11. Agriculture in a Global Perspective

Content Type:
Working Paper
Institution:

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.

12. Civil Economy and Civilized Economics: Essentials for Sustainable Development

Author:

Publication Date:

Content Type:
Working Paper
Institution:
Global Development and Environment Institute at Tufts University
Abstract:
This essay will consider the relevance of the social sciences - especially economics - to the foundations of sustainable development. Looming environmental crises have served as a prime motivating force for reevaluating fundamental principles. In particular, the concept of sustainability, carrying with it clear requirements for values, goals and ethics, has begun to reshape economics. The broadest conception of sustainability is found if we understand sustainable development to mean Socially And Environmentally Just And Sustainable development - "SAEJAS development".

13. Basic Principles of Sustainable Development

Working Paper
Institution:

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.

14. Trade Liberalization and Pollution Intensive Industry in Developing Countries: A Partial Equilibrium Approach

Author:
Frank Ackerman and Kevin Gallagher
Publication Date:
10-2000
Content Type:
Working Paper
Institution:
Global Development and Environment Institute at Tufts University
Abstract:
Economic theory suggests that liberalization of trade between countries with differing levels of environmental protection could lead pollution-intensive industry to concentrate in the nations where regulations are lax. This effect, often referred to as the "pollution haven" hypothesis, is much discussed in theory, but finds only ambiguous support in empirical research to date. Methodologies used for research on trade and environment differ widely; many are difficult to apply to practical policy questions.
