Synopsis (short abstract) China is the world's largest sugar importer, third-largest sugar consumer and fourth largest sugar crop producer. Key regions for sugarcane and sugar beet production are Guangxi Zhuang Autonomous Region and Inner Mongolia Autonomous Region, respectively. Sugarcane covers one million hectares in Guangxi, 60 percent of China's total, while Inner Mongolia hosts 80 000 hectares of sugar beet, 36 percent of the national total. The sugar industry is crucial for local economies and farmer incomes in these areas. Despite China's advantages in sugar crop cultivation, sugarcane planting areas decreased from 1.7 million hectares in 2013 to 1.37 million hectares in 2017, a trend assessed as likely to continue due to rising production costs, particularly for chemical fertilizers, and shrinking profit margins. Overuse of chemical fertilizers led to soil degradation, reducing the production potential of sugar crops and causing environmental issues like water pollution and erosion. In addition, sugar processing generates significant waste, including bagasse, pulp and molasses. These by products, rich in organic matter and nutrients, are underutilized, contributing to pollution and greenhouse gas emissions. Using these wastes as organic fertilizers could reduce chemical fertilizer use, lower production costs and improve soil fertility.

    Green Climate Fund Project Formulation, Readiness and Start-Up Support: Sustainable Ecosystem-Based Transformation of Natural Resource Management in Kyrgyzstan (SET NRM) - TCP/KYR/3606 2020

    Kyrgyzstan is one of the most vulnerable countries to the impacts of climate change in Central Asia It is affected by drought, land and mudslides while flooding events and river banks erosion are set to increase in frequency and intensity Recurrent extreme weather events and marked changes in microclimate are already being observed with particular magnitude in target areas Forests and pastures are among the most sensitive resources being impacted by climate change and reduced productivity of low altitude pastures and decreased resilience of forest ecosystem are increasing the vulnerability of communities and negatively impacting rural livelihoods Climate change, coupled with unsustainable management of natural resources, threatens both key ecosystems and Kyrgyzstan’s cultural heritage and development opportunities The Government of Kyrgyzstan is developing plans and programmes to tackle climate change however, significant resources are needed to implement them Against this background, the Government requested that FAO provide technical assistance to design and start up a Green Climate Fund ( funded investment project aimed at increasing mitigation, climate resilience and low emission sustainable development as well as preparing a funding proposal for the project, and strengthening stakeholder capacity to implement it.

    Conservation and Sustainable Management of Black Soil in Jilin Province - TCP/CPR/3806 2024
    Also available in:
    No results found.
    Black soils cover around 1.03 million square metres in Northeast China and produce between 22.5 and 25 million tonnes of commercial grains annually. However, unlimited exploitation and unsustainable farming practices on these fragile soils through intensive tillage, which has led to depriving the land of soil organic carbon (SOC), as well as excessive removal of organic matter and unregulated use of chemical fertilizers over the past few decades have produced significant land degradation, nutrient imbalance and an annual average loss of 0.3-1.0 cm of the black soil layer. Due to its inherent fertility, recovering black soils is essential to ensure food security in China, and maintaining SOC is crucial to enhance black soils resilience against droughts and extreme temperatures caused by climate change. Jilin Province in Northeast China is one of the most affected, given that great part of the area is rich in black soils. Although the government implemented several regulations, the province is facing several technical challenges to increase SOC and return crop residues to the land. In order to address this situation, this project aimed to develop sustainable and appropriate technical guidelines and policy recommendations to improve black soils management in Northeast China, which would contribute to food security and sustainable production systems.

    Supporting the Restoration of Degraded Forest-Steppe and Steppe Zones in Ukraine through Integrated Natural Resources Management - GCP/UKR/004/GFF 2024
    Also available in:
    No results found.
    Ukraine is known for being home to nearly 40 percent of the world’s chernozems, black soils that are extremely fertile and productive. Years of intensive agricultural production has led to the deterioration and erosion of these soils, depleting them of their organic matter and nutrients.Lines of trees known as shelterbelts were planted in the 1930s in the forest- steppe and steppe zones of Ukraine to combat erosion and improve soil quality; however, deforestation and continued intensive agricultural practices have worsened the wind and water erosion. A reduction in the amount of irrigated land in these zones has also contributed to the degradation of the chernozems. This project was formulated to restore the productivity and resilience of Ukraine’s black soils through the expansion of integrated natural resource management (INRM) practices, the restoration of shelterbelts and the establishment of regulations on their ownership and management, the introduction of agroforestry, and the creation of an enabling policy environment for sustainable land management (SLM).
