Abstract: Understanding the dynamics of multipurpose species in savanna ecosystems is essential for their sustainable conservation. This study aims to assess the population structure of five target species (Tamarindus indica, Vitellaria paradoxa, Detarium microcarpum, Anogeissus leiocarpa, and Crossopteryx febrifuga) in the forest management site of Tiogo. Floristic inventory was conducted on 100 plots of 1000 m2. Non-Metric Multidimensional Analysis was carried out to characterized the target species’ habitats. A total of 70 species distributed in 23 families and 55 genera were recorded. Four groups of overlapping plant communities were identified. Each group constitutes a habitat of target species with diverse ecological drivers. Weibull distribution showed an overall good population structure for Vitellaria paradoxa, Detarium microcarpum and Crossopteryx febrifuga. However, Tamarindus indica and Anogeissus leiocarpa showed bad regeneration potential with lack of recruitment in the smaller diameter size classes. It is therefore important to increase the monitoring in the forest management site. This work has provides valuable information for better management of target species, aiding in effective forest management of Tiogo, subject to anthropic pressures.

Abstract: Sorghum is an essential food security crop in the majority of the ASALs regions, such as Baringo County. This study investigated the critical relationship between rainfall levels and the initiation of sorghum planting, with the aim of identifying the threshold at which rainfall is considered sufficient for germination and optimal growth. This study used historical meteorological data from 1990 to 2022, field experiments, statistical analysis, and sorghum growth patterns to discern the trigger points for planting, which are essential for ensuring successful cultivation. This study uncovered alterations in rainfall onset and seasonal rainfall accumulation. The planting window in Baringo County varied significantly, with some dates falling above and below the average onset values of April 4th for the long rainfall season and September 24th for the short rainfall season. A short rainy season is not ideal for sorghum planting, as it typically receives less than 300 mm of rainfall, which is insufficient for sorghum production. The optimal planting time for sorghum is usually late March and early April. The study found that 36.4% of the long rainy season years had high production, 42.4% had normal production, and only 21% had low or no productivity. The years 2000 and 2018 experienced minimum and maximum rainfall amounts of 198.45 mm and 941.9 mm, respectively.

Abstract: The challenges of sustainable forest preservation led Burkina Faso to implement participatory forest management projects in the mid-80s. These projects led to the creation of Forest Management Sites including the one at Cassou. This innovative approach focusses on the active participation of the local communities. It raised high hopes for sustainable forest management. This presents paper traces the process and analyze the outcome derived from the participatory forest management. The Actor-network theory was used as to analyze the implementation process of the CAF model. In doing so, qualitative approach was used through key experts’ and stakeholders’ interviews and focus groups discussions to understand the trajectory and to evaluate the process of implementing the given model. The results show that the dynamic that prevailed at the beginning of the process has eroded over time to the point that after more than three decades of implementation, the model has not yet reached its phase of stabilization or irreversibility. Actors no longer seem to refer to the roles assigned to them, and they are not respecting their commitments. In part, factors such as population renewal and growth, decentralized development management (which were not taken into account at the outset) call for new forms of negotiations between stakeholders to regain control of the process for the sack of the Cassou managed forest.

Abstract: This study aimed to evaluate different varieties of groundnut introduced from four breeding programs in West Africa for their stability and adaptability in agro-ecological zones of Niger. The study used a randomized complete block design with three replicates at three locations. Analysis of variance revealed significant variation among varieties and the effect of environment on pod yield was highly significant (P<0.001). GGE biplot analysis was used to identify the best varieties for each environment and assess the stability of the newly introduced varieties. The GGE biplot described all the observed variations and explained 98.42% of the total variation, indicating a strong genotype by environment interaction effect. The evaluation of varietal performance indicated that Pyr-370 and Rafeet Car thrived exceptionally well in Bengou and Magaria, respectively, while El_Tarna exhibited the highest performance at Tarna. Variety SH470P was the most stable and productive among the introduced varieties in the different environments, while ICGV86124 was stable but low yielding. On the other hand, the introduced varieties ICGV86024, ICGV-IS14857 and Pyr-370 demonstrated superior productivity, yet their performance inconsistency underscored inherent instability.

Abstract: Ecosystem services are closely linked to the daily lives of local communities, particularly those living near forests. The study of the local perceptions of these services is relevant because they vary depending on the community, the study period, and the environment. So beyond the inventorying of ecosystem services, understanding the perceptions of local communities regarding these services remains a necessity. Our study aims to analyze how local communities perceive the ecosystem services provided by forests and the factors that determine these perceptions. We collected data from 232 heads of households across 23 villages bordering the forest and analyzed them using descriptive statistics and ordered Probit analysis. The results showed that provisioning services (such as plant-derived medicines, rafters and planks, livestock feed, crops, and firewood) were the most important, followed by regulating and supporting services (including soil formation, erosion control, and climate regulation) are the most important. Finally, cultural services (encompassing cultural practices, heritage, and spirituality) were perceived as important. However, communities did not perceive the value of ecotourism. Factors influencing these perceptions included gender (male), age (young individuals), occupation in farming, household size, level of education, Bariba ethnicity and income. To ensure the sustainable utilization of forest resources in the region, it is necessary to encourage young people to adopt environmentally friendly agricultural practices, to use improved stoves that require less wood and promote cultural services to diversify their sources of income.
