Miriam Jones: Peat that’s harvested as we speak might be a whole bunch or hundreds of years previous. It may be harvested a lot quicker than it accumulates, so one drawback with a horticultural peat harvest is {that a} nonrenewable useful resource is being depleted.
Jorge Hoyos-Santillan: These days, many of the imports and exports of peat are associated to agriculture, horticulture and flower packing. Sadly, to extract peat it’s essential to take away the vegetation cowl and it normally requires draining the peatlands to ease the extraction. By altering the hydrology and eradicating the vegetation, the general carbon steadiness within the peatland normally shifts from carbon sink to carbon supply. By way of local weather change mitigation, peat extraction is a internet contribution to international warming. Worldwide peat extraction is an enormous financial exercise; Canada and the European Union are the most important exporters.
Sophie Wilkinson: Peatland conservation and its monumental potential to assist mitigate local weather change is gaining traction throughout many international locations. Final 12 months the U.Ok. laid out a plan to ban the usage of sphagnum peat in industrial compost. This may scale back the necessity for peat harvesting. Nevertheless, provided that there are few reasonably priced or sustainable options to peat compost, there’s a fear that compost producers will import peat to fill the demand, resulting in a destructive impact on peatland situations globally, even when these within the U.Ok. are higher conserved. This exemplifies the necessity to embed peatland conservation into coverage on a global scale, to make sure that actual progress is made and sustained.
Edward Struzik: There are options to peat, like blends of coconut and wooden fiber, however they are typically costly, not as broadly accessible in North America as in Europe and never as efficient as pure peat. However lately, the standard of those merchandise has vastly improved, so it’s value giving them a attempt, together with the brand new compost comprised of family waste.
