As Tanzanian cities grow, especially with substantial rural-to-urban migration, there is a need to value, nurture and restore the essential connection between nature and people within these cities, so as to enhance the life-giving benefits provided by nature. For example, in Moshi, Arusha and Dar es Salaam, abundant rivers and green spaces can be protected, restored and used to attenuate flooding, to cool the cities, and to create space for food gardens and recreation.
