This article seems tilted in a pro-environmentalist direction. While I personally agree with this viewpoint, it does seem to have bias that is uncharacteristic of a good Wiki article, and I feel that someone who knows what they're doing should revise it for neutrality.

"The growing population pressure, during 1980–1990, has led to decreases in the already small areas of agricultural land per person in six out of eight countries (14% for India and 21% for Pakistan)." and "High population density is not always related to land degradation. Rather, it is the practices of the human population that can cause a landscape to become degraded. Populations can be a benefit to the land and make it more productive than it is in its natural state." I'm now translating this article into traditional Chinese, I just can't understand them without proper citations. Thanks. ThomasYehYeh (talk) 05:02, 7 March 2023 (UTC)Reply

Firstly @Cerealisgoodsoup My comments below are not a criticism of your work. I presume like most student editors after their courses you are not active on Wikipedia at the moment so that is why I refer to you in the third person, but if you would like to join the discussion please do so and we can talk directly.
Although I have not noticed anything incorrect with the info @Cerealisgoodsoup has added it is very detailed about 2 causes of land degradation which are probably both a very minor part of total land degradation (compared to say agriculture). So I feel the article does not have a neutral point of view.
Cerealisgoodsoup's additions come across as a focused attack on the two land uses rather than adding to the understanding of the subject. Many of the concerns listed for the two land uses are not types of land degradation. When non-land degradations are excluded, there are no degradation types specific to these uses. I support removing the 2 sections per WP:IRI and WP:ICW -- Paleorthid (talk) 02:27, 14 October 2025 (UTC)Reply
Solar power is widely considered an alternative, sustainable, and renewable energy source compared to fossil fuels. However, it has adverse environmental impacts. There are six types of impacts:[1]
Soil erosion, the construction of solar plants require vegetation removal, land grading, soil compaction, and construction of access roads all of which contribute to soil erosion. Additionally, changes in the natural landscape can lead to an increase in stormwater runoff further exacerbating soil erosion.[2]
Water, usage of water occurs at all stages of a solar plant's development (construction, operation, and decommissioning) in the form of dust suppression, cooling, and cleaning. Concentrating solar power (CSP) in particular, generally requires excessive water usage for cooling purposes. For this reason alone, solar plant sites and their water consumption should be closely examined as access to fresh water becomes more scarce.[3]
Emissions, solar energy systems do not emit carbon into the atmosphere during operation directly. However, no human development project can completely avoid some impacts on the environment, solar plants can be indirectly connected to manufacturing, transportation, and construction.[4]
Hazardous waste, the manufacturing of photovoltaic (PV) cells includes a number of hazardous materials. Such materials include compounds of cadmium (Cd), selenium (Se), and lead (Pb).[1]
Vegetation and wildlife, both are directly and indirectly impacted by solar power plant constructions. Large-scale solar plants require intense clearing of land, which affects native vegetation, habitat, and ultimately, the loss of wildlife. The construction of utility-scale solar energy (USSE) contributes to avian mortality. USSE-related avian mortality was estimated to be between 16,200 and 59,400 birds in the Southern California region. This statistic was extrapolated to be between 37,800 and 138,600 birds for all USSE facilities across the United States.[5] Solar energy plants are being constructed in a wide range of environments and ecosystems such as forests, grasslands, deserts, and farmlands. Forests typically have the highest levels of biodiversity, biomass density, and cloud cover therefore construction of solar energy plants in these regions will have the most adverse effects on vegetation and wildlife.[6] In Japan, some large-scale solar power plants, known as "mega solar", covered more than 100 hectares (250 acres) on mountain sides. To make way for these farms, forest are being cleared.[7] In some case, such as the megasolar plants in Kushiro wetlands in Hokkaido which are being built near the Kushiro-shitsugen National Park where designated endangered species live.[8]
Land use footprint, in comparison to fossil fuel-based plants, solar energy plants have higher land use efficiency. Land use efficiency of solar energy plants can be further minimized by construction plants in abandoned mines or in conjunction with other renewable energy operations such as wind or facilities such as a water treatment plant.[9]
Similar to previous, wind power is also a relatively clean source of energy but it also has adverse environmental impacts. There six types of impacts:
Visual, typically located in rural or natural regions, wind energy power plants are commonly viewed as an opposing element to the natural landscape and are associated with industry among local residents and environmental activists.[10]
Noise, there are two types of noises produced by wind turbines, aerodynamic and mechanical. Aerodynamic noise comes from turbine blades circulating. This type of noise is varied and based on the size of turbines, wind speed, and blade rotation speed. Mechanical noise comes from the turbine's internal mechanisms and parts. This type is varied by the quality of sound insulation. Unlike aerodynamic noise, mechanical noise does not increase with the overall size of wind turbines.[1] Additionally, reported health problems attributed to noise from wind turbines include a list of symptoms such as sleep disorders, headaches, mood disorders, inability to concentrate, tinnitus, and vestibular problems.[11]
Electromagnetic interference, wind turbines can cause disruption to local radios, television, microwave communication systems, and navigational systems by generating electromagnetic interferences.[12]
Local climate, wind masses that move through the blades of a wind turbine experience losses in momentum. This change in atmospheric dynamics could lead to an increase in the temperature of the surrounding environment due to weaker winds that would otherwise provide cooling effects.[13]
Vegetation and wildlife, similar to solar plants, wind turbine plants also require large-scale clearing of land, vegetation, and soil erosion all of which will result in adverse effects on wildlife. Wind turbine plants can directly impact the mortality of wildlife (birds and bats) through collision mortality and indirectly through loss of habitats.[13]
Wind turbines on farmlandLand use footprint, the use of land for wind turbines depends on the terrain with flatter areas requiring more land than those in hilly areas. Wind turbine plants can operate in conjunction with other land uses such as agriculture and solar without affecting energy production.[14]
