Over the past few decades, increasingly intensive maize farming by smallholders in the uplands of northern Thailand has produced a maize boom that has fed the country’s livestock industry. Despite continuously high demand for feed maize, its cultivation has declined unexpectedly over the past decade, pointing to a major land use transition in the uplands. This study investigates the causes of this maize bust and its accompanying land use changes from the perspectives of smallholders. Drawing from fieldwork in the northern province of Nan, we examined their household-level decision-making, challenges, and future visions around land use and livelihoods.

Soil-dwelling insect pests may cause considerable damage to crops worldwide, and their belowground lifestyle makes them hard to control. Amongst the most promising control agents for subterranean pests are soilborne entomopathogenic fungi (EPF) such as Metarhizium brunneum. Albeit EPF can be highly pathogenic to their target pest species under laboratory conditions, their efcacy in the feld is often limited due to adverse environmental conditions. Here, we test for the first time if the efcacy of EPF can be improved when they are augmented with trap crops.

One of the core challenges to achieve land degradation neutrality (LDN) is to spatially identify, and strategically prioritise, the areas to implement actions to avoid, reduce and reverse land degradation. To achieve this, a tool for a participatory and data-driven assessment considering both the biophysical and socio-economic dimensions of land degradation across scales was developed for Ecuador. In this paper, we present the methodology and results obtained, including the spatially explicit interactive tool developed to integrate indicators that support the scaling-up of sustainable land management (SLM).
