Black carbon in urban soils: land use and climate drive variation at the surface

Description: The authors of this article conducted a literature review of black carbon in urban soils and found that black carbon comprises a major fraction of the total organic carbon in urban surface soils, yet sampling bias towards the surface could hide the potential for black carbon storage at depth. The authors recorded data on city, climate, and land use/land cover characteristics to examine drivers of black carbon content and contribution to total organic carbon in soil.

Spatial Targeting of Agricultural Support Measures: Indicator-Based Assessment of Coverages and Leakages

Description: This article evaluates the targeting strategy of a national-level program in Mexico that distributed agricultural support based on seven criteria that prioritized poor smallholder farming communities at high risk of cropland failure. The findings highlight the continued lack of financial support for smallholder agriculture in Mexico, despite program rules and priority statements that stress the vulnerability of this sector. The article also illustrates the important role of spatial targeting in… more

Land Use Simulation of Guangzhou Based on Nighttime Light Data and Planning Policies

Description: This article employs nighttime light (NTL) information as a proxy indicator of gross domestic product(GDP), and a future land use simulation model (FLUS) to simulate the land use patterns in Guangzhou from 2015 to 2018 and 2018 to 2035 by incorporating planning policies. This study demonstrates that NTL is a suitable and feasible proxy indicator of GDP for the land use simulations, providing a scientific basis for the development of urban planning and construction policy.

Urban edge trees: Urban form and meteorology drive elemental carbon deposition to canopies and soils

Description: Article asserts that urban tree canopies are a significant sink for atmospheric elemental carbon (EC)--and air pollutant that is a powerful climate-forcing agent and threat to human health. The authors' findings indicate that complex configurations of roads, buildings, and vegetation produce “urban edge trees” that contribute to heterogeneous EC deposition patterns across urban systems, with implications for greenspace planning.
