The objective of this study was to detect the historical dry matter yield (DMY) trend and to evaluate the effects of heavy rainfall events on the observed DMY trend of whole crop maize (WCM, Zea mays L.) using time-series analysis in Suwon, Republic of Korea. Crop production in the Fanteakwa District is predominantly rainfed, exposing this major livelihood activity to the variability or change in rainfall pattern. Excessively wet conditions can negatively affect crop production in other ways. Climate change is likely to contribute substantially to food insecurity in the future, by increasing food prices, and reducing food production. Rainfall is also a good indicator of predicting common crop disease, as it can affect the spread of disease. Rainfall is needed to continue growth and to encourage yield in more advanced fall seeded winter wheat and fall rye. Besides disease, rainfall can also determine how fast a crop will grow from seed, including when it will be ready for harvesting. Kim, M.; Chemere, B.; Sung, K. Effect of Heavy Rainfall Events on the Dry Matter Yield Trend of Whole Crop Maize (Zea mays L.). Various studies have already been conducted to examine rainfall … While a regular rain pattern is usually vital to healthy crops, too much or too little rainfall can be harmful, even devastating to crops. If the average rainfall is much lower or higher than the ideal, it can lead to significant problems, from drowned crops to lower yields. Farmers are already finding it difficult to cope with these environmental changes, as almost all crops are season-dependent and rainfall-dependent. Micro-nutrients, such as Cu and Zn are widespread. Inconsistency in climate regimes of rainfall and temperature is a source of biotic and abiotic stresses in agricultural systems worldwide. Underwatering “starves” the plant of water, which can lead to crop death or low yield. State three effects of rainfall to agriculture . Water required for food production may become more scarce due to increased crop water use and drought. The industrial farm’s heavy reliance on fertilizers and pesticides may become even more costly to struggling farmers as climate impacts accelerate soil erosion and increase pest problems. Agricultural production is the product of yield (t/ha) and area harvested (ha), i.e. In 1964 Beck’s planted their first ever Practical Farm Research (PFR)® Plot. Agriculture and climate change have a reciprocal relationship. The environmental impact of agriculture varies based on the wide variety of agricultural practices employed around the world. The bars on the graphs show average precipitation differences by decade for 1901-2012 (relative to the 1901-1960 average) for each region. Extended lack of rain has devastating effects, as evidenced by the dust bowl during the Great Depression, a seven year drought from 1931 to 1938 occurring over the Great Plains region of the United States. The objective of this study was to detect the historical dry matter yield (DMY) trend and to evaluate the effects of heavy rainfall events on the observed DMY trend of whole crop maize (WCM, Zea mays L.) using time-series analysis in Suwon, Republic of Korea. Rain may inconvenience some people, but it is the lifeblood of necessary plants. soils. Matthew Cappucci, it's not only heatwaves and warmer temperatures that affect agriculture. You seem to have javascript disabled. Nationwide, reductions to agricultural productivity or sudden losses of crops or livestock will likely have ripple effects, including increased food prices and greater food insecurity. Climate change affects agricultural production through precipitation levels and temperature variations. January 2017; DOI: 10.1016/B978-0-444-63661-4.00002-5. Climate change and agriculture are interrelated processes, both of which take place on a global scale, with the adverse effects of climate change affecting agriculture both directly and indirectly. The statements, opinions and data contained in the journals are solely Pasture/hayland also need rain for re-growth and to feed livestock. Learn more about how IoT sensors can monitor weather conditions. The consequences of soil erosion are primarily centered on reduced agricultural productivity as well as soil quality. Food may become more expensive as climate change mitigation efforts increase energy prices. Centre for Environmental Economics and Policy in Africa, Policy Note no. Both of these processes take place globally, and while climate change does affect agriculture negatively, through higher temperatures and carbon dioxide levels, it is much more interesting to take a look at how agriculture affects climate change. Agriculture and climate change are deeply intertwined. The right amount of rainfall can balance out these factors, which can lead to healthier, larger crops that can be harvested more fully. "Effect of Heavy Rainfall Events on the Dry Matter Yield Trend of Whole Crop Maize (Zea mays L.)" Agriculture 9, no. The net potential effect of severe changes in rainfall pattern is the disruption in crop production leading to food insecurity, joblessness, and poverty. Please note that many of the page functionalities won't work as expected without javascript enabled. This could affect its yield or cause the entire field to become unusable. Reciprocal effects of the measures: The measures for binding heavy rainfall also have positive effects on the environment. Heavy rainfall effects. Author to whom correspondence should be addressed. In return, poor agricultural practices increase climate change. The statements, opinions and data contained in the journal, © 1996-2021 MDPI (Basel, Switzerland) unless otherwise stated. Water availability can make a pronounced difference to agricultural output and standard of living. Precipitation, especially rain, has a dramatic effect on agriculture. et al. Some climate models project a decrease in moderate rainfall, and an increase in the length of dry periods, which offsets the increased precipitation falling during heavy events. We need to eat. Plants need varying amounts of rainfall to survive. Simply put, vegetation needs water to survive. Find support for a specific problem on the support section of our website. While a regular rain pattern is usually vital to healthy plants, too much or too little rainfall can be harmful, even devastating to crops. Heavy rains also leach nutrients from hay fields. To understand the quantitative effect of heavy rain on nitrogen and phosphorus pollution in river-net plain, daily observations of nutrient concentrations in two rivers, flowing into Lake Taihu, were conducted from 1 st September, 2017 to 31 st August, 2019.
