Abandoned farmland and the environment

September 4, 2025 By EarthWise Leave a Comment

Abandoned farmland has been increasing dramatically in recent decades. Estimates are that a billion acres – an area half the size of Australia – have been relinquished from cultivation globally. While more and more of the tropics have been cultivated in recent times, the global amount of land used for agriculture has been in decline since 2001. In the past 30 years, arable land in the United States has declined by almost a sixth. The situation in Europe is similar. Huge amounts of the former Soviet Union now lie abandoned.

Farmland is abandoned for various reasons. It may suffer from damaged soil so that crop yields are too low to be worth the effort. Farm owners may become too old or be physically unable to continue farming. Many younger people head for jobs in the cities and more attractive opportunities. Wars, natural and man-made disasters, and political turmoil have all contributed.

Another form of largely ignored lands are so-called degraded forests. These are forests that were logged in the past but are no longer productive and aren’t protected either. These places also represent unused land with great potential value.

Ecologists point to the potential of these lands as neglected resources for rewilding efforts, improving biodiversity, and for increasing natural ways to capture carbon. Left to its own devices, nature will usually reclaim abandoned places. This generally provides benefits for biodiversity and climate. But mapping, studying, managing, and protecting the increasingly vast tracts of abandoned land could increase their potential to contribute to climate change mitigation and the restoration of species and their habitats.

The slow decline of coal

January 25, 2024 By EarthWise Leave a Comment

Despite the fact that coal is the dirtiest and most climate-harmful energy source we have, the global demand for it hit a record high in 2023. The demand for coal grew by 1.4% worldwide, according to an analysis by the International Energy Agency.

Coal use grew by 5% in China and 8% in India. The two countries are the world’s largest producers and consumers of coal. Meanwhile, coal use in the U.S. and the European Union fell by 20%.

Despite this discouraging news, the IEA forecasts that coal use will decline over the next two years. There have been declines in coal demand a few times before, but they were driven by unusual events such as the collapse of the Soviet Union and the Covid-19 crisis. But the IEA says that the forthcoming decline is different. It will be driven by the formidable and sustained expansion of clean energy technologies.

According to the IEA, global coal demand will fall by 2.3% by 2026 even in the absence of new policies to curb coal use. Forces at play will be increased hydropower in China as it recovers from drought and puts new wind and solar projects online. China is responsible for more than half of global coal demand, but it is also responsible for more than half of the planned renewable power projects coming online over the next three years. Experts believe that with these forthcoming projects, Chinese emissions may have peaked in 2023.

The projected drop in coal demand is still far short of what is required for the world to avoid catastrophic warming. Much greater efforts are needed to meet international climate targets.

Russian Forests And Climate Mitigation | Earth Wise

August 24, 2021 By EarthWise Leave a Comment

Russia is the largest country in area in the world, almost equal in size to the sum of the next two largest – Canada and the U.S. Russia is also the world’s largest forest country, containing more than one-fifth of the world’s forests. As a result, the country’s forests and forestry activities have enormous potential for impacting climate mitigation.

Since the dissolution of the USSR, there has been a decline in the availability of information on the state of Russia’s forests. The Soviet Forest Inventory and Planning System compiled information until 1988. Since then, the Russian National Forest Inventory has been the source of forest information on the national scale, and it hadn’t produced a comprehensive inventory until 2020.

The new data indicates that Russian forests have in fact accumulated a large amount of additional biomass over the intervening years. Using the last Soviet Union report as a reference point, the new results show that the ongoing stock accumulation rate in Russian forests over the 26-year period is of the same magnitude as the net forest stock losses in tropical countries.

Thus, it is clear that Russian forests have great potential in terms of global climate mitigation as well as potential co-benefits relating to the green economy and sustainable development. It is important to note that as the impact of climate change increases, disturbances to the Russian forests could have severe adverse effects on global climate mitigation efforts.

While much of the world’s attention is rightfully upon tropical rainforests in the Amazon and elsewhere, it is important to not ignore the largest country in the world hosting the largest land biome on the planet where even small percentage changes in the amount of forest biomass could have a major global impact.
