Water availability is predicted to be reduced and temperature to rise in the global climate change context. Future climate conditions may thus represent a serious risk for coffee cultivation especially in less favorable environment. Agroforestry has been postulated as a promising strategy to adapting to climate changes. Shade tree may minimize radiation and temperature near the soil surface and reduce soil evaporation. Shade tree may enhance infiltration, reduce runoff and increase rainfall water use efficiency by taking up water from deep soil layers. However, shade tree may reduce the water that reaches the soil by rainfall interception. Trees may consume additional water and can establish a competitive relationship depending on tree species characteristics, soil water availability, site conditions and management.
In this experiment water dynamics and use was monitored in a mature agroforestry experiment where coffee shaded by a mixture of Tabebuia rosea and Simarouba glauca is compared to full sun coffee over 2012 and 2013. The water balance was obtained by two independent approaches: 1) measuring directly all components of water balance (trees and coffee transpiration; soil evaporation; rainfall interception); and 2) measuring changes in the soil water stock through Time Domain Reflectometers (TDR) probes.
Agroforestry (AFS) showed greater transpiration and lower soil surface evaporation compared to full sun (FS). Shade tree did not represent a serious constraint for coffee water use during most of the period of the experiment. Coffee water consumption represented 75% of the total transpiration in agroforestry while Tabebuia rosea transpired 17% and Simarouba glauca 8%. Complementarity was demonstrated by root niche differentiation between coffee and Simarouba glauca that seemed to be more suitable as coffee shade tree compared to Tabebuia rosea. We also demonstrated high competition between coffee and shade tree when an atypical very dry season occurred. Transpiration was stabilized although the high evaporative demand and coffee leaf water potential reached its lowest value in AFS which suggested high level of coffee water stress. Adaptation strategies for coping with climate change using shade trees need to be devised taking into account this quantified information into account.

Conforme prometido no primeiro livro, "Plantas do Pantanal", que trata de plantas terrestres, a presente obra enfoca somente especies aquaticas e semi-aquaticas. Do total estimado de 1.800 especies de Fanerogamas (ou Espermafitas, ou plantas superiores, ou que dao flor/semente) e um numero nao conhecido de inferiores da Flora do Pantanal (senso planicie), aqui sao apresentadas 247 especies das chamadas macrofitas aquaticas, ou macrofitos aquaticos, ou hidrofitas. Tem surgido muitos livros sobre plantas aquaticas para varias partes do mundo, e sobre wetlands ou areas umidas, mas poucos do Brasil. Este trabalho representa o estagio atual de conhecimento da Flora de macrofitas aquaticas do Pantanal, resultado de 15 anos de levantamento da primeira autora, e que agora esta sendo colocado a disposicao do publico, em face da grande demanda e incentivo para que fosse concluido. Mas nao significa que esteja perfeito. Alguns generos com mais especies talvez sejam ainda um pouco mais numerosos no Pantanal do que se conhece ate o momento, como Bacopa, Ludwigia, Utricularia e alguns generos de Ciperaceas e Melastomataceas. |
