New FMD test for cattle
A cheap new test which can distinguish between FMD-infected cattle and
those vaccinated against the disease could help future outbreaks to be
controlled by immunisation according to a German scientist. Unlike existing
tests, the new ELISA (enzyme-linked immunosorbent assay) is fast and low-tech,
explained Armin Saalmuller of the Institute for Immunology of the Federal
Research Centre for Virus Diseases of Animals in Tubingen, Germany.
In the 2001 outbreak of FMD in Britain, vaccination was ruled out because
of the difficulties of distinguishing between vaccinated and infected
animals. Symptoms can take days to develop and during this delay a healthy-looking
animal can spread the disease. The new test can detect the antibodies
that infected cattle produce against the FMD virus which are different
from the antibodies produced by vaccinated animals. Similar tests already
exist, but according to Saalmuller, his version is quicker to use and
is approximately one fifth of the price of tests currently available.
But according to FMD epidemiologist Mark Woolhoouse of the University
of Edinburgh, the test is not sensitive or specific enough. "It's possible
that you'd be using this test on millions of animals. Even if it is 99.9
per cent effective, that means you could misdiagnose a lot of them. Unfortunately
no diagnostic test is perfect," he said.
Unlocking
livestock genome sequence could open doors
An Australian project to unlock the livestock genome sequence, could
provide local industries with an edge over international competition according
to the Commonwealth Scientific and Industrial Research Organisation (CSIRO).
The findings of the Bovine Genome Project (BGP) could also have major
implications for research into the human genome sequence which will be
used to develop new medicines and diagnostic tests. "Currently, the gross
value of livestock-derived products in Australia is approximately AUS$15
billion per annum and the greater part of this comes from cattle and sheep
products. It is a figure anticipated to increase significantly in the
future as a result of sequencing the bovine genome," says CSIRO Livestock
Industries (CLI) chief Sean Coffey.
According to CSIRO, expected benefits include the ability to identify
genes that control growth efficiency, muscle development and milk composition
and the ability to breed disease resistant cattle and sheep. Information
gained about the sequence will be freely available to all interested researchers,
said CLI's Dr Ross Tellam. "The intellectual property rights will be derived
from how we use the sequence, not the sequence itself," he explained.
The project is scheduled for completion by the end of 2005.
Temperate fruit for Ugandan highlands
Uganda has embarked on a USh3 billion (US$1.5m) fruit-growing poverty
alleviation strategy in Kabale district. It comes after recommendations
from the National Research Organisation (NARO) and the World Agroforestry
Centre (ICRAF) who have demonstrated that the production of temperate
fruits is feasible and profitable on smallholder farming systems in the
highlands of Kabale. Nursery demonstration beds have already been started
for the five-year project. The State Minister for Parliamentary Affairs
and district Woman Member of Parliament for Kabale said the outcome of
the five-year programme included the establishment of fruit trees with
the equivalent of 450ha of apples, 40ha of pears, 75ha of peaches and
250ha of plums.
$2m for copperbelt farmers in Zambia
Small-scale farmers and business entrepreneurs in Zambia's beleaguered
Copperbelt region are to benefit from a $2m pledge from the United States
Agency for International Development (USAID). The amount was disclosed
by Cris Muyunda, economic growth deputy team leader at the beginning of
August, during a tour of agricultural and micro-business projects in Central
and Copperbelt regions. Development experts were involved in the initiative
and 120 farmers had already benefited from the project, he said. "The
money is being used to train and expose small-scale farmers to simple
agricultural technology. We are interested in wealth creation through
which sustainable development can be a reality," said Mr Muyunda. USAID
had contracted two American organisations to implement the programmes.
'Input
shortage threatens food security in Zimbabwe'
A shortage of inputs and inflation is impeding agricultural recovery
in Zimbabwe, according to the Zimbabwe Farmer's Union. The country is
once again badly affected by food insecurity as a result of erratic weather,
the effect of the government's fast-track land reform on commercial agriculture
and the impact of HIV/AIDS. Aid agencies estimate some five million Zimbabweans
will require food aid by January 2004; moves by the Zimbabwean government
to control distribution have also raised fears that food aid could be
denied to opposition supporters.
"If farmers are provided inputs on time - given that the forecast is
for normal to above normal rainfall this season - there should be agricultural
recovery," said chief economist of the ZFU, Tafireyi Chamboko. However,
there's a shortage of some the inputs, he explained. New farmers are being
supplied with inputs such as fertiliser and seed through an inputs credit
scheme, but others are facing major problems. "It is a major constraint,"
he said. "Fertiliser is in short supply and it's quite expensive, given
our inflationary environment. The major factor impacting on farmers is
the price of inputs - our inflation rate is now 364.5 per cent - so we
have a question of shortages, compounded by the fact that companies that
produce fertilisers are faced with a shortage of foreign currency to buy
the raw materials they need."
Turkmenistan water project criticised by
environmentalists
Plans for a giant artificial lake in Turkmenistan, which was expected
to create 4000sq km of farmland capable of producing 450,000million tonnes
of cotton and 300,000million tonnes of grain a year, have been criticised
by environmentalists. "The lake could pollute massive swathes of land
with salt and most of the water would evaporate from an open-air lake
anyway," said Michael Wilson of the EU's Tacis support programme. The
intended project would cost about $4.5billion and be completed within
20 years. Those supporting the project believe it would provide sufficient
water for Turkmenistan's growing population and for agriculture, and would
reduce the country's dependence on the Amudar'ya River (which it shares
with neighbours Uzbekistan, Afganistan and Tajikistan). Uzbek scientists
are also voicing concerns over the environmental effects of the lake and
are worried over its effects on local water supplies.
Global think tank for world food needs
A coalition of organisations ranging from international agencies to farmers
rights groups are to participate in the largest-ever global dialogue on
how to meet the world's future food needs. At a meeting in Budapest at
the beginning of August, representatives of such organisations committed
to taking part in a 30 month review of how science and technology can
be used to increase food production in socially acceptable and environmentally
sustainable ways. The review is estimated to cost US$15m to prepare and
is planned to be carried out by an intergovernmental body administered
by a multi-stakeholder bureau. Planning is being co-ordinated by Robert
Watson, the chief scientist at the World Bank. Funding is now being sought
from the World Bank and UN agencies and, according to Watson, if fundraising
is successful the review could start early next year. "Our goal is develop
a consensus on what is known and unknown, explain different points of
view, and identify the uncertainties," says Watson.
