Be it environmental, climatic, diversity of enterprises, valley floors to high country, dryland to inten- sive irrigation, old ways and new technology, extremes in all these things are present within our region, but also between us and the rest of the country. Back at the last conference here in 1986, land use change was a hot topic and is prominent again this time round. Not so much focus now on tenure review when compared to the massive rise of the dairy industry, irrigation and Lucerne grazing systems. Tourism was identified back then as a great opportunity and is a major regional industry today, question is where to next? Current hot topics are irrigation; nutrient management; dryland pasture options and hill country development - all have relevance to the three properties we are visiting. I would like to thank the owners and managers of the properties we are visiting for allowing us the opportunity to look inside their businesses and their assistance in compiling the information in this programme. Thanks to Green- field NZ Pastures Ltd, Ida Valley Station and Nine Mile Pastoral Ltd. I would also like to thank the members of the Local Organising Committee for being a great team and doing such an awesome job bringing this conference together. We hope you have a great time, learn heaps and leave happy having spent a few days in our World of Difference. Best Wishes Vanessa Hore Chair, Conference Organising Committee 4 INFORMATION FOR DELEGATES the conference organisers no responsibility will be accepted for any losses incurred.
