An Insight into Application of Land Use Land Cover Analysis towards Sustainable Agriculture within Jhajjar District, Haryana

The increasing population, depletion of natural resources, semi-arid climatic and poor soil health conditions in Jhajjar district of Haryana have drawn major attention towards the changes in Land Use/Land Cover (LULC). The region's increasing population is mainly dependent upon the agrarian economy; thus, sustainable agricultural production is a major thrust area of research. The present study analyses the LULC changes in the area during two decades 2000 – 2020, using remote sensing and Geographic Information System (GIS). Landsat satellite images (Landsat-7 and Landsat-8 satellites) for 2000 and 2020 were analyzed for mixed classification based on unsupervised classification followed by supervised classification. The study area has experienced an increase in agricultural land, surface water bodies and built-up land by 16.89%, 79.73% and 56.41%, respectively. There is a decrease in barren land and fallow land by 48.53% and 36.97%, respectively, as per the five major LULC classes. The LULC analysis indicates an increase in built-up land, which is responsible for controlling agricultural productivity and unsustainable agricultural activities. The study provides a comprehensive understanding of the land use trajectory in a specific region in two decades and associated unsustainable changes in the agrarian economy through pressure on the increase in agricultural production and conversion of land mass into croplands. It also signifies climate-resilient agriculture and the management of sustainable agriculture

Quality of life and physical function in adults treated with intensive chemotherapy for acute myeloid leukemia improve over time independent of age

Artículo de publicación ISIObjectives: Intensive chemotherapy (IC) is the primary treatment of acute myeloid leukemia (AML) but is associated with significant toxicity, particularly in older adults. We characterized the impact of AML and its treatment on quality of life (QOL) and physical function in younger (age 18-59) and older (age 60+) patients with AML over 1 year from diagnosis. Materials and Methods: AML patients undergoing IC without stem-cell transplant at two tertiary care centers were enrolled in a prospective, longitudinal study. Assessments were done pre-IC and at 7 time points over the next year. QOL, fatigue, and physical performance (grip strength, 2-minute walk test (2MWT), timed chair stands) were measured in all patients whereas daily function was measured only in older patients. Data were analyzed using mixed effects regression models. Results: 237 patients were recruited (140 younger and 97 older, 56% male). One-year survival was 79% and 60% among younger and older patients, respectively. For patients in remission, global QOL and fatigue improved significantly over time (p < 0.001 for both); trends were similar between older and younger patients. Grip strength did not change over time (p = 0.58) whereas both the 2MWT (p < 0.001) and timed chair stands (p < 0.001) improved significantly. Daily function improved significantly over time (p = 0.003). Conclusions: Survivors of AML in remission after IC achieve significant improvements in QOL, fatigue, and physical function over time with similar trajectories for older and younger patients. These data suggest that appropriately selected older patients do well following IC.Canadian Institutes of Health Research 86697 Leukemia and Lymphoma Society 6220-1
