Water use, food security and disease – achieving healthy outcomes

Tuesday 28 August | 09.00-10.30 | Room: M5
Jo Lines

The relationship between water use and human health has a long history, achieving particular success in public health interventions in water, sanitation and hygiene (WASH). However, the 21st century has seen a dramatic change in water use for improved food security and nutrition in the face of population growth. Directing natural and newly developed water resources into rapidly growing programmes of agricultural intensification is creating new interactions between water, food, nutrition and disease. For instance, rural dam building and irrigation schemes in Africa are increasing malaria risks in regions targeted for malaria elimination, while redirection of wastewater into vegetable and livestock production is creating new disease risks in dense urban populations. An unprecedented collaboration between environmental, agricultural, social and medical research is needed to understand how to improve water’s contribution to food and nutrition security without increasing disease risk. This event will examine this new interdisciplinary challenge and take as a case study the interaction between increasing water use for agriculture and the elimination of malaria and related diseases

Gold standard events are committed to ensure the gender balance in speakers/panellists and young professional representation in the session.
