Bioresources and biotechnologies

Vocabulary

The term “bioresources” refers to the total biological variation manifested as individual plants, animals or their genes, which could be taken by man for use as drugs, food, livestock feed, construction materials for shelter, environmental protection, etc or in the development of improved crops and animals for higher yield and tolerance to biotic and abiotic stresses. Man depends on these bioresources for his continued existence and, therefore, he must use and preserve them for future generations yet unborn. The concept of sustainable development indicates that economic and environmental protection are inextricably linked and that the quality of present and future life rests in meeting basic human needs without destroying the environment on which life depends.

The rapid diminishing rate of forests and bioresources have been variously attributed to conversion of land for agriculture, wild fires, poor management of available land, uncontrolled search for food, fuel wood, medicine, construction timber, overgrazing by cattle, displacement and loss of animal and plant species, lower yielding varieties, pests and diseases, pollution (e.g. acid rain) and incomplete knowledge of the biology of many plants especially the propagation genetics aspect and adaptability of many forest plants.

Since we cannot do without exploiting the available bioresources to our advantage, there has to be a balance between uses of resources and their conservation. In this way, we would preserve an ecosystem, which although altered would still be rich in bioresources and at the same time would provide food and other needs as well as perform vital environmental functions on a long term basis.

It is necessary to conserve these naturally endowed resources which apart from their direct usage by man, also serve several ecological functions such as the control of flood, soil erosion, landslides and hurricanes, maintenance of water quality, climate amelioration and checking desertification. Several species of birds and animals in Ukraine would have become extinct by now if not for the intervention of wildlife conservationists, as there is now greater international willingness to ‘pay’ for the conservation of biodiversity.

Biotechnology can be defined as any technique that uses living organisms or parts thereof to make or modify a product, improve plants or animals or develop microorganisms for specific uses. It is invaluable in research on conservation of bioresources. Although modern biotechnology is a newly introduced science (less than 50 years old) its impact has greatly excited the imagination and provoked the concern of almost every part of the society worldwide. Developments such as the tomato that can be frozen and other agricultural crops that have been genetically engineered for insect and virus resistance and which are in or near commercial release are simply spectacular by any standard. The richness of plant and animal diversity in Ukraine is a major asset in agricultural development and, therefore, the conservation of such resources is fundamental to the progress and usefulness of biotechnology.
