In the Phoenix, Arizona, U.S., metropolitan area, community associations with legally binding covenants, codes, and restrictions (CC&Rs) impose limitations on landscaping activities in many new neighborhood residential communities. Studies were conducted in the Phoenix area to develop an understanding of residential homeowner landscape preferences and practices and how they might be impacted by...

Relatively little research has been expended on developing plants for use in urban desert landscapes or “xeriscapes.” However, because of reduced availability and increased cost of water, water conservation needs, and concerns for our environment, increased awareness and demand for arid-adapted landscape plants have developed. An especially important need is for groundcover requiring little wat...

the purpose of this study was to evaluate the species-environment relationships in arid and semi-arid rangelandsof nodushan, yazd. the plant species cover and the environmental variables were measured at 9 sites. soil sampleswere taken for measurement of 12 attributes in 0-10 cm and 10-80 cm layers. vegetation was classified using twowayindicator species analysis (twinspan). data was analyzed u...

at the beginning of twenty-first century, the water crisis in the priority policy andmanagement is inside and outside of the country as principle thoroughly human, social,economic and political rulers of the country is considered abundant. the world bank hasannounced that during 1960 and 2025, water resources in middle east, from 3430 m3 for theeach person in year reach to 667 m3 because of pop...

The article is devoted to the study of ways achieve sustainable development landscaping and microclimate in architecture multi-storey residential complexes arid zones on example city Nukus. Their town-planning, space-planning functional solutions are considered.

the objective of this research was to investigate the effects of deficit irrigation on physiological and agronomic terms of eggplant to maximize the water use efficiency (wue) without affecting the final yield and fruit quality parameters under arid environment. therefore, two field experiments were conducted at two different sites: ghor al-safi, jordan valley and sail al-karak, karak valley, ka...

soil compaction has become a widespread problem in the world and is one of the factors involved in land degradation and declining crop yields, especially in the arid and semi-arid agriculture. the purpose of this study was to investigate the effects of subsoil compaction on morphological, physiological and agronomic aspects of wheat .the research was carried out in the experimental farms of anb...

Based on the combined use of satellite remote sensing and geographical information systems(GIS), as well as field investigation, the land-use change dynamics and the interaction between these changes are analyzed in the Zuli River Basin located in semi-arid Loess Plateau China during the period of 1987-2005, which with typical farming-pastoral region feature of northern China. The land-use chan...

Estimating actual crop water requirement and irrigation schedule are essential for designing of the irrigation systems, storage construction and water conveyance structures. Many models have developed for estimating crop water requirement. Although most of these methods need different climatic parameters, providing and forecasting all of these parameters always are not available. Most of the ti...

Increased urbanization has resulted in water quality and flooding problems for many receiving waters in the United States. Bioretention, or rain gardens, is one of the most widely popular and effective best management practices in low impact development (LID), which strives to return a watershed to a predevelopment hydrologic regime. Many studies have evaluated large bioretention cells in resea...
