A Novel Approach to Integrating Community Knowledge into Fuzzy Logic-Adapted Spatial Modeling in the Analysis of Natural Resource Conflicts
Abstract
:1. Introduction
- SEFLAME-CM constructs the Conflict Vulnerability Likelihood Index One and Two (CVL Index 1 and 2), adapted from [10]. The CVL Index is a measurement indicator [47] that guides NRC management towards sustainability by integrating multifaceted dimensions of drivers that had not been considered holistically by NRC management researchers.
- In a community-level case study of NRCs, SEFLAME-CM exemplifies a pragmatic application of fuzzy logic that surpasses innovative feasibility methods such as the Pythagorean fuzzy rough set or the intuitionistic approach [42,43]. SEFLAME-CM adeptly manages multiple and frequently conflicting criteria, incorporating the perceptions of conflict drivers and weighing by local stakeholders. This enhances sustainability beyond numerous applications of analogous models in other contexts [34,37,38,39,49,50,51].
- Although prior research on NRCs provides a viable framework for examining the interconnections of drivers, it does not yield an optimal resolution, as a comprehensive understanding of conflicts at their occurrence level is essential. The model presented by [45,52] considered intricate interactions with socio-economic factors yet adhered to a black-box methodology. In contrast, our model demonstrates greater flexibility by addressing micro-level uncertainty through integration.
- SEFLAME-CM transcends the fuzzification of explanatory variables, as evidenced in the study by [53]. In SEFLAME-CM, both the output and explanatory variables were fuzzified. We used fuzzy explanatory and response variables in a spatial context to develop CVL Index 2. This improved the fuzzy common vulnerability scoring system (F-CVSS), which is predicated on a least squares methodology and the fuzzy logistic regression model proposed in [53]. In our case, we examined the spatio-temporal dimensions, main driver parameters encompassing environmental, socio-economic, and political factors, as well as resource–conflict typologies. Our discussion shows great insights into NRC research at a fine-grained scale. Recent studies, possibly constrained by the constraints of machine learning techniques, have not investigated the complex links among the drivers of conflicts [45].
- Our community approach exceeds that of [36], which encountered substantial constraints on data collection owing to protected cultural locations. This differs from our approach, where we coupled stakeholders’ opinions with remotely sensed and fuzzy logic data to guide sustainability.
2. Materials and Methods
- The first step is joint problem analysis and structuring. The aim is to identify and structure the problem of NRCs within the context of a transdisciplinary coupled approach [10]. This step includes exploratory visits and measurement of biophysical components of the parameters using remote sensing. It also includes problem analysis using interviews, etc.
- The second step is modeling and simulation. As a precursor, FLAME-CM was first developed, followed by SEFLAME-CM, as stated in step 3. Refer to Section 2 for the procedures that led to the steps for the models.
- The third step was spatialization of information with geoinformation (GI) tools: here we used GIs tools to prepare the various spatial layers using state-of-the art geoinformation tools and software. Steps 2 and 3 were based on the multilevel algorithm described in Section 2.2.
- The fourth step is the integrative analysis step: we visualized the results from step three and prepared the data for model comparison with previous methods.
- In the fifth step, we compared our model with previously used models. This was based on the following: First, we conducted a time scale validation. Here we looked at the vulnerability dimensions as different conditions that could influence the occurrence of NRCs. Second, we compared the two types of NRCs studied with the three dimensions. Third, we compared the result of the model SEFLAME-CM with existing models. The results of the fifth step informed the analysis results presented in the Section 4.
- Finally, we proposed the evaluation of possible scenarios, a necessary step that future researchers could take up.

4.1. Implications of Spatio-Temporal Distribution of NRCs: Ogoni (Inland) and Okrika (Coastland)
- Rebel NRCs (Inland): For the rebel type of NRCs in Ogoni, the spatial CVL Index is projected to be 0% for both the 1986–2000 and 2000–2016 periods. The index experienced a decline from a probability of 12%, classified as very likely, during the period from 1986 to 2000, to 55%, classified as very likely, in the subsequent period from 2000 to 2016. As expected, the index experienced a decline from 55% during the period of 1986–2000, decreasing to 33% in the subsequent period from 2000 to 2016.
- Territorial NRCs (Inland): The dynamics of NRCs in Ogoni are most significant in instances of territorial disputes. The spatial CVL Index is estimated to have risen from most likely (0%) during the period of 1986–2000 to 33% in 2000–2016. Moreover, the index rose from very likely (39%) to 47% during the periods of 1986–2000 and 2000–2016, respectively. In contrast to rebel NRCs in Ogoni, the issues concerning land resources and territorial claims hold greater significance than uprisings and youthful aggression [91].
- All NRCs (Inland): In Ogoni, the index recorded a most likely value of 3% during the period from 1986 to 2000, and a value of 0% from 2000 to 2016. Recent years have shown a noticeable reduction in conflicts within the inland regions, especially in the Ogoni territory. A notable trend of conflict diffusion from inland areas to coastal regions has been observed over time. Initial investigations into NRCs have primarily focused on the initiation and length of conflicts and resource-related conflicts throughout history [5]. The study was unable to elucidate the factors contributing to the reduction and dispersion of conflicts across various regions without conducting an analysis or measurement of conflicts at the sub-national level [15,100].
- Rebel NRCs on the Coast: The index was most likely (49%) in Okrika for the period of 1986 to 2000. Within the period from 2000 to 2016, the percentage increased to 65%. Between the two-year periods of our investigation, the spatial index was very likely and reduced from 17% to 1%. In addition, the index fell under the likely category but dropped from 30% to 0% across the two periods.
- Territorial NRCs on the Coast: The index of the 1986 to 2000 period was most likely (33%) in Okrika. This saw a slight increase to 34% within 2000 to 2016. A comparative analysis of the Ogoni area (inland) reveals that the coastland exhibits a higher susceptibility to resource conflicts concerning telluric resources [101]. This suggests a significant likelihood of heightened territorial disputes in the future, particularly in coastal regions.
- All NRCs on the Coast: In Okrika, the index score fell within the most likely category. This almost doubled from (16%) from 1986 to 2000 to 30% in the 2000–2016 era. The most likely category’s spatial CVL index rose from 48% between 1986 and 2000 to 60% between 2000 and 2016. The findings suggest a spread of conflicts from the inland (Ogoni) to the coastal zone.
