On 16-20 November the Global Office (GO) of the Global Strategy in collaboration with the Badan Pusat Statistik (NSO-Indonesia), kicked off the first field testing of cost-effective methodologies for estimating crop area and yield under mixed and continuous cropping.
Data collection will take place in the districts of Gunung Kidul and Cianjur, covering approximately 200 households in each district.
The methods included in the field tests incorporate innovations in apportioning crop areas across different mixtures of staple crops. They also include testing statistical relationships between expensive (objective) and more cost-effective (subjective) methods to reduce sample size, and analyzing the differences between using the latest Computer Assisted Personal Interview (CAPI) technology and tablet area measurement, and traditional methods such as Paper Assisted Personal Interview (PAPI) and farmer inquiry.
Thanks to the close collaboration with BPS, the GO and its research partner, the Indian Agricultural Statistical Research Institute (IASRI), have provided training on use of CAPI technologies and other methods described in the study on measurement of crop area and yield. Badan Pusat Statistik is leveraging the field test to increase their capacity to implement CAPI surveys and improve their methods for estimating crop production under mixed cropping. A further innovation is the collection of geo-spatial information in listing by using the CAPI software to optimize logistics during the data collection process.
Similar tests will be conducted in Rwanda and Jamaica starting in January 2016. The results will be synthesized in a final Handbook on Measuring Crop Area and Yield Under Mixed and Continuous Cropping.
