Abstract
Livestock is estimated to contribute to the livelihoods of about 60 percent of rural households in developing countries, including many poor. Measuring the exact extent of such contribution is however challenging, because of significant data gaps. This paper develops and applies a methodology to assess the contribution of livestock to household livelihoods, which allows measuring both tradable and non-tradable or marginally tradable livestock outputs. It implements it using data from Living Standards Measurement Studies (LSMS) in Uganda and Tanzania, which include a comprehensive livestock module, as well as data from ad hoc surveys implemented by the ministries in charge of livestock in both countries. Results suggest that non-tradable and marginally traded livestock outputs represent about half of the contribution of livestock to household livelihoods.

Appendix. RIGA methodology
Table 6 illustrates how this paper applied the RIGA methodology to calculate rural household income for Tanzania and Uganda, using data from TNPS wave 2012/13 and UNPS wave 2011/12, respectively. The calculation was based on FAO (2016) and FAO (2014) but slightly modified to increase comparability across the two countries. Tables 7 and 8 report that the results obtained applied this methodology, in the same format as those reported by FAO to allow for comparison.
