The Effect of Degradation of Groundwater Resources On Capital of Pistachio Growers in Kerman Province

Abstract

Real cost evaluation of water is necessary in agricultural products depending on obtained value by this input. In most areas of world especially in arid and semiarid areas, exist over pumping of ground water because the real value of water is much most than the costs of water supply and the lack of fit management water resources. In this study, using a sample of 110 farmers, water dealing value of over using of groundwater in Rafsanjan pistachio production area were investigated. Analysis and regression methods were used in this regard. The average determined value obtained 24 cents, for each share of water in this region which with over drafting of ground water, and decreasing quality and quantity of water has had significant relationship in the one percent significance level. Finally, for elimination or reduction of ground water degradation and its effects, this paper recommended in addition to reduction of licenses for ground water pumping. Determination of optimal economic water/land ratio in new and old pistachio producing areas is the other proposal of this research for alleviation groundwater over drafting effects. Permission for water conduction between wells and combination of fresh and saline water and also using desalination systems are methods for solving low quality of ground water.

Study on hydrochemical characterization and annual changes of surface water quality for agricultural and drinking purposes in semi-arid area

“…Based on Table 4, correlation coefficients between total hardness (TH) and Ca, Mg, Na, Cl, and HCO 3 were statistically significant at the 0.01 level (r = 0.85, 0.91, 0.87, 0.91, and 0.86), respectively. The results of many other studies also corroborated the results of present study (Rahnama and Zamzam 2013;Mortazavi et al 2014;Hosseinifard and Aminiyan 2015). Salehi and Hosseinifard (2012) reported high positive correlation among EC, Na ?…”

“…The pH values of water in the Givdari River varied between 7.3 and 7.7, indicating slightly alkali water. The achieved results Mortazavi et al (2014) and Hosseinifard and Aminiyan (2015) supported these results. According to the WHO guidelines, pH \ 6.5 or [9.2 would markedly impair the potability of drinking water (WHO 2011).…”

“…(r = 0.69) in Razan, Hamadan region (Jalali 2009). The Na-Cl relationship has often been used to identify the mechanisms for acquiring salinity and saline intrusions in semi-arid regions (Mortazavi et al 2014). A parallel enrichment in both ions indicate dissolution of chloride salts or concentration processes by evaporation (Jalali 2010).…”

Investigation of Groundwater Quality and Its Suitability for Drinking and Agricultural Use in the South Central Part of the Coastal Region in Bangladesh

“…The recommended fertilizers used for agriculture may be the source for the prominent concentration of nitrate in some locations (Chandna et al 2010). The mean value of Mn in both pre-and post-monsoon seasons were 0.50 and 0.66 mg/l, and it was above WHO guideline for drinking water (\0.05 mg/l).…”

The Role of Urban Agriculture Technologies in Transformation toward Participatory Local Urban Planning in Rafsanjan

“…During the past decade, the government of Iran has emphasized changing their conventional agricultural systems, such as those used in the city of Rafsanjan [7]. Agriculture is the most important economic activity in Rafsanjan, being one of the largest pistachio production centres in the world [8]. Pistachio farms, agricultural centres and pistachio markets dominate rural areas, as well as built-up spaces in urban and peri-urban areas [8,9].…”
