Climate Effect

Effective management of slow-onset impacts such as coastal erosion, desertification and sea level rise and their often-transformative impacts on communities and countries has remained relatively unexplored in terms of policy and finance responses. Drawing on relevant global experience, this paper investigates recent approaches to planned relocation as one possible response to climate change impacts and considers principles to inform the design of a fair and effective funding system.
Slow-onset events (SOE) such as sea level rise, desertification, salinisation, ocean acidification, loss of biodiversity and forests or glacial retreat fall under loss and damage (L&D) from climate change impacts under the United Nations Framework Convention on Climate Change and are increasingly threatening the environment and people's livelihoods. Irreversible SOE are closely linked to non-economic losses (NEL) such as health, human mobility or loss of ecosystem services. Neither L&D from SOE nor NELs have a dedicated funding stream.

This review article examines observed and projected climate change impacts on water security across the world's drylands to the year 2100.
Agriculture consumes huge amounts of water in China and is profoundly affected by climate change. This study projects the agricultural water use towards 2030 under the climate change mitigation target at the provincial level in China by linking a computable general equilibrium (CGE) model and a regression model. By solving the endogeneities amongst agricultural water use, output and climate factors, we explore how these variables affect water use and further predict future trends through soft-link with the IMED|CGE model.
Tillage is the most common agricultural practice dating back to the origin of agriculture. In recent decades, no-tillage (NT) has been introduced to improve soil and water quality. However, changes in soil properties resulting from long-term NT can increase losses of dissolved phosphorus, nitrate and some classes of pesticides, and NT effect on nitrous oxide (N2O) emission remains controversial. Complementary management that enhances the overall environmental benefits of NT is therefore crucial.
Climate, land use and land cover (LULC) changes are among the primary driving forces of soil loss. Decoupling their effects can help in understanding the magnitude and trend of soil loss in response to human activities and ecosystem management. Here, the RUSLE model was applied to estimate the spatial-temporal variations of soil loss rate in the Three Gorges Reservoir (TGR) area during 2001–2015, followed by a scenario design to decouple the effects of climate and LULC changes. The results showed that increasing rainfall generated as much as 2.90 × 107 t soil loss in the TGR area.
Approximately 1 billion people currently live in informal settlements, primarily in urban areas in low- and middle-income countries. Informal settlements are defined by poor-quality houses or shacks built outside formal laws and regulations. Most informal settlements lack piped water or adequate provision for sanitation, drainage, and public services. Many are on dangerous sites because their inhabitants have a higher chance of avoiding eviction. This paper considers how to build resilience to the impacts of climate change in informal settlements.

Actions on climate change (SDG 13), including in the food system, are crucial. SDG 13 needs to align with the Paris Agreement, given that UNFCCC negotiations set the framework for climate change actions. Food system actions can have synergies and trade-offs, as illustrated by the case for nitrogen fertiliser. SDG 13 actions that reduce emissions can have positive impacts on other SDGs (e.g. 3, 6, 12, 14, 15); but such actions should not undermine the adaptation goals of SDG 13 and SDGs 1, 2, 5 and 10.
Referred to as the ‘forgotten causalities’ of climate change (Cutter 1995), very few studies have examined the precise nature and magnitude of climate change impacts on children, let alone on the growing number of orphans and vulnerable children in Sub-Sahara Africa (SSA), where climate change is already expected to exact its worst humanitarian toll. This paper examines personal, familial, and contextual circumstances that arise when children lose their parents to HIV/AIDS and how these situations mediate exposure to the impacts of climate-related disasters.
Growing media (substrate) is a fundamental part of a green roof, providing water, nutrients and support to plants. However, little research has reviewed how it affects plant performances in different climatic regions. This study aims to analyse published research on green roof growing medium across world's climate zones. Findings are structured according to Köppen–Geiger climate classification, aiming to investigate the prevalence of research conducted in different climate zones. Results from full-scale studies and laboratory or greenhouse experiments were reviewed.
