On 19 January 2017 in Rome With water scarcity and food demand, it is the time to stop treating the wastewater as garbage and it can be used to grow the crop and help us in water scarcity in agriculture. Waste water can be used to support for production of crop directly for the irrigation or indirectly by the recharging the aquifers but doing that might causes health risk through appropriate use or adequate treatment.
Let’s see how countries approaching this challenge and trends in the usage of wastewater in production of agriculture will be discussed by group of experts today during annual Global Forum for Food and Agriculture (19-21 January) in Berlin.
“Even though there is lacking in some detailed data, we can tell that, in global only small amount of treated wastewater is used in agriculture but most of it municipal wastewater. In some country have shown the possibilities of wrestle with mounting water scarcity”, which was stated by the senior officer Marlos De Souza with Water Division and FAO’s Land.
Wastewater which is untreated contains pathogens and microbes, antibiotic residues, chemical pollution, and other threats for health of farmers, consumer and food chain workers and it also poses the environment concerns.
There are number of approaches and technology that can being utilized around the globe to manage, treat and use wastewater in agriculture, many people are specific to local natural resources, the system of farming which are being used and corps which are being produced.
In Jordan, the reclaimed water represents the impressive of 25 percent in the total water that is used in the country. The United State, managed and treatment aquifer recharge is the common practice, mainly in the west part.
Before helping undertake the water scarcity problem, supporting the food production, reducing environmental contamination, infrastructure and management systems for reclaiming, re-using wastewater can be job creators and treating according to De Souza.
An alternative source of a critical resource
Water is the fundamental source for food production and there is growing scarcity for this important resource because of the more intense in the climate change has become significant for humanity to feed itself.
Globally, the economic expansion and population growth are increasing the pressure on fresh water with the ground water withdrawals increased by 1% per year from the year 1980.
By now, the agriculture accounts 70% of global fresh water withdrawal which is the demand for food established to grow at least 50% by 2050.
In count to serving cope with water scarcity, wastewater frequently became the high nutrient load by making it as good fertilizer. “If we use safely and managed then we can avoid environment and health risk, wastewater burden can be converted to asset”.
