1. USE OF AERIAL FRAMES FOR AGRICULTURAL CENSUSES AND SURVEYS Fiji Experience

2. INTRODUCTION Aerial Frame methodology was introduced in Fiji during the last 1991 agriculture census project. Aerial Frame methodology was introduced in Fiji during the last 1991 agriculture census project. It was an alternative methodology given that there were a lot of errors in the proposed methodology as previously used in the 1978 census i.e. List and cluster sampling methodology. (errors in overlapping / duplication and omissions) It was an alternative methodology given that there were a lot of errors in the proposed methodology as previously used in the 1978 census i.e. List and cluster sampling methodology.

3. AREA FRAME PROCEDURES FOR 1991 AGRICULTURE CENSUS Divided the whole country into small blocks without any overlapping and omission that have identifiable physical features Divided the whole country into small blocks without any overlapping and omission that have identifiable physical features Overlayed the Population Census EA boundaries Overlayed the Population Census EA boundaries Stratification of EA boundaries into nine strata according to the importance, intensity and type of land use Stratification of EA boundaries into nine strata according to the importance, intensity and type of land use Further, the whole country was sub divided in to 21 sub-stratas. This activity guaranteed the sample allocation between crops. Further, the whole country was sub divided in to 21 sub-stratas. This activity guaranteed the sample allocation between crops.

4. STRATIFICATION SUMMARY Nine Stratas – Strata 10:70 -100% Cultivation – Strata 20:30 - 69% Cultivation – Strata 30:10 – 29% Cultivation – Strata 40:91 – 100% Pastures – Strata 50:100% Forests [No Census] – Strata 60:100% Non Agriculture land [No Census] – Strata 70:100% Cities & Towns [No Census] – Strata 80:100% Special Farms – Strata 90:100% Big agriculture holdings [freeholds etc]

5. PREPARATION OF AREA FRAME Transferred all EA boundaries on to topo maps Manually stratified the EAs on topo maps including sub- stratification procedures Numbering of grid boxes on stratified EA maps on a serpentine manner Randomly selected the 1294 samples Manually transfer the selected segments boundaries on to contact aerial photo following identifiable physical features with no disturbance to the area of segment Used planimeter to calculate the area of segment on aerial photo Prepared photo enlargements with all corresponding details laminated properly before sending to the field.

6. ACTIVITIES UNDERTAKEN Pilot Census conducted whereby all amendments were incorporated in the final version of survey instruments Selected 1294 SMs [photo enalrgements] as final sample for census Conducted two separate trainings; Supervisors [2wks] & Enumerators [2wks] Two months of Data collection [Jun-Jul] Conducted 7 months of data processing using SAS
