Potential water savings associated with agricultural water efficiency improvements: a case study of California, USA
This study analyzes the potential for water savings from irrigation efficiency improvements in California, USA. We model water savings associated with three efficiency scenarios in wet, average and dry water years. The ‘efficient irrigation technology’ scenario shifts a fraction of the crops from flood irrigation to sprinkler and drip systems; the ‘improved irrigation scheduling’ scenario uses ...

Implications of water policy reforms for virtual water trade between South Africa and its trade partners: economy-wide approach
This paper employs an economy-wide framework to evaluate impacts of water and trade policy reforms in South Africa (SA) on virtual water flows. To pursue this analysis, the study derives net virtual water trade flows between SA and its partners to assess implications of recent trade agreements within the South African Development Community compared to economic cooperation with other major ...

Comparative research on water and energy-saving irrigation systems in the GAP and Aegean regions of Turkey
This research was carried out to determine the effects of furrow, sprinkler, drip, mobile nozzle, mobile drip and LEPA (Low Energy Precision Application) irrigation methods on the yields and Water Use Efficiency of cotton in the South Eastern Anatolian Project (GAP) Area and in the Aegean Region. According to the results obtained, the highest yield was produced from the drip irrigation method. ...

Irrigation and Nitrogen Best Management Practices Under Drip Irrigated Vegetable Production
Abstract Plastic mulch and drip irrigation are commonly used in high intensity vegetable production regions such as Florida. Drip irrigation can be much more efficient than sprinkler irrigation since only the root zone of the cropped area is irrigated. However, improper irrigation management can lead to wasted water and leaching of soluble chemicals such as nitrate. In this project, several ...

Drip Irrigation Meets Drivable Grass
Drivable Grass® has originally been designed with the intention to have commonly used spray irrigation systems installed underneath the product, including fitting sprinkler heads through cut voids of the mat or spraying from outside the installation. The conventional overspray irrigation system has been used successfully with Drivable Grass® for many years. Soil Retention, manufacturer ...

Irrigation challenges in the sub-humid US Mid-South
Irrigated area in the Mid-South USA continues to increase and now totals four million ha. Because of low available water holding capacities and shallow root-limiting layers in many soils, irrigation management is difficult. Water quality and water use efficiency impacts under irrigation are poorly understood, but comprehension is necessary if conversion from groundwater to surface water supplies ...

Can We Prevent A Food Breakdown?
By Lester R. Brown As food supplies have tightened, a new geopolitics of food has emerged—a world in which the global competition for land and water is intensifying and each country is fending for itself. We cannot claim that we are unaware of the trends that are undermining our food supply and thus our civilization. We know what we need to do. There was a time when if we got into trouble ...

Reuse of Dairy Lagoon Wastewater Through SDI in Forage Crops
Abstract California has become the leading dairy products producing state in the USA. This has resulted in farms commonly milking several thousand cows per day. The care and feeding of the animals has produced large waste streams commonly collected and stored in lagoons. Environmentally safe handling and reuse of the lagooned wastewater is the objective of this study. A system of Subsurface Drip ...
