A prescribed burn in a Pinus nigra stand in Portugal Controlled burning of a field outside of Statesboro, Georgia, United States in preparation for spring planting Controlled or prescribed burning, also known as hazard reduction burning (HRB), backfire, or swailing, is a technique sometimes used in forest management, farming, prairie restoration or greenhouse gas abatement.
In industrialized countries, controlled burning is usually overseen by fire control authorities for regulations and permits. History[edit] Controlled burns have a long history in wildland management. Fires, both naturally caused and prescribed, were once part of natural landscapes in many areas. Savanna Explorer - Northern Australia - North East Queensland - Fire - Trafalgar Station. By Roger Landsberg, Trafalgar Station From Savanna Burning — Understanding and Using Fire in Northern Australia , Tropical Savannas CRC, Darwin 2001 Trafalgar Station near Charters Towers is a 32,000 hectare property with a carrying capacity of about 3200 adult equivalents. Pasture management and fire I aim to "spell" 15–20% of the property each year to allow the grass to strengthen and drop seed; the build-up of pasture gives us an option to burn.
If the season is poor, I may keep the grass for drought feed or burn later. However, paddocks that have been locked up after clearing virgin scrub are always burnt and allowed a full growing season before being grazed. Fire management The pasture is usually burned in October–November when the weather is hot, slightly humid and the winds are fairly light, preferably from the north. The conditions must be right before I burn. After the fire, stock should be excluded until ground cover is well established, preferably after good rain. Cost of burning.
Vertical farming. Vertical farming is cultivating plant or animal life within a skyscraper greenhouse or on vertically inclined surfaces. The modern idea of vertical farming uses techniques similar to glass houses, where natural sunlight can be augmented with artificial lighting.[1] Types[edit] "Vertical farming" was coined by Gilbert Ellis Bailey in 1915 in his book Vertical Farming.
This was not the current meaning—he wrote about farming underground with the use of explosives.[2] Modern usage refers to skyscrapers using some degree of natural light. Mixed-use skyscrapers[edit] Mixed-use skyscrapers were proposed and built by architect Ken Yeang. Despommier's skyscrapers[edit] Ecologist Dickson Despommier argues that vertical farming is legitimate for environmental reasons.
Vertical farming according to Despommier thus discounts the value of natural landscape in exchange for the idea of "skyscraper as spaceship". Despommier's concept of "The Vertical Farm" emerged in 1999 at Columbia University. The Vertical Farm Project - Agriculture for the 21st Century and Beyond | www.verticalfarm.com. Food security. 'Extreme' food insecurity (2010)[1] Humans are using an increasing amount of Earth’s annual production of plants Food security is a condition related to the ongoing availability of food.
Concerns over food security have existed throughout history. There is evidence of granaries being in use over 10,000 years ago, with central authorities in Civilizations including Ancient China and Ancient Egypt being known to release food from storage in times of famine. The 1996 World Summit on Food Security noted that "food should not be used as an instrument for political and economic pressure".[3] According to the International Centre for Trade and Sustainable Development, failed agriculture market regulation and the lack of anti-dumping mechanisms engenders much of the world's food scarcity and malnutrition.
Measurement[edit] Food insecurity is measured in the United States by questions in the Census Bureau's Current Population Survey.

Sustainable agriculture is the act of farming using principles of ecology, the study of relationships between organisms and their environment. The phrase was reportedly coined by Australian agricultural scientist Gordon McClymont.[1] It has been defined as "an integrated system of plant and animal production practices having a site-specific application that will last over the long term" For Example: Satisfy human food and fiber needsEnhance environmental quality and the natural resource base upon which the agricultural economy dependsMake the most efficient use of non-renewable resources and on-farm resources and integrate, where appropriate, natural biological cycles and controlsSustain the economic viability of farm operationsEnhance the quality of life for farmers and society as a whole[2] Farming and natural resources[edit] The most important factors for an individual site are sun, air, soil, nutrients, and water.
Water[edit] Indicators for sustainable water resource development are: Australia must lead global move towards soil security - News and Events - University of Sydney. 11 February 2011 Top international soil scientists have called on Australian governments and industry to lead the world in collaborating with farmers to increase soil carbon for improved soil security. The call was made as part of the recent global soil carbon summit held at the University of Sydney, with the support of the United States Studies Centre's Dow Sustainability Program and the University's Faculty of Agriculture, Food and Natural Resources.
Adjunct Professor in Sustainability at the US Studies Centre and summit convenor, Robert Hill said soil issues needed to have priority alongside climate issues. "Australian agriculture is set to experience the destructive effects of ongoing climate change first and hardest. By improving the sequestration of carbon in soil to enhance soil security we can increase production and reduce carbon emissions at the same time. It is a win-win solution. " Land Manager.

This website was created by the NT InfoAccess program supported by Territory NRM, Charles Darwin University and the Northern Territory Government. It aims to meet the information needs of north Australian land managers including pastoralists, Landcare groups Indigenous groups and government agencies. It enables people to make better land management decisions by providing information on the soils, pasture and plants and animals that need to be looked after, and on the problems land managers face, such as wildfire, weeds and pest animals. Importantly, the site allows north Australian land managers to share information. The Future of Food - Landline - ABC. ANNE KRUGER, PRESENTER: After promising a national food plan during last year's election, this week the Federal Government gave a glimpse of what might be in it with the release of an issues paper. And there are a lot of issues to consider when trying to work out how to double food production by 2050 to meet global demands while protecting fragile resources.
International and local experts say Australia could be a leader in securing global food supplies by exporting its farming and agricultural science smarts, as well as its produce. But there are also warnings that the country is not immune from a global food crisis and the instability that comes with it. Kerry Staight filed this special report. PETER CARBERRY, CSIRO: In the next 40 years, we have to produce as much food as the world has produced in the last 500 years. JOHN CRAWFORD, UNI. OF SYDNEY: You can work out on the back of an envelope that we're not going to have enough food in 20 years' time, by far.
MICHAEL D'OCCHIO, UNI. International Fund for Agricultural Development. IFAD logo The International Fund for Agricultural Development (IFAD) (French: Fonds international de développement agricole; FIDA) (Italian: Fondo Internazionale per lo Sviluppo Agricola) is a specialized agency of the United Nations dedicated to eradicating rural poverty in developing countries. It was established as an international financial institution in 1977 as one of the major outcomes of the 1974 World Food Conference. Seventy-five per cent of the world's poor live in rural areas in developing countries, yet only 4% of official development assistance goes to agriculture. The strategic policy of IFAD is detailed in Strategic Framework for IFAD 2011–2015: Enabling the Rural Poor to Overcome Poverty.
The current President of the IFAD is Mr. Goal[edit] IFAD's goal is to empower poor rural women and men in developing countries to achieve higher incomes and improved food security. Objectives[edit] Working in partnership to eradicate rural poverty[edit] Membership[edit] IFAD member states. The coming famine: risks and solutions for global food security. Growing scarcities of water, land, oil and nutrients will combine with climate change to create a serious threat to global food security in coming decades. These could result in major regional famines, wares and refugee crises, Julian Cribb warns. Image: richardmasoner, Flickr CC-licensed. Please click on the images to enlarge. Most of us have by now heard the forecast there will be 9.2 billion people in the world of 2050.
But current projections suggest human numbers will not stop there – but will keep on climbing, to at least 11.4 billion, by the mid 2060s. Equally, the world economy will continue to grow – and China, India and other advancing economies will require more protein food. Thus, global demand for food will more than double over the coming half-century, as we add another 4.7 billion people. The central issue in the human destiny in the coming half century is not climate change or the global financial crisis. The world food production system today faces critical constraints.
