It has been found a chllange through application of in situ conservation of natural trees like osyris lanceoleta since rapid human population growth and dramatically change the demands of fuel wood and agriculture investement, the available natural strands of valuable plants of African sandalwood have not been able to meet the demands of the people in world specifically developing countries. How ever, this study via using the advances of plant propagation method it provide new options for conserving and multiplication of Osyris lanceolata species using in vitro culture techniques of using IBA hormone by taking plant material of the targated plant. Propagation of African sandalwood (Osyris lanceolata) by rooting hormone of IBA in non-mist poly-propagator was investigated by taking young stem of osyris lanceoleta from Bazawit Hill and we provide an alternative propagation technique to the use of seeds. This Hill is near to Bahrdar town , Ethiopia.New leaf were initiated on the young stems of the osyris after six weeks of the experment.The influence of IBA as rooting promoter at three concentrations (50, 100 and 150 ppm) were recorded.Un expectedly,from the data collected it was observed that the success 83.3% can be achieved from young stem of un treatead cuting gave a new leaf and 50% were achived in the treatead plant, this propagation technique is a viable alternative to seed. The success may influenced by application orgin of a stem cutting with a type of soil.

In Ethiopia, bamboo shoot of the two indigenous species is traditionally used for food. However, information on nutritional profile of the two indigenous bamboo species and bioavailability of important mineral elements is limited in the country. This paper describes the proximate and mineral composition of bamboo shoot of the two indigenous bamboo species of Ethiopian (Arundinaria alpina and Oxytenanthera abyssinica). Shoot samples, height 10-30 cm, were collected from North western Ethiopia and analyzed for their nutrient and mineral contents following the methods developed by Association of Official Analytical Chemists. The results indicated that A. alpina shoot has higher protein, Ca, P and Crude Fiber and low HCN contents. On dry weight basis, A. alpina contains 31.33% protein, 12.17% crude fiber and 13.67% ash. The mineral content, in mg/100 gm of bamboo shoots, was found to be potassium 1661.17, calcium 369.5, phosphorus 887, and sodium 17.33. O. abyssinica shoot has almost similar nutrient content to A. alpina shoot except difference in very few mineral elements. O. abyssinica shoot has higher potassium. On dry weight basis, it contains 27% protein, 8.67% crude fiber, and 11.33% ash. Its mineral contents in mg/100 gm, dry weight basis, were potassium 4737, calcium 203.8, phosphorus 704 and Na 16.67. The values for tannin and phytate are higher for A. alpina but with very low (below detection level) hydrocyanic acid. The result indicated that mineral and proximate contents also vary depending on location and species. Shoot size has no significant effect on proximate and mineral contents except tannin that increased with shoot size. Generally the two indigenous bamboos have good nutrient profile. Developing improved processing techniques that enhance bioavailability of Fe in bamboo shoot foods of indigenous species is required.

However, the desired results have not been achieved, as most efforts have lacked proper methodologies, follow-up and farmers' participation. Participatory tree species selection, planting and management research was conducted from 2002 to

There is a strong push within national and international arenas to move toward broader units of analysis and intervention, including the landscape, catchment and watershed. However, there is a current imbalance in the strong momentum behind this shift and the paucity of methodological guidelines for operationalizing these new approaches within research and development (R&D) circles. This paper outlines an approach for grounding watershed management in local incentives for improved natural resource management (NRM) beyond the farm level, addressing component-specific contributions to landscape degradation, and bringing formal research contributions to bear on a demand-driven NRM agenda.

There is a tendency to treat (agro)forestry as a largely technical enterprise with only positive social and environmental consequences. Yet the interactions between trees and other system components (and resource users) are significant, and can be both positive and negative. There is a critical need to institutionalize an emphasis on A Methodology for Understanding Niche Incompatibilities in Agroforestry

Tensions created through regulation (i.e. conservation versus livelihoods, rural versus urban interests, local versus global services) have made enforcement difficult. Results include encroachment on protected areas and a breakdown in environmental governance and enforcement. Environmental service (ES) reward systems (incentives) represent a promising alternative to regulation, enabling livelihood and conservation goals to be more easily reconciled.

However, there are little/no practical experiences or documented indigenous knowledge on how traditional people identify and select high biomass producing plant species with short rotation periods at Boset District. Therefore, the present study was aimed at: (1) selecting and documenting high biomass energy producing plant species at Boset District; (2) identifying major predictor variables that influence the prioritization and selection of species; and (3) develop a Generalized Linear Model (GLM) to predict the selection of species. Methods: A total of 96 informants comprising 59 men and 37 women between the ages of 18 and 81 were sampled. Data were collected using structured interviews, guided field walk, discussions and field observations. Results: Collected data indicated that 88.5% of the informants involved in firewood collection, while 90% p...

Among economical imprortant plants an attempt has been made to develop a propagation method for African sandalwood (Osyris lanceolata) by air layering approach aiming at providing an alternative propagation technique to the use of seeds or cuttings that germinate or root poorly. Air layers were applied root hormone to the stem branches of Osyris lanceolata (still attached to the plant) during Novmbere 2019, at Bazawit Hill,Nothern Ethiopia at edge of Blue-Nile River from its source at Lake Tana .Root initiation were starts after 12 weeks of the experments.The factors assessed in this experiment were the effect IBA as rooting promoter at three concentrations (0,50, 100 and 150 ppm) .

Accordingly, the objectives of this study are (1) to analyse farmers’ decisions in making use of woody plants under perceived constraints and (2) to analyse influencing factors that determine the deliberate tree and shrub growing behaviour. The methodology bases on the approaches of the ’Farming Systems’ and the ’Behavioural Decision-Making’. Influence diagrams are constructed incorporating the perceived utility and decision determinants of deliberately grown woody plants. Modelling of the tree adoption behaviour of farmers employs the ’Discriminant Analytical Approach’ taking into account the identified external and internal influencing factors. Results from the decision modelling reveal that woody plants are grown on-farm in view of the perceived utility of the species, p...
