Commercial and subsistence farming

A

Activity 1

To compare sketches illustrating two farms with regard to given criteria [lo 1.6]

Sketch A Sketch B
Buildings
Implements
Farming methods
Cultivated products

In sketch A the people living on the land farm to meet their own needs only. They usually do not need a large piece of land. They only produce enough food for their own use. They sometimes have food left to exchange or sell to supply in the need of other people. A variety of crops is planted, and they also provide their own meat, eggs and milk. The farmer and his family do all the work themselves as they do not make a profit from farming and can therefore not pay wages. This kind of farmer is known as a subsistence farmer .

The farmer in sketch B farms with one main crop, namely maize. He produces large quantities that he sells at a profit. He is able to live on the money for a long time and can also buy seed for the next harvest. He does not produce his crop for his own use and therefore buys the food he wants to eat. These farmers are known as commercial farmers and their motive for farming is the profit they can make.

Activity 2

To plan your own subsistence farming [lo 1.7]

Make a list of the basic foods that you need for survival.

You are now a subsistence farmer. Suppose that you have been given a piece of land of approximately 5 000 square metres (70 x 70 metres or half a hectare) in the southern Cape where the soil is very fertile. There is a farmhouse with all necessary services, a dam, a permanent river and fencing on the land. Remember what the basic foodstuffs that you need for survival are and start planning your farming activities. Draw a plan (map) with a key to show what your farm will look like from the air.

Assessment

Learning outcome 1: geographical enquiry

The learner will be able to use enquiry skills to investigate geographical and

environmental concepts and processes.

Assessment standard

We know this when the learner:

1.6 uses information from sources (including own observations) to answer questions about people and places (e.g. “Why is it like that?”) [answers the question];

1.7 uses geographical and environmental concepts and terms to report on enquiries in different ways (e.g. writing a paragraph, using a poster, artwork).

AMJAD
preparation of nanomaterial
Victor Reply
Yes, Nanotechnology has a very fast field of applications and their is always something new to do with it...

good afternoon madam
AMJAD
what is system testing
AMJAD
what is the application of nanotechnology?
Stotaw
In this morden time nanotechnology used in many field . 1-Electronics-manufacturad IC ,RAM,MRAM,solar panel etc 2-Helth and Medical-Nanomedicine,Drug Dilivery for cancer treatment etc 3- Atomobile -MEMS, Coating on car etc. and may other field for details you can check at Google
Azam
anybody can imagine what will be happen after 100 years from now in nano tech world
Prasenjit
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
Azam
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
Prasenjit
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
Damian
silver nanoparticles could handle the job?
Damian
not now but maybe in future only AgNP maybe any other nanomaterials
Azam
Hello
Uday
I'm interested in Nanotube
Uday
this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
Prasenjit
can nanotechnology change the direction of the face of the world
Prasenjit Reply
At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.

the Beer law works very well for dilute solutions but fails for very high concentrations. why?
