Existing Structures of Global Governance

This chapter is about global governance and structures to deal with complex global environmental problems. Governance is a set of complex interactions between state and non-state actors at the global level.There are several key trends to look at in global environmental governance, including the increase in international environmental agreements and the involvement of more actors. These have led to fragmentation, segmentation, and decoupled decision making, as well as increasing inter-linkages…

Aggregate Demand with Flexible Exchange Rate

In this chapter, Professor Sachs discusses international trade and how it is affected by the exchange rate, which is in turn affected by financial flows and the differences of interest rates at home and abroad. There are two ways to manage the exchange rates of a country, namely by supply and demand, or by the central bank setting the price. This is explained using the case of exchange rate of Renminbi to the US dollar, as managed by the People’s Bank of China. Countries have the right…

Types of planning include spatial planning, strategic planning or growth management planning, spatial literacy planning, precinct-level planning, and other intersectional types of planning. This is considered through the case study of the City of Johannesburg, South Africa. Watch Part I This video is licensed…

Aggregate Demand with Fixed Exchange Rate

This chapter begins by explaining the impact of aggregate demand in an open economy, via fixed and flexible exchange rates. In a fixed or pegged exchange rate, the central bank doesn’t allow the value of the national currency to deviate relative to foreign currencies, and will intervene in foreign markets to stabilize price. Professor Sachs explains aggregate demand through fiscal expansion or government spending, and then talks about how currencies operate when they are pegged using the…

Aquaculture and Mariculture

Most of marine aquaculture is not sustainable and is actually taking away protein from the human population. Around 1990, the wild capture fisheries leveled off at 95 million metric tons per year while aquaculture had an almost exponential rise. Most of aquaculture is freshwater fish. Recirculating land-based systems need huge infrastructure and have a very high energy demand with a high carbon footprint. At the medium level, there are net pens for sea bass and salmon and at the low level,…
