“…The multivariate regression model was used to determine the factors affecting rural household income (Hartono et al, 2011;Hartono and Rohaeni, 2014;Akouegnonhou and Demirbaş / Selcuk J Agr Food Sci, (2021) 35 (3): 210-217 Marwati et al, 2020). Rural household income is composed of farm income and off-farm income (Richard et al, 2016;Marwati et al, 2020) Y = b 0 + b 1 X 1 +b 2 X 2 +b 3 X 3 +b 4 X 4 +b 5 X 5 +b 6 X 6 +b 7 X 7 +b 8 X 8 +b 9 X 9 +b 10 X 10 + e Y= Household income X 1 : Age X 2 : Education level X 3 : Experience in livestock farming X 4 : Access to credit X 5 : Number of cattle X 6 : Number of sheep X 7 : Pasture use X 8 : Access to veterinary services X 9 : Membership to a livestock organization X 10 : Number of family members b 0 : Intercept b = 1, 2,…10: Regression coefficients associated with X 1 , X 2 , … X 10 , respectively.…”

The development of many African countries' economy and life of the rural population in the south of the Sahara depends on the agricultural sector. Seventy to 80% of the active population was employed in the agricultural sector. The contribution of the agricultural sector to the Gross Domestic Product (GDP) of these countries ranged from 30% to 50%. The rural population in these countries has lived under low life standards and in economically unfavourable conditions (Diallo, 2004). In Benin Republic, economic activities were predominantly based on agriculture, and the agricultural sector contributes about 32.5% to GDP, 75% to exports, 15% to tax revenues and about 70% to employment (FAO, 2018). Agriculture is then seen as a sector with many potentials that should be seriously exploited to support national economic growth and thus contribute to the effective fight against poverty.

“…For instance, rule R47 assumes that wild (Bw) and domestic (Go) browsers should co-occur to enable epidemics to emerge. However, in areas where browsers are now extinct, livestock are still subject to diseases [97]. Therefore, we could split this rule as R47a: Bw+, Rf+, Sw+ » Bw-, Go-, and R47b: Go+, Rf+, Sw+ » Bw-, Go-.…”

Sub-Saharan social-ecological systems are undergoing changes in environmental conditions, including modifications in rainfall pattern and biodiversity loss. Consequences of such changes depend on complex causal chains which call for integrated management strategies whose efficiency could benefit from ecosystem dynamic modeling. However, ecosystem models often require lots of quantitative information for estimating parameters, which is often unavailable. Alternatively, qualitative modeling frameworks have proved useful for explaining ecosystem responses to perturbations, while only requiring qualitative information about social-ecological interactions and events and providing more general predictions due to their validity for wide ranges of parameter values. In this paper, we propose the Ecological Discrete-Event Network (EDEN), an innovative qualitative dynamic modeling framework based on “if-then” rules generating non-deterministic dynamics. Based on expert knowledge, observations, and literature, we use EDEN to assess the effect of permanent changes in surface water and herbivores diversity on vegetation and socio-economic transitions in an East African savanna. Results show that water availability drives changes in vegetation and socio-economic transitions, while herbivore functional groups have highly contrasted effects depending on the group. This first use of EDEN in a savanna context is promising for bridging expert knowledge and ecosystem modeling.

“…Les caprins au Tchad représentent 32,5% de l'ensemble du bétail national avec un effectif de 30 519 349 de têtes (MEPA, 2018). Malgré leur forte contribution à l'économie et à la sécurité alimentaire des ménages des pays du sahel, la majorité des caprins reste cependant conduite selon des modes d'élevage extensifs avec l'utilisation de ressources naturelles, de résidus de culture et peu d'intrants alimentaires (Houessou et al, 2021 ;Idrissou et al, 2018 ;Richard et al, 2019).…”

L’objet de cette étude a été d’identifier les pratiques d’alimentation des caprins Kirdimi dans le Département de la Tandjilé-Centre. L’étude s’est déroulée de décembre 2021 à janvier 2022 dans 21 villages. Les données ont été collectées auprès de 315 ménages agro-éleveurs choisis de manière aléatoire. Il ressort que les ressources alimentaires consommées par les caprins sont : les fourrages naturels, les résidus de récolte et les compléments alimentaires (sous-produits artisanaux, agro-industriels et les déchets de cuisine). Quinze (15) herbacées et vingt-cinq (25) ligneuses fourragères les plus consommées par les caprins ont été identifiés. Trois (3) types de complémentations ont été identifiées : le type 1 qui renferme 89,71% des éleveurs dont les animaux reçoivent les sous-produits artisanaux, le type 2 où 9,65% des éleveurs qui utilisent les sous-produits artisanaux et les sous-produits agro-industriels et le type 3 minoritaire où seulement 0,64% des éleveurs complémente avec les sous-produits agro-industriels. Les ressources alimentaires des caprins dans la Tandjilé-Centre sont constituées surtout des fourrages des parcours naturels et des sous-produits (de récoltes, agroindustriels et artisanaux). Une analyse bromatologique permettrait d’apprécier leurs valeurs alimentaires afin de mieux les valoriser dans l’alimentation des caprins et améliorer leurs performances zootechniques. The purpose of this study was to identify the feeding practices of Kirdimi goats in the Department of Centre Tandjilé. The study took place from December 2021 to January 2022 in 21 villages. Data were collected from 315 randomly selected agro-pastoralist households. It appears that the food resources consumed by goats are: natural fodder, crop residues, and food supplements (artisanal by-products, agro-industrial, and kitchen waste). Fifteen (15) herbaceous and twenty-five (25) woody forages most consumed by goats have been identified. Three (3) types of supplementation have been identified: type 1 which contains 89.71% of livestock farmers who receive artisanal by-products, type 2, or 9.65% of farmers who use artisanal by-products and agro-industrial by-products and minority type 3 where only 0.64% of farmers supplement with agro-industrial by-products. The food resources of goats in the Centre Tandjilé Department consist mainly of fodder from natural rangelands and by-products (harvests, agro-industrial and artisanal). A bromatological analysis would make it possible to assess their food values to better value them in the diet of goats and improve their zoo technical performance.
