ArticleSatellite remote sensing-based forest resources assessment methods for effective management and sustainable development of forests by generation of information on forests and trees outside forest cover
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.Satellite based remote sensing methods have proved to be an effective and scientifically proven method for managing and conserving forest data and resources at periodic time intervals. The forest resources monitoring methods provide useful data to forest managers for sustainable forest management at different scale and forest management units. Over the years the scientific management of forest have been a subject globally discussed incorporating the role of environmentalist, conservationist and communities associated with the forest. It has been an unhidden fact that forests have suffered tremendous pressure in developing countries on the pretext of development. It is through effective monitoring and communication of forest information and knowledge that the concerned provincial governments are forced to take remedial measures for protecting the forests. Apart from the government owned forests, termed as Recorded Forest Areas(RFA) in India, Trees outside forests(TOF) are well acknowledged as an important component of forest resources. The ToF, which basically exist as block, linear and scattered plantations on earth are captured using LISS-III sensor of Indian Remote Sensing Satellite. For the national level scale mapping, all patches of area 1hectare and above are considered for estimation. For mapping of ToF patches of size between 0.1-1hectare, high resolution data from LISSIV sensor(5.8metres resolution) is analyzed. It has been now a well-established fact that trees outside RFAs, although in small proportion, contribute significantly to forest conservation and meeting the demand of people towards minor forest produce, firewood etc. The exercise on forest change detection using a hybrid method, is effective in identification of significant forest change. The assessment of forests and ToFs using satellite data and advance image processing tools may be helpful in effective management and long term sustainability of forests in developing countries.

ArticleThe farmer with agroforestry practices might be the “next forester”?
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.The main tropical Agro-Forestry Systems (AFS) are often complex, multi-stage and multi-species. Apart from home gardens intended for self-consumption, AFS are often based on a main crop with economic, or export value: rubber, coconut, cocoa, coffee, cloves, vanilla, damar, durian... with also local fruit trees, fast-growing fuelwood trees and timber trees for self-consumption or sale. This diversification in AFS focused on industrial crops, often comes after a period of deforestation since the end of the 19th century during the period of the colonial empires. Wood can also come from species used for services such as providing shade for coffee or cocoa trees. Wood species are also common in the local forest (Indonesia/Thailand), reflecting farmers' strategy of conserving local resources. In other cases, native species have almost entirely disappeared (e.g. clove AFS on the East Coast of Madagascar) in favor of introduced species. Sometime, the main crop is also a timber specie such a rubber (used for furniture), Durian, Litchi... Now that most forests have almost disappeared in central plains with easy access in Southeast Asia (with potential commercial value), timber from AFS is becoming a real challenge that depends mainly on tree tenure and local regulation. Today, the current demand for tropical wood has decreased considerably since the golden age of deforestation (1980/2010) due to resource depletion and a global demand towards products from dedicated plantations from Europe or elsewhere. The market has changed from a massive use of tropical timber for multiple purposes to a limited use for specific purposes. In this context, timber in AFS, often produced at marginal cost, can be an alternative to produce valuable timber. We consider in this sense that the farmer in tropical regions with agroforestry practices might be the “forester of the future”. Beside, AFS with timber might significantly contribute to positive externalities and eco- systemic services for a better sustainability. Keywords: agroforestry, forester, timber, diversification.

ArticleIndicators to assess the contributions of forests, trees, and agroforestry to food security and nutrition at national level
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.Forest, trees and agroforestry provide multiple contributions to Food Security and Nutrition (FSN), as shown by the GFEP report (2015) and the High-Level Panel of Experts on food security and nutrition report (HLPE 2017). However, there is currently no quantitative indicator to assess these contributions at national level. Here we propose options to fill this gap using four main themes to describe the contributions of forests, trees and agroforestry to food security and nutrition: • direct provision of food and feed; • provision of wood energy used for cooking food and boiling of water in developing countries which is critical for assimilation of nutrients and reduction of risks of diarrhea; • formal and informal employment, sources of income through sales of wood and non-wood orest products (NWFP) from forests, trees and agroforestry; • provision of ecosystem services that sustain food production through water and climate regulation; soil formation and protection, nutrient cycling, pest control and pollination. Some of these contributions, while well-known and described at local levels, like the contribution to livelihoods and to diets, are not included in national statistics. For others, particularly the contribution of ecosystem services to agricultural production, there are multiple dimensions which are difficult to measure even at a local scale. We will propose a set of indicators to track all of these contributions, using existing data that are available for all countries, such as fruit and nut consumption, woodfuel consumption, employment in forestry, and broader contribution of forests and trees to farming households through products, income and other benefits (e.g. ecosystem services, cultural value). We also suggest some ideas for how better more targeted data could be collected in the future. These proposals were discussed during the Expert Workshop in October 2019 in support of the CPF Joint Initiative on streamlining forest related reporting.
