Le ministère chinois de l'Agriculture a validé la création de "zones de démonstration agricole à l'international" dans 10 pays, rapporte Reuters. Objectif : accroître son influence sur le secteur agricole mondial.

Parmi les projets, l'un est en Zambie portant sur une zone de transformation des produits agricoles, un autre au Laos pour un parc de technologies agricoles, un au Fiji pour un parc à pêche.

Trans-Pacific View author Mercy Kuo regularly engages subject-matter experts, policy practitioners, and strategic thinkers across the globe for their diverse insights into U.S. Asia policy. This conversation with Dr. Spencer Cohen – Senior Economist at Community Attributes, a Seattle-based research consultancy, and former senior policy adviser for the Washington Economic Development Commission – is the 102nd in “The Trans-Pacific View Insight Series.”

Recent expansion of the scale of human activities poses severe threats to Earth’s life-support systems. Increasingly, protected areas (PAs) are expected to serve dual goals: protect biodiversity and secure ecosystem services. We report a nationwide assessment for China, quantifying the provision of threatened species habitat and four key regulating services—water retention, soil retention, sandstorm prevention, and carbon sequestration—in nature reserves (the primary category of PAs in China).

The Geoscience Laser Altimeter System (GLAS) instrument onboard the Ice, Cloud and land Elevation Satellite (ICESat) provides elevation data with very high accuracy which can be used as ground data to evaluate the vertical accuracy of an existing Digital Elevation Model (DEM). In this article, we examine the differences between ICESat elevation data (from the 1064 nm channel) and Shuttle Radar Topography Mission (SRTM) DEM of 3 arcsec resolution (90 m) and map-based DEMs in the Qinghai-Tibet (or Tibetan) Plateau, China.

The Holdridge life zone (HLZ) model has been improved to help classify the biome transition zone (BTZ) in China's Loess Plateau. A positive and negative transformation index of land-cover (PNTIL) was developed to quantitatively evaluate the land-cover changes in every type of BTZ. Three bioclimatic datasets, with a spatial resolution of 1km×1km, were used to classify the BTZ type in Loess Plateau. These include the mean annual biotemperature (MAB), average total annual precipitation (TAP) and potential evapotranspiration ratio (PER).

Complex changes in carbon sources and sinks caused by rapid urbanization have been observed with extensive changes in the quantity, structure, and spatial pattern of land use types. Based on the modified Carnegie-Ames-Stanford Approach model and on gray relational analysis, we analyzed the influence of land use changes on carbon sinks and emissions in Guangzhou from 2000 to 2012. The aim was to identify suitable options for built-up land expansion that would allow for minimal carbon losses.

Fine particulates less than 2.5 μm (PM2.5) or 10 μm (PM10) are often emitted from river bank or other alluvial lands to the atmosphere during dry and windy seasons worldwide, which contribute to land degradation and poor air quality. Investigation of PM2.5 and PM10 emission potential could contribute to the development of mitigation strategy and better land management practices. In the lowprecipitation zone (<100 mm annual precipitation) of the Tarim Basin in western China, wind erosion and fugitive dust emission are recognized problems on the oasis.

Literatures about factors affecting demand scale of rural land circulation are reviewed. Based on this, a total of 5 deficiencies in these literatures are put forward, which are the inconsistency between model selection and sample data type in some literatures, the lack of analysis from the perspective of internal family, the incomplete or inaccurate research factors, the lack of analysis on causation, and the mixture of inflow and outflow of land circulation.

Land degradation and poverty are problems that must be tackled together for environmental conservation to succeed. However, it is rarely possible to move a population from degraded land to another area where the people can be more easily sustained. To find a new strategy that achieves both conservation and economic gains without the need to relocate a population, we examined/investigated a sustainable combination of ecological and economic development suitable for the restoration of areas of China with collapsing gullies, where the frequent steep slopes make restoration difficult.
