“…The number of deforested pixels that belong to the current grassland class were two fold those from croplands during the study period, but after 2017 the number of deforested pixels associated to the cropland class was larger than the deforested pixels associated to grasslands, indicating a possible change in the trend of these deforestation drivers. Annual deforestation values are especially high from 2006 to 2011, a period in which environmental protection agencies of the Pacific reported that 58.4% of the national timber was produced from natural stands [60]. It is also important to note the large effect that deforestation had during 2016-2017 on wetlands (Table 5), especially in 2016 when 123 km 2 were deforested.…”

Drivers of Forest Loss in a Megadiverse Hotspot on the Pacific Coast of Colombia

Tropical forests are disappearing at unprecedented rates, but the drivers behind this transformation are not always clear. This limits the decision-making processes and the effectiveness of forest management policies. In this paper, we address the extent and drivers of deforestation of the Choco biodiversity hotspot, which has not received much scientific attention despite its high levels of plant diversity and endemism. The climate is characterized by persistent cloud cover which is a challenge for land cover mapping from optical satellite imagery. By using Google Earth Engine to select pixels with minimal cloud content and applying a random forest classifier to Landsat and Sentinel data, we produced a wall-to-wall land cover map, enabling a diagnosis of the status and drivers of forest loss in the region. Analyses of these new maps together with information from illicit crops and alluvial mining uncovered the pressure over intact forests. According to Global Forest Change (GFC) data, 2324 km2 were deforested in this area from 2001 to 2018, reaching a maximum in 2016 and 2017. We found that 68% of the area is covered by broadleaf forests (67,473 km2) and 15% by shrublands (14,483 km2), the latter with enormous potential to promote restoration projects. This paper provides a new insight into the conservation of this exceptional forest with a discussion of the drivers of forest loss, where illicit crops and alluvial mining were found to be responsible for 60% of forest loss.

“…Si bien en esta sección hemos señalado lo que consideramos como algunas falencias normativas, consideramos que el problema en buena medida tiene que ver con la escasa aplicación de los marcos legales existentes (Servicio Nacional Forestal y de Fauna Silvestre [Serfor], 2019). Por otro lado, cabe señalar que para que la normativa ambiental sea cumplida de forma más efectiva, la legislación debe ser más sensible a las particularidades de las distintas regiones geográficas de Colombia (Rodríguez, Martínez, Villarraga & Ruíz, 2018).…”

“…With an area of approximately 34,270 km 2 and a population of approximately 1.9 million inhabitants, Huambo province is divided into 11 municipalities. It is 1700 m a.s.l., with a mean annual temperature of 20 • C, and annual rainfall ranges from 1200 to 1600 mm [47][48][49]. The climate is humid meso-thermal with dry winters and warm summers.…”

Defining Deforestation Patterns Using Satellite Images from 2000 and 2017: Assessment of Forest Management in Miombo Forests—A Case Study of Huambo Province in Angola

et al. 2018

A few studies have recently been published on changes in land use/land cover (LU/LC) of Angolan Miombo forests, however, none have attempted to offer forest management solutions for degraded Miombo forests. Landscapes are witness to past and present natural and social processes influencing the environment, where each period in the past leaves footprints on the landscape's development, which can be described by a continual decrease in forest area over time. The expansion of degraded areas from 2000 to 20017 began near urban areas where many Miombo forests have been eliminated or highly degraded, particularly in the southwest and northeast of the Huambo province. Large areas of degraded forests were observed along the Benguela railway (Caminho de ferro de Benguela). Our detailed analysis of the landcover map suggests that the impact has been devastating and there is no form of forest protection, which leads to unregulated exploitation. Descriptions of the Miombo forest dynamics are explained using height-diameter curves developed for different vegetation types that provide important insights about forest structures in the management zones. The height-diameter models differed for all vegetation types, and four management zones (MZ) were created based on a set of particular attributes. The vegetation types differed in each management zone, which included agricultural land and bare soil (MZ-E), grassland or savanna (MZ-C), open Miombo forests (MZ-B), and closed Miombo forests (Miombo forests). The four management zones were easily identified on the available maps and the height-diameter models developed represent a fundamental tool for future studies on forest planning.Sustainability 2019, 11, 98 2 of 20 agreed definition of forest degradation which makes the discussion more complex [3]. Deforestation is considered the result of the clearing of land for agriculture [4], both for the large-scale production of global commodities [5,6] and, in Africa, for small-scale production of food and cash crops [7]. Deforestation is among the most commonly studied phenomena in the frontier literature, as it is often associated with negative impacts on the global climate and biodiversity [6,8]. The scale of the environmental legacy of deforestation is dependent on both the magnitude and timing of historic land cover changes, not merely the snapshot of forest cover that is directly observable today [9][10][11][12][13][14]. The most important anthropogenic alterations of natural environments have always been the clearing of forests to establish cropland and pasture, and the exploitation of forests for fuelwood and construction materials. Analysing landscape changes due to past and present natural and social processes at different scales over time constitutes the departure point for landscape management because of close links between forests and physical attributes of the landscape. The mix of LC and LU (landscape composition) usually includes agricultural lands and native vegetation, and human dwellings in villages and urban areas. Th...
