Operational Data

Initiated by a case study to assess the effectiveness of the modernisation actions undertaken in a water supply system, some R&D activities were conducted to construct a global predictive model, based on the available operational failure and recovery data. The available operational data, regarding the water supply system, are the pipes’ diameter, failure modes, materials, functional conditions, seasonality, and the number of failures and time-to-recover intervals. The operational data are provided by the water company responsible of the supply system. A predictive global model is proposed based on the output of the operational data statistical assessment. It should assess the expected effectiveness of decisions taken in support of the modernisation and the extension plan.

Study Results

In Mexico, water planning is based on the National Water Law, the core of which is Integrated Water Resources Management (IWRM). The municipality provides wastewater treatment and reuse, and an integrated approach is mandatory for these processes. However, a traditional (non-integrated) management regime has prevailed in water legislation, resulting in pollution and the inefficient use of water. The objectives of this research were to analyze the Mexican legal framework and international guidelines in the use of reclaimed water for agricultural irrigation and environmental discharges, and to evaluate challenges facing reclaimed water in the Maneadero Valley, Baja California, as a case study. Results show that wastewater reuse was implemented in the absence of integrative planning and assessment of the potential impacts on the environment and public health. In addition, gaps between decisions linked to the legal attributes of the relevant institutions were identified. Defined roles across the three levels of authority, transparent and congruent funding, coherent water-quality requirements and the strengthening of stakeholder participation are needed to adopt integrated water resource management for reclaimed water use. The alignment of common goals on public health, environmental protection and agricultural development between authorities and the different sectors is crucial to bridge these challenges.

Energy Entropy

The article discusses the relevance of the problem of energy efficiency of industrial enterprises, along with increasing environmental safety of production and increasing social responsibility. The technique of estimation of production efficiency and its influence in management of ecological system on the basis of energy-entropy method is considered. Relevant questions are: improvement of the universal principles of energy efficiency in specific sectors and to develop tools of economic analysis energy infrastructure of industrial enterprises on the basis of the energy-entropy method using various ratios and find new ways of efficient use of energy. The purpose of this article is to develop new methods for assessing the efficiency of production and management. The problem is largely actualized by the fact that at present the question of assessing the effectiveness of energy systems management.

This paper uses Singapore as a case study to illustrate how staffing policies and practices affect the quality of the workforce which ultimately influence performance at employee and organization level. It reveals that Singapore public service has been able to put in place most of the ‘critical factors’ for an effective staffing system management. The presence of those critical factors have played an important role in making Singapore to be one of the most effective public services in the world. Finally, it forwards theoretical and practical implications of the study and future research direction.

Water functions are very diverse for humans for daily needs such as drinking water, bathing, agriculture, development, aesthetics, and lower temperatures. Palembang is a lowland area dominated by wetlands, tidal swamps, and rivers. The types of houses on stilts on the banks of the Musi river are limas, Gudang, and Chinese stilt houses which are always associated with the water environment. The construction of roads replacing the role of rivers has realized people that the water environment has an important meaning for the house on stilts. The research objective was to explore the meaning of the water environment from various aspects for residents, stilt houses, and their environment. This research method is a case study with data collection through interviews, observation, measurements, and taking photos. Data and findings were analyzed and juxtaposed with images in the field. The road construction has eliminated part of the function of the river and influenced the change in orientation of the house on stilts. In conclusion, respect for the water environment including rivers has decreased, causing the quality of the river to decline, and the house on stilts cannot take advantage of the existence of the water environment optimally

While the notion of social-ecological system resilience is widely accepted and applied, the issue of “resilience for whom” is clearly ignored. This phenomenon has also occurred in Taiwan. This article explores the roots of, and a possible solution to, this issue through a case study in the context of Taiwan’s indigenous peoples. The Danungdafu area, the focal social-ecological system, was studied. Qualitative research methods and an action-oriented research approach were employed. For a long period, the central government shaped the political, economic, social, institutional, and ecological contexts; dominated resilience discourses and determined the problem-framing and problem-solving agenda; defined the scale and levels at which social-ecological system governance issues were addressed; and determined the knowledge system used to define and solve problems. After 2011, a new participatory governance regime emerged. Multiple stakeholders, including indigenous communities, began to contribute to resilience discourses and influenced governance and trade-offs among differing governance goals. However, under the established structures dominated by Han people, indigenous views, rights, and well-being continue to be ignored. Affirmative action is required to recognize and safeguard indigenous rights. A practical institutional pathway is available to facilitate the transformation from “resilience for mainstream society” to “resilience for indigenous people” in indigenous territories.
