The proportional allocation of this sample did not yield the minimum sample size for some of the sparsely populated regions hence a power allocation with some adjustments had to be carried out as a compromise procedure while keeping the overall national sample fixed.\n\nIn general,10 agricultural households were sampled from each of the selected PSUs thus having a larger spread of the sample across the population of agricultural households. However, in some of the southern regions having less communal farming activities, the sample size per PSU was raised to 16 agricultural households. \n\nSample design\nA stratified two stage cluster sample design for the communal sector was used. At the first stage, primary sampling units (PSUs) were selected with Probability Proportional to Size (PPS) from the sampling frame based on the Enumeration Areas of 2011 Population and Housing Census. The size measure of a PSU in the sampling frame was the number of agricultural households which was derived from the questions included in the 2011 Population and Housing Census as per the World Programme of Agriculture 2010 (WCA 2010) Handbook recommendations. \n\nThe main strata was the regions which are also the primary domains of estimation. The frame units (PSUs) were further stratified implicitly by the constituencies within the regions. The list of agricultural households prepared within a selected PSU formed the secondary sampling frame from which a sample of agricultural households was selected systematically. \n\nA third stage of sampling was introduced to measure objectively the average yields of the three major crops namely; Maize, Sorghum and Millet for the purpose of estimating the production instead of the farmer's estimates. Hence a crop cutting experiment was conducted to measure the average yield of these crops. A list of plots under each of these crops in a sampled PSU was made using the plot information of the selected households within the PSU. These lists then formed the sampling frames for each of the crops in the PSU.\n\nThree plots were then randomly selected from each of the crop lists. If the list contained less than 3 plots then all were included in the experiment. An area was marked within the selected plot according to the FAO guidelines. Matured crops inside this marked area were cut and the weights from wet as well as dry grains were recorded. Grains were weighted while wet as well as dry. These figures were then used to estimate the average yield of each of the crops.","coll_mode":["Face-to-face [f2f]"],"research_instrument":"Computer Assisted Personal Interview (CAPI) replaced the conventional paper questionnaire.","sources":[{"name":"","origin":"","characteristics":""}],"coll_situation":"Data collection  \n\nData collection and capturing carried out during the NCA 2013\/14 was done following international best practices. The enumeration was conducted face-to-face using Computer Assisted Personal Interview (CAPI) replacing the conventional paper questionnaire (PAPI).   This approach helped to minimize errors during data capturing and fast tracking data processing. In contrast, information on crop cutting was collected on paper forms and captured in MS Excel at a later stage. \n\n\nProcedures\n \nA technical subject-matter planning team, consisting of staff members from NSA and MAWF was established to guide the entire census process from planning to implementation. A two day user-producer workshop with various stakeholders was conducted were the draft questionnaire, structure of the census; census methodology; definitions and concepts; and the activity plan were discussed and agreed upon. It was agreed in principle that the census will strictly follow the recommendations from the 2010 Round of the World Census of Agriculture (WCA) document of the FAO. The pilot survey was carried out during December 2013 and the survey instruments were finalized shortly after that.   \n \nIn January 2014, a one week Training-of-Trainers (ToT) followed by a two week intensive training period for enumerators and team supervisors was conducted in four training venues. A team of four enumerators assigned to one supervisor were constituted and dispatched in the field across the whole country. \n\nThe Communal sector census was officially launched on 17 February 2014 and was conducted in two phases. The first phase which started on the 17 February 2014 entailed listing of all households and the interview that lasted for five days. The second, which started during May 2014 covered the crop cutting phase that was used as inputs in the calculation of the yield. The entire data collection in the field work lasted until end of July 2014. \n\nA full publicity program was put in place to sensitize respondents and reduce non-response rate during the census. Each team started by paying a courtesy call to regional and local authorities in order to obtain support of various authorities. In addition, rigorous publicity was done through the print and electronic media country-wide.","act_min":"The interviewers were divided into teams of 4 interviewers for which one supervisor is assigned to every team of 4 interviewers. Thus one supervisor and 4 interviewers form one team. Number of interviewers were 708 and supervisors were 177.\n\nThe role of the Team Supervisor (TS) will visit enumerators on a regular basis during the enumeration period in order to \"spot-check\" and\/or complete check of the questions in CAPI. Supervisors also supply thier enumerators with the materials and instructions, and try to help them with any problems during the field work. \n \n \nPersonnel from the Head Office team paid visits to the field on an on-going regular basis. During these visits, spot-checking of the performance of interviewers and supervisors were carried out.","weight":"Since the PPS selection is and unequal probability selection the sample data has to be weighted. These weights which are generally called sample weights or base weights are the inverse of the inclusion probability. \n\nAlthough the expected sample agricultural households was  the responding households would be less than this number. Since the non-response was not too large and the reasons seem to suggest that there are no remarkable differences between the responding and non responding households, the responding households ( were taken as a random sample of the selected households.
