  The emerging field of morphogenetic engineering proposes to design complex
heterogeneous system focused on the paradigm of emergence. Necessarily at the
interface of disciplines, its concepts can be defined through multiple
viewpoints. This contribution aims at linking a co-evolutionary perspective on
such systems with morphogenesis, and therein at bringing a novel conceptual
approach to the bottom-up design of complex systems which allows to fully
consider co-evolutive processes. We first situate systems of interest at the
interface between biological and social systems, and introduce a
multidisciplinary perspective on co-evolution. Building on Holland's signals
and boundaries theory of complex adaptive systems, we finally suggest that
morphogenetic systems are equivalent to combinations of co-evolutionary niches.
This introduces an entry to morphogenetic engineering focused on co-evolution
between components of a system. Applications can be found in a broad range of
subjects, which we illustrate with the example of planning in territorial
systems, suggesting an extended scope for the relevance of morphogenetic
engineering concepts.
