“…Arguably the most important ecosystem in terms of SOC stocks for Chile is that of the moorlands, which comprise a large area located on the Pacific coast of Patagonia where the landscape is fragmented into fjords and small islands (be- Luebert and Pliscoff (2006 tween 44 and 55 • S). The moorlands cover a significant section (9.1 %) of the country's area and are probably the largest soil carbon reservoir in Chile, with an almost continuous carpet of thick peat bog to a depth of 5 m in some places (Loisel and Yu, 2013;Minasny et al, 2019). Despite the importance of moorland soils, most of our knowledge of this ecosystem comes from the northern and eastern borders, whereas there is limited information about peat soils in remote areas of the western fjords (20 observations in this database).…”

Abstract. A critical aspect of predicting soil organic carbon (SOC) concentrations is the lack of available soil information; where information on soil characteristics is available, it is usually focused on regions of high agricultural interest. To date, in Chile, a large proportion of the SOC data have been collected in areas of intensive agricultural or forestry use; however, vast areas beyond these forms of land use have few or no soil data available. Here we present a new SOC database for the country, which is the result of an unprecedented national effort under the framework of the Global Soil Partnership. This partnership has helped build the largest database of SOC to date in Chile, named the Chilean Soil Organic Carbon database (CHLSOC), comprising 13 612 data points compiled from numerous sources, including unpublished and difficult-to-access data. The database will allow users to fill spatial gaps where no SOC estimates were publicly available previously. Presented values of SOC range from 6×10-5 % to 83.3 %, reflecting the variety of ecosystems that exist in Chile. The database has the potential to inform and test current models that predict SOC stocks and dynamics at larger spatial scales, thus enabling benefits from the richness of geochemical, topographic and climatic variability in Chile.

Abstract. One of the critical aspects in modelling soil organic carbon (SOC) predictions is the lack of access to soil information which is usually concentrated in regions of high agricultural interest. In Chile, most soil and SOC data to date is highly concentrated in 25 % of the territory that has intensive agricultural or forestry use. Vast areas beyond those forms of land use have few or no soil data available. Here, we present a new database of SOC for the country, which is the result of an unprecedented national effort under the frame of the Global Soil Partnership that help to build the largest database on SOC to date in Chile named “CHLSOC" comprising 13,612 data points. This dataset is the product of the compilation from numerous sources including unpublished and difficult to access data, allowing to fill numerous spatial gaps where no SOC estimates were publicly available before. The values of SOC compiled in CHLSOC range from 6×10−5 to 83.3 percent, reflecting the variety of ecosystems that exists in Chile. Profiting from the richness of geochemical, topographic and climatic variability in Chile, the dataset has the potential to inform and test models trying to predict SOC stocks and dynamics at larger spatial scales.

“…Although wetlands cover only about 6% of the global land surface [1,2], they support remarkable levels of biological diversity and provide a wide spectrum of ecological goods and services [3]. Among the diverse types of wetlands, peatlands stand out as extraordinary carbon sinks with estimated carbon stocks between 113 and 612 Pg (billion tonnes) globally [4,5].

“…Black dots show the locations of the pilot peatlands used for the preliminary extent assessment: from north to south, Cosapilla, Pomerape, Guallatire, Lirima, Tatio, and Machuca. Among the diverse types of wetlands, peatlands stand out as extraordinary carbon sinks with estimated carbon stocks between 113 and 612 Pg (billion tonnes) globally [4,5]. While peatlands are primarily found in the Northern Hemisphere boreal and subarctic regions [5], a unique peatland system, sustained by groundwater flows and snow-and glacier-melt, spans across the Central Andes Altiplano (~14°S-26°S)-the largest high-elevation, semiarid plateau in South America (>4000 m.a.s.l.)…”

A Multiscale Productivity Assessment of High Andean Peatlands across the Chilean Altiplano Using 31 Years of Landsat Imagery

et al. 2019

The high Andean peatlands, locally known as “bofedales”, are a unique type of wetland distributed across the high-elevation South American Altiplano plateau. This extensive peatland network stores significant amounts of carbon, regulates local and regional hydrological cycles, supports habitats for a variety of plant and animal species, and has provided critical water and forage resources for the livestock of the indigenous Aymara communities for thousands of years. Nevertheless, little is known about the productivity dynamics of the high Andean peatlands, particularly in the drier western Altiplano region bordering the Atacama desert. Here, we provide the first digital peatland inventory and multiscale productivity assessment for the entire western Altiplano (63,705 km2) using 31 years of Landsat data (about 9000 scenes) and a non-parametric approach for estimating phenological metrics. We identified 5665 peatland units, covering an area of 510 km2, and evaluated the spatiotemporal productivity patterns at the regional, peatland polygon, and individual pixel scales. The regional assessment shows that the peatland areas and peatlands with higher productivity are concentrated towards the northern part of our study region, which is consistent with the Altiplano north–south aridity gradient. Regional patterns further reveal that the last seven years (2011–2017) have been the most productive period over the past three decades. While individual pixels show contrasting patterns of reductions and gains in local productivity during the most recent time period, most of the study area has experienced increases in annual productivity, supporting the regional results. Our novel database can be used not only to explore future research questions related to the social, biological, and hydrological influences on peatland productivity patterns, but also to provide technical support for the sustainable development of livestock practices and conservation and water management policy in the Altiplano region.
