Integrating the spatial proximity effect into the assessment of changes in ecosystem services for biodiversity conservation

Journal Articles & Books
december, 2016

The assessment of the value of ecosystem services is a valuable tool for biodiversity conservation that can facilitate better environmental policy decision-making and land management, and can help land managers develop interventions to compensate for biodiversity loss at the patch level. Previous studies have suggested that it is appropriate to assess the value of biodiversity for conservation planning by considering both the condition of the landscape and the spatial configuration of adjacent land uses that can be reflected as a proximity effect.

Towards an energy–landscape integrated analysis? Exploring the links between socio-metabolic disturbance and landscape ecology performance (Mallorca, Spain, 1956–2011)

CONTEXT: The role of agricultural landscapes in biodiversity conservation is an emerging topic in a world experiencing a worrying decrease of species richness. Farm systems may either decrease or increase biological diversity, depending on land-use intensities and management. OBJECTIVES: We present an intermediate disturbance-complexity model (IDC) of cultural landscapes aimed at assessing how different levels of anthropogenic disturbance on ecosystems affect the capacity to host biodiversity depending on the land matrix heterogeneity.

Does urbanization increase diurnal land surface temperature variation? Evidence and implications

Journal Articles & Books
december, 2016

The diurnal land surface temperature (LST) variation is a primary characteristic of the effects of urbanization. However, no study to date has focused on changes in diurnal LST variation in urban environments. This paper investigates the effects of urbanization on landscape pattern and diurnal LST variation of Taipei City, using MODIS thermal images and SPOT multispectral remote sensing images over the 1994–2010 period. Supervised land-cover classifications were conducted to investigate decadal land-cover changes within the study area.

Multiple watershed alterations influence fish community structure in Great Plains prairie streams

Journal Articles & Books

United States of America

Stream fish distributions are commonly linked to environmental disturbances affecting terrestrial landscapes. In Great Plains prairie streams, the independent and interactive effects of watershed impoundments and land cover changes remain poorly understood despite their prevalence and assumed contribution to declining stream fish diversity.

Floristic and structural differentiation between gardens of primary and secondary residences in the Costa Brava (Catalonia, Spain)

Journal Articles & Books

Spain

Urban sprawl along the Mediterranean coast is characterized by single-family houses and domestic gardens. Many new residences are secondary homes for socio-demographically diverse tourists. We explore the differences between the residence types in terms of their garden structures and plant compositions using socioeconomic and legacy attributes. Outdoor areas of 245 primary and secondary homes were investigated to determine plant compositions, land cover and household characteristics. Then, the outdoor land cover was compared between the two residence types.

Greenbelts in Germany's regional plans—An effective growth management policy?

Journal Articles & Books
december, 2016
Germany

Greenbelts are the best-known growth management policies in Germany. As part of its regional plans, they attempt to keep undeveloped areas permanently open, thus avoiding sprawling, i.e., land consumptive forms of urban development. However, the effectiveness of such land use designations in terms of guiding and limiting urban growth has rarely been the subject of in-depth research. This is the first study to present a GIS-based analysis of the restrictiveness of greenbelt designations in Germany and their impact on urban spatial structure and land use.

Projecting alternative urban growth patterns: The development and application of a remote sensing assisted calibration framework for the Greater Dublin Area

Journal Articles & Books
december, 2016

Land use change models are powerful tools that allow planners and policy makers to assess the long-term spatial and environmental impacts of their decisions. In order for these models to produce a realistic output, they should be properly calibrated. This is usually achieved by comparing simulated land-use maps of dates in the past to reference land-use maps of a corresponding date. As land-use data are often not readily or frequently available, we propose a two-stage calibration framework that includes existing land-use maps as well as remote sensing derived maps of the urban extent.

influence of rapid urbanization and land use changes on terrestrial carbon sources/sinks in Guangzhou, China

Journal Articles & Books
december, 2016
China

Complex changes in carbon sources and sinks caused by rapid urbanization have been observed with extensive changes in the quantity, structure, and spatial pattern of land use types. Based on the modified Carnegie-Ames-Stanford Approach model and on gray relational analysis, we analyzed the influence of land use changes on carbon sinks and emissions in Guangzhou from 2000 to 2012. The aim was to identify suitable options for built-up land expansion that would allow for minimal carbon losses.

The study aims to assess the market for low and middle income housing finance in Bangladesh and identify the demand trajectory of this segment over the next 4 years. In addition, the report identifies factors that constrain the housing finance from serving low and middle income households.

Co-composting of solid waste and fecal sludge for nutrient and organic matter recovery

Reports & Research
december, 2016

Biological treatment, composting, in particular, is a relatively simple, durable and inexpensive alternative for stabilizing and reducing biodegradable waste. Co-composting of different waste sources allows to enhance the compost nutrient value. In particular, integration of ‘biosolids’ from the sanitation sector as potential input material for co-composting would provide a solution for the much needed treatment of fecal sludge from on-site sanitation systems, and make use of its high nutrient content.

Effect of catchment-scale green roof deployment on stormwater generation and reuse in a tropical city

Singapore

Low-impact development (LID) comprises a broad spectrum of stormwater management technologies for mitigating the impacts of urbanization on hydrological processes. Among these technologies, green roofs are one of the most adopted solutions, especially in densely populated metropolitan areas, where roofs take up a significant portion of the impervious surfaces and land areas are scarce.

Improving water sustainability and food security through increased crop water productivity in Malawi

Journal Articles & Books

Malawi

Agriculture accounts for most of the renewable freshwater resource withdrawals in Malawi, yet food insecurity and water scarcity remain as major challenges. Despite Malawi’s vast water resources, climate change, coupled with increasing population and urbanisation are contributing to increasing water scarcity. Improving crop water productivity has been identified as a possible solution to water and food insecurity, by producing more food with less water, that is, to produce “more crop per drop”.
