Recently 60 delegates from 22 Asian countries took part in a workshop organized by the United Nations in Manila to map out national adaptation plans or NAPs, which are the main vehicles of countries for climate change adaptation including accessing climate finance. This is quite significant in the wake of US President Donald Trump’s withdrawal of America from the Paris Agreement, which binds countries to fight climate change and adapt to its effects, with enhanced support to assist developing countries to do so.

Sunlight, temperature and rainfall are the main drivers of crop production; hence, agriculture is directly affected by climate change. But it should also be noted that agriculture also affects climate change as it is responsible for about one-third of greenhouse gas emissions, a major cause of global warming. About 25 percent of carbon dioxide emissions are produced by human practices, mainly deforestation, use of fossil-fuel-based fertilizers, and burning of plant materials. Likewise, most of the methane in the atmosphere comes from livestock, forest fires, irrigated rice cultivation, and waste products.

Combating climate change is one of the biggest challenges facing humanity in the 21st century. The Intergovernmental Panel on Climate Change (IPCC) foresees that throughout the century, climate change impacts will slow down economic growth, make poverty reduction more difficult, further erode food security, and prolong existing poverty traps and create new ones.
