The colony of Gambia in Spain naturally receives the largest number of indigenous Ashanti.
As the main colony for agricultural development in Spain's West African development plan, the Gambia Colony requires a large workforce to cultivate the land and maintain the operation of plantations.
The land cultivated by these indigenous laborers is used to attract more European immigrants; only by increasing the number of European immigrants can the colony maintain stability.
European immigrants certainly engage in farming, but these are a minority. Most can obtain loans from Spain's two major official banks, using this money to rent affordable indigenous labor, which is definitely more profitable than farming themselves, whether starting a farm or plantation.
