Protecting Brazilian Amazon Indigenous Territories Reduces Atmospheric Particulates And Avoids Associated Health Impacts And Costs, Paula R. Priest, Florencia Sangermano, Allison Bailey, Victoria Bugni, María Del Carmen Villalobos-Segura, Nataly Pimiento-Quiroga, Peter Daszak, Carlos Zambrana-Torrelio

Geography

Indigenous territories are considered important for conservation, but little is known about their role in maintaining human health. Here we quantified the potential human health and economic benefits of protecting these territories in the Brazilian Amazon, by using cardiovascular and respiratory diseases cases, pollutant and forest cover data. Between 2010 and 2019, 1.68 tons of Particulate Matter of small size (PM2.5) were released every year, with negative effects for human health. A lower number of infections was also found in municipalities with more forested areas, and with a low level of fragmentation, which probably is related to the …

Land use is central to addressing sustainability issues, including biodiversity conservation, climate change, food security, poverty alleviation, and sustainable energy. In this paper, we synthesize knowledge accumulated in land system science, the integrated study of terrestrial social-ecological systems, into 10 hard truths that have strong, general, empirical support. These facts help to explain the challenges of achieving sustainability in land use and thus also point toward solutions. The 10 facts are as follows: 1) Meanings and values of land are socially constructed and contested; 2) land systems exhibit complex behaviors with abrupt, hard-to-predict changes; 3) irreversible changes and path dependence …


Correlational Analysis Of Mammals And Residential Land Use: Amherst, Ma, Ella Gutkowski Dec 2021

Correlational Analysis Of Mammals And Residential Land Use: Amherst, Ma, Ella Gutkowski

Massachusetts GIS Day

Mammal diversity varies in different types of land uses. Residential land use oftentimes interferes with the natural occurrence of mammal species. This study conducts a correlational analysis using camera trap data from Excel and land use data in GIS to uncover whether humans have disrupted mammal occurrence in residential land use areas in Amherst, MA. Results reveal that human activity in residential land use areas in Amherst did not strongly influence the occurrence of these mammals.

Ecosystem Carbon Balance In The Hawaiian Islands Under Different Scenarios Of Future Climate And Land Use Change, Paul C. Selmants, Benjamin M. Sleeter, Jinxun Liu, Tamara S. Wilson, Clay Trauernicht, Abby G. Frazier, Gregory P. Asner

Geography

The State of Hawai'i passed legislation to be carbon neutral by 2045, a goal that will partly depend on carbon sequestration by terrestrial ecosystems. However, there is considerable uncertainty surrounding the future direction and magnitude of the land carbon sink in the Hawaiian Islands. We used the Land Use and Carbon Scenario Simulator (LUCAS), a spatially explicit stochastic simulation model that integrates landscape change and carbon gain-loss, to assess how projected future changes in climate and land use will influence ecosystem carbon balance in the Hawaiian Islands under all combinations of two radiative forcing scenarios (RCPs 4.5 and 8.5) and …

In 1933, the United States federal government authorized the National Industrial Recovery Act to help the country recover from the Great Depression. Section 208, Title II of the National Industrial Recovery Act authorized the creation of subsistence homesteads to aid in the recovery of destitute rural families and the urban unemployed. Between 1933 and 1941, the United States federal government authorized the construction of 207 rural and urban resettlement communities to house impoverished farm families and unemployed urban workers. The projects were located throughout the United States, including in the territories of Hawaii, Alaska, Puerto Rico, and the U.S. Virgin …


If Watersheds Spoke: A Condition Analysis Of The Rio Tomebamba Watershed In Southern Ecuador Using Gis Analysis, Lenka G. Doskocil Apr 2020

If Watersheds Spoke: A Condition Analysis Of The Rio Tomebamba Watershed In Southern Ecuador Using Gis Analysis, Lenka G. Doskocil

Independent Study Project (ISP) Collection

Understanding processes and ecological threats occurring at the watershed level scale composes a critical piece of water resource conservation and management. This proves doubly true in areas such as the Ecuadorian highlands where water resources depend heavily on the hydrologic regulation capacities of páramo soils. This study examined watershed condition of the Rio Tomebamba watershed and existing habitat for Metallura baroni and Chibchanomys orcesi, two highly endemic species, within its boundaries. Watershed condition was determined based on a simple index that considered nine indicators of watershed health—converted land, impacted riparian zones, impermeable surfaces, water quality, fluvial habitat condition, riparian vegetation …

Global Pattern And Change Of Cropland Soil Organic Carbon During 1901-2010: Roles Of Climate, Atmospheric Chemistry, Land Use And Management, Wei Ren, Kamaljit Banger, Bo Tao, Jia Yang, Yawen Huang, Hanqin Tian

Plant and Soil Sciences Faculty Publications

Soil organic carbon (SOC) in croplands is a key property of soil quality for ensuring food security and agricultural sustainability, and also plays a central role in the global carbon (C) budget. When managed sustainably, soils may play a critical role in mitigating climate change by sequestering C and decreasing greenhouse gas emissions into the atmosphere. However, the magnitude and spatio-temporal patterns of global cropland SOC are far from well constrained due to high land surface heterogeneity, complicated mechanisms, and multiple influencing factors. Here, we use a process-based agroecosystem model (DLEM-Ag) in combination with diverse spatially-explicit gridded environmental data to …


Spatial And Topological Analysis Of Urban Land Cover Structure In New Orleans Using Multispectral Aerial Image And Lidar Data, Shuxian Liu Jan 2020

Spatial And Topological Analysis Of Urban Land Cover Structure In New Orleans Using Multispectral Aerial Image And Lidar Data, Shuxian Liu

LSU Master's Theses

Urban land use and land cover (LULC) mapping has been one of the major applications in remote sensing of the urban environment. Land cover refers to the biophysical materials at the surface of the earth (i.e. grass, trees, soils, concrete, water), while land use indicates the socio-economic function of the land (i.e., residential, industrial, commercial land uses). This study addresses the technical issue of how to computationally infer urban land use types based on the urban land cover structures from remote sensing data. In this research, a multispectral aerial image and high-resolution LiDAR topographic data have been integrated to investigate …


Electric Grid Decarbonization Pathways: Landscape Impacts, Policy Interactions, And The Need For Cooperation, Austin Wesley Thomas Jan 2020

Electric Grid Decarbonization Pathways: Landscape Impacts, Policy Interactions, And The Need For Cooperation, Austin Wesley Thomas

Graduate College Dissertations and Theses

Climate change has motivated governments around the world to ratify aggressive greenhouse gas emissions reduction targets. Meeting these targets will require improved energy efficiency, behavior changes, and energy system decarbonization. Many climate change and energy policy targets imply the deployment of large amounts of low carbon, renewable energy resources like wind turbines and solar photovoltaic (PV) panels but do not specify how these resources will be sited on the landscape. The relationships between weather conditions, terrain, land cover, existing electric grid infrastructure, and electricity consumers will govern how these wind and solar PV infrastructure configurations develop and how quickly they …

Toward A Normative Land Systems Science, Jonas Nielsen, Ariane De Bremond, Rinku Roy Chowdhury, Cecilie Friis, Graciela Metternicht, Patrick Meyfroidt, Darla Munroe, Unai Pascual, Allison Thomson

Geography

Science should provide solutions for societal transformations toward sustainability in the face of global environmental change. Land system science, as a systemic science focused on complex socio-ecological interactions around land use and associated trade-offs and synergies, is well placed to contribute to this agenda. This goal requires a stronger engagement with the normative implications of scientific practice, research topics, questions and results. We identify concerns as well as three concrete steps for land system science to more deeply contribute in normative issues. In particular, we encourage land system scientists to discuss explicitly the normative questions, values, perspectives and assumptions already …

Progress For Whom, Toward What? Progressive Politics And New York City’S Mandatory Inclusionary Housing, Samuel Stein Dec 2017

Progress For Whom, Toward What? Progressive Politics And New York City’S Mandatory Inclusionary Housing, Samuel Stein

Publications and Research

In both its historical Progressive Era roots and its contemporary manifestations, U.S. urban progressivism has evinced a contradictory tendency toward promoting the interests of capital and property while ostensibly protecting labor and tenants, thus producing policies that undermine its central claims. This article interrogates past and present appeals to urban progressive politics, particularly around housing and planning, and offers an in-depth case study of one of the most highly touted examples of the new urban progressivism: New York City’s recently adopted Mandatory Inclusionary Housing program. This case serves to identify the ways in which progressive rhetoric can disguise neoliberal policies. …


The Causal Effect Of Bus Rapid Transit On Changes In Transit Ridership, Orion T. Stewart, Anne Vernez Moudon, Brian E. Saelens Mar 2017

The Causal Effect Of Bus Rapid Transit On Changes In Transit Ridership, Orion T. Stewart, Anne Vernez Moudon, Brian E. Saelens

Journal of Public Transportation

Numerous studies have reported ridership increases along routes when Bus rapid transit (BRT) replaces conventional bus service, but these increases could be due simply to broader temporal trends in transit ridership. To address this limitation, we compared changes in ridership among routes where BRT was implemented to routes where BRT was planned or already existed in King County, Washington. Ridership was measured at 2010, 2013, and 2014. Ridership increased by 35% along routes where BRT was implemented from 2010 to 2013 compared to routes that maintained conventional bus service. Ridership increased by 29% along routes where BRT was implemented from …

High Carbon And Biodiversity Costs From Converting Africa's Wet Savannahs To Cropland, Timothy D. Searchinger, Lyndon Estes, Philip K. Thornton, Tim Beringer, An Notenbaert, Daniel Rubenstein, Ralph Heimlich, Rachel Licker, Mario Herrero May 2015

High Carbon And Biodiversity Costs From Converting Africa's Wet Savannahs To Cropland, Timothy D. Searchinger, Lyndon Estes, Philip K. Thornton, Tim Beringer, An Notenbaert, Daniel Rubenstein, Ralph Heimlich, Rachel Licker, Mario Herrero

Geography

Do the wet savannahs and shrublands of Africa provide a large reserve of potential croplands to produce food staples or bioenergy with low carbon and biodiversity costs? We find that only small percentages of these lands have meaningful potential to be low-carbon sources of maize (1/42%) or soybeans (9.5-11.5%), meaning that their conversion would release at least one-third less carbon per ton of crop than released on average for the production of those crops on existing croplands. Factoring in land-use change, less than 1% is likely to produce cellulosic ethanol that would meet European standards for greenhouse gas reductions. Biodiversity …
