Population Change Possibilities
-Add through Birth
-subtract for death
-add from in migration
-subtract from outmigration
3 ways to limit population growth
1. Inc death
2. dec birth
3. Both
Where does most population growth occur?
-less developed countries
-mostly rural areas
Parmly Reading- Why Farmland Disappeared
-NJ agriculture
-affected by developers, competitors, and costs
-increase market and more ethnical food
-if we look for diversity, it could lessen competitions amongst farmers
-rising cost of input
-CHALLENGE: keep young farmers on the farm
Madden- Agriculture be Profitable
Can sustainable AG be profitable?
-claims it must be profitable or farmers wouldn't do it, so he wants farmers to change
-Rodale family-have multiple generations for promoting organic AG
-in the 50's people didn't discuss organic/vegetarian meals
-suggests sustainable or to be more efficient
- REGENERATIVE AG
-farmers must be provided management of physical and biological aspects of farm operation; know
financial management also!
Sustainable agriculture
production of food, fiber, or other plant or animal products using farming techniques that protect the
environment, public health, human communities, and animal welfare. This form of agriculture
enables us to produce healthful food without compromising future generations' ability to do the
same.
Regenerative Agriculture
Farm methods where abundance of safe nutritious food and fiber is produced using farming methods
that are ecologically harmless, sustainable, and profitable
-organic farming

-less chemicals
-better soil quality by using on-farm sources
-On-farm capitals to support its own operation
Johnson (Amish)
-organic and sustainable in the 1st place
-groups of Amish farmers in 3 different regions
-comparing how they practice AG
-maintaining productivity by being more efficient
-agricultural productivity: total output
-agricultural efficiency: output per unit input
ABOUT THE AMISH
-sustainable AG is part of their religion and they are against modern things
-they maintain high yields and save NRG ex: tractors vs horse plowing, liquefied petroleum gas vs
modern power
-limited demands are made on available resources
-Their way lasts 20-30 yrs. (horse/buggies/harness)
-use labor, simple tech, prevent poverty, and bankruptcy
Cummings (floating Rice)
-What is the role of biotech in inc. the food supply?
-it did inc. the food => for long haul when food was growing faster than pop. Growth --> more ppl
were adequately fed
-Indonesian
People of Indonesia
Cummings (floating rice article)
-culture mostly based on phases of moon
-rice fields: introduced high yield rice and pesticides
-rice went up but use of pesticides made an unnoticed pest become a huge problem
-it changed environment/culture/ everything and forced farmers to plant high yield rice
Was floating rice a good idea?
(Cummings)
- No, because it req. a high input as a result, only wealthy ones could maintain it.
-smallholders have small inputs so small yields, their yield not much higher than traditional growers,
but with more risk, headache and effort
-must be provision of joint services including skills, machines etc.
-marginal growers should be assisted. Rich ones control many things like land, labor, and legislators.
Mack (catalog of woes) -flowers-
-popularity of gardens in US 100+ years ago
-wanted more exotic things so they would import new flowers
