Abstract

The purpose of this study was to evaluate the effect of different levels of water consumption reduction in different growing stages as deficit-irrigation scenarios based on economic, social, and environmental criteria in line with agricultural sustainability of the Qazvin irrigation network. In order to maximize farm income, the positive mathematical programming (PMP) method along with the maximum entropy (ME) were used on the basis of crop yield response functions comparing to water in the space of other constraints. Then, the analytical hierarchy process (AHP) method was hired to calculate the weight of the major indices and their sub-indices, and in the final stage, the best-ranked scenarios were selected using Technique for Order Prefer

Abstract

The watershed, a dynamic and integrated social, economic, and biological system, plays an important role in the growth and development of the economy. Watersheds as a basis to support natural life and human activities have been heavily damaged over the past few centuries. One of the major causes of which is the inappropriate land-use allocation. Studies on land-use allocation mostly investigate optimization methods apart from each other but combining different approaches and comparing outcomes of different methods seems to be more helpful, especially for the decision-makers in a watershed. Hablehroud watershed as an important agricultural production region in Iran has been facing different ecological and economic problems during recent deca

Abstract

Introduction: ?Sustainable development policies are designed to be consistent with production processes and environmentally friendly products and to have the least negative impact on the environment. The tools needed to implement these policies are to have the amount and price of the inputs on one side and to have the amount and price of the desired and undesirable output on the other hand. Since the prices of undesirable products in the production process are not available, it is necessary to estimate these prices. The concept of the shadow price of each unit of undesirable output is that if an additional unit is produced from this output, what additional cost will be imposed on the community including the reduction of desired production o

Abstract

Water is the most important input used in agriculture. Due to the scarce water resources and dry and semi-arid climatic conditions of Iran, water demand management has special importance in the whole economy, including the agricultural sector, because this sector has the largest share in water consumption. The purpose of this study was to estimate the water demand function and to analyze the cross and symmetrical relationships between water and other inputs. For this purpose, the Ordinary, Allen, and Morishima's substitution elasticity were calculated, and the substitution and complementary relationship between water and other inputs were determined. These elasticities determine the amount and sign of cross relationship of water. In order t

Abstract

The self-sufficiency policy for wheat production in Iran has increased external costs for the country besides causing the destruction of water and land resources. Nevertheless, due to various political, economic, and socio-economic reasons, self-sufficiency in wheat production in Iran is a binding policy. According to statistics, an average of about 67 percent of wheat production across the different regions of Iran is irrigated wheat. Thus, in this study, the effect of a guaranteed price policy on the distribution of irrigated wheat land-use in Iran during the period 2001–2016 was evaluated with an emphasis on the role of the regional differences using the pooled mean group approach. The results indicated that, in the long run, the incre

Abstract

The present study evaluated the potential impacts of climate change of Hamadan-Bahar plain on dimensions including economical, physiological, hydrological and meteorological aspects. The results showed that climate change in the region has negative impacts on the agricultural sector by reducing the crop yield as well as groundwater balance. In the most optimistic scenario on the horizon of 2090, rainfall and groundwater levels would reduce by 14.4 and 12.3 %, respectively and the average temperature would rise by 14.7 %. Accordingly, the economic value of water would increase by 44 % and the agricultural value-added (net income) would fall by 19 %, indicating the intensification of water shortage crisis and agricultural recession. Also, the

Journal PapersEnvironmental Geochemistry and Health , 2020 August 28, {Pages 12-Jan }

Abstract

One of the most important factors in the agricultural sector is the supply of water. There are numerous factors affecting the supply of water in the agricultural sector. One of these factors is urban development. After the agricultural and industrial revolution, urban revolution is one of the most important issues in the economic development of countries. Urban development has two implications for agricultural water use; this both increases the demand for agricultural crops and the consumption of water in the household sector, which both lead to a reduction in available water in the agricultural sector. Therefore, determination of the impact of urbanization on water consumption in agriculture is necessary. In this study, we have examined th

Abstract

Promoting water productivity in food production is one of the main issues in different countries of the world, especially in low-water countries like Iran. In the present situation, measurement and analysis of productivity indices of scarce water input in agricultural sector in Iran is of special importance due to the quantitative and qualitative limitation of this valuable material. Therefore, the purpose of the present study is to measure and compare the physical and economic productivity of irrigation water use in two traditional and modern irrigation systems for major crops (Wheat, Barley, Rapeseed, Alfalfa and Forage Corn) in Shahriar. In this study, the CPD, BPD and NBPD were used to calculate of agricultural water productivity. Accor

Journal PapersEnvironmental monitoring and assessment , Volume 191 , Issue 3, 2019 March 1, {Pages 134 }

Abstract

This research evaluated climate change impacts on water resources using soil and water assessment tool (SWAT) models under representative concentration pathway scenarios (RCP 2.6, RCP 6, RCP 8.5). First, drought intensity was calculated using the standardized precipitation index (SPI) for the period 1987–2016. Then, the coefficients of precipitation as well as minimum and maximum temperature changes were simulated as SWAT model inputs. The results revealed that temperature will rise in future periods and the precipitation rate will be changed consequently. Then, changes in runoff during periods of 2011–2040, 2041–2070, and 2071–2100 were simulated by introducing downscaled results to SWAT model. The model was calibrat

Abstract

In the recent decades, water resources have been severely under pressure due to increasing demand. Besides, use of water by some users affects the possibility of using water by other users. Therefore, the optimal management and allocation of water resources have become increasingly important among policymakers and farmers. Undoubtedly, one of the most important tools for optimal allocation of water resources is economic valuation which the long-term development strategy of the country also emphasizes it. In this regard, the aim of the present study was to determine the economic value of agricultural water from the viewpoint of the applicants in wheat and rapeseed farms of Qazvin flat irrigation network area using the production function app

Journal PapersEnvironmental Processes , 2019 November 12, {Pages 15-Jan }

Abstract

Climate changes seem to have adverse impacts on food security. Oilseeds are the second largest food group in the world after cereals. Soybean is the main oilseed crop in Iran mainly cultivated for edible oil and meal. The potential effect of climate change on soybean production is, however, not well addressed. This study aimed to quantify the effects of climate change on soybean yield in major producing provinces in Iran using the panel econometric approach and the General Climate Models (GCMs). For this purpose, the climatological data of three meteorological stations, i.e., Ardabil, Golestan, Mazandaran were gathered over 1980–2012. Besides, the soybean economic data obtained from Iran Ministry of Agriculture were used. LARS-WG 6.0 was
