AN extra $264 million will be needed to implement the Government's Livestock Waste Control Programme. Officials hope that by boosting grants and loans to farmers, only 15 per cent will still be in the livestock business at the end of the 10-year programme, now estimated to cost $1.35 billion. The proposal to raise the grants were put forward by the Director of Agriculture and Fisheries following a review of the scheme. The grants are to cover half the capital costs for installing treatment facilities but farmers complain the rates are not enough. Ex-gratia payments are paid to ease the financial hardship of farmers who have opted out. While previous government calculations estimated that 20 per cent of farmers would opt for capital grants and the rest for ex-gratia allowances, many had stayed in business and only four per cent had opted for capital grants. Under the revised funding proposals to be presented to the Legislative Council for approval, the biggest jump in estimated expenditure is the ex-gratia allowances, up by 27 per cent to $790.9 million. Capital grants would increase by 85 per cent to $114.8 million while loans used to complement the capital grants will rise by 72 per cent to $80.5 million. The amount is based on estimates by the Agriculture and Fisheries Department that about 1,300 livestock farmers will stay in business.
