56 Climate change has also caused the disappearance of native species in indigenous lands. A representative from an indigenous community in southern Philippines, Bae Priscilla Cariaga, reported that Gangis, a type of beetle which is a staple in their diets, has become scarce due to changes in the onset and duration of the summer season.264 Droughts and water shortage has also become a problem in indigenous lands. Agricultural yield is reduced, water and sanitation are sacrificed, and health is compromised. Further, community members, particularly the Mangyans, have tussled amongst themselves in the struggle to get water from drying springs.265 d. Older Persons The UN Principles for Older Persons recognizes the rights of older persons to adequate food, water, shelter, clothing and health care.266 It states that “older persons should be able to live in environments that are safe and adaptable to personal preferences and changing capacities.”267 Older adults are among the most vulnerable during extreme weather events, particularly when separated from their families and caregivers.268 Immobility, difficulty crossing terrain, pre-existing conditions, and declining health often lead to inadequate access to food, water, safe housing, and healthcare. In November 2020, a 78-year-old man was reported to have suffered a stroke and died as he was being evacuated during Typhoon Goni (local: Ineng). In the same month, Typhoon Vamco (local: Ulysses) claimed the lives of at least three older persons including one who died after slipping and falling to the floor, and another who was killed after a tree fell on his house due to strong winds.269 A few weeks later, during Tropical Storm Krovanh (local: Vicky) a 67-year-old woman and 62-year-old 264 Bae Priscilla Cariaga, Focus Group Discussion in Northern Mindanao, at 44. 265 Id. 266 United Nations General Assembly, United Nations Principles for Older Persons, A/RES/46/91 (Dec. 16, 1991) [hereinafter UN Principles for Older Persons]. 267 Id. 269 CNN Philippines, Typhoon Ulysses Kills at Least 13, Leaves 15 Missing, CNN Philippines, Nov. 12, 2020, available at https://www.cnnphilippines.com/news/2020/11/12/ulysses-death-toll.html (last accessed July 21, 2021). 268 ACAPS, Secondary Data Review: Philippines Typhoon Yolanda, available at https://www. humanitarianresponse.info/sites/www.humanitarianresponse.info/files/assessments/140111%20 SDR%20Yolanda%20Philippines%20final.pdf (last accessed Jan. 13, 2020) (citing United Nations Children’s Emergency Fund Philippines, Typhoon Haiyan Strategic Response Plan, 10 December 2013, available at https://reliefweb.int/sites/reliefweb.int/files/resources/Strategic%20 Response%20Plan%20-%20Philippines%2010-Dec-2013.pdf [last accessed Jan. 13, 2020]) [hereinafter ACAPS Data Review].
