Integrated Health Risk Management for Urban and Peri-Urban Wastewater Irrigation - (4/5) Household and Epidemiological data, 2013

Worldwide about 2 million hectares of agricultural fields are irrigated with wastewater. The practice of wastewater use is particularly pronounced in the urban and peri-urban areas of developing and emerging economies. Wastewater use in urban agriculture can serve as a common denominator for the transmission of diarrhoeal, helminth and malaria diseases if not undertaken in a safe manner. This project aims to assess the contribution of informal urban wastewater irrigation to both pathogenic and mosquito vector related disease risks. The specific objectives were: 1. To assess if there is any relationship between irrigation water quality (including pathogens) and mosquito vector population density in wastewater irrigated fields; 2. To identify informal wastewater irrigation practices associated with increased risk of diarrhoeal, helminths and malaria disease risks; 3.To estimate the fraction of diarrhoeal, helminths and malaria risks attributable to urban wastewater irrigation. To address these objectives, a multidiciplinary study involving entomology, microbial and physico-chemical analysis, socio-demographic surveys, epidemiological surveys and quantitative microbial risk assessment was undertaken. All investigations were carried out in the Kumasi Metropolitan Area, Ghana. The project is divided into five parts. This dataset includes data from "Integrated Health Risk Management for Urban and Peri-Urban Wastewater Irrigation - (4/5) Household and Epidemiological data, 2013".

全球范围内约有200万公顷农田采用废水进行灌溉。废水灌溉的实践在发展中与新兴经济体的城市及城市周边区域尤为普遍。若未以安全合规的方式开展，城市农业中的废水灌溉将成为腹泻病、蠕虫病与疟疾传播的共同途径。本项目旨在评估非正规城市废水灌溉对致病原相关疾病及蚊媒传播疾病风险的贡献。具体研究目标如下：1. 评估废水灌溉农田的灌溉水质（含致病原）与蚊媒种群密度是否存在关联；2. 识别与腹泻病、蠕虫病及疟疾风险升高相关的非正规废水灌溉操作模式；3. 估算城市废水灌溉所致腹泻病、蠕虫病及疟疾风险的占比。为达成上述目标，本研究开展了多学科综合调研，涵盖昆虫学、微生物与理化分析、社会人口学调查、流行病学调查及定量微生物风险评估。所有研究工作均在加纳库马西都会区完成。本项目共分为五个部分，本数据集源自"城市及城郊废水灌溉综合健康风险管理——(4/5)家庭与流行病学数据，2013年"。
