    L’année 2021 marque l’achèvement de la troisième année complète de mise en oeuvre de l’Initiative pour la restauration (TRI). Malgré les difficultés persistantes liées à la pandémie mondiale de covid-19, 2021 a vu des progrès encourageants. Les exigences de travail à domicile et autres restrictions ayant été levées, les participants aux projets ont pu retourner sur le terrain et mettre en oeuvre les analyses, les recommandations relatives aux stratégies et les plans de restauration et de gestion du paysage élaborés en 2020 pour accélérer les actions de restauration.

    As of 2017, SGP has awarded over 3,800 small grants to land degradation projects in over 120 countries, many of which are in regions with extreme levels of poverty and food insecurity across Africa and Latin America. Africa, in particular, is experiencing the highest population growth of the developing world, while being exposed and vulnerable to the rising impact from climate change.

    Deforestation, land degradation, and unsustainable land management threaten our lives and are responsible, both directly and indirectly, for many economic, social and environmental issues. In particular, countries in Northeast Asia face the growing threats of desertification, land degradation and drought (DLDD). In China, it is estimated that “more than 40 per cent of Chinese arable land is degraded” (China Daily 2014). “The annual cost of land degradation in Mongolia is estimated at 2.1 billion United States dollars (USD)” (UNCCD, 2018).

    The environment is deteriorating on a long-term basis in the Ejina River Basin in Inner Mongolia, China as a result of a water shortage. The shortage was caused by increased water use by industries and agriculture after 1992 along the upper part of the Ejina River. In 2002, the Chinese National Water Resource Agency instituted a water sharing plan which resulted in more water being released downstream to a region including the Kyoen Delta. The repartition will have an effect on vegetation increase in the Kyoen Delta area.

    In order to develop the original long-term cutting age management standard of Sugi (Cryptomeria japonica) plantaions in Nagasaki prefecture, site index curves and taper tables of Sugi plantations were created. 1) Site idex curves were revised up after 40-50 years on stand age, and rate of height growth was not decreased remarkably. 2) On the average relative stem curve, the determination coefficient of polynomial expression was 0.9799. 3) The new taper tables could be applied to trees whose height from 15 to 31 m and DBH from 15 to 50 cm.

    Vegetation mapping provides basic information for forest management and planning. In remote sensing research, the process of creating an accurate vegetation map is an important subject. Recently, there has been growing research interest in the object-oriented image classification techniques. The object-oriented image classification consists of multi-dimensional features including object features and thus requires multi-dimensional image classification approaches.

    The massive increase in demand for woodfuel for cooking caused by sudden influxes of refugees and other displaced people is usually the main driver of forest degradation and deforestation in displacement settings. It places enormous pressure on nearby forests and woodlands and is often a source of tension between the host and displaced communities. A lack of sufficient cooking fuel also has an impact on the nutrition and health of vulnerable people in such settings.
