Remote sensing algorithms for estimation of fractional vegetation cover using pure vegetation index values: A review
2020
Abstract Green fractional vegetation cover ( f c ) is an important phenotypic factor in the fields of agriculture, forestry, and ecology. Spatially explicit monitoring of f c via relative vegetation abundance (RA) algorithms, especially those based on scaled maximum/minimum vegetation index (VI) values, has been widely investigated in remote sensing research. Although many studies have explored the effectiveness of RA algorithms over the past 30 years, a literature review summarizing the corresponding theoretical background, issues, current state-of-the-art techniques, challenges, and prospects has not yet been published. The overall objective of the present study was to accomplish a compre…
Hyperspectral response of agronomic variables to background optical variability: Results of a numerical experiment
2022
Understanding how biophysical and biochemical variables contribute to the spectral characteristics of vegetation canopies is critical for their monitoring. Quantifying these contributions, however, remains difficult due to extraneous factors such as the spectral variability of canopy background materials, including soil/crop-residue moisture, soil-type, and non-photosynthetic vegetation (NPV). This study focused on exploring the spectral response of two important agronomic variables (1) leaf chlorophyll content (Cab ) and (2) leaf area index (LAI) under various canopy backgrounds through a global sensitivity analysis of wheat-like canopy spectra simulated using the physically-based PROSAIL …
The resilience of rural Ethiopian livelihoods : a case study from Hararghe zone, Eastern Ethiopia
2011
The purpose of this thesis was to examine the resilience and sustainability of rural Ethiopian livelihoods. The resilience and sustainability of livelihoods were studied in framework of food security. Preventing, coping and recovering from the shocks and stresses, in this case from drought and food insecurity, form an essential part of resilience and sustainability and therefore preventing and coping strategies were emphasized in this study. Also the effectiveness of the external aid was touched in empirical data because of its essential existence in the studied villages. The empirical data was gathered by interviewing people living in six rural villages in Hararghe zone, Eastern Ethiopia. …
The community conserved landscape of the Borana Oromo, Ethiopia
2011
Purpose - This paper seeks to describe an attempt to assess at the local level the progress that has been internationally achieved in recognition of community and indigenous rights, and of indigenous and community conserved areas. An action-research exercise was implemented in Ethiopia with a mobile indigenous people of evaluating customary as well as government-led governance of the environment, with the objective of strengthening the capacity of the Borana-Oromo to conserve their landscape. Design/methodology/approach - This paper is based on collaborative research implemented by the authors in 2002 while SOS Sahel Ethiopia was introducing collaborative forest management, and on a 2007 ac…
Social-ecological trends: managing the vulnerability of coastal fishing communities
2019
The loss of biodiversity, including the collapse of fish stocks, affects the vulnerability of social-ecological systems (SESs) and threatens local livelihoods. Incorporating community-centered indicators and SES drivers and exposures of change into coastal management can help anticipate and mitigate human and/or coastal vulnerability. We have proposed a new index to measure the social-ecological vulnerability of coastal fishing communities (Index of Coastal Vulnerability [ICV]) based on species, ecosystem, and social indicators. The ICV varies from 0 (no vulnerability) to 1 (very high vulnerability) and is composed of 3 components: species vulnerability, i.e., fish biological traits; ecosys…
Gendered battlefields : women in conflict, household livelihoods and post-conflict resilience building in Bawku, Ghana
2016
Master thesis development management UT503 - University of Agder 2016 This thesis mainly explores the gendered role of women in conflict and the livelihood implications of ethnic conflict on selected households. The USAID sustainable livelihood framework supplemented by the concepts of agency and empowerment served as the main theoretical points of discussion for this study. Further theoretical insights were drawn from Bujones et al (2013) factor analysis of resilience, in exploring opportunities for resilience building post-conflict in the study area. Using a case study of ethnic conflict between Kusasis and Mamprusis in Bawku (Ghana), responses were analysed to shed light on the perceived…
From sustainability to sustainable development: the role of food banks in food security in Uganda : a case study of the hunger project food bank - Mb…
2014
Master thesis in development management - University of Agder 2014 The purpose of this study is to identify the role the food bank plays for food security, sustainable livelihoods and building resilience to climate change among smallholder farmers in Uganda. The aim is to investigate how the food bank in Uganda operates in relation to food security and smallholder farmers. Much of the studies on food banks reveal that food banks are merely institutions that offer emergency food supplies to the hungry and are not agencies aiming at food security. These studies have, however, been based on the context of developed countries and no study has been conducted to establish the role of food banks i…
Community Resilience to Cyclone Disasters in Coastal Bangladesh
2016
Bangladesh is one of the poorest and most disaster-prone countries in the world. To address both problems simultaneously, sustainable livelihoods (SL) could be better connected with disaster risk reduction (DRR). For this purpose, one initiative implemented in Bangladesh is called the Vulnerability to Resilience (V2R) programme which ran from 2013 to 2016. This programme was primarily initiated and funded by the British Red Cross in a consortium with the Swedish Red Cross and the German Red Cross. This article presents the first evaluation of the V2R programme with three objectives. The first objective was to measure whether the selected communities have achieved community resilience charac…
