Answer:In the past, national and international development agencies have seldom relied on—or called for—basic information on biological diversity. This can no longer be the case. Many development projects include a significant natural resource component and thus require sober analysis of their environmental impacts. More broadly, international agencies and resource and planning ministries in developing countries need information about biological diversity to formulate development plans and specific projects that are both successful and sustainable.
Pertinent information on biological diversity in most developing countries is too sparse or scattered to be of practical use. Often it is unavailable altogether. A good deal of "gray" literature exists—unpublished reports, files in government archives, studies of limited distribution. The most important of these should be analyzed and made more accessible. In general, however, the required information can be gathered and disseminated only through systematic efforts to strengthen the entire research process.
Development agencies need to know which kinds of research are of greatest relevance as they assist client governments and develop the rationale to secure funding for this research. A large and growing body of literature describes conservation strategies appropriate to different species, ecosystems, and regions in developing countries. This includes journals such as Biotropica, Biological Conservation , and Conservation Biology. Recent agendas, involving a range of basic and applied research needs, can be found in Research Priorities in Conservation Biology (Soulé and Kohm, 1989); From Genes to Ecosystems: A Research Agenda For Biodiversity (Solbrig, 1991); and The Sustainable Biosphere Initiative: An Ecological Research Agenda (ESA, 1991). Subsequent chapters of this report focus on the socioeconomic and cultural aspects of biodiversity research in developing countries. This chapter provides an agenda for biological research that must be undertaken to provide a sound foundation for these human dimensions of successful conservation.
The state of knowledge of biological diversity, described in the previous chapter, suggests that the most basic research requirement is to gain a more complete sense of "what's out there." The committee that produced the 1980 National Academy of Sciences report Research Priorities in Tropical Biology recognized this fundamental need and called for a "greatly accelerated ... international effort in completing an inventory of tropical organisms" (NAS, 1980). Although these efforts have accelerated to a degree, the task has become far more urgent, complex, and challenging in the interim.
Effective conservation of biological diversity requires more than just basic knowledge of its components. We need to know as well the distribution of biological diversity and those areas where it is most concentrated. We need to know the potential benefits that organisms can offer to humanity and, at least in a general way, how they and the biotic communities they form are faring. We need to understand better the ecological dynamics of the systems in which organisms exist, the temporal and spatial patterns that govern their fate, and the best means to conserve both organisms and habitats over the long run. We need to develop methods to use biological resources without depleting them or undermining the human communities with which they coexist. Finally, we need to learn better how to restore those lands and waters that have been degraded by unwise development.
Explanation:
Answer:
migratory
Explanation:
The pattern of migratory distribution of species may require collaboration between different countries for effective preservation. This is because species migration can make them enter different territories, which will need to provide an effective level of preservation for species survival.
Migration is the group displacement of many mammals, birds, fish, insects and other animals. This movement happens at certain times of the year and is part of the life cycle of these species. Animals know no boundaries between countries and can therefore migrate to many different territories, forcing governments to maintain efficient levels of preservation so that species can survive.
