Ancient Maya canals and fields show early and extensive impacts on tropical forests

New evidence in Belize shows the ancient Maya responded to population and environmental pressures by creating massive agricultural features in wetlands, potentially increasing atmospheric CO2 and methane through burn events and farming, according to geographical research....

The Nature Conservancy, Amazon Launch Fund to Scale Up Natural Climate Solutions

The Nature Conservancy and Amazon have launched a project, committing USD 100 million to restore and protect the world’s forests, wetlands and peatlands. The ‘Right Now Climate Fund’ will contribute to Amazon’s efforts to achieve net zero carbon emissions across its business ten years ahead of the 2050 target set in the Paris Agreement....

Forest tenure, wetlands and more: CIFOR at IUFRO

The air you breathe, the water you drink, the food you eat, they all depend on the world’s forests. You may not aware of it, but forests and trees provide a wide range of benefits to people, both in rural communities and urban centers worldwide. The benefits span from environmental, social and even cultural aspects. Thus, the conservation and sustainable management of forests and trees are close...

Hydrogeomorphic controls on soil carbon composition in two classes of subalpine wetlands

Wetlands play a vital role in terrestrial carbon (C) sequestration, but the sensitivity of their C stocks to disturbance remains uncertain, requiring enhanced understanding of the processes that govern C storage and removal. The unique conditions in wetlands from different hydrogeomorphic (HGM) classes likely regulate the cycling, storage and vulnerabilities of wetland soil C stocks. To determine ...

Mapping Mountain Peatlands and Wet Meadows Using Multi-Date, Multi-Sensor Remote Sensing in the Cordillera Blanca, Peru

Wetlands (called bofedales in the Andes of Peru) are abundant and important components of many mountain ecosystems across the globe. They provide many benefits including water storage, high quality habitat, pasture, nutrient sinks and transformations, and carbon storage. The remote and rugged setting of mountain wetlands creates challenges for mapping, typically leading to misclassification and un...

Topographic Metrics for Improved Mapping of Forested Wetlands

We investigated the predictive strength of forested wetland maps produced using digital elevation models (DEMs) derived from Light Detection and Ranging (LiDAR) data and multiple topographic metrics, including multiple topographic wetness indices (TWIs), a TWI enhanced to incorporate information on water outlets, normalized relief, and hybrid TWI/relief in the Coastal Plain of Maryland. LiDAR DEM ...

Koondrook-Perricoota State forests replenishment

Up to 4500 hectares of red gum forest, fringing creeks, wetland and habitat will be replenished over the next 60 days thanks to a planned watering event in the Koondrook and Perricoota State Forests. Source: Timberbiz Forestry Corporation of NSW’s The Living Murray Program Manager for Koondrook-Perricoota Linda Broekman said the watering was critical to protect habitat and improve the health of ...

Long-term water Table dynamics of forested wetlands: Drivers and their effects on wetland hydrology in the southeastern Atlantic Coastal Plain

Sustainable management of forested wetlands requires an understanding of water Table (WT) dynamics affected by rainfall and evapotranspiration (ET) and management practices, designed to sustain water quality, quantity, and ecosystem functions and productivity. In this paper analysis of long-term data from four drained and six undrained sites on coastal forested wetlands showed that their growing s...

Tidal forested wetlands: mechanisms, threats, and management tools

Tidally influenced coastal forested wetlands can be divided into two broad categories, mangroves and freshwater forested wetlands. These forested wetlands perform valuable ecosystem services, and both are endangered by threats of sea level rise and land use. Understanding the mechanisms that control the distribution of tidal forests has been greatly enhanced by innovation in measurement and modeli...

Measuring mangrove carbon loss and gain in deltas

Demand for mangrove forest resources has led to a steady decline in mangrove area over the past century. Land conversions in the form of agriculture, aquaculture and urbanization account for much of the deforestation of mangrove wetlands. However, natural processes at the transition zone between land and ocean can also rapidly change mangrove spread. In this study, we applied a robust field-based ...

Terrestrial wetlands

1. The assessment of terrestrial wetland carbon stocks has improved greatly since the First State of the Carbon Cycle Report (CCSP 2007) because of recent national inventories and the development of a U.S. soils database. Terrestrial wetlands in North America encompass an estimated 2.2 million km2, which constitutes about 37% of the global wetland area, with a soil and vegetation carbon pool of ab...

How much blue carbon loss and recovery following land-use change?

How much blue carbon loss and recovery following land-use change? Comparing global systematic review and field assessments from Indonesian Papua mangroves The coastal mangrove forest is one of the blue carbon ecosystems and most efficient carbon sink ecosystems on earth. However, these carbon-dense wetlands are currently under pressure from major land-use and land-cover changes (LULCCs), wh...
