Determinants of intensity of adoption of old coffee stumping technology in Dale Wereda, SNNPRS, Ethiopia por Arega, M.

“…The country’s export earnings from this crop exceeds all other agricultural products. Low production and productivity, which are mainly associated with poor adoption of improved technology, oldness of coffee trees and poor pruning and recycling system, especially stumping, were among the major problems. …”

Effectiveness and sustainability of large scale soil and water conservation interventions in the sub-humid Ethiopian highlands: evidence from Debre Mawi watershed [Abstract only] por Dagnew, D., Guzmán, Christian D., Zegeye, Assefa D., Tebebu, Tigist Y., Akal, A., Mekuria, Wolde, Ayana, Essayas K., Tilahun, S., Steenhuis, Tammo S.

“…But, on the saturated flat bottom lands and fields dominated by vertisols (that form wide-deep cracks during the dry season and swell during the rainy season), infiltration was restricted and conservation practices became conduits for carrying excess rainfall. Our continuous observations and photo monitoring of bunds on Nitisols and saturated bottomlands indicate that installing soil bunds on these areas caused the collapse of soil bunds in to the furrows. …”

Watershed modeling for reducing future non-point source sediment and phosphorus load in the Lake Tana Basin, Ethiopia por Moges, M.A., Schmitter, Petra S., Tilahun, Seifu A., Steenhuis, Tammo S.

“…The parameter efficient semi-distributed watershed model (PED-WM) was calibrated and validated in the Ethiopian highlands to simulate runoff and associated sediments generated through saturation excess. The P module added to PED-WM was used to predict dissolved (DP) and particulate P (PP) loads aside from discharge and sediment loads of the 700 ha of the Awramba watershed of Lake Tana basin. …”

Sixty years of global progress in managed aquifer recharge por Dillon, P., Stuyfzand, P., Grischek, T., Lluria, M., Jain, R.C., Bear, J., Schwarz, J., Wang, W., Fernández, E., Stefan, C., Pettenati, M., Gun, Jac van der, Sprenger, C., Massmann, G., Scanlon, Bridget R., Xanke, J., Jokela, P., Zheng, Y., Rossetto, R., Shamrukh, M., Pavelic, Paul, Murray, E., Ross, A., Bonilla Valverde, J.P., Palma Nava, A., Ansems, N., Posavec, K., Ha, K., Martin, R., Sapiano, M.

“…Currently, MAR has reached an estimated 10 km3/year, ~2.4% of groundwater extraction in countries reporting MAR (or ~1.0% of global groundwater extraction). MAR is likely to exceed 10% of global extraction, based on experience where MAR is more advanced, to sustain quantity, reliability and quality of water supplies.…”

Breeding for fungal resistance in Musa por Hartman, J.B., Vuylsteke, D.R.

“…In Uganda, Burundi, and Rwanda, consumption of cooking bananas exceeds 200kg per person per year. The spread of the fungal pathogen Mycosphaerella fijiensis Morelet into Africa has lead to serious declines in the productivity of banana and plantain based farming systems, and lead to the establishment of a plantain breeding program at the International Institute of Tropical Agriculture (HTA) in 1987 (Vuylsteke et al, 1993). …”

Effect of fertilization on the accumulation and health risk for heavy metals in native Andean potatoes in the highlands of Perú por Orellana Mendoza, Edith, Camel Paucar, Vladimir Fernando, Yallico Madge, Luz Consuelo, Quispe Coquil, Violeta, Cosme De la Cruz, Roberto Carlos

“…As a result, it was found that the use of inorganic fertilizer and poultry manure increased the values of Cu and Zn in soils, exceeding the recommended standards. The accumulation of heavy metals in potato tubers did not exceed the maximum recommended limits with the exception of Pb, which exceeded the limit allowed by the FAO/WHO (0.1 mg kg−1). …”

Efficiency of a compound parabolic collector for domestic hot water production using the F- chart method por Ortega Quispe, Kevin Abner, Huari Vila, Oscar Paul, Ccopi Trucios, Dennis, Lozano Povis, Arlitt Amy, Enriquez Pinedo, Lucia Carolina, Cordova Torres, Betty

“…This indicates that there is a surplus of usable solar energy in the collector during the summer, while in autumn and winter, the solar contribution balances and slightly exceeds the demand. CPC can significantly contribute to the development of high Andean areas by improving quality of life, reducing costs, and promoting environmental sustainability compared to other available technologies.…”
