This case study evaluates the socio-economic and environmental impacts of value chain activities related to three traditional livestock systems in Tanzania: i) pastoral cattle (Maasai); ii) backyard poultry; and iii) smallholder dairy. To carry out this TEEBAgriFood analysis, researchers used an ecosystem services model of the Maasai steppe, value chain and household income models and the Global Livestock Environmental Assessment Model (GLEAM). The aim is to improve decision-making in livestock production policies, to enhance its viability, not just economically but also socially and environmentally.
Two policy scenarios have been distinguished: a baseline scenario describing the current system and an improved scenario with a policy to increase the efficiency of livestock systems taking into account the social system and the ecosystem.
