The role of indigenous knowledge in increasing context specificity and exposing blind spots in scientific understanding is widely evidenced in disaster studies. This paper aims to structure the processes that shape indigenous knowledge production and its optimisation using the case of floods. An inductive analytical approach is applied among riparian indigenous communities ( focus on the Bayira) of the Rwenzori region of Uganda where plenty of indigenous flood practices have been recorded. Indigenous knowledge of floods is found to be based on intimate comprehension of local hydrometeorological regularities. Insofar as these regularities follow natural dynamics, indigenous socio-epistemic processes are noted to be consistent with the laws of nature. Coupled with regular open sociocultural deliberations, the conceptualisation of hydrometeorological regu-larities induces an indigenous ontology and empiricist epistemology. This, together with the techniques used, is the driver of crucial epistemic virtues which enable indigenous knowledge to provide disaster solutions that are adapted, pragmatic, and holistic.

Above-ground biomass cover under Coffea arabica on sloping land is beneficial but difficult to sustain. Interplanting annual and perennial legumes can sustain the above-ground biomass cover, and improve soil fertility, yield, and profitability. This was tested on 26 sloping farms in a four-growing season experiment on undersowing C. arabica with new crop combinations: Mucuna pruriens var. utilis (T1); Millettia dura Dunn (T2); a combination of M. pruriens and M. dura (T3); and the control with a no-cover legume (T4). On each farm, all treatments followed a randomized single-block design. T3 produced 8.7 mt/ha/yr above-ground biomass that was significantly (p < 0.01) higher than other treatments and was increasing with the seasons. Under T3, plant-available nitrogen (N) and potassium (K) increased more than in other treatments. During the fourth season, coffee yield in T3 was 54%, 22%, and 11% higher than in T4, T2, and T1, respectively. The gross profit under T3 was 86% higher than in T4 in the fourth season. This indicates that interplanting a combination of M. pruriens and M. dura under C. arabica on sloping land can sustainably increase above-ground biomass cover, soil’s plant-available N and K, coffee yield, and profitability. Based on the results, the combination of M. pruriens and M. dura is recommended to optimize coffee production under the described conditions.
Integrating indigenous knowledge with science to suitably tackle disasters due to climate and environmental change: an overview of the progress and way forward
(Science Direct-Elsevier, 2023-03-24) Bwambale, Bosco
Scholars and related institutions widely emphasize integrating indigenous knowledge with science to produce hybrid knowledge to suitably tackle disasters from climate and environmental hazards. Based on the case of hydrometeorological disasters, in which debates on incorporating indigenous knowledge are most cited, this chapter presents a review of key case studies on the progress made. It focuses on the (socio-)epistemic nature of indigenous knowledge and the frameworks being advanced on the best ways to integrate it with science. It is noted that indigenous people systematically learn from experience and concrete outcomes of their pragmatic practices to produce epistemic practices that enable them to reliably understand and tackle disasters. A trend is noted in the frameworks advanced to integrate indigenous knowledge with science: from content (where Indigenous people played a commentator role on strategies developed by scientists) to processes (where they are considered equal partners in knowledge production and development of strategies). Drawing on insights from this trend, the chapter concludes with a concise overview of the way forward: toward the development of a practical philosophy that elaborates elements from the Indigenous knowledge system for hybrid epistemologies from which actions can be developed for disaster risk reduction.
Politicizing disaster governance: can a board game stimulate discussions around disasters as matters of concern?
(Sage Journals, 2022-01-17) Mertens, Kewan; Bwambale, Bosco; Delima, Gina
The disaster risk reduction (DRR) community tends to treat disasters and risks in a managerial and technocratic way, thereby disregarding the highly political nature of DRR. An alternative epistemology of disasters, as “matters of concern”, is proposed and tested. Mobilizing concepts from Chantal Mouffe and Bruno Latour, this paper illustrates how DRR can be transformed into a public issue. It is argued that education and policymaking on DRR would benefit from a recognition of the hybrid nature of disasters. A serious game is used to investigate proposed epistemology. The board game simulates political decision-making on the reduction of risks due to floods and landslides in South-West Uganda. It is hypothesized that the game can generate an ideal speech scenario that fosters discussions among players and possibly even creates a space of political confrontation. Discussions during ten gameplays have been recorded, transcribed and analyzed (1) to understand how the dominant epistemology facilitates an apolitical approach to disasters and (2) to understand the process of politicization and de-politicization brought about when playing the board game in order to derive recommendations for future tools to facilitate a political appreciation of disasters. Our results indicate that participants effectively experience affects, power relations and confrontations during the game, but that a call for consensus and technical solutions is used by the players to close the discussions and move on with concrete solutions. Insights from this paper contribute to understanding why DRR is frequently treated as a technical issue in local and international disaster governance. Epistemology and approaches proposed in this paper are expected to stimulate innovative experiments towards a more political approach to DRR education and policy.
Re-assembling land degradation: toward a nature-society-inclusive soil erosion management strategy: a case of the Rwenzori region, Uganda
(Frontiers, 2023-05-02) Kahigwa Tibasiima, Thaddeo; Bwambale, Bosco; Ekyaligonza, Deous Mary; Dietrich, Phillipp; Jumba, Francis; Freyer, Bernard; Kanahe Kagorora, John Patrick
Tackling land degradation, particularly soil erosion, remains a challenge due to the gap between science, policy, and practice which hampers the adoption of control measures by farmers. Bridging this gap requires understanding land degradation as an assemblage of the natural/biophysical and anthropogenic aspects; but also, rethinking epistemologies that level the grounds between scientists, policymakers, and farmers whose farm livelihoods are at-risk due to soil erosion. This study aimed to clarify how these requirements can be met through the lens of the recently proposed hylomorphic framework. This framework structures, in three steps, the procedure of bridging real-life experiences of farmers at risk of soil erosion with the knowledge of scientists and policymakers through the embracement of diversity in ontological realities and values, self-critiques, and coalescing overlaps in theorizations. We selected a qualitative design as most appropriate using one of the cases—the Rwenzori region—where soil erosion is high. We conducted nine focus group discussions with participants selected purposefully from three stakeholder groups including scientists, policymakers, and farmers. Following the hylomorphic framework procedure, we carried out the content analysis. Drawing on insights from this study, we elaborate on how the hylomorphic framework supports deconstructing land degradation and soil erosion, and also further offers insights into a more nature-society-inclusive soil erosion management strategy.
What controls physical vulnerability to geo-hydrological hazards?: a contribution to quantitative assessment of landslide and flood risk in western Uganda
(European Geosciences Union, 2023-05) Sekajugo, John; Kagoro-Rugunda, Grace; Mutyebere, Rodgers; Kabaseke, Clovis; Mubiru, David; Namara, Esther; Kanyiginya, Violet; Bwambale, Bosco; Jacobs Jacobs, Liesbet; Dewitte, Olivier; Kervyn, Matthieu
Geo-hydrological hazards (landslides and floods) are often associated with significant damages on physical infrastructure like buildings and roads. Understanding the factors controlling the extent of damage is a prerequisite for quantitatively estimating risk and its spatial distribution, and advising on measures to reduce vulnerability. In this study we document the impact of 64 landslide and six flood events in four selected districts in western Uganda for the period May 2019 - March 2021 through extensive fieldwork. We quantify in economic value the physical damage of landslide and flood hazards on exposed buildings, roads and bridges. We then analyse the physical vulnerability based on damage ratios and determine the factors (building material, hazard characteristics and age of the building) that control the degree of damage using fractional logistic regression. Out of the 91 buildings affected by landslides, 54% were totally destroyed, and only 10% not or minorly damaged, for an average damage cost of 3,179 USD/building. For the 212 documented buildings affected by floods, 35% were totally destroyed, 28% had severe to moderate damage and the rest were minorly or not affected, with an average damage costs of 1,755 USD/building. The physical vulnerability of buildings to landslides depends on the size of the landslide, age of the building, type of building wall material and the steepness of the slope cut to establish an artificial foundation platform. On the other hand, the physical vulnerability of buildings to flood hazards is largely controlled by the flood depth, the distance from the river channel, slope, size of flooded area and type of floor material. The physical vulnerability functions developed in this study are being used as a new inputs into a regional quantitative model of geo-hydrological risks. Combining the hazard estimates with the most accurate information on exposure of physical infrastructure, will facilitate the identification of the types of events and the locations that require most attention for risk reduction.
