The journal Joelho 11&12 is devoted to the crossings of reciprocal lessons in landscape, archaeology and architecture studies. It focuses on the disciplinary intersection and considers studies devoted to a reflection on the sustainability and conservation of peripheral archaeological sites.

It takes into account the great threats involved in abandonment and degradation or that climate change implies (in particular on sites located on the shore of fragile coastline systems subject to collapse, changing seawater levels, river and stream flooding regimes, and forest fires).

It also covers actions concerning the mitigation of threats to heritage (fences and walls, coverage and other protections, inclusion in contemporary developments of archaeological remains; run-off channels; forests, plantations of fire-fighting tree and plant species), tourist pressure on the shoreline and inland desertification (construction of accessible routes, logistic and informational support, cultural uses of archaeological findings), and alternative uses of agricultural intensive soil that may take advantage of other forms of plantations, including millennial fallow.
