Climate Change Research Strategy for Primary Industries

The document discusses a study looking at ways to reduce nitrous oxide emissions from animal agriculture systems. The study focuses on emissions from urine patches in dairy grazing systems and tests the effectiveness of applying dicyandiamide (DCD) to pastures both immediately after and one month prior to applying urine from grazing animals. The results showed DCD reduced nitrous oxide emissions by 35-45% regardless of when it was applied relative to urine application. DCD's impact on emissions was found to last at least 90 days when applied in late winter or autumn. Whole paddock dry matter production was minimally affected by DCD application.

Climate change refers to a statistically significant variation in either the mean state of the climate or in its Variability, persisting for an extended period (typically decades or longer). For the past some decades, the gaseous composition of earth’s atmosphere is undergoing a significant change, largely through increased emissions from energy, industry and agriculture sectors; widespread deforestation as well as fast changes in land use and land management practices. These anthropogenic activities are resulting in an increased emission of radiatively active gases, viz. carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O), popularly known as the ‘greenhouse gases’ (GHGs) These GHGs trap the outgoing infrared radiations from the earth’s surface and thus raise the temperature of the atmosphere. The global mean annual temperature at the end of the 20th century, as a result of GHG accumulation in the atmosphere, has increased by 0.4–0.7 ºC above that recorded at the end of the 19th century. The past 50 years have shown an increasing trend in temperature @ 0.13 °C/decade, while the rise in temperature during the past one and half decades has been much higher. The Inter-Governmental Panel on Climate Change has projected the temperature increase to be between 1.1 °C and 6.4 °C by the end of the 21st Century (IPCC, 2007). The global warming is expected to lead to other regional and global changes in the climate-related parameters such as rainfall, soil moisture, and sea level. Snow cover is also reported to be gradually decreasing. Therefore, concerted efforts are required for mitigation and adaptation to reduce the vulnerability of agriculture to the adverse impacts of climate change and making it more resilient. The adaptive capacity of poor farmers is limited because of subsistence agriculture and low level of formal education. Therefore, simple, economically viable and culturally acceptable adaptation strategies have to be developed and implemented. Furthermore, the transfer of knowledge as well as access to social, economic, institutional, and technical resources need to be provided and integrated within the existing resources of farmers.

The world is running short of time and option at social and economic front in view of high risks related with global warming and climate change, which is a result of the “enhanced greenhouse effect” mainly due to human induced release of greenhouse gases (GHGs) into the atmosphere (IPCC, 2007). The GHGs inventories are going on all over the world and every possible method to control them are being recognized and evaluated. Carbon footprint is a measure of the exclusive total amount of carbon dioxide emissions that is directly and indirectly caused by an activity or is accumulated over the life stages of a product (Pandey et al., 2011). The crop production contributes significantly to global carbon emissions at different stage of crop through the production and use of farm machinery, crop protection chemicals such as herbicides, insecticides and fungicides, and fertilizer (Hillier et al., 2012). Pathak et al.(2010) calculated the carbon footprint of 24 Indian food items and reported that in the production of these food item 87% emission came from food production followed by preparation (10%), processing (2%) and transportation (1%). Maheswarappa et al. (2011) reported that the C-sustainability index (increase in C output as % of C-based input) of Indian agriculture has decreased with time (from 7 in 1960-61 to 3 in 2008-9). Agricultural uses, including both food production and consumption, contribute the most reactive nitrogen (Nr) to the global environment. Once lost to the environment, the nitrogen moves through the Earth’s atmosphere, forests, grasslands and waters causing a cascade of environmental changes that negatively impact both people and ecosystems. Leach et al. (2012) developed a tool called N-Calculator, a nitrogen footprint model that provides information on how to reduce Nr to the environment. Therefore, Quantification of GHGs from each stage of lifecycle of a product gives complete picture of its impact on global warming and provides necessary information to develop low C technology and mitigation option not only for industrial product but also for agricultural produce. The C and N footprint for a given field will allow growers, advisors and policy makers to make informed decisions about management to optimize crop production, biodiversity and carbon footprint.

The International Food Policy Research Institute (IFPRI) and the Nepal Agricultural Economics Society (NAES) are jointly organizing Annual Conference of Nepal Agricultural Economics Society on February 13-14, 2015 at Conference Hall, Trade Tower, Thapathali, Kathmandu, Nepal. During the annual conference of NAES, a special session on “Convergences of Policies and Programs relating to Sustainable and Climate Resilient Agriculture” is being organized. The aim of this special session is to showcase the studies and experiences in South Asian countries on climate resilient agriculture and how they can learn from each other to formulate progressive and sustainable policies to promote climate smart agriculture in a regional perspective.
