The Government of Pakistan is currently finalizing its Poverty Reduction
Strategy Paper (PRSP) to set the stage for integrating its attempt to
reduce poverty with the process of economic growth. To facilitate a contribution
to Government policy in this area by independent economists, the Pakistan
Institute of Development Economics and the UNDP organized a symposium
last Monday. This is the second of a series of articles for the Daily
Times that briefly outline the policy paper that I presented at the symposium.
Before proposing a policy for pro poor growth it may
be helpful to identify the structural factors that constrain the capacity
of GDP growth to alleviate poverty. In last week's article we showed how
governance, inadequate health facilities, asymmetric markets and local
power structures generate poverty. In this week's article we will indicate
the institutional factors in agriculture and industry that constrain growth
and exacerbate poverty.
Institutional Factors in Slow and Unstable Crop Sector
Growth: In agriculture the average annual growth rate of major crops has
declined from 3.34% during 1980s to 2.38% in 1990s. At the same time,
the frequency of negative growth years in some of the major crops has
increased. The slow down in growth and increased instability of output
in major crops has resulted in sharply increased rural poverty on the
one hand and a slow down in the export growth on the other. Underlying
this phenomenon are five major institutional constraints: (a) Reduced
water availability at the farm gate due to poor maintenance of the irrigation
system and low irrigation efficiencies of about 37%. While the availability
of irrigation water has been reduced, the requirement of water at the
farm level has increased due to increased deposits of salts on the top
soil and the consequent need for leaching. For example, according to the
government about 33 million tons of salts are annually brought into the
Indus Basin Irrigation System, out of which 24 million tons are being
retained. (b) What makes improved efficiency of irrigation even more important
is that the extensive margin of irrigated acreage has been reached, so
that future agricultural growth will have to rely on improving the efficiency
of water use and other inputs. Thus the rehabilitation of Pakistan's irrigation
system for improving irrigation efficiency has become a crucial policy
challenge for sustainable agriculture growth. (c) It is well known that
high yielding varieties of seeds gradually lose their potency through
re-use, changing micro structure of soils, and changing ecology of micro
organisms in the top soil. Therefore, breeding of more vigorous seed varieties
adapted to local environmental conditions and their diffusion amongst
farmers through an effective research and extension programme is necessary.
Yet there is no organized seed industry in Pakistan to meet the needs
of farmers for the supply of vigorous varieties of seeds even in the major
crops. In wheat, for example, the average age of seeds is 11 years compared
to an average of 7 years for all developing countries. It has been shown
that there was a sharp decline in growth of total factor productivity
in Pakistan after 1975. Pakistan's lower factor productivity growth compared
to India, can be attributed to the poorer level of research and extension
in Pakistan compared to India. (d) A new dimension to the imperative of
improving research capability in the crop sector is indicated by the possibility
of declining yields per acre related with global warming. Given the sensitivity
of wheat seed to temperature increase, even a 2-degree centigrade increase
in average summer temperatures could mean an absolute yield decline of
between 10 to 16 percent during the 21st century. With a 2.8 percent population
growth, even a decline of 5 percent in yield per acre associated with
global warming, could mean serious food deficits for Pakistan. It is,
therefore, necessary to develop heat resistant varieties of food grains.
The current ineffectiveness of agriculture research and poor diffusion
amongst farmers is a cause for concern. This is particularly so in a situation
where future agriculture growth and labour absorption will have to depend
more on input efficiency than on enlargement of irrigated acreage and
input intensification which were the major sources of agriculture growth
in the past. (e) One of the most important constraints to sustainable
growth in the crop sector is the degradation of soils, resulting from
improper agricultural practices such as: (i) lack of crop rotation and
the resultant loss of humus in the top soil; (ii) stripping of top soil
and resultant loss of fertility associated with over grazing; (iii) water
erosion along hill sides and river banks due to cutting down of trees
and depletion of natural vegetation. According to one estimate, over 11
million hectares have been affected by water erosion and 5 million hectares
by wind erosion.
2 Some Constraints to the Growth of the Large
Scale Manufacturing Sector: The large scale manufacturing sector which
historically was growing at 7 to 11% per annum is now growing at less
than 3%. The factors underlying this dramatic decline include the following:
(a) A fundamental structural constraint to industrial growth as indeed
the underlying factor in slow export growth, is the failure to diversify
exports. The large scale manufacturing sector, particularly exports are
concentrated in the traditional low value added end of textiles. (b) A
changed pattern of global demand for industrial products with a shift
towards higher value added and knowledge intensive products. Pakistan's
industrial structure was not positioned to respond quickly to these changed
market conditions. (c) An erosion of the domestic framework within which
investment and growth is sustained. This includes: (i) A continued threat
to the life and property of citizens due to a continued poor law and order
situation. (ii) High electricity tariffs, relatively high interest rates
(though these have fallen this year), (iii) Lack of trained professionals
especially in the high skill sector, (iv) An inadequate technological
base through which industry can respond in a flexible way to changing
patterns of demand, (v) An adverse policy environment in the past within
which tariff and export incentives were distorted against those entrepreneurs
who were seeking to improve quality and productivity for export growth,
(vi) Dumping of smuggled, poor quality and extremely low priced imported
goods which are in many cases counterfeit copies of branded Pakistani
manufactured goods.
It is clear from our analysis that structural factors
in the practice of power, the functioning of markets and the institutional
framework of agriculture and industry, constrain both the level of growth
as well as its capacity to reduce poverty. A policy of pro poor growth
if it is to go beyond mere slogans, will have to seriously address each
of the five structural constraints we have identified.
