The importance of orientation of the block and parcel in land consolidation

Policy Papers & Briefs
Dezembro, 2012
Turquia

The objective of this study was to evaluate response of parcel orientation on crop yield and yield characteristics. The study was carried out on second crop maize in Bafra District of Samsun province in 2001 and 2002 years. The experiment was established at four different directions (east-west, north-south, northeast-southwest and northwest-southeast) containing the plots with 70x12 cm row spacing and row planting distances in three replications.

Green corridors and fragmentation in South Eastern Black Sea coastal landscape

Journal Articles & Books
Dezembro, 2013

Green corridors are inevitable part of land cover and land use planning activities as they affect climate, hydrology and ecology of the urbanized regions. Detection and monitoring of green corridors and their relative functions are very important in terms of landscape management. They also carry information on changing speed from “green to grey” and fragmentation level of the urbanized regions. Analyzing the fragmentation level of the landscape formation reflects the management strategy and overall success of decision makers.

Indicators of nutrients transport from agricultural catchments under temperate climate: A review

Journal Articles & Books
Dezembro, 2012

The flow of chemical materials along spatial elements is a fundamental aspect of landscape ecology. The research renders indicators for water pollution, which are utile for functional water management and land use planning. Ecologists identify mechanisms of nutrients transfer and mitigate their environmental impacts using freshwater wetlands and riparian buffers. In order to estimate the N (nitrogen) and P (phosphorus) loss risk, current research combines indicators into index models.

Spatial modeling of rangeland potential vegetation environments

Journal Articles & Books
Dezembro, 2001

Potential vegetation environments (e.g., habitat types, range sites, ecological sites) are important to land managers because they provide a conceptual basis for the description of resource potentials and ecological integrity. Efficient use of potential vegetation classifications in regional or subregional scale assessments of ecosystem health has been limited to date, however, because traditional ecological unit mapping procedures often treat such classifications as ancillary information in the map unit description.

Predicting the Impacts of Future Sea-Level Rise on an Endangered Lagomorph

Journal Articles & Books
Dezembro, 2007

Human-induced global climate change presents a unique and difficult challenge to the conservation of biodiversity. Despite increasing attention on global climate change, few studies have assessed the projected impacts of sea-level rise to threatened and endangered species. Therefore, we estimated the impacts of rising sea levels on the endangered Lower Keys marsh rabbit (Sylvilagus palustris hefneri) across its geographic distribution under scenarios of current conditions, low (0.3-m), medium (0.6-m), and high (0.9-m) sea-level rise.

Watershed management in an urban setting: process, scale and administration

Journal Articles & Books
Dezembro, 2012
Austrália

Efforts in post-industrial countries to refine environment and planning administration in the face of unprecedented urban growth have important implications for ecological systems and human quality of life. This paper uses the case of an urban riparian corridor in South East Queensland, Australia to contribute to understandings of interactions between land use planning processes, watershed management initiatives and broader administrative structures in urban and rapidly urbanising settings. In particular it examines the understudied application of watershed management to an urban setting.

Three decades of sustainable agricultural systems (SAS) in Sri Lanka: a review of institutional and policy issues

Journal Articles & Books
Dezembro, 2003
Sri Lanka

Many attempts, which were aimed at promoting Sustainable Agricultural Systems (SAS) in Sri Lanka failed due to poor acceptance by farmers. This situation still exists in spite of the formidable scientific evidence that supports the physical effectiveness of these systems to solve the respective problems. Factors that lead to poor acceptance of SAS by farmers can be broadly categorized as system specific factors and general factors that affect all systems commonly.

Simulation of soil carbon changes due to land use change in urban areas in China

Journal Articles & Books
Dezembro, 2013
China

Land use change can have a strong impact on soil carbon dynamics and carbon stocks in urban areas. Due to rapid urbanization, large areas of land have been paved, and other areas have undergone rapid land use change. Evaluation of the impact of urbanization on carbon dynamics and carbon stock (30 cm) has become an issue of urgent concern. The soil carbon dynamics, due to rapid land use change in Tianjin Binhai New Area of China, have been simulated in this paper using the RothC model.

Effects of land use patterns on the diversity and conservation status of butterflies in Kisii highlands, Kenya

Journal Articles & Books
Dezembro, 2015
Quênia

Habitat degradation poses a great threat to biodiversity conservation. Abundance and diversity of butterflies is an indicator of good environmental health. Understanding how different butterfly species respond to habitat degradation is a necessary step towards the development of effective measures to enhance environmental protection. This study investigated the impact of land use patterns on the diversity, abundance, and conservation status of butterflies in the Kisii highlands; a densely-populated region in Kenya that has received little attention in ecological studies.

Indicators for strategic environmental assessment in regional land use planning to assess conflicts with adaptation to global climate change

Journal Articles & Books
Dezembro, 2011

The paper presents the use of indicators in a site-specific assessment method for strategic environmental assessment in regional land use planning (here: SEA-REP). It is explained with the example of the state of environment indicator ‘LUCCA 4—Urban Areas at Risk of Flooding’, how SEA as a decision-aiding instrument can contribute to the prevention of conflicts with policy for adaptation to climate change. The method begins with the determination of impact factors for SEA.
