Abstract and Figures

In the United States, urban population growth, improved living standards, limited development of new water supplies, and dwindling current water supplies are causing the demand for treated municipal water to exceed the supply. Although water used to irrigate the residential urban landscape will vary according to factors such as landscape type, management practices, and region, landscape irrigation can vary from 40% to 70% of household use of water. So, the efficient use of irrigation water in urban landscapes must be the primary focus of water conservation. In addition, plants in a typical residential landscape often are given more water than is required to maintain ecosystem services such as carbon regulation, climate control, and preservation of aesthetic appearance. This implies that improvements in the efficiency of landscape irrigation will yield significant water savings. Urban areas across the United States face different water supply and demand issues and a range of factors will affect how water is used in the urban landscape. The purpose of this review is to summarize how irrigation and water application technologies; landscape design and management strategies; the relationship among people, plants, and the urban landscape; the reuse of water resources; economic and noneconomic incentives; and policy and ordinances impact the efficient use of water in the urban landscape.

Answer 2

Explanation:

Crop water-use or ET includes water that directly evaporates from soil and plant surfaces when wet (evaporation or E) and water that is transported through plant tissues from the soil via the roots, stems and leaves (transpiration or T). Crop ET varies with crop species and variety, plant size or growth stage, plant health, and weather (air temperature, humidity, solar radiation, and wind). With adequate soil water, ET increases as plant green leaf area, air temperature, wind speed, and solar radiation increases and as relative humidity decreases (i.e. the air becomes drier). Early in the growing season, plants are small and ET is low (0.05 inch per day or less). During mid-summer, as plants grow to their maximum size, ET increases to a peak value (i.e. 1/3 inch per day or more). Later in the season, as plants mature and begin to senesce (dry down), ET begins to decline, even though plant size may be large. Figure 1 shows the average daily water-use or ET of alfalfa in the Four Corners area based on measurements taken during a multiple-year study at New Mexico State University’s Agricultural Science Center at Farmington.
