High-resolution satellite imagery permits verification of human rights land clearance violations across international borders as a result of unstable regimes or socioeconomic upheaval. Without direct access to these areas to validate allegations of human rights abuse, the use of remote sensing tools, techniques, and data is extremely important. Humanitarian assessment can benefit from software-based solutions, involving radiometrically calibrated normalized difference vegetation index and temporal change imagery. We discuss the introduction of a matrix filter approach for change detection studies to help assist rapid building detection over large search areas against a bright background to evaluate internally displaced people in the 2005 Porta Farm Zimbabwe clearances. Future wide-scale near real-time space-based monitoring with a range of digital filters would be of great benefit to international human rights observers and human rights networks.

“…It is expected economic globalization and climate change-related pressures will increase both the frequency and severity of regional ethnic, resource motivated conflict, with pressures placed upon critical infrastructure [1]. From my research with civilian NGOs, UK Armed Forces, and the littoral capabilities of foreign navies, I have looked at such impacts on civilian conflict actors, in the context of environmental land management, and resources, documenting, and providing, baseline data to help mitigate similar future events [2]. Such data also supports initiatives from the coastal monitoring of illegal fishing with maritime drones, to anti-piracy operations in the littoral environment [3].…”

This paper reviews the growing importance of satellite imagery to provide Normalized Difference Vegetative Index (NDVI) maps, relevant to environmental land management assessment, in the context of resource and climate-related conflict based upon our own humanitarian project-related support. Near real-time space-based monitoring benefits land assessment, human rights observers, and Non-Governmental Organizations (NGOs), in the presence of unstable regimes or socio-economic upheaval. Access to areas to validate claims or allegations with remote sensing tools and digital signal processing techniques is now important. Imagery-based assessment can quantify radiometrically calibrated NDVI, with temporal change indices, may evaluate displacement, to land clearances, and provide metrics on land use change. High-resolution satellite imagery can assess the extent of activities such as open cast mining, and dam construction in inaccessible regions, using semi-automatic orientated methods, generating indices at sub-metric levels derived from satellite data in: Red, Green, Blue, and NIR bands. We discuss the background of space-based applications, and the experimental methodology used. Results and discussion arising from a number of recent cases studies, with specific factors used to help with documentation and formulation of land management risk assessment in the context of climate change threats, e.g. wildfire, are considered. Satellite imagery combined with verified ground data sets of geospatial information and map making, allows external verification of ongoing and planned mining, or construction activities, which impact indigenous communities in such remote geographical regions, for example the controversial Ethiopian Gibe III dam. Seasonal and area change dynamics are observed and discussed.

“…The United Nations Commission for Human Rights (UNCHR) states 'the practice of forced evictions constitutes a gross violation of human rights, in particular the right to adequate housing' [4]. The societal implications and a critical overview of the background planning related issues and future implications surrounding Porta Farm is discussed elsewhere [5] We have used recent technological developments in this area, with image processing methods, to observe several regions international human rights concerns in Sudan [6], Burma [6], and Zimbabwe [7], to quantify them, reviewing the challenges in confirming eyewitness allegations vital for effective response. We focus here on quantified land clearance impact at Porta Farm in 2005, one recorded displacement in the 2005 -2006 clearances affecting townships across Zimbabwe.…”

High-resolution satellite imagery permits verification of land clearance violations across borders due to unstable regimes or socio-economic upheaval. Without access to such areas to validate allegations remote sensing tools and techniques use are very important. Imagery-based assessment can quantify radiometrically calibrated normalised difference vegetation index (NDVI) and temporal changes evaluating displacement in the 2005 Porta Farm Zimbabwe clearances. Future nearreal time space-based monitoring would benefit human rights observers and networks.
