“…Remote sensing, thus, is an immense and potential tool to study changes in land cover, forest density, and biodiversity, even in inaccessible or remote places. Moreover, the integrated use of remotely sensed data, GPS, and GIS will assist consultants, natural resource managers, and researchers in agencies and conservation institutions to develop management plans for various natural resources (Philipson and Lindell, 2003;ESRI, 2024).…”

Environmental and land resource degradation is a serious problem that poses significant challenges in Sudan and worldwide generally. Despite the fact that the physical environment components are the underlying economic resources and production assets in developing countries like Sudan, and they directly affect the nation’s socioeconomic aspects of income, health, water availability, food security, and many others. The interventions and protective measures were insufficient to meet the magnitude and extent of the ongoing degradation and resource wastage. Based on the analysis of the indicators and trends of the environmental and natural resources management ‘status quo’, this paper is an attempt to overview and investigate the state of environmental and natural resources management and governance in Sudan. Further discussion delves into the utilization of geo-information systems in Sudan’s environmental and resource management by analyzing and reviewing “some previous case studies” where GIS approaches and techniques were deployed. The paper further strives to explore and highlight the opportunities and potential contributions of GIS in the context of Sudan’s environmental and resource management. Lessons learned from the previous experiences were considered, and the recommendations for the future use of a tailored geo-information system in Sudan context were highlighted and suggested to support better practices and sustainability insights for environmental governance and resources management.

“…The need for update information has long been recognized and stimulated the use of earth data using remote sensing techniques, which has become a universal and familiar instrument for assessing natural resources (Philipson, Lindell, 2003). Information from low-altitude satellite sensors and remote sensing offer an optimal path for understanding pattern and process related to rangeland condition in the area.…”

Using species distribution modelling to guide survey efforts of the Snow Leopard (Panthera uncia) in the Central Kyrgyz Ala-Too region. -V. Tytar, T. Asykulov, M. Hammer. -Listed as Vulnerable (IUCN 2017), the snow leopard is declining across much of its present range. One of the major reasons for the snow leopard population decline in the last two decades is a reduction in large prey species that are the cornerstone of the conservation of the snow leopard; in the Central Kyrgyz Ala-Too region such species is primarily the Siberian ibex (Capra sibirica). Understanding factors affecting basic requirement of ibex and shaping its distribution is essential for protecting the prey species snow leopards rely on the most. Using a niche modelling approach we explored which environmental features are best associated with ibex occurrence, how well do models predict ibex occurrence, and does the potential distribution of highly suitable ibex habitat correlate with records of snow leopard. A PC analysis was used to capture aspects of ibex ecology and niche. Results of such analysis agree with the herbivore character of the species and bioclimatic habitat requirements of the vegetation it feeds upon, richer in flatter areas, and where plants may benefit from more sunlight. The niche model based on maximum entropy (Maxent) had "useful" discrimination abilities (AUC = 0.746), enabling to produce a map, where a contour line is drawn around areas of highly predicted probability (> 0.5) of ibex occurrence. In terms of nature conservation planning and setting snow leopard research priorities these areas represent the most interest. With one outlier, most of snow leopard records made in the study area (n = 15) fell within the 10 percentile presence threshold (0.368). Predicted probability of ibex occurrence in places where records were made of snow leopard presence (pugmarks, scrapes etc.) was 0.559 expectedly suggesting areas of high ibex habitat suitability attract the predator.

“…an increase or decrease in vegetation index value). Change detection analysis is used in a wide range of applications, including urban development (Zhang et al 2002, Yang et al 2003, Cova et al 2004, coral reef monitoring (Palandro et al 2003, Philipson and Lindell 2003, Elvidge et al 2004) and disaster management in response to both natural events, such as landslides (Cheng et al 2004, Lin et al 2005, Nichol and Wong 2005, and anthropogenic events, such as armed conflicts (Abuelgasim et al 1999, Al-Khudhairy et al 2005. Various change detection techniques have been employed successfully using remotely sensed imagery (Singh 1989, Coppin et al 2004.…”

Natural and anthropogenic processes at the Earth's surface operate at a range of spatial and temporal scales. Different scales of observation are required to match the spatial scales of the processes under observation. At the same time, the temporal sampling rate of the observing systems must be reconciled with the dynamics of the processes observed. Bringing together these issues requires insight, innovation and, inevitably, compromise. This paper reviews spatial and temporal considerations in remote sensing and introduces the papers in this Special Issue on 'Scales and Dynamics in Observing the Environment'. The review comprises three main sections. The first section focuses on spatial variability in remote sensing, while the second section focuses on temporal variability in remote sensing. The third section links these two issues, focusing on the interplay of space and time in remote sensing. The review is primarily theoretical, explaining spatial and temporal properties of remote sensing and remotely sensed phenomena. Where appropriate, however, practical examples are included to demonstrate how remote sensing is used in environmental applications. Following the review, the papers included in the Special Issue are introduced, outlining their significance in the context of 'Scales and Dynamics in Observing the Environment'.
