local people and hence, it is important to protect and improve the management of the lake and its wetlands for livelihood enhancement, while also securing their long-term ecological functions..","PeriodicalId":14445,"journal":{"name":"International Journal on Environmental Sciences","volume":"109 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79620385","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of the study was to assess the welfare problem and other management constraints of working equine in the study area. A total of 120 working equine were observed for the presence of lesions, lameness, age and body condition score direct from the animal and 130 equine owners were interviewed to get information about feed type, workload and time and type of work. Most equine owners, 74.6%, were fed mixtures of concentrate, cereal, straw and hay. Proportion of working time in a week 43.8% & 35.4% were grouped 3-4 days and 5-7 days respectively and 65.4% work 6-10 hours per day. The body condition score of working equines in the present study area were poor, moderate and good with a percentage of 34.2%, 48% & 25.8%, respectively. The owners practice vaccination (12.3%), deworming (5.4%) & (43.1%) both for prevention and control of equine diseases however 30% of respondents did not practice disease prevention measures. Among the observed equine 54.2%, 25%, and 20.8% were used for pack, draught and ridding respectively. Proportion of working type between donkey (69%), horse (26.3%), and mule (4.6%) were used to pack and donkey and horse used for draught type of work with proportion of 13.3% and 86.7% respectively. On the other hand, according to obtained data horse (28%) and mule (72%) were used to riding type of work whereas donkey was not used to riding purpose in this study area. The common body lesion prevalent in the present study area 17.5%, 15%, 11.5%, and 34.2% at tail base, lip, back sore and lacrimation respectively and 12.5% of equine were lameness (66.7%), 86%, and 83%, Tail base lesions, of back sore, ribs/flank were more associated to work type of pack animal respectively. Draught type of work is likely to induce lip and mouth lesion (50%), and lameness (73.3%). In this study equine had an important value and act as multipurpose animal in the rural and urban society. However, management constraints like feed shortage, lameness, wound, over time working and overloading were found the main challenges hindering the health and welfare of equines. Therefore, further studies and necessary measures should be considered on the diseases and welfare constraints hindering efficient use of equine in the area of paramount importance.","PeriodicalId":14445,"journal":{"name":"International Journal on Environmental Sciences","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88673676","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Different levels of termite densities - 1, 2, 4, 8, 16 and 32 were used. Each density was placed in a test cage (14 x 22 x 10cm) and then exposed to 24hr starved fourth and fifth nymphal instars and adult males and females of R. kumarii under laboratory conditions (28-34°C temperature; 12 ± 1hr. photoperiod; 65-70 relative humidity). All the experimental life stages of R. kumarii responded to the increasing prey density of O. brunneus by killing a greater number of preys than at lower prey densities. Thus, the predators exhibited the type II curvilinear functional response. The maximum predation (K) was restricted to high prey density (24.889, 24.722, 22.889 and 24.194 for IV, V nymph and adult male and female respectively). The searching capacity of R. kumarii increased with increasing termite density and this reflected its predatory potential.","PeriodicalId":14445,"journal":{"name":"International Journal on Environmental Sciences","volume":"362 1","pages":"19-24"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82639678","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
