Equity in unilateral value chain policies: A monitoring framework for the EUDR and beyond

Constance L. McDermott, Thomas Addoah, Tawiah Agyarko-Kwarteng, R. Asare et autres

Unilateral value chain policies have recently emerged as a key strategy of international land use governance. They're part of a broader trend towards trade-based environmental policies, from corporate due diligence to sustainability certification and trade moratoria, that has been critiqued for reinforcing …

Same but Different: Intersexual and Age‐Related Habitat Use of the Threatened West African Trionyx triunguis Clade—A Four‐Country Comparative Study

Edem A. Eniang, Stephanie N. Ajong, Gabriel Hoinsoudé Segniagbeto, Eniang Inemesit Edem et autres

ABSTRACT Biological communities are structured by a variety of biotic and abiotic relationships, whose understanding forms the basis for effective conservation. Among the myriad factors influencing community dynamics, resource partitioning stands out, potentially enriching ecosystem complexity but also carrying risks for conservation …

Landscape and management influences on smallholder agroforestry yields show shifts during a climate shock

A. Morel, Sheleme Demissie, Techane Gonfa, Zia Mehrabi et autres

Sustaining yields for smallholder perennial agriculture under a rapidly changing climate regime may require consideration of landscape features and on-farm management decisions in tandem. Optimising landscape and management may not be possible for maximising yields in any one year but maintaining heterogeneous …

Climate change alters impacts of extreme climate events on a tropical perennial tree crop

Thomas J. Creedy, R. Asare, A. Morel, Mark Hirons et autres

Anthropogenic climate change causes more frequent and intense fluctuations in the El Niño Southern Oscillation (ENSO). Understanding the effects of ENSO on agricultural systems is crucial for predicting and ameliorating impacts on lives and livelihoods, particularly in perennial tree crops, which may …

Proximity to forest mediates trade‐offs between yields and biodiversity of birds in oil palm smallholdings

Keith C. Hamer, Michael Adu Sasu, Linda Ofosuhene, R. Asare et autres

Abstract There is much debate about how best to mitigate the effects of agricultural expansion on biodiversity, especially in the tropics. Recent studies have emphasized that proximity to natural habitats can enhance farmland biodiversity, yet few studies have examined whether or not …

Resilience to climate shocks in the tropics

Mark Hirons, Emilie Beauchamp, Stephen Whitfield, Declan Conway et autres

Abstract This focus collection on resilience to climate shocks in the tropics draws together 16 papers that predominantly examine the impacts of, and responses to, the 2015/2016 El Niño-Southern Oscillation event, in a range of contexts. This introductory synthesis contextualises the collection …

Human Appropriated Net Primary Productivity of Complex Mosaic Landscapes

Christine Moore, A. Morel, R. Asare, Michael Adu Sasu et autres

Quantifying human impact on the environment is increasingly important and particularly so in complex mosaic landscapes. Such landscapes are prolific in the developing world, notably in West African, small holder cocoa farming communities. Human Appropriated Net Primary Productivity (HANPP) is a metric …

The Ecological Limits of Poverty Alleviation in an African Forest-Agriculture Landscape

A. Morel, Mark Hirons, Michael Adu Sasu, Marvin Quaye et autres

Cocoa yields in Ghana remain low. This has variously been attributed to low rates of fertiliser application, pollinator limitation and particularly dry growing conditions. In this paper we use an African forest-agriculture landscape dominated by cocoa (Theobroma cacao) to develop an ecological …

Carbon dynamics, net primary productivity and human‐appropriated net primary productivity across a forest–cocoa farm landscape in West Africa

A. Morel, Michael Adu Sasu, Stephen Adu‐Bredu, Marvin Quaye et autres

Abstract Terrestrial net primary productivity ( NPP ) is an important metric of ecosystem functioning; however, there are little empirical data on the NPP of human‐modified ecosystems, particularly smallholder, perennial crops like cocoa ( Theobroma cacao ), which are extensive across the …
