Rice Yields

Abstract This study investigates the relationship between rice yields, climate change, and carbon dioxide (CO2). We integrate gridded climate data in the growing seasons and Asian rice yield data reported by the Food and Agriculture Organization with free air carbon dioxide enrichment (FACE) experimental data. Using those data, we estimate prediction models of rice yields that evolve over time and decompose effects of climate, CO2, and technological progress. The results show that atmospheric CO2 has significantly increased rice yields, with the contribution accounting for 29% to 33% of the observed yield growth. The results also reveal that increases in temperature decrease rice yields in parts of Asia, implying that both CO2 mitigation and climate change are yield growth depressing factors. The finding suggests a potential need for more agricultural research and development investment to offset CO2 mitigation and climate change effects.

Globally there are concerns about outdoor air pollution and its effects on the environment and human health. Researchers are concerned with the negative effects of and best mitigation strategies for air pollution. Climate change and human health are a common phenomenon associated with air pollution, as carbon dioxide (CO2) is absorbed and emitted naturally as part of the carbon cycle. This study was aimed at assessing the emission level of CO2 in Kuje Area Council in the Federal Capital Territory, Nigeria and its effect on the environment and human health. Fifty specific residential and commercial locations were considered, and over 1200 observations of CO2 field data were collected and analysed during two seasons–dry and wet. The land-use settlement pattern was taken into consideration. The data were collected weekly at different time bands (2-, 4-, 6-, and 8-hour time intervals) using the AMPROBE CO2-100, CO2 meter gas detection instrument with self-calibration capability of ±30 parts per million (ppm), ±5% reading (0–5000) accuracy. A Garmin CX60 global positioning system was used to obtain the point locations Universal Transvers Mercator coordinates. The results showed higher mean CO2 emission values of >541 ppm and <713 ppm during the dry and wet seasons, respectively. It was also observed that these values were contrary to and exceeded the American Society of Heating, Refrigerating and Air-Conditioning Engineers and Occupational Safety and Health Administration normal outdoor level standards of 350–450 ppm. These higher CO2 values were found in the residential and commercial districts, and if not monitored and controlled they will have adverse effects on human health and climate change effects. Quick interventions would be to plant trees to sequestrate the CO2 and to regulate the transportation system within the area due to continuous carbon emission.

The Impact

The spatial and temporal particularities of Normalized Differential Vegetation Index (NDVI) changes over territory of Belarus in the current century and their relationship with climate change were investigated. The rise of NDVI is observed at approximately 84% of the Belarus area. The statistically significant growth of NDVI has exhibited at nearly 35% of the studied area (t-test at 95% confidence interval), which are mainly forests and undeveloped areas. Croplands vegetation index is largely descending. The main factor of croplands bio-productivity interannual variability is precipitation amount in vegetation period. This factor determines more than 60% of the croplands NDVI dispersion. The long-term changes of NDVI could be explained by combination of two factors: photosynthesis intensifying action of carbon dioxide and vegetation growth suppressing action of air warming with almost unchanged precipitation amount. If the observed climatic trend continues the croplands bio-productivity in many Belarus regions could be decreased at more than 20% in comparison with 2000 year. The impact of climate change on the bio-productivity of undeveloped lands is only slightly noticed on the background of its growth in conditions of rising level of carbon dioxide in the atmosphere.
