Over the coming planning period we will see a number of deliverables in this area, and I'll list a number of examples: completion and publication of a report on the health of our atmosphere—this is a companion report to one you've seen before called Health of our Soils; transfer of the Plant Gene Resources Centre to Saskatoon; registration of a high-protein soybean variety for eastern Canada with significant yield to improvement; registration of prairie spring wheat with significant improvement in protein content; development of new anaerobic digestion technology to handle manure in an environmentally sustainable manner; development ...[+++] of technologies to improve ruminant nutrition—this again has efficiency and waste reduction objectives; development of processes for extracting food or feed additives from various agricultural products; increased access to safe, reliable water supplies for rural areas; maintenance of biological diversity through sustainable management of federally controlled and private range lands; development of a prairie-wide assessment for land-based issues facing the agriculture and agrifood sector; implementation of the national soil and water conservation program; implementation of Agriculture and Agri-Food Canada's biodiversity strategy; determination of the environmental sustainability of the departmental policies and programs; periodic assessment and reporting of the progress in implementing the department's sustainable development strategy, which is essentially the implementation of the action plan under that strategy; and development and implementation of the department's hog environmental management strategy, HEMS.
