- Description: Ecosystem services in oil palm plantations owned by smallholders in four villages in the Riau Province, Indonesia were identified and valued. Nine provisioning, three regulating and maintenance, one cultural ecosystem service, and a single ecosystem dis-service, were identified from interviews with 62 farming households. Direct and indirect market valuation methods were used to estimate the total economic value (TEV) of these services, which averaged USD 6520 ha-1 year-1 (range = USD 2970-7729 ha-1 year-1). The values of provisioning services were USD 4331 ha-1 year-1 (range = USD 2263-5489 ha-1 year-1), regulating and maintenance services were valued at USD 1880 ha-1 year-1 (range of USD 707-3110 ha-1 year-1), and cultural services were USD 309 ha-1 year-1. We conclude that identifying and valuing ecosystem services offers an opportunity to improve the environmental and economic sustainability of smallholders in oil palm landscapes in Indonesia. © 2020 by the authors.

- Description: Inadequacies of the current agriculture and food systems are recognised globally in the form of damages to environment and human health. In addition, the prevailing economic and policy systems do not reflect these damages in its accounting systems and standards. These shortcomings lead to perverse and pervasive outcomes for society at large. Our proposal is to consider all social and environmental externalities – both negative and positive, in global agriculture and food systems and reflect them in an economic system by evaluating comprehensive costs and benefits. This can be done by adopting an innovative, universal, and inclusive framework (the ‘TEEBAgriFood’ framework) in order to stimulate appropriate policy responses. © The Author(s) 2019. **Please note that there are multiple authors for this article therefore only the name of the first 5 including Federation University Australia affiliate “Harpinder Sandhu” is provided in this record**

- Description: One of the major consequences of expansive urban growth is the degradation and loss of productive agricultural land and agroecosystem functions. Four landscape metrics-Percentage of Land (PLAND), Mean Parcel Size (MPS), Parcel Density (PD), and Modified Simpson's Diversity Index (MSDI)-were calculated for 1 km × 1 km cells along three 50 km-long transects that extend out from the Adelaide CBD, in order to analyze variations in landscape structures. Each transect has different land uses beyond the built-up area, and they differ in topography, soils, and rates of urban expansion. Our new findings are that zones of agricultural land fragmentation can be identified by the relationships between MPS and PD, that these occur in areas where PD ranges from 7 and 35, and that these occur regardless of distance along the transect, land use, topography, soils, or rates of urban growth. This suggests a geometry of fragmentation that may be consistent, and indicates that quantification of both land use and land-use change in zones of fragmentation is potentially important in planning. © 2017 by the authors.
