Genetically Modified Foods Essay EU – Food, water and energy systems are becoming increasingly vulnerable: over the next 20 years the global demand for energy and water, is projected to rise by 40%. The need help writing a research paper food system, linked to population growth and lifestyle changes, is the most vulnerable of all and the global human demand is projected to grow by 70% until 2050 (FAO, 2009).

Valentines Day Writing Paper Even if agricultural production, is currently sufficient to meet buy viagra in the philippines food demand and at the global scale the growth rate of the population, one of the driving forces behind environmental problems, is less rapidly because of decreasing birth rates after 1965, the “total population size is nevertheless projected to increase from 7 billion people today to about 9 billion people by around 2050” (UN, 2009). The situation may worsen in coming years, because cultivated land area and arable land, absolutely essential to agriculture, decreasing by 1.5% per year, are decreased by 13% in the last 50 years. At the same time their productivity is increased by 259% and the effect of http://www.hypehoodie.com/speech-therapy-homework/ speech therapy homework extensive farming systems is devastating the land and is against the well-being of the citizens.

Global Land Assessment of Degradation published by the United Nations’ Food and Agricultural Organization (FAO), shows that the development of land degradation, defined as a long-term decline in ecosystem function http://www.catcoglobal.com/?perfect-essay-writers perfect essay writers , has 9 indicators interpreted on the basis of a Global Land Use Systems map

  • Land cover
  • Urban and protected areas
  • Livestock pressure
  • Irrigation Crops
  • Temperature and thermal regime
  • Rainfall regime
  • Dominant soil and terrain slope
  • Population density
  • Poverty

The symptoms include soil erosion, nutrient depeltion, salinity, water scarsity, pollution, disruption of biological cycles and loss of biodiversity. The hardest hit are South Africa, Indo-China, Myanmar, Malaysia and Indonesia, central Australia, the Pampas, swaths of the high-latitude forest belt in North America and Siberia, with different percentage of global degrading.

To produce food in sufficient quantities Europe, for example, relies on intensive agriculture which impacts the environment and our health but the current economy has led to a series of contradictions, including the production of a very expensive food, unsustainable farming practices, damage to biodiversity and water resources and large food waste in rich countries. Food provision is a key determinant of human health but associated with major impacts on land cover and also affects the quality of soils, water and air, but agriculture is an important economic sector and it is facing several challenges. 

You need to know that land degradation is defined as a long-term decline in ecosystem function and degradation is driven only by its management or catastrophic natural phenomena. A long-term food security can probably deliver on the goal by reducing the overall ecological impact of agriculture with precision farming techniques (reducing fertilisers, pesticides) and with organic practices. We need to improve resource efficiency to conserve the natural environment and the services it provides to us, and the transition to a viagra 150 mg from usa Green Economy is a key priority in the years ahead, ensuring food accessibility and protecting soil, water and biodiversity.

Despite the green revolution started in 1968, help with scientific notation homework world hunger has not been eradicated, almost a billion people live in hunger or malnutrition.

custom written term papers Ybele Hoogeveen, of the European Environmental Agency (EEA), said : “There is a strong link between our health and well-being and food. Agriculture also contributes to climate change and air and water pollution, all of which may affect human health and well-being indirectly. The way we produce our food affects the attractiveness of the landscape we live in. A switch to low-productive systems would be unrealistic and counterproductive. We can’t afford farming to be inefficient, economically nor environmentally. At the same time, we need to reduce the pollution from agriculture. This poses a dilemma. Organic farming, an added value for the farmer, (without pesticides and fertilisers) can also be intensive, but is estimated to yield roughly 20 % less than intensive agriculture. To continue producing the same amount of food, we would then need to allocate more land to agriculture”.
