"Both food security and agriculture contribute to global climate change and are affected by it. The IPCC reported that food production systems contribute up to 37% of greenhouse gas emissions associated with climate change. Similarly, food production systems are vulnerable to the negative effects of climate change. Increased extreme weather events such as rising air temperatures, flooding, drought, salinity; land degradation; and the geographical redistribution of weeds, pests and diseases pose serious food security threats in the South Asian countries. The threat caused to agriculture and food security by accelerated climate change is exacerbated by the pressure of increased population growth. Globally, more than 820 million people do not have enough food to support public health. By 2050, global food security needs to be doubled, which will make existing farming practices increasingly dependent on more reactive chemicals, water, and energy inputs (Islam 2018). Such an intensification of farming under climate change will have consequences that are expected to be detrimental to agroecosystem services, and more difficult to predict. Yet the South Asian region has a higher population growth, is also more vulnerable to the negative effects of climate changespecifically, to flooding, salinity, droughts, and solar dimming. Rising sea levels and coastal erosion could lead to a loss of 17% of land surface and 30% of food production by 2050. Agriculture and food systems must undergo innovative transformations in order to meet the challenges of food security and climate change. It is critical that a comprehensive Climate Change Adaption Framework is needed for favorable policy environment, exchange of information on climate change impacts, and adaptation of climate-smart agriculture to improve food security for the South Asia region. The book, based on the outcomes of the International Conference on Climate Change and Food Security in South Asia-2022, addresses key challenges and innovative solutions for mitigating and adapting to the impact of climate change on food security"-- Provided by publisher.
Both food security and agriculture contribute to, and are affected by, global climate change. The Intergovernmental Panel on Climate Change reports that food production systems account for up to 37% of global greenhouse gas emissions. At the same time, these systems are increasingly vulnerable to climate change, with extreme weather events such as rising temperatures, flooding, drought, secondary salinity, and land degradation threatening food security in South Asia. Additionally, the spread of weeds, pests, and diseases due to shifting climates exacerbates these challenges. The strain on agriculture and food security from accelerated climate change is further worsening by rapid population growth. Globally, more than 820 million people suffer from hunger, and by 2050, food production will need to double to meet global demands. This intensification of farming, combined with climate change, will lead to greater reliance on reactive chemicals, water, and energy inputs—potentially damaging agroecosystem services and becoming increasingly difficult to manage. South Asia, with its high population growth, is particularly vulnerable to climate impacts such as flooding, salinity, droughts, and solar dimming. Rising sea levels and coastal erosion could result in the loss of 17% of land surface and 30% of food production by 2050.
Agriculture and food systems must undergo innovative transformations to address these challenges. A comprehensive Climate Change Adaption Framework is essential for fostering a supportive policy environment, sharing information on climate impacts, and adapting climate-smart agriculture to enhance food security in South Asia. This book, based on the outcomes of the 2022 International Conference on Climate Change and Food security in South Asia, held in Dhaka, Bangladesh, explores key challenges and innovative solutions for mitigating and adapting to the impact of climate change on food security.
This comprehensive book provides insights into climate challenges in agriculture, covering key topics such as climate variability, abiotic and biotic stresses, advanced farming practices, breeding and genetics, nutrient recycling, and soil and wetlands management.
