Introduction
We have come a long way
since NATURAL CROP PROTECTION was first
published in 1986. The reception given to this book came as a
very pleasant surprise. It was translated into 8 languages and
used primarily as a source book by technical staff, extension
workers and advisors working with small farmers to promote a
more ecological approach to agriculture. The call for
collaboration in that book resulted in a considerable amount of
feedback, much of it from field practitioners. This feedback
has been the main impetus for the current revisions and
additions. This new edition includes updated information on
pests and control, additional pests, and a section containing
case studies of farmer participatory research in natural crop
protection.
While we have come a long way - we still
have a long way to go. In order to help us on our path towards
more natural crop protection, we need to examine
where we are
what has changed and been achieved
who is involved
what remains to be done and
how has it to be done
The context today
Information and communication technologies
are changing our world. They are highly sophisticated and
powerful in their own way and are even influencing the life of
small farmers in developing countries. At the same time,
agriculture is becoming polarized between technology-based
commercialized agriculture and low-technology-based subsistence
agriculture, the latter with a low income potential. Family
members working off-farm often complement the low farm income.
This can result in the feminization of agriculture, where the
women stay back in the rural areas. In many areas women are now
the main food producers (78). It is within this global-local
framework that our support to improving crop protection for
small-scale agriculture has to be seen.
Information and communication technologies
When Natural Crop Production was first
written in the mid-80’s it was difficult to access
information on natural crop protection. This is no longer the
case. Both research institutions and development organizations
have many vehicles for sharing information. Current vehicles
among development actors include newsletters, information and
documentation centres, exchanges between individuals and
organizations and increased access to and understanding of
scientific research findings. Technological communication tools
such as databanks, e-mail and internet now are not only
standard for research institutions but also for many
development organizations. These improved information-gathering
instruments have contributed considerably to make information
more transparent and accessible. However, despite technological
advances in communication technologies, the success of
communicating information depends on making this information
come to life.
Breathing life into information
For information to come to life, it must
first of all be relevant for the receiver, and it must be
perceived as desirable and accessible. For example in a village
in northern Thailand, where neem trees are common, a radio
programme on the utilization of neem was broadcast through
public loudspeakers. The character of the report was academic
and theoretical. The villagers who listened to this programme
did not determine that the information could also be useful to
them, even though there were plenty of neem trees in the
village. It was not perceived as relevant and desirable. The
mindset and language of the report did not act as a
communication bridge between sender and receiver. Providing
access to and breathing life into information can be improved
both through a 'common' language as well as through an approach
which starts with the real situation at the receiver level. In
the case of crop protection, the real situation is the
environment of the farmers, their mindset and knowledge system.
The information only comes to life when farmers use it, by
making it part of their daily work life and decision-making.
In this book, the three information
systems – traditional, local and scientific – have
been treated equally. As much as scientific information needs
to be adapted to local situations, traditional information and
local information need to be verified, understood better and
proven scientifically before being promoted at a larger scale.
In knowledge systems, as in nature, there is no 'either ...
or'. Therefore, when pursuing common goals, it is essential
that we make the different knowledge systems mutually
beneficial.
Research systems
There is both a formal and a non-formal
research system. In developing countries it is often the
non-formal system which achieves major advances improving the
lot of smallholders.
The major players here are governmental
research institutes, universities and international
agricultural research centres (IARCs). These research
institutions pursue a wide range of studies, such as product
evaluation, entomological research, insect ecology, biological
control, natural product research, resistance management,
resistance breeding, Integrated Pest Management (IPM), etc.
Crop protection product development through the formal system
generally pursues the development of new and less toxic
products, often microbial products based on fungi, bacteria,
nematodes or viruses. One important weakness of the formal
research system is that its research depends heavily on
external funding. As a consequence, promising research cannot
be pursued when donor priorities change. This research is often
fragmentary and it is often difficult to link the research
findings of different institutes and combine these into a
larger picture. In addition, even though this research is a
public good, results are not easily accessible. This leads to
under-utilization of existing scientific knowledge which
neither farmers nor the extension system can easily access.
This results, among other factors, to an inadequate quality of
the services of the extension system. These inadequate services
affect particularly small farmers who experience most directly
any lack or inadequacy of the extension services and who have
least access to information.
One of the great contributions of formal
systems towards reducing pesticide use during the past decade
is without doubt the training and extension concept of the
Farmer Field School (FFS) developed by FAO. The FFS is an
experiential learning concept combining defined curricula with
learning exercises and field practices, determined by the
participating farmers and based on their particular interests
and needs. This makes the FFS a flexible concept, which can
accommodate innovative ideas coming from both scientific
research and traditional or local knowledge.
The lack or inadequacy of formal extension
services for small farmers is often compensated for by
non-governmental extension services. During the last decade,
non-governmental organizations (NGOs) have played a vital role
in developing sustainable farming systems and crop protection
practices for smallholders. These have generally not been
addressed by the formal system of research and extension.
Moreover they have developed approaches and methodologies
appropriate for working with smallholders. Well known research
approaches belonging to this category include Rapid Rural
Appraisal / Participatory Rural Appraisal (RRA/PRA),
Participatory Technology Development (PTD) and action research.
Systematic extension models developed by the non-governmental
sector include Farmer–Led Extension and Farmer to Farmer
Exchanges. These approaches are often taken up later by the
formal system.
Furthermore, the non-formal research and
extension system has developed chemical-free farming systems in
crops in which the use of chemical pesticides was previously
considered indispensable. NGOs and innovative farmers have
pioneered the farming systems for organic cash crops such as
cotton, coffee, tea and rice. It is particularly impressive to
see that it is possible to cultivate rice and cotton without
synthetic insecticides, even though cotton accounts for about
20% of all insecticides consumed worldwide.
Cotton (see AfFOResT case study) is a very
good example which demonstrates that:
1. The belief in the indispensability of
chemical pesticides is often based on scientific bias and
vested interests.
2. The development of natural crop
protection concepts requires a holistic approach which combines
natural sciences with economic and social sciences.
3. Non-traditional researchers are capable
of developing successful innovative concepts and techniques
acceptable to small farmers using components of non-formal
research, formal research and local knowledge.
These examples demonstrate that there is a
potential for change, enthusiasm and a will to move ahead.
