“…Physical variables (i.e., slope and major landform) were associated with stable forest. As has been shown previously, forests that are difficult to reach have low probability of conversion, as they are located at the top edge of mountains or along steep cliffs 80,[88][89][90] . These results highlight that although major land conversion is occurring in other areas of the country 16 , the HRL has experienced low human impact and may be especially vulnerable to forest changes if sustainable forest policies and management are not put in place.…”

Deforestation and forest degradation around the world endanger the functioning of ecosystems, climate stability, and conservation of biodiversity. We assessed the spatial and temporal dynamics of forest cover in Myanmar's Hkakabo Razi Landscape (HRL) to determine its integrity based on forest change and fragmentation patterns from 1989 to 2016. Over 80% of the HRL was covered by natural areas, from which forest was the most prevalent (around 60%). Between 1989 and 2016, forest cover declined at an annual rate of 0.225%. Forest degradation occurred mainly around the larger plains of putao and naung Mung, areas with relatively high human activity. Although the rate of forest interior loss was approximately 2 to 3 times larger than the rate of total forest loss, forest interior was prevalent with little fragmentation. physical and environmental variables were the main predictors of either remaining in the current land-cover class or transitioning to another class, although remaining in the current land cover was more likely than land conversion. the forests of the HRL have experienced low human impact and still constitute large tracts of contiguous forest interior. to ensure the protection of these large tracts of forest, sustainable forest policies and management should be implemented. Despite human practices and the unprecedented use of natural resources, forests are still widely distributed globally and cover around 30% of the Earth's surface 1,2. However, ongoing deforestation and forest degradation jeopardize the functioning of biogeochemical and hydrological cycles, climate stability and conservation of biodiversity 3-5. Net loss of forest area occurs largely in the tropics 6,7 and this forest loss continues to impact areas with particularly high conservation value 8,9. Tropical forests play a key role in the global carbon cycle and support more than half of the world's biodiversity 10. Industrial logging, agricultural expansion, fire, mining/resource extraction and urban growth have led to extraordinary loss of tropical forest 11,12. The amount of forest loss differs between continents 13 , with the highest levels occurring in South America and Asia 2. In Southeast Asia, Myanmar had the second highest rate of net forest loss between 1990 and 2015, trailing only Indonesia, with a loss rate of 546,000 ha y −1 between 2010 and 2015 1. Furthermore, this rate of forest loss represented a 25% increase since the 1990s. The driving forces behind the high rates of forest loss in Southeast Asia are logging and the global demand for crops such as oil palm, sugar, and wood fibre 14. Despite having the third largest annual forest loss in the world between 2010 and 2015 1 , Myanmar remains one of the most heavily forested countries in Southeast Asia 15,16. Myanmar is the second largest exporter of Teak (Tectona grandis), a valuable timber species, and much of the rural population continues to depend on forests to supplement their livelihoods 17. Some forest areas are used for small scale agroforestry and up to 77% of energ...

“…Es así que, Ochoa et al (2016) analizaron si tanto el clima y la topografía influyen en esta variable planteando el método de estimación de riesgo, en el que las áreas protegidas con amplia cobertura vegetal tienen un mejor potencial para contrarrestar la erosión, a diferencia de zonas donde las pendientes son pronunciadas, hay escasez de cobertura vegetal y lluvias esporádicas pero de alta intensidad, que junto con la profundidad del suelo, incrementan el riesgo por erosión (Correa et al, 2016) representando un peligro latente para las poblaciones que desarrollan actividades agrícolas cerca de estas zonas. Por lo que, la distribución espacial de los bosques permitirá conocer los índices de deforestación y pérdida de cobertura vegetal (Bax & Francesconi, 2018) evitando el incremento de estos peligros (Riquetti et al, 2020).…”

“…A nivel de Latinoamérica, los riesgos de inundación han aumentado en los últimos años, requiriendo la construcción de diques para minimizar los impactos en los cultivos representativos como: el azúcar, arroz, cebada, papa y trigo; pero que no garantizan su preservación a largo plazo, según indicó la Organización de las Naciones Unidas para la Alimentación y la Agricultura (FAO).

Mientras que, en Venezuela, Argentina y Chile las inundaciones o sequías se dan a pasos agigantados permitiendo incluso pronosticar que las actividades agrícolas desparecerán por completo en unos años (Villanueva, 2005).…”

“…The study area (Figure 1) includes Peru's Tropical Andes biodiversity hotspot (Mittermeier et al 2004) and all forested areas along the eastern flank of the Tropical Andes between approximately 500 and 3000 m.a.s.l. (Bax and Francesconi 2018), which are known to harbor many narrow ranged endemic species (Young et al 2011). This area is located between coordinates 3°4′37 South, 77°56′4 West, 18°2′54 South and 69°47′1 West, and corresponds to about 500,000 km 2 .…”

Land-use conflicts between biodiversity conservation and extractive industries in the Peruvian AndesThe International Center for Tropical Agriculture (CIAT) believes that open access contributes to its mission of reducing hunger and poverty, and improving human nutrition in the tropics through research aimed at increasing the eco-efficiency of agriculture.CIAT is committed to creating and sharing knowledge and information openly and globally. We do this through collaborative research as well as through the open sharing of our data, tools, and publications.
