text: In addition to the severe health issues caused by haze from air pollution, dust storm particles, and bush fire smoke, reduction in irradiance is the most dominant impact of these sources of haze and a growing issue for photovoltaic production as the solar industry grows. Smog also lowers agricultural yield and it has been proposed that pollution controls could increase agricultural production in China. These effects are negative for both sides of agrivoltaics (the combination of photovoltaic electricity production and food from agriculture).
  International disputes
  Transboundary haze
  Haze is no longer just a confined as a domestic problem. It has become one of the causes of international disputes among neighboring countries. Haze can migrate to adjacent countries in the path of wind and thereby pollutes other countries as well, even if haze does not first manifest there. One of the most recent problems occur in Southeast Asia which largely affects the nations of Indonesia, Malaysia and Singapore. In 2013, due to forest fires in Indonesia, Kuala Lumpur and surrounding areas became shrouded in a pall of noxious fumes dispersed from Indonesia, that brings a smell of ash and coal for more than a week, in the country's worst environmental crisis since 1997.
