Title: Chapter 4 Resources and Environment Learning Objectives:


1
Chapter 4 Resources and EnvironmentLearning
Objectives
  • World resources nature, distribution limits
  • Global food problems their nature extent,
    difficulties in their solution
  • Strategic minerals distribution supply
  • The energy crisis causes, consequences and
    alternative energy options
  • Nature and causes of environmental degradation

2
Thinking about the organization of this textbook
  • First, a broad discussion of resources
  • Then, a detour into theory (finally)
  • Followed by a treatment of industry, progressing
    from activities absorbing natural resources
    through service industries
  • Cast in space in cities, and in systems of
    trade
  • First, though, let us think about the broad
    sectors of economic activity

3
The Economic System An Industry Perspective (Fig
8.2)
  • Primary agriculture, fishing, forestry, mining
  • Secondary Manufacturing, Construction
    Utilities
  • Tertiary Transportation, Trade, Business
    Services, Consumer Services, Public Services
  • Quaternary ? Elements of tertiary except the
    channel of distribution (trade, transport)

Foundational Issues and Resources and Population
  • The constant specter of Malthus warning-Katrina
    oil
  • Resource optimists vs. resource pessimists
  • The text contrasts a carrying capacity
    (?sustainable development?) versus overpopulation
    approach to development
  • Patterns of growth with benefits to all, not just
    elites
  • Carrying capacity under particular technologies
  • Alternatives to the current Western energy
    material intensive production systems, based on
    (1) sun-based organic agriculture, (2) renewable
    energy sources, (3) greater reliance on local raw
    materials labor intensive technologies, and (4)
    decentralized production to increase local
    self-reliance and reduce transport activity

Contrary to current institutions

Types of Resources and Their Limits
Entire Stock
Nonrenewable Vs. renewable Resources. Renewable St
ocks (soil) Vs. renewable Flows
(water) Maximum Sustained yield Tragedy of
the commons
?Cost Of Use?
For a specific Time period
Natural resources have meaning only in terms of
historically-specific Technical and cultural
appraisals of nature. p. 99
9
Food and Population
Globally food production has kept pace with
population. Africa with major food supply
problems elsewhere problems of equity In food
supply distributions and nutritional quality.
Obesity

Food and Population
11
Developing Countries With Food Security Issues
12
Food Resource Issues
  • Urbanization food supply patterns
  • Poverty esp. in Africa other LDCs. Chapter
    14 revisits this topic under-nutrition chronic
    malnutrition
  • Population Growth Food Security issues
    problems of transport, marketing and storage,
    mismatch between where grain supplies are
    produced and needed
  • Civil Unrest and War
  • Environmental Decline desertification
    deforestation
  • Government policy and debt

World Desertification multiple causes ?Role
of Global Warming?
24
Increasing Food Production
  • Expanding Cultivated Areas
  • Theoretically about 2X current area, but major
    environmental issues (desertification,
    deforestation, related climate change)
  • Raising the Productivity of Existing Cropland
  • Green Revolution inequitable pattern. Figure
    4.9
  • Other factors- aquaculture, development of
    high-protein cereals, more efficient use of
    certain foods
  • Concerns about genetically engineered seed stocks
  • How to institutionalize more sustainable
    agriculture?
