This study provides evidence on the effectiveness of community controls in regulating the use of common agricultural land in Côte d'Ivoire and tests for factors such as group size, ethnic and income heterogeneity of the group, income and resource stock levels, in explaining the variation in effectiveness across communities. The results indicate significant deterioration in community controls. These results point towards the need for a comprehensive policy framework towards agriculture in general and land tenure in particular. The study also finds that smaller and ethnically homogenous communities are better able to coordinate their actions, thereby internalizing a higher proportion of the value of land as a factor of agricultural production than their large ethnically heterogenous counterparts. No evidence is, however, found in favour of income heterogeneity hindering or facilitating collective action.

This paper describes artisanal gold mining practices and environmental impacts around the Ity-Floleu gold mine, in western Côte d'Ivoire. Interviews and field observations as well as measurements of turbidity and water flow velocity in the section of the river (Cavally) watering the study area, made it possible to identify 13 artisanal mining sites, housing 247 artisans, operating in groups made up mainly of 5 to 10 people. The activity is dominated by local populations from the villages of Ity and Floleu and the surrounding communities. Gold mined comes from alluvial and vein ores, with a predominance of alluvial ore, extracted in the sediments of the bed and the banks of the river and in the soils, inside forests. In the bed of the river, sediments are dredged using machines placed on boats, from where they are washed in mats and then dumped into the watercourse. On the other hand, on the banks of the river and in the forests, the material used consists of picks, dabas, mats, and shovels. In all cases, gold is recovered as a concentrate of gold powder. As regards vein ores, they are also extracted along with the soils of cultivable land, but in the form of blocks of stone which are crushed and washed. The gold is then recovered using mercury, followed by cyanidation. The techniques used lead to the silting up and the fall of the banks of the river, reduction of agricultural land, and the degradation of the environment by the tailings. The Cavally River appears to be strongly impacted in the midstream part of the Ity-Floleu axis, marked by a decrease in the bed and the river flow velocity (0.19 m/s) and higher turbidity (255.3 NTU). More effective policies are urgently needed to restore degraded ecosystems, both aquatic and terrestrial.

En Côte d’Ivoire, les pressions exercées sur les terres agricoles ont réduit la durée des jachères naturelles dominées par une végétation herbacée et dont la présence constitue une opportunité pour l’amélioration de la fertilité azotée des sols et la reconstitution minérale des sols dégradés. Pour cette étude, un inventaire floristique des légumineuses herbacées spontanées les plus répandues dans les jachères en constitution ont été effectuées suivie de la caractérisation physicochimique des échantillons du sol sous ces légumineuses ou non (témoin). Au total 6 espèces appartenant à deux familles (Fabaceae et Mimosaceae) et quatre genres (Calopogonium, Centrosema, Crotalaria et Pueraria) ont été inventoriées. Toutes ces espèces sont des Phanérophytes constitués majoritairement de lianes (83%) contre une minorité d’herbacées (17%). Le rapport C/N a varié de 09,5 à 12,8, demeurant ainsi dans la norme (9-12). Les sols prélevés sont quasi riches en matière organique (>1,30 g kg-1) à l’exception de celui recueilli sous Mimosa invisa (1,18±1,1g kg-1). La matière organique intervient dans les mécanismes de la libération de l’azote minéral, donc de la nutrition de la culture associée. Elle influe selon sa nature sur les propriétés physico-chimiques et biologiques du sol et a la capacité d’emmagasiner les réserves en eau.Mots clés : jachères naturelles, légumineuses subligneuses, inventaire, fertilisation, Côte d’Ivoire English title: Effects of six most common spontaneous legumes in natural fallows on soil fertility in the region of Daloa (Côte d’Ivoire)In Côte d'Ivoire, pressures on agricultural land have reduced the duration of natural fallows dominated by herbaceous vegetation and whose presence constitutes an opportunity for improving the nitrogen fertility of soils and the mineral replenishment of degraded soils. For this study, a floristic inventory of the most recurrent spontaneous herbaceous legumes colonizing these fallows in constitution was carried out followed by the physicochemical characterization of the soil samples under these legumes or not (control). A total of six species belonging to two families (Fabaceae and Mimosaceae) and four genera (Calopogonium, Centrosema, Crotalaria and Pueraria) were inventoried. All these species are Phanerophytes made up mainly of lianas (83%) against a minority of herbs (17%). The C / N ratio varied from 09.5 to 12.8, thus remaining within the norm (9-12). The soils sampled are almost rich in organic matter (> 1.30 g kg-1) with the exception of that collected under Mimosa invisa (1.18 ± 1.1 g kg-1). Organic matter is involved in the mechanisms of the release of mineral nitrogen, and therefore of the nutrition of the associated crop. Depending on its nature, it influences the physicochemical and biological properties of the soil and has the capacity to store water reserves.Keywords: Natural fallows, sublimers legumes, inventory, fertilization, Côte d’Ivoire.

Agroforestry is part of the package of good agricultural practices (GAPs) referred to as a reference to basic environmental and operational conditions necessary for the safe, healthy, and sustainable production of cocoa. Furthermore, cocoa agroforestry is one of the most effective nature-based solutions to address global change including land degradation, nutrient depletion, climate change, biodiversity loss, food and nutrition insecurity, and rural poverty and current cocoa supply chain issues. This study was carried out in South-Western Côte d’Ivoire through a household survey to assess the willingness of cocoa farmers to adopt cocoa agroforestry, a key step towards achieving sustainability in the cocoa supply chain markedly threatened by all types of biophysical and socio-economic challenges. In total, 910 cocoa households were randomly selected and individually interviewed using a structured questionnaire. Findings revealed that from the overwhelming proportion of farmers practicing full-sun cocoa farming with little or no companion trees associated, 50.2 to 82.1% were willing to plant and to keep fewer than 20 trees per ha in their farms for more than 20 years after planting. The most preferred trees provide a range of ecosystem services, including timber and food production, as well as shade regulation. More than half of the interviewed households considered keeping in their trees in their plantations for more than 20 years subject to the existence of a formal contract to protect their rights and tree ownership. This opinion is significantly affected by age, gender, access to seedlings of companion trees and financial resources. A bold step forward towards transitioning to cocoa agroforestry and thereby agroecological intensification lies in (i) solving the issue of land tenure and tree ownership by raising awareness about the new forest code and, particularly, the understanding of cocoa agroforestry, (ii) highlighting the added value of trees in cocoa lands, and (iii) facilitating access to improved cocoa companion tree materials and incentives. Trends emerged from this six-year-old study about potential obstacles likely to impede the adoption of agroforestry by cocoa farmers meet the conclusions of several studies recently rolled out in the same region for a sustainable cocoa sector, thereby confirming that not only the relevance of this work but also its contribution to paving the way for the promotion of agroecological transition in cocoa farming.

Using Côte d’Ivoire and Rwanda as case studies, this paper explores the challenges of implementing strong land tenure policies and promoting peace in post-conflict environments. This paper analyzes the degree to which a lack of clear time horizons, land boundaries, land transfer laws, and enforcement capacity to uphold land tenure laws increases the risk for land-related conflict to occur. Furthermore, this paper adds to the existing literature that supports the implementation and promotion of new and more equitable land tenure laws in post-conflict reconstruction processes in order to fix the deficiencies that contributed to the initial conflict.

This study explores in a sociological and anthropological perspectives, the efficiency of the policy of registration of customary rights in Côte d’Ivoire, by borrowing from Chauveau (2014: 49), his position on the paradigm of the formalization of customary rights. The study is essentially qualitative and took place in 5 implementation zones of the pilot phase of the 98-land law in Côte d’Ivoire.   Its results that the challenges and causes of  the failure of the land tenure policy of the state of Côte d’Ivoire during the pilot phase of generalization and formalization of the 1198 law. Finally, it lifts a corner of the veil on the stakes of pursuing this policy through a legal tidying up, because of the sustainability of debt assistance from development partners. The results of the study analyse successively: (i) the rural land policy, (ii) the pilot and generalization phase of the implementation of the 1998 law, (iii) the determinants of failures, and (iv) the asymmetrical perspectives.
