People from different professional backgrounds tend to view management differently. To the ecologist, water resources management water resources is often connected with reversing the effects of the deterioration of ecosystems, land degradation, pollution and destruction of wetlands. To the water engineer, water resources management is about dams, reservoirs, flood protection, diversions, river training, water treatment and reclamation. To the lawyer, the main issues in water resources management are the ownership of water, systems of water rights, the priority of use, water markets, water legislation, and international water law. To the economist, water resources management is connected with economic efficiency, cost recovery and the attainment of national objectives. It can be truly said that the Water Resources Management, in all its components, is a multi-disciplinary field. In recent years, a number of concepts related to water resources are widely used, such as Water Resources Development, Water Recourses Planning, Water Recourses Management, and more recently, Integrated Water Resources Management. It is useful to define these terms, or at least agree on some broad definitions so that those involved in this work have a common understanding of their meaning. Water Resources Development: actions, mostly physical, that lead to the beneficial use of water resources for single or multiple purposes. Water Resources Planning: planning of the development, conservation and allocation of a scarce resource (sectoral and intersectoral), matching water availability and demand, taking into account the full set of national objectives and constraints and the interests of stakeholders. Water Resources Management: the whole set of technical, institutional, managerial and operational activities required to plan, operate and manage water resources. In other words, Water Resources Management can be considered as a process, including all activities on planning, design, construction and operation of water resources systems. In recent years, definition of the integrated water resources management has been used. Integrated Water Resources Management takes accounts of: I. all natural aspects of the water resources; 2. all sectoral interests and stakeholders; 3. the spatial variation of resources and demands; 4. relevant policy frameworks (national objectives and constraints); and 5. institutional levels. Why Integrated Water Resources Management? In order to have effective water resources management, the following principles are required: • National water resources management should be undertaken in a holistic, determined and sustained manner to meet national development goals and protect the environment. • Management of specific water resources should be decentralized to an appropriate level responding to basin boundaries. • Delivery of specific accountable public, water services should be delegated private or co-operative services in a defined geographical agencies to autonomous providing area to their customers, measured and water and/or members, for appropriate fee. • Water use in society should be sustainable - with incentives, regulatory controls and public education promoting economic efficiency, conservation of water resources and protection of the environment - with a transparent policy framework: • ~hared water resources within and between nations should be allocated efficiently for the mutual benefit of all riparian users. The integrated water resources management will be an effective tool to implement the above principles. A. GRAMMAR REVIEW BE + P/I (past participle) I. Passive voice: - In the present simple: am/ware + PIl E.g: Water resources management is defined differently. - In the present perfect: havel1las + been + PIl E.g: A lot of hydroelectric power plants have been built in Vietnam. - With modal verbs can/should: can/should + be + PIl E.g: + Shared water resources should be allocated efficiently for the mutual benefit of all riparian users. + Water resources management can be viewed differently. II. Infinitives - Infinitives are used to express purpose. They answer the question why . ? E.g: A number of hydroelectric power plants have been built to meet the energy demand. - Infinitives are used after certain adjectives. E.g: It is useful to define the terms related to water resources management. III. Words of purposes: for, to, in order to, so that for + N to + V in order to + clause so that E.g: They wentfor a walk. We come here to learn English. We must eat in order to live. They went early so that they could get good seats. B. COMPREHENSION CHECK I. Answer the following questions I. What is the view of ecologists on water resources management (WRM)? 2. What is the view of water engineers on WRM? 3. What are the concepts related to water resources? 4. What these terms mean? Match the term with its definition. Terms Definition I. Water Resources Development a. a process involving all activities of planning, designing, constructing and operating water resources systems 2. Water Resources Planning b. actions resulting in beneficial use of water resources for one or more purposes 3. Water Resources Management c. plans to develop, conserve and allocate a scarce resource; to match availability and demand; to consider all the national objectives and constraints and the interests of stakeholders What are the contents of the integrated WRM? 6. How many principles are required to have effective WRM? II. True, false. Correct the false ones. I. People from different professional backgrounds have the same view on WRM. 2. To the water engineer, WRM is about dams, reservoirs, flood protection, diversions, river training, water treatment and reclamation. 3. Water Resources Development: actions that result in the beneficial use of water resources for only one purpose. 4. It is said that WRM involves planning, design, construction, operation of water resources systems. 5. The government should decentralize management appropriate level responding to basin boundaries. of specific water resources 6. In order to meet national development goals and protect the environment, undertake water resources management determinedly and sustainably, holistically. C. PRACTICE I.
