Temperature, rainfall and extreme weather have been indicated to affect the phenological patterns and forest productivity by shifting flowering and fruiting seasons and patterns, as well as crop production. see the following study....

Thank you very much. This is just what I am in need of. Please I am open to more contributions.

yes thee is rpossibility of such change due alteration in climatic factors or seasonal changes. in costal areas and hilly temperate ares these changes are more notable than other areas. even phenological changes in forest vegetaion is reported.

Yes Manmohan J.R. Dobriyal, I am very much aware of these facts. But I am in need of literature on the subject. So please if you know of any published research on the effect of climate change on the phinologoical and production patterns of the forest, it will do me much good to get such details. Thank you

In the Bolivian Amazon the 2017 brazil nut harvest (from natural forests) showed really low volumes. This phenomenon has been linked to changes in precipitation linked to changing hydrology cycles due to climate change and regional deforestation and degradation. The following text (in Spanish I’m sorry) gives more information on this subject.

We’ve seen similar effects in many other products, including cacao. We’ve noticed the delay and unpredictable start of the rainy season causes the cacao trees to abort flowers and young fruits, while the relatively few fruits that do manage to grow tend to be small and still immature at the end of the rainy season. Many fruits thus mature incompletely affecting cacao quality. I’m afraid this information has not been documented well yet: so far it’s only been written down tentatively in project reports. But I’m currently trying to write down more details in a more scientific description of adaptations and practices to improve climate change resilience in regional cacao production. Please feel free to write me at [email protected].

@Vincent, Thank you very much. Wish I understood Spanish. You have perfect understanding of the subjected matter. I will send you a message via your email. Thank you.

I am sure that Dakis-Yaoba OUEDRAOGO could help you: Dakis-Yaoba Ouédraogo
