Recent climate events such as extremely high temperatures and widespread drought have focused government and public attention on the effects of climate change in Australia. [8] Rainfall in southwestern Australia has decreased by 10–20% since the 1970s, while southeastern Australia has also experienced a moderate decline since the 1990s. [5]
The majority of cleared land in Australia has been developed for cattle, sheep and wheat production. 46.3% of Australia is used for cattle grazing on marginal semi-deserts with natural vegetation. This land is too dry and infertile for any other agricultural use (apart from some kangaroo culling).
Climate change has been a critical issue in Australia since the beginning of the 21st century. Australia is becoming hotter and more prone to extreme heat, bushfires, droughts, floods, and longer fire seasons because of climate change. Climate issues include wildfires, heatwaves, cyclones, rising sea levels, and erosion. [16] [17] [18] [19]
Climate change also has diverse implications for Australia's economy, agriculture and public health. [9] Projected impacts include more severe floods, droughts, and cyclones. [10] Furthermore, Australia's population is highly concentrated in coastal areas at risk from rising sea levels, and existing pressures on water supply will be exacerbated.
Climate change will accelerate the prevalence of pests and diseases and increase the occurrence of highly impactful events. [195] The impacts of climate change on agricultural production in Africa will have serious implications for food security and livelihoods. Between 2014 and 2018, Africa had the highest levels of food insecurity in the ...
This year's U.N. climate conference in Dubai will be the first to dedicate a whole day to the question of how to reduce food's climate impact, and advocacy groups are pressing countries to come up ...
Regenerative agriculture mitigates climate change through carbon dioxide removal from the atmosphere and sequestration. Along with reduction of carbon emissions, carbon sequestration is gaining popularity in agriculture, and individuals as well as groups are taking action to fight climate change. [80] Hoverfly at work
