HUNGRY:
AGRICULTURE AS THE VITAL LINK
INTRODUCTION
The prospects for achieving
satisfactory global living standards are threatened by environmental deterioration,
especially in the poorest countries, where agricultural and other economic
activities are most heavily dependent upon the quality of natural resources.(1)
Some of the environmental changes that are taking place as a result of
efforts to improve standards of food, clothing, shelter, comfort and recreation
have the potential to do irreversible damage to the earth's capacity to
sustain life. Meanwhile, unrestrained population growth in some developing
countries is exacerbating the deterioration of the environment.
Past scientific and technological
innovations in agriculture were able to overcome resource constraints.
It is questionable, however, that agricultural productivity can keep pace
with a rapidly growing population while protecting our global resources
and ensuring that they will provide enough food for generations to come.
The paper looks at the role
of developed countries in promoting agricultural self-reliance in the
Third World by the transfer of skills and "appropriate" technology.
It explores methods of measuring human progress using agriculture as an
indicator of the health of our planet. It suggests that current methods
of evaluating prospects for the world's food supply are inadequate.
HISTORICAL
POPULATION TRENDS
In A.D. 1, the world supported
about 300 million people. More than 1,500 years passed before the population
doubled. In the 18th century, however, births started to outpace deaths
and between 1750 and 1900 the population rose to 1.7 billion, doubling
itself in only 150 years. Population grew at 1% a year from 1900 to 1950,
after which the annual growth rate was 2%, representing a doubling of
population every 35 years.(2)(3)
Until mid-century, the rate
of population growth was approximately the same in all regions of the
world. After that time, while population in industrialized countries grew
by less than 1% a year, in the developing countries it rose by almost
3%. By 1990, of the world's 5.3 billion people, 4.1 billion, or 77%, lived
in the developing world while 1.2 billion inhabited the industrialized
countries.(4) Improved health
care and a younger population in the developing countries accounted for
this widening population gap.
By the year 2000, over 90
million people will be being added annually to the population of the developing
countries. As Table 1 shows, by 2025 the developing countries will account
for about 84% of the world's population and the discrepancy between them
and the
industrialized countries
will be even more evident, even though it is projected that a decrease
in the number of people added each year will result in a stabilization
of world population at 11.2 billion in 2100.(5)
Such stabilization will
largely depend on the success of population planning programs. While these
have been relatively successful in rapidly industrializing nations such
as Thailand, the Republic of Korea and China, growth rates in Africa,
as Table 1 shows, continue to increase.(6)
Women's access to contraception and their attitudes to birth control will
play an important part in containing population growth.

Population control through
family planning is central to the concept of sustainable development,
which is possible only if human populations are kept in balance with the
natural resources that support them. Populations can not be sustained
beyond the carrying capacity of the region; if they are not limited by
conscious human effort, they are likely to be limited by natural resource
constraints.(7)
The next sections of the
paper explore the balance of food demand and supply with a view to determining
the ability of the global village to expand its food capacity sustainably
to meet future food needs.
THE
DEMAND FOR FOOD
Only one third of the population
of developing countries live on land that produces enough food to supply
its people.(8) The rate of
population growth has a lot to do with this equation. The countries and
regions with above-average population growth and inadequate agricultural
and overall economic growth face a continuing challenge in providing sufficient
per capita food supply.(9)
Population size and density
do not per se cause natural resource degradation or hunger. Such
problems arise when the population becomes too large in relation to the
productivity of the resource base. Low population areas of the world,
such as many regions of Africa, are often areas where the resources cannot
support many people. While population is one side of the equation, land
productivity is the other. In Africa, for instance, about 80% of the continent
cannot be considered cultivable and only 7% of the arable land has productively
rich alluvial soil.(10)
Historically, a growing
population to land ratio has led to intensified production. Technological
change and modern inputs (fertilizer, improved seeds, irrigation) more
than made up for the unfavourable changes in land to people ratios. As
a result, in global terms, the rapid population growth of recent decades
was more than matched by commensurate increases in agricultural production.
The situation, however, is not so comforting in all countries and regions.
Over the last two decades, per capita agricultural production declined
in many countries, particularly in Africa, where one African in five is
now fed by imported food. This also happened in countries where there
was scope for maintaining or increasing the land to people ratios. Inadequate
infrastructure and economic incentives have impeded the advent of the
technological change that underpinned growth in other countries and regions.(11)
Declining food production per capita is one indicator that population
growth is outrunning land resources.(12)
The fundamental problem
in feeding the world's population is not inadequate capacity for production,
but unequal distribution of that capacity in relation to population. No
absolute food shortage on a global basis exists now or is projected in
the foreseeable future.(13)
Global grain production is currently more than enough to provide every
man, woman and child in the world with a daily ration of 3,000 calories
and 65 grams of protein. Yet hunger is an obvious reality in our present
world. An increase in world food production would not solve the problem
of distribution, and, by itself, would not reduce the incidence of hunger.(14)
The Food and Agriculture
Organization (FAO) has predicted that world demand for food could increase
by 50% during the next two decades and will at least double between now
and the year 2050.(15) By
the end of the century, that organization projects that one person in
six in the developing world (excluding China) will be forced to exist
on a diet inadequate for supporting a normal life. The countries of South
Asia and Africa will continue to be the most adversely affected.(16)
FOOD
SUPPLY AND THE DIMINISHING RESOURCE BASE
None of the basic resources
required to expand food production - land, water, energy, and fertilizer
- can now be considered abundant or inexpensive. In developing countries,
there has been serious degradation of arable land. Population pressures
have caused grave over-exploitation of soils. Irrigation, overgrazing,
and denudation of huge forest areas to obtain wood for fuel and to clear
land for farming have further reduced the soil's capacity to produce.
Some of this land is marginal for farming, with soil and climatic conditions
poorly suited for annual cropping.(17)
This is especially true where the more fertile lands are already crowded
and the population spills over on to marginal land. Such land can only
produce low yields and is more or less susceptible to degradation, depending
on the quality of management.(18)
According to the Worldwatch
Institute, an organization which monitors progress towards a sustainable
world, soil erosion is slowly undermining the productivity of one third
of the world's cropland. Each year, the world's farmers lose an estimated
24 billion tonnes of topsoil in excess of new soil formation.(19)
Deforestation is leading to increased rainfall run off and crop-destroying
floods.(20) Between 1970
and 1990, the world lost nearly 200 million hectares of tree cover and
deserts expanded by some 120 million hectares.(21)
The U.S. Department of Agriculture
has categorized agricultural land by degree of degradation as shown in
Table 2. The extent of degradation in the developing countries even 20
years ago was already apparent. The case of Africa is particularly disturbing,
given its growing population pressures. According to the FAO, soil erosion
could reduce agricultural production in Africa by one fourth between 1975
and 2000 if conservation measures are not adopted. Lands are farmed ever
more intensively as human numbers grow. The shifting cultivation traditionally
practised in Africa to maintain soil fertility has begun to break down
under high population densities as farmers return to the same plot every
five to ten years instead of waiting 20 to 25 years as was customary in
the past. As the following cycle shortens and the land's vegetative cover
diminishes, soil erosion and land degradation accelerate.(22)
Studies show that a loss
of one inch of topsoil can, for instance, reduce corn yields by roughly
6%. If the world is losing 24 billion tonnes of topsoil annually (as Worldwatch
estimates), it has been estimated that this would mean a grain harvest
loss of between 9 and 20 million tonnes per year. Salinity, pollution,
and global climate change are also affecting world food production. Worldwatch
estimates that these factors add up to an annual loss of 14 million additional
tonnes of grain or 1% of output.(23)
In terms of these figures, annual food aid of 10 million tonnes worldwide
would barely match production losses, let alone provide enough for expanding
populations.(24)

The provision of food to
the poorer nations will surely remain a major challenge for mankind for
many decades.(25) The Macdonald
Commission reported two trends in the global food economy in the final
quarter of the century. Fewer countries are now able to produce a comfortable
margin of excess food; and the world is depending more on North America,
particularly the U.S., for its supplies of cereals. Of the few countries
still exporting grain, Canada stands high on the list.(26)
Food production is a mainstay of our current economy.
According to the Canadian
International Development Agency (CIDA), Canada's main government body
distributing overseas aid, Canadians are the largest per capita food aid
donors in the world. Between 1978-79 and 1986-87 Canada provided 7.7 million
tonnes of cereals, plus vegetable oil, skim milk powder, pulses and fish.(27)
A study(28)
published by the FAO in 1979 projected a rate of growth of agricultural
production in developing countries of just under 4% in the last quarter
of the century. Such an annual rate of growth depended on a 7% increase
in Gross Domestic Product (GDP) rate. The 1979 study projected that, unless
the 7% growth rate was achieved, demand would outstrip supply, with the
net cereal deficit possibly rising to 91 million tonnes in 1990 and 153
million tonnes in 2000.(29)
The actual GDP increase was 3.5%.(30)
The desired growth rate
was not achieved, largely because of the world recession. The deficit
projected in 1988 for the year 2000 is, however, about that predicted
by the 1979 study for a decade earlier. Lower population and demand forecasts
contribute to the revised figure of a deficit of 95 million tonnes by
2000, as evident in Table 3.(31)
Food production in developing
countries has increased by about 3% a year over the last three decades
- more than doubling in volume, and growing about one third faster than
in developed countries, as shown in Tables 4 and 5.(32)
There has, however, been considerable variation in growth. While countries
like India and China have increased production strongly, growth in Sub-Saharan
Africa has been weak because of climate setbacks, unsettled political
conditions and government policies that have discouraged local food production.
Per capita food production has dropped by some 20% over the last 20 years.
Population continued to grow annually by 3% while food production growth
dropped to only 1.2%. Grain imports absorbed 20% of total foreign exchange
earnings.(33)
To date technological advances
in agriculture have allowed increases in food production to outstrip population
growth in many developing countries, thus helping to keep in delicate
balance the carrying capacity of the land. This may not continue to be
possible, however, unless the global village pursues sustainable directions.
The next section looks at some of the constraints that affect the ability
of developing countries to become food self-reliant.

THE
ROLE OF TECHNOLOGY TRANSFER
The approximately 880 million
Third World citizens who live in absolute poverty are primarily rural
people, overwhelmingly dependent on agriculture to eke out a marginal
existence.(34) That food
producers are among the most undernourished of the world is a particular
irony but findings confirm that, even with current levels of farming technology
and full use of all existing arable land, 50% of developing countries
lack the land resources needed to meet their people's food needs in the
year 2000.(35)
While the proportion of
the world's people living in these conditions has diminished over the
past generation, their number has actually grown. The House of Commons
Standing Committee on External Affairs and International Trade has called
this the "single greatest failure of development."(36)
The mushrooming of population
in many developing countries is putting additional stress on a global
environment already reeling under the blows of rapid and careless economic
growth in many parts of the world. Environmental recovery thus depends
on meeting the needs of the poorest people and countries.
Since most of the people
of these countries derive their livelihood and incomes from agriculture,
it is agricultural development that needs to address the basic source
of poverty and low standards of living.(37)
Within the overriding objective of increasing aggregate agricultural output
in Third World countries, a primary goal must be to improve the welfare
of rural families through enhancing the productivity of small farms and
promoting access to resources, markets, and technical assistance.(38)
The role of smallholders has tended to be underplayed in agricultural
development assistance.
It has been estimated that
only 15% of production increases in developing countries will result from
expansion of the existing cropland base; thus improved technology is expected
to have a vital role in increasing production.(39)
India is often given as
an example of successful technology transfer; over a period of 20 years,
that country has become a cereal exporter through the adoption of technological
developments such as high yield varieties of wheat and rice. Unfortunately,
high yielding varieties fulfil their potential only when cultivated in
conjunction with irrigation, pesticides, herbicides, and top-grade land.
If any of these factors is missing, the modern variety generally performs
more poorly than those it displaced. As well, genetic diversity is eroded
when a single variety replaces the hundreds of locally adapted varieties.
Monocultures of genetically uniform plants are also extremely susceptible
to disease epidemics, while genetic diversity helps plants withstand pests
and enables them to tolerate climatic fluctuations. Traditional farmers
use diversity to forestall calamity in the face of climatic or market
risk. Cultivating crops that exhibit different properties and thrive under
different conditions reduces risk. For the vast majority of farmers around
the world, reducing risks is far more important than maximizing productivity.
The question remains why
acceptance of indigenous traditional strains is not more widespread. Part
of the problem is that some perceive traditional crops as backward, and
anti-development.(40) As
well, government policies may work against relying on indigenous solutions;
for instance, credit may be available only for high-yield packages, and
traditional varieties may not be sanctioned. Land tenure may also be a
consideration. Preserving the land by less use of inputs and more use
of traditional varieties may not be a goal of either landlord or tenant.(41)
The record for the successful
introduction of advanced technologies in the Third World is very poor,
especially in Africa. The Green Revolution, so successful in parts of
Asia, did not transplant well to Africa with its fragile soils, variable
climates, and need for irrigation. African governments inaugurated a range
of projects in the 1970s aimed at increasing domestic food production.
Their mainly Western donors favoured large, mechanized, and highly capitalized
projects and crops like wheat, rice, and sugar that were preferred by
urban consumers.(42) Western
countries during this period poured $22.5 billion in economic development
aid into sub-Saharan Africa. Yet by 1986, this region required 9.6 million
tonnes of food aid a year. The reason is that only 12% of the aid reached
rural areas, and even less got to smallholders, who are thought to be
Africa's most productive farmers.(43)
In recent years, there has
been an increasing emphasis on the development of small-farm agriculture
but there remains the problem of limited adoption of introduced technologies,
termed the "technology applications gap."(44)
Agriculture is shaped by
the interaction of three basic factors: technology and resources; the
regional social, economic and political environment; and the socio-organization
of the farm.(45) In technology
transfer to small farms, an understanding of the third factor is critical
to the viability of the "improved" technology. Many new technologies
are simply inappropriate because those developing and transferring them
have an inadequate understanding of the socio-economic organization and
goals of small-farm systems.(46)
The FAO predicts that any
fundamental technological breakthroughs will encounter the typical 10-
to 15-year lag between scientific accomplishment and widespread use at
the farm level.(47) This
is a problem not only in the development context. A recent study found
that there is generally insufficient dialogue between scientists and farmers
on technological solutions.(48)
Scientists may be expert on the array of solutions to agricultural problems
and constraints and in testing technologies within specific environments.
Farm families are knowledgeable about their physical, economic, and social
environment and their farming system. They know the goals they are trying
to meet, the resources and factors of production available, and the critical
constraints and pressure points affecting production.
Uniting the two knowledge
systems is not an easy task and the mechanisms for integrating the small
farmer into the process of technology design are still experimental. However,
if technology transfer is accepted as a complex process of socio-economic
change, then there is no real alternative to it.(49)
The integration process
has been found to involve four distinct steps: learning about the client;
integrating the farming circumstances into the project process; involving
the farm family; and evaluating the adoption of the technology.(50)
Ideally, all four steps should take place in technology transfer; however,
any one would enhance the integration of the small-farm family. Such an
approach ensures defining any problems correctly, collecting all the information
needed and designing a useful response.
Integrating the perspectives
of farmers and their knowledge at an early stage in the technology design
process also helps clarify research and technological priorities. Designing
new technologies in isolation from the farming systems to which they will
be introduced often results in an application that is inappropriate for
farmers' needs. Case studies demonstrate, for instance, that the success
of development projects can be undermined by failure to recognize the
different sexual division of labour in farming for cash and farming for
food crops. If men are targeted for assistance and women do all the work,
the latter have little incentive to increase output.(51)
In other words, "small-farm producers tend to evaluate any introduced
technology in terms of its compatibility with the goals of the household
and the constraints and opportunities confronting the integrated household
system."(52)
An important related issue
is training people to adapt, innovate and invent new technologies appropriate
to their own needs and societies. Successful adaptation involves installing
technology slowly, in stages, while maintaining a continuing link between
the introduced technology and the local community; for example the local
area might provide some resource, or the process might make use of some
local knowledge.(53)
Emissions, effluents, soil
erosion and destruction of rain forests all point to the power of outdated
western technologies to wreak havoc in the south. This does not imply
that the developing world needs more sophisticated western technology.
Informed observers emphasize that the devices best placed to bring the
most spectacular gains, especially in resource conservation and reduction
of pollution, are decidedly low technology, and often pay for themselves
within a year or two.(54)
Technology transfer is consequently
not a one-way street. As Third World governments and tribal communities
realize the potential of their traditional knowledge, this will become
a potent commodity in technology transfer.(55)
The development of products and processes tailor-made for local conditions,
and the exchange of ideas between countries at similar stages of development,
may turn out to be a more promising model than blindly importing alien
western technologies. Looked at in this way, indigenous knowledge is at
least as valuable to Third World countries as western scientific skills.
The trick is to marry the two.(56)
HOW
DO DEVELOPED COUNTRIES RESPOND?
While prospects for improvement
require the governments of Third World countries to revise their policies
and accord higher priority to agricultural development, progress also
depends on the willingness of the governments of developed countries to
increase their technical and financial assistance to Third World nations.(57)
In 1987-1988, Canada's Official
Development Assistance (ODA) amounted to $2.7 billion, representing about
0.5% of GNP or about 2% of federal government spending.(58)
The goal is to achieve 0.7% of GNP by the year 2000.
In 1984, when the plight
of millions threatened with starvation in Africa came to international
attention, Canada responded generously. Canadians recognize that the alleviation
of mass hunger and poverty in less developed nations is a critical aspect
of our international relations. There was also consensus that development
in Africa is a long-term problem which cannot be alleviated solely by
short-term crisis aid.(59)
Aid can no longer be viewed
as a temporary ad hoc measure supporting a simple model of development
leading to industrial takeoff. The preceding section has emphasized that
development is not just a matter of transferring goods or technology;
questions of equity and participation must also be addressed. The poor
must become agents of their own development.(60)
Aid is at best one supporting aspect of development and cannot become
a substitute for appropriate domestic and international policies.(61)
Until recently, it has been
characteristic of developing countries to accord higher priority to industrial
development and related infrastructure than to the agricultural sector.
Since the food crisis of the early '70s, a number of developing countries
have become aware that too slow a growth in the agricultural sector holds
back overall economic growth and intensifies existing and serious social
problems.(62)
Although by the 1970s donor
nations were adopting basic human needs approaches to development assistance,
a decade later as much as 30% of bilateral aid still went to upper middle-income
countries. Aid has been least effective where it is needed most - the
poorest countries and people, particularly in Africa.(63)
Like many developed countries, Canada, in trying to run a multi-purpose
program, has fallen short in the sector most likely to help the rural
farm families who are amongst the poorest of the world's people. As Table
6 shows, about 13% of CIDA's bilateral aid went to agricultural development
and a comparable amount went to food aid.(64)
Food aid has customarily
been considered as a major policy instrument. In recent years Canada has
provided well over $300 million of food aid annually through the World
Food Program, bilateral assistance and Canadian non-governmental organizations.
Food aid has sometimes been accused of being a surplus disposal scheme
that can act as a disincentive to agricultural production in developing
countries. CIDA, however, sees it as supporting the gradual build-up of
local production and as responding to the humanitarian and balance-of-payments
problems of developing countries.(65)
Canada also supplies technical
personnel; technical assistance comes second only to education in personnel
numbers. While Canada's support for these activities has increased substantially
in the past few years, there is still room for more emphasis on human-scale
resource development that encourages the recipients to become more self
reliant, even if it inevitably brings them into competition with donor
countries.

Report, 1990-91, p. s55-s56.
Agricultural development
presents a complex area for aid activities, however well-intentioned.
The discussion above on technology transfer shows the importance of an
understanding of the socio-economic environment in which farming operates.
Other key components of successful aid programs relate to domestic policy
approaches towards both agriculture and other sector support of agricultural
goals. Developing countries' lack of institutional structures and trained
personnel can hamper aid to agricultural development. The need for effective
village-level organization for enlisting the participation of producers,
especially small farmers, in development activities has already been mentioned.(66)
In the long-run, well designed
aid programs not only have the potential to "kick-start" the
process of self-reliance in developing countries but will provide countries
like Canada -which depend so much on export growth for their survival
- with new markets for their products. Experience has shown that as the
agriculture sector is strengthened, and incomes thereby improved, consumer
expenditures on food increase sharply, resulting in substantially greater
demand for food than the increases in domestic production can accommodate.
AGRICULTURE
AS THE BELLWETHER MEASURE OF ENVIRONMENTAL HEALTH
There are weighty reasons
for emphasizing the acceleration of food production in developing countries,
most of which cannot afford and do not wish to depend on rapidly increasing
imports of food from developed countries. Farming generally looms so large
in their economies that national income can grow satisfactorily only with
good agriculture performance. Distribution improvements are said to be
easier to make when production is rising strongly rather than stagnating.(67)
The traditional method of
measuring human progress and assessing future prospects has been to use
income-based GNP (Gross National Income) and GDP (Gross Domestic Product)
performance. Ever since national accounting systems were adopted a half-century
ago, per capita income has been the most widely used measure of economic
progress. The aim of national accounting is to provide an information
framework suitable for analyzing the performance of a country's economic
system.(68)
In the early stages of economic
development, expanded output translated rather directly into rising living
standards. It became customary to equate progress with economic growth.
Over time, however, average income has become less satisfactory as a measure
of well-being. It does not reflect how additional wealth is distributed
or the environmental debt the world is incurring as the earth's natural
capital is depleted.(69)
The result is a dangerous
asymmetry in the way people measure and, hence, the way they think about
the value of natural resources. Manmade assets, such as buildings and
equipment, are valued as productive capital and are written off against
the value of production as they depreciate. Natural resource assets
are not so valued: A country could exhaust its mineral resources, cut
down its forests, erode its soils, pollute its aquifers, and hunt its
wildlife and fisheries to extinction without affecting its measured
national income. It is a bitter irony that the low-income countries
most dependent on natural resources for employment, revenues, and foreign
exchange earnings are instructed to use a system for national accounting
and macroeconomic analysis that almost completely ignores their principal
assets.(70)
With a few exceptions, only
goods and services exchanged in the market economy are included in national
income accounts, since market prices offer a means of establishing value.
While depreciation of capital assets is subtracted from GDP, depletion
of such national assets as forests do not show up as a capital consumption
or account debit. Since the basis of accounting is to measure differences
in the accounts in terms of time intervals, such an omission is not logical.
"Improving" land is included as a contribution to recorded income,
though, in fact, it may eventually destroy the income potential through
over-exploitation. As Repetto says, "The national accounts thereby
create an illusion of development, when, in fact, national wealth is being
destroyed. Thus, economic disaster masquerades as progress."(71)
Natural resources, such as the land on which agriculture depends, are
an economic asset and not a free gift of nature as their treatment in
the national accounts would suggest.
Even though the World Bank,
in its 1991 Report, equated sustainable economic development with better
living standards in the areas of education, health and environmental protection,
it continues to use economic development formulas that discourage investment
in people, health and education. GNP, GDP, inflation, interest, unemployment
and other economic indicators tend to foster a view that equates real
wealth with mere money.(72)
Slowly a recognition is
growing that we must find new ways to measure progress. Two interesting
recent developments are the Human Development Index (HDI), devised by
the United Nations, and the Index of Sustainable Economic Welfare (ISEW),
presented by H. Daly and J. Cobb in their book For the Common Good.(73)
The HDI uses longevity, knowledge and command over resources as indicators
of a good life. Statistics include life expectancy, literacy, and GDP
adjusted by purchasing power. A high average life expectancy, for instance,
indicates broad access to health care and adequate supplies of food. The
United States, which leads the world in adjusted per capita GDP, ranks
nineteenth according to the HDI measure, below such countries as Australia,
Canada and Spain.(74) The
HDI takes into account real purchasing power rather than money income
alone.(75)
According to Lester Brown
of Worldwatch, while the HDI is a more satisfactory measure of human well-being,
it does not reveal environmental degradation. The ISEW, however, takes
into account depletion of non-renewable resources, loss of farmland from
soil erosion and urbanization, loss of wetlands, and the cost of air and
water pollution. At present this index has been calculated only for the
U.S., where it shows a rise in sustainable economic welfare per person
of some 42% between 1950 and 1976 but a subsequent fall of 12% from that
level by 1988 (see Figure 1).

Costa Rica appears to be
one of the first developing countries to incorporate depreciation of natural
resources into national income accounting. As in many other developing
countries, Costa Rica'a natural resources are its most important economic
asset yet they have been seriously degraded. Cattle pasture has spread
over 35% of the land although only 8% is suitable for this use. The majority
of the territory is suited only for forests, yet only 40% remains under
forest cover.(76) Over 20
years, natural resource assets in that country valued at more than one
year's worth of GDP disappeared. This represented a 30% reduction in potential
economic growth. In 1984, for example, soil depreciation equalled 9% of
the value added in agriculture. Table 7 depicts how the inclusion of natural
resource depreciation in the national accounts provides a better indication
of the health of a nation's economy. Its inclusion reduced GDP by 9% in
1989.

et al., Accounts Overdue: Natural Resource Depreciation in Costa

If the goal of agriculture
worldwide is to meet the current generation's food needs without depriving
future generations, then we must be able to measure accurately whether
current consumption is depleting a country's productive assets at the
expense of the income of future generations.(77)
As Repetto puts it:
Past failures to prevent
natural resource degradation have already undermined efforts to develop
economies and alleviate poverty. This effect is still not recognized
by policy makers, however, who act as if natural resources were limitless
or as if technology could always replace exhausted or degraded resources.
Closer dialogue between policy makers and scientists can help dispel
this simplistic view of the natural environment. An economic accounting
system that reflects the true condition of natural resources would provide
an essential tool for the integrated analysis of environmental and economic
policies in every sector of government.(78)
If we continue to measure
human progress by GNP and GDP, we are soon likely to have a rude awakening
about our ability to feed the world's poor children. The first step is
to find out whether various regions across the world are producing food
within the carrying capacity of their national resource base. The next
step is to put in place policies for sustainable development of our food
resources so as to make possible the nourishment of future generations.
