Evaluation of Virtual Water and Water Footprint of Crop Production (Case study: Qaleganj County)
To address the optimal use of available water resources, a revisit of water resource allocation and management is needed. Water use and water footprint of every product varies in different geographical areas due to various climate, agricultural operations and water efficiencies. Thus, more productive management schemes are to be developed. The goal of this study is to assess the virtual water a...
متن کاملSpatiotemporal Correlations between Water Footprint and Agricultural Inputs: A Case Study of Maize Production in Northeast China
To effectively manage water resources in agricultural production, it is necessary to understand the spatiotemporal variation of the water footprint (WF) and the influences of agricultural inputs. Employing spatial autocorrelation analysis and a geographically weighted regression (GWR) model, we explored the spatial variations of the WF and their relationships with agricultural inputs from 1998 ...
متن کاملSensitivity and uncertainty in crop water footprint accounting: a case study for the Yellow River basin
Water Footprint Assessment is a fast-growing field of research, but as yet little attention has been paid to the uncertainties involved. This study investigates the sensitivity of and uncertainty in crop water footprint (in m3 t−1) estimates related to uncertainties in important input variables. The study focuses on the green (from rainfall) and blue (from irrigation) water footprint of produci...

15 صفحه اولModeling crop cultivation pattern based on virtual water trade: evidence from Marvdasht in southern Iran
ABSTRACT- This study aims to model optimal cultivation pattern based on the maximization of importing virtual water and social net income of major crops in Marvdasht, Iran. For this purpose, a linear programming model was developed considering constraints of virtual water and land limitations followed by other models to include employment restrictions. Based on the findings, wheat and tomato we...
