Past, present and future of local crop evolution

PLANTS, PEOPLE, PLANET, EarlyView.
Promoting agrobiodiversity is a promising strategy for mitigating the negative effects of climate change on global food security. We highlight the central role evolutionary processes play in harnessing the potential of local crops by integrating genomics, archaeology, ethnobotany and traditional ecological knowledge (TEK).

Governance and infrastructure as pillars of performance: A socio‐ecological analysis of Ethiopian botanical gardens

PLANTS, PEOPLE, PLANET, EarlyView.
While botanical gardens are often perceived merely as recreational spaces for a weekend walk, in the Global South, they are true lifelines for nature and for the people who depend on it. Our research in Ethiopia explored what actually keeps these gardens running long‐term.

Modeling land suitability for Coffea arabica L. in Central America [PDF]

Environmental Modelling & Software, 2017
Climate data availability plays a key role in development processes of policies, services, and planning in the agricultural sector. However, data at the spatial or temporal resolution required is often lacking, or certain values are missing. In this work, we propose to use a Bayesian network approach to generate data for missing variables.
