Use of Moringa oleifera seed extracts to reduce helminth egg numbers and turbidity in irrigation water por Sengupta, M.E., Keraita, Bernard N., Olsen, A., Boateng, Osei K., Thamsborg, S.M., Palsdottir, G.R., Dalsgaard, A.

“…Water from wastewater-polluted streams and dug-outs is the most commonly used water source for irrigation in urban farming in Ghana, but helminth parasite eggs in the water represent health risks when used for crop production. Conventional water treatment is expensive, requires advanced technology and often breaks down in less developed countries so low cost interventions are needed. …”

Participatory research in Ikulwe-Iganga District, Uganda por Kayuki, KC, Wortmann, Charles S.

“…Farmers are paring corms to control banana weevils, and researchers have promised a cheaper alternative to the hot water treatment with which farmers had experimented. Canavalia, Mucuna, Crotolaria, and lablab were evaluated as either green manure or improved fallow for soil fertility improvement, and for their incorporation into the farming systems. …”

How robust is water quality determination with optical measurements for highly polluted agricultural waters? por Uwera, Honorine

“…Optical technology is used to measure and monitor water quality, to date mainly in drinking water treatment, where water is typically much cleaner than in heavily polluted agricultural streams. …”

Modelling of carbamazepine and diclofenac in a river network por Vochezer, Klaus

“…In the model the pharmaceutical input is calculated on the base of yearly sales per capita, a constant yearly consumption and waste water treatment plants as point pollution sources. The model indicated that up to 28 % of the seasonal variation in Diclofenac loads could be explained by direct photolysis. …”

Wastewater treatment and reuse in urban agriculture: exploring the food, energy, water, and health nexus in Hyderabad, India por Miller-Robbie, Leslie, Ramaswami, A., Amerasinghe, Priyanie H.

“…Second, despite water cycling benefits in urban agriculture, only <1% of the nutrients are able to be captured in urban agriculture, limited by the small proportion of effluent divertible to urban agriculture due to land constraints. Thus, water treatment plus reuse in urban farms can enhance GHG mitigation and also directly save groundwater; however, very large amounts of land are needed to extract nutrients from dilute effluents. …”

Inactivation of viruses in water by chlorination using bacteriophages as model organisms por Kanna, Charan Raju

“…Swedish and Norwegian surface waters are rich in humic substances with high organic carbon content that interferes with disinfection, the most important barrier to viruses in the water treatment plant. Therefore the disinfection potential of free chlorine was evaluated for a number of viruses: canine adenovirus (CAdV), murine norovirus (MNV), mammalian orthoreovirus (MRV) and porcine enterovirus (PEV), and model viruses (MS2, 28B, ФX174 and Ф6 bacteriophages) on different water qualities (pH, turbidity and organic carbon content). …”

Protected agriculture, precision agriculture, and vertical farming: Brief reviews of issues in the literature focusing on the developing region in Asia por Takeshima, Hiroyuki, Joshi, Pramod Kumar

“…For vertical farming, research has often highlighted the variations in technologies based on out-door / indoor systems, ways to improve plants’ access to light (natural or artificial), growing medium and nutrient / water supply, advanced features like electricity generation and integration of production space into an office / residential space, and water treatment. For India, issues listed above may be some of the key areas that the country can draw on from other more advanced countries in Asia, or can focus in its adaptive research to improve the relevance and applicability of these technologies to the country.…”
