We are working on a project to assess land use intensification and its impacts on a tropical rainforest over a 40 year period.We are particular interested in knowing if the forests have changed,what has changed and what is pushing this change?We are as well interested in knowing the livelihood adaptive capacities of the indigenous communities as per these changes if any.
Thank you.
I recommend several chapters of the book Ecology and Conservation of Neotropical Forests. Manuel R. Guariguata and Gustavo Kattan (eds) 2002.

Prof Pontius and several co-authors developed Intensity Analysis for land use change which I think can be used for your purpose. I suggest you check him in google scholar (Robert Gilmore Pontius) He is also in Researchgate. I co-authored an article with him earlier this year which is in our profile in researchgate.
Best of luck
Thank you very much Enaruvbe and Herrera,i'll check them out.
Regards.
You can also use FAO forest cover trends, alternatively, the average decline in the proportion of forested land and subsequent recovery can be assessed through satellite data. I suggest a paper Mayes et al (2015) for forest cover change published in Remote Sensing of Environment.
Try to use methodic LANDEP I.( https://www.researchgate.net/publication/278300846_Landscape_Ecological_Plannig_LANDEP_I._(system_approach_in_the_landscape_ecology) ) . It is comprehensive methodic of Landscape Ecological Planing, these methodic is international and it is used in AGEND 21. I think you need some ortophoto images which you will vectorized in GIS in two or more years (e.g. 2015 and 1975). Then you will assess changes - spatial, processes - natural and antrophogenetic. You will have your own statistics data. You can estimate landscape-ecological limits and propose regulativs for environmetal optimization for landuse and sustainability of specific region.

Hello Lišková,
Accept my deep appreciation. The book is indeed a masterpiece.
Best regards,
Beckline.
Dear Beckline,
your welcome, I hope you will find information and methods you need to complete your research. Also please upload your research when it will be done, it seems to be very interesting.
Best regards

Hi Mukete, I wish you lots of success with this project. My interests have now moved too far away from nature conservation to be of any help.
Hello Mukete,
It is important to keep in mind that the procedures and methods used to detect change and monitor an area of interest can be different for highly vegetated areas (such as your site I believe) than for those used in not so highly vegetated sites (e.g., arid to semi-arid landscapes). At times change detection may be more successful if the analyses includes looking at not only differences in the spectral characteristics but also the spatial characteristics at local, intermediate, and regional scales (with the same spatial resolution images; for example, using Landsat TM --- or World View or whatever --- look at the spatial information of a 5x5, 31x31, and 101x101 pixel windows --- so not different resolution data sets).
One last thing: for change detection radiometric calibration (including atmospheric corrections) can be very important (can be absolute or relative). Below are links to two papers within research gate related to =: 1) spatial variability differences in the NIR and Visible bands and 2) atmospheric correction and how a simple DOS can be as good as, or better, than most other methods for highly vegetation areas.
Shows that the spatial variability in highly vegetated areas is higher in the NIR band than the Visible bands --- this is important when the area of interest is highly vegetated and the application is for both spatial and change detection analyses:

Image based atmospheric COST correction model and shows that for highly vegetated areas that a simple DOS type correction does as good as, and at times better, than most other techniques for visible bands --- important for change detection using visible bands for highly vegetation areas of interest:

Goodday Prof van Straalen,thank you and no student ever forgets a good teacher!
Hello Chavez, am most grateful for your inputs.AM already looking at your links which i know are just perfect.For sure,my study area is a moist tropical rainforest, highly vegetative.
