Côte d'Ivoire and Ghana, the world's largest producers of cocoa, account for two thirds global cocoa production. In both countries, is primary perennial crop, providing income to almost million farmers. Yet precise maps area planted with are missing, hindering accurate quantification expansion in protected areas, production yields limiting information available improved sustainability governance.

Abstract Few ecosystems are more sensitive to hydrological change than seasonally-flooded wetlands. Here, we investigate how changes in regimes caused by the construction of two dams have contributed large structure and dynamics Kafue Flats, an internationally-important, partially-protected wetland ecosystem Zambia. We use historical (1970) contemporary (2013) data describe hydrology due dam operations, compare areal extent, distribution, composition major dryland habitats pre- post-dam...
Retaining trees in low-input agroecosystems could be key to maintain mycelia of arbuscular mycorrhizal fungi (AMF) and hence, improve soil fertility crop performance. We assessed the impact faidherbia (Faidherbia albida, Fabaceae) mango (Mangifera indica, Anacardiaceae) on AMF smallholder farmers' maize fields. Along distance-from-tree gradients (1, 4, 10, 15 m), we collected assess hyphal density, aggregation, aggregate-associated carbon (C), nitrogen (N), phosphorus (P) at end non-cropping...
Abstract Extreme weather events have severe impacts on food systems, especially for smallholders in global value chains (GFVCs). There is an urgent need to understand (a) how climate shocks manifest and (b) what strategies can enhance system resilience. Integrating satellite, household trade data, we investigate the cascading after two consecutive hurricanes smallholder banana farmers Dominican Republic, determinants of their recovery. We found that experienced ‘all-or-nothing’ pattern...

Balancing forest conservation and agricultural production is essential for a sustainable future. Here we review the scientific evidence relationships between forests productivity across different scales, summarizing contexts under which trees limit, maintain, or enhance productivity. While synergies trade-offs occur at local regional-scale meta-analysis reveals mostly positive effects of average national-level projected to decline once cover loss exceeds ~48%, with 95% confidence interval...
Reconciling agricultural production with climate-change mitigation and adaptation is one of the most formidable problems in sustainability. One proposed strategy for addressing this problem judicious retention trees systems. However, magnitude current future-potential benefit that contribute remains uncertain, particularly sector where can also limit production. Here we help to resolve these issues across a West African region responsible producing $\approx$60% world's cocoa, crop...

CONTEXT: Agricultural extension, including cocoa expansion, has been linked to deforestation and biodiversity loss in West Africa, notably Côte d'Ivoire, the world's leading producer. Agroforestry systems could potentially increase sustainability of production. However, despite long history cultivation agroforestry systems, exact mechanism or combination factors that drive growth yield these agroecosystems, especially at establishment stage, is unclear.OBJECTIVE: The present study aims...
Abstract Trees within farmers' fields can enhance systems' longer-term productivity e.g., via nutrient amelioration, which is indispensable to attain sustainable agroecosystems. While arbuscular mycorrhizal fungi (AMF) are known improve plant access soil nutrients, the potential of AMF facilitate transfer from trees crops unclear. We used 15 N (nitrogen) natural abundance technique together with root and exclusion plots assess if Faidherbia albida (faidherbia) deliver maize associated in...
