How is climate change altering precipitation in Ghana?

Climate change in Ghana is projected to affect its vital water resources, energy supplies, crop production and food security. … More intense rainfall is expected to increase erosion, while less total rainfall may decrease the water flow.

How is climate change affecting Ghana?

Three major physical impacts of climate change have been identified in Ghana and these are; temperature change, change in rainfall and sea level rise [2]. Owusu et al. [3] report that there is a shift in the rainfall regime in Ghana towards a longer dry season and vanishing wet season.

How is climate change altering precipitation in general?

How is Precipitation Changing? As climate changes, several direct influences alter precipita- tion amount, intensity, frequency and type. Warming accelerates land surface drying and increases the potential incidence and severity of droughts, which has been observed in many places worldwide (Figure 1).

How does climate change affect rainfall?

As temperatures rise and the air becomes warmer, more moisture evaporates from land and water into the atmosphere. More moisture in the air generally means we can expect more rain and snow (called precipitation) and more heavy downpours.

Is Ghana vulnerable to climate change?

The economy of Ghana is highly vulnerable to climate change due to its impact on key sectors such as health, energy, agriculture, infrastructure, water resources, land, fisheries and forestry.

How does climate change result in famine?

20 But a 5°F to 9°F rise in global average temperature could reduce grain yields by 30% to 50%, and global food supplies even more. The combination of decreasing food production in the face of increasing food demand would likely lead to widespread social unrest and hunger—even catastrophic global famine.

How Africa is affected by climate change?

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.

What happens if precipitation decreases?

Too little precipitation can result in dry soil, shallow streams, and shortages of municipal water supplies. However, too much precipitation can also have a negative impact on human activities, business and industry, agriculture, and the environment.

What are the negative effects of climate change?

More frequent and intense drought, storms, heat waves, rising sea levels, melting glaciers and warming oceans can directly harm animals, destroy the places they live, and wreak havoc on people’s livelihoods and communities. As climate change worsens, dangerous weather events are becoming more frequent or severe.

What will happen if precipitation patterns change?

Changes in precipitation patterns will impact people and ecosystems by altering the availability of water throughout the year. The predicted impacts of altered precipitation patterns include: Floods and droughts will become more frequent and more severe. Wildfires are expected to become stronger and more common.

Does climate change mean less rain?

Just as precipitation patterns vary across the world, however, so do the precipitation effects of climate change. By shifting the wind patterns and ocean currents that drive the world’s climate system, climate change will also cause some areas to experience decreased precipitation.

Is rainfall change a global issue?

Global precipitation patterns are being moved in new directions by climate change, a new study has found.

What is Ghana’s climate?

Ghana’s climate is tropical and strongly influenced by the West African monsoon. Seasonal variations in temperature in Ghana are greatest in the north, with highest temperatures in the hot, dry season (April, May, and June) at 27‐30°C; further south, temperatures are lower (June, August, September) at 22‐25°C.

What are the types of climate change?

There are approximately five main climate types on Earth:

  • Tropical.
  • Dry.
  • Temperate.
  • Continental.
  • Polar.

How does climate change affect food production in Ghana?

This study indicates that there will be a reduction in the suitability of multiple crops in Ghana under climate change. Areas which are currently optimally and moderately suitable for production of the four crops will decrease while areas marginally and moderately suitable for two or more crops will increase.
