effects of heavy rainfall on agriculture

Received: 18 March 2019 / Revised: 8 April 2019 / Accepted: 9 April 2019 / Published: 11 April 2019. Heavy rainfall can lead to numerous hazards, for example: 1. flooding, including risk to human life, damage to buildings and infrastructure, and loss of crops and livestock 2. landslides, which can threaten human life, disrupt transport and communications, and cause damage to buildings and infrastructure. Rainfall has shifted with an increasing trend during monsoon and almost static during other seasons. In particular, rainfall patterns are predicted to change with drier conditions in the southern UK causing issues with water supply for crop growth whilst in Scotland rainfall is expected to become concentrated into short bursts of heavy rainfall. The net potential effect of severe changes in rainfall pattern is the disruption in crop production leading to food insecurity, joblessness, and poverty. Climate change has significantly affected global agriculture in the 21st century and the Intergovernmental Panel on Climate Change (IPCC) assessment report indicates that most countries will experience an increase in average temperature, more frequent heat waves, more stressed water resources, desertification, and periods of heavy precipitation , . The flood waters produced by the seasonal rainfall transported huge quantities of silt over the banks and through the low-lying delta areas. Githiari answered the question on November 6, 2017 at 14:47. "Effect of Heavy Rainfall Events on the Dry Matter Yield Trend of Whole Crop Maize (Zea mays L.)" Agriculture 9, no. The effect of climate change on agricultural system can be seen in the interaction between changes in climate variables and the stresses that result from actions taken to increase agricultural production. Where heavy rainfall occurs with high winds, risk to forestry crops is high. If it is too wet or too dry, nutrients in the soil can run off and not make it to the plants’ roots, leading to poor growth and overall health. While a regular rain pattern is usually vital to healthy plants, too much or too little rainfall can be harmful, even devastating to crops. Areas with somewhat less rainfall are mainly grasslands, which are called prairies in North America. Pasture/hayland also need rain for re-growth and to feed livestock. Sigfox-enabled sensors can help farmers better track and predict weather conditions and rainfall, thus leading to better crop health. Rice production, especially rainfed rice, is at risk due to frequent drought and decreasing DTR. Knowing when to water, as well as how much to water, is skill backed by years of experienced for farmers. Water ways may also be blocked, and it may affect water quality. Simply put, Australia is already a hot and dry country and it’s expected to generally get hotter and drier without action on climate change. Micro-nutrients, such as Cu and Zn are widespread. If the average rainfall is much lower or higher than the ideal, it can lead to significant problems, from drowned crops to lower yields. Water availability can make a pronounced difference to agricultural output and standard of living. Phosphorous (P 2 O 5) does not generally leach very much from the soil, so except in very sandy soils, it should not have been depleted by the heavy rains.

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. whole crop maize; yield trend; climatic variable; heavy rainfall event; time series analysis, Help us to further improve by taking part in this short 5 minute survey, Actual Evapotranspiration and Tree Performance of Mature Micro-Irrigated Pistachio Orchards Grown on Saline-Sodic Soils in the San Joaquin Valley of California, The Multi-Level Perspective in Research on Sustainability Transitions in Agriculture and Food Systems: A Systematic Review, https://doi.org/10.3390/agriculture9040075. Projected impact of climate change on yields of corn, wheat, soybeans and cotton by the years 2080-2099. For Although transient increases of rainfall are common, few example, Hellblom and Bjo¨rk (1999) found that seagrasses studies have examined their effects on marine seagrasses. Today we're starting with the effect of climate change on agriculture. Other than the effect of high and low rainfall on cropping patterns, it is predicted that phenomena such as coastal flooding will reduce the amount of land available for agriculture. Kim, M.; Chemere, B.; Sung, K. Effect of Heavy Rainfall Events on the Dry Matter Yield Trend of Whole Crop Maize (Zea mays L.). The effects of global warming on food supply are dire, whilst world population is increasing. It was carried out under semiarid conditions and infertile sandy soils of Zimbabwe.
