Home composting is judged as an effective municipal waste management option in which household contribution is essential, but it has a low adoption. The objectives of the study were to determine the factors that influence home composting intention and identify the moderating role of composting knowledge in the model, using the combined model of the theory of planned behavior (TPB) and norm activation model (NAM). A structured questionnaire was applied to a sample of 367 residents of Isfahan city, Iran, randomly selected. Data were analyzed using cluster analysis, discriminant analysis, PLS-SEM, and PLS-MGA. Cluster analysis grouped the three clusters based on the constructs of the integrated model, and this result was confirmed by discriminant analysis. Findings show that attitude, subjective norm, and perceived behavior control can predict the intention to compost. Study results confirmed the positive effect of awareness of the consequences of composting on ascribed responsibility to compost at home, of responsibility to the personal norm, and of the personal norm on intention to compost at home. Furthermore, it was observed that composting knowledge moderates the relationship between subjective norm and behavioral intention, and the one between perceived behavioral control and behavioral intention. The integrated model had more predictive power than the TPB model. The fit statistic of the integrated model was good and 71% of the variance for intention behavior toward home composting. The insights on factors affecting residents’ intention to compost obtained from this study can be used in measures and programs that reinforce and stimulate home composting.
One of the most important environmental problems in Iran is the destruction and drying of Urmia Lake (UL). UL is one of the main causes of suitable weather for agricultural boom and tourist attraction and it should be considered that the villagers exposed to UL drying have a strong dependence on vulnerable resources such as water, air, soil and plants for their livelihoods and have low adaptive capacity with this crisis for reasons such as poverty, lack of awareness and lack of infrastructure. This study was designed to evaluate the vulnerability of rural households to UL drying in the Shabestar region. The vulnerability was calculated based on Intergovernmental Panel on Climate Change (IPCC) definition and using vulnerability index (VI). Research population included rural households of Shabestar region (N = 19,249) and about 347 households were selected as the research sample using multistage cluster sampling technique. Results showed that the average score of respondents was 0.455 (moderate) in exposure, 0.359 (moderate to low) in sensitivity, 0.404 (moderate to low) in adaptive capacity and finally, the vulnerability index (VI) was 0.470 (range of 0 to 1). 12.8% of households had low, 70.5% had medium and 16.7% had high vulnerability towards UL drying.
Water shortages in rice production represent a formidable challenge for the world’s food, economic, and social security. Water is the most important single component for sustainable rice growth, especially in the world’s traditional rice-growing areas. Therefore, this study attempts to evaluate the improvement of rice water productivity in Northern Iran on the basis of Strengths, Weaknesses, Opportunities, and Threats (SWOT) analysis. This study is a qualitative-descriptive survey. A random sampling method was used to determine the sample size, and finally, 105 male and female rural facilitators in Sari city (the capital of Mazandaran Province located in Northern Iran) were surveyed. The results showed that the development of appropriate infrastructure, increasing new irrigation and drainage networks with the aim of increasing the use of efficient water technologies, was the most important strategy. The most necessary strengths, weaknesses, opportunities, and threats to improve the water productivity and management of paddy farms in the study area are, respectively, as follows: “fertile paddy fields and relatively good soils in most areas”, “weakness in the participation and interaction of users in water resources projects and paying attention only to the physical development of irrigation networks and ignoring the issues of network operation and farmers’ participation in the management”, “improving irrigation planning”, and “surplus harvest from Tajan River and drop in water level”. Obtained findings may be used to address water scarcity and water quality management issues in the agriculture sector. The results demonstrate that, under potential climate change and water shortages, SWOT may be seen as a guide for contingency initiatives.
