Logging in the Congo Basin is geared towards selecting a minority of species with a high
commercial value. The long-term conservation of these species has become a major challenge for ecologists
and forest managers. The silvicultural approach is one of the best ways of promoting the long-term conser-
vation of these species. This study focused on Pericopsis elata, a heliophilous species found in the semi-de-
high-quality timber, it is listed in CITES appendix II (CoP18 #17) and is recorded as Endangered A2cd on the

Our presentation will show how controlling planting density and selecting outbred seeds can improve the
growth and adaptation of P. elata seedlings to changing environmental conditions.

Secondary data from the CARE project documents and reporting from the M&E section of the organization
has provided the necessary empirical data needed for the study. Also, the necessary theoretical literature and
important body of research from the South Asian context have been used to conduct the study on women’s
empowerment. This brings us to explore the question on, how women can advocate themselves against gen-

as the women for women is the only solution for the women’s empowerment.
Through economic empowerment, the organization has helped women secure their entitlements to health,
education, and other basic rights. The women’s empowerment impact statement consists of three domains of
and strong social movements built on women’s solidarity and participation of men. The three levers of women’s
choose is the empowerment and in this case the organization is providing certain support for the marginalized
population for availing their choice. To exercise the choice depends on three interrelated terms: resources
(pre-condition), agency (process), and achievements (outcomes). This paper provides insight into Bangladesh’s

Over-extraction of groundwater in the agricultural sector exacerbated water stress in rural In-
dia (Taylor, 2013). Climate change is compounding the stress by increasing the frequency, severity and extent
of droughts, thereby threatening crop production and rural livelihoods (IPCC, 2014). Adapting to scarce water
and droughts is vital for sustainable transition in rural societies. Despite women being primarily responsible for
of sustainable adaptation to water scarcity in rural parts of eastern India. The aim is to explore gendered and
situated understanding of sustainable adaptation. A grounded theory and qualitative approach was adopted to
health, time, and income. Therefore, water crisis is as part of a bigger crisis of reproduction of holistic ‘Nature’,
covering ecological commons, livelihoods, and gendered labour. Expanding upon the social reproduction theo-

ratives, over reproduction and non-economic values. Climate change aggravates these ‘boundary struggles’
(Fraser, 2017), rendering especially Dalit, Adivasi and poorest rural women intersectionally vulnerable to the
vanishing water and ecological commons. Consequently, women are severely overburdened with reproductive
labour, while water and other commons continue to be instrumentalized for increasing agricultural produc-
tion. In order to sustainably transform these boundary struggles, the paper argues for integrating adaptation

parts (e.g., feces, bones, blood) from wildlife. This review thus aims to analyze the impact of zootherapeutic
practices on African biodiversity. We conducted a systematic literature search to characterize temporal and
spatial trends of the impact of zootherapeutic practices on African biodiversity. We included 53 studies repor-
ting the use of 540 animal species in over 2,000 zootherapeutic practices. Half of these studies were published
in the last three years, indicating a recent surge of interest. Nigerian, Ethiopian and South African practices
recorded practices involved both wild (genus Smutsia, Loxodonta, Crocuta) and domestic species (genus Bos,
Gallus, Capra). Further, while some practices required animal parts that imply harm to the animal (internal
organs, blood, bones), other practices were harmless (e.g -
therapeutic practices disproportionally harmed endangered wildlife compared to domestic animal: the odds of

Nowadays, there are various anthropogenic activities that have the potential to pollute
groundwater resources. Therefore monitoring the quality of groundwater resources quality and identifying
vulnerable areas to pollution are important. However, there are few studies and minimal worries about re-
vulnerability of groundwater in the Jimma area using the DRASTIC model. The seven DRASTIC parameters.
The DRASTIC model uses seven layers of hydrogeological data: the depth to the water table, the recharge, the
aquifer media, the soil media, the topography, the impact of the vadose zone, and the hydraulic conductivity of
of the model. The DRASTIC vulnerability index was calculated in ArcGIS as a weighted sum. The DRASTIC
vulnerability index in the region varies from 84 to 187, depending on the location. 3, 70, 26, and 1 percent of
the area, respectively, are at low, medium, high very high vulnerability. The DRASTIC index indicated a mode-

The study investigates land cover change and its drivers in Mt. Guna. The recent land cover
map was generated from 2018 Google Earth imagery, while historical land cover maps were generated from
aerial photos of 1957 and 1980.
Multi-scale Geographically Weighted Regression (GWR) and Ordinary Least Squares (OLS) methods
were used to analyze land cover changes between three periods and the factors driving these changes. The
analysis revealed that dynamic land cover change observed in Mt. Guna between 1957 and 2018, is primarily

density, slope gradient and clustered homestead density are major drivers of land cover change.

sustainable balance in human-environment interactions. Therefore, it is crucial to adopt protected area mana-

By employing the ecosystem services approach, it is possible to achieve conservation objectives while also
recognizing and incorporating the social, economic, and cultural values associated with nature.

Understanding the aquifer recharge-discharge system of a catchment is a fundament for the

the Gilgel Gibe catchment where groundwater demand for irrigation, domestic and industrial purposes is dra-

sustainability. Ground-based hydrometeorological 36 years’ data from 17 stations and satellite products from
BFS through the main catchment and sub-catchments, the groundwater recharge was estimated. The input data
groundwater was estimated to be 313 mm by SMB for the years 1985 to 2020 and 314 mm by BFS for the years
1986 to 2003. The result from the SMB method revealed geographical heterogeneity in annual groundwater
groundwater recharge using the BFS method, which varies from 181 to 411 mm for sub-catchments. Hydrogeo-

for springs’ geology are basalt, ignimbrite, trachyte, and alluvial deposits. Springs with the highest discharge
are in basaltic lithology followed by ignimbrite and trachyte. Various faults and joints, which are either parallel,
perpendicular, or oblique compered to regional structures, were observed. Typical geomorphology set-ups for
springs is also controlled by land use, slope gradient and drainage density. Interviews conducted revealed, there
are springs which are not adequate during the dry season as the spring discharge decreases and there are water
quality problems from old schemes. People’s perceptions about the change of volume of spring water, change
in rainfall and temperature indicate the local community has climate change awareness. Increasing number
of population and decreasing precipitation pattern will cause failure to comply with water demand in future
generations.
