Low-Cost
Water Pumps To Boost Food Security

- In a region where engine-driven irrigation pumps are unaffordable
for small-scale farmers, food security in Africa could be boosted
by an increased use of locally produced low-cost water pumps, a
UN Food and Agriculture Organisation (FAO) report said..
Currently,
most irrigation equipment in sub-Saharan Africa is imported. In
most cases the equipment is beyond the reach of poor farmers and
often inappropriate for use by small-scale farmers. According to
the report, titled 'Treadle pumps for irrigation in Africa', only
four per cent of arable land is under irrigation in sub-Saharan
Africa. This compares to 24 per cent in Northern Africa, 37 per
cent in Asia and 15 per cent in Latin America.
The
lack of proper irrigation schemes is contributing to the region's
food insecurity. FAO estimates the number of chronically undernourished
and hungry people in sub-Saharan Africa at 185.9 million or 34 per
cent of the population.
In
southern Sudan, more than three million people are facing serious
food shortages due to ongoing civil conflict and an emerging drought,
a recent joint report issued by FAO and the World Food Programme
(WFP) noted.
Nearly
two million people have died in Sudan's civil war and related famines
since May 1983.
In
Ethiopia, some 6.2 million peasants, hit by drought, need food aid.
Ethiopia has appealed for 470,000 metric tonnes of food aid and
21.4 million dollars to feed starving population this year.
According
to the 2000 "State of food insecurity in the world", 826
million people around the world do not get enough to eat -- 792
million people in developing countries and another 34 million in
industrialised countries and countries in transition.
Despite
pledges made at the 1996 World Food Summit to reduce by half the
number of hungry people in the world by 2015, the situation is not
improving.
Part
of the reason could be that many African farmers are still using
bucket-lifting technologies, which are slow, cumbersome and labour
intensive to irrigate very small plots of land, FAO said. Water
lifting rates are only between 0.5 and one cubic metre per hour.
Treadle
pumps, noted for their user-friendliness, can be used in a comfortable
way, the farmer stands on the treadles, pressing the pistons up
and down, lifting up to five cubic metres per hour.
''Small-scale
irrigation is seen as one of the success stories in many countries
in Africa, at a time when large-scale developments have failed to
come up to expectations,'' the report noted.
''It
is usually developed privately by farmers in response to family
and local market requirements, without the need for government interventions.
This has been at the heart of its success,'' the report added.
Case
studies from Kenya, Niger, Zambia and Zimbabwe show that by using
treadle pumps farmers could increase irrigated land, reduce work
time compared to bucket irrigation, improve crop quality, grow new
crops and increase the number of cropping cycles.
In
Zambia, FAO's Special Programme for Food Security, now operational
in more than 60 countries, has contributed considerably to the use
of small pumps. Around 200 treadle pumps have been installed on
demonstration sites. This has contributed to a wider adoption of
pumps in Zambia. The economic benefits of small pumps have been
significant for farmers.
In
Zambia, incomes have risen more than six-fold from 125 dollars achieved
with bucket irrigation on 0.25 hectare of land to between 850 and
1,700 dollars using treadle pumps.
In
some cases cropping intensity could be extended to three crops per
year. In Zimbabwe, treadle pumps are mostly used for irrigation
of small vegetable gardens. As a result, family nutrition has improved
in most areas.
Another
advantage of treadle pumps is that they do not contribute to the
depletion of valuable ground water resources, according to the FAO
report. In general, these pumps can only reach shallow ground water
resources within six metres.
''The
costs of buying, running and maintaining engine-driven irrigation
pumps are too high for many small farmers in developing countries,''
said Tom Brabben of the International Programme for Technology and
Research in Irrigation and Drainage, sponsored by FAO and the World
Bank.
''Treadle
pumps are cheaper and easier to handle, they can contribute to higher
food production and create employment and income if pumps are produced
locally,'' he said. ''For poor farmers this is a viable first step
towards irrigated agriculture.'' ''If we want to achieve 'more crop
per drop' in Africa, small water pumps that fit into the social
and economic environment, will have to play a bigger role,'' Brabben
said.(END/IPS)
