Wise use of resources means using them sustainably for the greatest good. Many dairy farmers have planted riparian zones of native vegetation on their farms to protect sensitive waterways and wetlands. National prosperity New Zealand ranks as the fifth most prosperous nation in the world according to the 2013 Legatum Prosperity Index. For many years, dairy farming has been a key driver of the New Zealand economy – contributing to more than 25 per cent of export earnings. There is still considerable scope for dairying to contribute more to the economy through increased production, higher value milk, and value-added dairy processing. However, New Zealanders have made it clear in recent times that such growth must be achieved responsibly and not, for example, at the expense of the environment. Collectively, the dairy farming industry contributes substantially to New Zealand’s economic prosperity. This is highlighted in the following statistics: Over $13 billion in dairy exports in 2012, the largest of any goods sector and more than 25 per cent of total goods exports $5 billion contribution to national Gross Domestic Product (GDP), more than a third of the entire primary sector Employs approximately 45 000 people including approximately 10 000 self-employed. Sustainable dairying Dairy farming needs to be seen to work for all New Zealanders. Dairy farming needs to be both competitive and responsible. This means being competitive in a local and global sense – and responsible today and tomorrow. This responsibility is particularly important with regard to the natural environment. The Water Accord The purpose of this accord is to enhance the overall performance of dairy farming as it affects freshwater by: Committing to good management practices expected of all dairy farmers in New Zealand. Recording pledges by the dairy sector, with the support of others, to assist and encourage dairy farmers to adopt those good management practices and to monitor and report progress. Riparian zone with some evidence of planting 3 Riparian management expectations Dairy farms will exclude dairy cattle from significant waterways and significant wetlands using fencing. Riparian planting will occur where it would provide a water quality benefit. The crossing of waterways by dairy cows will not result in degradation of those waterways. Cross-section of planted riparian zone that is protected from dairy cows by fencing Dairy companies will: Implement measures to exclude dairy cattle from waterways and drains greater than one metre in width and deeper than 30 cm and significant wetlands on dairy farms according to the phase-in timetable between May 2014 and May 2017. Encourage dairy farmers to exclude dairy cattle from all wetlands and apply the stock exclusion commitment to third party grazing land as if it were their own land. Implement measures to ensure 100 per cent of regular stock crossing points are either bridged or culverted by 31 May 2018. Introduce measures to achieve progressive riparian planting of the length of waterways within or bounding dairy farms from which there is stock exclusion, where riparian planting will contribute to water quality enhancement according to the phase-in schedule of riparian management plans between 2014 and 2030. Promote and facilitate (including through partnerships with other organisations) riparian planting to enhance ecosystem health (ongoing). Nutrient management Dairy farmers will manage nitrogen (N) and phosphorus (P) loss from dairy farming systems, acknowledge the need to manage within nutrient loss limits and pursue continuous improvement in nutrient use efficiency. DairyNZ will develop an audited nitrogen management system that will enable dairy companies to model nitrogen loss on supplier dairy farms in a robust manner according to agreed protocols and consistent data collection systems. Effluent management expectations Dairy farms will comply with regional council effluent management rules and/or resource consent conditions. Effluent systems installed on dairy farms will be fit for purpose and able to achieve 365-day compliance with applicable rules. Introduce programmes to reduce reliance on discharges to water from two-pond Farm Dairy Effluent (FDE) treatment systems in areas where land application would result in improved 4 water quality outcomes by 31 May 2014. Looking ahead The following diagram showing dairy industry objectives provides a broader view of making dairy farming work for everyone as we go forward: Achievements In accordance with the original 2003 Clean Streams Accord, dairy cattle are now excluded from 87 per cent of streams, rivers and lakes. Ninety-nine per cent of race crossings now have bridges or culverts. Ninety-nine per cent of dairy farms have nutrient budgets in place, and 56 per cent have nutrient management plans. A warrant-of-fitness system for dairy effluent management systems has been developed, with training and accreditation systems for rural professionals to support farmers’ management of dairy effluent. Dairy farm effluent non-compliance is less than 10 per cent nationally. Research for reducing greenhouse gas emissions from housed wintering systems has been completed as the basis for a good practice guide. Dairy companies are implementing supplier agreements aligned with achieving sustainable dairying (e.g. Fonterra’s Supply Fonterra and Synlait’s Lead with Pride internationally accredited dairy farm assurance). 5 Source (adapted) and images: Strategy for Sustainable Dairy Farming and Sustainable Dairying: Water Accord. http://www.dairynz.co.nz 6 Resource B: Habitat restoration – Whau River The Whau River, its streams and surrounding environment is an example of how urban waterways can become degraded by human activity. Fifty years ago, the river and its streams teemed with fish, played host to migratory birds that fed and roosted there, and its banks were covered in native vegetation. Now this city landscape in Auckland is in trouble. Cultural perspectives on habitat restoration The streams and creeks that flow into the Whau have been important to Māori for centuries. Te Whau, the Māori name for the tidal stream flowing into the Waitemata Habour, provided access between the Waitemata and Manukau harbours, and the forests that existed in this area provided the trees from which local Māori built their canoes. Māori view water and other natural resources as taonga (treasure) with spiritual and metaphysical properties. These properties, both practical and spiritual, are bound together within the mauri (life-force) that empowers all living things, makes people a part of the natural world, and is central to the mana and lifeblood of iwi, hapū, and whānau. When Pākehā talk about restoring the health of streams and rivers they often talk in terms of ecological health. In Māori terms, this is expressed as restoring the mauri. Both viewpoints serve to protect our streams and rivers. Settlement of the Whau area The impact of population growth has seriously affected the health of the river. In 1890 there were only 29 buildings in New Lynn, a suburb bordering on the Whau River in the north, and most of the surrounding area was farmland. However, the expansion of the rail network and New Lynn’s development as an industrial centre kick-started a population growth which continues today. There are more than 64,000 people living in the Whau catchment area and this figure will probably double within the next 20 years. We can no longer swim in, fish, or enjoy many parts of the river the way we used to. As more people have moved into the area, fewer native plants and animals are found in or around the area. For many locals the river has become the “dirty old Whau” and its streams “grotty” patches of water they try to ignore in their backyard. Pollution and the Whau Most of the pollution that enters the Whau does so through stormwater. With development there is less land for rain to permeate, so excess water becomes stormwater run-off. Automobiles are responsible for heavy metals such as copper, lead, and zinc which are derived from petroleum-based products. Heavy metals come off tyres, brakes, engines, oils, rust and exhaust fumes. As soon as it rains, they are washed off the roads and straight into the waterways. Housing development along banks of the Whau River 7 Sediment, or silt, comes from cleared ground, erosion, landslides and building sites. Sediment smothers creatures and affects the light source that plants need to grow. In high concentrations sediment can: irritate gills of fish bury and suffocate fish eggs dislodge plants, invertebrates and insects in the stream bed, reducing the food sources of fish. The early stages of development such as excavation for new subdivisions contribute the biggest source of sediment. Sediment run-off is a natural process, even from stable native forests, but human activity in the area dramatically increases the amount of sediment produced. Oils, paints, detergents and other chemicals Paints have many ingredients that are dangerous to stream and river life, such as lead, zinc, cadmium, chromium and mercury. Detergents used in car washes add phosphates and nitrates that use up lots of oxygen as they biodegrade. Even biodegradable products can pollute waterways and take the oxygen out of the water as they biodegrade. Oils coat the surface, stopping oxygen getting into the water. Without this oxygen the fish suffocate. Looking to the future One way to create a healthy ecosystem is by replanting appropriate native vegetation alongside streams and riverbanks. A continuous edge of overhanging plants from long grasses and trees form shade which keeps the water cool for stream life. Stable banks planted with appropriate vegetation bind the soil and minimise run-off. A buffer zone of native vegetation each side of the riverbank provides a habitat for birds, lizards, and other wildlife. Residents with houses neighbouring the streams and river have the most to gain by caring for the streambanks and can do a lot to help. Cleaning up the Whau not only improves property values but makes its streams an asset and not a liability. Quality of life is improved now and in the future if the river is safer and healthier. However, if we are serious about protecting the Whau then both individual and community action is needed. The task is easier with others and we can invite our neighbours, families and friends to get involved in cleaning up the Whau. We need leaders – people to develop the vision Riparian zone planting along banks of the Whau River of how healthy our streams and river could be – to stand up and excite others with that vision. Some Whau residents are already taking action by joining the Friends of the Whau community group and taking part in initiatives like Wai Care. It is impossible for us to turn back the clock completely. It is unrealistic to think we can have absolutely pure waterways when cities and industries have been built on their banks. However, it is possible to safeguard what we have left by not making the problem worse and by working individually and communally alongside our local and regional councils to improve our water quality and ensure the Whau retains its mauri/life-force. 8 Source (adapted) and images: The Whau, our streams, our river, our backyards. http://www.waitakere.govt.nz/abtcit/ei/pdfs/environment/thewhau.pdf 9 Resource C: Sustainable fishing New Zealand’s oceans New Zealand has one of the largest marine areas in the world, covering more than 1 per cent of the Earth’s surface and 23 times our land area. The marine areas of the New Zealand Exclusive Economic Zone (EEZ) and extended continental shelf are incredibly diverse. They range from the subtropical oceans in the north, to temperate waters around the mainland and cool subantarctic waters in the south. Many of our marine species are found nowhere else in the world. Scientists estimate that more than 80 per cent of New Zealand’s biodiversity is found in our oceans and much more is yet to be discovered. About 17 135 marine species are known from New Zealand including some 4315 undescribed species in collections. The total number of species in the New Zealand marine environment could be well over 100 000 species. Our marine area is also a vital part of our economy, supporting our $1.5 billion fishing industry and our $20 billion tourism industry. Royal albatross on the South Pacific Ocean near Dunedin It is also central to our national identity: most New Zealanders live near the ocean and have a close relationship with the marine environment. We collect kiamoana (seafood), swim, surf, dive, snorkel and sail, and appreciate the variety of life in our marine environment. New Zealand currently has 34 marine reserves (no-take areas), yet less than 1 per cent of New Zealand’s marine environment is fully protected. Oceans under threat New Zealand’s marine environment is under increasing pressure from human activities. Climate change, pollution, coastal development, mineral exploration and mining create cumulative effects that are having a detrimental impact on the health of the marine environment and marine life. Fishing operations have the most significant impact on the marine environment, both through the amount of fish caught and the methods used to catch it. Some fishing practices, such as bottom trawling and dredging, used by fisheries in New Zealand waters damage the marine environment. Over the last 50 years, fishing technologies have developed to such an extent that the scale of fishing operations now exceeds a level that is sustainable. The United Nations estimates that 70 per cent of the world’s fisheries are now exploited to their limits, over-exploited or depleted. 10 Many fishing operations result in significant levels of bycatch – species such as albatrosses, dolphins, sea lions and other non-target species. According to Statistics New Zealand, fishing uses more energy as a proportion of total costs than any other industry sector, increasing by 40 per cent in the last decade in terms of environmental cost. New Zealand prides itself on our clean, green image and promotes its fisheries management as world-leading. Compared to some fisheries, this is partly true – New Zealand does take a comprehensive management approach that is recognised as being among the best. But comparing ourselves to countries with no or very poor fisheries management does not mean that we New Zealand sea lion mother and pup on Otago Peninsula should be proud of our situation. New Zealand is still far from living up to its slogan “If it’s from New Zealand, it’s sustainable.” Fisheries for wild species typically take place in open waters, with low levels of enforcement of rules that aim to ensure sustainability and few observers to report any breaches or problems. New Zealand’s fisheries quota management system (QMS) is a rights-based system that entitles quota holders to a ‘right to fish’, which encourages them to fish to the maximum level allowed under their quota, rather than take a more sustainable approach. To ensure sustainability, the QMS requires good information and a precautionary approach. Fisheries management in New Zealand is failing by: Allowing significant waste of fisheries resources. Having no upper size limit and allowing fish that have gathered to spawn to be caught, reducing the ability of fish populations to reproduce. Targeting the maximum (rather than an optimum or precautionary) yield. Lacking information about fish stocks and how sustainable catches are. Allowing or poorly managing levels of marine mammal and seabird deaths, including endangered species. Using destructive fishing techniques, such as bottom trawling and dredging, which destroy habitats and seabed life. 11 Our vision Forest & Bird has a vision for a more sustainable fishery by 2030: A healthy and diverse marine environment supporting an abundance of marine life, where profitable fisheries operate alongside other activities. Adverse impacts of fishing on the marine environment have been minimised or mitigated, and ‘nursery areas’ – important for replenishment of populations – are fully protected within marine reserves. New Zealand meets or exceeds the world’s best practice in fisheries management and environmental practice, so it can market truly sustainable products worldwide. Forest & Bird hopes that making seafood consumers aware of the problems behind our fisheries management will help them make better choices and encourage our fisheries to improve their practices.
