Some common questions about participatory research: a review of the literature
Nina Lilja and Mauricio Bellon
This article reviews, through reference to the published literature, some key questions about participatory research. When should participatory research be used? How should participatory research be applied? What about quality of science in participatory research? Are there any institutional issues associated with the use of participatory research? And what are the benefits and costs of participatory research? The article is not a comprehensive literature review on participatory research, it is not meant to set standards for participatory research, nor to define what constitutes ‘good’ participatory research, but rather it seeks to summarise the realities of implementing participatory research, as discussed and debated by several published authors, and to provide some useful background for this special issue.
This article1 reviews some overarching questions concerning participatory research that should ideally be answered before embarking upon a new research project (even better, before or during the planning of the project). These basic questions are addressed by reference to the literature. An earlier version of this article was used to identify key elements to be considered in a review of the status of participatory research at the International Maize and Wheat Improvement Center (CIMMYT) (Lilja and Bellon 2006), and was used to develop the survey questions for researchers. It is not, therefore, a complete review of the rationale for participatory research or its impacts.
The objective of participatory research
Conventional research tends to package intervention methods and programmes into one-size-fits-all, off-the-shelf approaches, based on a notion of universal best practices. Participatory methods address the drawbacks inherent in that approach by actively involving end-users in the research process, incorporating their views and representation into the prioritisation, review, conduct, and dissemination of scientific research. This fosters trust in agricultural research, increases research participation, addresses issues of greatest importance to the communities, and aids the translation of research results into useful practice.
Participatory research gives rural people within a study population opportunities to determine what is being studied, and teaches them the basics of research methodology so that they can assume collaborative roles. Furthermore, many if not most rural people in developing countries operate in imperfect markets, where prices do not completely reflect the value that these people attach to the activities that they engage in or goods that they consume or produce; therefore, simple profitability analyses — which may work well under the conditions of good market development that are common in developed countries — may be a poor guide to decision making about new activities, technologies, and products intended to improve the livelihoods of people in developing countries. Participatory research can provide a more accurate assessment of what people value that is not completely captured by market prices; this information in turn, if fed back into the design and development of new technologies, should help to make such new technologies more relevant and appropriate, so that they generate more benefits for these people. In practice, participatory approaches engage people in a community in some or all aspects of the research process — determining research questions, developing technical solutions and approaches to obtain information, and deciding what the research means and how it should be used to benefit the community.
There are two types of literature, one about types of participatory research (see, for example, Biggs 1989; Biggs and Farrington 1991; Pretty 1994), and other studies which focus on describing participatory tools and how to use them (for example, Farrington 1988; Chambers et al. 1989; Okali et al. 1994; Chambers 1997; Campbell 2001). However, there are no specific standards set for participatory research to guide research managers in monitoring what constitutes ‘good’ participatory research, or to help them to decide when participatory approaches would be more effective than conventional research methods, and hence to decide when their impact, via the products of the agricultural research process, on the lives of the intended beneficiaries (mostly farmers) would be more effective than that of conventional research methods.
When should participatory research be used?
Studies claim that participatory approaches are crucial in programmes that require holistic approaches (rather than changing one technology at a time), and where environmental and socio-economic conditions vary widely among farmers and sites (Roling and Wagemakers 1998). However, very few published studies provide definite decision rules based on empirical evidence for research management about when participatory approaches are most beneficial to technology development, compared with traditional centralised approaches (typically based on on-station technology development and on-farm testing). Some studies show that the traditional scientist-designed and -directed agricultural research programmes are very effective at developing varieties and technologies that can be used in farming systems that are fairly homogeneous, but often less effective when the reality of the farmer is more complex and risk-prone (Byerlee and Heisey 1996; Ohemke and Crawford 1996; Maredia et al. 1998; Evenson and Gollin 2002; Dalton and Guei 2003).
In reality, participatory approaches are often tried and used after the failure of conventional approaches to developing and delivering improved crop types and natural-resource management (NRM) techniques to resource-poor farmers. There are various reasons for the low uptake of agricultural technologies produced by formal research systems. Nowak (1992) defines two types of barrier to adoption: the inability to adopt, and the unwillingness to adopt. Inability to adopt includes situations where information about the technology is lacking; the cost of obtaining the information about it is too high; the technology is too complex or too expensive; the technology has excessive labour requirements; benefits are too far in the future; farmers have limited access to resources that might support them; managerial skills are inadequate; and farmers have no control over the adoption decision. The farmers’ apparent unwillingness to adopt can be due to the fact that conflicting or inconsistent information is provided about the new technology; the information about the technology is difficult to apply in a farmer’s particular circumstances or is irrelevant to those circumstances; there is a conflict between the current production goal and the new technology; the technology is inappropriate for the individual’s physical setting; or there is an increased risk of negative outcomes. Ignorance on the part of the farmer or technology promoter, and belief in traditional practices, can also result in farmers’ unwillingness to adopt new technology.
There are several studies that provide some insight into the question of when it is best to use participatory research approaches. Weltzein et al. (2000) use a matrix of two parameters (biophysical and economic environment) to map 65 participatory plant-breeding projects. Their biophysical environment scale ranges from high to low stress, based on actual versus expected yields, coupled with an index for incidence of crop failure. Their economic environment parameter ranges from high degree of homogeneous demand to heterogeneous demand (for instance, high-input commercial crops to low-input subsistence crops). The projects in the sample were widely dispersed within the matrix. Although many plant breeders consider participatory approaches most appropriate for environments that are high-stress and where few inputs are used (subsistence agriculture), a large number of sampled projects were located in the intermediate areas where agro-climatic stress was less severe.
Johnson et al. (2004) surveyed 59 participatory NRM projects, among which the most common resource across all projects was soils — nearly half of the projects worked on soil-related topics. Water was the second most common resource, followed by forests and biodiversity. The priority given to different resources varied across geographical regions. Institutional innovations were the most common technology on which projects reported working, followed by agronomic practices in Africa, and agro-forestry in Asia and Latin America. Half of the projects in the study reported working on more than one resource or technology. The average project in ...
