I want to carry out a research on "forest ecosystem service provisioning in future drying climate".  As we know, tropical forests occur over a wide range of rainfall regimes that vary both in total precipitation and in seasonality. Both length and intensity of dry seasons can have important ecological consequences for tropical forests. As such, the vegetation patterns along environmental gradients have long been studied in ecology, but studies that link these patterns with ecosystem services are a new area for research. Information on the latter is of importance as it will contribute significantly to the understanding of changes in functioning along a rainfall gradient and more importantly, it can be used as an indicator of the effects of climate change on tropical forest ecosystems. Both length and intensity of dry seasons are predicted to increase into the future which can have important consequences for the ecosystem services provided by forests. The research will look at vegetation patterns along precipitation gradients to see how a range of services are affected e.g. carbon storage, biodiversity and water recycling, to develop predictions consistent with the predicted range expansion of tropical dry forests into moist forest zones. A combination of field measurement, remote sensing, and modelling will examine options for ecosystem service restoration.

With your expertise in this field, Please what methodology and analytical tool can I use to achieve the objectives of this research work?
