What the most recent books on city sustainable development, experience of world cities?
Sustainable development, city planning, experience of cities around the globe.
The Expert answers:
This is a very old literature. However, the “new classic” book is “The Spatial Economy” by Fujita, Krugman, and Venables. There is some mathematics in the book, but the basic principles can be understood, I think, if you ignore the math.

How does sustainable development endure high standard of living and increase in productivity?
Can someone also please explain how sustainable development makes sure that the objectives of removal of poverty, inequality and illiteracy are achieved?
The Expert answers:
I think sustainable development enduring high standard of living and increase productivity easily apply and feasible to rich resources country, like Canada. For instance, they can log the whole mountain of woods and replant it. Many years later, the whole mountain goes green again. Salmon hacting by manual spawning can increase its productivity is common in Canada. They grow wheats and mustard a lot there, too. People can buy cheaper draft beer and more hotdogs go with mustard. In contrary, Hong Kong is not a viable city to provide sustainable development for its six million plus citizens because it’s not a natural resources base city, and government personnel has taken too much money out of the system and spend lavishingly too much for themselves. I think a city or country must have good leaders to provide sustainable development endure high standard of living and increase productivity. Hong Kong is just a city become the people don’t give a damn to each other. The inflation goes up rapidly and the government just by selling the lands at extra high prices and investing the monies into the foreign currency exchanges and stock markets. Hong Kong is notoriously known as top five most expensive and polluted city in this world. Hong Kong has the highest poor and rich gap in this world with gini coefficient of 0.5333 and 0.3 is the norm. How to remove the poverty in Hong Kong, for instance, Hong Kong government should cut the overpaid civil servants salaries, lower the property values, keep the Heng Seng index down to less than 10000 point. Then Hong Kong will become a cheaper city to live. Educational subsidary has provided free education up to grade 9 now. In most countries, free education is up to grade 12 or completion of secondary school .

What needs to happen to move towards sustainable organic agriculture as a means to feed our growing population?
What do you think needs to happen to move towards sustainable organic agriculture as a means to feed our growing population?
The Expert answers:
A big rise in oil prices and a decentralization and decorporatization of agriculture.
Farming will have to go from feeding the world to feeding regions. We will need a lot of 500 acre diversified farms, instead of CFO and mono cropping over millions of acres.We will also need urban growing and people growing at least 15% of their own food.
It will likely take not just petroleum getting too expensive to use for farming but also massive famines over the world, rioting and millions dying before anything really changes.
