“…Future extractive industries may change the relatively stable situation for this site. Kasijy coincides with the Bekodoka 2104 concession to the north of the well-known Bemolanga 3102 and Tsimiroro 3104 concessions which are in advanced stages of exploitation [48]. In 2015, the Bekodoka concession was reported as being contracted to Madagascar Petroleum Energy [49].…”

Protected areas (PAs) are a cornerstone for conservation biodiversity. Madagascar, as a hotspot for biodiversity, has a network of 114 terrestrial protected areas covering the main forest types occurring on the island. Deforestation continues unabated despite the network covering 11% of the island. Here we present a case study approach reporting on four PAs from the humid forests, dry western forests, and southwestern dry and spiny forests and thickets. To describe deforestation in and around the case sites, we have considered a time window of 30 years for analysis, focusing on six years with reliable data: 1990, 2000, 2010, 2015 (the year of latest PA network update), and 2017. We have considered forest versus other land covers within the PAs in “buffers” at a distance of 500 m, 2.5 km, 5 km, and 10 km from the border of the PA. These buffers were set from the border towards the center of the PA (inside the PAs) and from the border outside the PAs. The smallest PAs, Kasijy (IUCN IV), and Behara Tranomaro (no IUCN category), showed the least forest loss. Tsaratanana (IUCN I) had the highest deforestation rates within the last two years of analysis, with deforestation concentrated in the core area. Ranobe PK-32 (no IUCN category), originally with the largest forest extent, has lost most of its forest cover and showed the highest annual deforestation rate (3.5%) between 2015 and 2017. All four cases prove to be very challenging to manage. Future conservation activities require tailored interventions to account for site-specific current and potential future threats, as detailed in this contribution.

“…In 2015, the Bekodoka concession was reported as being contracted to Madagascar Petroleum Energy [49]. In 2017, it was reported as being contracted to the company MPE (Madagascar Petroleum Energy) and in the "phase of Evaluation of EIA [Environmental Impact Assessment] for 2D seismic acquisition; seismic acquisition program" [48] (pp. 63).…”
