Cost-effective cassava processing: case study of small-scale flash-fryer reengineering por Tran, Thierry, Abass, A., Taborda Andrade, Luis Alejandro, Chapuis, Arnaud, Precoppe, Marcelo, Adinsi, Laurent, Bouniol, Alexandre, Ojide, Makuachukwu, Adegbite, Suraju Adeyemi, Lukombo, Simon Singi, Sartas, Murat, Teeken, Béla, Kuate, Apollin Fotso, Ndjouenkeu, Robert, Moreno, Martín, Belalcázar, John Eiver, Becerra López-Lavalle, Luis Augusto, Dufou, Dominique

“…As a result, small-scale production of cassava starch and HQCF often incurs high production costs, incompatible with market prices of fnal products. Taking stock of this situation, RTB scientists have developed several innovations to optimize energy effciency and costs, including a longer drying pipe, reengineered heat exchanger, larger blower for higher air velocity, and a higher product/air ratio. …”

The pathway to genetic gains in Ethiopian dairy Cattle: Lessons learned from African Dairy Genetic Gains Program and tips to ensure sustainability por Meseret, Selam, Gebreyohanes, Gebregziabher, Mrode, Raphael A., Ojango, Julie M.K., Chinyere, Ekine, Hassen, A., Tera, Asrat, Jufar, B., Kahumbu, S., Negussie, E., Okeyo Mwai, Ally

“…The great achievement has been realized due to existence of systematic animal identification and consistent performance recording, both of which are crucial for sustained national genetic evaluation, identification, and use of genetically superior and locally adapted dairy breeding stock. Furthermore, identifying roles and responsibilities, and strengthening collaboration among key dairy actors and strong government leadership and support are mandatory to build sustainable breeding program.…”

Farmers management of fluctuating market prices for wheat and oilseeds por Beck-Friis, Caroline, Linde, Vilhelm

“…The results of the study show that the choice of using either futures trading or fixed-price contracts is primarily based on market interest in stock exchange trading. Furthermore, the argument is that some production risks are eliminated when applying standardized futures contracts. …”

Driving factors of tree biomass and soil carbon pool in xerophytic forests of northeastern Argentina por Sione, Silvana María José, Wilson, Marcelo German, Ledesma, Silvia Gabriela, Gabioud, Emmanuel Adrian, Oszust, José Daniel, Rosenberger, Leandro Javier

“…The vertisols showed a 27.8% higher soil carbon stock than alfisols. Conclusions: The relevance of our study stems from a dearth of information on carbon pools and their drivers in xerophytic forests, and in particular, the importance of this ecosystems’ type for Argentina, because they cover 81.9% of native forest area. …”

Carbon accrual rates, vegetation and nutrient dynamics in a regularly burned coppice woodland in Germany por Borchard, Nils, Adolphs, T., Beulshausen, F., Ladd, Brenton, Gießelmann, U.C., Hegenberg, D., Möseler, B.M., Amelung, Wulf

“…Mature beech and spruce forests (i.e., >60 years) were also sampled as reference sites: to provide a hint of what might occur in the absence of human intervention. We measured stocks of SOC, BC, NO3‐N, P, K, Mg, as well as cation exchange and water‐holding capacity, and we mapped plant composition to calculate species richness and evenness. …”
