ArticleSoil phosphorus behavior assessing under mixed stands vs pure
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.Increasing research has focused on mixed forest, found strong shreds of evidence that on ecosystem services provided by this stand over than pure forest. However, the studies to understand the relationship between soil nutrients, such as phosphorus -P-, and the effect of the type of forest are still deficient. It is widely known that P is an essential element for life and vegetation growth, despite that, its availability is limited in natural ecosystems. To this end, the superficial soil horizon was studied within three experimental triplets located in the Cantabrian Mountains and the Pyrenees. This research aimed to assess whether oak-pine (Quercus sp. and Pinus sylvestris) mixed forests influence differently than pure ones on the state and availability of soil phosphorus. Organic P, inorganic P, as well as P in soil microbial biomass phosphorus and enzymatic phosphatase activity were measured in 39 samples. Both chemical and biological variables were analyzed using the linear mixed two-factor method. Results suggested that the pH and location are the critical factors to determine P behavior. On the other hand, mixed forest stands showed an increase in their enzymatic activity, so we can conclude that species interaction is important for nutrient transformation.Keywords: Adaptive and integrated management, Climate change, Sustainable Forest management, Deforestation and forest degradation, Biodiversity conservationID: 3486443 -
ArticleValuing forest ecosystem services for local policy and planning in a forest management project site in the Philippines
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.In developing and implementing forest land use plans to attain sustainable forest governance, it is necessary to determine and value priority ecosystem services derived by society from forest and watershed ecosystems. This study aimed at estimating the value of four ecosystem services in a forest management project site in Nueva Vizcaya and Quirino provinces, Philippines: provision of water services, soil erosion control, carbon storage and sequestration capacity, and biodiversity conservation. The Integrated Valuation of Ecosystem Services and Tradeoffs (InVEST) tool was used to value water provision services (using a cost-based approach), soil erosion control (using replacement cost method), and carbon storage and sequestration capacity (using social cost of carbon). Contingent valuation method was used to determine the willingness to pay for biodiversity conservation. BAU and Development scenarios were used in determining changes in forest and other land uses in the site as well as estimating the value of the ecosystem services. Results show increases in forestland area and amounts of carbon storage and sequestration, decreasing annual water yield due to projected declining rainfall amount, and decrease in total annual soil loss. Mean WTP is PhP170 (~ US$ 3.50)/household/year. The estimated values of the four ecosystem services provide baseline information for local governments in crafting payment for ecosystem services strategies to help fund forest conservation.Keywords: policies, financial mechanisms, sustainable forest management, governanceID: 3486628 -
ArticleForest food ensures nutritional security of tribes of Kalahandi district, Odisha, India. A case study
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.Nutritional security is new era of challenges for entire world. change in climatic condition lead to reduction of nutrition quality of food that reduced concentration of proteins and minerals due to elevated carbon dioxide level. In India changes in food habit can lead to micronutrient deficiency or otherwise called as hidden hunger which now seen in most of the urban dwellers. The Present study carried out in Kalahandi north forest division of Kalahandi district Odisha .it was found that forest food was collected by Banjara, Bhatra, Munda, Paroja, saora, gonds, kondh, sabra tribes of kalahandi. The major forest foods that are collected from forests are edible bamboo shoots (Dendrocalamus strictus,Bambusa bamboos) edible wild mushroom ,Honey,Green leafy vagetables (Oxalis corniculate, Chenopodium album), wild turmeric,Tubers (Dioscorea hamiltonii), Tamarindus indica. Kusum seed(Schleichera oleosa), Mahua seed (Madhuca indica). The food items specific to summer include leaves and fruits of mango, kendu, jackfruit, amla, bel and tamarind among others. The average daily intake of uncultivated forest food ranges between 12% to 24%. The edible leaves available in the forest have very high content of pro-vitamin A (Beta Carotene), anti-oxidants and soluble protein. some of the tubers and mushrooms also have high iron, zinc, vitamins and anti-oxidant content that are vital for nutritional security. Bamboo shoots are considered as one of the useful health foods because of rich contents of proteins, carbohydrates, vitamins, fibres, minerals and very low fat. 17 amino acids eight of which are essential for human body. The Protein content in fresh Bamboo shoots, considered as nutraceutical can ranges between 1.49-4.04%. It is also found that bamboo shoots is most widely used food for tribal. Households consuming about 20% of their cooked food from the forest have no signs of malnutrition.Keywords: Nutritional security, bamboo, uncultivated, edible, tubers, NutraceuticalID: 3486683
