[Evaluation of sustainable intensification in agriculture: Research progress and prospects].

Sustainable intensification in agriculture (SI) is a realistic pathway to ensure global food security and deal with famine, poverty, and climate change. We constructed a SI research framework using methods such as literature, induction, and deduction. We reviewed the progress of SI research from four aspects, including the conceptual origin, index system, research scale, and evaluation methods.

[Spatial-temporal pattern of sustainable intensification of agricultural land-use in Shandong Province, China.].

Under the theoretical framework of sustainable intensification of agricultural land-use (SIALU), We used material flow analysis (MFA) method to establish evaluation index system for SIALU by utilizing data in 2000, 2005, 2010 and 2015 to quantify the level of SIALU of 17 cities in Shandong Province, and analyzed the variation in input-output of resources factors of agricultural land, spatial distribution of resource productivity and environmental economic efficiency, in order to reveal spatial-temporal differentiation of SIALU. Results showed that the direct material input to agricultural lands decreased, whereas hidden flow, stock and pollutant emissions increased gradually from 2000 to 2015. The material productivity of all cities in the province showed that the coastal areas in the peninsula were relatively lower than the southern region, and the level of material productivity in the northwest region was relatively higher.
