To ensure new plantations are adaptive to future climates, it is crucial to consider climate mismatches resulting from climate change when selecting tree species. However, current research is all species-based, which is not effective for species selection across species at specific plantation sites. Our research developed a novel site-based approach that can identify optimal tree species for specific planting sites under projected future climates. We evaluated the feasibility and effectiveness of this method across 10 representative sites in diverse climatic zones in China based on climate niche projections for 100 key tree species. Our findings demonstrated the necessity and effectiveness of this approach, which can select a suit of suitable tree species tailored for any potential planting site across China under different climate change scenarios. For instance, at Tibet Dongjiu Forest farm, <em>Aibes densa</em> and <em>Quercus pannosa</em> currently showed high suitability scores above 0.8 (on a scale of 0–1). However, by the 2080s, <em>Aibes densa</em>'s suitability was projected to drop to 0.25, while <em>Quercus pannosa</em> was expected to maintain its suitability. Conversely, <em>Quercus aquifolioides</em> currently had a low suitability of 0.08, but it was projected to increase to 0.74 by the 2080s. These findings demonstrate the importance of using this approach to avoid selecting the wrong species or overlooking potentially suitable species. In addition, our simulation analysis suggests that a dataset of 40–50 species is necessary to ensure that most planting sites can identify 2–3 suitable species. This advancement significantly enhances the precision and effectiveness of tree species selection strategies for local practitioners, offering vital insights for forestry, conservation, and ecological restoration projects. These results highlight the tremendous potential and practical applicability of our site-based approach in enhancing forestry adaptation and ecological functions in response to global climate change.</div></div>","PeriodicalId":100262,"journal":{"name":"Climate Smart Agriculture","volume":"1 2","pages":"Article 100019"},"PeriodicalIF":0.0,"publicationDate":"2024-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142358735","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Film mulching and ridging are key agricultural methods in potato cultivation. Investigating the impact of these methods on N<sub>2</sub>O emissions, nitrifying/denitrifying functional genes, and microbial communities can provide a theoretical basis for soil emission reduction and more sustainable dryland agriculture. We examine the effects of flat tillage with mulching, ridge tillage with mulching, flat tillage without mulching, and ridge tillage without mulching, on potato fields under natural rainfall conditions in Wuchuan County, China. N<sub>2</sub>O emission fluxes were monitored using a static (dark) chamber and gas chromatography. Real-time quantitative PCR (q-PCR) was used to quantify abundances of nitrifying and denitrifying bacteria related to N<sub>2</sub>O emissions at various potato-growth stages. Illumina high-throughput sequencing was used to investigate microbial community structure by targeting 16S rRNA genes; related soil elements (soil temperatures and moisture) are analyzed. Mulching and ridging indirectly influence N<sub>2</sub>O emissions, nitrifying/denitrifying functional gene copy numbers, and microbial community structure by altering soil temperature and moisture. Cumulative N<sub>2</sub>O emissions and emission intensity were both consistently higher in ridge tillage with mulching during the potato-growing period. Ammonia-oxidizing archaea are the main microorganisms that control N<sub>2</sub>O emissions, with nitrification-coupled denitrification also being an important mechanism contributing to high N<sub>2</sub>O emissions during soil dry–wet cycles. Increased soil temperature and moisture elevated N<sub>2</sub>O emissions and functional gene copy numbers.

Specifically, we focused on the role of entrepreneurship orientation (risk taking, proactiveness and innovativeness) and uptake of climate smart agricultural (CSA) practices in improving adaptive capacity – a dimension which has received limited research attention. Adaptive capacity was measured using a set of indicators representing the five capitals in the Sustainable Livelihood Framework (SLF). The determinants of adaptive capacity were analyzed using fractional and censored regression models. The results revealed mixed influence of entrepreneurship orientation on adaptive capacity. While risk taking and proactiveness were positively associated with a higher adaptive capacity, innovativeness did not have any influence. Similarly, uptake of livestock CSA practices was associated with a higher level of adaptive capacity. Other factors that positively influenced adaptive capacity were age, gender, education level, diversity of income, access to extension services, credit, and collective action. The findings suggest that a strategy to promote entrepreneurial orientation, uptake of CSA, accumulation of human and financial capital would enhance livestock producers’ adaptive capacity.</p></div>","PeriodicalId":100262,"journal":{"name":"Climate Smart Agriculture","volume":"1 1","pages":"Article 100007"},"PeriodicalIF":0.0,"publicationDate":"2024-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2950409024000078/pdfft?md5=2f5748e5f1a8cac7d282495dbcbb4e11&pid=1-s2.0-S2950409024000078-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141699944","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this gap, we investigated drainage water quality, water quantity, nutrient uptake, soil carbon, and rice yield in rice paddies in histosol soils over a two-year period at four flood depths (5, 10, 15, and 20 ​cm).

In doing so, they should also consider community monitoring and indigenous knowledge, which can help bridge the gap between local adverse impacts and the necessary adaptations to climate change.</p></div>","PeriodicalId":100262,"journal":{"name":"Climate Smart Agriculture","volume":"1 1","pages":"Article 100004"},"PeriodicalIF":0.0,"publicationDate":"2024-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2950409024000042/pdfft?md5=30e1d6a9348ce693c369713b8bf718f9&pid=1-s2.0-S2950409024000042-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141023372","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is also a vulnerable sector under climate change. The term climate-smart agriculture has been widely used since its inception in 2010, but no clear and unified understanding of its scientific meaning exists. Here, we systematically analyzed the relationship between agriculture and climate change and interpreted the scientific definition of climate-smart agriculture. We believe that climate-smart agriculture represents a modern production approach to coordinatively promote food security, climate mitigation benefits and agricultural adaptation to climate change towards the Sustainable Development Goals. In addition, due to the worsening global climate change situation, we expounded on the urgency and major challenges in promoting climate-smart agriculture.</p></div>","PeriodicalId":100262,"journal":{"name":"Climate Smart Agriculture","volume":"1 1","pages":"Article 100003"},"PeriodicalIF":0.0,"publicationDate":"2024-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2950409024000030/pdfft?md5=5c5abd295882d7dd6990e43dd33886ce&pid=1-s2.0-S2950409024000030-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141027560","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
