This article analyses the effectiveness of humanitarian assistance in relation to the Sustainable Development Goals (SDGs) in the Minawao refugee camp in Cameroon, focusing on the social pillar of sustainable humanitarian. Established in 2013 to accommodate Nigerians fleeing the violence of Boko Haram, the camp now faces growing challenges related to the sustainability of assistance. Based on a mixed methodological approach, the analysis draws on data collected from humanitarian operators, refugees and the host community. The data was collected using tools such as participant observation, individual and group interviews, questionnaire surveys, mapping, documentary review, etc. Although essential infrastructure has been put in place, the study reveals that minimum humanitarian standards are not being met in several key sectors: food security, education, sanitation, shelter provision and Non Foods Items (NFIs). The lack of financial resources, combined with insufficient involvement by the Cameroonian government, has led to a gradual erosion of social protection for refugees. Maintaining assistance on a temporary basis compromises the integration of the SDGs into humanitarian operations. The article highlights the need for a forward-looking approach by humanitarian agencies, coordination between stakeholders and the involvement of new partners, including refugees, to guarantee their well-being and the achievement of the SDGs.

This study aimed to assess the influence of awareness and health habituation techniques, student management activities, the role of stakeholders, and the character of healthy living on health independence. The method used in this study is quantitative with descriptive test analysis techniques, partial t statistics and F test. This research was conducted in elementary schools in East Java Province, consisting of 92 elementary schools in 5 regions at East Java. Samples were taken using purposive techniques, and the number of samples was 348 people, consisting of principals, teachers and students. The results found that awareness and health habituation techniques have a significant influence on the character of healthy life of students, student management activities have a significant influence on the character of healthy life, the role of stakeholders has a significant influence on the character of healthy life, awareness and health habituation technique have a significant influence on health independence, student management activities have a significant influence on health independence, the role of stakeholders has a significant influence on health independence, the character of healthy living has a significant effect on health independence, and student management activities and the role of stakeholders have a significant effect on the character of healthy life, and have a significant impact on health independence.

Identify and diagnosis of homogenous units and separating them and eventually planning separately for each unit are considered the most principled way to manage units of forests and creating these trustable maps of forest’s types, plays important role in making optimum decisions for managing forest ecosystems in wide areas. Field method of circulation forest and Parcel explore to determine type of forest require to spend cost and much time. In recent years, providing these maps by using digital classification of remote sensing’s data has been noticed. The important tip to create these units is scale of map. To manage more accurate, it needs larger scale and more accurate maps. Purpose of this research is comparing observed classification of methods to recognize and determine type of forest by using data of Land Cover of Modis satellite with 1 kilometer resolution and on images of OLI sensor of LANDSAT satellite with 30 kilometers resolution by using vegetation indicators and also timely PCA and to create larger scale, better and more accurate resolution maps of homogenous units of forest. Eventually by using of verification, the best method was obtained to classify forest in Golestan province’s forest located on north-east of country.
