This project is about the restoration and reuse of coal mines. The background of the project is the unemployment of a large number of coal miners in Wales after the closure of the mines. Meanwhile, the steady increase of fertiliser prices has led to an increase of farmers' costs. As a result, the agricultural output of Wales has dropped sharply. The government has put forward a series of policy incentives to support employment and help agricultural production.

It is the legal obligation of the mining company to repair the pit. The design process of the project is to start from the pit company, hire the unemployed miners to transform the mining area into a suitable site for agricultural production, so that the pit company can help the retired miners to transform through tenant farmers, help them to obtain low-cost high-quality fertile soil, thereby increasing agricultural production and driving the economy.
