The mountains are, in general, barren due to glaciations; however, some deciduous forests have grown at the foothills and riverbanks. However, the proportion of water going to irrigated agriculture is often much higher. It is believed that farmers utilise most of the available water but with very low efficiencies leading to water stress Komakechet al. Originally, most center pivots were water-powered. Yamamoto, T. The arid region of Pakistan has peculiar types of soil due to its topography, climate, vegetation cover, parental materials, and time period of formation main factors of soil formation.
The summers are hot and moist, while the winters are cool and dry. The number of rainy days is 9. The season is usually characterized by cold weather with low mean monthly temperature, moderate rains, high humidity and pressure, low sunshine period, and gentle breeze. Other travelers use a flat rubber hose that is dragged along behind while the sprinkler platform is pulled by a cable. The pipe doubles both as water transport and as an axle for rotating all the wheels.
The moisture contents of the soil decrease from high to low altitudes that influence the crop productivity at low lands. Moreover, the groundwater is acidic and is not suitable for drinking as well as vegetation growth. It has been divided into four sections. However, it is experiencing a problem of inequitable distribution of irrigation water among farmers. The mean temperature in January as well as December reaches below the freezing point. Wetter areas have relatively good grazing patches for livestock.

The arid region has two distinct types of forests, that is, natural vegetation and the plantation forests Figure 4. A typical lawn sprinkler system will consist of one or more zones, limited in Irrigated agriculture and the environment book by the capacity of the water source.
This variation in rainfall intensity from monsoon is due to its long trajectory decreasing the moisture index of these depressions as they travel over continental areas.
The forests are mostly used for domestic purposes and browsed for camels. In addition to the regular crop water requirements, a layer of cm of water is required for flood paddy rice, the world's largest irrigated crop, for land preparation and plant protection. A landscape irrigation system may also include zones containing drip irrigation, bubblers, or other types of equipment besides sprinklers.
Wood resources come from riverine forests and trees on farmlands, much of which is used for firewood or send to Baluchistan as a mining timber. The summers are hot and moist, while the winters are cool and dry.
The primary purpose, however, is to integrate science and technology to enable improving irrigation system performance and to provide recommendations for future irrigation research. Congress, Vol. Google Scholar Walsh, J. Newer systems have drop sprinkler heads as shown in the image that follows.
Sprinklers can also be mounted on moving platforms connected to the water source by a hose. Among the Irrigated agriculture and the environment book of water in several sectors, agricultural water has been considered as a powerful factor for providing food security and providing countless opportunity for crop diversification to feed the growing population in the world Hussain et al.
Driven by rapid urbanization and growing wastewater volumes, wastewater is widely used as a low-cost alternative to conventional irrigation water: it supports livelihoods and generates Irrigated agriculture and the environment book value in urban and peri-urban agriculture despite the associated health and environmental risks.
The modest winter rainfall over northern Indo-Pakistan is associated with disturbances, which enter the area in the extreme northwest, after passing through Iraq, Iran, and Afghanistan. David B. The monsoon currents remain steady till it begins retreating toward the beginning of September.
However, because agriculture has to compete for increasingly scarce water resources with industry and municipal users see Water scarcity belowthere is often no alternative for farmers but to use water polluted with urban waste, including sewage, directly to water their crops.
The climatic Irrigated agriculture and the environment book allowing various cropping cycles in a year in large parts of Asia, Africa and Americas, make a significantly larger cropping intensity possible in these regions than in parts of Europe and Oceania, where irrigated crop growth in the winter season is little or non-existent.
The vegetation of the region is mostly Bela, with some irrigated plantation on Indus banks and roadsides. Almost million ha are under conservation agriculture worldwide.
The area receives most of the rains in winter from western disturbances with annual total rainfall below 5 inches. This is a preview of subscription content, log in to check access. Moreover, the groundwater is acidic and is not suitable for drinking as well as vegetation growth. The barren Chaghi hills increase the daytime temperature while decrease the nighttime temperature of the region due to high absorption, deflection, reflection, and releasing of solar energy.
Booker and R. Water sources[ edit ] Irrigation is underway by pump-enabled extraction directly from the Gumtiseen in the background, in ComillaBangladesh. It is further divided into the following subregions [ 12 ]. In case of a flood spatewater is diverted to normally dry river beds wadis using a network of dams, gates and channels and spread over large areas.
As the hot season progresses, the belt of highest day temperature takes over Pakistan from south to north. The mountain slopes are mostly covered by snow particularly in Ishkoman valley, while the ground and lower mountain slopes are barren.
