Species–area relationship has been widely addressed on many plant communities, but very few have conducted on epiphytic communities. Epiphytic plants are plentiful on ancient tea trees (Camelia sinensis var. assamica) in the well-known Jingmai tea plantation area, Langcang region of Yunnan Province, SW China, and add to the plant community biodiversity. We investigated 343 tea trees with various ground diameter, canopy area, under branch height, and tree height. A total of 146 vascular epiphytic plants, belonging to 19 species in seven families were recorded from the trunk or branches of 93 (27.11%) investigated trees. We examined in situ abundance, richness, and diversity (Shannon–Weiner index) of the recorded vascular epiphytes, and their relationships to tree variables. Our results showed that the distribution (abundance, richness, and diversity) of epiphytic plants are significantly related to the canopy area (p<0.05) and basal diameter (p<0.0001) of tea trees, supporting their use as key factors and good predictor for the epiphyte’s appearance in this type of agro-ecosystems. We also concluded that the species–area relationship is a useful epiphytic species community research tool.

Transparent monitoring in practice: A guide to effective monitoring in the land sector. Book II – Case studies of transparent monitoring approaches
Land management plays a crucial role in addressing climate change, which makes transparent monitoring essential. Countries have considerable flexibility in setting targets, defining the scope of the land sector, and reporting of greenhouse gas emissions and removals from it. They are, however, required to do this in a manner that promotes transparency and provides sufficient accuracy, completeness, comparability, and consistency.
The Transparent Monitoring project identified a set of criteria designed to overcome such challenges that are introduced by Book I. This Book II presents a collection of case studies demonstrating successful implementation of transparent monitoring approaches, based on experiences in Côte d’Ivoire, Ethiopia, Papua New Guinea, and Peru. These cases address specific needs identified by the countries, ranging from technical work on emission factors for forest conversion to palm oil plantations, via mapping of deforestation drivers based on remote sensing, improving communication of cacao mapping for different stakeholders, to making use of community-based monitoring information for forest restoration and deforestation alerts.
The case studies show that transparent monitoring approaches are not merely a technical requirement but a powerful enabler of meaningful climate action. By addressing existing challenges and building on the successes outlined in this report, countries can establish monitoring systems that drive transformative change. The path forward requires commitment, collaboration, and innovation, but the outcome will be more effective land sector policies, with benefits including enhanced resilience and contributing to containing climate change.
Transparent monitoring in practice: A guide to effective monitoring in the land sector. Book I – Background for understanding transparent monitoring approaches
Land management plays a crucial role in addressing climate change, which makes transparent monitoring essential. Countries have considerable flexibility in setting targets, defining the scope of the land sector, and reporting of greenhouse gas emissions and removals from it. They are, however, required to do this in a manner that promotes transparency and provides sufficient accuracy, completeness, comparability, and consistency.
An unprecedent amount of data is currently generated globally. It is available for assessing how land use and land management change over time and what the implications for greenhouse gas emissions and removals are. This data richness can serve as a solid foundation for generating high-quality products and services for tracking carbon stock changes. However, this large amount of information is also leading to confusion, with competing definitions and misinterpretation.
The Transparent Monitoring project identified a set of criteria designed to overcome such challenges and strengthen the effectiveness of monitoring greenhouse gas emissions from the land sector. These criteria are introduced in this Book I. Transparent monitoring approaches refer to datasets, tools, and portals that support countries’ needs in the land sector, by providing complementary data to what is mandated by their own monitoring systems.
By taking advantage of transparent monitoring approaches, countries can increase their capacities for monitoring and reporting GHG emissions and removals from the land sector and advance in the implementation of the Paris Agreement’s Enhanced Transparency Framework (ETF). Book II includes a collection of case studies demonstrating successful implementation of transparent monitoring approaches.
Are countries delivering on transparency? Key takeaways from the first Biennial Transparency Reports to the UNFCCC
Key messages
- The Paris Agreement requires Parties to submit Biennial Transparency Reports (BTRs) on greenhouse gas (GHG) emissions and removals. The first set of these reports was due by December 2024, however, as of February 2025, only 105 Parties had made their submissions—78 when counting the 27 countries of the European Union as a single Party—, while 90 submissions remained pending. Early submission was strongly correlated with country income level.
- This review applies a tailored screening and scoring framework to assess transparency in these first BTRs, focusing on two main dimensions – data and governance. The accuracy of data reporting was generally high– yet information on the Governance dimension in the reports remained limited referring to transparency, consistency, and comparability.
- To improve transparency in future BTRs, recommendations for data reporting include enhancing the quality of input data; adopting more advanced estimation methods and uncertainty analysis; improving inventory completeness across time series, emission categories and gases; and reducing the developing countries’ reliance on flexibility allowances in the reporting.
- Similarly, future governance reporting can be strengthened through standardized structured questionnaires or detailed checklists; better integration of institutional and stakeholder information; and greater recognition of non-state actor contributions.
- These improvements will require increased international cooperation, financial and technical support, and sustained capacity-building, particularly for developing country Parties.
Adding nuances: constructivist inquiry in agricultural R&D
Standard practice in agricultural research and development is for outside agents to define relevant variables to be researched or discussed or in community fora. This might be called “prspective” inquiry, due to the fact that parameters are pre-determined without consultation from other social actors. An alternative form of inquiry is gaining momentum which can trasform agricultural R & Dby making research questions and methods, as well as group learning, responsive to multiple realities.
