Thomas Robert Malthus: “The Principle of Population“

In 1798, Malthus (*1766, 1834), an English economist, wrote in his “Essay on the Principle of Population”: “Population, when unchecked, increases in a geometrical ratio, but subsistence increases only in an arithmetical ratio.“

Thomas Robert Malthus: “The Principle of Population“

This publication roused a storm of controversy. Malthus failed to foresee the astonishing development of transport and colonisation which took place in the 19th century and which increased so enormously the area from which foodstuffs and raw materials could be drawn. With the advent of the progressive agribusiness (“Post-war Green Revolution”), the use of synthetic fertiliser, pesticides, state-of-the-art irrigation systems and today the genetic engineering were the driving forces for the exponential growth of the food production.

But today, 200 years later, Malthus’ theory wins a certain confirmation, because the number of malnourished people is growing. The world population growth is outpacing the food supply.

Arable Land

Of the earth’s 149 million km² of land, approximately 17.3 million km² are cultivated.

Arable land: 10.6 % = 15.8 mill. km² Planted with permanent crops: 1.0 % = 1.5 mill. km²

Arable land is land cultivated with crops that are replanted

after each harvest, like all sorts of grains, sugar or cotton. (= annual plants)

Permanent crop land is land cultivated with crops that are

not replanted after each harvest, like citrus, coffee or rubber. (= perennial plants)

The remaining 132 million km² are permanent pastures, forests, barren land and built-on areas.

Loss of Arable Land

Arable land is currently being lost at the rate of 10 to 20 million hectares per year, caused by desertification, salinisation and urbanisation. Urbanisation alone is responsible for about

3 - 4 million hectares

In 1960 worldwide approximately 4,400 m² of arable land per capita was available, 30 years later merely 2,700 m² and in 2025 most probably only 1,700 m².

Agricultural land is constantly losing soil and fertility,caused by wind and water erosion, nutrient depletion and chemical pollution..

Agricultural Yields

Future production increases can only be reached by an enhancement of the yield per area and not by an expansion of the area.

Intensification of the production requires a much higher input of inorganic fertilisers and pesticides as well as a substantial improvement of the irrigation systems. But ironically all these efforts decrease the yields in the long run.

With an ecological cultivation the inputs of synthetic fertilisers and pesticides can be reduced or avoided, but the yields will be much lower.

Page 11: The Cellulose Gap

Yield / Genetically Modified Crops

The only practical method to reduce the input of pesticides and to increase the yield at the same time is the use of genetically modified crops. Several of the important crops are already genetically engineered

soybeans, maize, cotton and canola (a variety of rapeseed).

Genetic engineering is an absolute necessity for the nutrition and for the environment !!

Genetically Engineered Crops

Genetic engineering offers faster crop adaptation as well as a more biological, rather than a chemical approach to yield increases. Refusing genetic engineering makes the food problem even more daunting. People have been genetically modifying plants for more than 10,000 years.

“Genetic engineering is nothing else as the shortening of the evolution.”

Conclusion

In the near future we will have a desperate shortage of fertile farmland.

Arable land on which non-food crops are growing today has to be used more and more for food crops in the future. Food crops should be used for feeding people, not for

animal feed or bio-fuels.

Cotton: Harvested Area 1945/46 – 2010/11 Over the last 60 years the area – on which cotton was grown – fluctuated between 29 and 36 million hectares. The area will be dependent upon the prices for food and cotton, but will certainly shrink in future.

arable land is declining or deteriorating

land loss and soil degradation

area for food has to be expanded the cotton production sinks because more and

more farmers decide to cultivate plants which contribute to the nutrition and bring higher and primarily safer incomes

In future less land will be available for cotton growing !!

Fibre Production

The per capita fibre consumption will grow.

The production of natural fibres will remain constant or shrink.

The growth of total fibre consumption can only be covered by man-made fibres.

Certain properties of cellulosic fibres cannot be substituted by petroleum-based synthetics (Polyester, Polyacrylonitrile, Polyamide, Polypropylene and others).

Cellulosic fibres (cotton and man-made cellulosic fibres) will

make up 33 – 37% of the fibre market.

Man-made Cellulosic Fibres as a Substitute of Cotton

Cotton and man-made cellulose fibres are hydrophilic and stand for absorbency and breathability. These inherent physiological fibre properties are ideal for the moisture management. The fibres can absorb sufficient moisture, which they then release into the surrounding air. This function ensures an adequate temperature balance on the skin, especially where textiles touch the skin. For these reasons cellulosic fibres are ideal in various fields of application in textile and garment industry for

woven and knitted fabrics

Man-made cellulose fibres are an ideal substitute for cotton !!

A sustainable fibre production tries to achieve three goals

to effect the environment in a positive way ( ecology), to be economical and profitable ( economy) and to enhance the quality of life ( social responsibility).

In all three fields man-made cellulose fibres show better results than cotton.

Sustainability of Cotton

The sustainability of cotton is strongly dependent on

consumption of pesticides and fertilisers gene-modified cotton (70%) or conventional cotton (30%)

with different cultivation system • conventional • IPM (Integrated Pest Management) • organic (<1%)

water consumption rain-fed (<40%) irrigated (>60%)

• 97% flood or furrow irrigation (20-50% water efficiency) • 2% mobile irrigation systems (80-90% water eff.) • 1% drip irrigation (90-98% water eff.)

land use (resp. yield) but in comparison to man-made cellulose fibres – like Viscose, Lyocell or Modal – cotton is not sustainable at all.

Franz Martin Haemmerle

Sustainability of Cellulosic Fibres

Fibres with prefixes as “eco-”, “bio-”, “natural-” and “organic-” are not always sustainable. For example water consumption is not a criterion for the certification as organic cotton. This proves that even “bio” is not unavoidable “eco”. Life cycle analyses also show that man-made cellulosic fibres have much smaller carbon footprint compared to cotton. For the production of man-made cellulose fibres no pesticides and synthetic fertilisers are needed. The natural origin of man-made cellulosic fibres from the renewable resource wood contributes to a sustainable future.

The substitution of cotton by man-made cellulose fibres is also a contribution to environmental protection !!

More than 70 per cent of world freshwater consumption is used for irrigation and 60 per cent of the irrigation water is wasted due to inappropriate techniques. Intensive irrigation, especially flood or furrow irrigation, can cause waterlogging with a catastrophic long-term effect, salinisation. Approximately one third of the world population suffers from water shortage today, up to the year 2025 this share most likely will expand to two thirds and the number of conflicts between different countries is likely to rise.

One of the biggest environmental disasters was caused by cotton. The Aral Sea was the 4th biggest freshwater sea on earth, which has nearly disappeared over the last three decades, by using the water of the rivers for irrigation.

Compared to cotton cultivation, the yield of cellulose fibre from Central European beech forests and from fast-growing eucalyptus is much higher.

Final Conclusion

Companies which today are using mainly cotton will have to add man-made cellulose fibres to their production programme.

Man-made cellulose fibres are in contrary to cotton extremely sustainable fibres.

In comparison to cotton man-made cellulose fibres have some important assets

- no arable land is necessary, the trees (eucalyptus and beeches) for

the pulp production are growing in forests or on marginal land, - less water consumption, - no input of pesticides and fertilizers.

The substitution of cotton by man-made cellulose fibres is an

important step in order to protect our environment.

Man-made cellulose fibres are real ecological fibres !!
