Remote Sensing for Irrigation Water Management—The State of the Art and Prospects for Near‐Future Operations

Irrigation and Drainage, EarlyView.
ABSTRACT A recent UN report describes many regions as facing ‘water bankruptcy,’ a condition in which available water resources can no longer meet existing demands. In practice, this means irrigation will likely bear the greatest burden of future water‐use reductions, a complicated and fraught decision to make given its critical role in food security ...

Genomic Offset Analyses: Mind Your Climate Variables

Global Change Biology Communications, Volume 1, Issue 2, June 2026.
Recent methods based on genomic offset (GO) statistics aim to quantify the risk of non‐adaptation of populations to future climates. This study assesses how well genomic offset values correspond to population variation in fitness, depending on the methods and climate data used.

How “visible” is urban agriculture in Cameroon? Mapping urban agriculture practices by satellite imagery and field surveys

Canadian Geographies / Géographies canadiennes, Volume 70, Issue 3, Autumn / automne 2026.
Abstract Urban agriculture (UA), although promoted in numerous sustainability agendas, has been ignored in public policies of many African countries. This study evaluates the effectiveness of interviews and mapping techniques for characterizing UA and facilitating informed decision making at the local level.

Stability in tapia woodlands amid non‐native expansion: Integrating traditional ecological knowledge and remote sensing to track 73 years of tree cover in Madagascar

People and Nature, Volume 8, Issue 5, Page 1403-1418, May 2026.
Abstract Afromontane ecosystems, characterised by mosaics of fire‐adapted grassy ecosystems and fire‐sensitive forests, are biodiversity hotspots facing escalating pressures from non‐native species, climate and land‐use change. Madagascar's Central Highlands is one such hotspot, hosting woodlands dominated by endemic Uapaca bojeri (tapia) which are ...

Spatial Distribution of European Grayling Reflects Longitudinal Temperature Patterns in a Swiss River

Ecology of Freshwater Fish, Volume 35, Issue 1, January 2026.
ABSTRACT Most salmonid populations are declining across their entire habitat range, partly because of large‐scale loss of crucial physical habitats. Alterations in river flow and temperature resulting from climate change are likely to further degrade habitat quality, particularly summer thermal conditions experienced by temperature‐sensitive fish ...

Congo Basin Carbon Cycle Responses to Global Change

Global Change Biology, Volume 32, Issue 1, January 2026.
Understanding the resilience of the Congo Basin carbon cycle in the face of current and future pressures requires a detailed understanding of its response to past and present drivers of change. Building on a pantropical framework of drivers and possible regional mechanisms for resilience, this review provides the first comprehensive assessment of Congo
