12.10 A series of international courses is available on related subjects. FAO organizes a number of National Demonstration Centres (NDCs) for groups of neighbouring countries. NDCs are normally organized by a country preparing an agricultural census and, as part of requested preparation assistance, FAO can provide training for a period of three to four weeks to neighbouring countries using FAO technology and methodology.

Training at national centres

12.11 Persons trained at national training centres are likely to become very important in the census taking, and the success of the census operation will depend on the quality of their work and the enthusiasm they can generate among their co-workers and field staff. Their training should not only cover the enumeration work, but also cover the broader aspects of the agricultural census. These trained personnel can train enumerators and supervisors in census work and, subsequently, supervise their work. It would be desirable to include in the training plan the experience of past censuses and the use made of the data collected. Information regarding agricultural censuses carried out in other countries may also be useful training material particularly for countries not having census experience. Training should also cover the preparation and use of cartographic maps.

12.12 Actual contents of the training package for census staff will vary from country to country, depending on the status and development of agriculture. The broad areas on which emphasis in training should be made are as follows:

1. Training should be both theoretical and practical. Experience shows that practical training in simulated census situations is important in helping the trainees understand the theoretical aspect and in preparing them in advance for various problems and complications which may arise during their work. Group discussions are also useful.
2. The training should be centralized if possible, since this provides unified training on one subject from one instructor. This could be done for census staff and provincial supervisors on a national basis, while local supervisors and enumerators are trained at the provincial level.
3. Training should be directed at the work and responsibility of each group. Supervisors are to be trained by those who designed the census, and enumerators by supervisors who have already been trained.
4. Census personnel should be screened and a final selection made on the basis of a written examination plus an interview at the end of training to ensure they are qualified to do the work.
5. Training should instill the serious nature of the work and ensure positive participation during the training course.
6. Training should be carefully organized and outlined with an appropriate agenda and time schedule.
7. The training staff should meet after each training session to discuss the days' work and evaluate trainees according to their participation, and to discuss the next day's programme.

Duration and content of enumerator training courses

12.13 The number of enumerators in the agricultural census may be quite large, particularly in a large country organizing a complete enum eration census. In China, more than four million enumerators are considered necessary. It is clear that all these people cannot be trained at one centre and that many levels of training should be envisaged. Such training could be organized at a provincial level with a number of training centres established throughout local areas. Training should be unified and given at the same level by employing master trainers who could be trained in a central provincial office. Those engaged in training at these centres could be instructed originally at the master training centre. The master trainers could be selected from the headquarters' supervisory staff.

12.14 Instructions for and training of enumerators are most important because the quality of the census results depends almost wholly on enumerators. The instructions for enumerators, should be contained in well-prepared manuals written in simple local languages (see Chapter 11 Instruction Manuals). These manuals serve both as an instructional text and as a reference guide during enumeration. They have to be complete and offer guidance on all major and frequently encountered problems. Manuals should take into account prior training and knowledge acquired by personnel in previous work. Preparation of these manuals is a priority, and should be undertaken by persons with a thorough knowledge and experience in the subject matter, the design of the census, and the psychology of both data collection personnel and landholders. In the case of multi-language countries such manuals should be prepared in each of the local languages.

12.15 An important aim of enumerator training is to develop enumerators' capacity to motivate respondents to give complete and accurate answers. The training should also equip the enumerators with the knowledge and skills for doing their job well, since the census is an inquiry of a special technical nature. The enumerators should have certain qualifications, including knowledge of agriculture. The training should be oriented to prepare the enumerators to:

1. Be conversant with the legal provisions of the census and know their own rights and responsibilities.
2. Approach the respondents with a sympathetic and persuasive attitude and not as an official intending to force information from the respondent. This can be accomplished through training the enumerators not only in the concepts and technical aspects of the census, but also in the art of approaching the holders properly and winning their confidence. The enumerators should be able to check data given to them by holders without offending them and appearing to doubt their word. Some enumerators will have prior experience on how to interview a holder, because they are extension workers or rural teachers, or have another occupation which brings them into contact with holders. In other cases, the enumerators will not have this experience and this part of the training is essential. The enumerators should be trained to avoid the temptation to guess possible answers to some of the questions with which the respondent may be having difficulty. The training of enumerators should include some days devoted to field work. This field work training should require the enumerators to collect data from not less than five agricultural holders. In addition, pre-prepared questionnaires containing typical errors and problems could be prepared for them to edit and review in class.
3. Read maps, prepare usable sketches, and identify individual parcels and determine their areas.
4. Be able to estimate, if necessary, the number of scattered trees, distinguish between trees of bearing and non-bearing ages, and identify important crops.
5. Be able to measure the areas of parcels and crop yields using instruments if objective measurements are adopted as a method of data collection.

12.16 The length of training will depend on many factors, such as literacy of respondents, previous knowledge and experience of enumerators, content and design of questionnaires, or whether objective measurements are used. Generally, in developed countries, training of just a few days may suffice. In developing countries 8-10 days may be appropriate and even 12-15 days if objective measurements are used.

12.17 The following subjects may be included in the training programme:

1. Background information
   1. Information regarding agricultural conditions prevailing in the country
   2. What an agricultural census is; why it is taken; its importance and use.

   6. Forms to be filled on completion of work.

Duration and content of supervisor training courses

12.18 Special emphasis should be given to the instructions for and training of supervisors. In view of the importance of the role of supervisors, they should have an intensive training programme. Normally, the field supervisory staff would be trained first by the technical officers of the executive agency responsible for the agricultural census. The supervisors will, in turn, train the enumerators or at least participate in the training. The training of the supervisory staff should also include items concerning the training of enumerators, and they themselves should be trained to become good enumerators. The supervisory staff should also be trained in the procedures for selection of enumerators (if they are given this task), publicity, preparation of field work reports, etc. They should be given actual practice in the methods of training enumerators and in checking enumerators' field work.

12.19 The training of supervisors will naturally take longer than the training of enumerators and should include field practice. The following subjects may be considered for inclusion in their training programme in addition to the subjects for enumerators.

1. Supervisors' work
   1. Their responsibility
   2. How to check maps of local areas and enumeration districts
   3. Preparation of lists of holders and how they are used and checked, using training guides.

   4. Required attendance records
   5. Action to be taken when work is not satisfactorily completed.

Use of training aids

12.20 The quality of training can be improved considerably by making effective use of training aids. Lecturing continuously becomes dull and boring to trainees and training programmes fail if the trainees do not pay sufficient attention to what is being taught. Audio-visual aids are a great help in this respect. There is a need to ensure that every enumerator understands and applies various concepts, methods and definitions in the same way. This is particularly difficult to achieve in large countries where training has to be organized through several levels of training. Good training materials in general, and audio-visual training aids in particular, are very useful for ensuring uniformity of training throughout the country.

12.21 One of the most useful aids for trainees, to understand a subject, is a film or video. A film showing, for example, methods of interviewing holders, or agricultural and living conditions of the holders in the country, would be found to be very effective in preparing the trainees for field work. Unfortunately, films are somewhat expensive to produce. Inter-country cooperation in this regard might perhaps be organized for producing a good film at a lower cost for every country.

12.22 Slides are another less-expensive audio-visual aid. Slides can be produced easily but should be prepared with a specific plan in mind. It is possible to exhibit charts, etc., on slides. Projection equipment for slides is not expensive. It is more convincing to show a slide of a map showing the boundaries of a locality and explain how these boundaries are to be used in a listing operation. Such examples can be multiplied. Teaching with the assistance of slides shown at specific intervals would lead to better assimilation of the subject by the trainees.

12.23 Charts and graphs are also very useful as training aids. The colours used in drawing a chart should generally be quite bright. The charts should be large so that they are visible from every part of the classroom.

12.24 Overhead projectors and transparencies, and the blackboard, are also very effective training tools.

12.25 Generally, lectures should be interspersed with films or slide presentations. The supervisors might also need to be trained in using training aids in the classes for enumerators.

Training in writing inspection reports

12.26 Certain reports for each census worker (enumerator and supervisor) must be completed periodically (daily or weekly) in order to measure the progress of the censusoperation and to tighten the inter-relations of various processes. The aims of these reports are:

1. To inform the authorities of the work progress and its relation to the planned time schedule.
2. To identify any deviations and problems in progress so that proper and timely action may be taken.

12.27 Enumerators and supervisors should be trained thoroughly in preparing these reports, which should be realistic and as simple as possible, with minimum data required to ensure the above aims. There should be different forms for the enumerator, the local supervisor, and the provincial coordinator.
