Although cashew vertical HR can share water with neighboring crops, its lateral HR needs clarification. Therefore, this study aimed to assess both vertical and lateral HR of cashew by observing changes in soil moisture content in a controlled experiment. The HR was evaluated on cashew seedlings with root filled in 3 connected compartment media positions, namely top, left bottom, and right bottom. The HR treatments included cashew with vertical HR (P<sub>1</sub>), where all compartments were wet, except the upper one kept dry. There was also vertical and lateral HR (P<sub>2</sub>), where all compartments were dry, except the right bottom, kept wet, and treatment without HR (P<sub>no-HR</sub>) with all compartments dry. Treatments were arranged in a complete randomized design with six replications. Water transfer through the capillary media was minimized by separating root to isolate HR effects. The results showed that there was significant vertical HR in P<sub>1</sub> with soil moisture content gap of 7.6% compared to P<sub>no-HR</sub>. In P<sub>2</sub>, lateral HR was observed with soil moisture content gap of 8.0%. Additionally, cashew in P<sub>1</sub> and P<sub>2</sub> maintained better leaf water potential and transpiration compared to P<sub>no-HR</sub>. These results confirmed that cashew could perform vertical and lateral HR, supporting their role as an upper story in dryland agroforestry. Moreover, soil moisture alternation with root separation methods could be feasible for evaluating HR on controlled scale.</p></div>","PeriodicalId":7610,"journal":{"name":"Agroforestry Systems","volume":"99 2","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142995548","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Agroforestry has been identified as a sustainable option to enhance livelihoods while limiting the threat posed by climate change. It is against this background that this study investigates the livelihood assets and resilience of agroforestry practitioners in the Republic of Congo and Chad. Making use of a mixed methods and comparative analysis approach, findings reveal different livelihood assets categorized into natural, physical, human, social, and financial capitals. Natural assets, particularly trees, are universally recognized across both countries, but water availability differs significantly, with 81% of practitioners in the Republic of Congo having access compared to only 43% in Chad. Physical assets show stark contrasts; while over 70% of practitioners in the Congo reported having access to necessary tools and irrigation systems, only 17% of those in Chad reported similar access. Human assets highlight a reliance on indigenous knowledge in both countries, yet Chad faces lower formal education levels, particularly among livestock-based agroforestry practitioners. Social capital is notably stronger in the Republic of Congo, where 72% of practitioners benefit from robust networks, compared to only 41% in Chad. Financial assets are generally low, but particularly precarious in Chad, where savings range from 8 to 26%, limiting investment capacity. Resilience scores linked to these assets reveal that agroforestry practitioners in the Republic of Congo generally demonstrate higher resilience across all categories. Regression analysis highlights a strong positive relationship between various agroforestry practices (especially food crop-based and cash crop-based systems) and livelihood resilience, with coefficients suggesting a greater impact in Chad. This underscores the urgent need for policies that enhance access to physical, human, and financial resources, particularly in Chad, to foster sustainable agricultural practices and improve food security. These findings emphasize the importance of a holistic approach to strengthen livelihood assets, enhance resilience, and promote the adoption of effective agroforestry practices in both countries.</p></div>","PeriodicalId":7610,"journal":{"name":"Agroforestry Systems","volume":"99 2","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142995547","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Notably, CLEANED does not explicitly model tree presence on farms. However, after downloading the tool, it was possible to model and precompute each farm’s characteristics based on input data, considering the exploitation mode outside the tool’s standard scope. This adaptation represents a significant contribution, showcasing how CLEANED can be tailored to evaluate SPS effectively. The analysis focused on methane (CH<sub>4</sub>) and nitrous oxide (N<sub>2</sub>O) emissions, water use per kg of product, changes in carbon storage, and economic performance.

Only one site had yield data and there, ZonalCent approach could approximate the mean yield reduction—yet more detailed evaluation is necessary. Negative correlations showed that simulated yield was most strongly affected by (a) shading by mature trees and (b) the loss of arable area due to grass strips. While more detailed models may be needed for a detailed process understanding, ZonalCent includes the most important interactions (light, water, nutrients, temperature) in a simple but effective way and can be readily used—because it is based on DayCent—to estimate the potential carbon sequestration of agroforestry systems at larger scales.</p></div>","PeriodicalId":7610,"journal":{"name":"Agroforestry Systems","volume":"99 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10457-024-01127-y.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142963047","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Understanding the factors influencing households’ tree-planting decisions is essential for shaping policies and initiatives aimed at increasing on-farm tree cover, improving farmers’ incomes, and achieving national climate and land restoration goals. This study explores the determinants of farmers’ tree-growing decisions in Kiambu County, Kenya. Data was collected through interviews with 120 households and analyzed using descriptive statistics, Probit, and double-hurdle models to assess the factors driving tree planting and diversification aspirations. Results reveal that 97% of farmers grow trees for their products, while 26% do so for ecosystem services. A majority (93%) are aware of climate change, with 66% and 71% willing to plant more trees for climate mitigation and adaptation, respectively. Probit analysis shows that factors such as land ownership, dependency ratio, labor availability, number of farms, and the belief in trees' importance to households significantly (<i>p</i> ≤ 0.05) encourage tree planting. Furthermore, education, availability of land for tree planting, and food security influence the decision to diversify tree species.
