HIGHLIGHTS

  • Indus river basin irrigation system plays a vital role in Sindh and Baluchistan of Pakistan.
  • The only cultivable command area is 5.43 Mha in Sindh and Baluchistan which depends on
  • The excess of silt (in the right bank canal of Sukkur barrage) reduces the velocity of water.
  • About 60% less cultivation was observed at Saifullah Magsi Branch Division (border of Sindh-Balochistan).
  • The satellite image based model shows the negligible velocity to the right pocket of Sukkur barrage.

ABSTRACT

Indus river basin irrigation system in Pakistan has three major reservoirs, sixteen barrages, two head works, two siphons across major rivers, twelve inter river link canals and forty four irrigation canals. Average gradient was observed from sea level as flat with rate of 12.5 cm/km (8 inches/mile). Indus provides irrigation water to major portion of Sindh (about 41 %). The total gross commanded area of Sindh and Baluchistan which depends on Indus is 5.92 Mha whereas, the only cultivable command area is 5.43 Mha. The major crops grown in Sindh are rice in Kharif and wheat in Rabi. Besides this, Sindh also produces horticultural crops such as mangoes, bananas, dates and chilies. Sindh has also diversion capacity of 111 billion cubic meter (BCM) which is equivalent to 90 million acre feet (MAF). It was found in the research that excess of silt (in the right bank canal of Sukkur barrage) reduces the velocity of water. About 60% less cultivation was observed in 2018 at Saifullah Magsi Branch Division in the border of Sindh-Balochistan. The satellite image based model shows the negligible velocity to the right pocket of Sukkur barrage.

Nanoparticles for photocatalytic removal and control of antibiotics, antibiotic resistance and resistant gene transfer

Nanoparticles for photocatalytic removal and control of antibiotics, antibiotic resistance and resistant gene transfer

C. Burak Özkal1, M. Brienza2, S. Meriç1, *

HIGHLIGHTS

  • Antibiotics degradation and control of antibiotic resistant bacteria by photocatalysis are studied.
  • Numbers of larger scale applications in real wastewater samples have to be increased.
  • Use of proper terminology and accurate units of treatment efficiency is essential.
  • In-depth research is necessary in the fields of antibiotics, antibiotic resistant treatment and antibiotic resistance genes control.

ABSTRACT

This study presents the trends and fundamentals in removal and control of antibiotics, antibiotic resistant bacteria (ARB) and antibiotics resistance genes (ARG) by nanoparticle based photocatalytic applications. A brief description on the effect mechanisms of nanoparticles for antimicrobial control is given. Examples on some of antibiotics versus the related ARB and ARG are provided. The recent literature is revised and a recommendatory conclusion on the usage of proper terminology and expression of the scientific findings in the field of ARG and ARB control is given as well.

Recycled water use for irrigation in arid region

Recycled water use for irrigation in arid region

Muhammad Muhitur Rahman

Wealthy nations in arid regions thrive to make their cities green. One of the main constraints of such initiative is sufficient supply of water due to limited reserve of groundwater. The scarcity of water in these countries is tackled by using costly desalinated water. One such nation is Saudi Arabia, where a large portion of water is supplied by costly desalinated water for drinking as well as other purposes. For irrigation purpose, sometimes desalinated water is used after shandying with ground water in urban areas; in rural areas, groundwater is used. Recycled water is used only in some big cities for urban open space irrigation and in some oasis cities (e.g. Al-Ahsa Oasis, Eastern Province) for irrigating date palm trees, to some extent. Since 1980, Al-Ahsa Irrigation and Drainage Authority, now under Saudi Irrigation Organization, supplying irrigation water to farmers as mix of groundwater, agricultural drainage water and recycled water to irrigate date palm trees. It is noticed that although other part of the world and even some of the Gulf countries have made significant progress in using the recycled water in urban irrigation and agriculture, in Saudi Arabia such initiatives are not widely visible. This hampers the Kingdom’s quest for sustainable solutions to meeting water demands while preserving environmental sustainability…
