Jurnal Geografi Lingkungan Tropik (Journal of Geography of Tropical Environments)

Seawater intrusion can increase soil salinity, which occurs due to flooding, evaporation, and land cover changes in coastal areas. This research aims to map and observe the characteristics of seawater intrusion in Way Urang, Kalianda, South Lampung, using Dual-polarization of Sentinel-1 SAR imagery with VV, VH, VV+VH, and (VV+VH)/2 polarization. There were 28 samples used in this research which were divided into two types, GCP (ground control point) and ICP (independent check point). GCP samples are used to create a seawater intrusion estimation model using the regression method, while ICP samples are used to test the validation model using the …

Assessing Compliance To Water Resources And Reconstruction Framework During Post-Conflict Reconstruction Borno State, Muritala Olaniyi Oke Dr

Journal of African Conflicts and Peace Studies

Northeast and northwest of Nigeria have, as a result of activities of Boko Haram, bandit and kidnappers, had their public and private properties destroyed. Governments and other stakeholders, upon some successes of the military, have started post-conflict reconstruction to rebuild the war-torn urban and rural communities with the provision of water taking the center stage. This paper looks at the utilisation of Water Resources and a Reconstruction framework for integrating water projects into reconstruction processes. This paper rests on the argument that water projects during reconstruction should not be handled as “normal” water projects and that a more culturally and …

Reducing Food Scarcity: The Benefits Of Urban Farming, S.A. Claudell, Emilio Mejia

Journal of Nonprofit Innovation

Urban farming can enhance the lives of communities and help reduce food scarcity. This paper presents a conceptual prototype of an efficient urban farming community that can be scaled for a single apartment building or an entire community across all global geoeconomics regions, including densely populated cities and rural, developing towns and communities. When deployed in coordination with smart crop choices, local farm support, and efficient transportation then the result isn’t just sustainability, but also increasing fresh produce accessibility, optimizing nutritional value, eliminating the use of ‘forever chemicals’, reducing transportation costs, and fostering global environmental benefits.

Smallholder Farmer Resilience As A Pillar Of Climate-Smart Agriculture: A Review, Michael B. Madin Mr, Daniel Kweku B. Inkoom Professor, Charles A. Bamfo Jr

Journal of Environmental Sustainability

This systematic review synthesizes and assesses scientific literature publications (n=42), to identify and depict the focus of climate change adaptations and resilience research on smallholder farmers in the savannah ecological zone (SAZ). We found substantive studies providing evidence of climate impacts, with adverse consequences on both human and environmental systems. Adaptive actions are being employed to manage the changing conditions as response to climate impacts. Notably, most research efforts are currently restricted to impacts on adaptation, food security, and vulnerability, with a very rare focus on climate resilience and the effects of adaptive actions. Hence, the possible maladaptation outcomes, which …

Statistical Modeling To Predict The Hydrological Characteristics Of The Sub- Basins Of The Northern Jordan Rift Valley

Journal of the Faculty of Arts (JFA)

Morphometric parameters are an applicable method to understand the hydrological system of water drainage basins. To determine the capabilities of sub-basins, morphometric analysis was adopted, using the linear, areal, drainage network, formality, and relief variables of the drainage basin. Moreover, remote sensing and GIS have been proven to be efficient tools for identifying morphological parameters. The morphological parameters were calculated from the digital elevation model (DEM) file with a 30 m resolution obtained from U.S. Geological Survey (USGS). Also, using algorithms formulas, represented by the SCS method for runoff estimation, equations for morphometric variables, and equations for hydrological variables estimation. …

Nashville-Basin Tornadoes: Using Storm Types To Elucidate The Local Climatology And Forecasting Challenges, Morgan Steckler, Kelsey Ellis

Pursuit - The Journal of Undergraduate Research at The University of Tennessee

Early 3 March 2020 was a devastating night for many middle Tennessee residents. A strong EF-3 tornado tore through Nashville at 65 mph, and another EF-4 killed 18 in Baxter and Cookeville alone. Residents of the Southeastern United States are particularly vulnerable to tornadoes. This study aims to better understand local forecasting challenges by looking at the types of storms that produce tornadoes. Storm types, also known as convective modes, divide tornado-producing storms into categories by length, shape, multiplicity, and intensity. Distinguishing storms by these modes allows for a broader understanding of their occurrences and impacts. This study specifically evaluates …

Blue Growth: A Transitions Approach To Developing Sustainable Pathways, Christina Kelly, Ben Mcateer, Frances Fahy, Liam Carr, Daniel Norton, Desiree Farrell, Rebecca Corless, Stephen Hynes, Zacharoula Kyriazi, Agnès Marhadour, Regis Kalaydjian, Wesley Flannery

Journal of Ocean and Coastal Economics

The sustainable management of Blue Growth is an urgent issue for coastal states. Marine industries have rapidly expanded over the last two decades and this is projected to continue with the European Green Deal and post-COVID economic recovery policies. The intensification of Blue Growth could have adverse socio-ecological implications and must, therefore, be managed in terms of sustainability, natural resource boundaries, and coastal community well-being. Managing Blue Growth in a sustainable manner however, is challenging due to the longstanding inefficiencies and inertia of existing marine governance regimes. Adopting a transitions approach has been advanced as a way of steering regime …
