“…As variáveis topográficas também exercem influência sobre o comportamento dos incêndios florestais devido à sua capacidade de alterar o microclima e, por vezes, a composição vegetal [79]. De acordo com [57], a propagação dos incêndios é mais rápida em aclives e mais lenta em declives. Isso ocorre porque a condição do terreno faz com que as chamas entrem em contato com o material combustível que se encontra à frente da linha de fogo, elevando a velocidade de propagação [65].…”

“…Temperaturas elevadas e ventos muito frequentes aumentam a evapotranspiração e a velocidade de secagem da vegetação, tornando os ambientes mais suscetíveis à ocorrência de incêndios florestais [82] [83]. A precipitação e a umidade relativa do ar, assim como a temperatura, têm influência sobre a umidade do material combustível, apresentando, então, uma relação inversamente proporcional à probabilidade de ocorrência de incêndios [7] [57].…”

Os incêndios florestais apresentam efeitos adversos ao planeta, como fragmentação florestal, perda de biodiversidade, poluição do ar e ameaça à vida e à saúde humana. No entanto, a ecologia do fogo atesta que o fogo é também um evento ecológico, dinâmico e indispensável para a sobrevivência de determinados ecossistemas. Devido a essa ambiguidade, esta revisão teve como objetivo sintetizar informações técnicas, literárias e científicas que auxiliem no entendimento das relações entre os ecossistemas e os incêndios florestais. Assim, foram abordados assuntos diretamente ligados à ecologia do fogo, como a dinâmica dos regimes de fogo, o comportamento do fogo, a relação entre os incêndios florestais e as emissões de carbono no Brasil. Mediante as informações compiladas, percebe-se que o fogo é indispensável para a sobrevivência de muitas fitofisionomias brasileiras existentes, principalmente no Cerrado, Pantanal e Pampa. Uma série de adaptações de espécies vegetais presentes em ambientes influenciados pelo fogo foram apresentadas. Também foi investigado o papel das variáveis no comportamento do fogo e como os incêndios estão relacionados às alterações climáticas. Estima-se que queimas não associadas ao desmatamento totalizaram 3,16 GtCO2 de emissões imediatas entre 1990 e 2020, sendo um dos principais contribuintes para emissão de gases de efeito estufa. Diante desse contexto, esta revisão ressalta a importância do desenvolvimento de políticas públicas para efeitos de curto e longo prazo de maneira a popularizar a conservação e o uso sustentável do fogo em ecossistemas propensos a ação dele.

“…Timely notification of local authorities upon fire detection is of utmost importance, enabling a swift and coordinated response. Fires identified in their early stages are inherently more manageable, and the expeditious relay of information plays a crucial role in this regard [29,30]. A proactive approach to communication not only aids in extinguishing emerging fires but also minimizes the potential for prolonged blazes resulting from delayed awareness.…”

The sustainable management of forest ecosystems is directly linked to the management of forest fires. The increasing occurrence of wildfires has prompted the need for the establishment of infrastructure aimed at addressing them. The placement of anti-fire water reservoirs can address the lack of water intake points. This study introduces a decision support system (DSS) tailored for the optimal allocation of anti-fire water reservoirs in Mediterranean forest ecosystems, ensuring a reliable water supply for firefighting operations. The methodology integrates the analytical hierarchy process (AHP) and the technique of order of preference by similarity to ideal solutions (TOPSIS) methods, facilitating precise location determination through comprehensive criteria analysis. Additionally, the analysis of the forest road network is incorporated to optimize the placement of water reservoirs. In the forest complex of Taxiarchis, Chalkidiki, Greece, 100 potential reservoir sites were identified and prioritized based on factors such as fire risk, proximity to existing water sources, and coverage area using optimal pathways. The study’s findings demonstrate that by establishing 34 water reservoirs, firefighting forces can access a replenishment point within a 5-min travel time. The conclusions underscore the efficacy of this methodology as a valuable decision-making tool for sustainable wildfire prevention planning. This approach contributes to allocating resources judiciously, effectively mitigating the wildfire risk in Mediterranean forest ecosystems, and therefore promoting sustainability.

“…With climate change in mind reservoirs are helping communities in different ways such as water shortage problem. In addition to that Ramalho et al investigated how location of reservoir can help in fighting against forest fire [3]. The authors concluded that global warming will increase incident of forest fire therefore reservoirs can be placed in areas with high-and very high-risk of fires to reduce the risk.…”

Reservoirs are important for flood control, production of hydroelectric power, fishing, water harvesting and storage. Climate is changing, population and anthropogenic activities are increasing which increase sedimentation rate to most of reservoirs reducing their capacity. With climate change in mind water are becoming scarce resources which need proper storage when available and suitable flood control in areas with unpredicted rainfall. Furthermore, population growth and increases energy demand suggesting that there is a need of sustainable management of dams so as to control flood, produce more hydroelectric power and store water for use in dry season. Sedimentation is one of the factors influencing storage capacity of the reservoir. Understanding sedimentation rate, source of sediment and carryout proper management measures is one among of the important methods to preserve dams. 137 Cs and 210 Pb are important radionuclides for investigating sedimentation rate in reservoir. The method has been used for more than two decades in developed countries with less use in developing countries. In this study a sediment core was sampled at the centre of Nyumba ya Mungu reservoir in Tanzania then the samples were transported to China for processing and analysis. High-purity Germanium detector was used to analyze 210 Pb and 137 Cs. The results showed that rate of sedimentation in the reservoir ranged from 0.21 to 0.65 cm/year with more sediment coming from Kikuletwa than Ruvu tributary. Proper utilization of this method can bring sustainable management of water, save communities from flood disaster and high production of hydroelectric power.
