The role a botanical institute can play in the conservation of the terrestrial biodiversity in a developing country

The need to integratein situ conservation into the planning process is outlined, and the importance of vegetation survey to determine conservation priorities and to identify areas suitable forin situ conservation is stressed. A case is presented, drawing on experience gained in Zimbabwe, of how a botanical institute can become an integral part of biological conservation. The institute should consist of a herbarium, a botanical garden, a gene bank and a vegetation survey unit. The function of each section, how they interlink, and how they can be integrated are discussed.     

Biomechanical rationale of coronary artery bypass grafting of multivessel disease

The biomechanical model of human coronary arteries was modified for improving the quality of diagnosis and surgical treatment for coronary heart disease. The problem of hemodynamics in the left coronary artery with multivessel bed disease – 45% stenosis of the anterior descending branch and 75% stenosis of the circumflex branch – was particularly considered. Numerical simulation of the coronary arterial bypass of the main trunk was carried out to estimate the functional condition of the coronary arteries after restoring myocardial blood supply by surgery.     

Integrated planning and management of freshwater habitats,including wetlands

Freshwater habitats play a very important role in sustaining human activities. Natural functions of wetlands, and other freshwater habitats, generate a wide array of resources that directly or indirectly support the economic and social welfare of diverse groups of people. This role is being seriously weakened as a result of inappropriate planning and management approaches which fail to maintain the functional integrity of the freshwater ecosystems with the result that the flow and quality of resources is degraded. This paper illustrates some of the major functions of wetlands and presents a case for developing integrated planning and management practices that protect the health and productivity of freshwater wetlands and seek to optimise the sustainable use of the flows of resources they generate.     

Planning oral health care for the elderly in Israel for the years 2000 and 2025

The methodology and conclusions of this workshop arc reported here because the problems requiring solution are not unique to Israel. They will increasingly have wide geographical and political application. The population of Israel since its establishment in 1948 has increased about sixfold. The numbers of the elderly (65+) have increased about tenfold. The current situation must be examined and estimates obtained for the next ten years. Only thus can the system be enabled to cope with the problem as it develops. The chosen method was a carefully preplanned, multisectorial workshop. Recommendations were discussed, amended and finalised. The recommendations of the workshop included: Baseline national data is urgently required. Guidelines are required for selecting specific target populations to which priority should be given. The current favourable situation of adequate oral health manpower in Israel makes it possible to encourage providers of oral health care towards treatment for the elderly. It is essential that the appropriate health authorities allocate sufficient funds for the following urgent purposes: the conduct of a national survey of the elderly population; the establishment of oral health units on a trial basis in some selected hospitals; support institutions of higher education to facilitate training in geriatric dentistry. Conclusions. The workshop was multidisciplinary because it was necessary to include all the expertise and experience available as vital elements of the policy making process. This type of workshop was found to be an effective tool for planning oral health services.     

Identifying Mozambique's most critical areas for plant conservation: An evaluation of protected areas and Important Plant Areas

Successful protected area networks must represent biodiversity across taxonomic groups. However, too often plant species are overlooked in conservation planning, and the resulting protected areas may, as a result, fail to encompass the most important sites for plant diversity. The Mozambique Tropical Important Plant Areas project sought to promote the conservation of Mozambique's flora through the identification of Important Plant Areas (IPAs). Here, we use the Weighted Endemism including Global Endangerment (WEGE) index to identify the richest areas for rare and endemic plants in Mozambique and subsequently evaluate how well represented these hotspots are within the current protected area and IPA networks. We also examine the congruence between IPA and protected areas to identify opportunities for strengthening the conservation of plants in Mozambique. We found that high WEGE scores, representing areas rich in endemic/near-endemic and threatened species, predict the presence of IPAs in Mozambique, but do not predict the presence of protected areas. We also find that there is limited overlap between IPAs and protected areas in Mozambique. We demonstrate how IPAs could be an important tool for ensuring priority sites for plant diversity are included within protected area network expansions, particularly following the adoption of the “30 by 30” target agreed within the post-2020 Convention on Biological Diversity framework, with great potential for this method to be replicated elsewhere in the global tropics.     

Irrigation planning to transform subsistence agriculture: Lessons From El Salvador

Experience with irrigation schemes designed to improve the productivity of subsistence farmers in Latin America seems to parallel the results of the green revolution in Southeast Asia. Although in some cases the impact on the productivity has been significant, in far too many cases the pervasive pattern of inequity has been reinforced. This case study of the Irrigation District of Zapotitan in El Salvador analyses some of the reasons for the unexpected results, with particular reference to the planning process. It essentially illustrates that the transformation of subsistence agriculture through irrigation demands new institutions designed not only to service agricultural production but also to ensure the accrual of benefits on the targeted group.     

Toward the brave new zoo: Species program planning for reproductive technology development

This article outlines some of the advantages inherent in domestic animal reproductive technology development and compares them to the disadvantages in such development in wildlife species. Species program planning (as proposed by the American Association of Zoological Parks and Aquariums' Species Survival Plan) is offered as an important first step in organizing appropriate research toward reproductive technology development in wildlife species.
