Special Issue Information

Dear Colleagues,

In the absence of established in-situ monitoring networks, remote sensing has become an important tool for environmental managers in the Global South to monitor and model changes in the environment across a broad range of sectors, such as water and natural resource management, hazard and disaster management and conservation. In these contexts, remote sensing technologies and data can help with the detection, monitoring and forecasting of environmental changes to inform decision-making and sustainable environmental management.

This Special Issue aims to report on the applications of remote sensing and spatial analysis for environmental management in the Global South. We welcome empirical research articles and review papers which explore how remote sensing data can help monitor and model environmental change across a broad range of scales, from national/regional investigations utilizing low-medium resolution satellite data to local-scale and high-resolution analyses. We welcome manuscripts exploring all aspects of applied spatial analysis and environmental remote sensing in the Global South, particularly the ones which explicitly discuss how remote sensing can be used for environmental management.

  • Applications of environmental remote sensing and spatial analysis in the Global South;
  • How remote sensing and spatial analysis can support environmental management;
  • Evaluating environmental change over time;
  • Evaluating the impact of environmental management initiatives and projects;
  • Monitoring changes in natural resource availability (including water resources, forest resources, agricultural resources, geological resources, etc.);
  • How remote sensing can support environmental hazard and disaster monitoring, modelling, and management;
  • Comparison of remote sensing data sources and methodologies for environmental management;
  • New remote sensing data and methodologies for monitoring the environment.

With few measurement sites and a great need to validate satellite data to characterize the exchange of energy and carbon fluxes in tropical forest areas, quantified by the Net Ecosystem Exchange (NEE) and associated with phenological measurements, there is an increasing need for studies aimed at characterizing the Amazonian environment in its biosphere–atmosphere interaction, considering the accelerated deforestation in recent years. Using data from a flux measurement tower in the Caxiuanã-PA forest (2005–2008), climatic data, CO2 exchange estimated by eddy covariance, as well as Gross Primary Productivity (GPP) data and satellite vegetation indices (from MODIS), this work aimed to describe the site’s energy, climatic and carbon cycle flux patterns, correlating its gross primary productivity with satellite vegetation indices. The results found were: (1) marked seasonality of climatic variables and energy flows, with evapotranspiration and air temperature on the site following the annual march of solar radiation and precipitation; (2) energy fluxes in phase and dependent on available energy; (3) the site as a carbon sink (−569.7 ± 444.9 gC m−2 year−1), with intensity varying according to the site’s annual water availability; (4) low correlation between productivity data and vegetation indices, corroborating data in the literature on these variables in this type of ecosystem. The results show the importance of preserving this type of environment for the mitigation of global warming and the need to improve satellite estimates for this region. NDVI and EVI patterns follow radiative availability, as does LAI, but without direct capture related to GPP data, which correlates better with satellite data only in the months with the highest LAI. The results show the significant difference at a point measurement to a satellite interpolation, presenting how important preserving any type of environment is, even related to its size, for the global climate balance, and also the need to improve satellite estimates for smaller areas.

Hydrological Ecosystem Services (HES) are crucial components of environmental sustainability and provide indispensable benefits. The present study identifies critical hot and cold spots areas of HES in the Aglar watershed of the Indian Himalayan Region using six HES descriptors, namely water yield (WYLD), crop yield factor (CYF), sediment yield (SYLD), base flow (LATQ), surface runoff (SURFQ), and total water retention (TWR). The analysis was conducted using weightage-based approaches under two methods: (1) evaluating six HES descriptors individually and (2) grouping them into broad ecosystem service categories. Furthermore, the study assessed pixel-level uncertainties that arose because of the distinctive methods used in the identification of hot and cold spots. The associated synergies and trade-offs among HES descriptors were examined too. From method 1, 0.26% area of the watershed was classified as cold spots and 3.18% as hot spots, whereas method 2 classified 2.42% area as cold spots and 2.36% as hot spots. Pixel-level uncertainties showed that 0.57 km2 and 6.86 km2 of the watershed were consistently under cold and hot spots, respectively, using method 1, whereas method 2 identified 2.30 km2 and 6.97 km2 as cold spots and hot spots, respectively. The spatial analysis of hot spots showed consistent patterns in certain parts of the watershed, primarily in the south to southwest region, while cold spots were mainly found on the eastern side. Upon analyzing HES descriptors within broad ecosystem service categories, hot spots were mainly in the southern part, and cold spots were scattered throughout the watershed, especially in agricultural and scrubland areas. The significant synergistic relation between LATQ and WYLD, and sediment retention and WYLD and trade-offs between SURFQ and HES descriptors like WYLD, LATQ, sediment retention, and TWR was attributed to varying factors such as land use and topography impacting the water balance components in the watershed. The findings underscore the critical need for targeted conservation efforts to maintain the ecologically sensitive regions at watershed scale. Full article

Abstract: Hydrological Ecosystem Services (HES) are crucial components of environmental sustainability and provide indispensable benefits. The present study identifies critical hot and cold spots areas of HES in Aglar watershed of Indian Himalayan Region using six HES descriptors namely Water Yield (WYLD), Crop Yield Factor (CYF), Sediment Retention (SR), Base Flow (LATQ), Surface Runoff (SURQ), and Total Water Retention (TWR). The analysis was conducted using weightage-based approaches under two methods: (1) evaluating six HES descriptors individually, and (2) grouping them into broad ecosystem service categories. Furthermore, the study assessed pixel-level uncertainties arose because of distinctive methods used in identification of hot and cold spots. Associated synergies and trade-offs among HES descriptors were examined too. From method 1, 0.3% area of the watershed was classified as cold spots and 3.19% as hot spots whereas method 2 classified 2.44% area as cold spots and 2.34% as hot spots. Pixel-level uncertainties showed that 0.57 km² and 6.86 km² of the watershed were consistently under cold and hot spots, respectively, using method 1, whereas method 2 identified 2.30 km² and 6.97 km² as cold spots and hot spots, respectively. The spatial analysis of hot spots showed consistent patterns in certain parts of the watershed, primarily in the south to southwest region, while cold spots were mainly found on the eastern side. Upon analyzing HES descriptors within broad ecosystem service categories, hot spots were mainly in the southern part, and cold spots were scattered throughout the watershed, especially in agricultural and scrubland areas. Significant synergistic relation between LATQ and WYLD, and SYLD and WYLD and tradeoffs between SURQ and HES descriptors like WYLD, LATQ, SYLD, and TWR was attributed to varying factors such as land use and topography impacting the water-balance components in the watershed. The findings underscore the critical need for targeted conservation efforts to maintain the ecologically sensitive regions at watershed scale.
