How does rainfall affect agriculture?

How does rainfall affect agriculture?

Excessive rainfall can affect crop productivity in various ways, including direct physical damage, delayed planting and harvesting, restricted root growth, oxygen deficiency and nutrient loss, the researchers said.

How does rainfall affect Africa?

Increases in temperature and changes in rainfall patterns also significantly affect population health across Africa. Warmer temperatures and higher rainfall increase habitat suitability for biting insects and the transmission of vector-borne diseases such as dengue fever, malaria and yellow fever.

How has the climate affect farming in Africa?

Changes in climate such as higher temperatures and reduced water supplies, along with other factors like biodiversity loss and ecosystems degradation, affect agriculture. Therefore, if current climate trends continue, by 2030 wheat production is likely to decline by 10% to 20% from 1998–2002 yields.

What are the effects of heavy rainfall to agricultural production?

The warmer the soil and the longer it is saturated, the bigger the loss of nitrogen by denitrification. Frequent and excessive rainfall can force some farmers to delay side-dressing of nitrogen (most likely from urea).

What is the main problem in rainfed agriculture?

Rainfed Crops are prone to breaks in the monsoon during the crop growth due to water stress. This water stress may be due to variability of rainfall, delay in sowing, diversity in crop management practice and variability of the soil type. The prolonged breaks can result in partial o r complete failure of the crops.

Can rain damage crops?

Intense rain events can physically damage crops, delay planting and harvesting, restrict root growth, and cause oxygen deficiency and nutrient loss.

Why is Africa most affected by climate change?

Africa will be one of the regions most impacted by the adverse effects of climate change. Reasons for Africa’s vulnerability are diverse and include low levels of adaptive capacity, poor diffusion of technologies and information relevant to supporting adaptation, and high dependence on agro-ecosystems for livelihoods.

What can be done in Africa to counter global warming?

Solutions to global warming in Africa include effective land use planning to avoid forest degradation, developing renewable energy, and limiting the expansion of coal-fired power plants.

Which region in Africa has the best climate for agriculture?

Climate and Farming in South Africa. Crops grow best where temperature, rainfall and climate are optimal for that specific crop.

What is the effect of very little rainfall on food production?

However, a combination of not enough watering and no rainfall could also lead to dying crops. Underwatering “starves” the plant of water, which can lead to crop death or low yield. Conversely, overwatering can lead to browned tips of crop leaves and also possible root rot and other issues.

How can we protect crops from flooding?

Several mechanisms can help in this matter: Dikes and soil bunds can help protect fields from unexpected floods and they can also allow farmers to drain or retain water as needed; drainage ditches can be used to channel away excess floodwaters; and reuse agreements can enable farmers to take turns using water from the …

Which country is rank first in rainfed agriculture?

Abstract: India ranks first among the rainfed agricultural countries in the world.

What is the impact of rainfall variability on crop production?

Crop production in the Fanteakwa District is predominantly rainfed, exposing this major livelihood activity to the variability or change in rainfall pattern. The net potential effect of severe changes in rainfall pattern is the disruption in crop production leading to food insecurity, joblessness, and poverty.

How does rainfall affect food production in Ghana?

As a major concern to food production in Ghana, this study seeks to show the relationship between the production of major crops and rainfall distribution pattern in the Worobong Agroecological Area (WAA) relative to food security in the face of climate change.

What are the effects of changes in rainfall?

The net potential effect of severe changes in rainfall pattern is the disruption in crop production leading to food insecurity, joblessness, and poverty.

How is rainfall related to the production of food?

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.
