Aims: The aim of this research was to assess the knowledge, perceptions and attitudes of victims and stakeholders on environmental disasters occurring in Businga territory. Study Design: This research employed a descriptive study design whereby the characteristics of respondents were described. Place and Duration of Study: The study was carried out in Bodangabo, Businga and Karawa sectors of Businga territory in Nord-Ubangi, Democratic Republic of the Congo between January 2016 and December 2017. Methodology: A survey was conducted on 150 respondents among the victims and stakeholders in the prevention and management of environmental disasters in three sectors of Businga territory to whom the semi-structured questionnaire was administered. Results: The findings show that 54% of environmental disasters originate from bushfire and 46% from floods. The bushfire is more evident in the area of Bodangabo and Karawa, while the flood is noticed in the area of Businga precisely in the city, because the ¾ is largely crossed by streams (Likpolo, Lokame, Legbala, Mongala). Thus, 80% of disaster victims are not satisfied with the support. However, 96% of respondents denied the provincial government's contribution, 92% confirmed the total absence of the environmental disaster prevention policy, and 88% confirmed the inefficiency of disaster prevention mode in Businga territory. With regard to the period of onset of disasters, it is clear from this survey that the floods are sporadic and occurring every two or three years compared to the bushfire which is manifested every year. 68% of the difficulties are due to lack of awareness due to insufficient financial resources and 32% to the shortage of qualified personnel for the prevention and management of these disasters. Conclusion: The lack of a policy of prevention and management of environmental disasters both at the provincial and local levels is at the base of this high frequency. Therefore, it is relevant that a provincial body responsible for alerting and advocating to the stakeholders involved in the prevention and management of environmental disasters, to settle in all Businga sectors. Furthermore, it is necessary to install the early warning system as tool of disaster prevention.

“…The PCR system is a model for human behaviors during catastrophic events, established in 2013 to better understand and predict human reactions facing a brutal disaster [21,22,27,5] . It is given by the following adimensional system of ordinary equations:…”

“…The PCR networks that we study are inspired by some geographical configurations [22], which determine the values of the parameters of each node, according to their spatial position, and the coupling strengths, according to the dimensions of the communication paths. Thus, the geographical metric structure of the zone affected by the catastrophe is implicitly taken into account in the parameters of the network.…”

“…In this paper, we aim to present the continuation of a recent work [5], concerning the PCR system (Panic-Control-Reflex), which is a geographical model for human behaviors during catastrophic events, established in 2013 in order to better understand and predict behavioral reactions of individuals facing a brutal disaster, which can have a natural or an industrial origin [21,27,22]. In this previous work, a complete stability and bifurcation analysis of that dynamical system was proposed, exhibiting a degeneracy case of a saddle-node bifurcation at infinity, with two possible asymptotic behaviors for the solutions.…”

The purpose of this work is to study coupled networks of nonidentical instances of the PCR system (Panic-Control-Reflex), which is a geographical model for human behaviors during catastrophic events. We endow the subsequent graph with superposed linear and quadratic couplings, and explore the effect of the topology of the network on the dynamics of each node. Especially, we investigate the possibility of controlling the panic level in the network by a clever disposal of the connections. We establish a necessary and sufficient condition for synchronization, without any reductive assumption on the nature of the network, and study the global stability of the trivial equilibrium. We illustrate our theoretical results by numerical simulations of randomly generated networks.

“…The population switches between different behavioral states, some of which are the result of instinctive, others of reasoned, reaction. As the brain switches from one behavioral state to another, in the context of terrorist 1 https://geoazur.oca.eu/en/research-geoazur/2158-com2sica-how-to-comprehend-and-simulate-humanbehaviors-in-areas-facing-natural-disasters attacks and therefore in a situation of sudden and unforeseen threat, the entire impacted population first adopts a behavioral reaction, Reflex r(t), under the influence of surprise and the suddenness of the event, before transiting to the Panic reflex behavior p(t), or Controlled behavior c(t) (Provitolo et al 2015). Reflex r(t) and Panic p(t) behavior are managed by the reptilian brain: they are instinctive, automatic reactions, allowing one to react extremely quickly to the threat, either by being stunned and paralyzed r(t), or by fleeing as quickly as possible due to the panic fear p(t).…”

Terrorism has always existed in history and has taken different forms: anarchist attacks, political attacks, or attacks by colonial states, such as the terrible Jallianwala Bagh massacre, which took place on April 13, 1919 in Amritsar, Punjab, when a crowd of non-violent protesters were fired upon by troops of the British Indian Army. In this article we focus specifically on behavior of populations facing new forms of terrorism, such as the attacks perpetrated by sects, groups or "lone wolves" that are becoming more and more prevalent. Three types of acts can be distinguished:
