A/HRC/10/22 page 14 resulting from the closure of the border.26 Unexploded ordnance has been discovered by civilians in residential areas; property and water supplies have been contaminated by sewage spills and reports alleged further contamination by toxic remnants from munitions.31 43. At a time when international support for the reconstruction and rehabilitation of homes and neighbourhoods is urgently needed, the Special Rapporteur is deeply concerned about persisting impediments to the entry of reconstruction materials into Gaza, either through their outright prohibition or protracted administrative delays. In addition, she recalls that, according to the Palestinian Central Bureau of Statistics, destruction of infrastructure and houses resulted in the waste of approximately $1.9 billion in international aid dollars given by donors and the international community. 44. The recent attacks have worsened the living conditions of the people of Gaza, who have been confined for decades to a small territory, in overcrowded conditions, with poor housing and sanitation conditions. Problems that have been poorly managed to date. The Special Rapporteur is particularly concerned that the scale of destruction bringing further destitution and the hardship endured by the people of Gaza will only add to the cycle of violence. C. Special Rapporteur on the right to food 45. The right to food is realized when every man, woman and child has physical and economic access at all times to adequate food or the means for its procurement. This right is violated on a large scale, and on a routine basis, in the Gaza Strip, owing to both recent events and long-standing trends. The breakdown of the food system in Gaza and the lasting damage that has been inflicted on the Gaza food production infrastructure, resulting in the loss of jobs and incomes for many families, further aggravate a situation which, even before the recent military operation of December 2008-January 2009, was intolerable. The chronic restrictions on the movements of goods and people have also had a major impact on the right to food of the people living in Gaza. 1. Destruction of property and means of subsistence 46. According to the Palestinian Centre for Human Rights and the Integrated Regional Information Network, farmland and greenhouses were bombed extensively in Gaza, which has had a devastating impact on the ability of people to produce food for subsistence or trade purposes. The Palestinian Central Bureau of Statistics estimated that 80 per cent of agricultural land and crops was damaged during the recent hostilities, as evidenced by 395 impact craters resulting from shelling.32 Arable land has been contaminated by spills of sewage and toxic munitions.33 The Office for the Coordination of Humanitarian Affairs reported that extensive 31 IPS “Unexploded bombs hold more deaths”, 24 January 2009. 32 UNOSAT damage assessment, 20 January. 33 The Observer, “Gaza desperately short of food after Israel destroys farmland”, 3 February 2009.
