PET Manuals Print E-mail

AA International Ltd staff, working in emergency and post-emergency circumstances, recognised that non-agriculturalists, working in subsistence agriculture localities, require help to improve their rapid analyses of crop yields.

Experience in Ethiopia (Robinson et al, 2004) shows that a visual assessment of yield at harvest time, coupled with strategic sampling, can provide accurate and objective estimates of cereal yield but requires the preparation of a country specific manual. PET Livestock Manuals help assessors estimate and evaluate changes in the body condition of livestock. Consequently, a series of Pictorial Evaluation Tools (PET) field manuals is being produced to meet such needs.  


In 2015, AA International Ltd was contracted to prepare PET-Crops South Sudan and PET-Livestock South Sudan. The PET-Crops South Sudan was an updated version of the PET-Crops South Sudan manual which was developed in September 2006. 

The 2015 manuals can be downloaded free of charge below
