Interfacing knowledge systems, resilience, cross-cultural research and management, participation, governance, futures
National partnerships of science and matauranga Maori (Maori knowledge, ‘ethnoscience’) for improved environmental management are sought by MoRST’s Vision Matauranga strategic plan to secure the government’s high-level goals of economic prosperity, national identity, and sustainability. Although concrete models of effective dialogue between matauranga and science are gradually emerging, there has been protracted and acrimonious public debate about whose knowledge system knows best how to secure sustainable customary and commercial exploitation of fish and other wild foods. There are few case studies where hard science and detailed, reliable recordings of matauranga (internationally called ‘Traditional Ecological Knowledge’) are put alongside one another to challenge and strengthen each other either in New Zealand or internationally.
Our UORG research uses computer modelling and population ecology to predict the relative harvest impact of harvesting when traditional harvesting tikanga is and is not applied. The basic questions under long-term test are therefore: (i) Does traditional Maori harvest management tikanga promote sustainability of harvesting of taonga species? and (ii) Are current fisheries management rules likely to secure sustainable fishing by commercial, recreational, and customary fishers?
Preliminary models were used to debate and conceptualise how the social-ecological models operate in two harvest systems: titi [muttonbird, Puffinus griseus] and kina [sea urchin, Evechinus chloroticus]. Our emerging meta-analysis of matauranga constructs identified two main aspects of traditional harvest management: (a) traditional tikanga that protects the adults and large size classes is paramount for harvest sustainability, and (b) seasonal rahui (harvest bans) promote escapement and population resilience.
Our research and strategic goals are to:
