“…Water deficit is often a key factor limiting plant growth, productivity and survival (Boyer 1982;Puri and Swamy 2001;Sánchez-Coronado et al 2007;Namirembe et al 2008), and often adversely affects agroforestry practices in arid and semi-arid areas. Plants can normally acclimate to water stress through physiological and morphological responses (Brouwer 1963;Puri and Swamy 2001;Coopman et al 2008).…”

“…Plants can normally acclimate to water stress through physiological and morphological responses (Brouwer 1963;Puri and Swamy 2001;Coopman et al 2008). For most plants, the immediate responses to water deficit are leaf water potential declines, leading to stomatal closure and reduced photosynthesis.…”

“…For most plants, the immediate responses to water deficit are leaf water potential declines, leading to stomatal closure and reduced photosynthesis. Furthermore, prolonged drought can limit plant growth and biomass production, and alter the allocation pattern of biomass, and even cause plant death (Ogbonnaya et al 1998;Puri and Swamy 2001;Gindaba et al 2004;Rodiyati et al 2005). Water-use efficiency (WUE) is a functional character related to plant growth and performance under drought conditions.…”

The adaptation responses to different water conditions and the drought tolerance of Sophora davidii seedlings were assessed in a greenhouse experiment. Two-month-old seedlings were subjected to the following water supplies for 95 days: 100, 80, 60, 40 and 20% of field water capacity. The seedlings at 100% FC had the greatest productivity, height, basal diameter, branch number, leaf number and leaf area. Water supply\80% FC was the threshold of droughtinitiated negative effects on seedling growth, yield and physiological processes; these parameters were severely reduced at 20% FC, however, there was no plant death during the experiment. Moreover, water stress decreased leaf relative water content, specific leaf area, leaf area ratio, and water-use efficiency (WUE), whereas it increased the biomass allocation to roots, which resulted in a higher root:stem mass ratio under drought. The S. davidii seedlings tolerated drought by maintaining high leaf relative water content and by reducing branching and leaf expansion. However, low productivity and WUE at 20% FC suggested that seedlings did not produce high biomass under severe drought. Therefore, prior to introducing S. davidii in forestation efforts, a water supply [40% FC is recommended for seedlings to maintain growth and productivity. These results provide insights into limitations and opportunities for establishment of S. davidii in arid regions.

“…The relationship between drought induced by climate change and tree mortality is equivocal. We found LoE2a strength evidence that severe drought can increase tree seedling mortality by 35-40% due to the inability to match transpiration demands (Puri and Swamy, 2001). However, equally robust evidence suggests that exposure to drought does not increase tree seedling mortality, despite impairments in their growth (Tamayo-Chim et al, 2012).…”

“…Our knowledge about the impacts of climate change on tree growth and distributions is based on LoE2a, LoE2b, and LoE3 strength evidence. LoE2a evidence from several studies indicate that reduced rainfall, water stress and increasing drought severity, which are expected under climate change, could limit the height and root growth of trees and plants in TAFS, including Amomum villosum (Feng and Li, 2007), Azadirachta indica (Puri and Swamy, 2001), Tectona grandis (Kumar et al, 2021), Guazuma ulmifolia, Albizia lebbeck, Leucaena leucocephala, Piscidia piscipula and Lysiloma latisiliquum (Tamayo-Chim et al, 2012). Although the consensus in these studies is that drought can negatively affect tree growth, some evidence revealed slight variation in responses.…”

Climate change is expected to adversely affect the crop yields and food security for many smallholder farmers in the tropics unless adaptive measures are implemented. Agroforestry ecosystem services, such as micro-climate buffering, have received growing attention from the academic and policy communities for alleviating the negative impacts of climate change on smallholders. These benefits imply that agroforestry could offer a suitable measure for adaptation to climate change. However, whether agroforestry systems themselves succumb to the adverse effects of climate change is often less studied in the agroforestry literature. Consequently, less is known about how climate change will impact agroforests. We conducted a systematic review, which included an evidence quality assessment, to examine the impacts of climate change on tropical agroforestry systems (TAFS). Based primarily on studies undertaking biophysical approaches, we found that climate change negatively impacts TAFS by reducing tree growth, intensifying tree-crop resource competition and reducing crop yields. However, the impacts on smallholder farmers are less clear due to limited evidence in the relevant literature. We found that the evidence supporting our findings is mostly “robust”, although “least robust” strength evidence was also commonly found. We conclude that to improve understanding of how climate change could affect the performance of TAFS as a social ecological system, more interdisciplinary studies are required. Furthermore, to improve the quality of evidence in the research field, studies should explore using mountain elevation gradients for climate analog analysis to perform the most robust study designs. We provide an interdisciplinary conceptual model, which considers the interactions and feedbacks between TAFS components noted from our review to predict the response of ecosystem services provisioning and farmers' wellbeing to climate change, to guide interdisciplinary studies using climate analog analysis.
