Transcript of Sustainable agriculture

Foundation Methods References Animal Production This is not only limited to plants. Livestock operation has been around as long as its plant counterpart. In fact they are highly complementary both biologically and economically. what is sustainable agriculture? Different methods are used in a variety of different ways in order to achieve common goals such as weed control, pest control, disease control, erosion control and high soil quality. Some techniques used by farmers are:

Crop Rotation: Method of growing different crops in succession in the same field. Prevents multiplication of pests and offers a variety of nutrients and minerals preserved in soil.

Cover Crops: Method of covering crops preventing soil erosion, suppressing weeds and enhancing soil quality. Also reduces need for chemical inputs.

Soil Enrichment: Method of enhancing quality of soil by leaving crop residues in the field after harvest, plowing under cover crops, or adding composted plant material or animal manure. Good crops means less fertilizer and less pests.

Natural Pest Predators: Method of creating a balanced environment encouraging natural predators of pests to feed off near crops.

Biointensive Integrated Pest Management: Method of using a combined tactic of biological and chemical measures to ensure greatest pest removal. Sustainable Agriculture Why perform sustainable agriculture? Why is sustainable agriculture important? Sustainable agriculture is the act of farming using principles of ecology, the study of relationships between organisms and their environment. - Satisfy human food and fiber needs
- Enhance environmental quality and the natural resource base upon which the agricultural economy depends
- Make the most efficient use of non-renewable resources and on
-farm resources and integrate, where appropriate, natural biological cycles and controls
- Sustain the economic viability of farm operations
- Enhance the quality of life for farmers and society as a whole As the time pass they gradually become separate and have created their own specialization.
Despite that, many of the principles outlined in crop production apply to both groups such as: Management Planning: The manager sets a plan that monitors progress towards goals. The plan includes calendars of operations, stock flows, forage flows, labor needs, herd production records and land use.

Animal Selection: The manager must select animals to produce in terms of forage sources, landscape, climate and using his own skill.

Animal Nutrition: The manager takes this into consideration because it is one of the largest single variable cost in any livestock operation. The feed come from other sites in the ranch or imported off the farm.

Reproduction: In combination with good genetic stock, the manager adapts the reproduction season to fit the climate and sources of feed and forage reduce health problems and feed costs. The importance of sustainable agriculture is to maintain the growing demand of food without destroying land in the process. http://m.ucsusa.org/food_and_agriculture/solutions/advance-sustainable-agriculture/sustainable-agriculture.html http://www.theinnovationdiaries.com/1152/sustainable-agriculture/ http://www4.agr.gc.ca/AAFC-AAC/display-afficher.do?id=1175526032952&lang=eng http://www4.agr.gc.ca/AAFC-AAC/display-afficher.do?id=1294433605951&lang=eng http://www.syngenta.com/country/ca/en/corporate-responsibility/Pages/SustainableAgriculture.aspx http://www.gracelinks.org/246/sustainable-agriculture-the-basics Future Impact Animal Production By 2050 there is estimated to be another 3 billion people living on earth and food demand would have greatly increased. Sustainable agriculture helps maintain the environment and meets product demand. It provides high yields without undermining the natural systems and resources. Farmers who work sustainably work efficiently with natural processes rather than ignoring or struggling against them. Sustainable agriculture efficiently enables for permaculture and allows for the preservation of the environment due to the lack of chemical use. http://www.sarep.ucdavis.edu/about/def#animal-production-practices

People think of sustainability as being correlated with “organic,” but organic may more realistically be the most extreme version of “sustainable agriculture.”
The definition of sustainable is to be able to maintain the capacity to continue producing the quantities and qualities of products as in the past.

Organic agriculture has had a major impact on environmental attitudes across agriculture. Overall the organic production uses fewer chemicals; as well farmers perform sustainable farming techniques to sustain crop lands.
A way to make this more viable and cost effective overall is if government incentives are placed for farmers to produce more organic crops, as well reduce the use of chemical substances, instead hire labor, this will boost the local economy. Finally if more people purchase organic products there will be an increase in demand and revenue for the farmer, which in time will decrease costs to purchase set organic products which benefits the consumer. Overall Sustainable agriculture is a viable, cost effective ways to carry on are agriculture needs in a responsible manner with the environment in mind. Sustainable Agriculture is cost effective and viable
