Climatic Variables and Irrigation Water Demand
ISBN: 9783659197598 / Angielski / Miękka / 2012 / 124 str. Termin realizacji zamówienia: ok. 13-18 dni roboczych. Agriculture is a key economic sector in Bangladesh and one of the main users of fresh water resources. At present, climate change is thought to be putting extra stress on agricultural productivity and hence food security because climate change may lead to changes in irrigation water requirement. Most of the studies related to the effects of climate change on irrigation water requirement have been done based only on changes of temperature and/or rainfall. Other climatic variables, such as solar radiation, humidity and wind speed, which may also affect the irrigation water requirement, were not...

Agro-Water Management Practices in Coastal Bangladesh
ISBN: 9783659239557 / Angielski / Miękka / 2012 / 116 str. Termin realizacji zamówienia: ok. 13-18 dni roboczych. Salinization has been established as the prime cause of environmental degradation in the region and there is an urgency to find out a better water management practice. Four different types of agro-water management practices (AWMPs) were selected for investigation. Major soil and water quality parameters (temperature, salinity, pH, EC, TDS, DO, HCO3-, Ca2+, Mg2+, Cl-, Na+, K+, SO42-, NO3-, etc.) during the pre- and post-boro season of 2009-10 were analyzed to calculate the mean soil and water quality change indicators (MSQI, MWQI). Besides these, management parameters, such as cropping...
