Bioversity International is a global research-for-development organization. We have a vision – that agricultural biodiversity nourishes people and sustains the planet.
We deliver scientific evidence, management practices and policy options to use and safeguard agricultural and tree biodiversity to attain sustainable global food and nutrition security.
We work with partners in low-income countries in different regions where agricultural and tree biodiversity can contribute to improved nutrition, resilience, productivity and climate change adaptation.

Released and promising crop varieties of mountain agriculture in Nepal (1959-2016)
This catalogue of released and promising crop varieties for mountain agriculture in Nepal is the result of the combined efforts of many plant breeders who were closely involved in crop improvement in Nepal from 1959 to 2016. This catalogue aims to compile agromorphological characteristics and digital pictures to distinguish the varieties from various sources.
Using dendroecology to determine growth rates of mahogany and cedar in community forestry in Guatemala
One of the main technical knowledge gaps for sustainable timber production in tropical forests is the lack of reliable information on tree growth, which is indispensable for defining cutting cycles and estimating harvest volumes. We applied dendroecological methods to measure and model the diameter growth (dbh) of mahogany Swietenia macrophylla and cedar Cedrela odorata in humid tropical forests of community-managed concessions in the Maya Biosphere Reserve, Petén, Guatemala. The width of growth rings was determined in increment cores from 32 trees of S. macrophylla and 27 of C.
