How does agriculture affect amount of precipitation

image

Precipitation, especially rain, has a dramatic effect on agriculture. All plants need at least some water to survive, therefore rain (being the most effective means of watering) is important to agriculture. While a regular rain pattern is usually vital to healthy plants, too much or too little rainfall can be harmful, even devastating to crops.

What is the relationship between rainfall and agriculture?

And one of the most important parameters of climate is rainfall. Just as there is a direct relationship between climate and agriculture, so is there one between rainfall and agriculture. So when rainfall patterns change, its effect is directly felt on cropping patterns worldwide.

What is the effect of vegetation on precipitation?

By increasing the quantity of water influence on precipitation. Vegetation not only increase the number of water vapors also there cooling effects decreased the temperature of the hot air and help in the condensation of these water vapors and formation of precipitation

How do rainfall patterns affect cropping patterns?

So when rainfall patterns change, its effect is directly felt on cropping patterns worldwide. Again, as a result of depletion of the ozone layer, there will be more heat trapping gases in the atmosphere, which, according to climate models, will shift rainfall/precipitation patterns in two major ways.

Does rainfall increase or decrease in other places?

In other places, rainfall will decrease. 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.

How does more precipitation affect agriculture?

Intense rain events can physically damage crops, delay planting and harvesting, restrict root growth, and cause oxygen deficiency and nutrient loss. Between 1989 and 2016, excessive rainfall caused $10 billion in agricultural losses.


What is the relationship between rainfall and agriculture?

An important aspect to be understood regarding the relationship between rainfall and agriculture is that rainfall is the major factor in the growth and production of food crops both at the germination and fruit development stage.


Why is precipitation important to agriculture?

Agricultural production depends on weather. Rainfall can either encourage growth or dev- astate crops. Cool temperatures and springtime rains can hinder planting and seed growth, just as hot temperatures and drought can adversely stunt growth or kill mature plants later in the growing season.


How does agriculture affect water?

Excessive irrigation can affect water quality by causing erosion, transporting nutrients, pesticides, and heavy metals, or decreasing the amount of water that flows naturally in streams and rivers.


What is rainfall distribution in agriculture?

Rainfall distribution is another factor that has a direct effect on the growth of crops, it can simply be defined as the way rainfall is received through a given rainy season in an area.


What is the relationship between yield of crop and rainfall?

The main influence on grain yields is precipitation. In all months there are negative correlations between grain yield and rainfall. A weak positive correlation is found between precipitation and straw yield from April to June (stem elongation) whereas in the other months the correlation coefficients remain negative.


How does vegetation affect precipitation?

Using a new approach, researchers found that feedbacks between the atmosphere and vegetation can explain up to 30 percent of variability in precipitation and surface radiation. The paper, published today in Nature Geoscience, is the first to look at such interactions using purely observational data.


What factors affect rainfall?

Factors controlling the distribution of rainfall over the earth’s surface are the belts of converging-ascending air flow (see doldrums; polar front), air temperature, moisture-bearing winds, ocean currents, distance inland from the coast, and mountain ranges.


How does precipitation affect soil?

Changes in precipitation affect vegetation which has impacts on soil organic matter cycle and the texture of soil. This can influence the runoff rate and formation of surface crusts, which affect erosion and cause deterioration.


How can agriculture affect water shortage?

Agriculture is both a major cause and casualty of water scarcity. Farming accounts for almost 70 percent of all water withdrawals, and up to 95 percent in some developing countries. We will have to use our natural resources more wisely as time goes on and when it comes to water there is no exception.


How does agriculture affect water here on Earth?

Agricultural contaminants can impair the quality of surface water and groundwater. Fertilizers and pesticides don’t remain stationary on the landscape where they are applied; runoff and infiltration transport these contaminants into local streams, rives, and groundwater.


How can agriculture reduce water usage?

10 Ways Farmers Are Saving WaterDrip Irrigation. Drip irrigation systems deliver water directly to a plant’s roots, reducing the evaporation that happens with spray watering systems. … Capturing and Storing Water. … Irrigation Scheduling. … Drought-Tolerant Crops. … Dry Farming. … Rotational Grazing. … Compost and Mulch. … Cover Crops.More items…•


What is the relationship between weather and agriculture?

Weather is the prime uncertain factor that dictates crop growth and development in agriculture. Having forecasts means, in advance, you have with you the information on the weather (rainfall, temperature, relative humidity, atmospheric pressure, wind, dew, etc.) that is going to affect your crop in the coming days.


What is the relationship between weather climate and agriculture?

Climate change affects agriculture in a number of ways; including through changes in average temperatures; rainfall and climate extremes with an important impact on soil erosion (i.e. floods, drought, etc): changes in pests and diseases, changes in atmospheric carbon dioxide, changes in the nutritional quality of some …


What is the relationship between agriculture and environment?

While negative impacts are serious, and can include pollution and degradation of soil, water, and air, agriculture can also positively impact the environment, for instance by trapping greenhouse gases within crops and soils, or mitigating flood risks through the adoption of certain farming practices.


What is the relationship of agricultural activities with the weather?

Weather plays a major role in determining the success of agricultural pursuits. Most field crops are dependent solely upon weather to provide life‐sustaining water and energy. Livestock are also dependent upon weather for their comfort and food supplies.


How does rainfall affect food production?

So how are these predicted changes in rainfall patterns going to affect food production? An important aspect to be understood regarding the relationship between rainfall and agriculture is that rainfall is the major factor in the growth and production of food crops both at the germination and fruit development stage. But with a change in the world’s climate, temperatures will rise and rainfall will increase in some places. In other places, rainfall will decrease. 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. Farmers are already finding it difficult to cope with these environmental changes, as almost all crops are season-dependent and rainfall-dependent. Temperature and rainfall changes induced by climate change are likely to further react with other parameters of plant growth like atmospheric gases, fertilizers, insects, plant pathogens, weeds, and the soil’s organic matter. This again is expected to produce unanticipated responses.


Why is rainfall changing?

Why and how are rainfall patterns changing? As a result of global warming, the world’s climate is changing and its effect is being felt the world over. And one of the most important parameters of climate is rainfall. Just as there is a direct relationship between climate and agriculture, so is there one between rainfall and agriculture.


What are the problems associated with irrigation?

Salinization and waterlogging of soil are other serious problems associated with irrigation. In this new scenario, the management of water resources should fall in the core of all adaptation strategies. Where there is no threat of water scarcity, demand would not increase.


What crop was cut in 2016?

In India too, following a poor monsoon, the area of wheat crop was cut. However, its effect is much less than in Southern Africa because India holds enormous volumes of wheat and rice stocks.


Why do farmers in the Philippines spread their unhusked grains on concrete streets to dry in the sun?

Many farmers in the Philippines lack post-harvest storage and drying facilities and spread their unhusked grains on concrete streets to dry in the sun. Due to this the grain was of poorer quality and fetched lower prices . To add to it, the damage and excess rain made it impossible for them to plant the next crop.


What are the factors that affect plant growth?

Temperature and rainfall changes induced by climate change are likely to further react with other parameters of plant growth like atmospheric gases, fertilizers, insects, plant pathogens, weeds, and the soil’s organic matter. This again is expected to produce unanticipated responses.


How can water be stored efficiently?

This water can be stored efficiently through check dams, bunds, ponds and reservoirs. It will help irrigation in the surrounding areas and increase crop production.


How does land use affect climate?

Land use changes can also significantly contribute to climate change. Large scale changes such as deforestation, soil erosion or machine-intensive farming methods may all contribute to increased carbon concentrations in the atmosphere.


How much carbon has been lost from the biosphere in the last 300 years?

A more frequently quoted figure is that 200 to 250 Gt of carbon have been lost from the biosphere as a whole in the last 300 years. Whatever the correct figure, these reductions of ‘living carbon potential’ have resulted from. Land use changes can also significantly contribute to climate change.


How to model the effects of rainfall and water supply on agricultural productivity and income?

Generally researchers follow one of the two main approaches to model the effects of changes in rainfall and water supply on agricultural productivity and income: econometrics and mathematical programming. The first approach relies on cross-section or panel data econometric estimation of production functions, or Ricardian land price, profit and crop yield equations. Besides the usual production and crop output and input price data, researchers that follow this approach may complement their datasets with information on rainfall and temperature from gridded data, satellite data and reanalysis data, Dell et al (2014). Some examples of this approach are Kaiser et al (1993), Adams et al (1995), Deschênes and Greenstone (2007), Schlenker and Lobell (2010), Hidalgo et al. (2010), Welch and Vincent (2010), Fisher et al (2012), Wang et al. (2016) and Olayide et al. (2016).


How does water affect agriculture?

Water is a key input to agricultural production and therefore fluctuations in water availability may impact agricultural productivity and revenue. Climate science tells us that most of these fluctuations are increasingly resulting from intra-year, instead of interyearly, shifts in the timing and intensity of rainfall. Consequently predictions of the economic effects of these fluctuations would likely differ depending on how these shifts are taken into account by the empirical models. To investigate this, the present paper introduces a novel hydro-economic model in which the timing and intensity of rainfall affect the productivity of a partially irrigated agricultural system in Brazil. The specification of the production function is designed to reflect intra-year, in a monthly or seasonal basis, and interyearly shifts on rainfall to show how the opportunity cost of supplementary irrigation supply varies with changes in the timing and intensity of rainfall. Results suggest that the timing of rainfall is indeed an important economic variable and models that take into account shifts only on a yearly basis will tend to underestimate the impacts of water scarcity on agricultural income.


What’s at stake?

Climate change could make it too hot to grow certain crops, and droughts caused by climate change could reduce the amount of water available for irrigation. Climate change is also likely to cause stronger storms and more floods, which can damage crops.
