What happened
Under UN Security Council resolution 598 (1987), paragraph 7, the UN Secretary-General sent a team of experts to study Iran's reconstruction needs after the 1980–88 war. The team made an exploratory visit in May/June 1991 (first report S/22863) and a second and final visit from 7 November to 1 December 1991, led by Abdulrahim A. Farah, a former Under-Secretary-General. Its report was transmitted on 24 December 1991 as document S/23322.
The team recorded that along the Karun River "overall economic activities have been severely constrained owing to pollution and contamination" and that farmlands "were reported to contain dangerous substances resulting from many years of war activities". It recorded "more than 250 kilometres of beaches covered with tar or asphalt" between Abadan and the Strait of Hormuz, attributed to leaking oil tankers attacked during the conflict, with mangroves and seagrass destroyed and the prawn fishery threatened. Sunken ships and wrecks in the Shatt al-Arab were described as "another serious environmental hazard", with "no records. available on the nature of cargo carried by the ships".
On land, S/23322 recorded minefields and unexploded ordnance in border areas; the Ministry of Health claimed "at least 10 persons are either killed, maimed or wounded daily". In agriculture, "more than 3 million date palms and 5,000 ha of orchards were destroyed", of which about 15 to 20 per cent had been replanted. The team could not ascertain progress on rehabilitating "some 130,000 ha of natural forests and 753,000 ha of pasture lands in the war zone" "owing to unavailability of data". It recorded loss of soil fertility from topsoil removal, compaction and flooding, waterlogging and salinity, and, as reported by the Government, "soil and water contamination. from the toxic materials emanating from chemical and biological weapons".
Iran's government assessment of non-military war damage at 1988 replacement costs was Rls 12,994,040 million for items of domestic origin, converted at Rls 237 per dollar to USD 54,827 million, plus USD 42,421 million for imported items, a total of USD 97,248 million. Iran's Environmental Protection Organization asked for international help to fund studies on debris clearance in devastated cities, clearance of tar-polluted beaches, monitoring of Karun River pollution, effects on Gulf islands, conservation of seagrass and mangrove forests and water quality in the war-affected provinces; no amount was given.
Reparations demands followed later. On 18 August 2018 Anadolu Agency reported that Iranian MP Mahmoud Sadeghi said Iraq owed Iran "$1.1 trillion" for the 1980–88 and 1990–91 wars, and that Hishmatullah Fallah Bisha, head of parliament's National Security and Foreign Policy Committee, told ISNA "War compensation cannot be ignored in relations between the two countries". The article mentions no environmental harm and reports no direct Iraqi response.
