The R package gdistance provides classes and functions to calculate various distance measures and routes in heterogeneous geographic spaces represented as grids. Least-cost distances as well as more complex distances based on (constrained) random walks can be calculated. Also the corresponding ro...

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...

La Evaluacion Participativa Masiva (EPM) es un nuevo enfoque para evaluar variedades y otras tecnologias agricolas en finca, bajo condiciones representativas. A traves de un proceso de experimentacion sencillo y practico, los agricultores identifican innovaciones que les benefician realmente. EPM...

Triadic Comparisons of Technologies (tricot), is a new approach to test crop varieties and other technologies on-farm, under realistic conditions. Through simple and hands-on experimentation, the participating farmers identify innovations that will be of real benefit to them. Tricot is a ready-ma...

This chapter will review the evidence that shows that farmers’ access to seeds has an impact on the sustainability of food production and consumption. Diverse seeds are needed to support the diversification of agriculture, which in turn may contribute to more diverse diets, and to using species a...

Crop adaptation to climate change requires accelerated crop variety introduction accompanied by recommendations to help farmers match the best variety with their field contexts. Existing approaches to generate these recommendations lack scalability and predictivity in marginal production environm...
