Adoption pathways for new agricultural technologies: An approach and an application to Vertisol management technology in Ethiopia por Jabbar, M.A., Beyene, H., Mohamed-Saleem, M.A., Gebreselassie, S.

“…The literature on technology adoption distinguishes between diffusion (generally viewed as a dynamic process) and adoption (usually seen as static and specific to a point in time). Consistent with this, empirical studies on agricultural technology adoption generally divide a population into adopters and non-adopters, and analyse the reasons for adoption and non-adoption at a point in time, principally in terms of the socio-economic characteristics of the studied population. …”

Stakeholders’ Engagement Meeting for Developing “Remote sensing- based Information and Insurance for Crops in emerging Economies” (RIICE) in Kenya por Mathieu, Renaud, Satapathy, Sushree

“…Through its Work Package 4 “Real-Time Monitoring of Food Systems”, the CGIAR Research Initiative on Digital Innovation and Transformation seeks to improve real time monitoring of food system dynamics to inform multiple stakeholders who make time critical decisions to respond to variation and shocks, improve the flow of information for a better understanding of the food systems, and enhance digital data streams for improving decision making by food system actors. …”

Answering the call!: adapting a traditional hunting practice to monitor duiker populations por Vliet, N. van, Kaniowska, E., Bourgarel, M., Fargeot, C., Nasi, Robert

“…Hunting using the call does not significantly increase the sex bias (more males killed) obtained without the call. Compared with day time visual counts, the call method ensures a more reliable species identification because animals are better seen and for a longer time. …”

Modelling seed germination in response to continuous variables: use and limitations of probit analysis and alternative approaches por Hay, Fiona R., Mead, Andrew, Bloomberg, Mark

“…Probit-based models relating a proportional response variable to a temporal explanatory variable, assuming that the times to response are normally distributed within the population, have been used in seed biology for describing the rate of loss of viability during seed ageing and the progress of germination over time in response to environmental signals (e.g. water, temperature). …”
