Farmers' Awareness about Impacts of Reusing Wastewater, Risk Perception and Adaptation to Climate Change in Faisalabad District, Pakistan

Water scarceness is the most critical problem for numerous arid and semi-arid areas. It leads to the use of wastewater in many countries. This study was aimed to determine the farmer's awareness about reusing wastewater in their risk perception and adaptation to climate change in district Faisalabad, Pakistan. Faisalabad has become an industrial hub and industrial discharge is becoming problematic for local community and environment. Usually, farmers depend on wastewater for agriculture purposes in many aspects. The present study was divided into two phases, in the first phase a questionnaire based study was conducted in urban and peri-urban areas while in the second phase, wastewater quality parameters were determined (pH, SS, TDS, BOD, COD, arsenic, cadmium, chromium, copper, lead, nickel and zinc) and compared with Pakistan Environmental Quality Standards. Results indicated that farmers had a strong awareness (96.8%) about fertility value of wastewater for many aspects, but they were unaware (71.6%) about health hazard of untreated wastewater used for crop irrigation. In the current study correlation of Determining of Climate Change (DCC) with age and farming experience was highly significant with correlation values 0.48 and 0.40 respectively. Adaption Measures (AM) correlation values with age and farming experience were 0.49 and 0.75 respectively. Other variables livelihood Assets (LA) was also correlated with Determining of Climate Change (DCC) and Adaption Measures (AM) and all variables were found significant week to moderate correlation among all selected variables. Farmers (>70%) used different techniques to adapt to climate change like irrigation, seeds, fertilizer and crops. Industrial and sewage wastewater quality of Faisalabad showed higher values than PEQs, creating an alarming situation for local people's health and environment. High metal pollution index (
