Climate change is one of the most pressing global issues of the twenty-first century. This phenomenon has an increasingly severe impact on water resources and crop production. The main purpose of this study is to evaluate the impact of climate change on water resources, crop production, and agricultural sustainability in an arid environment in Iran. To this end, the study constructs a new integrated climate-hydrological-economic model to assess the impact of future climate change on water resources and crop production. Furthermore, the agricultural sustainability is evaluated using the multicriteria decision making (MCDM) technique in the context of climate change. The findings regarding the prediction of climate variables show that the minimum and maximum temperatures are expected to increase by about 5.88% and 6.05%, respectively, while precipitation would decrease by approximately 30.68%. The results of the research reveal that water availability will decrease by about 13.79–15.45% under different climate scenarios. Additionally, the findings show that in the majority of cases crop production will reduce in response to climate scenarios so that rainfed wheat will experience the greatest decline (approximately 59.95%). The results of the MCDM model show that climate change can have adverse effects on economic and environmental aspects and, consequently, on the sustainability of the agricultural system of the study area. Our findings can inform policymakers on effective strategies for mitigating the consequences of climate change on water resources and agricultural production in dry regions.

Energy is an important factor in boosting and sustaining the economic growth level of a country. The aim of this study was to investigate the relationship between energy consumption and the economic growth of selected developed and developing countries from 1993–2019. For this purpose, we used the Pedroni co-integration method to determine the long-term relationship between economic growth and energy consumption. To estimate the long-term parameters, the panel fully modified OLS method and the Dumitrescu and Hurlin heterogeneous panel causality estimation technique were used, and the causality direction between variables was considered. The results showed that energy consumption had a positive and significant effect on the economic growth of both groups of countries. The causality analysis revealed the existence of a protection effect between renewable energy consumption and economic growth in developed countries. Hence, policies that lead to an increase in independent growth in these countries can effectively impact their growth. On the other hand, the existence of the feedback effect in developing countries shows that storage policies and reduced energy consumption may pose a threat to economic growth in these countries.

In recent decades, meat consumption has increased globally due to increased incomes. A consequence of increased red meat consumption has been the rise in greenhouse gas emissions and nutrition-related diseases. Consumption of antibiotic-free (ABF) poultry meat is a viable healthy and sustainable substitute that will cause less damage to humans and the environment in the long run. This study was undertaken due to the increasing importance of healthy food consumption to preventing nutrition-related diseases. The health food industry is still in its preliminary stages; for market development of organic broiler meat and movement toward sustainable production of ABF meat, the first necessary step is conducting empirical research on ABF poultry meat consumption and identifying factors that influence household consumption patterns of ABF poultry meat. Therefore, the objectives of this study were the investigation of factors affecting poultry meat consumption by consumers and ABF poultry meat preference. Comparing the results could reveal what percentage of consumers are able to buy healthier higher-priced antibiotic-free poultry meat. Data were collected from 360 completed questionnaires completed by households from the city of Mashhad, Iran via simple random sampling in 2021. To investigate the first objective, an ordered logit model was used. The results showed that age, the head of household’s education, awareness of the nutritional benefits of poultry meat, advertising, and family income were statistically significant determinants of poultry meat consumption. To investigate the second objective, since some consumers cannot buy ABF poultry meat due to the higher prices, we used a two-step Heckman model. The results showed that the awareness of the nutritional benefits of ABF poultry meat, the head of household’s education, monthly family income, and advertising had positive impacts, with prices having a negative impact on the amount of antibiotic-free poultry meat consumed by the households. Comparing the results of the two models revealed that only about 30% of consumers could buy ABF poultry meat, mainly due to the higher prices. This study recommends improving consumer awareness, targeted distribution of ABF poultry meat according to customers’ economic and demographic characteristics, affordable prices, and appropriate marketing tools for sustainable consumption of ABF poultry meat.

Entrepreneurship and innovation are the fuel of economic growth. Understanding the motivational factors that lead to the success of entrepreneurs in agribusiness can be useful in affecting the degree of successful investment that accelerates development and economic growth in the agriculture sector. In this study, we investigated the factors affecting the success of entrepreneurs in the agribusiness sector in Mashhad, Iran, using a two-stage Heckman approach. Factors affecting the success or failure of agribusiness entrepreneurship have received less attention in the literature. In this study, the aim was to determine the factors affecting agricultural entrepreneurship success and entrepreneurs’ profits. We generated the data for this study by designing a questionnaire and conducting a survey of active entrepreneurs in Mashhad in 2020. The results showed that entrepreneurship experience, risk-taking behavior, interest rates, and initial capital have a significant impact on the probability of entrepreneurship success and entrepreneur’s profits. Policies that could improve the skills of entrepreneurs, provision of initial capital requirements, and financial market efficiency had an effective role in increasing entrepreneurship and innovation in the agribusiness sector. Entrepreneurs in the field of agriculture could consider these factors to have better choices while entering or continuing with their agribusinesses. Our recommendation to policymakers and agribusiness leaders is to establish a friendlier and more stable environment for entrepreneurship and employ policies that help reduce the risk of entrepreneurs’ initial investment returns.

Democracy has both a direct and an indirect relationship with sustainable development. Democracy is related to the movement toward long-term economic development directly, and indirectly, democracy can provide the means to create the institutional structures needed to create links between the political systems, the culture of participation, and the social values of a society. Since economic development is a multidimensional concept and one of its primary requirements is to achieve a high level of income and appropriate economic growth, knowing the relationship between democracy and economic growth is especially important for policymakers. Many important questions are raised about the relationship between democracy and economic performance. What is the relationship between democracy and economic growth? Is this relationship different in developed countries and developing countries? Considering the effects of democracy and economic growth on the welfare of communities, the main purpose of this study was to investigate the causal relationship between democracy and economic growth from 1990–2020 for the OECD and selected developing countries. The results showed that the conflict and skeptical hypotheses had been established in OECD and developing countries, respectively. It was concluded that the pattern of economic growth and development in OECD countries differed from that in developing countries. For OECD countries, real per capita GDP growth was mainly affected by previous per capita GDP growth, and the effect of democracy on per capita economic growth was negative. Moreover, the results indicated that in developing countries, democracy alone had not triggered economic growth and that real per capita GDP growth depended on other important structural variables such as social and physical infrastructure.
