Freshwater is a vital resource for both ecosystem health and human survival, and it is the natural resource that is the most extracted at the global level. Excessive freshwater consumption can be responsible for a scarcity in the circulation rate, which occurs when the freshwater demand exceeds its availability. Hence, water consumption needs to be optimised in all human activities, given the increasing freshwater scarcity due to climate changes and to the annual net increase in the human population of 81,000,000. Freshwater plays many important roles in daily life for example, agriculture is responsible for nearly 70% of that withdrawal volume, and it is therefore, the most water-intensive sector. This puts emphasis upon the urgent need of transitioning towards more sustainable agricultural and food-production/consumption systems. Water Footprint (WF) is increasingly playing a guiding role in that context. Indeed, it makes it possible to quantify water consumption and related environmental consequences. With the objective of contributing to enhancement of research and of supporting practitioners and decision-makers in environmentally sustainable and resilient food production/consumption, the authors of this article addressed the relevant issues connected with: a) physical and economic water scarcity in agriculture, b) practices and tools to reduce water wastage, c) WF assessment methodologies. A number of environmental, economic, and engineering solutions were proposed to mitigate water scarcity. The improvement of irrigation technologies and practices was identified as an important major way to reduce water scarcity. Additionally, solar powered ‘reverse-osmosis’ is being used in many parts of the world to produce irrigation water from saline water, thereby reducing the need to extract freshwater from underground aquifers. This article confirmed the importance of research on water scarcity; moreover, it can stimulate development and application of solutions that make agricultural production/consumption more efficient and resilient.

Summary: This article analyzes the mass of the materials that flowed through the Italian economy during 1994 and compares the results with a similar analysis of Germany, Japan, the Netherlands, and the United States published by a collaboration headed by the World Resources Institute. In order to perform this comparison, we have evaluated the mass of the materials produced within the country and the mass of the imported materials and commodities. For the domestic production, imports and exports, we have also evaluated the mass of the materials that accompany—as “hidden flows”—each physical flow. Our analysis indicates that, in 1994, Italy experienced total material requirements (TMR) of 1,609 million metric tons (Mt), of which 727 Mt was used as direct material input (DMI). A comparison with other developed countries shows that the TMR and DMI flows, measured in mass per person and in mass per GDP unit, are, in Italy, lower than the corresponding figures evaluated for the United States, Germany, and the Netherlands. An interpretation of these results is presented. The analysis may give information useful for environmental considerations, although the limits of such an approach are made clear.

Purpose: The paper aims to study the main managerial factors for evaluating the eco‐cluster approach and to promote their implementation within the environmental industry management.Design/methodology/approach: The paper includes the authors' observations about the advantages of eco‐clustering, and their practical consideration. The empirical research shows the tendencies for developing an eco‐cluster policy in one of the most economically dynamic regions in Bulgaria: Varna‐Devnya. The study framework was discussed with managers on the basis of the environmental practices of Solvay Sodi, Devnya Cement, and Agropolihim JSC. The authors outline the possible cycle of waste management and emission exchanges in that industrial zone.Findings: The findings show that the eco‐cluster concept in Bulgaria could be provided on micro‐ and macro‐managerial levels, discussing firm relationships and governmental policy. The principal limitation for generating the findings is the lack of concordance between the governmental interest and the business interests of the TNCs. Three negative factors are important in the implementation of the eco‐clustering concept: lack of information; financial constraints; lack of trust.Practical implications: Common strategic agreements between TNCs and local authorities provide useful managerial and public implications for eco‐clustering. Second, the analysis outlines essential steps for the managerial behavior for creating eco‐clusters.Originality/value: The perspectives of the eco‐cluster are studied for the first time in Bulgaria. The investigation gives motivation for a further study of the eco‐clustering approach with the support of the local authorities. The practical steps for managerial and public implications of the eco‐cluster concept as an innovative tool for Bulgarian managers are revealed.
