What do you mean by two cycles? as in health, human development, sustainability x2 ? Can you give an example 
Hi V,
I think this is what evawu means by 'two cycles'
Often these questions will be linked to either stimulus material or you'll have to use one of the programs you studied.
I'll use the immunisation program I studied to show you what Eva means by two cycles.
'Using examples, explain how an immunisation program could lead to sustainable human development'
(About a 6 mark question)
It's really important you plan this question before you start writing to make sure that you inter-relate SHD otherwise it can get really messy and confusing for examiners.
Example 1:
"A program such as Child Days Plus which is aimed to boost immunisation rates and reduce child morbidity and mortality provides vaccinations for measles and hepatitis B in order to reduce risk of contracting these diseases and improving
physical health [health]. Through being healthy, an individual is able to become trained by UNICEF (who administers the program) to deliver vaccinations to other members in the community, therefore
improving their capabilities and participation in the community [human development]. These medical skills gained can be used to pursue meaningful employment in the health sector which can increase the gross national income (per capita) of a region, therefore ensuring
economic sustainability [sustainability]"
Do you see how I used one example of implementation of the program to inter-relate? Now I'm going to use another one to finish my 6 mark answer.
Example 2:
Child Days Plus also provides maternal and neo-natal tetanus injections to reduce the risk of tetanus in children and
improve physical health. [health] If a child is healthy they are then able to attend school and gain
gain knowledge about the importance of vaccinations and achieve their full potential [HD]. With this newly acquired knowledge about the importance of vaccinations, children are able to pass it onto future generations, ensuring
social sustainability.
