“…We created three categories of FE metrics inspired by landscape ecology. These metrics are typically used to describe ecological processes such as food foraging behavior or predator-prey relationships ( Costanza et al, 2019 ; Gergel and Turner, 2017 ; Turner et al, 2001 ). Landscape ecology metrics can either address the landscape-level or the patch-level, i.e.…”

We study the relationship between the food environment (FE) and the food purchase patterns, dietary intakes, and nutritional status of individuals in peri-urban Tanzania. In Africa, the prevailing high density of informal vendors creates challenges to characterizing the FE. We present a protocol and tool developed as part of the Diet, Environment, and Choices of positive living (DECIDE) study to measure characteristics of the FE. We mapped 6627 food vendors in a peri-urban settlement of Dar es Salaam, of which over 60% were semi-formal and informal (mobile) vendors. We compute and compare four FE metrics inspired by landscape ecology—density, dispersion, diversity, and dominance—to better understand how the informal food environment relates to food purchase patterns, diets, and nutritional status among households with persons living with human immunodeficiency virus (PLHIV).

“…Following this attempt to approach the Sines landscape dynamics and while novel tools and insights emerge, further developments for the present case study are expected. Topics related with measuring patterns, such as identifying hotspots for conservation and informed conservation strategies (Costanza et al 2019), or other processes outcomes (e.g., ecosystem services), including a broader regional context, will contribute to a better understanding of landscape connectivity and habitat fragmentation. These aspects are crucial in the context of landscape sustainable management.…”

The Atlantic maritime winds and waves, as natural forces, shaped the physiography of Sines, a peculiar rocky cliff cape at the western Portuguese coast, as well as cultural processes have shaped its spatial arrangement since ancient times. Despite its small size, Sines port has always been an important maritime trade corner. In the 1970s, winds and waves of modernity reached the Sines coast with an imposing industrial-port complex. We present the history of Sines cape focusing on its landscape dynamics. The patch-corridor-matrix model allowed us to describe the mosaic transformation of such a unique landscape. Spatial information was gathered mostly from historical maps processed with digital tools. A time series of thematic maps (landscape mosaic pattern) was obtained, covering more than 120 years. Current results emphasize that this landscape underwent relevant transformations related to human activities since former times, although disturbance and fragmentation of the landscape were strongly intensified after the arrival of the post-modern wave of the industrial culture. The present study provides a contribution to the history of the Portuguese and Mediterranean coastal landscapes; and results could be used to support decision making in sustainable management of this territory.

“…There have also been major developments over the past century in approaches to quantify landscape structure and measure forest fragmentation. These approaches have drawn on evolving knowledge in a diverse variety of fields, including classical ecology, network theory and fractal geometry [11]. However, there are differences in the ways that fragmentation is measured, making direct comparisons between studies difficult.…”

Spatial Analysis of the Drivers, Characteristics, and Effects of Forest Fragmentation

Building on the existing literature, this study examines whether specific drivers of forest fragmentation cause particular fragmentation characteristics, and how these characteristics can be linked to their effects on forest-dwelling species. This research uses Landsat remote imaging to examine the changing patterns of forests. It focuses on areas which have undergone a high level of a specific fragmentation driver, in particular either agricultural expansion or commodity-driven deforestation. Seven municipalities in the states of Rondônia and Mato Grosso in Brazil are selected as case study areas, as these states experienced a high level of commodity-driven deforestation and agricultural expansion respectively. Land cover maps of each municipality are created using the Geographical Information System software ArcGIS Spatial Analyst extension. The resulting categorical maps are input into Fragstats fragmentation software to calculate quantifiable fragmentation metrics for each municipality. To determine the effects that these characteristics are likely to cause, this study uses a literature review to determine how species traits affect their responses to forest fragmentation. Results indicate that, in areas that underwent agricultural expansion, the remaining forest patches became more complex in shape with longer edges and lost a large amount of core area. This negatively affects species which are either highly dispersive or specialist to core forest habitat. In areas that underwent commodity-driven deforestation, it was more likely that forest patches would become less aggregated and create disjunct core areas. This negatively affects smaller, sedentary animals which do not naturally travel long distances. This study is significant in that it links individual fragmentation drivers to their landscape characteristics, and in turn uses these to predict effects on species with particular traits. This information will prove useful for forest managers, particularly in the case study municipalities examined in this study, in deciding which species require further protection measures. The methodology could be applied to other drivers of forest fragmentation such as forest fires.
