Trees on farms: Tackling the triple challenge of mitigation, adaptation and food security
Human induced change of ecosystems over the past 50 years has resulted in an unprecedented and largely irreversible loss of biodiversity. If these trends continue the ability of ecosystems to provide basic needs for food water timber, fibre and fuel will diminish. Reversing the trends requires significant changes in policies, institutions and practices. Agriculture, forestry and livestock management are strong contributors to climate change, currently accounting for approximately 20% of greenhouse gas emission.
