Annexes


A. Survey checklist

Market surveys

An example of a market survey is provided in “Retail markets planning guide” (Agricultural Services Bulletin No. 121, FAO Rome, 1995). The following types of information could be collected:

Setting up surveys. Surveys can be time consuming. Sufficient financial resources and a trained and competent staff are needed. Where surveys are required it is necessary to decide the following.

Social assessment methods

The methodologies used in rapid rural appraisal (RRA) or participatory rural appraisal (PRA) are very similar. For market studies they have in common the following features:

Mapping

Mapping is an integral part of the planning process. The purpose of mapping is to provide:

Approaches to mapping

There are basically two approaches to mapping, both of which may need to be applied. These can be supplemented by field survey work and the choice of method will depend on the availability of resources and equipment.

Participatory mapping. This is a method of creating maps through a dialogue with key informants, such as traders and farmers. The maps, which can be drawn on a blackboard or even on the ground, clarify the relationship between the various factors that influence marketing and highlight what is important (or unimportant) to the users. The mapping is often combined with a systematic walk through the area with the key informants, which can be useful for understanding any changes that are taking place.

Formal mapping. These are working maps used to understand existing market patterns and to identify and plan new market sites. The mapping is undertaken to provide:

The process of producing base-line maps consists of the following:

1. Collection of copies of all maps in current circulation and of any geographic information system database (if available).

2. Identification of provincial, district and village boundaries, administrative centres and market locations.

3. Drawing or redrawing of a base map.

4. Reproduction of the base map on tracing sheets.

Often the base maps are out of date. Advice on updating should be sought from the local survey department.

Site maps. The most important mapping in the whole process is preparing the site map of the market site. If adequate mapping of the market area is not available a survey should be carried out to record all the existing features within the market. The survey should be at least 1:500 scale, picking up details of levels (spot heights on a 2 to 5 metre grid, inverts of drains, slabs, breaks in slope, etc.) and the market site should be related to a fixed point. For an existing market the site map should also include all the existing buildings and other infrastructure on the site.

The survey may need to be extended to record other important features outside the market area, such as main road links and drainage outfalls. All mapping should be plotted to conform to a standard sheet size.

B. Assessment of supply and demand

This annex supplements the description of Stage 2 and outlines the methods by which survey data, combined with information on agricultural production and household consumption, can be used to estimate the potential throughput of a larger market. Where very simple market improvements are planned (for example, to upgrade existing retail market infrastructure), such steps can be omitted.

Step B.1
Reviewing crop and livestock production

Where information on market supplies does not exist, estimates can be made by looking at the available data on crop and livestock production within the market catchment area, including:

Often, local or district data collected on an annual basis can give an idea of crop production. Estimates of livestock can be more difficult, as the data that is normally collected is the number of animals (head) in the field or pen. One way of handling data on local production is shown in Form 1.

This approach only gives existing production levels. However, by looking at trends over a number of years it should be possible to identify some patterns of growth. These will be influenced by a number of factors, including the way farmers are intensifying production (increasing yields) of existing crops or diversifying into new crops (changing to higher-value crops). If no trend data is available, a simple assumption to make is that production is increasing in line with population growth.

Step B.2
Reviewing the role of market channels

Step B.1 gives an approximate idea of total production, but this has to be adjusted to take account of what is marketed and what farm households consume. A commercial farmer produces exclusively for the market, whilst a subsistence farmer grows primarily for home consumption.

Subsistence farmers are likely to rely mainly on the local retail market for their sales. More advanced farmers may use a variety of outlets, including on-farm sales and assembly markets. Large-scale commercial growers are probably better able to control their own marketing, which could be done through a mixture of contract selling at the farm gate and direct deliveries to local assembly markets or to wholesale markets in urban areas. From discussions with local officials and farmers it should be possible to obtain an overall impression of what marketing channels are presently being used, and what proportion (%) of marketed production is going through each channel (see Form 2).

Step B.3
Reviewing existing consumption data

The next step in the process requires a review to be made of what people eat. Consumption data is normally expressed as an annual average consumption for individual food items on a per capita (per person) basis, for example, 100 kilograms of potatoes per capita.

This information is often available from nutrition surveys. Alternatively, data from a comprehensive household budget survey may be available. Information may not be specific to the market catchment area, but can provide a broad estimate of what is consumed by local households.

Form 3 shows how consumption figures, by age and gender, can be used to calculate an average. These are likely to be national figures, but more reliable figures specific to the area may be available and sometimes these figures may distinguish between urban and rural households. As far as possible, local rural figures should be used. Care should be taken to use actual figures or reliable estimates. For food security purposes figures of daily food “requirements” are often announced and used in calculations of food balances. Such figures should not be used when planning markets as there is often a big difference between “requirements” and actual “consumption.”

Step B.4
Determining on-farm use

Once it has been decided what consumption figures to use it is possible to calculate the amount farm families are likely to consume of their own produce. However, farms may not be able to produce all their requirements and may need to purchase some commodities from outside, usually from a local primary market. The procedure for calculating average food requirements is shown in Form 4.

This may not be the total use of produce on the farm. To determine the farm surplus, adjustments need to be made and this will require some rough estimates to be made as shown in Form 5.

The last calculation is to determine whether there is actually a surplus from the farms. It compares the farm household needs with the production estimates derived in Step B.1, as shown in Form 6.

Step B.5
Determining non-market sales

Before estimating what might be the market throughput, the role of other marketing channels (Step B.2) needs to be taken into account. As this is influenced by many factors only a rough estimate can be made, particularly of produce sold at farm level or delivered directly to urban wholesale and urban retail markets. An illustration of the calculation is shown in Form 7, using the percentages from Step B.2 to divide the surplus between different channels.

Step B.6
Estimating market throughput

The last step is to estimate the throughput of the planned market. The basic calculation method, which is the same for both primary and assembly markets, is shown in Form 8.

If the market also trades in live animals then an allowance for this must be made. For an existing market the best guide would be what is presently traded, but for a new market an assumption will have to be made as to what proportion of the local livestock or poultry production might be sold in the market.
