Este estudo avaliou o efeito da produção e utilização de carvão vegetal no enraizamento de uma economia verde no Quénia. Essencialmente, o estudo identificou as espécies de árvores-alvo que são uma fonte de carvão vegetal consumido na cidade de Nairobi; determinou a quantidade de carvão vegetal consumido na cidade de Nairobi; estimou o esgotamento da cobertura florestal; e investigou a sensibilização da população consumidora de carvão vegetal para os riscos ambientais da produção e utilização de carvão vegetal. O estudo adoptou uma conceção de inquérito de investigação que envolveu a utilização de um questionário semi-estruturado, com um alvo de 100 inquiridos (20 comerciantes de carvão vegetal em grande escala e 80 utilizadores de carvão vegetal), selecionados através de uma entrevista pessoa-a-pessoa, selecionada utilizando uma técnica de amostragem aleatória intencional/sistemática. Foram utilizadas técnicas estatísticas descritivas para analisar os dados de campo. Utilizando uma análise de regressão linear simples e um intervalo de confiança de 95%, o estudo revelou também, de forma significativa, que o esgotamento do coberto florestal é previsto pelo consumo de carvão vegetal, o que afecta o enraizamento de uma economia verde no Quénia.

  • Water from a Transdisciplinary Perspective
    Ana Isabel Pereira Cardoso / Teresinha M. Gonçalves
    Life in cities has distanced human beings from nature and made it difficult to understand the ecology of life dependent on the environment. Urban water collection and distribution processes contribute significantly to the fragmentation of knowledge and the vital recognition of the water cycle. Without the effective participation of the subject in environmental actions, it is no...

    Bret C. Harvey / Steven F. Railsback
    Ecologists now recognize that the dynamics of populations, communities, and ecosystems are strongly affected by adaptive individual behaviors. Yet until now, we have lacked effective and flexible methods for modeling such dynamics. Traditional ecological models become impractical with the inclusion of behavior, and the optimization approaches of behavioral ecology cannot be use...

    Carlos Martínez del Rio / William H. Karasov
    Unlocking the puzzle of how animals behave and how they interact with their environments is impossible without understanding the physiological processes that determine their use of food resources. But long overdue is a user-friendly introduction to the subject that systematically bridges the gap between physiology and ecology. Ecologists--for whom such knowledge can help clarif...

    Marten Scheffer
    How do we explain the remarkably abrupt changes that sometimes occur in nature and society--and can we predict why and when they happen? This book offers a comprehensive introduction to critical transitions in complex systems--the radical changes that happen at tipping points when thresholds are passed. Marten Scheffer accessibly describes the dynamical systems theory behind cr...
