Paludiculture in action. Chain-drive equipped tractors are a prerequisite for agricultural activities on rewetted peat soils. (Tobias Dahms)

Wet agriculture could protect peatlands and climate, but remains largely unexplored

Drained peatlands contribute five per cent of global carbon emissions. Paludiculture, or agriculture on wet peatlands, protects peatlands and allows farmers to maintain their livelihoods.
Since he was elected in 2018, Doug Ford and the Progressive Conservatives have made big changes to the province’s environmental policy, which some say are are harmful to endangered species and aren’t aligned with the fight against climate change. THE CANADIAN PRESS/ Geoff Robins

Canada’s marine conservation toolbox needs an overhaul to counter climate change

It is time to acknowledge and address the rapid shifts in Canada’s oceans. To meet this challenge, Canada’s marine conservation toolbox — starting with the Oceans Act — needs an overhaul.
Changes in climate affect the timings of various points in the life cycle of plants, including when flowers bloom in spring and when leaves wither in autumn. (Shutterstock)

Climate change is altering the seasonal rhythm of plant life-cycle events

Climate change is modifying the timing of recurrent life-cycle events with critical consequences on ecological and economic levels.
