About this report
The 2012-13 Annual Research Achievements Report provides a summary of research and development activities in primary industries in the Northern Territory (NT) (excluding fisheries for which there is a separate annual report series titled Fisheries Status Reports 2012) by the Department of Primary Industry and Fisheries (DPIF). The report covers current and recently completed research in the pastoral, plant industry and biosecurity sectors. The report highlights the effort of DPIF researchers through which services are provided to primary producers to improve their productivity and profitability and to control animal and plant diseases.
DPIF’s Industry Development Plan 2013-17 focuses on profitable and productive primary industries, highlighting the following emerging challenges for research and development among others: provide certainty and security to encourage investment, facilitate continuous improvement in production quantity and quality, expand market options for Territory products, develop and promote a more efficient and environmentally sound production system, promote biosecurity and encourage Indigenous participation. Each research project in this report addresses at least one of these challenges.
Primary industry activities in the NT focus mainly on pastoral, crop and horticultural production. Products include beef cattle, buffalo, crocodiles, field crops, pasture, hay, seeds, forestry products, mangoes, melons, vegetables and cut-flowers.
The primary industry sector in the NT has significant links with other sectors of the local economy and contributes to manufacturing, transport, storage and retail, thereby enhancing employment.
Comments and suggestions for improvements of future editions of this report, including content, layout and structure, are most welcome. Please send your comments and suggestions to firstname.lastname@example.org.
