  • These were his calculations: “Say a two year old grassfed steer dresses 300kg and Lean Meat Yield is 60 percent. Therefore 180kg of beef is produced. Say the animal drinks 40 litres /day (generous) for 730 days. That equals 29,200 litres divided by 180kg = 162 litres per kilogram.
  • However, while that statement was referenced in the report, the specific reference was missing from the list of references at the end of the report.
  • In the article Professor Hoekstra actually wrote that producing one kilogram of boneless beef required about 155 litres of water, taking into account only the water used for drinking and servicing that animal. However, when you added in 1300kg of grain, 7200kg of roughages (pasture, dry hay, silage and other roughages), and the water required to grow those feed sources, he said the water footprint of 1 kg of beef would add up to 15,500 litres of water.

  • Professor Hoekstra, from the University of Twente in the Netherlands, is the inventor of the Water Footprint concept, a method used to account for the total amount of water used to produce something.
  • Dr Perry said calculation procedures adopted in most estimates of water footprints are flawed, and that water footprints are incorrectly assessed on an absolute rather than a relative bas
  • A key concern was that ‘Water Footprints’ made no allowance for whether a producing area is water- plentiful or water-short.
  • “One must consider the scarcity or abundance of water and land, as well as downstream water uses to evaluate the significance of any environmental impact when compared to the status of these variables in the absence of grain or meat production. Simply comparing the water footprints of grain and meat does not provide helpful environmental information.
  • “It is overly simplistic and misleading to suggest that water footprints should be reduced without considering the context and purpose of water use.” “…Generalised water footprints are neither accurate nor helpful indicators for gaining a better understanding of water resource management.”
  • Previous media articles have reported claims that it takes between 50,000 and 100,000 litres to produce a kilogram of red meat. But these reported measures count every single drop of water that falls on an area of land grazed by cattle over the space of a year. And they do not take into account the fact that most of the water ends up in waterways, is used by trees and plants and in pastures, not grazed by cattle. “These calculations therefore attribute all rain that falls on a property to beef production, whereby the water is clearly being used for other purposes, such as supporting ecosystems” MLA explains in its Target 100 page.

    "The water-food-energy nexus is central to sustainable development. Demand for all three is increasing, driven by a rising global population, rapid urbanization, changing diets and economic growth. Agriculture is the largest consumer of the world's freshwater resources, and more than one-quarter of the energy used globally is expended on food production and supply. The inextricable linkages between these critical domains require a suitably integrated approach to ensuring water and food security, and sustainable agriculture and energy production worldwide."

hurricanes hazards

shared by Benjamin McKeown on 17 Sep 14 - No Cached
  • In the western Pacific they are called typhoons, and in the southern hemisphere they are called cyclones.  But, no matter where they occur they represent the same process.
  • Tropical cyclones are dangerous because of their high winds, the storm surge produced as they approach a coast, and the severe thunderstorms associated with them. Although death due to hurricanes has decreased in recent years due to better methods of forecasting and establishment of early warning systems, the economic damage from hurricanes has increased as more and more development takes place along coastlines.
  • Warm ocean waters (of at least 26.5°C [80°F]) throughout about the upper 50 m of the tropical ocean must be present.  The heat in these warm waters is necessary to fuel the tropical cyclone. The atmosphere must cool fast enough with height, such that it is potentially unstable to moist convection. It is the thunderstorm activity which allows the heat stored in the ocean waters to be liberated and used for tropical cyclone development. The mid-troposphere (5 km [3 mi] altitude), must contain enough moisture to sustain the thunderstorms. Dry mid levels are not conducive to the continuing development of widespread thunderstorm activity. The disturbance must occur at a minimum distance of at least 500 km [300 mi] from the equator. For tropical cyclonic storms to occur, there is a requirement that the Coriolis force must be present.  Remember that the Coriolis effect is zero near the equator and increases to the north and south of the equator.  Without the Coriolis force, the low pressure of the disturbance cannot be maintained.
  • ...6 more annotations...
  • There must be a pre-existing near-surface disturbance that shows convergence of moist air and is beginning to rotate. Tropical cyclones cannot be generated spontaneously. They require a weakly organized system that begins to spin and has low level inflow of moist air. There must be low values (less than about 10 m/s [20 mph]) of vertical wind shear between the surface and the upper troposphere. Vertical wind shear is the rate of change of wind velocity with altitude.  Large values of vertical wind shear disrupt the incipient tropical cyclone by removing the rising moist air too quickly, preventing the development of the tropical cyclone. Or, if a tropical cyclone has already formed, large vertical shear can weaken or destroy it by interfering with the organization around the cyclone center.
  • unstable atmosphere
  • his instability increases the likelihood of convection, which leads to strong updrafts that lift the air and moisture upwards, creating an environment favorable for the development of high, towering clouds.
  • Surface convergence (indicated by the small horizontal arrows in the diagram below) causes rising motion around a surface cyclone (labeled as "L"). The air cools as it rises (vertical arrows) and condensation occurs.  The condensation of water vapor to liquid water releases the latent heat of condensation into the atmosphere. This heating causes the air to expand, forcing the air to diverge at the upper levels (horizontal arrows at cloud tops).
  • Since pressure is a measure of the weight of the air above an area, removal of air at the upper levels subsequently reduces pressure at the surface. A further reduction in surface pressure leads to increasing convergence (due to an higher pressure gradient), which further intensifies the rising motion, latent heat release, and so on. As long as favorable conditions exist, this process continues to build upon itself
  • When cyclonic circulation begins around the central low pressure area, and wind speeds reach 62 km/hr (39 mi/hr) the disturbance is considered a tropical storm and is given a name.  When wind speeds reach 119 km/hr (74 mi/hr) it becomes a hurricane.

  • In 1900, 11 years after the founding of the Brazilian Republic, the Kayapo population was about 4,000. As miners, loggers, rubber tappers, and ranchers poured into the Brazilian frontier, missionary organizations and government agencies launched efforts to “pacify” aboriginal tribes, wooing them with trade goods such as cloth, metal pots, machetes, and axes.

  • Humans began to mine the ocean floor for diamonds, gold, silver, metal ores like manganese nodules and gravel mines in the 1950's when the company Tidal Diamonds was established by Sam Collins.
  • Diamonds are found in greater number and quality in the ocean than on land, but are much harder to mine. When diamonds are mined, the ocean floor is dredged to bring it up to the boat and sift through the sediment for valuable gems. The process is difficult as sediment is not easy to bring up to the surface, but will probably become a huge industry once technology evolves to solve the logistical problem.
  • Metal compounds, gravels, sands and gas hydrates are also mined in the ocean. Mining of manganese nodules containing nickel, copper and cobalt began in the 1960's and soon after it was discovered that Papua New Guinea was one of the few places where nodules were located in shallow waters rather than deep waters. Although manganese nodules could be found in shallow waters in significant quantities, the expense of bringing the ore up to the surface proved to be expensive. Sands and gravels are often mined for in the United States and are used to protect beaches and reduce the effects of erosion.
