13. Agriculture and food security challenge of climate change: a dynamic analysis for policy selection
ABSTRACT This study presents an empirical examination of climate change related to vulnerability impacts on food security and remedial adaptation options as a suitable strategy by prioritizing needs over a 50-year period. An Empirical Dynamic Commutable General Equilibrium Model for Climate and the Economy (EDCGECE) is applied using future strategies for Mal

14. Using ecological niche models to predict the impact of global climate change on the geographical distribution and productivity of Euterpe oleracea Mart. (Arecaceae) in the Amazon
ABSTRACT We assess the impact of climate change on the geographic distribution and productivity of Euterpe oleracea (Arecaceae), commonly called açaí. To construct the ecological niche model of E. oleracea, we used 95 points of occurrence, five bioclimatic variables in current and future climate scenarios and Maxent software. The Akaike Information Criteri

15. Marine and coastal environmental education in the context of global climate changes - synthesis and subsidies for ReBentos (Coastal Benthic Habitats Monitoring Network)
Resumo A importância da educação ambiental marinha (EAM) vem tomando relevância à medida que aumenta a expectativa de impactos nos ecossistemas brasileiros ocasionados por mudanças nos ambientes costeiros. Entretanto, apenas 32 contribuições sobre esse assunto foram publicadas no Brasil. O grupo de trabalho em EAM da ReBentos objetiva promover a comu

16. Sensitivity of the sorghum yield to individual changes in climate parameters: modelling based approach
Based on sensitivity analyses the effect of changing in climate on sorghum has been investigated. This has been achieved by conducting crop modeling experiments carried out with weather observations and output of global climate models. As can be anticipated results demonstrated that the sorghum yield is more sensitive to rainfall, solar radiation and CO2 con

17. Nutrient enrichment effect on macroinvertebrates in a lowland stream of Argentina
ABSTRACT One of the most important effects derived from the intensive land use is the increase of nutrient concentration in the aquatic systems due to superficial drainage. Besides, the increment of precipitations in South America connected to the global climate change could intensify these anthropic impacts due to the changes in the runoff pattern and a gre

18. Contaminación del aire en la Ciudad Autónoma de Buenos Aires: el riesgo de hoy o el cambio climático futuro, una falsa opción
Based on the theoretical framework of environmental risk, this article discusses the management of air quality in the Autonomous City of Buenos Aires in relation to current and potential impacts of toxic gases and global climate change on the health of the population. Information on historical and current management of the air was linked to the results of th

19. Plant cells in the context of climate change
Global warming and its origins triggered the beginning to considerable discussion in the last century. Studies of climate models presented in multidisciplinary scientific reports suggest that anthropogenic activities, particularly the emission of gases from the greenhouse effect, are greatly responsible for the current climate changes. The increase of carbon

20. Hormonal changes in female buffaloes under shading in tropical climate of Eastern Amazon, Brazil
The hormonal responses of 20 female buffaloes raised under the sun (SS group) or in the shade (CS group) in Belém, Pará, Brazil, were assessed. The CS group (n = 10) was kept in a silvopasture system featuring Racosperma mangium, whereas the SS group (n = 10) was kept in paddocks without shade featuring Brachiaria humidicola, drinking water, and mineral sa

21. Los retos de la produccion de anonaceas en Mexico: produccion y mercadeo
By analyzing the current Annonaceae's world challenges in Mexico, we consider all parties, from the producer, the target markets and all the way up to final consumer. In a globalized agribusiness environment and increasingly competitive, businesses that cater to the needs of consumers are the only ones that will survive and grow. The Inter-Entrepreneurial Co

22. Oceanografia e Química: unindo conhecimentos em prol dos oceanos e da sociedade
The marine environment is certainly one of the most complex systems to study, not only because of the challenges posed by the nature of the waters, but especially due to the interactions of physical, chemical and biological processes that control the cycles of the elements. Together with analytical chemists, oceanographers have been making a great effort in

23. Proposta metodológica de medição da resiliencia agroecológica em sistemas sócio-ecológicos : um estudo de caso nos Andes colombianos / Methodological approach for measuring the socioecological systems qualification resilience: a case study in the colombian Andes
In the last tree centuries the capitalistic economic model introduced deep changes and with no precedents into the ecosystems with the aim to satisfy its own food demands, potable water, wood, fiber and energy. Those changes helped to improve the life of thousands of people, but at the same time weakened natures regulation capacity. The most evident conseque

24. Cenários futuros para a Amazônia: interações entre o desmatamento, as mudanças climáticas, o ecossistema natural e os sistemas agrícolas / Future scenarios for the Amazon: interactions between deforestation, climate change, natural ecosystem, and agricultural systems
A Floresta Amazônica é um dos mais importantes ecossistemas do mundo, possuindo a maior biodiversidade do planeta. Apesar de toda sua relevância, ela vem sendo submetida a pressões antrópicas nas últimas décadas. A expansão da agricultura e da pecuária tem sido considerada a principal causa do desmatamento na região. Considerando-se a importância
