A Systems Engineering Approach to Viticulture On-Farm Irrigation
Water resources management presents an important research topic, because our planet is facing a serious water crisis. About 70% of all fresh water usage goes towards agriculture. Moreover, low water application efficiency are well reported in the literature. Improving on-farm irrigation efficiency can make a substantial contribution to a more sustainable utilization of the world’s fresh water r...
متن کاملDeterminants of Choice of Irrigation Technology and Farm Income
For the purpose of the study, it is important to analyse the determinants of irrigation technology choices and farm incomes. Fig. 1 below illustrates how the past condition of power supply and the expectations regarding the future along with farm and region specific characteristics affect the choice of irrigation technologies. The choice of a specific irrigation technology, in turn, together wi...
متن کاملFarm-Level Risk Management Using Irrigation and Weather Derivatives
An agronomic crop growth model—the Decision Support System for Agro-Technology Transfer—and a constant relative risk aversion utility function are used to examine corn irrigation strategies in Mitchell County, Georgia. Precipitation contracts are designed to help farmers manage risk. Three conclusions originate from the findings. First, the optimal irrigation strategy can greatly increase produ...
متن کاملReview of whole-farm economic modelling for irrigation farming
The main objective of this paper is to review the progress that has been made in South Africa with respect to whole-farm economic modelling over the past 2 decades. Farming systems are complex and careful consideration to the stochastic dynamic nature of irrigation farming processes and their linkages with the larger water system is necessary when conducting whole-farm modelling. Both simulatio...
متن کاملA genetic algorithm for optimizing off-farm irrigation scheduling
This paper examines the use of genetic algorithm (GA) optimization to identify water delivery schedules for an open-channel irrigation system. Significant objectives and important constraints are identified for this system, and suitable representations of these within the GA framework are developed. Objectives include maximizing the number of orders that are scheduled to be delivered at the req...
