Desertification, currently managed through a regime of administrative translation, reduces the planetary crisis of land degradation to a standardised set of metrics with the complex, non-linear systems flattened into actionable data for the state actors.
Definitions and indices (such as NDVI) do not merely measure the desert, but actively construct an image of it with binary logics. This, in turn, dictates top-down interventions that often prioritise the appearance of successes catered to the metrics used, overlooking the robustness of the intervention itself.
To move beyond this, requires the establishment of a critical distinction between primary (geological) and secondary (anthropogenic) deserts. Analysing deserts through geological, hydrological, aeolian, ecological, radiative, and social cycles, one can identify nuances that can be used to avoid misidentifying stable primary deserts for desertifying or desertified secondary deserts. It also becomes possible to examine successful precedents through how they work with these cycles to distill a strategy for combating desertification specifically within anthropogenic arid and semi-arid zones, so as not to launch indiscriminate ‘green wars’.
With this, it is then also possible to create a technical proposal for a multi-scalar monitoring framework. Recognising the ‘blurring’ effect of current satellite resolutions, this framework proposed integrates the orbital view with a ground-based sensor network to fill in the sub-pixel gaps. This creates a feedback loop both states and communities can participate in, helping them interpret environmental rhythms and act on them in real-time.
Ultimately, the aim is to design a system where remote sensing is not just a tool for administrative flattening, but also a medium for ecological reconciliation. By increasing the capacity to perceive and interpret the pulse of a territory, the proposed framework enables precise, rhythmic interventions allowing for engagement with the desert’s metabolic flows rather than simply extracting from its reserves.
