Abstract In Ethiopia, the impacts of malaria continue to cause a many number of morbidity and mortality that accounts to most outpatient observations. Ethiopia recently designed to attain nationwide malaria control by 2030 by beginning sub-national elimination in districts with low malaria transmission. However, the rises of drug-resistant parasites, especially Plasmodium falciparum hinder the malaria containment strategies. Plasmodium falciparum and Plasmodium vivax, dispersed all over the Ethiopia and accounting for 60% and 40% of malaria cases respectively. The aim of this report was to overview the phytochemical constituents, diversity and effect of some compound extracts on drug resistant plasmodium species. Many plant species, a total 200 identified by 82 studies, are used in traditional malaria treatments throughout the country. Allium sativum, Croton macrostachyus and Carica papaya were the more frequently used medicinal plants species. There are so many phytochemicals constituents found in medicinal plants used to treat malaria. Alkaloids, Flavonoids, Phenolics, Terpenoid and Glycosides are the most reported for their effective activity on drug resistant malaria.

Abstract The study was conducted in two purposefully selected zones of Oromiya Regional State, namely Jimma and Illubabor. The objective of the study was to analyse the honey-bee production and to assess hive technology preferences in the study area. A total of 156 beekeepers were randomly and proportionately selected from four districts (Mana and Gomma from Jimma and Bacho and Yayo from Illubabor). Data were collected through formal survey and secondary sources. Accordingly, the average age of the beekeepers was 40.2 ± 8.13 years with an average of 13.5 ± 6.58 years of experience. The majority of the respondents (53.2%) in the study area got their colonies by catching swarms. Three hive types (traditional, transitional, and frame hive) were found in the study area. More than 70% of the respondents harvested once a year from traditional hives, while 25% of respondents harvested up to three times per year from frame hives. Moreover, an average of 22 ± 4.6 and 16 ± 4.1 kg of honey were harvested from frame and transitional hives per year, respectively. Compared to these two hives, a much lower (7 ± 1.6 kg) amount of honey was harvested from traditional hives. Various honey-bee floras were identified in the study area. Plants such as Vernonia amygdalina, Croton macrostachyus, and Schefflera sp. produce white honey. Half of the respondents’ preferred transitional hive followed by frame hive (37.2%). Factors which affect the use of frame hives were lack of equipment (36.5%) followed by wax quality and availability problems (34%). That is why few beekeepers tried to modify the frame hive to solve the problems of wax in vertical frame hive. In order to adopt and sustain modern hive technology, the focus should be on honey-bee equipment as well as wax quality and availability.

The study was conducted in Shashemene district, Ethiopia. Management-related data were collected using informal and formal surveys. Woody species diversity and related parameters were collected from 60 households. Woody species with ≥5 cm diameter at breast height (DBH) were measured and recorded and below 5 cm were counted and recorded in 10 m ∗ 10 m and 1 m ∗ 1 m plot, respectively. A total of 36 woody species were recorded, of which 58% were indigenous to the area. The overall mean number of woody species per plot was 3.13. Four woody species, namely, Cordia africana, Croton macrostachyus, Persea americana, and Catha edulis, showed highest importance value index. Farmers’ preference ranks for selected woody species were recorded in order of Cordia africana, Eucalyptus camaldulensis, Croton macrostachyus, and Cupressus lusitanica, respectively. The similarity in woody species composition between the study villages ranged from 0.46 to 0.60. To sustain the management of woody species, farmers implemented pruning, thinning, composting, weeding, digging, and watering activities in the area. Garden availability and market and road accessibility are the major determinants of woody species in homegarden agroforestry. The study revealed woody species diversity, management practices implemented, and factors affecting woody species diversity management in homegarden agroforestry. Therefore, government should be worked on infrastructure, resource reallocation, and awareness creation in communities for the better improvement of species diversity and its sustainable management in homegarden agroforestry.

In sub-Saharan Africa, including Uganda, there is declining soil fertility and limited on-farm use of inorganic fertilizers due to poverty and limited subsidies for inorganic fertilizer use. Thus, integration of soil fertility improving tree species (SFITs) in farming systems remains a plausible option to sustaining soil productivity. However, knowledge of the effects of many of the locally growing farmer perceived soil fertility enhancing tree species on to soil chemical and nutrient contents are thus still lacking, and this has constrained decisions on their adoption and scaling up. The objectives of this paper were to identify farmers' preferred soil fertility improving tree species in agropastoral communities of Kyeizooba subcounty Bushenyi district, and characterize their litter content and assess their effect on selected soil chemical properties. Semistructured questionnaires were administered to 333 randomly selected agropastoral farmers. Litter and soils under canopy soils were sampled from three different environments: Under canopy radius (A), canopy edge (B), open pasture land up to thrice the canopy radius (C). Results revealedEucalyptusas the most common tree species on livestock farms, followed byErythrina abyssinica. The highest litter content was recorded forMarkhamia lutea(240 g/cm2under its canopy) followed byCroton macrostachyus(90 g/cm2), and 19 g/cm2Erythrina abyssinica. Nitrogen was higher (P=.02) inErythrina abyssinicalitter, K and carbon inCroton macrostachyuslitter (P=.03). These results give evidence that of soil improversErythrina abyssinica,Croton macrostachyus, andMarkhamia luteamay positively affect soil fertility. Farmers' indigenous knowledge and or valuation of important tree species can be relied on, and thus, their indigenous knowledge need to be incorporated during identification of tree species for promotion in farming systems.
