Anthropogenic activities and climate change have altered the environment profoundly, and Africa has been more vulnerable due to lack of sustainable mitigation measures in place. The Intergovernmental Panel on Climate Change (IPCC) has reported that the most hazardous manifestation of climate change is through increased temperature, wetter and drier climates, heat waves and prolonged droughts, which in turn causes severe fluctuations in crop and animal production as well as biodiversity loss. Other impacts include land degradation, invasive species spread, pests and diseases proliferation, rangeland quality and quantity losses, among others. In coastal areas, agriculture is affected by inundation due to sea level rise and also salt water intrusion.
The success of environmental management and protection lies in the availability of adequate information to support intervention measures by decision makers. Developments in remote sensing, particularly the recent sensors with high resolution (spatial, spectral and temporal) and freely available creates a great opportunity for Africa to use such data for improved resource management and a stride towards achieving the UN sustainable Development goals (SDG). In order to promote earth observation research in Africa, this theme is dedicated to relevant scientific contributions that addresses environmental problems facing Africa using remote sensing.
The special issue focuses on innovative methods and applications of remote sensing to address a myriad of environmental problems at different spatial scales in Africa. Authors are invited to submit papers on a range of topics, but not limited to:
1. Biomass and rangeland productivity monitoring
2. Forests and resource conservation (Landscape dynamics, ecosystem services, etc.)
3. Alien invasive plant species and bush encroachment
4. Agricultural productivity and food security (crop mapping, yield prediction, pests and diseases, etc.)
5. Hazards and disaster management (Drought, floods, fire, etc.)
6. Urban and peri-urban management
The submitted papers may address topics such as novel sensors, accuracy assessment, scaling issues, methods, integration of microwave (i.e. LiDAR) and optical sensors, UAVs, algorithms or innovative applications of remote sensing related to the aforementioned issues, in the context of Africa.
Papers must be original contributions, not previously published or submitted to other journals. Papers published or submitted for publication in conference proceedings may be considered provided that they are considerably extended and improved. Substantive research and relevant-for-practice papers will be preferred. Review articles around the topics are also encouraged. Papers must follow the instructions for authors at http://www.elsevier.com/journals/isprs-journal-of-photogrammetry-and-remote ensing/0924-2716/guide-for-authors.
All manuscripts must be submitted through the online submission system of
ISPRS Journal of Photogrammetry and Remote Sensing. During the submission process, it must be indicated that the manuscript is intended for this Special Issue by selecting “VSI: African sustainability”.
Manuscript submission will open on 01 Mar 2019
Manuscript submission deadline: 31 Dec 2019
