During the farm visits, data were collected on farm householddemographic characteristics, livestock, areas planted in various crops, information onsingle, multiple and mixed plantings of crops, farm practices, fertilizer andequipment hire costs, ownership of vehicles, farm equipment and appliances, and theproduction, sales and prices received for selected crops.Training, Data Collection and SummarizationPrior to data collection, emphasis was placed on providing adequate enumeratortraining and quality control in an effort to reduce non-sampling errors. The trainingwas held in November /December with the participation of District and PrefectureChiefs of Statistics and those training the enumerators. In addition, the Prefectureand District Chiefs of Statistics were provided training on the manual editingrequirements for completed questionnaires prior to their return to the central offices.The Survey was conducted by approximately 400 enumerators residing in or near thesample segments for which they were responsible for data collection. The Districtand Prefecture Chiefs of Statistics were responsible for conducting quality controlchecks on completed questionnaires. Where errors were noted, the enumerators wererequired to re-interview the sample farmer(s) and make the necessary corrections.Immediately upon receipt of the first survey data, additional manual edit checks werecompleted by central office staff in which districts and the data were entered directlyfrom the forms into microcomputers using a customized data entry package. Thedata were then run through a comprehensive computer edit system used for detectingdata entry, coding and enumerator errors. Necessary corrections were made in theforms and the data set in the computers. The “cleaned” data were then summarizedin tabular forms. Preliminary tables describing the results of the survey werecompleted in February.194/236
IPA 2009 Multi-beneficiary StatisticalCooperation ProgrammeInterpretation of DataAn understanding of the data and their limitations is needed for correct interpretationfor policy and planning purposes. Some of the limitations are outlined below.For the Annual Agricultural Survey, the sample size was large enough to givereasonably reliable estimates at the national level for most data items. In addition,for frequently occurring items, reasonably accurate prefecture level estimates areavailable. However, for non-frequent items (such as areas planted in minor crops),estimates are provided at the national level only.Due to the sampling method used -- weighted area frame – the Estimates providedare valid only for crop farms (i.e., farms which controlled agricultural land that mayor may not have been planted in crops). Thus, livestock only farms are notrepresented by the sample, for these cases special surveys are conducted. In addition,growers of specialty crops (such as greenhouse operators) are not included in theframe.A point system was initiated to define a “farm operation as follows.Land: 1 decares (1/10 hectare) = 50 pointsCattle: 1 animal = 25 pointsGoats/sheep/pigs: 1 animal = 15 pointsHorses/Donkeys/Mules: 1 animal = 20 pointsChickens/other fowls: 1 bird = 2 points.An operation was defined as a farm if its land/livestock holdings resulted in a totalpoint count of 50 or more.Because the Survey was a recall survey covering all planted lands, reference to totalland in the tables includes multiple planted parcel areas unless otherwise specified inthe tables.For example, if farm operator first planted wheat in a 1.0 hectare parcel and afterharvesting the wheat, then planted this same parcel in maize, the total land plantedwill usually include both wheat and maize areas.Finally, it should be noted that a customized computer program was used to generatethe information provided in this report.QuestionnaireSince 2004 the collected data were substantially increased, which made possible theestimation of national accounts. The added data are provided on:- The working days in farms from households specified for agriculture, livestockand fruit trees.- The working days out of the farm and income from these activities.- Data on the balance use production.- The expenditures in value specified for agriculture, livestock, agriculturalmechanic and other activities in the farm,- Income from the processing products,- Income for agro tourism development,195/236
