Bulletin of Chinese Academy of Sciences (Chinese Version)

China is a mountainous country, with hills, mountains, and plateaus cover about two-thirds of its total land area. The vast area, huge population, rich natural resources, and great potential of development in mountain areas make them the most important “rear garden” supporting the sustainable development of the whole country. Nevertheless, China’s mountain areas are also prone to various kinds of natural disasters, and thus formed a scenario of high overlap between the high-risk zone of natural disasters and the lagging zone of social and economic development. And such scenario has caused significant waste of various related inputs, and becoming a …

Bulletin of Chinese Academy of Sciences (Chinese Version)

Affected by both increasing human activities and climate change, Yunnan Plateau lakes were faced with threats such as water level decreasing, water-body reducing, and severe pollution. Many indigenous species were endangered or even disappeared. The ecological restorations implemented since 1980s almost all used alien species. As an inevitable result, severe negative impacts from alien species were observed on the Plateau wetland ecosystem and indigenous species. To solve these problems, with the support of relevant projects, an innovative restoration mode mainly with indigenous flag-species “macrophytes – fishes – benthons – birds” was proposed. This innovative mode was implemented respectively in Dianchi …

Human Dimensions Of Woody Encroachment Management In Nebraska, Emily Rowen

School of Natural Resources: Dissertations, Theses, and Student Research

Woody plant encroachment (WPE) is a social-ecological problem that will challenge conservation professionals and agricultural producers to adapt their management strategies. This research first examined WPE from the perspective of individual conservation professionals through an online survey. Conservation professionals’ attitudes about adaptation to vegetation transitions, such as WPE, were of interest because these attitudes are one measure of how prepared this group is to respond to WPE. Hypothesized predictors of adaptation attitude were tested through linear regression modeling. These predictors included ecological change, observation of WPE, or risk perception. It was found that risk perception was the strongest predictor of …

The Perception Of Natural Resource Management In Nebraska: Efforts For Cross-Boundary Collaborative Management, Daniel Morales

School of Natural Resources: Dissertations, Theses, and Student Research

Nebraska’s agricultural landscapes are rapidly changing, affecting natural resources and their successful management. I utilized two surveys and scenario planning (Chapters 1: statewide survey, 2: local survey, and 3: scenario-planning workshop) to investigate attitudes and perceptions of natural resource management and cross-boundary collaboration. My first objective focused on determining what prevents Nebraskans from addressing natural resources challenges, considering demographics amongst generations and the type of areas they live in (rural versus urban). The second objective focused on whether landowners engaged with their community in managing natural resources. The third objective was to develop alternative future scenarios for the Denton Hills …

The Truth Behind Avocado Expansion In The Algarve: A Synthesis Of Public, Environmental Associations, And Government Perspectives And Response, Mandy Ausman

Independent Study Project (ISP) Collection

Avocado expansion has exponentially increased in the Algarve region of southern Portugal in recent years. The surge in expansion has provoked contention and discrepancy in the media regarding how and if avocado production can persist in the water-scarce region due to worsening drought conditions related to climate change coupled with the fruit’s significant water footprint. This paper aims to synthesize the arguments and response of the public, environmental associations, and government agencies to the expansion of avocado production in the water- scarce region of the Algarve, highlight the region’s current challenges of avocado expansion and water management regulation, and analyze …

The Flow Of Power: Addressing Asymmetric Flood Risk In The Upper Valley, Eric Vr Hryniewicz

Geography Undergraduate Senior Theses

Floods are the most damaging natural disasters in America. Land use change in upland watersheds can increase the probability and severity of floods (Bronstert, Niehoff, & Burger, 2002). When watersheds are divided by political and private property boundaries it leads to a misalignment of incentives in which downstream users lack recourse for upstream land use decisions contributing to flood risk. In this thesis, researchers interrogate the attributes of town officials and towns that determine what motivates town governments to act on flooding and what motivates and enables town officials to collaborate on planning and how do they collaborate in practice. …

Public-Ish, Aliah Werth

Masters Theses

Climate change affects public space, and architecture must establish tenets that prioritize pedestrians in this difficult era. Greywater re-use can be a mechanism for creating shade, and in turn, public space.

As heat waves grow more intense, the vast swaths of asphalt that connect commercial zones pose greater risks to public health and to urban vitality. This thesis records the typical material, spatial, and lived conditions of strip malls in urban heat islands, and demands more from infrastructure in public-ish space.

Heat violence weaves through Los Angeles’ built form. Parking space minimums, required setbacks, and height restrictions pull buildings away …

Status Quo Of Research And Suggestions On Reduction Of Non-Co2 Greenhouse Gas Emission From Chinese Farmland, Guangbin Zhang, Jing Ma, Hua Xu, Xiaoyuan Yan

Bulletin of Chinese Academy of Sciences (Chinese Version)

The mitigation of greenhouse gas (GHG) emissions is of great significance for controlling global warming. In 2014, the CH₄ and N₂O emissions from farmland accounted for 4.3% of the total GHG emissions in China. After the carbon peak target in 2030, fossil energy in China will be gradually replaced by clean energy, and then the contribution of CH₄ and N₂O emissions from farmland will be enlarged, leaving that the urgency and importance of emission reduction becomes increasingly prominent. However, available technologies of emission mitigation have not been fully adopted and promoted due to the …
