Plants and Climate Change Talk

In 2019 the Welsh Government declared a climate emergency in Wales and has committed to achieving a carbon neutral public sector by 2030.

On three Friday lunchtimes in January, Growing the Future will be hosting a series of talks focusing on the impact of climate change on our plants, the research being done to tackle this and the role of botanic gardens in tackling and adapting to climate change, and conserving plants for the future.

Enjoy this FREE series while also taking advantage of FREE Garden entry on weekdays in January. Talks start at 12noon.  To book your place, please visit our Eventbrite page.

‘Healing the Earth: Biochar for Carbon Sequestration and Habitat Restoration’ by Professor Alayne Street-Perrott

Alayne Street-Perrott is a climate scientist with over 40 years of research experience on past climate changes and environmental impacts of human activity in the tropics, long-term changes in the global carbon cycle, and biochar as one of a potential range of natural solutions for combatting climate change.

Biochar is a form of black carbon produced by heating dried biomass in the absence, or near absence, of air (pyrolysis). It is similar to wood charcoal, but can be manufactured from a wide range of waste biomass feedstocks.

Biochar typically contains about 70-80% carbon, most of which is resistant to decay. When added to soils, it sequesters carbon for centuries to millennia, helping to combat global warming. It can also improve the structure, pH, nutrient content and ecology of soils, as well as immobilising a variety of pollutants. This talk will focus on our recent research on remediating bare, highly contaminated, Welsh metal-mine sites using artificial “spray-on” soils containing biochar.

Introductory talk titled ‘Conserving Welsh native plants through seed banking’ by Dr Kevin McGinn, Science Officer for the Growing the Future Project.

Kevin will talk about establishing the National Seed Bank of Wales at the National Botanic Garden and how it will help to conserve plants in Wales, including those threatened by climate change, for future generations.

Talks arranged by the Growing the Future project at the National Botanic Garden of Wales.

This project has received funding through the Welsh Government Rural Communities – Rural Development Programme 2014-2020, which is funded by the European Agricultural Fund for Rural Development and the Welsh Government.
