Business Consulting for Environmental Monitoring-myassignmenthelp

Question: Discuss about theBusiness Consulting for Environmental Monitoring. Answer: In India, the use of human waste for horticulture is found in states like Gujarat, Kerala, Tamil Nadu and Delhi. Hundreds of farmers use human waste for decades particularly in farming areas where the soil has poor quality and requires enrichment. Human waste is rich in phosphorus, nitrogen and other nutrients. Farmers can use it for fertile land as well for personal farming benefits or on large scale with governments permission (Muralidharan 2017). The process involves safely converting the human waste including faecal material and urine into compost. Human waste can be recycled via thermophillic composting to convert it into organic fertiliser also known as biosolids to spread on agricultural fields and flower beds. The end product of the recycled waste does not contain any dangerous bacteria or heavy metals. This organic fertiliser can increase the agricultural yield by making the soil fertile. The application was found to have positive results on horticulture crops. There is literature evidence showing short term or long term health effects of biosolids land application. However, the negative aspects of human waste used as fertilisers include risk of organic chemicals, pathogens, toxic metals (Zinc, Arsenic, Copper etc.), and chemical irritants. However, there is a lack of well studied evidence on effects of interaction of these harmful components, their building up in soils, uptake into crops, food system and flowers, or le aching into waterways. The problem worldwide is the antibiotic resistant bacteria (Lamb et al. 2012). The socio-cultural barriers of using the human waste as fertilisers in horticulture are the poor social acceptance and adoption of the composting of human excreta. The reason may be fear of consuming phytotoxic substances. It is due to consideration of human waste as a taboo in many Indian cultures and using it for horticulture is socially unacceptable for many Indians. It may or may not be related to pathogen avoidance (Rahman and Chariar 2015). Indian states like Karnataka, Chennai, Manipur and places near Mangalore contain barren lands. Most barren lands are found near mountains or hill slopes and in southern part of India. The oddoor farms in these places are eligible for use of human waste in fertilizers. Use of human waste as fertiliser in woodlands was found to improve the water holding capacity of soil. Farmers privately use for their personal farm or on large scale with governments permission or use WHOs guidelines . Humanaure can be used by mixing the composted human faeces with pit humus via composting toilets. It may be produced passively underground at ambienttemperatures. For barren soils vermicompost is mixed with soil and spread around 2 to 3 mm thick makes the soil fertile (Bai et al. 2012). The pros and cons of using the human waste as fertiliser in woodlands are same as its use in normal horticultural fields. Poor social acceptance due to low health literacy in rural areas is the common barrier. The reason may be fear of consuming phytotoxic substances. It is due to consideration of human waste as a taboo in many Indian cultures. Pit humus and compost are considered as an inoffensive earth like products. Instead, human waste may be regarded as impure substance to be used on ancestral land, which is considered sacred. Chemical fertilisers are more preferred for woodlands as the use of organic fertiliser may take years for maturation (Rahman and Chariar 2015).
