Deciphering the Biodiversity-Production Mutualism

How can we manage our planet, so we produce enough healthy food without destroying our life- support system? How are increasing demands for agricultural commodities resulting in offsetting biodiversity conservation?

The answer to these and many other questions is provided in a new publication in Trends in Ecology and Evolution. Alongside Ralf Seppelt, Channing Arndt, Michael Beckmann and Thomas W. Hertel, the UPSCALE coordinator from Leibniz Universität Hannover, Emily A. Martin co-authors new paper “Deciphering the Biodiversity–Production Mutualism in the Global Food Security Debate” [1] for a comprehensive analytical framework including application to Sub-Saharan Africa.

The publication, now listed as part of the reading list of the UN Food Systems Summit 2021, lays out a comprehensive analytical framework accounting for multitrophic biodiversity-production processes; bridges disciplinary boundaries between agronomy, agroecology, economics, and conservation science; and elucidates the strong interactions of ecosystem functioning with food security and malnutrition. By applying consistent frameworks which take into account all aspects of the biodiversity-production mutualism (BPM), research merges with agroecological principles in global food systems providing informed assessments of green total factor productivity (TFP) and contributing to avoidance of lock-ins in the global food chain due to over-intensification and biodiversity loss.

Striga weeds

Striga or 'witchweeds' are parasitic weeds that affect cereal crops in many parts of Africa, reducing production from 30 to 100%, or complete loss of the crop. If maize plants are attacked by both stemborers and striga weed, the yield... Continue Reading…

Can PPT Help Farmers Adapt to Climate Change?

Yes! It helps with climate adaptation:
Desmodium enriches the soil and suppresses weeds.
The PPT improves soil moisture retention.
Trap crops provide livestock fodder, diversifying farm benefits and income.
