Q

The following are part of which section in elements determining Agroecosystem

  • Pastrolists
  • Agropastoralists
  • Transhumance
  • Ranchers
  • Mixed Substence farmers
  • Intensive industrial livestock producers
  • Aquaculturalists
  • Alternative farmers
  • Wildlife ranches
A

Human element (People)

24
Q

How does economics play a role in Agroeconomics

A
  • Subsistence (only have enough for the family now and that is it)
  • Production and above subsistences (Have enough for now and later)
  • Trade (so much you have enough to sell and trade)
25
The following define? - Mobile livestock-keeping to available pasture and water - Arid and semi-ariad envionment - includes camel, sheep, goats, and horses - Shapes diet (milk/meat) as well as culture
Pastoralism
26
What are the challenges to Pastoralism
- cross social and political barriers - Transmission of disease - Conflict for resources with agropastoralists, ranching and wildlife
27
What is defined as: - Some crop agriculture is carried out, usually at a home site, in addition to the extensive grazing of livestock - Semi-arid envionments - Camels, cattle, sheep, goats, equids = milk, meat, fertilizer, and culture - Due to fixed land use - poultry can be added
Agro-pastoralism
28
What is defined as: - A form of pastoralism in which herders and their animals move seasonally between two specific regions - Envionment where there are severe seasonal fluctuations, like the mountain agriculture of Scandinavia, Australia, Germany, Switerland and western US - Cattle, sheep, goats = milk, meat, fertilizer, culture
Transhumance
29
What is defined as - common in semi-arid to sub-humid zones that favor grasslands (EX: western US) - Requires large amounts of privately owned or govenment leased land - Mainly meat production (ruminants)
Ranching
30
What type of agriculture activity is the most important farming activity in the Amzon region today
Cattle ranching
31
What percent of deforstation in Brazil is due to cattle ranching
70% - large areas of forest are cleared and replaced by grass, turning the ecosystem on its head - tropical pastures have a short life cycle and are easily attacked by insects pests and diseases. they are abandoned and more forest cleared
32
What is defined as: - Sedentary systems in which crops are the main source of food, with animals supporting the farming operation (traction, fertilizer, transport, saving, food, and risk of diversification) - sub humid to humid evn. - The most widespread form of agricultural activity in the world - Ruminats, poultry, swine, equids, and small animals
Mixed subsistence farming
33
What is the most widespread form of agricultural activity in the world
Mixed subsistence Farming
34
Define the impacts of small farm sizes
- **Currently in east africa, average farm size is less than 1 ha (2.5 acres) due to ongoing subdivision** - **Unable to support large stock** - **Greater emphysis on small stock** - limited access to external inputs - productivity and profitability of land is reduced
35
What is the average farm size in the USA
444 acreas
36
What is defined as: - sedentary crop and livestock agriculture where the main reason for crop reduction is to feed livestock - dairy, eggs, poultry, speacility fibers, and meat - usually occurs when there is a market demand for livestock products and suitaable access to infrastructure for more intensive animal husbdnary - increasing in peri-urban settings
mixed speacility farming
37
What is defined as: - concentrated animal feeding opertions (CADO's)
intensive industrial livestock production
38
Production is independent of the enviornment but heavily impacts the enviornment which requires large amounts of?
non-renewable resources
39
List some common examples of diseases related to production and high-density confinment
- LDA - rumen acidosis - liver abcess - enterotoxemia
40
What type of operation is the most rapidly growing system of farm animal production
Concentrated animal feeding operations
41
____% of growth in live stock sectors now come from CAFOs
80%
42
What are the major advantages of intensive agriculture
cheaper food - more predictable over time greater variety and availability - many hybrids are disease resistant longer shelf life - storage technology is increadible fewer geopgraphic limitations - fertilizers and irrigation hae made more lands available - may be able to change/Alter the enviornment Less dependance on human labor - lower man: machine ratio Decreased time to market - faster transportation in higher quality and shelf life
43
What are common disadvantages of intensive agriculture
Concentrated by-products - runoff, manure, odor, other wastes animal welfare issues - highly variable environmental impact - soil, surface water and water systems
44
What are the benefits of food production and publich health
- intensive food (around 10% of disposable income) - safer than ever before - positive balance of trade (even internationally) - agriculture is the main power across the world
45
What are the drawbacks of food production and public health
- resultant change to pathogens - enviornmental concers - antimicrobial resistance (historically 80% of all antibiotics produced were used in livestock and poultry)
46
its obvious that intensive agricultural production techniques have certain negative outcomes on human and animal health, however (finish the phrase)
one should be careful in critizing system that successfully feeds a significant portion of the worlds population (especially if ones mouth is full)
47
As more milk of produced, is more or less methane and waste produced
LESS
48
the following are defined as: - the cultivation of aquatic plants and animals - fresh water fish - brackish water - marine water - can be intensive production or part of mixed agricultural systems
Aquaculture
49
Organic farming is an example of?
alternative agriculture
50
What is the difference in organic livestock production compared to normal farming
- avoids the use of synthestic compounds (growth regulators / feed additives) - encourages the use of natural compounds or practices (minerals, biological pest contron, integrated pest management) to control disease - limited capactiy and limited market
51
What is defined as: - the rearing of wild animal species in confinment in a semi-doomesticated state for commercial exploitation - food production, skins and leather, sale of live animals - ungulates, fowls, rodents, reptiles and bison
Game ranching
52
what is defined as: - puppy raising - horse racing - greyhound racing - pet birds - fish - reptiles
companion and hobby animals
