The Brazilian Geodesign platform was proposed based on extensive experience in Geodesign workshops, aiming to adapt the method to the country’s cultural specificities, with a commitment to support the construction of opinions in planning, in the process of transformative-learning planning. To test the scalability of the method, a study was developed in 13 metropolitan regions of the country, with the involvement of universities, distributed from north to south, in different biomes and urbanization conditions. The same method was proposed for everyone, starting from the same collection of 40 thematic maps to support discussions about alternative futures in land use. Participants used the GISColab platform and went through the same stages of analysis, proposition, and negotiation of ideas. As a result, there was an improvement in the projects developed between the first and the last day of work, with the expansion of compliance with the goals of sustainable development (SDG) and areas for carbon credit. It was possible to observe that, although they used the same framework proposed, each group adapted the method to their local reality, proving the scalability of the process and the necessary flexibility for employment in different realities, ensuring a defensible and reproducible criterion. As recommendations, it would be interesting to apply the same study of multiple simultaneous cases in another country, to analyze the scalability and flexibility to local changes, as it happened in the experiment. This would be entirely possible, as the platform is based on worldwide OGC standards (Open Geospatial Consortium) and would have full interoperability in use.

Abstract. This paper discusses the state of the art in Geodesign, as a result from the evolution in the use of geospatial data for shared and co-creative planning. The evolution of Geographic Information Systems (GIS) led to significant advances in geovisualization, the use of cartographic data via the Internet and the construction of SDIs (Spatial Data Infrastructures). These advances fostered the emergence of Geodesign as one of the foundations for territorial planning. The text will also introduce a Brazilian Geodesign platform, GISColab, developed according to the standards set by the Open Geospatial Consortium (OGC). The platform introduces layer creation resources via WPS (Web Processing Service), as well as tools for measuring the performance of participatory planning workshops, presently focusing on the UN’s Sustainable Development Goals (SDGs). We introduce case studies in which SDGs were explored in different ways: in post-workshop analyses conducted by coordinators and participants, as well as its application as a supportive tool for decision-making during the workshop, via WPS. Finally, we also discuss the inclusion of SDGs to raise awareness of its key themes and support opinion building, resulting in transformative learning experiences.

Maps or remote sensing can be interpreted as the process of reading using various sensors where data collected remotely can be analyzed to obtain information about the object, area or phenomenon. In this study, the author develops a flood disaster mapping information system applying overlays with scoring between the parameters. The determinant factors to provide flood hazard levels includes rainfall factors in the dasarian unit, land-use factors and land-use arbitrary factors. Of all these parameters, a scoring process will be carried out by assigning weights and values according to their respective classifications, then an overlay process will be performed using ArcGIS software. The author conducted this study in Nagan Raya Regency since this area experiences flooding annually.  Framing a thematic map of flood-prone areas in Nagan Raya Regency was designed using the flood hazard method. Spatial data that has been presented in the form of thematic maps as parameters are land use maps, landform maps, and dasarian rainfall maps (per 10 daily). The design of thematic maps that are prone to flooding is done by overlapping (overlay process). In contrast, the determination of the classification is done by adding scores to each parameter, with low, medium and high hazard levels. Parameter analysis shows the level of flood vulnerability in Nagan Raya Regency of each district, namely Beutong: high 0.21%, medium 13.68%, low 86.12%. Seunagan District: high 51.17%, medium 48.83%, low 0%. Seunagan Timur District: high 10.07%, medium 46.18%, low 43.75%. Kuala Subdistrict: high 29.66%, medium 68.99%, low 1.35%. Darul Makmur District: high 8.57%, medium 63.37%, low 28.06%. From the overall results of the study, it can be concluded that the danger of flooding in Nagan Raya Regency with a level of vulnerability: high 9.92%, moderate 42.65% and low 47.43%.

As one of the 17 Sustainable Development Goals, it is sensible to analysis historical urban land use characteristics and project the potentials of urban sustainable development for a smart city. The cellular automaton (CA) model is the widely applied in simulating urban growth, but the optimum parameters of variables driving urban growth in the model remains to be continued to improve. We propose a novel model integrating an artificial fish swarm algorithm (AFSA) and CA for optimizing parameters of variables in the urban growth model and make a comparison between AFSA-CA and other five models, which is used to study a 40-year urban land growth of Wuhan. We found that the urban growth types from 1995 to 2015 appeared relatively consistent, mainly including infilling, edge-expansion and distant-leap types in Wuhan, which a certain range of urban land growth on the periphery of the central area. Additionally, although the genetic algorithms (GA)-CA model and the AFSA-CA model among the six models due to the distance variables, the parameter value of the GA-CA model is −15.5409 according to the fact that the population (POP) variable should be positively. As a result, the AFSA-CA model regardless of the initial parameter setting is superior to the GA-CA model and the GA-CA model is superior to all the other models. Finally, it is projected that the potentials of urban growth in Wuhan for 2025 and 2035 under three scenarios (natural urban land growth without any restrictions (NULG), sustainable urban land growth with cropland protection and ecological security (SULG), and economic urban land growth with sustainable development and economic development in the core area (EULG)) focus mainly on existing urban land and some new town centers based on AFSA-CA urban growth simulation model. An increasingly precise simulation can determine the potential increase area and quantity of urban land, providing a basis to judge the layout of urban land use for urban planners.

The implementation of ecological projects can largely change regional land use patterns, in turn altering the local hydrological process. Articulating these changes and their effects on ecosystem services, such as water conservation, is critical to understanding the impacts of land use activities and in directing future land planning toward regional sustainable development. Taking Zhangjiakou City of the Yongding River as the study area—a region with implementation of various ecological projects—the impact of land use changes on various hydrological components and water conservation capacity from 2000 to 2015 was simulated based on a soil and water assessment tool model (SWAT). An empirical regression model based on partial least squares was established to explore the contribution of different land use changes on water conservation. With special focus on the forest having the most complex effects on the hydrological process, the impacts of forest type and age on the water conservation capacity are discussed on different scales. Results show that between 2000 and 2015, the area of forest, grassland and cultivated land decreased by 0.05%, 0.98% and 1.64%, respectively, which reduces the regional evapotranspiration (0.48%) and soil water content (0.72%). The increase in settlement area (42.23%) is the main reason for the increase in water yield (14.52%). Most land use covered by vegetation has strong water conservation capacity, and the water conservation capacity of the forest is particularly outstanding. Farmland and settlements tend to have a negative effect on water conservation. The water conservation capacity of forest at all scales decreased significantly with the growth of forest (p < 0.05), while the water conservation capacity of different tree species had no significant difference. For the study area, increasing the forest area will be an effective way to improve the water conservation function, planting evergreen conifers can rapidly improve the regional water conservation capacity, while planting deciduous conifers is of great benefit to long-term sustainable development.
