Allowing Space for Nature: Rewilding to Heal the Earth

The term “rewilding” often elicits strong emotions, especially as presented in the media. Thus, anger is provoked that farmers will be forced to waste precious cropland, letting it return to the wild, or from fear that dangerous animals will be released into the urban environment. With equal fervour, others, taking an approving view, comprise the growing movement of guerrilla rewilders, secretly breeding butterflies, birds and beavers, and illegally releasing them (e.g., “beaver bombing”) across the countryside. In truth, rewilding is a complex and widely encompassing proposition, which can be considered as a strategy within the natural climate solutions (NCS) [nature based solutions (NBS)] approach, aimed to restore and enhance wetlands, grasslands, forests, agricultural lands, seascapes etc. While exact definitions may vary, a key feature is that (after some initial support) it minimises the level of human intervention/management in a given region, instead encouraging natural processes to take the lead and self-manage, in the restoration, shaping and enhancement of natural ecosystems and of critical ecosystem functions. The resilience of such ecosystems should also be considered, especially in regard to how the impacts of a changing climate may prevail upon them. Rewilding is informed by science, traditional ecological knowledge (TEK), and other local (indigenous) knowledge. It is a long-term process with dynamic changes occurring over time, and rather than focussing on reaching a fixed endpoint, provides a continuous journey of letting nature’s processes unfold. This can lead to increased biodiversity, amelioration of and resistance to climate change, and the provision of ecosystem services, benefitting both nature and people, including economic opportunities for local and indigenous communities, along with improved overall health and well-being. Despite its manifold and clear benefits, rewilding (along with other NCS) is not a pancea for all our troubles, many of which are rooted in the systemic issue of human ecological overshoot, and it is this that must be addressed to begin fixing the current global polycrisis.
