AGRICULTURE AND THE ENVIRONMENT
Ecology is now a central theme of the American
people, and concern over and the solution of pollu­
tion problems are vital for the long-term quality of
life. Agriculture, along with several other industries,
has been singled out as a major source of environ­
mental pollution. Although agriculture was one of
the last industries to be popularly targeted as a
major source of pollution, agriculture, like most
other targeted industries, reacted with indignant
denial. There is some basis for agriculture’s denial,
moreover, since the topic of environmental pollution
has been subjected to some elements of exaggeration
and overreaction.
Farmers were among the first to recognize the
symbiotic relationship between man and his envi­
ronment. Their everyday contact with and depend­
ence on the environment forced farmers to become
conservationists. As a result, farmers adopted crop
rotation, contour farming, and other techniques that
helped maintain the natural environment. Since all
changes are stimulated by the awareness of a par­
ticular need, the problems that stimulated farmers
to adopt most of their early conservation efforts
were identified only within the farming sector. Being
often unaware of new techniques adopted, society
neither condemned nor applauded these efforts.
However, recent problems have also been identified
by nonfarmers, a fact which has caused a greater
polarization between producers and consumers
and may limit the flexibility of solutions to these
problems.
Factors affecting the present situation
The major cause of agricultural pollution has
been the lack of knowledge by either farmers or
society as a whole as to the effects of various tech­
nologies on the environment. D D T was known to
be beneficial in the control of insects, fertilizers con­

tributed to better yields, and large feedlots pro­
duced meat more efficiently. No one knew the long­
term effects of DDT, fertilizer leaching into streams,
or the high concentrations of livestock wastes.
The competitive market and consumers have both
contributed to the situation since only the most
efficient producers could compete and only high
quality products would be accepted. Because of
market demands any farmer who failed to use the
latest technologies lost either his profitability, his
market, or, in fact, both.
The resulting dilemma is an agricultural produc­
tion structure that is the creation of a competitive
market, tuned to consumer demands, and based on
technologies that have recently been denounced as
detrimental to the total environment. What can be
done to resolve the problem?
Possible solutions
One suggestion is the immediate cessation of all
agricultural technologies that cause pollution. At
first glance, such a solution seems desirable. But
what would be the effects? Texas A&M University
has estimated that the withdrawal of all agricultural
chemicals alone would result in a 36 to 47 percent
decline in yields per acre of major crops. With such
supply changes, current price elasticity models are
not reliable. But estimates indicate a possible three­
fold increase in food prices along with general food
shortages and lower qualities if agricultural chemi­
cals were withdrawn from use.
While ecology is an important goal, there are
short-run as well as long-run necessities and priori­
ties to consider. Ample supplies of food of both high
quality and at low cost must be maintained. Any cut
in supply, with a resultant price increase, would have
regressive and immediate impact on all consumers.
Therefore, an alternative solution is necessary.

While lack of awareness of actions detrimental to
the environment was a major contributor to the cur­
rent ecological crisis, awareness of the problem is
the first step toward a solution to the problem.
Given this awareness, the agricultural sector can
proceed toward a solution. A total assessment of the
situation must be made. Where possible, immediate
elimination of harmful procedures or chemicals
should be achieved, with acceptable substitutes
being initiated. Where acceptable alternatives are
not available, more judicious use of harmful chemi­
cals, for instance, can minimize the damaging effects
until new alternatives are developed. However, any
of these steps have the inherent potential of in­
creased production costs. These are costs that
society has not recognized before because the envir­
onment was not considered in the past. Now that
environmental quality is included in the considera­
tion of production costs, consumers will necessarily
have to bear this cost.

Current efforts
Research on the use of chemicals, especially pesti­
cides and herbicides, indicates less extensive use
more carefully applied in timing and location can
achieve equal results. Similar results are being
found with fertilizers, and it has been noted that
nitrogen, under normal conditions and use rates,
is not subject to extensive leaching. Numerous b io ­
logical controls of insects are being advanced. These
biological controls are usually natural enemies of
the destructive insects or reproduction controls.
Efforts to totally eradicate insect pests, such as
the boll weevil, are also under way and would elim­
inate the need for pesticides. Better designed feedlots are assisting in livestock waste problems, and
use of these wastes for crop production is being
advanced. Silt control is being advanced, and ex­
tensive research for improved, less persistent chem­
icals is under way.

The impact
The first reaction by farmers was that any
changes would be impossible or prohibitive in cost,
but some of the steps already taken indicate this is
not always the case; i.e., better chemical application
saves farmers money. Other changes, such as live­
stock waste control with lagoons with graded or
paved pens, have had indirect benefits of improved
weight gains and less cattle stress due to mud and
water. Several feedlots are using pen runoff to
bring previously unproductive land into production.
These are benefits and improvements that the
mere recognition of the problem has achieved. How­
ever, the total solution of agricultural pollution is
possible only through concerted and united efforts
of all people concerned.

actual support rate, to be based on the August 1
parity price, will probably be higher. This should
provide relief to rice farmers until either domestic
or export markets pick up.

RICE PRICES HOLD UP
Despite reduced demand, the high quality of the
1970 crop and higher support rates than in other
recent years have kept rice prices high in the 1970-71
season. Although domestic use has remained about
even with last year’s level, exports are below the
record levels of recent years.
The carry-over this summer is expected to be
about 16.4 million hundredweight, approximately the
same as last year’s. This amount would be substan­
tially above carry-overs in the years prior to 1970.
The slowdown in exports and the large domestic
carry-over is due to a record world rice crop last year
and expectations of a 2-percent increase this year.
Not only have import demands of many rice-deficit
nations been reduced but areas such as South Amer­
ica, Japan, and the Philippines have entered the
export market. The USD A expects 1971 prices in
Southeast Asia, the major export market, to be be­
low last year’s relatively low level.
The minimum support price for 1971-crop rice
will be $4.93 per hundredweight. However, the

RURAL-TO-URBAN MIGRATION
CONTINUES IN TEXAS
During the past ten years, the population of
Texas increased from 9,579,677 to 11,196,730, a
16.9-percent increase. Texas grew substantially
faster than the nation as a whole and became the
fourth most populous state in the nation. However,
this growth was not evenly distributed within the

state. In fact, 146 Texas counties had population
declines, while another 51 had net out-migration
between 1960 and 1970.
The rural-to-urban migration phenomenon con­
tinued to be a very important fact in Texas as only
a few rural counties in the Panhandle and along the
Rio Grande showed absolute growth. In several of
the areas, the high growth rate is due to the ex­
tremely small population base in 1960; for example,
Brewster County grew from 6,434 to 7,780. How­
ever, several major urban counties and cities, such
as McLennan County and Waco, had population
declines during the decade of the sixties.
In fact, over 85 percent of the population growth
in Texas during the 1960’s occurred in the five
standard metropolitan statistical areas of Austin,
Dallas, Fort Worth, Houston, and San Antonio.
Many of the other counties showing absolute popu­
lation growth bordered on these SMSA’s.
Population changes occur in two ways: natural
changes due to births and deaths and changes by
migration either into or out of an area. Four differ­
ent classes of counties according to population
change have been identified in Texas: (1) those
with population declines, (2) those that had popu­
lation increases smaller than the natural growth
rate established by subtracting deaths from births—
or from 0 to 13.2 percent, (3) those showing growth
rates greater than the natural growth rates but less
than the state average, or between 13.3 and 16.8
percent growth, and (4) those having growth rates
greater than the state average or more than 16.9
percent growth during the 1960’s.
The first two groups of counties experienced out­
migration while the second two groups experienced
in-migration. The question that must be answered
is why there is such a difference among the counties.
A recent study by the Federal Reserve Bank of
Dallas established that the major determination of
migration was job opportunities and wage differen­
tials. Between 1958 and 1968 the average rural
county had a net decline of 8 percent in the total

number of jobs available. This decline was primarily
due to a decline of some 150,000 agricultural jobs.
At the same time, urban incomes were averaging
more than 40 percent more than rural incomes in
general and 60 percent more than agricultural
workers.
Any change in these migration patterns depends
on the growth of employment in the counties suffer
ing from job scarcity, especially the rural counties.
The wage differentials can be expected to provide
incentives to new plants to locate in the rural areas
However, until more job opportunities are available
to rural residents and the wage differentials narrow-,
rural-to-urban migration will continue.
