This paper examines the potential for phosphorus (P) release from intensively grazed pasture to waterways. In particular it describes the P release processes occurring in riparian buffer strips. Soil samples at three depths (0 2.5, 2.5 7.5, and 7.5 15 cm) were collected from riparian buffer strips, including wetland and non?riparian areas at three pasture sites. These soil samples were analysed for total P, plant available P as measured by Olsen P, and soil solution P as measured by 0.01M CaCl2?extractable P.
In the absence of clear international policy signals and strong global agreements on climate change and sustainable agriculture, countries are moving forward to test sustainability strategies through innovative policies and financing programmes. This paper explores how three countries – Brazil, Ethiopia, and New Zealand – are using integrated policy approaches to address the linked challenges of climate change, unsustainable agriculture, and food insecurity.
In 1990, Australia and New Zealand were ranked around 25th and 37th in terms of Gross National Product (GNP) per capita, having been the highest-income countries in the world one hundred years earlier. Those countries relatively poor economic growth performance over that long period contrasts markedly with that of the past 15 years, when these two economies out-performed most other high-income countries. This difference in growth performance is due to major economic policy reforms during the past two to three decades, both at and behind the border.
Doing business sheds light on how easy or difficult it is for a local entrepreneur to open and run a small to medium-size business when complying with relevant regulations. It measures and tracks changes in regulations affecting 10 areas in the life cycle of a business: starting a business, dealing with construction permits, getting electricity, registering property, getting credit, protecting investors, paying taxes, trading across borders, enforcing contracts and resolving insolvency.
This tenth edition of Doing Business sheds light on how easy or difficult it is for a local entrepreneur to open and run a small to medium-size business when complying with relevant regulations. It measures and tracks changes in regulations affecting eleven areas in the life cycle of a business: starting a business, dealing with construction permits, getting electricity, registering property, getting credit, protecting investors, paying taxes, trading across borders, enforcing contracts, resolving insolvency and employing workers.
To meet carbon emissions targets, more than 30 countries have committed to boosting production of renewable resources from biological materials andconvert them into products such as food, animal feedand bioenergy. In a post-fossil-fuel world, an increasingproportion of chemicals, plastics, textiles, fuels and electricity will have to come from biomass, which takesup land. To maintain current consumption trends theworld will also need to produce 50–70 percent more foodby 2050, increasingly under drought conditions and onpoor soils.
The effectiveness of biosecurity measures at national borders is influenced by thebehaviour and levels of involvement of travellers. Involvement is the importance orrelevance of an object or situation to an individual. Involvement helps regulate theway in which people receive and process information and thus influences the extentof information searching for decision making, and information processing andpersuasion. In this study, we drew on the concept of involvement to investigate theresponse of individuals to New Zealand biosecurity requirements.
We used the process-oriented niche model CLIMEX to estimate the potential global distribution of serrated tussock under projected future climates. Serrated tussock is a drought-tolerant, wind- and human-dispersed grass of South American origin that has invaded pastures in Australia, Europe, New Zealand, and South Africa. The likely effect of climate change on its potential global distribution was assessed by applying six climate-change scenarios to a previously developed model.
We conducted two field experiments to explore the reactions of feral ferrets (Mustela furo) to traps and bait dispensers set on pastoral farmland in central North Island, New Zealand. First, in 2004 we showed that only six of 13 radio-collared ferrets resident near four observation stations approached to within 8m of two stations, and only three of the six entered over 8days of observation. Five of the 15 ferrets available on the 6000ha study area eluded recapture, although all remained present.
