: Some studies have established relationships between neighborhood conditions and health. However, they neither evaluate the relative importance of neighborhood components in increasing obesity nor, more crucially, how these neighborhood factors vary geographically. We use the geographical random forest to analyze each factor’s spatial variation an...

The aim of this paper is to present developments of an advanced geospatial analytics algorithm that improves the prediction power of a random forest regression model while addressing the issue of spatial dependence commonly found in geographical data. We applied the methodology to a simple model of mean household income in the European Union region...

Mediterranean islands are characterized by high biodiversity and cultural value. As the human demand for natural resources increases, the need for assessing the future landscape is prerequisite. This study aimed to simulate the future landscape composition and structure of the Ionian Islands (Western Greece). To do so, we integrated the Future Land...

Mediterranean islands are widely recognized as biodiversity hotspots, with a long history of human activities shaping multi-functional landscapes. Socioeconomic and environmental factors are among the most important factors driving the creation of diverse landscapes, with a high supply of ecosystem services (ES). However, these factors, along with...

By accounting for both the supply and demand of ecosystem services (ES), it is possible to identify where ES are not able to satisfy human needs. In addition, human demands for natural resources continue to grow rapidly, risking the short supply of ES. Consequently, understanding the balance between ES supply and demand can facilitate sustainable s...

Mediterranean islands are heterogeneous and dynamic landscapes resulting from complex interactions between natural and anthropogenic processes that contribute to their high biodiversity, and aesthetic and cultural value. Such islands are considered susceptible to environmental changes that, in combination with intense human activities, could harm l...

In this paper we investigate a local implementation of Random Forest (RF), named Geographical Random Forest (GRF) to predict population density with Very-High-Resolution Remote Sensing (VHHRS) data. As an independent variable we use population density at the neighborhood level from the 2013 census of Dakar, while as explanatory features, the propor...

Implements a spatial extension of the random forest algorithm (Georganos et al. (2019) doi:10.1080/10106049.2019.1595177). Future updates include more local machine learning methods as well as a geographically weighted random forest.

Machine learning algorithms such as Random Forest (RF) are being increasingly applied on traditionally geographical topics such as population estimation. Even though RF is a well performing and generalizable algorithm, the vast majority of its implementations are still 'aspatial' and may not address spatial heterogenous processes. At the same time,...

To manage multiple ecosystem services (ES) effectively, it is essential to understand how the dynamics of ES maintain healthy ecosystems to avoid potential negative impacts on human well-being in the context of sustainable development. In particular, the Ionian Islands in the central Mediterranean are characterized by high natural, ecological, and...

The book aims to assist students and researchers to learn how to apply spatial data analysis methods to real-world data using an open source statistical programming language.

Mediterranean islands contain heterogeneous landscapes, resulting from the complex interactions between natural and anthropogenic processes, and have significant ecological and conservation importance. They are vulnerable systems to global change and the monitoring of changes, induced by the interacting environmental drivers, is of particular impor...

The best way to communicate information about phenomena and human behaviour is by visual means (image or video). The information about various locations are better represented by a map. This is because the reader cannot easily follow data on tables and text. On the contrary, our vision allows us to quickly identify information and patterns on maps....

The principal objective of this study is to develop a gravity model for the spatial interaction analysis of international trade flows.

Tak...

Land cover/use changes mainly occur due to human activities and natural processes. Over the last decades, human activities have been intensified in result of significant changes of ecosystems, such as environmental degradation and landscape fragmentation. The study of these changes is considered as one of the main environmental and social issues wo...

People depend on ecosystems and their services for food, climate regulation, aesthetic pleasure, recreation-entertainment etc. Ecosystem services (ES) are defined as benefits provided to humans from the environment and are crucial in the search for sustainability. In order to identify synergies and trade-offs between ES at the Ionian Islands, 9 ES...
