Since the opening of Earth Observation (EO) archives (USGS/NASA Landsat and EC/ESA Sentinels), large collections EO data are freely available, offering scientists new possibilities to better understand quantify environmental changes. Fully exploiting these satellite will require approaches for their acquisition, management, distribution, analysis. Given rapid changes emergence big data, innovative solutions needed support policy frameworks related actions toward sustainable development. Here...
Woodlands and savannahs provide essential ecosystem functions services to communities. On the African continent, they are widely utilized converted subsistence intensive agriculture or urbanized. This study investigates changes in land cover over four administrative regions of North Eastern Namibia within Kalahari woodland savannah biome, covering a total 107,994 km2. Land is mapped using multi-sensor Landsat imagery at decadal intervals from 1975 2014, with post-classification change...
Shorebirds have declined severely across the East Asian—Australasian Flyway. Many species rely on intertidal habitats for foraging, yet distribution and conservation status of these Australia remain poorly understood. Here, we utilised freely available satellite imagery to produce first map Australia. We estimated a minimum area 9856 km2, with Queensland Western supporting largest areas. Thirty-nine percent were protected in Australia, some primarily within marine areas (e.g. Queensland)...
Initiatives to promote community-based natural resource management (CBNRM) have been evaluated with mixed results in socio-economic and ecological outcome dimensions. In Namibia, community conservancies are being established since the 1990s mainly reconcile wildlife conservation rural development. As Namibia gears up for participation Reducing Emissions from Deforestation Forest Degradation (REDD+), land use cover change related biomass carbon dynamics may become increasingly important...
Maps that accurately quantify aboveground vegetation biomass (AGB) are essential for ecosystem monitoring and conservation. Throughout Namibia, four change processes widespread, namely, deforestation, woodland degradation, the encroachment of herbaceous grassy layers by woody strata (woody thickening), regrowth. All these affect a range key services, yet their spatial temporal dynamics contributions to AGB remain poorly understood. This study quantifies associated with different over an...
Remnant West African forest patches provide crucial ecosystem functions and services while contributing to sustaining the livelihoods of vast numbers people. The majority lie outside protected areas, although relatively few are managed as sacred forests, which limits their access use. This lack protection, together with a growing demand for arable land resources, have accentuated fragmentation, degradation, deforestation. There is therefore an urgent need generate knowledge on...
Summary In West Africa, vast areas are being deforested; the remnant forest patches provide a wealth of ecosystem services and biodiversity conservation potential, yet they threatened by human activity. Forest <100 ha have not been widely catalogued before; we mapped loss small outside protected in Guinean savannah humid Guineo-Congolian bioclimatic regions Togo, Benin, Nigeria Cameroon between 2000 2022. Focusing on dynamics patches, without considering splitting process larger...
The rate of tropical deforestation is increasing globally, and the fragmentation remaining forests particularly high in arable landscapes West Africa. As such, there an urgent need to map monitor these remnant forest patches/fragments so identify their multiple benefits values. Indeed, recognizing existence will help ensure continued provision ecosystem services while facilitating conservation sustainable use. aim this study therefore inventory characterise current extent change patches...
Abstract. Woody vegetation is an integral component of savannas. Here, two main change processes alter woody vegetation, namely shrub encroachment and deforestation. Both impact a range ecosystem services functions across scales. Accurate estimates change, including spatial extent, rate drivers are lacking. This primarily due to savanna comprising herbaceous each which exhibit divergent phenological characteristics, vary importantly in their response climatic environmental factors. study...
Abstract The rapidly collapsing glacial systems of the Alps produced a large number melt-water lakes and mires after Last Glacial Maximum (LGM) in Late period. Rhone-Aare-glacier system gave rise to moorlands region Three Lakes Region Western Switzerland. When are formed, they efficient sinks atmospheric carbon, but when transformed agricultural land significant C sources. In addition, can be used as archives for reconstructing landscape evolution. We explored more detail dynamics with...
