Abstract:The integration of economic development and environmental management has become a major concern for society, businesses and governments, especially during the past century. A desk review was carried out to examine the various forest resource management systems used in Ethiopia over the past half century. Forest resources in Ethiopia have been managed with different intentions and motivations at different times; these management systems can be broadly categorized by prominent resource management paradigms, like… Show more
“…The soil samples for %C were air -dried and analyzed using Walkley-Black method 27 . A SOC stock (Mg C ha -1 ) was determined through fixed depth method by multiplying of %C, bulk density (g/cm 3 ), soil organic C fraction (%C) and soil depth (cm)) 25,28 . % 100…”

“…The country's forest land, on the other hand, has been rapidly shrinking over time. From 1990 to 2000, forest losses were estimated to 8.3 million hectares, and from 2000 to 2010, 5.2 million hectares 3 . This day major parts of the remaining natural forests which harbor high biodiversity are located on steep slopes at high altitude and in the remote southern and southwestern parts of the country.…”
Background Gura-Ferda forest is one of the Afromontane rainforests in the southwestern region of Ethiopia. However, since 1984, large parts of this forest have become increasingly disturbed and fragmented due to forest conversion into forest farm interface and farmlands. The study was conducted to assess changes of woody species diversity and carbon stock in association with the conversion of natural forest to forest farm interface and farmlands. Methods Data were collected from natural forest, forest farm interface and farmland which are historically forest lands before 1984. A total of 90 nested plots (20m×20m for natural forest and forest farm interface; 50m*100m for farmland)) were established for inventory of woody species. Three 1m×1m subplots were established to collect litter and soil samples. A total of 180 soil samples were collected. The total carbon stocks were estimated by summing carbon stock in the biomass and soil (0-60 cm depth). Results Results showed that Shannon-Wiener diversity (H’) in forest farm interface (H’ = 1.42±0.49) is significantly lower than that of natural forest (H’ = 2.72±0.31) but significantly higher than farmland (H’ = 1.08±0.57). The total carbon stocks of natural forest (388.54±161.63 Mg C ha-1) were approximately 1.53 and 2.67 times higher than that of forest farm interface (252.95±41.86 Mg C ha-1) and farmland (145.58±25.94 Mg C ha-1). Conclusion Our study revealed that along the conversion gradient of natural forest to forest farm interface and farmland there was a significant change of woody species diversity and carbon stocks.

“…Policy is a guiding principle of major goals and activities to specific measures prepared by the governing bodies. Various natural resources and watershed related policies and strategies were prepared by the government in different periods [27,30,47,46]. However, there is still lack of properly implementation of the policy and strategies according to it were instructed on the document at site or lower level of administrations [34,48].…”

“…However, through time to time, there has been a dramatic decline in forested area in the country. Accordingly, from 1990 to 2000 and from 2000 to 2010, forest losses were estimated at 8.3 million ha and 5.2 million ha respectively (Eshetu, 2014). These days major parts of the remaining natural forests which harbor high biodiversity are located on steep slopes at high altitude and in the remote southern and southwestern parts of the country.…”
Background: Gura-Ferda forest is one of the Afromontane rainforests in the southwestern region of Ethiopia. However, since 1984, large parts of this forest have become increasingly disturbed and fragmented due to forest conversion into forest farm interface and farmlands. The study was conducted to assess changes of woody species diversity and carbon stock in association with the conversion of natural forest to forest farm interface and farmlands. Methods: Data were collected from natural forest, forest farm interface and farmland which are historically forest lands before 1984. A total of 90 nested plots (20m×20m for natural forest and forest farm interface; 50m*100m for farmland)) were established for inventory of woody species. Three 1m×1m subplots were established to collect litter and soil samples. A total of 180 soil samples were collected. The total carbon stocks were estimated by summing carbon stock in the biomass and soil (0-60 cm depth). Results: Results showed that Shannon-Wiener diversity (H’) in forest farm interface (H’ = 1.57) is relatively lower than that of natural forest (H’ = 3.33) but higher than farmland (H’ = 1.42). The total carbon stocks of natural forest were approximately 1.21 and 2.54 times higher than that of forest farm interface and farmland. Conclusion: Our study revealed that the changes of Natural Forest to Forest Farm Interface and Farmland have effects on the diversity of woody species and carbon stocks.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
