“…The main sources of heavy metals in farmland soils include mining and smelting, sewage irrigation, sludge reuse and fertilizer application (Chen et al, 1999). Due to extensive and nonstandard production processes of some mining and smelting enterprises, large quantities of heavy metals affect farmland through wastewater irrigation, waste transportation, sludge application and atmospheric deposition which has been shown to be particularly important in southern China with abundant mineral resources (Hu et al, 2014;Xu et al, 2014). Extensive irrigation with poorly treated water from sewage in China has been employed since the 1950s, with the affected area increasing from 115 km2 in 1957 to 36000 km2 in 1998 (Huang and Wang, 2009), remaining above 30000 km2 since then.…”

Impacts of Soil and Water Pollution on Food Safety and Health Risks in China AbstractEnvironmental pollution and food safety are two of the most important issues of our time. Soil and water pollution, in particular, have historically impacted on food safety which represents an important threat to human health. Nowhere has that situation been more complex and challenging than in China, where a combination of pollution and an increasing food safety risk have affected a large part of the population. Water scarcity, pesticide over-application, and chemical pollutants are considered to be the most important factors impacting on food safety in China. Inadequate quantity and quality of surface water resources in China have led to the long-term use of waste-water irrigation to fulfill the water requirements for agricultural production. In some regions this has caused serious agricultural land and food pollution, especially for heavy metals. It is important, therefore, that issues threatening food safety such as combined pesticide residues and heavy metal pollution are addressed to reduce risks to human health. The increasing negative effects on food safety from water and soil pollution have put more people at risk of carcinogenic diseases, potentially contributing to 'cancer villages' which appear to correlate strongly with the main food producing areas. Currently in China, food safety policies are not integrated with soil and water pollution management policies. Here, a comprehensive map of both soil and water pollution threats to food safety in China is presented and integrated policies addressing soil and water pollution for achieving food safety are suggested to provide a holistic approach.

“…The loss of semi-natural or natural landscape within the cultivated area would reduce the effective area of habitat [17,28]. Moreover, close proximity to the construction landscape would also introduce a higher risk of pollution for the cultivated soil [38,39]; hence, the LES of cultivated land could be compromised on account of the surrounding landscape. In addition, the social-economic changes triggered by cultivated landscape variations also concern the ecological security of cultivated land resources.…”

Decreased Landscape Ecological Security of Peri-Urban Cultivated Land Following Rapid Urbanization: An Impediment to Sustainable Agriculture

Abstract:The sustainable management of peri-urban agriculture requires cultivated land to not only be a source of food production, but also contribute ecological resources. This paper presents a method for assessing the landscape ecological security (LES) of peri-urban cultivated land that considers both cultivated landscape and interactions with the surrounding landscape. The situation in Changchun City was assessed at three time nodes. Furthermore, its spatiotemporal variations in several landscape characteristics were also measured. The results suggest that the peri-urban cultivated landscape was affected to varying extents by urbanization. The metrics of PD (patch density), ED (edge density), AWMSI (area-weighted mean shape index), FRAC (fractal dimension) and DIVISION (landscape division index) progressively increased during urbanization for cultivated land within 20 km of the urban gravity center. Elevated fragmentation and vulnerability of the cultivated landscape was also detected. The traditional method for quantifying LES of cultivated land neglects interactions with other landscape types. When the impacts of the ecological and construction landscapes were included, the results better reflected the dynamics of cultivated landscape in a peri-urban area. Decreased LES of cultivated land poses an impediment to the sustainable peri-urban agriculture, and better management practices should be applied for maintaining the LES of peri-urban cultivated land resources.
