Urban development and species invasion are two major global threats to biodiversity. These threats often co-occur, as developed areas are more prone to species invasion. However, few empirical studies have tested if both factors affect biodiversity in similar ways. Here we study the individual and combined effects of urban development and plant invasion on the composition of arthropod communities.

Despite the global implementation of rock-rubble groyne structures, there is limited research investigating their ecology, much less than for other artificial coastal structures. Here we compare the intertidal ecology of urban (or semi-urban) rock-rubble groynes and more rural natural rocky shores for three areas of the UK coastline. We collected richness and abundance data for 771 quadrats across three counties, finding a total of 81 species, with 48 species on the groynes and 71 species on the natural rocky shores.

Surge una preocupación por los impactos del COVID-19 en las agriculturas familiares campesinas. Sus relatos sostienen que no han recibido la ayuda humanitaria suficiente o el apoyo estatal acorde a la importancia de sus actividades. Esto agrava su situación de vulnerabilidad poniendo en riesgo su salud y vida. Sin duda, las medidas sanitarias implementadas para evitar la propagación del virus tienen consecuencias directas sobre el funcionamiento de los sistemas agroalimentarios y quienes lo sostienen: las familias campesinas e indígenas del país.

The preservation of soils which provide many important services to society is a pressing global issue. This is particularly the case in countries like Tanzania, which will experience rapid population growth over coming decades. The country is also currently experiencing rapid land-use change and increasing intensification of its agricultural systems to ensure sufficient food production. However, little is known regarding what the long term effects of this land use change will be, especially concerning soil quality.

Au moment où tous les pays d’Afrique de l’Ouest, à l’instar des pays des autres régions du monde, ont pris des mesures fortes pour contrer la propagation de la pandémie du COVID-19, l’APESS a voulu analyser les premiers effets de ces mesures sur ses membres.

Este informe muestra que dada la falta de limitaciones al uso de de materias primas de riesgo elevado
de deforestación, la ambición mundial actual de aumentar el uso de biocombustibles puede conducir a una mayor deforestación y a aumentos asociados de las emisiones de gases de efecto invernadero. El informe presenta escenarios de desarrollo bajo, medio y alto de la demanda de aceite de palma y soja para biocombustibles en el periodo hasta 2030
en las jurisdicciones más relevantes.

Cette note synthétise les présentations et les échanges qui ont eu lieu lors du séminaire dédié aux enjeux du foncier rural au Mali, organisé à l’initiative du CTFD en avril 2019.

Ces deux jours ont rassemblé une cinquantaine de participants venus du Mali et de France : des membres d’organisations de la société civile, des représentants d’organisations paysannes, des représentants de l’Office du Niger et du ministère de l’Agriculture du Mali, ainsi que des chercheurs, experts fonciers, opérateurs de projets et des membres du CTFD et des agents de l’AFD en France.

Labor migration and large-scale land enclosures are increasingly central to the story of agrarian change throughout the Global South. Nonetheless, there remain limited understandings of how recent explosions of mobile labor and new sources of smallholder capital shape and are shaped by ongoing land use and property transformations. This article reviews this gap in Southeast Asia – a region where labor and capital are highly mobile and where the expansion of industrial agriculture and forestry has been particularly rapid.

This paper deepens the economic analysis of the effects of land consolidation – reduction of land fragmentation. It does this in the context of rural Vietnam, studying whether land consolidation promotes or hinders the Vietnamese government's policy objectives of encouraging agricultural mechanization and stimulating the off-farm rural economy. The analysis views land consolidation as a form of technical change, making it possible to apply the rich insights developed in the economic literature on that subject.

Restoration of marginal and degraded lands is essential for regaining biodiversity and ecosystems services, and thereby attaining UN-Sustainable Development Goals. During the last few decades, many fast growing and hardy trees have been introduced worldwide to restore the marginal and degraded lands for ecosystem stability. Unfortunately, most of these introduced species have become invasive and invaded the nearby productive systems, leading to significant biodiversity loss and land degradation.

With the aim of improving farmland use efficiency without damaging the social function of farmland, Chinese policymakers have proposed the ‘trifurcation of land rights’ reform. When it comes to realization of the law, however, neither the Ownership Model nor the Bundle of Sticks Model can adequately explain this reform. The tree concept of property, which provides a new perspective in delineating property rights based on the function served by specific properties, is thus adopted.

Growing domestic and international ethanol demand is expected to result in increased sugarcane cultivation in Brazil. Sugarcane expansion currently results in land-use changes mainly in the Cerrado and Atlantic Forest biomes, two severely threatened biodiversity hotspots. This study quantifies potential biodiversity impacts of increased ethanol demand in Brazil in a spatially explicit manner. We project changes in potential total, threatened, endemic, and range-restricted mammals’ species richness up to 2030.
