16. Negative Feedback Analysis

23. Positive Feedback Analysis

24. Project Summary • Building johads (check dams) is not the only factor • Hill slopes are treated to stop run-off and soil erosion • Forest conservation methods have been adopted • Strong village-level organizations (gram sabhas) which tackle all issues through collective decision-making • Economic and ecologic transformation • For every Rs 100 invested in check dams the economic production in the villages has risen by as much as Rs 400 per capita per annum

25. Some Intellectual Underpinnings ofSustainable Development (And a Disclaimer)

26. Thomas Malthus (1766 – 1834)The Dismal Theory • Wrote “An Essay on the Principle of Population; or a View of its past and present Effects on Human Happiness; with an Inquiry into our Prospects respecting the Removal or Mitigation of the Evils” • He believed that population was held in check by “misery, vice, and moral restraint.” • …population, when unchecked, increased in a geometrical ratio, and subsistence for man in an arithmetical ratio.

27. And yet… • There has been a six-fold increase in global population (from 1 to 6 billion) since 1798 and still be able to more or less feed the population

28. Cornucopians“Necessity is the mother of invention” • Increase in population pressure acts as an incentive to develop new technology and produce more food • Ester Boserup concluded “that population growth naturally leads to development” • Green revolution increased grain production by 250%

29. Basic Laws of Human Ecology First Law of Human Ecology: • We can never do merely one thing- nature is interconnected • Concept of externalities Second Law of Human Ecology: • There's no away to throw to. • Concept that all resources have a purpose Third Law of Human Ecology: • The impact (I) of any group or nation on the environment is represented qualitatively by the relation I=PAT • Expansion of the 2nd Law of Thermodynamics Garrett Hardin

30. Ehrlich Identity: I=PAT • Environmental Impact is a multiplicative product from small changes in Population, Affluence and Technology • Mathematically represented as: (I + ΔI) = (P + ΔP)(A + ΔA)(T + ΔT) Divide through by the identity (1 + ΔI/I) = (1 + ΔP/P)(1 + ΔA/A)(1 + ΔT/T) Where ΔI/I, ΔP/P, and ΔT/T is the percentage increase in impact, affluence and technology

31. Quantifying Impact • Example: Lead in gasoline from 1946 to 1968 in the US • Pop. increased 42% • Vehicle mile per capita doubled • Amount of lead per vehicle mile increased 81% (I + ΔI/I) = (P + ΔP/P)(A + ΔA/A)(T + ΔT/T) (1 + ΔI/I) = (1 + 0.42)(1 + 1.0)(1 + 0.81) (1 + ΔI/I) = 5.14 ΔI/I = 5.14 – 1 =4.14 Or 414% increase in lead

32. Economics & Environmental Degradation (Kuznet’s Curve) Relationship between air pollution problems in cities and the level of development. As a city experiences development, the air pollution problems in the city increase rapidly, before stabilizing and declining as air pollution controls are implemented (Source: Based on Haq et al, 2002; Peters 2003)

33. Sustainability • Sustainability is the term designed to bridge the gulf between development and environment • Originally came from forestry, fisheries, and groundwater • maximum sustainable cut • maximum sustainable yield • maximum sustainable pumping rate • However, even when these maxima were achieved the ecosystem was not necessarily itself sustainable • The attempt now is to apply the concept to all aspects of development simultaneously

34. Savings is the Key to Sustainability d M KM d N KN d H KH S + + > = y y y y Savings as percentage of GNP Depreciation of Human Knowledge Depreciation of Man-made Capital Depreciation of Natural Capital > = + + • Weak Sustainability requires the sum of all forms of capital to • be constant or increasing over time • Strong Sustainability requires each component to be • constant or increasing over time

35. 9 Ways to Achieve Sustainability • Leave everything in its pristine state or return it to its pristine state. • Develop so as to not overwhelm the carrying capacity of the system. • Sustainability will take care of itself as economic growth proceeds. • Polluter and victim can arrive at an efficient solution by themselves.

36. Let the markets take care of it. • Internalize the externalities. • Let the national economic accounting systems reflect defensive expenditures. • Reinvest rents from non-renewable resources (weak & strong sustainability). • Leave future generations the options or the capacity to be as well off as we are.

37. The Debate Continues • In this course our goal is to avoid the major intellectual perils at both ends of this debate. • We must evaluate what we know and have experienced and what is predictable and attempt to maximize benefits while minimizing harm • In the long run Malthus has to be right but in the short run can we rely on human ingenuity • Thus our definition of sustainability is time-bound to the near future
