Impacts on people Economic impacts The poverty rate of Pakistan, when estimated at $2 per day purchasing power parity, exceeds 50% of the total population with stark provincial disparities. This high prevalence of poverty, coupled with the lack of and access to resources, places the country in the low human development category, ranked 146 out of 187 countries, well below the average human development index value compared to other South Asian countries. The Intergovernmental Panel on Climate Change (IPCC) Fifth Assessment Report (AR5) for the Asia region noted that the sensitivity of agriculture-dependent economies (such as Pakistan) toward climate change arises from their distinct geography, demographic trends, socioeconomic factors, and lack of adaptive capacity that when taken together, determine the climate change vulnerability profile of the country. Agriculture Future projections for Pakistan are that major crop yields such as of wheat and rice are expected to decrease significantly. According to research led by Dr. Adil Najam at the Lahore University of Management Sciences, by 2040 the cost of climate change to agriculture in Pakistan is likely to be up to 7% of productivity but that good climate adaptation practices could result in a net productivity gain of up to 40%. The 2022 Pakistan floods mainly caused by increased precipitation and glaciers melting fueled by climate change, destroyed around 50% of the crops of Pakistan what can lead to food shortages. Migration Due to extreme weather and uncertain economic outcomes, rural communities in Pakistan have been displaced in large numbers to major cities. Experts expect 20% of the population to move to major cities; current migration patterns included 700,000 people a year moving from rural to urban environments. Larger estimates, including major displacements because of extreme weather, suggest as many as 20 million migrants from rural to urban communities since 2010. Mitigation and adaptation Mitigation The most important targets for mitigation efforts focused on reduction of GHG emissions are the energy and agriculture sectors. In the energy sector, integration of climate change and energy policy objectives is particularly important as today's investment such as in the Thar coalfield will "lock in" the infrastructure, fuel and technologies to be used for decades to come. Similarly, the building and transport infrastructure put in place today should meet the design needs of the future. Therefore, energy efficiency requirements in building codes and long-term transport planning will prove important. Policies and legislation The National Climate
