Methodology of Tanzania NCAP Project

The methodologies in the NCAP Tanzania project sits in the broader framework of vulnerability, resilience and adaptive capacity.

Rufiji Methods

The table below details the methodologies used in the Rufiji study. Household interviews, accompanied by key informant interviews conducted in late August 2006 were used to supplement the participatory rural appraisal and household survey.

Kilimanjaro Methods

The research is based on the findings of 1,000 household surveys along three profiles, east and south of Mount Kilimanjaro. This provides comparison by altitude, aspect and exposure. A pilot survey was carried out in Kiwalla village, which was chosen for its ecological and socio-economic similarities of the three profiles.

The table below shows the different data sources assembled. The methodological outline and collection of complimentary data sources allowed for comprehensive research to be completed in the Kilimanjaro region.

Three profiles were chosen for their ecological and socio-economic differences. These were the Rombo profile in the east and the Marangu and Old Moshi profiles in the south. 519 surveys were conducted in the Rombo profile, 379 in the Marangu profile and 118 in the Old Moshi profile. This allowed comparison of height, quality of infrastructure and access to physical capital.

The profile stretched over four miles and decreased in altitude from 5,700 to 3,700 feet. Rombo A and B were mostly banana and coffee plantations with a diversity of subsistence food crops and an increasing amount of maize further down the profile. In Rombo C, the change in food crops was noticeable and largely attributed to water availability. The banana plants were considerably smaller or replaced by such drought resistant crops such as sorghum, finger millet, maize and cow peas.

Rombo A and B population density is 480 to 500 people/km² and the annual rainfall is between 1 000 and 1,750mm. Rombo C has a population density of 280 to 320 people/km² and the annual rainfall is considerably lower compared to the higher lands with a range between 725 and 1,250mm.
