Can wood-based BECCS really deliver the negative emissions it promises? Our paper in Nature Sustainability provides a full carbon accounting of forest-based BECCS, from harvest and regrowth to processing, combustion, and carbon capture. It shows that once all system-wide carbon losses are counted, wood-based BECCS often emits more than natural gas with CCS, making meaningful climate benefits much harder to achieve than commonly assumed.

On April 10–11, we hosted a Nature-based Solution (NbS) Exchange Workshop at HKU. On Day 1, our visiting guest Simon Racé shared case studies from Europe, followed by presentations from colleagues, Katie Chick and Darwin Leung, at the HKU Centre for Civil Society and Governance (CCSG) on their ongoing pilot projects. On Day 2, the exchange continued with a field trip to Lai Chi Wo, where participants visited local project sites and discussed opportunities for applying NbS in Hong Kong’s rural landscapes.

How can we build the homes the world needs without destroying habitats on our planet? Our paper in Communications Sustainability evaluates realistic pathways to decarbonize construction materials by 2050. It shows that while sustainable biomass supply is constrained for engineered bio-based products, low-carbon concrete can scale globally, offering a practical route to deliver housing and cut embodied carbon.

We recently visited the Lai Chi Wo coffee plantation to learn how agroforestry is being practiced in Hong Kong. Over the past decade, Lai Chi Wo’s coffee plantation has grown from a small pilot into a signature local agroforestry effort—rehabilitating abandoned terraces, expanding plantings, and learning-by-doing from early trial harvests.

This Nature reply continues an important conversation on forest carbon accounting. We clarify key assumptions and methodological choices about the carbon implications of wood harvesting and forest management. The goal is to keep the debate constructive and transparent—so evidence can better inform forest policy and climate solutions.

Why is the planet “greening” and how much of it is actually driven by real changes in vegetation cover? In our recent analysis in Nature Communications, we combine satellite observations with a data-driven attribution framework to quantify how vegetation cover changes global leaf area index (LAI) trends since the 1980s. We find vegetation cover change increasingly explains observed LAI, with tree-cover gains in the Northern Hemisphere partly offset by tropical deforestation.

Staying within Earth’s environmental limits won’t happen with incremental tweaks. This global comparison study shows we likely need ambitious, combined interventions—including lower animal-source-food diets, major improvements in farming efficiency and nutrient management, and reductions in overconsumption and food waste—to meaningfully cut the risk of crossing key planetary thresholds.

We are pleased to welcome Shihan Wang to APLUS. He is deeply curious about the full spectrum of processes linking satellite observations and ground-based measurements.

Liqing conducted a short-term research visit at the Department of Earth System Science at Tsinghua University.

Liqing visited the mountain forest carbon-sink ecological site in Longyan (Fujian Province), a cutting-edge flux-tower platform designed specifically for complex mountainous terrain. The site features two fixed towers spanning a valley, plus a cable-driven moving tower/platform that traverses between them (super cool!). This allows near-continuous measurements of CO₂, water vapor, energy and related exchanges across topographic gradients.

This analysis in Nature Geoscience finds that preserving woody debris (e.g., logging residues, mill wastes) by placing it deeper in soils could extend carbon residence times and enable CO₂ removal potential in managed forests.

How do our diets ripple through water systems? Our paper in Nature Food links shifts in meat consumption to changes in agricultural nutrient pollution, showing that dietary change can be a powerful lever for improving groundwater quality alongside farm management. It adds a fresh “water-quality” dimension to food-system sustainability conversations.

We were delighted to welcome distinguished Princeton research scholar Tim Searchinger to APLUS. During his visit, we hosted a focused workshop on Sustainable Agriculture in China, bringing together Tim with Professors Zhenzhong Zeng, Yixin Guo, and Peng Zhu for an engaging exchange on research frontiers, policy relevance, and opportunities for collaboration.

Drought indices often assume the land surface is “uniform,” but real landscapes aren’t. Our paper proposes an enhanced SPEI approach that integrates land-surface and vegetation characteristics into estimating evaporative demand, improving drought monitoring, especially in the forests where surface properties strongly shape how quickly moisture is pulled from soils and vegetation.
