In this article, we discuss the ongoing Data Revolution in relation to climate action in agriculture. Data are highly relevant for climate action, as climate change makes current local knowledge increasingly irrelevant and requires smarter management of agricultural systems. We discuss five dat...

This chapter reviews the potential impacts of climate change on on-farm conservation of crop diversity and on the contribution that on-farm conservation can make to agricultural adaptation to climate change, and ask two questions: (1) How might climate change affect the viability of on-farm conse...

Las sequías en el Corredor Seco de Guatemala están afectando crecientemente la producción de cultivos de subsistencia, el empleo rural y la seguridad alimentaria de las poblaciones más vulnerables. El escaso acceso a información adecuada y oportuna es uno de los principales cuellos de botella par...

Participatory methods to characterize farmers’ needs and preferences play an important role in plant breeding to ensure that new varieties fulfill the needs and expectations of end users. Different farmer-participatory methods for priority setting exist, each one responding differently to trade-o...

Climate variability is a major source of risk to smallholder farmers and pastoralists, particularly in dryland regions. A growing body of evidence links climate-related risk to the extent and the persistence of rural poverty in these environments. Stochastic shocks erode smallholder farmers' long...

The working paper presents a new toolkit for the implementation of a participatory vulnerability assessment (PVA) in rural localities, by introducing the methodology, as well as the findings, from a pilot study in Sokoine (Zepisa, Hombolo Ward) in Tanzania. It is based on a participatory methodol...

In Guatemala, seasonal acute food insecurity related to extended dry periods is a recurrent phenomenon. Public response is often too late and ineffective. One principal obstacle for decision-makers lays in the absence of timely, reliable and relevant information at the right scale. The impact of ...
