Title: Has Population Growth Improved the Land Quality in Africa?


1
Has Population Growth Improved the Land Quality
in Africa?
  • Lindsay Winstead
  • David Horlacher
  • Econ 428

2
Thomas Malthus
  • Pessimist
  • population increases ? degradation of land
    quality
  • CHAIN labor force increases ? average wage per
    worker decreases ? decreases living standards ?
    insufficient land quality
  • new labor hands cannot keep up with increased
    mouths to feed ? output declines

3
VS. Ester Boserup
  • Optimist
  • population increases ? enhancement of land
    quality
  • CHAIN increases population levels ? increases
    able workers food and land scarcity ? new
    technologies invented ? improve agricultural
    innovations ? improve land quality
  • necessity the mother of invention

Machakos District, Kenya

STUDY
  • Machakos district, Kenya
  • African farmers are rational, resourceful
    managers who response positively to
    incentives.
  • (Siedenburg, 2006)
  • ?

6
Infrastructure
  • Due to roads cheap interaction coasts, people
    were able to travel more easily to exchange ideas
    ? more educated on topics that stimulate
    innovation ? developed agricultural techniques

7
Innovation
  • Population increased ? increased interaction ?
    stimulates innovation, which produces new types
    of land management

8
Technology
  • Intensification of technology, due to increased
    circulation ? connects the enlarged labor force
    to land investment ? permanent cultivation
    improvement

9
Agricultural Techniques
  • Agricultural techniques plow, bench terracing,
    and manure ? increased land quality due to
    greater efficiency

10
Value and Investment
  • Population growth decreased the availability of
    soil ? greater value embedded within land ?
    stronger incentive to cultivate land
  • Wise investment is the main source of growth
  • 1. Livestock
  • 2. Labor

11
Contradicting Views
  • In Machakos study.
  • 1. an irregularity may have occurred during this
    period
  • 2. the selection of crop choice may have skewed
    reference price
  • 3. data may have been recorded unevenly
    throughout the regions

12
CONCLUSION Machakos Study
  • Increases in population growth ? increases in
    land quality
  • Optimistic view Boserupian Theory
