Tanzania remains heavily agricultural, with 80% of the total population engaging in subsistence farming. Rural areas are subjected to increased food shortages in comparison to urbanised areas, with a survey carried out within the country in 2017 finding 84% of people in rural areas suffering food shortages over a 3-month period compared to 64% of residents in cities. This disparity between rural and city nutrition can be attributed to various factors; increased nutritional needs due to manual labour, more limited access to food as a result of poor infrastructure, high-susceptibility to the damaging effects of nature and the "Agricultural Productivity Gap". The Agricultural Productivity Gap postulates that "value added per worker" is often much lower within the agricultural sector than that found within non-agricultural sectors. Furthermore, allocation of labour within the agricultural sector is largely allocated ineffectively.
