Authors: Vincent Ricciardi, Zia Mehrabi, Hannah Wittman, Dana James, Navin Ramankutty 2021 Abstract Small farms constitute most of the world’s farms and are a central focus of sustainable agricultural development. However, the relationship between farm size and production, profitability, biodiversity and greenhouse gas emissions remains contested. Here, we synthesize current knowledge through an evidence review and meta-analysis and show that…
Authors: Andrea De Stefano, Michael G. Jacobson 2017 Abstract Agroforestry systems may play an important role in mitigating climate change, having the ability to sequester atmospheric carbon dioxide (CO2) in plant parts and soil. A meta-analysis was carried out to investigate changes in soil organic carbon (SOC) stocks at 0–15, 0–30, 0–60, 0–100, and 0 C 100 cm, after land…
The magic pizza pie of climate change solutions has several big fat slices marked “trees”. People have noticed, which is why we have trillion tree campaigns, billion tree campaigns and hundreds more. Yet such well-intentioned efforts can do a lot of damage if not informed by science (just look at the disasters of Europe’s biofuels and biomass policies). Not every…
Since we modern humans started spreading across the planet, we have killed off the megafauna of every continent but Africa (we evolved there, giving the local wildlife time to become wary of us) and Antarctica (not much megafauna to be had on miles of ice). Today, we live in a world in which on average, wild species have seen their…
With all those well-meaning efforts to plant trees out there, alarm is justifiably being raised that sometimes, those trees will do more harm than good. That’s why it’s helpful to start any tree project with the thought that the objective is to “regenerate with trees” or “restore with trees”, rather than “planting trees” or even “growing trees”. After all, the objective of…
LISTEN HERE Listen to a talk about “The history and future of agroforestry” with our board member, treasurer of IUAF, Patrick Worms for Regenerative Skills. In farming, the industry has convinced farmers, that the only goals that matter is yield and efficiency. That is great for the industry, but a disaster for farmers. Patrick WORMS
