In the context of climate change, the need to contribute to achieving Sustainable Development Goal (SDG) 2 is no longer in doubt, especially in sub-Saharan Africa. In this study of the landscape within 10 km of the Donomadé model farm, southeastern Togo, researchers sought to assess vegetation health in ecosystems and agrosystems, including their capacity to produce biomass for agroecological practices. Sentinel-2 sensor data from 2015, 2017, 2020, and 2022 were preprocessed and used to calculate the normalized vegetation fire ratio index (NBR), the vegetation fire severity index (dNBR), and CASA-SEBAL models. From these different analyses, it was found that vegetation stress increased across the landscape depending on the year of the time series. The research estimated that 9952.215 ha, 10,397.43 ha, and 9854.90 ha were highly stressed in 2015, 2017, and 2020, respectively. Analysis of the level of interannual severity revealed the existence of highly photosynthetic areas that had experienced stress. These areas, which were likely to have been subjected to agricultural practices, were estimated to be 8704.871 ha (dNBR2017–2015), 8253.17 ha (dNBR2020–2017), and 7513.93 ha (dNBR2022–2020). In 2022, the total available biomass estimated by remote sensing was 3,741,715 ± 119.26 kgC/ha/y. The annual average was 3401.55 ± 119.26 kgC/ha/y. In contrast, the total area of healthy vegetation was estimated to be 4594.43 ha, 4301.30 ha, and 4320.85 ha, in 2015, 2017, and 2022, respectively. The acceptance threshold of the net primary productivity (NPP) of the study area was 96%. The coefficient of skewness (0.81 ± 0.073) indicated a mosaic landscape. Productive and functional ecosystem components were present, but these were highly dispersed. These findings suggest a great opportunity to promote agroecological practices. Mulching may be an excellent technique for enhancing overall ecosystem services as targeted by the SDGs, by means of reconversion of plant biomass consumed by vegetation fires or slash-and-burn agricultural practices.

In Togo, the Oti-Kéran-Mandouri (OKM) complex had important biological-oriented tourism activities in 1980s. However, degradation of ecosystems has negatively affected the biological resources of these protected areas. This study aims at analysing the current biological-based ecotourism potential of the OKM complex facing conservation challenges. To this end, a mixed approach combining fauna and flora inventories with ethnobotanical surveys was adopted.. Results showed that the floristic potential is characterized by 287 species distributed into 63 botanical families and 170 genera. A total of 26 and 19 woody species were identified as species with 'high cultural value' and 'high attractive potential', respectively. In terms of animal diversity, 11 species of the large wildlife, including emblematic species, have been recorded. Six of these animal and plant species are reported in the IUCN Red List. These findings provide insights on the great potential of OKM complex for ecotourism promotion in Togo. [ABSTRACT FROM AUTHOR]
