TO THE
TEACHER: RESOURCES INCLUDED HERE ARE
INTENDED TO GIVE YOU BACKGROUND KNOWLEDGE ON THE TOPIC OF SUSTAINABLE
DEVELOPMENT AND TO SAVE YOU TIME WHEN TEACHING THE UNIT.
This is not
meant to be an exhaustive list but should help you understand better what is
meant by "sustainable development" practices. Some of this information corresponds to Worksheet
B. Students could research and
write their essays about any of the many topics listed here.

One example
I like to give students to illustrate the many dimensions that can be taken on
by a sustainable development system is of a farming practice in some areas of
China where fish are introduced to paddy (rice) fields in the growing season
when the paddy fields are flooded. The
fish eat insects and weeds which can damage the young rice plants as well as
provide fertilizer (through their wastes) for the plants (eliminating the need
for chemical pesticides, herbicides, and fertilizer). In addition, rice yields are improved because of the Ònatural
fertilizerÓ provided by the fish wastes, and farmers have an additional source
of income when they sell the fish at the end of the growing season when fields
are drained. (A page summarizing the
economic results of such a system is included in the source materials file in
FLB 2024 with the article titled ÒSustainable Agricultural Development in China.Ó)
Although
most of the illustrations included here relate to environmental issues, the
concept of sustainable development can be applied more broadly to include any
type of development practice which can be sustained over time. See the IISD Web site for some more
philosophical applications of Sustainable Development ideas.

What is the DEFINITION
of SUSTAINABLE DEVELOPMENT? How
does Sustainable Development relate to Economic Development?
(Pay
particular attention to the discussion of the UN International Conference and
the interview with Mrs. Brundtland of Norway.)
1987: World
Commission on Environment and Development
poverty is a
threat to the environment
idea that
economic growth can be compatible with caring for the environment =
sustainable development
"Sustainable
development is development that meets the needs of the present without
compromising the ability of future generations to meet their own needs."
Additional
definition (not in videotape):
ÒTo be
sustainable, development must improve economic efficiency, protect and restore ecological
systems, and enhance the well-being of all peoples.Ó

Worksheet E (part 2) - Sustainable Development
Gregersen, H.M. (1988). People,
trees, and rural development: The role of social forestry. Journal of
Forestry, 86(10), 22-30.
NOTE:
Don't expect your students to find everything listed here. Some points are more obvious in the text
than others.
Background
on Social Forestry
SOCIAL
FORESTRY "refers to a broad range of tree- or forest-related activities
undertaken by rural landowners and community groups to provide products for
their own use and for generating local income." p.23
Important
in social forestry programs: "sustainable, productivity-increasing
technologies that are adaptable to local circumstances and acceptable to local
populations." p.23
"The
basic issue in social forestry is how to change land use so that people get
what they need on a sustainable basis from a relatively fixed or even shrinking
land base." p.27
1. List
the countries mentioned which are using some sustainable development practices.
Korea India Haiti Brazil Nepal
Costa
Rica Nigeria Ecuador Sierra Leone Senegal
Philippines Thailand Kenya Jamaica
2. What
are the problems in these countries which sustainable development is designed
to address?
fuelwood
scarcity (can't cook or heat homes)
unemployment
population
growth = increased needs for fuelwood
and agricultural land
deforestation
and forest & environment degradation
3. What
examples of sustainable development are given in the articles?
SOCIAL
FORESTRY
reforestation
community
fuelwood plantation
planting
trees along fields (fence, windbreak, fuelwood)
intercrop
trees with food crops
training
in agroforestry & agroforestry research
upland
land use and watershed management (TFAP p.27)
conservation
of tropical forest ecosystems
forest-based
industrial development
4. What
advantages and benefits of sustainable development are mentioned?
improve
environment (e.g. improved soil fertility)
increase
food and energy security
decrease
unemployment
[See
graph p.24]
increase
crop productivity
increase
livestock production and control (fence around livestock)
windbreaks,
shade
tree
products for consumption or sale:
fruit
wood for building, fencing, fuel
improve
livelihood of poor rural people:
income from tree products
soil improvement
food
supplements
local
community development
5. What
disadvantages or limitations of sustainable development, if any, are mentioned?
need judgment in deciding
how and when to integrate trees into farming systems because trees can compete
with agricultural crops
sometimes difficult to
promote local participation (people must have the resources (i.e. land),
knowledge, incentives, and support for efforts to succeed) p.27-28
sometimes,
because of population pressure, land not available for trees
sometimes
limited availability of appropriate seedlings
assistance and incentive
programs need to be managed well to avoid dependence on outside resources
lack of government support
can make implementation and sustainablity of social forestry programs difficult
benefits
of such programs are not immediately visible(they are long term)
6. What
SDW and/or MSW values and beliefs seem to underlie the situations and practices
discussed in the article? (refer back
to Tables 1 and 2)
People
are allies with nature
People
consume "too many" natural resources (without replacing them)
People
work to achieve community goals
(yet also MSW: Economic
development based on seeking self-interests)
Through economic growth,
people can rise above poverty MSW (sort of implied)
Needs
of future generations
Localized development
policies and programs (but foster top-level support too)
Emphasize
localized self-sufficiency
