sociological perspectives(Cavenaco che Chavara)

THE FUNCTIONALIST PERSPECTIVE

An accepted premise of the functionalist position is that no human custom, institution, or

set of behavior exists in vaccuo; there must always be an interplay between, the component

elements of a social system (including the environment), and a continuing interdependence

between them is created on many different levels(Spencer, 1965: 13).

Structural functionalism seeks to describe the social system in terms of structures, mechanisms,

processes, and functions and to explain why a given structure rather than another contributes

to the satisfaction of a given functional requisite at a given time. The functionalist draws

mainly upon the ideas of the pioneer sociologists– Auguste Comte, Herbert Spencer, and Emile

Durkheim. And one of the features of a system

stressed by functionalists is its tendency toward equilibrium, or balance, among its parts and

among the forces operating on it. Human-Environment Interactions: The Functionalist Perspective

The functionalist perspective though has the following draw backs: has difficulty in dealing

with history and processes of change, has the tendency to exaggerate consensus, integration,

and stability while disregarding conflict, dissent and instability it is still a useful tool for describing

society and identifying its structural part and the functions of these parts. Functionalism

for instance, provides a “big picture” of the whole social life, particularly as it finds expressions

in patterned, recurrent behavior and institutions. The functionalist perspective can be used to

analyse various aspects of the human-environmenal tinteraction. The functionalists approach

the ecological environment by examining theinter-connections between the various parts

composing the ecosystem (Faia, 1989: 658-60).Functionalists see the ecosystem as exhibiting

a tendency toward equilibrium; in which itscomponents maintain a delicate balanced

relationship with one another. Functionalists stress that our survival depends on our ability

to maintain a precarious balance among the living and nonliving component comprising the

biosphere (Hughes, 1989: 425).The reciprocal ties that bind human beings

and their physical environment in the Sub-Saharare gion of Africa present a good example of the

human-environment interaction. This region I sfacing the danger of the growing desert causing

starvation among its people and an increase inthe death of cattles.Much of the “desertification “ is not attributableto basic climatic change, but to the overworkingof marginal lands for crops, grassing,

and firewood. The introduction of western techniques,such, as irrigation, deep plowing, and

the use of chemical fertilizers, has compoundedthe sub-African region’s problems (Tucker et

al., 1991: 299-301). The irrigated land becamewaterlogged, accumulated too much salt, and

became useless. The wells dug in the arid regionled people and cattle to congregate in the vicinity

of the wells, with the herds overgrazing thepastures and trampling the ground with their

hoofs.The most obvious impact of desertificationin addition to widespread poverty is the degradation

of a large expanse of land. This generallyleads to potential for human and animal carrying

capacity, and decline in soil fertility. Deserts areknown to be environmental extreme on their own;

human-induced desertification has the potentialto counteract any ameliorating effect of climatic

change on most deserts unless appropriatemanagement actions are taken.

The Niger–Delta (oil-producing) Region ofNigeria, presents another good example of the

human-environment interaction. The activitiesof the oil companies- Shell, Chevron-Texaco,

British Petrol among others in this region havecaused lots of damages especially pollution.

Pollution causes environmental damage andhuman health problems. On the economic side,

pollution control and clean up in this area costsmoney. And anything involving money is always

affected by politics. The interwoven roles playedby politics, the economy, human health, and the

environment will be fully analysed under theconflict and interactionist perspectives.

Expanding human activities on land and seaslead to a vicious cycle because humans intensify

their exploitation of the land in order tocompensate for desertification and pollution.

This can cause a lot of damage, thereby resultingin what Merton calls ‘dysfunction’ on the land.

To avoid this damage to the ecosystem, functionalistsemphasise that human beings must

become more sensitive to both the manifest(those consequences that are intended and

recognized by the participant in a system), andlatent (those consequences that are neither

intended nor recognized by the participants in asystem) consequences of their actions on the

environment. Such precaution will lead to a stateof balance or equilibrium.

 

 

 

 

conflictict

 

Like functionalists, conflict theorists, focus their attention on society as a whole, studying

Their institutions and structural arrangements. Table 1 presents the major dissimilarities between

Functionalist and conflict perspectives. The main source of conflict in human societies

Is scarcity of the resources people require, according to conflict perspective? Wealth, prestige,

And power is always in limited supply, so that gains for one individual or group are often

Associated with losses for others (Hughes, 1999:60). Power, the ability to control the behavior

Of others, even against their will-determines who will gain and who will lose (Laswell, 1936). Conflict theorists are concerned with how it is that some groups acquire power, dominate other groups, and affect their will in human efforts. The Human-Environment Interactions:

The Conflict Perspective Generally speaking, conflict perspective does

Not offer a unified point of view on many issues. Issues relating to environmental matters are no

Exceptions. Some conflict theorists have linked environmental problems to the distribution of

The world’s resources than to a limited amount of resources available. That is, the main issue is

Not one of how much is available but one of which individuals and groups will secure a

Disproportionate share of what is available. Consequently, the critical decisions that affect

The environment are made not in the interests of present and future generations but in the

Interests of those groups that can impose their will on others (Hughes, 1999).

From a conflict perspective people are usually separated into two camps on environmental

Matters. Those who favour economic development and growth even if it results in some

Measure of environmental damage and those who see environmental protection over economic

Goals. Although conflict theorists also see many of the same circumstances earlier discussed in

Africa in general and Nigeria in particular, they however, come to somewhat different conclusions. For instance, desertification is not blamed for Africa’s problems, but rather the growing indebtedness pressure exerted on African governments to promote cash crops for export rather

Than for food crops for their people. This phenomenon’s concisely described in the World Bank

Report in the 1980s. The Report explained the situation in five ways: one, from 1980 to 1987,

African farmers increased their food output by only 1.3 percent, less than half the rise in

Population; two, commodity prices fell simultaneously on the world market, and this

Made it impossible for African nations to repay their debts; three, much of the money provided

By Western aid agencies was diverted to highly visible projects such as roads, port facilities,

Airports, and office buildings, thereby recycling the aid money to Western corporations, to the

Neglect of the African farmers; four, even when Western nations provided funds for African governments, they have found an outlet for surplus food in need of market which has

Benefited the United States of America and European farmers; finally, assistance is often

Rendered to African governments that are friendly toward the donor nations, thus guaranteeing the stability of such ‘cooperative’ African nations (Farnsworth, 1990).

The Niger-Delta Region of Nigeria also fits into the human-environment interactions. The coastal area of Niger-Delta Region contains diverse and productive habitats in addition to

Minerals that is important for settlements, development and local subsistence. Coastal

Resources in particular are vital for many local communities and indigenous people. But what exists in the Niger-Delta Region points to the contrary. In addition to the pollution resulting

From gas flaring, degradation of the marine

Environment has also resulted from a wide range

102 O.A. OGUNBAMERUof activities on land. Human settlements, land

Use, construction of coastal infrastructure, agriculture, is affecting the marine environment.

Shipping also causes marine pollution and sea based activities. In Nigeria, for instance, marine

Pollution is basically caused by oil producing activities. The marine environment including the oceans

And all the seas and adjacent coastal areas Forman integrated whole that is an essential component

Of the global life-support and a positive asset that presents opportunities for sustainable

Development (Sumit, 1992: 139). Also in Nigeria, in addition to desertification and the hazards of oil producing activities, soil erosion, deforestation and overgrazing are adversely affecting

Productivity in the farming; forestry and livestock sectors, thereby slowing overall economic

Growth in a country that is an agriculturally based economy.There is also currently the conflict between the federal government of Nigeria and the oil producing states on one hand and the non oil

Producing states and the federal government on the other hand over the issue of ‘resource

Control’, especially as this relates to on-shore, and off-shore resources.

There was also the conflict between the federal government of Nigeria and the youths of

Bayelsa state – one of the leading oil producing states in Nigeria. Specifically, in 1999, immediately

The civilian government came to power, some youths of Odi town in Bayelsa, in agitation

For improvement of their lives, abducted and later killed some law enforcement agents. In retaliation,

The federal government sent a detachment of the army to arrest the situation, but what

Invariably happened was the destruction of Odi town by the army. So many lives were lost, and

Property and houses extensively destroyed. According to conflict theorists, expanding

Human requirements and economic activities replacing ever increasing pressures on land

Resources, creating competition and conflicts and resulting in sub-optional use of both land and

Land resources, and at times loss of lives and property as reported above. If human requirements

Are to be met in a sustainable manner, it inessential to resolve these conflicts and move

Towards more effective and efficient use of land and its natural resources. Integrated physical

And land-use planning and management is an eminently practical way to achieve this.

grazing habbits of different farm animals

Cavenaco che Chavara

 

Grazing habits of different farm animals

Grazing Habits of cattle -. As heavier animals, cows can inflict more damage onto a pasture than lighter animals such as sheep. Wet pastures are less able to bear the weight of the cow and wet pasture is more damaged than if it had been a dry field. While cows feed on the grass on the other side of a fence, they usually trample the area around the fence.

Cattle prefer longer, higher vegetation, cattle pastures tend to have less tillering. A cattle-grazed pasture will have considerable unglazed material (up to 30% of production) near dung piles and urine spots. Sheep tend to graze much of this material.

Different Forage Species Preference - Cattle prefer coarser, longer forage, whereas sheep prefer fine material.

Chewing (Cows)

Equipped with a long and dexterous tongue, the cow can wrap its tongue around plant parts and pull the food into its mouth where it is placed between its lower jaw and a pad on the upper surface. Once in the mouth, the cow swings its head to severe the plant parts and chews the food slightly, and mixes it with saliva before swallowing. Later the cow will regurgitate the food to chew and grind it again. This process is called rumination or chewing the cud. The actual chewing portion of a cow's day consumes eight hours and ruminating takes about 12 hours. Cows can take around 890 bites per hour for about 8 hours a day. Due to the design of the cow's lips, teeth, and jaw a cow can't easily get closer than 2 inches from the soil. An ideal height of grass is about 6 inches, higher or lower than that will consume more time and energy for the cow. Cows will not graze much longer than 8 hours, so grass at the proper height will increase intake and improve animal nutrition. Cows also prefer not to eat around their own paddies but are willing to graze after a different type of animal has defecated. Cows like to graze on rolling land, although they are able to graze anywhere.

Sheep and goats

 

Smaller animal species generally graze shorter vegetation.

 Sheep graze many common "weeds" even when high quality forages are available. An observation of a "sheep farm" will show clean pastures - no ironweed. Goats prefer brush, including berry and multiflora rose plants.

As lighter animals, sheep do not cause as much trampling but they can over-graze and extensively damage pastures

 

Chewing (Sheep)

While cows may best utilize their tongue, sheep use their lips and teeth as their primary forage gathering tools. Cleft lips move away from their teeth on the lower jaw and help bring food in, while the upper jaw has a dental pad that is about 1.6 inches wide. Together, the teeth on the lower jaw and the pad on the upper jaw sever the leaf blades. Such a mouth structure allows sheep to bite closer to the ground than cows and the ability to be more selective. The ideal grass height for sheep is about 4 inches.

Both cows and sheep are ruminant animals which mean they have four stomachs through which they cycle feed. This requires time for rumination or the regurgitation of the bolus that was made from bites of forage and rechewing, preparing for easier digestion. So, cows and sheep need time for both eating and ruminating. Maximum efficiency is achieved by providing abundant forage at an optimal height.

Goats

Much like sheep, goats also have teeth on their lower jaw and a strong dental pad on their upper lip. The upper lip is incredibly mobile and with the help of a strong tongue, goats can selectively grab and are able to avoid thorns and spines. Goats select woodier browse and will choose young, tender leaves and twigs, before grasses and legumes. Thus, young trees will need to be protected in agroforestry systems.

Horses

Like cows, horses are heavy animals. They tear up wet pastures easily; grasses are no match for their shoed hooves. Horses are often left outside during the winter causing their pasture to be badly damaged or transformed into mud and muck

Chewing

A horse will eat more often than a ruminant animal because it doesn't spend time ruminating, but it will eat a smaller amount per session because its stomach is smaller on a per body weight basis. Horses have upper and lower sets of front incisor teeth used primarily for biting while the back set of molars are used mainly for grinding food. A strong, sensitive, upper lip gathers the food and brings it to the incisors. Its short tongue is less essential to the eating process. The upper teeth are wider which causes wear on the teeth from grinding and sometimes there is a need for their teeth to be filed. Horses can graze a pasture to the soil level because the teeth and head can get so close to the sod. They tend to section off their pastures into eating and spoiling areas.
