In developing countries, agricultural development is still a fundamental means of poverty alleviation, economic development and, in general, sustainable development. Despite the great emphasis on sustainable agricultural development, it seems that there are many practical difficulties towards empirical assessment of agricultural sustainability. In this regard, the present study aims to propose a comprehensive framework for the assessment of agricultural sustainability and present an empirical application of the proposed framework in south-east Iran (Kerman province). The framework is based on a stepwise procedure, involving: (1) The calculation of economic, social, environmental, political, institutional and demographic indicators, covering the actual and potential aspects of unsustainability; (2) the application of Fuzzy Pairwise Comparisons and Analytic Hierarchy Process to construct composite indicators, with the purpose of incorporating the concept of social construct into the assessment process; and (3) the application of Sustainability Maps, diagrams and Barometer of Sustainability for presenting and analyzing the results. The output of the framework is a comprehensive and yet easy-to-understand picture of agricultural sustainability numerically and visually for the selected counties of the province in 2003 and 2015 —via the variety of comparisons and rankings— which allows us to identify the weaknesses and strengths of agriculture in each county in various sustainability levels (comprehensive, overall actual and overall potential, dimensional, and base indicators). It also enables us to monitor and analyze the trends in sustainability changes over the years. By providing such information, this framework can be a useful tool to support agricultural sector decisions that would help planners and policymakers find the right path and move toward sustainability, or modify policies to stay in the right direction over time. Overall, the results suggest that the proposed framework can be an effective tool for the assessment of agricultural sustainability. Of course, it is necessary to examine and validate its capabilities through practical applications in different agricultural areas and systems.

Background: The tourism industry which is one of the most dynamic economic activities in today's world plays a significant role in the sustainable development. Therefore, in addition to paying attention to tourism, sustainable tourism must be taken into huge account; otherwise, the environment and its health will be damaged irreparably. Methods: To determine the level of sustainability in this study, indicators of sustainable tourism were first presented in three environmental health, economic and social aspects. Then, the levels of sustainable tourism and environmental sustainability were practically measured in different cities of Kerman Province using a composite indicator, a linear programming model, Delphi method and the questionnaire technique. Finally, the study cities (tourist attractions) were ranked. Results: Result of this study showed that unfortunately the tourism opportunities were not used appropriately in these cities and tourist destinations, and that environmental aspect (health and environmental sustainability) had very bad situations compared to social and economic aspects. In other words, environmental health had the lowest levels of sustainability. Conclusions: The environment is a place for all human activities like tourism, social and economic issues; therefore, its stability and health is of great importance. Thus, it is necessary to pay more attention to sustainability of activities, management and environmental health in planning sustainable development in regional and national policy.

Serious constraints in increasing water supply have led countries around the world to seek solutions for managing water demand. Proper pricing of water is one of the foremost water demand management policies which can lead to the optimal water use. On the flip side, the quality of agricultural water is declining due to the uncontrolled abstraction of groundwater. In this regard, the present study aims to determine the economic value of different qualities of water throughout pistachio-growing regions of the Rafsanjan-Anar plain in Iran. Results reveal that the economic value and price elasticity of water demand differ among different groups. Freshwater, moderately saline water and highly saline water have the highest to lowest elasticity and shadow price, respectively. Additionally, comparison of the gross margin, which represents the profit from each activity, in two conditions including the unsustainable status quo and sustainable conditions intended by the Ministry of Energy, shows that although water use has declined by 50%, the gross margin has decreased by only 36%. This implies it is feasible to reduce water use in pistachio orchards by water re-allocation with a minimum decline in profit, which will both reduce water use and ensure high economic benefits for farmers.

Allocating effluent of wastewater treatment plants to users of economic sectors and satisfying their requirements has created a challenging debate and a need for prioritization. This study assesses the importance of sectors that utilize treated wastewater (TWW) using risk and social acceptability indexes based on expert-oriented approaches. Considered sectors are agriculture, industry, urban green space and natural resources and the study area is located in Iran, around the Isfahan North Wastewater Treatment Plant. The risk index is calculated using Frank and Morgan model and consequently TWW use in the industrial sector is less dangerous than other sectors. Moreover, the social acceptability index, which was determined using Mamdani fuzzy inference set, indicates higher acceptability of TWW use in natural resources sector compared to other sectors. By constructing the conceptual model, generating the decision matrix and using the results of grey relational analysis decision-making model for the four sectors, the allocation priorities of TWW became industry, natural resource, green space, and agriculture respectively. It is suggested that Water and Wastewater Company grant the permission of TWW use to water-consuming industries and man-made forests development, which result in increasing employment, reduction of harmful effects of dust, and water consumption decrease.
