The greening of local environment
The solution of the problem of eco-sustainable development requires new approaches to conservation of the environment. The re-consideration of values and change in the orientation of global society in its relationship to nature, brought about by the cataclysms in the environment and its components, have been accompanied by the formation of new eco-policy system. Sustainable development links economic, environmental and social aspects of development in the true integrity. Aiming to do steps towards more green and sustainable future and taking into account poor state of European environment, it seems, one of the main next task is to prevent an increase of depletion of natural systems, as well as to establish favorable conditions for renaturalization and introduction the principles of eco-sustainability. One of the ways and mechanisms to achieve these purposes is ecological tourism - modern, synergetic and quick-developing sector of economic, social and environmental activity.
At present time about 16 mln people live at Ukrainian country-side. 2.7 mln of rural able-bodied people are employed at the individual subsidiary household, 730 000 of able-bodied people are not employed. So, the problem of rational use of the excess of country-side labors which increases from year to year is of a great importance. One of the way to solve this problem is organization of recreational servicing of population and regulated rest in villages. It will contribute to rising of rural employment and development of local economics. It also will draw attention to falling into decay villages having valuable nature or historical monuments and will contribute to its revival, it could be a good contribution to overcoming the crisis. Taking into consideration the realities of the modern complicated economical situation in Ukraine it should be noted that rural green tourism does not require large investment because it foresees using of existing potential of country regions: unique nature resources and objects of historical and cultural heritage, available housing fund, food produced at the individual subsidiary household. On the other hand green rural tourism stimulates rising of cultural-educational level of people, it also made them to keep the environment in a due state. The above mentioned is completely correspond to the concept of sustainable development which foresees a harmony between effective economy, nature conservation and strengthening of social guarantees for people.
Rural green tourism in Ukraine becomes more and more popular. More and more individual farms invite all of those who are tired from the noise of trams and vehicles, who does not want to breath polluted air and is exhausted from being in a crowd and wish to have nice rest in a lovely Ukrainian village. There is a good possibility to relax in it. “Village in Ukraine looks like a painted Easter egg. Green forests, blossoming gardens, white houses...” well-known Ukrainian poet Taras Shevchenko said. Green rural tourism to a great degree could facilitate the revival of Ukrainian village, consolidation of our state, strengthening of original national culture because just a village remains to be exponent of values which called national roots.
Taking into account that in the present condition of economy crisis economic and social problems of country-side have become uncommonly acute, the development and spreading of green and rural tourism in Ukraine is of a great value. Issues concerning the organizing and legal ensuring of relaxation in rural areas are constituent part of social policy of the state. Governmental support of small enterprises is being carrying out according to state and regional programs of supporting of a small enterprise. The development of the sphere of green rural tourism is also foreseen in these programs. In the European Union tourism directly employs more than 9 min people, representing 6 % of the total employment and 5,5% of GDP. There is a consensus that development should take place in a sustainable way in respect and in harmony with environmental historical and cultural heritage of a region. The further development in this respect can be based on econet concept and program.
Summary
Ukraine belongs to the countries with the high level of negative ecological consequences cause by economic activity. That is why the problem of environmental protection and the sustainable use of natural resources is of primary importance. High concentration of population, and industrial production and technologies make very bad influence on environment.
The loss of biodiversity, and especially of genetic and species diversity, represents a loss to all people, today and in the future. Moreover, the impacts of ecosystem and habitat degradation reach beyond national boundaries. Climate regimes, river flows and migratory species are all affected.
The interconnections in the world environment mean that biodiversity loss in one area is liable to be felt widely. The Convention on Biological Diversity is a key element of the national and international framework for biodiversity conservation. A number of other legal instruments are also important. Current agreements cover a range of specific conservation issues, and should be reviewed and strengthened. In addition, proposed conventions or agreements on global warming and forests must also be crafted to support biodiversity conservation. Strengthen the effectiveness of existing international conventions and treaties covering the conservation of ecosystems, species and genes. Ensure that international agreements on climate change and forests are compatible with the Convention on Biological Diversity and that they support biodiversity conservation.
As evident from the previous experience, it could be quite difficult to implement the sustainable development policy even under the favorable conditions of a prosperous economy. Thus it is even more difficult to pursue this goal in Ukraine, since this country is now undergoing dramatic changes, trying to overcome a profound crisis and to solve numerous particular problems.
As sum-up, the main goals in this respect are:
conservation, improvement of the environment and restoration of nature and disturbed ecosystems, landscape components and habitats of some species;
promoting sustainable, well-balanced use of natural resources;
minimizing any indirect negative influences on ecosystems, their components and ecological complexes;
strengthening public awareness, improving availability of information on biodiversity, involving more of local population in conservation activities;
defining and strengthening responsibility for biodiversity conservation, especially the responsibilities of institutions, organizations, land users, companies and individuals that use or affect natural resources.
For achieving the above goals, it will be necessary to implement and develop adequate legal, financial, organizational, scientific, educational and informational measures. Thus, the major aspects of biodiversity conservation activities are:
conservation and restoration of coastal, lacustrime, steppe, maritime, riparian, floodplain, mire, wetland, meadow, forest and mountain ecosystems;
preservation of species and populations;
ecological optimization of urban landscapes and other highly disturbed territories;
“ecologization” of agricultural landscapes and agricultural technologies, as well as existing practices in forestry, fishery, game, land and water management;
development of the national ecological network (a system of “green corridors”) as a component of the EECONET.
The realization of the above measures will give an opportunity to stop negative changes of the living component of the environment and facilitate the implementation of the principles of sustainable development and balanced use of natural resources.
In the countries in transition (including Ukraine) a problem is that the requirements of environmentalists of transition to sustainable development supposedly contradict striving of the majority of the population to have cheap goods and services. But just these countries have a good chance to restructurize and renew their obsolete economies with the orientation to sustainability. Just sustainable production must result in increase of employment.
