1. Ecological Macroeconomics: Consumption, Investment, and Climate Change

Abstract:
The challenge of reducing global carbon emissions by 50-85 per cent by the year 2050, which is suggested by the Intergovernmental Panel on Climate Change (2007a) as a target compatible with limiting the risk of a more-than-2ºC temperature increase, clearly conflicts with existing patterns of economic growth, which are heavily dependent on increased use of fossil fuel energy. While it is theoretically possible to conceive of economic growth being “delinked” from fossil fuel consumption, any such delinking would represent a drastic change from economic patterns of the last 150 years.

2. Reconciling Growth and the Environment

Working Paper

Abstract:
Macroeconomic theory and policy are strongly based on the assumption that economic growth is a fundamental goal. The environmental realities of the twenty- first century compel a reassessment of macro theory in terms of the impact of current growth patterns on planetary ecosystems.

Abstract:
The trend in mainstream economic thought about macroeconomic policy has been towards minimalism. In the optimistic Keynesian phase of the 1960's, it was assumed that both fiscal and monetary policy were effective tools for macroeconomic management. But the influence of monetarist and New Classical critiques has led to a gradual erosion of theoretical support for activist government policy. First fiscal policy fell by the wayside, perceived as too slow and possibly counterproductive in its impacts. Then New Classical and rational expectations critiques suggested that even monetary policy was ineffective. Thus the role of government policy has been reduced to a cautious effort not to make things worse -- in effect a return to an economics of laissez- faire.

4. Agriculture in a Global Perspective

Abstract:
In the twenty-first century, it is evident that world agricultural systems will have to supply sufficient food for a population somewhere between 7.5 and 12 billion. Projections for world agriculture in the first half of the twenty-first century very widely, largely depending on assumptions about yield growth. An investigation of the patterns of yield growth for major cereal crops offers evidence that the pattern is logistic, implying that an upper limit to yields is being approached. This pattern is consistent with ecological limits on soil fertility, water availability, and nutrient uptake. It is also evident that current agricultural production is imposing serious strains on ecosystems, with widespread soil degradation, water overdraft and pollution, and ecological impacts such as loss of biodiversity and the proliferation of resistant pest species.

5. Basic Principles of Sustainable Development

Abstract:
Great ideas are usually simple ideas. While the specific analysis of any important topic will necessarily involve complexity and subtlety, the fundamental concepts which underlie powerful paradigms of thought are usually relatively straightforward and easy to grasp. In the area of social science, ideas which affect millions of people and guide the policies of nations must be accessible to all, not just to an elite. Only thus can they permeate institutions from the local to the global level, and become a part of the human landscape, part of the fabric within which we define our lives.
