“…Though its first applications in the field of climate change were in the context of the global negotiations (Ramanathan 1998) and mitigation policy instruments (Konidari and Mavrakis 2007), AHP has been used increasingly in the field of climate adaptation (Sposito 2006;Yin et al 2008). In the present study, pairwise comparison was implemented in two stages.…”

Climate change is already affecting many natural systems and human environments worldwide, like the semiarid Guadiana Basin in Spain. This paper illustrates a systematic analysis of climate change adaptation in the Guadiana irrigation farming region. The study applies a solution-oriented diagnostic framework structured along a series of sequential analytical steps. An initial stage integrates economic and hydrologic modeling to evaluate the effects of climate change on the agriculture and water sectors. Next, adaptation measures are identified and prioritized through a stakeholder-based multi-criteria analysis.Finally, a social network analysis identifies key actors and their relationships in climate change adaptation. The study shows that under a severe climate change scenario, water availability could be substantially decreased and drought occurrence will augment. In consequence, farmers will adapt their crops to a lesser amount of water and income gains will diminish, particularly for smallholder farms. Among the various adaptation measures considered, those related to private farming (new crop varieties and modern irrigation technologies) are ranked highest, whereas publicfunded hard measures (reservoirs) are lowest and public soft measures (insurance) are ranked middle. In addition, stakeholders highlighted that the most relevant criteria for selecting adaptation plans are environmental protection, financial feasibility and employment creation. Nonetheless, the social network analysis evidenced the need to strengthen the links among the different stakeholder groups to facilitate the implementation of adaptation processes. In sum, the diagnostic framework applied in this research can be considered a valuable tool for guiding and supporting decision making in climate change adaptation and communicating scientific results.

This paper reports on two models that have been developed using ArcView Model Builder to map suitability for agricultural and urban land uses. Both models use a GIS-based multiple criteria modelling approach combining empirical data with experts' judgement.The Agricultural Suitability Model considers soil, landscape and climate criteria; whereas the Urban Buildability Model assesses biophysical, socio-economic and spatial phenomena to define locational suitability from a sustainable development perspective.These models have been used to help develop strategic development plans for several rural shires in Victoria, Australia. One of the major objectives of these Shire development strategies was to protect good agricultural land from urban development. There are more than 30 agricultural land suitability models that have been developed to address particular commodities of interest to these Shires. Shires where these models have been applied so far include South Gippsland.
