It is therefore no surprise that wastewater irrigation has been shown to increase agricultural yields (Singh hypertension test purchase 10mg norvasc, Deshbhratar arrhythmia signs order norvasc 5mg, and Ramteke 2012) blood pressure quitting drinking order 5mg norvasc. In 2010 heart attack with pacemaker quality norvasc 10mg, farmers in the Mezquital Valley of Mexico protested the construction of a wastewater treatment plant, fearing that removing the harmful contaminants of the water would also remove the nutrients that many believe make the region so productive. Wastewater also has the benefit of being available year-round, including during the dry season, whereas regular water irrigation is often restricted to certain parts of the year in arid regions. The benefits of wastewater irrigation can extend past the farmers-weekly market prices for cauliflower and potatoes in Pakistan were found to fall 59 and 44 percent, respectively, when local wastewater-produced varieties entered the market, merely because of the change in the ratio of supply to demand (Ensink et al. Nevertheless, if not carefully managed, wastewater irrigation can harm crop quality and cause health concerns and environmental damage. Urban wastewater is often high in concentrations of heavy metals, particularly in cities where heavy industry is present. When fields are repeatedly irrigated with this water, concentrations of heavy metals build up in the soil. This can be harmful both to crop production-reducing the yield benefits of wastewater irrigation over time-and to humans and animals who consume the metal-rich plants (Meng et al. Thus, consuming food grown from untreated wastewater irrigation may lead to slow poisoning over time. A recent study found that globally, 65 percent of all irrigated croplands within 40 kilometers downstream of urban areas rely heavily on wastewater flows, potentially exposing some 885 million urban residents to serious health risks (map 3. Untreated wastewater can also carry bacteria, viruses, and other pathogens that can infect consumers and cause acute health impacts. In Pakistan, for instance, untreated wastewater irrigation was linked to Giardia duodenalis infection from a parasite, which can cause nausea and diarrhea (Ensink, van der Hoek, and Amerasinghe 2006). Households that farmed with wastewater had significantly higher risks of infection than those that did not, and nonfarming laborers employed near areas that farmed with wastewater were at risk, likely through food transmission. In the Republic of Korea, it was found that irrigating rice with wastewater increased the likelihood of Escherichia coli infection, especially among children. The infection was transmitted not necessarily from consumption of the rice but simply from the increased environmental risks that the water poses during cultivation. These risks subsided one or two days after fields were flooded and could be greatly reduced through ultraviolet light disinfection systems (An et al. Irrigating with wastewater also has the potential to permanently contaminate groundwater supplies. However, with repeated exposure, soils will eventually reach capacity for storing these pollutants. Once groundwater supplies become exposed, particularly in the case of nutrients and heavy metals, treatment can become infeasible (Maheshwari, Singh, and Thoradeniya 2016). With agriculture responsible for 70 percent of freshwater abstractions globally, and the need for an additional 20 percent increase in water withdrawals by 2050 to feed a population of 9 billion, the problems of water scarcity often overshadow those of water quality. Nevertheless, the results in this chapter demonstrate that yield losses due to saline water may exceed those due to rainfall variability by a ratio of more than 2 to 1. One of the common methods for adapting to dwindling water supplies, wastewater irrigation, is causing significant public health concerns. Although water treatment, reverse osmosis, and other forms of water purification may suffice as solutions to poor water quality for drinking water or water for industry, the economics do not work when it comes to desalinizing water for agriculture. Energy costs of desalination are simply too high to economically justify its use for nearly all forms of agriculture, where value per drop of water is low (box 3. Therefore, the focus must be on prevention of, or adaptation to , brackish or contaminated waters. Preventing irrigated waters from becoming too saline is a matter of maintaining a steady salt balance, particularly in the root zone of the soil where crops are particularly sensitive. Salt is a naturally occurring mineral, and regardless of the source of water, low-level concentrations of dissolved salts are inevitable. Maintaining a proper salt balance therefore requires that the same amount of salt that flows into a field also flows out.

However arrhythmia beta blockers norvasc 5 mg, there are political and environmental win-wins in which these highly inefficient subsidies (in many countries hypertension 1 norvasc 10 mg, excess nitrogen fertilizers are counterproductive and reduce yields) can be replaced with less distorting subsidies or income support programs blood pressure lisinopril 10mg norvasc, thus ensuring that nobody is made worse off heart attack in sleep generic 10 mg norvasc. Payments for ecosystem service schemes are one such example, whereby farmers can be paid to use less fertilizer. Another way of controlling nutrient pollution from nonpoint sources like farms is through pollution trading. Nitrogen fertilizer consumption 100 million 80 million 60 million 40 million Europe 20 million 0 1961 1970 1980 1990 2000 2010 2014 b. Note: Panels show the consumption of nitrogen fertilizer in tons across regions (panel a) and the global production of nitrogen, phosphate, and potash fertilizer (panel b) in tons per year. An N:P:K ratio of 4:2:1 is generally considered an acceptable benchmark of fertilizer mix. While the correct proportions are driven by the type of crop, soil, and other agronomic conditions, measuring deviations from the recommended ratio can reveal the extent of distortion. In many of these countries, fertilizer use is disproportionately tilted toward the use of nitrogen. Oftentimes, the structure of fertilizer subsidies contributes heavily to such a skew. In India, this skew is particularly striking in favor of nitrogen, where fertilizer subsidies heavily support nitrogen over other nutrients, resulting in an inefficient balance of fertilizer application (Chatterjee and Kapur 2017; Gulati and Banerjee 2015). This is exemplified by the yawning gap between global and Indian domestic nitrogen prices-world prices were almost four times higher than regulated Indian prices in 2014 (Huang, Gulati, and Gregory 2017). As a result, application ratios in India are 8:3:1, with adverse long-term impacts on soil fertility and crop yields (Huang, Gulati, and Gregory 2017). Agents who are less productive nutrient users often find that it is more profitable to sell their pollution allocations to more productive agents than to use them. Thus, trading schemes have the potential to lead to economically efficient outcomes while also limiting total nutrients released into the environment. Multiple heterogeneous pollutants (for instance, nitrogen and phosphorus) must be tracked from multiple emission sources to multiple end points. Interactions among these pollutants can change how they impact water resources, as can external factors like weather, landscape, and anthropogenic activities (Shortle and Horan 2017). Thus, establishing the total amount of nutrients that the trading scheme should permit is difficult. Transaction costs in establishing and participating in markets, as well as complexities in calculating emissions and abatement, make monitoring and enforcement difficult. Therefore, pollution trading schemes are currently relegated to highincome countries like Canada, New Zealand, and the United States where the capacities of regulatory bodies are higher. Even still, most of these schemes have seen little pollution trading thus far (Fisher-Vanden and Olmstead 2013; Ribaudo and Gottlieb 2011) implying either overallocation of nutrient emissions or difficulty in establishing markets. Thus, more work is needed to design systems that are not simply efficient from an economic standpoint but also can manage all of these complexities while remaining feasible in developing country settings and encouraging trading between agents. Finally, an important lesson of this chapter is the impact that climate change will have on water quality. Both nitrogen and salinity in water are significantly affected by rainfall variability. With climate change expected to increase variability in most regions across the world, the impact on water quality is an important challenge that is often overshadowed by water scarcity and flooding. In addition, hotter temperatures increase biological growth when nitrogen is present, leading to more frequent and cyanobacterial and algal blooms. Some solutions already discussed will help protect water resources from the impacts of climate change. Reducing the footprint of urban areas and impervious land will prevent nutrients and salts from washing off the land and into waterways. Similarly, with less nitrogen spread on farmlands, there will be less to run into lakes and rivers. When water levels are low because of dry rainfall shocks or prolonged droughts, nutrients and salts in water are less diluted and therefore more harmful. Thus, it is important to manage water supplies to ensure water levels remain high enough to dilute expected pollutants during times or low rainfall or runoff. Infrastructure can play an important role in regulating water supplies, storing water during times of plenty and releasing it when the environment turns dry.
