The species richness of wild carnivores was highest in landscapes with a patchwork of arable fields and semi-natural habitats such as forests and shrubland, though it was also high in irrigated landscapes with dense networks of irrigation channels and tree lines bordering agricultural fields.
They are nocturnal and in temperate climates make their homes in dense vegetation along irrigation ditches and in fields.
A continuum of societies may be constructed, ranging from tiny, simple bands of hunter-gatherers in poor environments to large, dense populations of irrigation agriculturalists that is, from the entirely nomadic to the fully sedentary.
This was most likely due to limited air supply (Currie 1962) since the sieved loam provides a dense growth medium upon irrigation.
Intensive irrigation supports a dense population in the huertas on the satellite farming communities around the city of Murcia.
The effects of irrigation levels and dense corm planting on flower yield, daughter corms behavior and phosphorus uptake of saffron (Crocus sativus L). were studied as two-year field experiment based on a randomized complete blocks design arranged in split-plot with three replications at Faculty of Agriculture, Ferdowsi University of Mashhad, Iran, during 2012 2013 and 2013 2014 growing seasons.
For further precision, a farmer can use soil-moisture probes to let him know how much water each bit of a field is using, since denser, clay-based soil requires less irrigation than looser, sandy soil.The farmer, or his agent, uploads all this information into a piece of software written by one of the companies involved.
It forms dense mats that interfere with navigation, recreation, irrigation, and power generation.
Along the Awash River flood plains, dense woodland and swamps have been reclaimed for irrigation (ANRS 2010).
The oasis is cut by a dense network of old riverbeds as well as by irrigation channels and ditches beginning in neighbouring Uzbekistan.
