  • Food availability, access, stability and utilization are all part of the multi-dimensional nature of food security. The “availability” aspect, discussed here, refers to the availability of sufficient quantities of food of appropriate quality, supplied through domestic production or inputs. Productivity is usually considered the ultimate benchmark when comparing the performance of agricultural systems. For example, those involved in agricultural research and development want to know how much yield would be reduced if conventional agriculture were converted to organic agriculture.

  • During the past two centuries, scientists, farmers, and agricultural educators have tended to alternate their views of soil organic matter (SOM) between the extremes of great appreciation and low esteem. As an early 20th century bulletin explained, organic matter was “once extolled as the essential soil ingredient, the bright particular star in the firmament of the plant grower…” before it “…fell like Lucifer…” as a result of the findings of 19th century agricultural chemists that most of the plant structure (C, that is) originated in the atmosphere (Hills et al., 1908)....

  • Organic farming is a modern way of agriculture management, not using any chemical treatments which have negative effects on the environment, human health or animal health. It produces organic foodstuffs, and at the same time enhances the living conditions of animals. It contributes to environmental protection and helps biodiversity to increase. Organic farming does not mean going ‘back’ to traditional (old) methods of farming. Many of the farming methods used in the past are still useful today.

  • Despite the tremendous progress that has been achieved in water pollution, almost 40% of the U.S. waters that have been assessed by states do not meet water quality goals. About 20,000 water bodies are impacted by siltation, nutrients, bacteria, oxygen depletion substances, metals, habitat alterations, pesticides, and toxic organic chemicals. With pollution from point sources being dramatically reduced, nonpoint source pollution is the major cause of most water that does not meet water quality goals.

  • The essential oil industry is under threat from numerous issues at present. Rising agricultural input costs, particularly petrochemical based fertilizers and fuels are squeezing farmers’ profit margins. Rising food prices and the increasing value of housing and industrial land prices is creating competition for land, particularly around populated areas. Adverse weather conditions and changing climate are creating both short and long term problems. Poor crop yields are occurring much more regularly than before because of unusually heavy rain, hail, floods, heat-waves and cold snaps....

  • It will be recollected that, in addition to its mineral portions, the soil contains organic matter in varied quantities. It may be fertile with but one and a half per cent. of organic matter, and some peaty soils contain more than fifty per cent. or more than one half of the whole. The precise amount necessary cannot be fixed at any particular sum; perhaps five parts in a hundred would be as good a quantity as could be recommended. The soil obtains its organic matter in two ways. First, by the decay of roots and dead plants, also of...

  • The same amount of water has been present on our planet for about 4 billion years, since shortly after the Earth was formed. Since then it has cycled through evaporation, condensation, precipitation and surface runoff multiple times. Water scarcity as an abiotic factor ranging from moderate to severe stress levels, accompanied by loss of moisture in the soil, is extremely hard for most organisms to cope with, particularly terrestrial plants and their food-chain dependents.

  • Agriculture is also a significant source of economic growth. In developing countries, agriculture generates on average 29 percent of the gross domestic product (GDP) and employs 65 percent of the labour force. About two thirds of the world’s agricultural value added is produced in developing countries. At the same time, agriculture also plays an important role in transforming and urbanized economies, where industries and services linked to agriculture account for more than 30 percent of GDP (ibid.).

  • The market for organic food has increased considerably over the last decade due to consumer’s increasing awareness of both health and environmental issues (Soler et al., 2008). This growth in demand is expected to continue in the coming years, even though the situation differs from one country to another in term of type and quantities of production (Vindigni et al., 2002). The future of organic will, to a large extent, depend on consumer demand.
