Abstract

Many development projects in Africa aim to improve the livelihoods of the people. These projects often assess livelihood indicators through baseline surveys that are executed at the household level. The point-based observations are extrapolated to the surrounding region for which the livelihood indicators are then deemed to be accurately enough described to allow the formulation of a strategy and to assess the impact of a project. However, there is no consensus of how these surveys should spatially be designed and how many observations are necessary to accurately estimate the properties of the region. In this study the statistical interference and the spatial correlation of three independent baseline surveys in South Kivu in the Democratic Republic of Congo are compared. The surveys vary in spatial distribution and in sampling size but are similar in content and have been realized at about the same time. From each survey ten indicators are selected that describe the human, financial, social, physical and natural livelihood capitals of the regions’ population. There are significant statistical differences and similarities between some of the livelihood capitals that can be largely contributed to the spatial configuration of each of the three surveys. However, in many cases the variability within specific villages is as high as the variability within the entire region. Therefore, we recommend that common livelihood indicators (e.g. descriptions of population means and distribution) can be obtained by surveys that focus on a limited (e.g.
