Nutrients are a limited resource and call for management. A sustainable nutrient management strategy reintegrates nutrients in the environment without accumulating harmful substances above an acceptable level. In this study a methodology to assess the environmental compatibility was developed. For this assessment both the (i) enrichment of pollutants in the soils and (ii) the area specific nutrient demand of the crops were taken into account. The method considers, that products applied on soils also contain stable substances, and as a consequence the accumulation of pollutants diminishes. Additionally, it is considered, that increasing substance concentrations in the soil will lead to an increase of substance flows out of the soil by percolation, plant-removal (and erosion). In practice long term management strategies are restricted by the time span considered, the accepted accumulation of substances, the plants real needs and legal constraints. The rating of various goods can be made with the ratio of the added nutrients, considering the pollution criteria, the legal constraints and the plants real needs.

Trends over the past 25 years indicate that Argentina’s growth in its grain crop productivity has largely been supported by the depletion of the extensive fertility of its Pampean soils. Long-term research provides insight into sustainable nutrient management strategies ready for wide-scale adoption.

Advice on enuresis has been provided by a range of individuals. Many myths and misunderstandings have been responsible for the confusing range of opinions given to those who seek help. Management should be based on an understanding of the physiology of the condition and the established facts about its treatment. There is still a lack of awareness about how effective are the management strategies now proposed by those who base their practise on the extensive research that is now documented. The best results are obtained with conditioning therapy, when this is supervised and supported. There is an important role for 'wetness' alarms in conditioning. There are now body-worn mini-alarms, established by over a decade of use, that are inexpensive and reliable. There is a decreasing role for tricyclic medication. The recently introduced pharmaceutical Minirin (desmopressin) is useful in short-term management to get dryness on social occasions and, in selected individuals, might have a role in long-term control of enuresis, when conditioning has not been effective. There is an important need to provide advice and treatment facilities for all those with enuresis - a treatable condition.

Island floras have been subject to catastrophic changes since human colonization; the Hawaiian Islands exemplify this pattern of species decline and ecological change. Archaeological and historic findings support the former existence of coastal, lowland and interior Pritchardia dominated forests. Wild Pritchardia populations are highly fragmented and exhibit poor or absent regeneration in the wild. This study records seed predation, goat grazing, pig damage, and human harvesting on six wild populations of three species and outlines requirements for the long-term management of wild populations. Only one population of the six studied was found to contain seedlings. Recommended conservation management strategies are outlined.

The Way

Overweight and obesity are known risk factors for the development of lymphoedema, and are also well-recognised factors complicating the management of lymphoedema. However, a degree of uncertainty remains regarding the way in which obesity impacts upon the condition, and there is little detail about the practical application of weight management strategies in the population with lymphoedema. This article provides the background for ongoing research into the association between lymphoedema management and obesity. It is hoped that this research will provide important insights into the long-term management of lymphoedema.

Selection Of

About 15% of the area of the Czech Republic is classified as territories with special status of protection, most of which is covered with forests. At present, at the time of integration of the country into the European structures, an increase in the area of such territories by approximately 20% is expected. The territories show significant variation of protection objectives, management restrictions, profound differentiation in natural conditions, structure of ownership and different levels of damage, especially that caused by anthropogenic pressure. This situation requires the formulation of long-term management strategies. The problem can be solved in the following successive steps: formulation of variants and alternatives of management strategies based on a retrospective analysis of forest development; prognosis of the forest condition development after application of the individual management strategies on the basis of growth and development simulations; addition of technological and economical bases; selection of optimal variants and alternatives from the viewpoint of the fulfilment of the owner’s management goals, in accordance with the principles of forest policy and from the viewpoint of the fulfilment of the protection objective formulated for a specific territory with special status of protection. A set of methods for following the above-mentioned steps is specified in the presented contribution.
