Section 8 Livelihood and Economy - Primary Activities Classification of Economic Activity Subsistence Agriculture Commercial Agriculture Other Primary Activities Trade in essential exercises Tea Plantation, Sri Lanka Copyright 2003 by Jon C Malinowski

Slide 2

Classification of Economic Activities & Economics Factors - Physical environment and social contemplations Exploit assets subordinate upon innovation Political choices Economic components of interest Categories of Activity Quinary Activities Executive Decision Maker Quaternary Activities Info/Research/Management Tertiary Activities Retail & Wholesale/Personal & Prof. administrations Transportation & Comm. Auxiliary Activities Manufacturing/Processing/Construction/Power Production Primary Activities Agriculture/Gathering/Extractive Industries

Slide 3

Types of Economic frameworks Subsistence Economy merchandise/administrations for the utilization of makers/family Very few individuals are individuals from one and only kind of monetary framework Commercial Economy makers showcase products/administrations, supply-request/rivalry Planned Economy government controlled/chose costs Systems subject to change - advertise/globalization Transportation is a key variable Isolation confine the entrance to outside world (F ig 8.4 )

Slide 4

Primary Activities: Agriculture Def. : developing products and tending animals, available to be purchased or subsistence. ( Fig 8.5 - developing season) 10% of the aggregate earth land is for yield cultivating. Declining pattern in farming work in creating nations ( Fig 8.6 – Agricultural Employments ) Developed - 8% in a large portion of W. Europe, < 3% in the US. Agribusiness is still the significant parts in creating nations ( Fig 8.7 – Agriculture and GDP )

Slide 6

Subsistence Agriculture Involves almost add up to independence with respect to its individuals. No trade (or negligible, assuming any). sustenance for themselves as it were. Two sorts Extensive : expansive zones of land and insignificant work input per unit range. Creation and pop thickness is low. Serious : development of little landholdings through the consumption of awesome measures of work per unit zone. Creation and pop thickness are both high. ( Figure 8.8 Subsistence Agriculture Areas )

Slide 7

Extensive Subsistence Agriculture Nomadic crowding ( Figure 8.8 – Subsistence agribusiness ) - meandering and controlled development of animals reliant on characteristic rummage - the most broad kind of land utilize framework. Sheep, goat, and camels are most regular and others, for example, steers, steeds and yaks are imperative as well. Creature gives drain, cheddar, meat for sustenance; hair, fleece and skins for garments; skin for haven and feces for fuel. Itinerant crowding is declining. Social/financial/culture changes are bringing about migrant gatherings to adjust their lifestyles or vanish altogether. Moving development - turning field once soil lose richness. Swidden and slice and-blaze . (8.9) Slash-and-Burn (or Shifting Cultivation) No information of soil science, treating, or water system, once the dirt get to be barren, they move to another bundle of land, clear the vegetation, turn the dirt and attempt once more. 150 to 200 million individuals in Africa, Middle America, tropical South America and parts of Southeast Asia.

Slide 8

Shifting development/Slash-smolder Slash-and-blaze : procedure of get ready low ripeness soils for planting. Smoldering add minerals to the dirts, in low level of populace Shifting - pivoting the fields to keep soil ripe After blazing, plant harvests, for example, maize (corn) millet (oat grain), rice, manioc, yam, and sugarcane

Slide 9

Intertillage: routine of blending distinctive seeds and seedlings in the same swidden To lessen the danger of catastrophes from yield disappointment, to build the healthful adjust of the neighborhood eating regimen, to forestall loss of soil dampness, control of soil disintegration R:Rice G:Groundnut M:Maize Y:Yam WY:White yam AP:Air potato V:Bamara groundnut Cu:Melon Pp:Pumpkin L:Gourds

Slide 10

Swidden Agriculture (279) Low pop. thickness much land is expected to bolster few individuals Shifting Cultivation is established on the islands of Kalimantan (Borneo), New Guinea, and Sumatra in Indonesia. Presently just in uplands of SE Asia in Vietnam, Thailand, Myanmar and Philippines, Nearly the entire of Central and West Africa far from the coasts, Amazon bowl , and extensive segments of Central America Boserup theory - pop increments require expanded contributions of work and innovation to make up for decreases in the common yields of swidden cultivating. The pop increment constrains an expanded utilized of tech as a part of cultivating, changing over from broad to concentrated subsistence agribusiness.

Slide 11

Intensive Subsistence Systems Half of the general population of the world occupied with this action Exchange of ranch items Requires huge contributions of work, little plots and high dependence on composts Plant grain, vegetables, and raise creatures… Mostly in rainstorm Asia. warm and damp waterway valleys and delta Planting rice shoots by submit standing new water is a dull workmanship (8.10) Cooler/drier Asia - wheat and millet is planted. Rice gives 25 - 80% calories to more than 2.8 billion pop. Water administration is essential to the rice generation Rice Landscape - levees, supplies, trenches, waste channels, and patios to stretch out level land to valley inclines Swine, ducks and chickens are principle meat. Cows utilized for work and create composts.

Slide 12

Urban Subsistence Farming Provide 1/7 of the world nourishment creation - for the most part in Asia occupied with little garden plots, patio animals reproducing and bringing fish up in lakes and streams. China, Taiwan, Cuba, Kenya and numerous different nations inhabitants occupied with urban subsistence cultivating. In parts of the creating scene, this has lessened the frequency of grown-up and tyke unhealthiness in urban areas. Numerous depend on this as sole salary Advantages-change over waste from issue to asset by diminishing keep running off and disintegration from open dumps and by maintaining a strategic distance from expenses of wastewater treatment and strong waste transfer. Cases - Sudan, Calcutta.. Disservice - infections, water contamination

Slide 13

Origin of Green Revolution Started in 1960s, Philippino look into crossed a Chinese rice with Indonesian assortment and delivered IR8 rice with greater head of grain and more grounded stem. In 1982, they delivered IR36, the most broadly developed yield on Earth IR36-blended from 13 guardians hereditary resistance against 15 vermin and developing cycle of 110 days which makes three products for every year conceivable. Diagramming of genome (12 chromosomes) is continuous, it will in the long run increment the generation and build up the imperviousness to maladies and vermin Green Revolution - 8.11 patterns in nourishment creation 1961-1999. Sparing an expected one billion individuals from starvation. Expanded calories per individual, pop with sufficient nourishment in creating nations hopped from 55% to 80%.

Slide 14

Green Revolution Disadvantages - water system demolished huge tracts of land, groundwater consumption, water wars, loss of customary/subsistence cultivating, sustenance creation going for fare, country society pulverized, decreased assortment of harvests, provincial pop moved to urban Not all regions profited from Green Revolution - reasons (late research exertion, incredible scope of developing conditions) Fig 8.12 - hereditary differing qualities of yield assortments , less than 100 species give the greater part of the world's nourishment supply. Asia - increases tumbled off - minimal prime land, less water, unfriendly ecol. furthermore, social outcomes. Indeed, even biotech can't help (shoppers' resistance..) Loss of local sustenance accessibility

Slide 15

Commercial Agriculture Production Control short supply ought to summon an expanded market cost (after tropical storm in Asia, vegetable cost going up) government control costs either too high or too low. (cultivate economy twisted while low nourishment cost is authorized, material bending while quit bringing in and sponsoring) Today's legally binding course of action in the U.S. up to 1/3 from 10% inside 50 years. More established supply/request advertise value instrument is not absolutely substantial yield or domesticated animals blend chose by business agriculturists mirrors an appraisal of market requests and costs includes concentrated land use close markets and broad land use at more far off areas.

Slide 16

von Thunen's model (8.14) force of land utilize, higher estimated/more perishable products are created in land nearer to the city. High transporting and popularity wares found in internal rings. "A part of every yield is eaten by the wheels" - saw by von Thunen, separate amongst market and generation site is the most vital assurance of the area Transport slopes (8.15) - crops with most noteworthy transport cost and market qualities will be become closest to the market. Transportation cost influence the state of Rings (8.16) Industrial and post-modern economy, arrive utilize is controlled by elements with urban extension. von Thunen model is less unsurprising

Slide 17

Intensive Commercial Agriculture Characterized by significant returns per unit of developed land Large measure of info - defended by natural products, vegetable and dairy items. Truck Farm creates extensive variety of vegetable and organic products with refrigerated trucks and custom bundling. (dissemination of truck homestead 8.17) Livestock-grain cultivating - developing grain for animals bolster. corn and animals at same homestead diminishing transportation cost. Animals cost higher than sustain, agriculturist change over their corn into meat on the ranch by nourishing it to the domesticated animals. In W. Europe, ¾ cropland is for domesticated animals grain cultivate. In any case, the estimation of its items per unit is not as much as that of the truck cultivate. They are more distant from the principle markets than are plant and dairy ranches.
