Wild Foods of Australia

Over 120 years ago, the English botanist J. D. Hooker, writing of Australian edible plants, suggested that many of them were ‘eatable but not worth eating’. Nevertheless, the Australian flora, together with the fauna, supported the Aboriginal people well before the arrival of Europeans. The Aborigines were not farmers and were wholly dependent for life on the wild products around them. They learned to eat, often after treatment, a wide variety of plants.

The conquering Europeans displaced the Aborigines, killing many, driving others from their traditional tribal lands, and eventually settling many of the tribal remnants on government reserves, where flour and beef replaced nardoo and wallaby as staple foods. And so, gradually, the vast store of knowledge, accumulated over thousands of years, fell into disuse. Much was lost.

However, a few European men took an intelligent and even respectful interest in the people who were being displaced. Explorers, missionaries, botanists, naturalists and government officials observed, recorded and. fortunately in some cases, published. Today, we can draw on these publications to form the main basis of our knowledge of the edible, natural products of Australia. The picture is no doubt mostly incomplete. We can only speculate on the number of edible plants on which no observation was recorded.

Not all our information on the subject comes from the Aborigines. Times were hard in the early days of European settlement, and traditional foods were often in short supply or impossibly expensive for a pioneer trying to establish a farm in the bush. And so necessity led to experimentation, just as it must have done for the Aborigines, and experimentation led to some lucky results. So far as is known, the Aborigines made no use of Leptospermum or Dodonaea as food plants, yet the early settlers found that one could be used as a substitute for tea and the other for hops. These plants are not closely related to the species they replaced, so their use was not based on botanical observation. Probably some experiments had less happy endings; L. J. Webb has used the expression eat, die, and learn in connection with the Aboriginal experimentation, but it was the successful attempts that became widely known. It is possible that the edibility of some native plants used by the Aborigines was discovered independently by the European settlers or their descendants.

Explorers making long expeditions found it impossible to carry sufficient food for the whole journey and were forced to rely on, in part, on food that they could find on the way. Still another source of information comes from the practice in other countries. There are many species from northern Australia which occur also in Southeast Asia, where they are used for food.

In general, those Aborigines living in the dry inland areas were largely dependent for their vegetable foods on seeds such as those of grasses, acacias, and eucalypts. They ground these seeds between flat stones to make coarse flour. Tribes on the coast, and particularly those in the vicinity of coastal rainforests, had a more varied vegetable diet with a higher proportion of fruits and tubers. Some of the coastal plants, even if they had grown inland, probably would have been unavailable as food since they required prolonged washing or soaking to render them non-poisonous; many of the inland tribes could not obtain water in the quantities necessary for such treatment. There was also considerable variation in the edible plants available to Aborigines in different latitudes. In general, the people who lived in the moist tropical areas enjoyed a much greater variety, than those in the southern part of Australia.

With all the hundreds of plant species used for food by the Australian Aborigines, it is perhaps surprising that only one, the Queensland nut, has entered into commercial cultivation as a food plant. The reason for this probably does not lie with an intrinsic lack of potential in Australian flora, but rather with the lack of exploitation of this potential. In Europe and Asia, for example, the main food plants have had the benefit of many centuries of selection and hybridization, which has led to the production of forms vastly superior to those in the wild. Before the Europeans came, the Aborigines practiced no agriculture and so there was no opportunity for such improvement; either deliberate or unconscious, in the quality of the edible plants.

Since 1788, there has, of course, been an opportunity for the selection of Australian food plants which might have led to the production of varieties that were worth cultivating. But Australian plants have probably ‘missed the bus’. Food plants from other regions were already so far in advance after a long tradition of cultivation that it seemed hardly worth starting work on Australian species. Undoubtedly, the native raspberry, for example, could, with suitable selection and breeding programs, be made to yield a high-class fruit; but Australians already enjoy good raspberries from other areas of the world and unless some dedicated amateur plant breeder takes up the task, the Australian raspberries are likely to remain unimproved.

And so, today, as the choice of which food plants to cultivate in Australia has been largely decided, and as there is little chance of being lost for long periods in the bush. Our interest in the subject of Australian food plants tends to relate to natural history rather than to practical necessity.

Reading Passage 2

You are advised to spend about 25 minutes on Questions 14 – 27 which refer to IELTSFever Academic IELTS Reading Test 68 Passage 2 below.

Rising Seas

Paragraph 1 INCREASED TEMPERATURES The average air temperature at the surface of the earth has risen this century, as has the temperature of ocean surface waters. Because water expands as it heats, a warmer ocean means higher sea levels. We cannot say definitely that the temperature rises are due to the greenhouse effect; the heating may be part of ‘natural variability over a long time-scale that we have not yet recognized in our short 100 years of recording. However, assuming the build-up of greenhouse gases is responsible, and that the warming will continue, scientists-and inhabitants of low-lying coastal areas would like to know the extent of future sea level rises.

Paragraph 2______________________

Calculating this is not easy. Models used for this purpose have treated the ocean as passive, stationary, and one-dimensional. Scientists have assumed that heat simply diffused into the sea from the atmosphere. Using basic physical laws, they then predict how much a known volume of water would expand for a given increase in temperature. But the oceans are not one-dimensional, and recent work by oceanographers, using a new model which takes into account a number of subtle facets of the sea-including vast and complex ocean currents-suggests that the rise in sea level may be less than some earlier estimates had predicted.

Paragraph 3_______________________

An international forum on climate change, in 1986, produced figures for likely sea-level rises of 20 cm and 1.4 m, corresponding to atmospheric temperature increases of 1.5°C and 4.5°C respectively. Some scientists estimate that the ocean warming resulting from those temperature increases by the year 2050 would raise the sea level by between 10 cm and 40 cm. This model only takes into account the temperature effect on the oceans; it does not consider changes in sea level brought about by the melting of ice sheets and glaciers, and changes in groundwater storage. When we add on estimates of these, we arrive at figures for total sea-level rises of 15 cm and 70 cm respectively.

Paragraph 4_______________________

It’s not easy trying to model accurately the enormous complexities of the everchanging oceans, with their great volume, massive currents, and sensitivity to the influence of landmasses and the atmosphere. For example, consider how heat enters the ocean. Does it just ‘diffuse’ from the warmer air vertically into the water, and heat only the surface layer of the sea? (Warm water is less dense than cold, so it would not spread downwards.) Conventional models of sea-level rise have considered that this is the only method, but measurements have shown that the rate of heat transferred into the ocean by vertical diffusion is far lower in practice than the figures that many modelers have adopted.

Paragraph 5_________________________

Much of the early work, for simplicity, ignored the fact that water in the oceans moves in three dimensions. By movement, of course, scientists don’t mean waves, which are too small individually to consider, but rather the movement of vast volumes of water in huge currents. To understand the importance of this, we now need to consider another process-advection imagine smoke rising from a chimney. On a still day it will slowly spread out in all directions by means of diffusion. With a strong directional wind, however, it will all shift downwind. This process is advection–the transport of properties (notably heat and salinity in the ocean) by the movement of bodies of air or water, rather than by conduction or diffusion.

Paragraph 6___________________________

Massive ocean currents called gyres do the moving. These currents have far more capacity to store heat than does the atmosphere. Indeed, Just the top 3 m of the ocean contains more heat than the whole of the atmosphere. The origin of gyres lies in the fact that more heat from the Sun reaches the Equator than the Poles, and naturally, heat tends to move from the former to the latter. Warm air rises at the Equator and draws more air beneath it in the form of winds (the ‘Trade Winds’) that, together with other air movements, provide the main force driving the ocean currents.

Paragraph 7____________________________

Water itself is heated at the Equator and moves poleward, twisted by the Earth’s rotation and affected by the positions of the continents. The resultant broadly circular movements between about 10 and 40°North and South are clockwise in the Northern Hemisphere and anticlockwise in the Southern Hemisphere. They flow towards the east at mid-latitudes in the equatorial region. They then flow towards the Poles, along the eastern sides of continents, as warm currents. When two different masses of water meet, one will move beneath the other, depending on their relative densities in the subduction process. The densities are determined by temperature and salinity. The convergence of water of different densities from the Equator and the Poles deep in the oceans causes continuous subduction. This means that water moves vertically as well as horizontally. Coldwater from the Poles travels at depth—it is denser than warm water-until it emerges at the surface in another part of the world in the form of a cold current.

Paragraph 8 HOW THE GREEN HOUSE EFFECT WILL CHANGE OCEAN TEMPERATURES. Ocean currents, in three dimensions, form a giant conveyor belt’, distributing heat from the thin surface layer into the interior of the oceans and around the globe. Water may take decades to circulate in these 3-D gyres in the top kilometer of the ocean, and centuries in the deeper water, With the increased atmospheric temperatures due to the greenhouse effect, the oceans’ conveyor belt will carry more heat into the interior. This subduction moves heat around far more effectively than simple diffusion. Because warm water expands more than cold when it is heated, scientists had presumed that the sea level would rise unevenly around the globe. It is now believed that these inequalities cannot persist, as winds will act to continuously spread out the water expansion. Of course, if global warming changes the strength and distribution of the winds, then this evening-out’ process may not occur, and the sea level could rise more in some areas than others.

Fermented Foods for Babies

Malnutrition during weaning age-when breast milk is being replaced by semisolid foods-is highly prevent in children of poor households in many developing countries. While the etiology is complex and multifactorial, the immediate causes are recognized as feeding at less than adequate levels for child growth and development, and recurrent infections, including diarrhoea, resulting mainly from ingestion of contaminated foods. As a result, many young children, particularly between six months to two years of age, experience weight loss and impaired growth and development.

Studies by investigators in various countries have concentrated on traditional food preparation methods and have resulted in offering cheap and practical answers to these problems based on familiar, indigenous, and culturally acceptable home processing practices.

Two such answers have arisen. Firstly, cereal fermentation is used for reducing the risk of contamination under the existing inappropriate conditions for food preparation and storage in many households. Secondly, a tiny amount of sprouted grains flour is used in the preparation of weaning foods as a magic way to lessen the viscosity without decreasing energy density.

A method to eliminate pathogenic bacteria and inhibit their growth during storage of weaning preparations can benefit nutrition and health in young children considerably. Use of fermented foods for feeding children of weaning age appears to be an effective solution. Fermented foods have lower levels of diarrhoea germ contamination, they are suitable for child feeding, and can be safely stored for much longer periods of time than fresh foods. The practice has been a traditional way of food preservation in many parts of the world. The anti-microbial properties of fermented foods and their relative higher safety-documented since the early 1900’s-have been indicated in a number of studies.

In Ghana, it is common to ferment maize dough before cooking it as porridge. In Kenya, cereal-based porridge and milk are traditionally fermented. Preserving milk in the form of yoghurt has been known to many households living in hot climates.

What are the underlying mechanisms by which fermentation processes help to prevent or reduce contamination? A possible answer suggests that during the fermentation process foods become more acid. This explains why diarrhoea-causing bacteria are not able to grow in fermented foods as rapidly as in unfermented ones. It is also hypothesized that some of the germs present in the foods are killed or inhibited from growing through the action of anti-microbial substances produced during fermentation (Dialogue on Diarrhoea, 1990). The fermented foods can, therefore, be kept for a longer time compared to fresh ones. It has been shown that while contamination levels in cooked unfermented foods increase with storage time, fermented foods remain less contaminated.

Whatever the underlying mechanisms, the fact is that the exercise reduces contamination without adding to the household cost both in terms of time and money. Its preparation is easy. The cereal flour is mixed with water to form a dough that is left to be fermented; the addition of yeast, or mixing with a small portion of previously fermented dough is sometimes needed. The dough can then be cooked into porridge for feeding to the child.

Although beneficial, unfortunately, the practice is going out of fashion, partly because of the current emphasis on the use of fresh foods, particularly for children. For example, a study on the use of fermented foods for young children in Kenya ( Dialogue on Diarrhoea, 1990), demonstrated that while foods are still frequently fermented at home for child feeding, their use is becoming less popular, particularly in urban areas where commercial products are more available. Clearly they now need to be promoted.
