Book (series)Guidelines to control water pollution from agriculture in China
Decoupling water pollution from agricultural production
2013Also available in:
No results found.Deterioration of water quality is considered a key constraint to future economic development and social progress in China, and agriculture is known to be a major source of pollution. Agricultural systems in China have expanded and intensified to meet increasing food demand related to population growth and changes in diet. This has led to greatly increased pressure on water quality. Huge amounts of agrochemicals, organic matter, drug residues, sediments and saline drainage are being discharged every year into water bodies. Water pollution from rural sewage has also increased with the rapid development of the economy and improving living standards in rural areas. Rural sewage is estimated to be about 9 billion tonnes a year; most is discharged into the environment untreated. The resulting increased concentrations of pollutants in water bodies pose demonstrated risks to aquatic ecosystems, human health and productive uses. These guidelines produced by the F ood and Agriculture Organization of the United Nations (FAO) and the Institute of Environment and Sustainable Development in Agriculture (IEDA) of the Chinese Academy of Agricultural Sciences (CAAS) review the key pressures and impacts from the main agricultural and rural activities (i.e. cultivation, animal raising, aquaculture, and rural living) and propose a set of good agricultural practices and economic and regulatory actions to minimize pollution and to move towards a more sustainable agriculture intensification in a greener economy. -
DocumentAnalyzing the occurrence trend of sediment-related disasters and post-disaster recovery cases in mountain regions in North Korea based on a literature review and satellite image observations
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.This study investigated spatiotemporal trends of sediment-related disasters in North Korea from 1960 to 2019 and post-disaster recovery cases based on a literature review and satellite images. Results showed that occurrence status of sediment-related disasters was initially externally reported in 1995 (during the Kim Jongil era); their main triggering factor was heavy summer rainfall. Furthermore, forest degradation rate was positively correlated with population density (R2 = 0.4347, p = 0.02) and occurrence number of sediment-related disasters was relatively high on the west coast region, where both variables showed high values. This indicates that human activity was a major cause of forest degradation and thus, significantly affected sediment-related disasters in mountain regions. Finally, sediment- related disasters due to shallow landslides, debris flow, and slow-moving landslides were observed in undisturbed forest regions and human-impacted forest regions, including terraced fields, opencast mines, forest roads, and post-wildfire areas, via satellite image analysis. These disaster-hit areas remained mostly abandoned without any recovery works, whereas hillside erosion control work (e.g., treeplanting with terracing) or torrent erosion control work (e.g., check dam, debris flow guide bank) were implemented in certain areas. These findings can provide reference information to expand inter-Korean exchange and cooperation in forest rehabilitation and erosion control works of North Korea.

ProjectEmergency Support to the Rehabilitation of the Agricultural Production for Farmers Affected by Floods in Kirehe District - TCP/RWA/3705 2023
Also available in:
No results found.Kirehe District has been severely impacted by a number of climate hazards, including a protracted drought and recent strong rainfall, which have increased the risk of unprecedented run offs that, in turn, could result in flooding and landslides The destruction of homes, top soil erosion and crop submergence are among the disastrous consequences in marshlands, where more than 50 ha of rice crops have already been destroyed Kigarama Kigina Nyamugari Mahama Nyarubuye and Mpanga were six of the 12 sectors in Kirehe that were particularly affected Between January and March 2019 17 people were killed, 1 613 houses razed and 1 381 kitchens and toilets destroyed At least 3 954 ha of crops were damaged, with 90 household animals decimated Livelihoods are becoming a challenge in such areas, particularly since the majority of the population relies on casual agricultural labour and subsistence farming.
