The purpose of this study is to analyze the impacts of different policies to address the water supply crisis experienced by the metropolitan region of Sao Paulo during 2013 to 2015 and evaluate the resilience of its water supply system for the coming years.

The methodology used in this study is based on the system dynamics simulation paradigm, combined with empirical data obtained from the regional water authority.

The results from the simulations suggest that the first layer of sustainability of the water supply in the region strongly depends on how the system’s operator responds to crises, in particular how it balances policies acting on the supply and demand for the resource.

Severe water crises typically make salient the perception that water is a finite and public resource. Long-term, sustainable management of the system requires a paradigm shift from widespread, old-fashioned beliefs that water is an infinite resource. It also requires active management to increase the system’s preparedness to withstand events caused by climate change.

This study contributes to the system dynamics and water resource management literature by presenting an integrative model to evaluate the resilience of a particular water supply system. Although there are previous studies on this subject, the present one focuses on the role that the water authority plays in a crisis and especially on a specific combination of policies to address an episode of crisis in a system unprepared for it.

Urmia lake water has impressively decreased recently and seriously endangered the lives of the inhabitants. In this paper, the effects of various factors on the reduction of the lake water are investigated and appropriate scenarios are proposed for future improvement. Due to the significant impact of agricultural issues on this crisis, this paper has focused specifically on agriculture. So, this paper aims to forecast and improve the lake water level.

In this paper, a system dynamics (SD) model, which is capable to consider various parameters and variables affecting the lake water level within nonlinear and dynamic relations, is developed.

To show the effectiveness of SD model, real data are used to run the model and the results show that the actual behavior of the lake water is reproduced with high validation (around 98.28 per cent). Also, five different scenarios are proposed to increase lake water volume. The hybrid Scenario 5 (which combines three other scenarios including increasing irrigation efficiency in the agricultural sector, changing cultivation pattern of agricultural products and returning some dams’ water that are consumed in the agricultural sector into the lake) is chosen as the most effective scenario for increasing lake volume about 15 billion m³.

The main contributions of this paper are systemic view to the whole problem, paying attention to the agriculture subject as one of the most important issues, considering many critical variables (e.g. evaporation, salinity and precipitation) and providing improvement policies along with assessing the effects of them.

The purpose of this paper is to evaluate the possibilities of continuous water supply in New Delhi, India and nearby places; also to scrutinize/assess/recognize the role of the Municipal Corporation and Delhi Jal Board (DJB), the departments which take care of water supply and demand in the region.

The paper takes the form of a case study and a literature review.

The authors infer that there is a bright possibility of continuous water supply in the region, provided there is improvement of water supply networks, auditing of supplied water, educating people for water conservation and rain water harvesting and proper distribution by building underground reservoirs (UGR) in different areas.

The conclusion and inferences of this research may enhance the existing literature on water supply, for the first time focusing on the Indian context, where there is no major problem in supply of water but the designed infrastructure creates shortages in the area.

This paper combines prospect theory (PT) and the technology acceptance model (TAM) proposing that technology anxiety (TA), risk averseness (RA), concern and resistance to use inhibit technology acceptance, while trust, social influence (SI) and compatibility are enablers to technology acceptance, particularly in the context of consumer adoption of retail technologies during crises.

A review of PT and TAM literature was conducted to develop a model which considers the impact of inhibitors and enablers on retail technology acceptance.

This investigation establishes a theoretical model of mid-crisis retail technology adoption behavior that can be tested quantitatively. Several propositions regarding relationships between proposed inhibitors, enablers and TAM are presented, as well as implications for future research.

This investigation further integrates PT and TAM, proposing that PT is an appropriate framework to investigate inhibitors and enablers of retail technology acceptance during crises.

Edible flowers have traditionally been consumed for their nutritional and medicinal properties. Aponogeton distachyos is an aquatic flowering plant native to the Western Cape of South Africa (SA) that used to be a wild plant gathered during the winter months, but it is now considered to be underutilised and endangered. This study aims at gaining insights from different stakeholders into the activities across the plant value chain and their impact on the consumption of Aponogeton distachyos.

The study methodology involved the identification of different stakeholders in the plant value chain and conducting qualitative in-depth interviews during the data collection. Twelve study participants were selected via purposive sampling and interviewed using semi-structured interviews (face-to-face, telephone and online).

Nostalgic connection of the flower with local culture and heritage and its unique taste and flavour are key consumption drivers. Promotional and educational efforts by food advocates and at public events help raise consumer awareness, which is generally lacking. Limited geographic and seasonal availability, perishability, price and quality issues emerged, together with low awareness, as main barriers to more frequent and geographically spread consumption.

Although wild edible flowers have been consumed for centuries, there has been little attention to their nutritional value and journey to their final consumers. The present study identifies important challenges emanating at different stages of the food value chain to consumption of one particular neglected and underutilised plant, with certain implications for people's dietary quality, environmental sustainability and biodiversity of natural resources beyond Aponogeton distachyos and SA.

(1)Aponogeton distachyos is a neglected and underutilised aquatic flowering plant native to the Western Cape of South Africa (SA). (2)The plant offers benefits related to people's dietary quality, environmental sustainability and biodiversity of natural resources. (3)Flower's nostalgic connection with local culture and heritage emerge as a key consumption driver. (4)Its unique taste and flavour highly appeal to consumers. (5)Low awareness, limited availability, price and quality are main consumption barriers. (6)There is largely unexploited public policy potential for supporting dietary diversity through growing edible flowers.

The actor-network theory (ANT) has been understood as a method, as a way of engaging in the social world and also transform it. The purpose of this paper is to show the ANT methodological aspects, provide an empirical demonstration of this approach as a method, and promote a debate about the implications and importance of understanding it as a method and not just as a theory.

By analyzing the criticisms of ANT seminal concepts and its repercussions, the authors have offered an understanding of its methodological aspects and its implications for the practice of research. An empirical study conducted in Brazil is presented to exemplify the use of ANT as a method.

The methodological reflection of this approach starts from the recognition that the methods are part of the social world that they research; they are totally imbued with theoretical representations of this world; they are social because they also help to constitute this social world. As a method, ANT seeks to understand the process of stabilizing practices, negotiations and controversies that are established when such practices are in the process of being. In that sense, following the relational disputes that build a practice before their stabilization is the task to be accomplished for the researcher in the field.

The paper offers relevant contributions to the understanding of ANT as a method. The authors encourage other researchers to venture into the development of this approach in future studies that further explore its methodological character.

There are not many studies on ANT as a method. If ANT is also a method, can we apply it to any research? The authors hope to bring this matter to discussion, understanding and questioning the use of this theoretical-methodological approach in the research fields.

This paper aims to propose an effective response by business organizations to the impact of global challenges and sustainable development (SD). It also presents an overview model of organizational performance employing such an approach.

This paper is a conceptual work based upon a review of theories, research findings and reports gathered from relevant literature. The review yielded the following research framework: many countries are facing global challenges; these global challenges are affecting business organizations as external factors; SD is a concept employed to address these challenges; SD can be applied in business organizations through corporate social responsibility (CSR), corporate governance (CG) and sustainability policy and practices; and embedding CSR, CG and sustainability concepts at a strategic level is an effective response to global challenges.

Global challenges are impacting on business organizations and will continue to do so into the future. CSR, CG and sustainability concepts are increasingly being adopted by leading business organizations throughout the world. Embedding CSR, CG and sustainability concepts at a strategic level can sustain long-term organizational performance, as they help businesses face global challenges in a positive manner and maintain their position in societies on good terms with all stakeholders.

Different cultural or socio-economic environments may limit the interpretation and application of the findings or propositions in this research.

How CSR, CG and sustainability concepts can be holistically implemented in business practices.

The role of business in lessening the effect of global challenges and supporting SD is illustrated in the proposed model.

This paper demonstrates connections among the following critical influences on organizational performance: global challenges; SD; and CSR, CG and sustainability.

This study in Iran examined the role of internal and external psychological factors that affected green purchase intention. Moreover, it examined these variables' direct and indirect effects and green purchase intention on green purchase behavior.

An extended version of the theory of planned behavior (TPB) was employed, based on which a theoretical model was designed to reach the authors’ aim. An online questionnaire was used to collect data. For data analysis, confirmatory factor analysis, structural equation modeling, the bootstrapping method and the Preschool Language Scale (PLS) product-indicator approach were conducted to test the proposed conceptual model.

Results show that self-identity, self-interest, self-efficacy and a growth mindset have a positive impact on green purchase intention. However, the study found no predictive effect from peer influence and warm glow. In addition, self-efficacy and green purchase intention significantly affect green purchase behavior. The study reveals that green purchase intention substantially mediates the relationship between self-interest, growth mindset, warm glow and green purchase behavior. Further, warm glow moderates the impact of peer influence, self-identity and self-efficacy on green purchase intention. This study emphasizes the critical role of dispositional factors on green purchase intention and behavior.

Few studies consider the effect of the individual self, a growth mindset, a warm glow and peer influence on green purchase intention simultaneously. In addition, the authors introduced a different version of the TPB model. Further, this research also conducted how these variables, directly and indirectly, affect green purchase behavior.
