In a seminar yesterday, a thesis student presented a pure narrative about corn farmers’ decision-making process about seasonal climate forecast. He also flashed on the screen a theoretical decision tree that the project managers had developed. The lack of analysis suggested the need to have a systematic method to describe the problem and identify the key components.

I suggested that one way for him to make sense of the information he got from farmers, on how they had used climatic forecasts to make farm decisions and the outcomes of those decisions, was to construct historical and seasonal profiles.

In the 1990s, as theme leader in the Rice IPM Network, we conducted a series of workshops in the Philippines, Indonesia, Thailand and Vietnam to get research and extension partners to arrive at a common understanding of the pest management problems in their countries. The experts, Geoff Norton and John Mumford from Imperial College and K.L. Heong from IRRI, introduced various decision tools at these workshops – time profiles, flow charts, discrimination analysis, field force analysis, causal analysis and matrices.

What is a historical profile?

A historical profile is a tool for assessing gradual changes that their causes are making. To construct a historical profile in a workshop situation, participants are asked to recall major events that have taken place in the community with approximate dates. These can relate to the introduction of new technologies, political events or natural disasters.

This technique is used when there is a need to see current problems from a historical perspective. Through this approach, one can understand the broad dimensions of a problem, and identify constraints and opportunities for resolving them (Norton and Mumford 1993).

Participants in groups develop these profiles and the information is presented graphically in a single sheet of paper to provide a general description of the time dimensions of a problem. Graphical presentation of historical information is an effective tool to enhance communication among stakeholders with various academic backgrounds.

How to construct a historical profile
1. Identify the major factors that directly or indirectly influence the development of a particular problem.
2. Determine the relevant time period over which changes in these factors are to be considered; 20 years or more is often desirable.

A series of graphs can then be drawn, using expert opinion available in the workshop group, or from various statistical sources. The level of detail required in drawing the historical profile is simply that which is sufficient to indicate important trends and relationships. Further detail may add little to a good, rough assessment.

Uses of historical profiles

  • It provides a structured means of bringing together information on a range of aspects that may all have had some influence on the development of the problem.
  • Used as a workshop tool, the historical profile sets an agenda, helps to focus discussion, provides a simplified method of communication between participants from different disciplines, and stimulates interaction.

In the process of constructing the historical profile, hypotheses or key questions are raised. It also provides a rigorous basis for thinking about possible future developments (or scenarios) that can affect the status of the problem and the ability of those concerned to deal with them.
