Extractions: A LEGAL AND INSTITUTIONAL FRAMEWORK FOR THE ANALYSIS OF WATER AND LAND MANAGEMENT: A METHODOLOGICAL TOOL FOR RIVER BASIN MANAGEMENT Dr Ian Hannam Member, IUCN Commission on Environmental Law; Center for Natural Resources, Department of Infrastructure, Planning and Natural Resources NSW Australia ABSTRACT Achieving and maintaining sustainable use of water and land resources is a major challenge for the world in the 21 st A legal and institutional framework for water and land management was prepared as a means of gaining information on the pattern and capacity of the legal and institutional system in the PRC to accomplish water and land management (Hannam 2002a,c). The framework, which is applicable at the river basin level, can be used to identify gaps, strengths and weaknesses in an existing legal and institutional system. It is also a means to identify possible solutions to these problems and areas where the existing system might be improved to better manage water and land resources. Introduction A legal and institutional framework for water and land management was prepared as a means of gaining information on the pattern and capacity of the legal and institutional system in the PRC to accomplish water and land management. The framework is applicable at the river basin level where it can be used to identify gaps, strengths and weaknesses in the existing legal and institutional system for water and land management. It is also a means to identify possible solutions to these problems and areas where the existing legal and institutional system can be improved to better manage water and land resources (Hannam 2002 a, b, c).

Wiley, New York. METHODOLOGY RESULTS AND DISCUSSION FUTURE PROSPECTS REFERENCES ... Table 1 Guayule ( Parthenium argentatum Gray) is a promising alternative to rubber tree ( Hevea brasiliensis Muel. Arg.) for production of natural rubber in semiarid regions of the world. For the United States, which is totally dependent on foreign sources of natural rubber, developing guayule as a commercial crop should be a high priority. A domestic source of natural rubber is vital to our national defense and helps balance the budget by reducing the one billion dollars spent annually for the imports of Hevea rubber from southeast Asia. Salt-tolerant guayule cultivars are needed for economic production of rubber on marginal lands and in areas with low quality saline water. The available guayule germplasm which is being used to develop new guayule cultivars are 2 n = 36, 54, or 72 (Bergner 1944, 1946; Stebbins and Kodani 1944). Plants with 2

Mango Tree Management Systems - III easy tree manipulation for inducing water stress required top 6 10 inch of soildepth and tree manipulation therefore become easy with controlled irrigation. http://members.tripod.com/Shanthap/mb3.htm
Extractions: Management of Bearing Trees Management system adopted for bearing trees are quite different, especially with regard to nutrient and irrigation management, than that adopted for non bearing trees. The shift in management system could be commenced 3-4 years after planting dependin g on the tree size. The objective in managing bearing trees is to promote the tree reserve level for subsequent flowering and fruiting while at the same time trees are allowed to grow and maintain sufficient vigor for producing high yields in following years. Tree reserve levels could be increased by two ways. That is by optimizing conditions required for high rate of photosynthesis and by controlling excessive vegetative growth that consume stored reserves unnecessarily. Photosynthesis rate and excessive vegetative growth may be manipulated by controlled N and water supply that will be discussed under nutrient and irrigation management later. In bearing tree management the growers has to think the productivity of trees in long run to maintain the sustainability of tree production capacity. A sustainable production may be achieved only if trees are managed with a scientific tree management system based on the phenology or growth cycle of bearing trees.

Use Of Reclaimed Water And Sludge In Food Crop Production and on the sustainability of soils for crop Where alternative irrigation water ischeaply available, there are of incentives to apply reclaimed water or sludge http://books.nap.edu/html/sludge/summary.html
Extractions: BACKGROUND Standards for the Use or Disposal of Sewage Sludge (Code of Federal Regulations Title 40, Parts 257, 403, and 503, and hereafter referred to as the "Part 503 Sludge Rule"). This rule builds on a number of federal and state regulations that aim to reduce pollutants entering the municipal waste stream thr ough source controls and industrial pretreatment programs that have reduced the levels of contaminants in the sludge as well as in the final effluent. The Part 503 Sludge Rule defines acceptable management practices and provides specific numerical limits for selected chemical pollutants and pathogens applicable to land application of sewage sludge. In this context, sewage sludge-traditionally regarded by many groups as an urban waste requiring careful disposal-is now viewed by the wastewater treatment i ndustry, the regulatory agencies, and participating farmers as a beneficial soil amendment. CONCLUSIONS AND RECOMMENDATIONS Adequacy of Existing Regulations for Pathogens in Reclaimed Water and Sludge Guidelines for Water Reuse . There are currently 19 states that regulate the practice by setting criteria for reclaimed effluent quality, such as microbiological limits or process standards; crop restrictions; or by waiting periods for human or grazing animal access or before crop harvest. State regulations vary; some require very high-quality effluents to reduce the concentration of pathogens to levels acceptable for human contact prior to irriga-tion. Others depend on the use of crop restrictions and site limitations, thus allowing required time for pathogens to decrease to acceptable levels. In general, modern wastewater treatment procedures incorporate monitoring and technical redundancies that provide system reliability and protection against exposure to pathogens.

Extractions: Irrigation scheduling Economics of irrigation management Historically, irrigation water has been a rather inexpensive and unlimited commodity to farmers; gradually, it is becoming ever more costly and limited. Cases of a cost exceeding 0.3 euro/m for pressurized water are not uncommon in the Mediterranean area as severe limitations in supplies become more and more frequent Mjelde et al. (1987) maintained that the development of irrigation strategies lags behind technological developments, however several important conceptual tools are available to decision-makers, derived from economic theory and decision-making supports. The economic theory elaborated the principles illustrated in the figure below, where: P unit output price C unit cost of water Y output W water volume P profit with the following assumptions: Y = f (W) P = P x Y - C x W = P x f (W) - C x W The condition for total output maximization is that the first derivative of f (W), namely f'(W) be equal to . For profit maximization the condition is Pf ' (W) - C = then Pf ' (W) = C and f 'W = C / P The curve Y = f (W), when plotted against the C/P line is useful in giving indications on profit and water efficiency maximisation; the points X

Extractions: Misunderstandings pertaining to terminology of drought and water usage issues have been evident in newspaper, magazine articles,and television news sections. These definitions must be clarified before substantive discussion and research can be properly dissected. Evapotranspiration (ET) is defined as the total amount of water a plant transpires (loses from evaporation or transpiration through leafy tissue or other means) and the water that evaporates from related soil areas. This sum is measured in experiment evaluations. Water use rate Drought resistance and drought tolerance are general terms used to describe a wide range of water usage issues. Because these terms often do not mean the same thing to different people, it seems necessary to specifically define four separate terms that can be used to describe the effects of drought for a meaningful analysis: Dehydration tolerance - the ability to withstand water deficits in tissue caused by insufficient water quantity which may slightly but not significantly affect turf quality. This definition refers to the characteristic of a grass to thrive during a given timeframe of "low" or minimal water in the leaf tissue. An example would be Bahia, Buffalo, and specific cultivars of St. Augustine grass which can thrive with minimal water content available in their respective blades. The term drought tolerance is often used.
