The Development of IPM Training in Asia

Almost one third of the world’s population consists of Asian farming households. Among developing countries in the region, the proportion of the population engaged in agriculture lies between 42% in Indonesia and 96% in Nepal. Most of these farming families are small holders. In Vietnam for example, the share of small holders in the total population is 60%.   These small farmers are the bedrock of Asian economic development.

Three decades ago, an immense social and economic experiment was launched in Asia. The experiment, which has subsequently come to be known as The Green Revolution, was largely based on an ‘engineering’ approach to smallholder agriculture.  Agricultural productivity could be raised by making certain inputs more readily available to small farmers was the main assumption of the approach. This approach was most successful where there:

was enhanced access to water;

were improved varieties of new rice, wheat, and corn varieties made available;

was increased availability of inorganic fertilisers.

Small farmers, particularly those located in well-irrigated areas with good soils, responded positively to the opportunities that easier access to these inputs presented. Farm productivity increased substantially.  The average rice yields in the region doubled between the 1960’s and the 1990’s.

Helping small farmers to build sustainable, productive agricultural systems proved more difficult than was originally supposed. Green Revolution programmes were designed to disseminate new technologies as quickly as possible. Because of the tremendous number of small farmers in most Asian developing countries, the dissemination process was greatly simplified to facilitate rapid adoption of new inputs and methods. Agricultural development programmes came to rely on highly centralised systems designed to deliver input packages and information to small farmers. Although this approach succeeded in introducing small farmers to the new inputs, new problems quickly emerged.  

The centralised systems were unable to take into account the reality of pronounced agro-ecological diversity within countries, regions, and even within villages. The inclusion of routine pesticide applications within the input packages often caused severe ecological disruptions, most notably the rise of pest resurgence and resistance. Rather than reducing production risks for small farmers, the input packages frequently generated new, more serious threats to the sustainability and profitability of small-scale cultivation. Together with this disruption of the ecosystem came new threats to farmer health and the introduction of millions of tons of poisonous substances to the fields, waterways, food, and homes of rural people.

The inability of Green Revolution programmes to tailor input use to local conditions extended beyond pesticides to inorganic fertilisers and seeds. Centrally-designed nutrient packages needed to be adjusted to field-specific soil conditions. The top-down extension of these packages did not give farmers the knowledge they needed to make these adjustments. Improved varieties were also introduced uniformly without assessing local needs and conditions.  In many regions production risks were often actually increased while local biological diversity was dangerously reduced.   As a result, variation in yields increased in step with average yields and the marginal productivity of physical inputs began a long downward trend. More and more inputs were needed to achieve ever smaller incremental increases in production per unit area.

Of equal, if not greater importance, were the social implications of the engineering approach to farming systems. The government agencies that sprang up to disseminate Green Revolution technologies were target oriented and often rigid in their interpretation of their mission. The pressure which these agencies put on small farmers to use inputs in accordance with centrally-determined recommendations contributed to a ‘de-skilling’ of rural communities. Farmers were expected to be passive recipients of new technologies rather than active innovators.

IPM and Sustainable Development

During the 1970’s and 1980’s, it became increasingly apparent that pest resurgence and resistance caused by the indiscriminate use of insecticides posed an immediate threat to the gains of the Green Revolution. At the same time, research was being conducted which demonstrated the viability of biological control of major rice pests. Gaps still existed, however, between the science generated in research institutions and common farmer practice conditioned by years of aggressive promotion of pesticide use.

Over the ensuing years, a number of approaches were tried to bring IPM methods to small farmers - particularly rice farmers - in Asia.  These approaches had mixed results. Many experts claimed that the principles of IPM were too complex for small farmers to master.  These people maintained that centrally designed messages were still the only way to convince farmers to change their practices.

By the end of the 1980s, however, a new concept emerged in Southeast Asia. This concept held that the problem was not farmers themselves, but rather the methods used to disseminate technological packages among farm communities.  These methods were technologically driven, not farmer driven.  Given appropriate training methods that would empower farmers through learning, farmers could:

master the ecological principles needed to implement IPM in their fields;

become expert in IPM;

apply what they have learned to develop new initiatives and gain greater control over the conditions which they face.

IPM Farmer Field Schools (FFS) were first carried out in Indonesia, and later extended to other countries in the region. Field Schools give small farmers practical experience in agro-ecosystem analysis, providing the tools they need to practice IPM in their own fields. FFS also provide a natural starting point for farmer innovation covering the whole range of issues relating to crop management, from insect balance to plant health, from soils to water control and from weed management to varietal selection.

The success of IPM FFS has opened up a new approach to the development of sustainable, small-scale agricultural systems. Farmers, having demonstrated their enthusiasm for learning and applying ecological principles, have pointed the way forward to a future when they will no longer be viewed as passive recipients of recommendations generated in far-off research laboratories. Farmers have shown that the managerial necessity of taking local biological diversity seriously is matched by an intellectual curiosity to understand the ecological process and eagerness to formulate community-wide approaches to agricultural development.

Towards Community IPM

The central lesson of programme implementation over the past decade is that the complex ecological and social context of IPM argues for a sustained effort combining elements of technological development, adult education, local organisation, alliance building and lobbying. Scientific excellence and adherence to ecological principles provide a strong technical basis for IPM development, and the application of participatory, non-formal adult education methods represent a real advance over models based on information dissemination and the delivery of simple messages. But these in themselves are not enough. The long-term development of a sustainable small-scale agriculture also requires strong farmer groups and the linkages between these groups and the wider community.

From this perspective, IPM Farmer Fields Schools are not an end in themselves, but rather a good starting point for the development of a sustainable agricultural system in a given locality. The FFS provide a first experience with experimentation based on ecological principles, participatory training and non-formal education methods. Once this foundation has been laid, farmers are better able to act on their own initiatives, and to sharpen their observation, research and communicative skills. Thus the Farmer Field School sets in motion a longer-term process, in which opportunities are created for local leadership to emerge and for new, locally devised strategies to be tested.
