titling and demarcation procedures are often put on delay, or leased out by the state as concessions for extractive industries without consulting Indigenous communities. Many in the United States federal government are in favor of exploiting oil reserves in the Arctic National Wildlife Refuge, where the Gwich'in Indigenous people rely on herds of caribou. Oil drilling could destroy thousands of years of culture for the Gwich'in. On the other hand, some of the Inupiat people, from another Indigenous community in the region, favor oil drilling because they could benefit economically. The introduction of industrial agricultural technologies such as fertilizers, pesticides, and large plantation schemes have destroyed ecosystems that Indigenous communities formerly depended on, forcing resettlement. Development projects such as dam construction, pipelines and resource extraction have displaced large numbers of Indigenous peoples, often without providing compensation. Governments have forced Indigenous peoples off of their ancestral lands in the name of ecotourism and national park development. Indigenous women are especially affected by land dispossession because they must walk longer distances for water and fuel wood. These women also become economically dependent on men when they lose their livelihoods. Indigenous groups asserting their rights has most often resulted in torture, imprisonment, or death. The building of dams can hurt Indigenous peoples by hurting the ecosystems that provide them water, food. For example, the Munduruku people in the Amazon rainforest are opposing the building of Tapajós dam with the help of Greenpeace. Most Indigenous populations are already subject to the deleterious effects of climate change. Climate change has not only environmental, but also human rights and socioeconomic implications for Indigenous communities. The World Bank acknowledges climate change as an obstacle to Millennium Development Goals, notably the fight against poverty, disease, and child mortality, in addition to environmental sustainability. Use of indigenous knowledge Indigenous knowledge is considered as very important for issues linked with sustainability. Professor Martin Nakata is a pioneer in the field of bringing indigenous knowledge to mainstream academics and media through digital documentation of unique contributions by aboriginal people. The World Economic Forum supports using indigenous knowledge and giving to the indigenous peoples ownership of their land for protecting nature. Knowledge reconstruction The Western and Eastern Penan people are two major groups of Indigenous populations in Malaysia. The Eastern Penan are famous for their resistance to loggers threatening their natural resources, specifically Sago palms and various fruit bearing trees. Because of
