This study aimed to investigate the vulnerability of Sistan plain to fluctuations and Water Scarcity in Hirmand River using the vulnerability framework, by applying the resilience approach. The socioeconomic and biophysical components presented in this framework were embedded in a set of subsystems of the System Dynamics (SD) model. According to this, four levels of reference resilience were de...
Identification and sequence analysis of grain softness protein in selected wheat, rye and triticale.
Grain softness protein (GSP) is an important protein for overcoming milling and grain defenses in the innate immunity systems of cereals. The objective of this study was to evaluate and understand GSP sequences in selected wheat, rye and triticale. Using sequences for this gene from a sequence database, we performed clustering analysis to compare the sequences obtained from 3 germplasms wi...
Finding the appropriate parents for breeding programs is the main aim of selecting in drought tolerant crops and landraces under stresses conditions. In present survey, eigthey wheat landraces and varieties from different areas of Iran were evaluated in Gorgan agricultural research station (as a normal or potential yield) and Mazrae-Nemoneh (as under stress condition) during two years (1999-200...
This paper investigates the hydro-climatic reasons behind desiccation of Hamun Lakes in Iran-Afghanistan border. We analyzed changes flow Hirmand River (90 percent total inflow to lakes) at international border, and precipitation over this river’s sub-basin during 1960–2016 by calculating standardized indices for (SPI) discharge (SDI). applied Normalized Difference Spectral Indices using satell...
The present study conducted to investigation the forage quality and germination status of Capparis spinosa in Niatak Hirmand rangelands. Forage quality indices were analyzed by four replications on three phenological stages (vegetative, flowering and maturity stages) randomly. The experiment included 19 treatments to improve seed germination condition. Treatments included physical such as scrap...
The Sistan Plain for a long time has faced hazards of flood, drought and sandstorm. Also due to existence of abundant water resources it had been one of the important places for men’s placement. So far, no comprehensive study has been done on environmental hazards which would include ways to overcome or decrease their impacts in Achaemenid era. The present survey aims for studying the reciproca...
the climatic conditions of sistan plain and its coexistence paved the way for settlement of human populations, establishment of various residential sites and perhaps more importantly, emergence of civilizations that have given rise to the great cities such as shahri-sukhteh and tang-e gholaman. although the accumulation of residential areas in the plain during different times and their proxim...
there are different materials and compounds in water that determine its chemical and physical quality. as the result of special conditions such as increase and decrease in discharge, water quality can vary. one of these conditions is drought that decreases discharge, and water quality changes. in this study, droughts of sistan and baluchistan province have been analyzed using standardized preci...
In this study, water management allocated to the agricultural sector’ was analyzed using stochastic dynamic programming under uncertainty conditions. The technical coefficients used in the study referred to the agricultural years, 2013-2014. They were obtained through the use of simple random sampling of 250 farmers in the region for crops wheat, barley, melon, watermelon and ruby grapes under ...
