THE ENGINEER'S ROLE IN WATER RESOURCES PLANNING1

Engineers have traditionally led the planning effort in water resources developments. The engineer's leadership role in water resources, as well as in many other planning activities, has been challenged by technical and scientific people as well as by the general public for insensitivity to social, aesthetic, ecological, and political problems created by planning. The paper draws attention to the fact that the engineer cannot continue to expect the role of leadership to fall to him unless he prepares himself properly for that role. However, it is brought out that the engineer, by his education and training, is still the best qualified among all the representatives of the various disciplines associated with water resources planning to lead the planning effort if he prepares himself for the task. The requirements for preparation for leading water resources planning are outlined.     

PROJECT 2000, A PLANNING IMPERATIVE1

Time is running out on this country's planners. Generally speaking, the art of planning has retrogressed since the time of Christ. If we are to survive, this will have to be drastically changed by the year 2000. To achieve this, we need to begin to change our thinking, today. We badly need wider social planning, giving us more alternatives-more thought on where we are going. Reasonableness requires blending of planning and construction-but a sharp line of independence is essential. We must think about all the consequences of a particular act. Through intensive professional development and achievement of professional expertise, many outstanding technicians often move into vital decision making positions within their respective agencies. As planners, they see a part of the action but miss the big picture. Problem solutions become restricted to agency or individual authorities and are not always the best alternative. Thus, the planning field is overflowing with solutions to our every problem but many solutions offer spot control, and while the black spot is removed from the garment the white spot remaining from the solution offers little consolation to the wearer.     

Global-scale vs. regional-scale scenario assumptions: implications for estimating future water withdrawals in the Elbe River basin

In this paper, we explore how scenarios of future water withdrawals in a river basin are influenced by scale-dependent quantifications of the driving forces for two global-scale storylines. Either global-scale information or region-specific information is used to do the quantifications. In addition, we analyze the impact of including or not some restricted regional-scale information in the employed water use model. To develop scenarios of water withdrawals in the German part of the Elbe River basin, we applied the modules for domestic, thermoelectric power and manufacturing water use of the global water model WaterGAP, using scale-dependent driving forces scenarios and other scale-dependent model input. In the global-scale quantitative interpretations of the storylines of the IPCC SRES scenarios A1 and B2, all major driving forces of water withdrawals in the basin—population, thermoelectric power production and industrial gross domestic product—show vigorous increases between 2000 and 2025, while from the regional perspective, smaller increases but mostly decreases appear to be plausible. These discrepancies are partly due to the fact that for the global-scale interpretations only the historic developments until 1990 were taken into account, and not until 2000 as in the regional case. The resulting scenarios of sectoral water withdrawals in 2025 differ strongly between the two scale-dependent interpretations of the storylines, with the global one leading to much higher absolute water withdrawals and much lower withdrawal decreases between 2000 and 2025. Therefore, for regional assessments of water withdrawals, we recommend to embed the scenario analysis in global-scale storylines by performing regional-scale quantifications of the global qualitative driving forces scenarios, based on a limited amount of region-specific information.     

Housing reconstruction after two major earthquakes: the 1994 Northridge earthquake in the United States and the 1999 Chi-Chi earthquake in Taiwan

The idea of pre-impact recovery planning has recently been promoted by researchers and practitioners, but very little research has been done to evaluate its effects on disaster recovery. This study compared two jurisdictions — the city of Los Angeles, California and Taichung county in Taiwan — in their recovery from earthquakes. Although the two cases also differ with respect to variables other than the presence of pre-impact recovery plans, the available data suggest that having a pre-impact recovery plan facilitates housing reconstruction and allows local officials to make more effective use of the window of opportunity after disaster to integrate hazard mitigation into the recovery process.     

Effects of social interaction between Afghan refugees and Iranians on reproductive health attitudes

Afghan refugees in Iran, like many Muslims around the world, think that using contraceptives is against their religious beliefs. The majority of Iranians also thought so until a decade ago. Since then an all-encompassing social movement has emerged in Iran in which women and young people have played decisive roles. This movement has led to an attitude shift towards acceptance of family planning across Iranian society. High-ranking clerics, responding to the social movement, issued progressive edicts indicating that poor families could practise family planning. This paper reports the findings of focus group studies carried out among Afghan refugee men in two communities in Iran. The findings indicate that exposure to Iranian life, especially the rulings of Iranian clerics, have influenced Afghans' views on family planning. The findings also indicate that a system of justification is needed to help people avoid both social sanctions and individual stresses resulting from a controversial practice regarded as a sin for centuries.     

The Area Production Model: a tool and concept for sustainable land-use and forest-resource management

In developing countries, planning in the forestry sector has been seen as an appropriate instrument to prepare and implement government policies and programs. Despite its potential and recent advancements in, for example, remote sensing and infrastructure, tropical forest land-use planning is often formal and non-integrated with agriculture. It rarely involves all legitimate stakeholders and neglects taking into account actual land-use. The socio-economic and environmental consequences of these shortcomings emphasise the need for alternative ways of approaching planning. This article summarises the idea, structure and current status of the Area Production Model (APM), originally developed in the 1980s, which is now gaining interest as a land-use planning tool in Africa and Asia. It describes the development over time of production and consumption in agriculture and forestry within a defined geographical area operating under different assumptions on management, land use and socio-economic and macro-economic changes. From a narrow perspective, the APM is a fairly simple computerised tool for generating scenarios. In a broad sense, it is a concept comprising the whole planning process including organisation, inventory, data analysis, consensus building and strategy. A case-study in Laos, based on verified data for a historical period of 45 years, and a review of different APM applications in the world over the last 15 years are presented as a base for conclusions about its potential and shortcomings. In some cases where the APM concept was used in training courses and planning exercises involving stakeholders, it generated a strong interest in collecting and analysing relevant information. It provides the means of addressing a number of shortcomings in current planning.     

Conflict and engagement: An empirical study of a farmer-extension partnership in a sustainable agriculture program

Stakeholder engagement is a crucial concept of extension education. Engagement expresses democratic values of the land-grant mission by providing opportunities for stakeholders to influence program planning, including setting the agenda and negotiating resource allocations. In practice, the concept of engagement guides the formation of partnerships among extension, communities, industry, and government. In the area of sustainable agriculture, however, stakeholders may conflict, presenting challenges to the engagement process. Results from a study of a Canadian sustainable agriculture program, produced using cultural anthropology and participatory action research, detail challenges of the engagement process that led to reconstruction of a farmer-extension partnership. Notable in the early phase of the reconstruction process were critical reflection, stakeholder forums, exclusion through caucusing, and coalition building. An argument for a neopragmatist view provides a theoretical basis for understanding counterintuitive dimensions of engagement revealed by the study.     

MANAGING TAIWAN'S RESERVOIR WATERSHEDS BY THE ZONING APPROACH1

ABSTRACT: For many years, a commonly used strategy for source water protection in Taiwan has been setting up arbitrary, fixed‐width buffer zones near sensitive waters, such as water‐supply reservoirs, and prohibiting any development in their watersheds. However, such regulations are now often viewed as infringing by the government on landowners' property rights, a situation that has led to citizen protests. This paper describes a proposed strategy that is water‐quality based and uses a quantitative zoning approach. A reservoir's watershed is divided into several zones beginning from the normal water line to the divide. Different levels of best management practices (BMPs) are required for controlling runoff pollution in different zones. The layout of the management zones is based on a number of factors such as reservoir classification, water quality conditions, and physical characteristics of the watershed. The goal of promoting such an approach is to try to balance the needs of watershed development and water quality protection. A case study using the Tapu Reservoir Watershed in Northern Taiwan as an example for illustrating the proposed zoning approach is presented.     

Corporate strategy and viable future land use: planning for closure from the outset of mining

This paper provides an overview of the environmental impact of mining on viable future land use and underlines the imperative of improved environmental management and closure planning. It argues that pollution prevention, through planning for closure, can lead to cost-effective strategies for sustainable minerals development and viable future land use. This seems to be most true for greenfield sites since, generally, the earlier closure planning and pollution prevention is built into a project, the more cost-effective and environmentally benign closure will be. Further, for greenfield sites, pollution prevention techniques can be employed from the outset, at the stages of exploration and mine development, and then monitored and improved through the operation stage to closure, and can be kept in place to manage future land use.
The paper discusses how global changes in the industry, following the liberalisation of investment regimes, and mergers and strategic alliances between key firms, has, by virtue of the diffusion of new technology, led to further opportunities to prevent pollution and optimise future land use through planning for closure from the outset. The objectives and components of closure plans are also reviewed as the paper draws on case studies to highlight some of the possible constraints and challenges to pollution prevention that may be faced at the level of both public policy and corporate strategy. The article concludes by suggesting a forward-looking approach to integrated environmental management and viable future land-use planning based on a dynamic model for environmental management.     

TIM: Assessing the sustainability of agricultural land management

TIM (Threat Identification Model) is a framework for the ex ante assessment of agricultural land management sustainability at the land unit scale that identifies sources of unsustainability within agricultural land management systems. The model explicitly links defined hazards to land productivity and environmental integrity, land resource data and information, and land management practice options using expert and local knowledge on land management and its potential effects. The model was tested in the Crystal Creek Subcatchment, a narrow coastal strip of land situated in north Queensland, Australia. This area was chosen due to the expansion of the sugar industry onto increasingly marginal land in the area, which represents a threat to sustainable land use and a requirement for careful land-use planning and land management.TIM may be used in a relational database as a stand alone decision support system for land-management planning. Its usefulness in land-use planning is greatest when it is linked to a Geographic Information System (GIS) as shown in this paper. GIS allows TIM outputs, such as constraints to agriculture and site-specific best-management practices, to be identified in a spatially explicit manner.The main advantages of TIM are that it can be done ex ante, it removes the need to define sustainability assessment criteria and indicators, it utilises current understanding of the causes and effects of land degradation and how different land-management practices influence these, and links this knowledge to definite land-management options.
