Rwanda - Three Child Policy?

Currently Rwanda is planning to limit family size to three children. Rwanda currently has a birth rate of 6 and is estimated to double its poulation to 18million by the year 2030. The goverment wants to control the population as industry is not developing in line with population growth and soil is becoming overused for farming in order to try to supply enough food to the population. Many religious leaders are opposed to this suggestion. This is the first African country to try to set a limit on family size. Questions to think about - Do you think this is a good idea? Do you think Rwanda should try to limit births? How should they do it? What lessons can they learn from China?
