Framework for participatory and collaborative modelling (using generic framework from Basco-Carrera et al. (2017)) applied to the Kibera case study

FactorParameterSubparameterKibera flood model
Context and applicationProblem typeProblem descriptionA project initiated in 2015 to involve residents in flood risk management processes in the low-income and informal Kibera neighbourhood of Nairobi
Problem structureThe problem can be described as ‘unstructured’ – meaning a low degree of consensus between stakeholders and a lack of scientific certainty following the description of Basco-Carrera et al. (2017) 
Scale of actionThe geographic flood model extents were defined as the Kibera neighbourhood in downtown Nairobi and surrounding neighbourhoods (2100 ha). The total upstream catchment draining to the Nairobi dam is 4500 ha, and upstream of Kibera consists mainly of protected forested areas (the Ngong Forest)
Time horizonThe outputs of the modelling process were applied in the development of flood risk awareness exercises as well as built projects in the settlement in 2015–2018
Domain Prior to this project, no flood mapping had been produced for the Kibera settlement to the knowledge of the authors. A series of models are emerging in 2018–2019 for Nairobi and for Kibera in particular
Interaction contextCo-operative/competitiveModel specification included open-source software and multistakeholder participation in model development and application. The interaction context was highly co-operative
Specific useParticipatory/collaborative modelling purpose(a) Decision-making, (b) collaborative learning, (c) mediation, (d) model improvementRelevant project objectives from the Kounkuey Design Initiative (KDI, 2015): (a) the need to develop an approach to flood modelling and risk mapping that is applicable in the informal context and integrates community-level information on multiple hazards and risks and (b) the need to build the capacity of institutional stakeholders to undertake integrated FRM and implement flood management options in a consultative and collaborative fashion
 Planning/management cycle phasePolicy (treatment of riparian zones), planning (small- and large-scale), implementation (site-specific flood risk assessments)
Information handlingModel characterisationModel system focus/model typeOne-dimensional (1D) hydraulic computer-based model
Modelling tool/software platformMapping and analysis of catchment data with Quantum GIS model build carried out using 1D Flood Modeller, (free to use for models with fewer than 250 computational nodes)
Information typeThe 1D Flood Modeller software simulates several input storm scenarios and produces outputs at all cross-sectional locations. The model calculates the flood flow, stage (level of water) and velocity at the centre of the channel for each cross section and interpolates between the sections, approximately every 100 m. The stage information was used in conjunction with the lidar topographic surface to estimate flood depths and create flood depth and flood extent maps
Information delivery mediumVirtual/web/face to faceDuring the process, information was accessed directly from the model, through online and printed maps, and used in workshop formats
Stakeholder involvement structureParticipatory methodParticipatory/collaborativeTechnical, institutional civil society and resident stakeholders were officially involved in all stages of the modelling process, although the level of participation varied depending on the stage
Stakeholders involvedOrganisation(s)KDI: non-profit, urban intermediary – project leaderBuroHappold (BH) Engineering – modelling teamNairobi City County (NCC) – Department of Public Works – governmentKibera community-based organisations (CBOs) – civil societyStockholm University/Technical University of Kenya (TUK) – academic institutions
 Type of stakeAdvocate for resident’s engagement in planning and the integration of scientific and local knowledgeInternational engineering firm gaining experience in a new geography, exposing team members to new experiences, corporate social responsibility valueMandate to manage municipal drainage and reduce flood impacts. Important voter issueCBO groups of Kibera residents living along the river involved in data collection, model verification, model application (project development). Often identify flood risk as number one environmental challengeAdvisory role and potential user
 Skills and knowledgeEngineering, design, planning and community professionals. Limited modelling experience/capacityExtensive expertise in flood modellingSome technical capacityLocal knowledge of flood impacts (Mulligan et al., 2017)Significant modelling experience at TUK
Model usersDirect/indirectBH – main direct users; KDI and NCC indirect users
 Technical skillsKDI and TUK have the technical skills to take on and adapt the model with training from BH
Participation modeOnly modellers (no participation)/individuals/groupsModel definition was defined by BH and KDI. Modelling was carried out by BH with inputs from KDI. Some consultation with other partners (i.e. TUK)
Level of participationIgnorance/awareness/information/consultation/discussion/co-design/co-decision-makingThe stakeholder group was involved at different levels, at different stages, from ignorance to co-decision-making. This is explored further in Section 5
Timing of participationData collection/model definition/model construction/model validation and verification/model use/formulation of measures and design of strategiesTechnical, governmental, civil society and resident stakeholders were officially involved in all stages of the modelling process although the level of participation at each stage of each partner varied significantly. This is explored further in Section 6 of this paper
Type of co-operationUnilateral action/coordination/collaboration/joint actionThe type of co-operation depended on the type of application but tended towards collaboration and joint action. This is explored further in Section 6
