How climate affects vegetation in Africa?

Climate influences plant growth via temperature effects on leaf level photosynthesis, maintenance respiration and phenology. Atmospheric CO2 influences photosynthetic rates, water use efficiency and indirectly, the growing season length and reproduction.

How does climate affect vegetation?

Climate change affects the growth of plants in three ways. First, as CO2 levels increase, plants need less water to do photosynthesis. This well-documented effect was long thought to mean that there would be more fresh water available in soils and streams.

How is climate change affecting 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 does climate influence the natural vegetation of an area?

The major effect of a blanket of vegetation is to moderate most daily climatic changes, such as changes in temperature, humidity, and wind. (However, plants generate daily variations in concentrations of oxygen and carbon dioxide through their photosynthetic and respiratory activities.)

What are the major factors of climate that affect vegetation pattern?

Precipitation and temperature are the dominant climatic factors affecting vegetation growth [11,19].

What plants are most affected by climate change?

5 Major Crops In The Crosshairs Of Climate Change

  • Wheat. Wheat, source of bread and a foundation of life in much of the world, will suffer from hotter temperatures — and the country where the impact may be greatest also is among least well-equipped to cope with a shortfall. …

How does climate affect soil and vegetation?

While weather is a short-term part of climate, certain weather cycles can still affect soil. For example, soil can be dried out and rearranged during droughty or windy weather. As the soil is dried out, plant growth is reduced, which reduces the stability of the surface layer and allows more erosion.

Which African country is most affected by climate change?

MADAGASCAR (Climate Risk Index: 15.83)

Adverse weather events have also made the African country one of the most vulnerable to climate change with 72 deaths — 0.27 per 100,000 inhabitants — about 568 million dollars in economic losses and a drop in per capita GDP of 1.32%.

Why is Africa most affected by climate change?

According to the Intergovernmental Panel on Climate Change, the vulnerability of Africa to climate change is driven by a range of factors that include weak adaptive capacity, high dependence on ecosystem goods for livelihoods, and less developed agricultural production systems.

What are three 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 is the difference between climate and vegetation?

Vegetation does not completely cover the land surface. The drier the climate is, the scarcer is the vegetation and the greater is the fraction of bare soil. The physical characteristics of bare soil (albedo, roughness, and water conductivity) differ from those of vegetation cover.

What are the factors affecting vegetation distribution?

All four edaphic factors (soil salinity, soil moisture, soil pH, soil organic matter) had significant correlations with vegetation types. Soil salinity was identified as the most important factor in shaping vegetation patterns, followed by soil moisture, soil pH, and soil organic matter.

What two factors determine the type of vegetation?

Vegetation regions can be divided into five major types: forest, grassland, tundra, desert, and ice sheet. Climate, soil, the ability of soil to hold water, and the slope, or angle, of the land all determine what types of plants will grow in a particular region.

What are the different kinds of vegetation growing in Africa?

Due to varied climatic conditions, India has a wide range of natural vegetation. Vegetation of India can be divided into five types – Tropical evergreen forest, Tropical deciduous forest, Thorny bushes, Mountain vegetation and Mangrove forests.

How does climate affect grasslands?

Drought is a major driver of impacts to grassland and prairie ecosystems, and is likely to lead to increased wildfires and loss of wetland habitats – such as prairie potholes that are critical habitat for migratory bird species – as well as species migration and habitat shifts. …
