“…Developing such areas requires massive energy inputs like fuel, fertilisers, irrigation and land levelling which, according to Montarella ( 2014 ), ultimately results in highly unsustainable agricultural models. This fi nding accords with a study of urban expansion in China, where the new agricultural land developed to replace losses to urban expansion was 80 % less productive (Huimin Yan et al 2009 ).…”

The Department of Agriculture and Food, Western Australia, has worked closely with state and local planners and agricultural practitioners over the last 4 years to develop a new way to identify high quality agricultural land (HQAL). This methodology combines land capability or suitability for horticulture and dry land cropping and grazing with irrigation supplies, rainfall and yield information. It then ranks large tracts of "similar" land according to its versatility for a range of agricultural land uses. This information, developed in a pilot project in the mid west region of Western Australia (WA) has been designed to suit formal land use planning. The HQAL methodology is being extended to other parts of Western Australia (WA) and has value for local planning. To use this information effectively more work is required state-wide and nationally to establish the relative importance of HQAL in many locations, including those near cities and towns.

“…In China, many scientists are devoted to exploring crop potential productivity due to the need for agricultural modernization (Yu and Zhao, 1982;Tang, 1997;Gao et al, 2004;Yan et al, 2009). Especially with population growth and urban land expansion leading to cultivated land loss and environment degradation, the increase of grain production is increasingly vital, prompting an urgent need for the raise of agricultural production (Seto et al, 2000;Deng, 2008a).…”

Estimation of land production and its response to cultivated land conversion in North China Plain

et al. 2011

Food safety and its related influencing factors in China are the hot research topics currently, and cultivated land conversion is one of the significant factors influencing food safety in China. Taking the North China Plain as the study area, this paper examines the changes of cultivated land area using satellite images, estimates land productivity from 1985 to 2005 using the model of Estimation System for Land Productivity (ESLP), and analyzes the impact of cultivated land conversion on the land production. Compared with the grain yield data from statistical yearbooks, the results indicate that ESLP model is an effective tool for estimating land productivity. Land productivity in the North China Plain showed a slight decreasing trend from 1985 to 2005, spatially, increased from the north to the south gradually, and the net changes varied in different areas. Cultivated land area recorded a marginal decrease of 8.0 × 10 5 ha, mainly converted to other land uses. Cultivated land conversion had more significant negative impacts on land production than land productivity did. Land production decreased by about 6.48 × 10 6 t caused by cultivated land conversion between 1985 and 2005, accounting for 91.9% of the total land production reduction. Although the land productivity increased in Anhui and Jiangsu provinces, it can not offset the overall adverse effects caused by cultivated land conversion. Therefore, there are significant meanings to control the cultivated land conversion and improve the land productivity for ensuring the land production in the North China Plain.

“…GLO-PEM consists of linked components that describe the absorption and use of canopy radiation and autotrophic respiration and the regulation of these processes by environmental factors including temperature, water vapor-pressure deficit, and soil moisture [35][36][37][38]. We used GLO-PEM and NOAA/NASA Pathfinder Advanced Very High Resolution Radiometer (AVHRR) Land (PAL) data at resolutions of 8 km and 10 days to estimate NPP for 1990NPP for , 1995NPP for , 2000NPP for , 2005NPP for and 2010.…”
