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. …”

Guanaco abundance and monitoring in Southern Patagonia: distance sampling reveals substantially greater numbers than previously reported por Travaini, Alejandro, Zapata, Sonia Cristina, Bustamante, Javier, Pedrana, Julieta, Zanón Martínez, Juan Ignacio, Rodriguez, Alejandro

“…Results: We found considerable spatial variation in density (1.1 to 7.4 ind/km2), with a mean value of 4.8 ind/km2, which is more than twice the mean value guessed for central and northern Patagonia. Consequently, guanaco numbers in Santa Cruz were estimated at 1.1 million individuals (95% CI 0.7 to 1.6), which almost doubles current estimates of guanaco population size in South America. …”
