Characterizing Hawai‘i’s Natural Resources Management Sector

 

This report provides an update to the 2015 “Recent Trends in Hawai‘i’s Green Economy: Agriculture, Energy, and Natural Resource Management” publication, the second update since our original report in 2012. Hawai‘i’s natural resource management jobs were at least 4,697 in 2018, 33% higher than reported for 2014, which is equivalent to an annual growth rate of roughly 7%.

According to survey data, Hawai‘i’s natural resource management expenditures were at least $542 million in 2018, roughly equal to expenditures reported for 2014. Read more

Kaiāulu: Gathering Tides

Brown Bag Biography, the Department of Natural Resources and Environmental Management, and Sea Grant College Program Present:

September 19: “Kaiāulu: Gathering Tides.” Mehana Vaughan, Assistant Professor at UH Mānoa in the Dept. of Natural Resources and Environmental Management (NREM), Sea Grant College Program, and Hui ‘Āina Momona. Cosponsored by the Dept. of NREM and the Sea Grant College Program *this session will be held in KUYKENDALL 410 On the northeast coast of Kauaʻi, catch from small local reefs, and the sharing of this abundance, has sustained area kaiāulu (communities) for centuries, through tidal waves, hurricanes, burgeoning tourism, an influx of new residents, and loss of access of coastal lands, now private retreats for the ultra-wealthy. Building on interviews with more than sixty Hawaiian elders, leaders, and fisher men and fisher women, Kaiāulu shares their stories of enduring community efforts to cultivate fishing spots, maintain connection to family lands, reassert local governance rooted in ancestral values, and teach future generations to carry on. Mehana Blaich Vaughan grew up where the moku (districts) of Halele‘a and Ko‘olau meet on the island of Kaua‘i. Her home is on Kaua‘i with her husband, mother, and three children

Tracing the Curves of Bouncing Back: 
Data-Driven Methods for Assessing Disaster Resilience

Dr. Yi Qiang
Assistant Professor, Assistant Professor Department of Geography & Environment, University of Hawaiʻi at Mānoa

Considerable efforts have been made to understand resilience of human systems and develop useful metrics to measure it. Despite the extensive work on the conceptual frameworks, definitions, and case studies, quantitative assessment of resilience are still challenging due to the lack of empirical observations about human and infrastructure in real disaster events. In the era of big data, various types of sensors generate large volumes of data which can be used to monitor human activities at real-time and real-place. This presentation introduces a series of methods for assessing community and infrastructure resilience using various types of data including census data, remote sensing imageries, social media data and crowdsourced data. This research aims to fill the critical gap of empirical data and assessment methods for disaster resilience. The findings increase the understanding the complexity and dynamics of resilience and provide actionable information for disaster management, urban planning and sustainable development.

Rivero Castro Master's Thesis Defense: Examining the Effect of Zero-deforestation Commitment Characteristics on Land Cover Change and Spillover Effects

Title: Examining the Effect of Zero-deforestation Commitment Characteristics on Land Cover Change and Spillover Effects
Committee members:
Dr. Kimberly Carlson (Chair)
Dr. Rachael Garret
Dr. Linda Cox


Date: Friday, September 20, 2019
Time: 8:00 - 9:00 AM
Location: Sherman 103

 

Public concern over deforestation from tropical commodity crop expansion has led many corporations
that handle such commodities to adopt zero-deforestation commitments (ZDCs), which are pledges to stop
sourcing commodities produced on recently deforested or currently forested lands. Most ZDCs have yet to
be implemented, and they differ in implementation details including forest clearance cut-off date and land
covers that are off limits. Moreover, region-specific ZDCs may displace deforestation to areas not covered
by commitments. My research aims to investigate the effect of zero-deforestation commitments on tropical
land cover by addressing the following questions: 1) How might ZDC implementation affect geospatial
patterns of soy expansion? 2) How do changes in soy expansion patterns alter locations and patterns of
non-soy land cover change? 3) How does ZDC implementation date affect these outcomes? To answer
these questions, I built a land cover change simulation model for Brazil, Bolivia, Argentina, and Paraguay
from 2014-2030 that included a mechanism for simulating the effect of ZDC implementation by companies. I
evaluated land cover outcomes under different potential future scenarios, including no ZDCs, currently
pledged ZDCs, earlier implementation of these current ZDCs, and a soy moratorium in the Cerrado and
Gran Chaco ecoregions. In contrast to the No ZDC future, the current ZDC scenario reduced natural land
cover conversion by 3.2% while maintaining total national soy area, despite some displacement of natural
land conversion from the Cerrado and Gran Chaco regions to Brazilian Amazon and Argentinian Pampas
regions. Implementing these pledges about five years earlier (by 2020) resulted 357,000 ha (6.7%)
additional natural land cover in BBAP by 2030. Compared to the currently pledged ZDC scenario, the
Cerrado and Gran Chaco moratorium scenario reduced natural land cover loss by an additional 35,000 ha

(0.6%). These findings suggest that ZDCs may generate net preservation of natural land cover despite intra-
country leakage. Earlier ZDC implementation appears to be far more effective at conserving natural land

cover than increasing ZDC market share in later years.

Harrison Master's Thesis Defense: Targeted cattle grazing as a tool to reduce wildfire risk at Puʻu Waʻawaʻa Forest Reserve

Targeted cattle grazing as a tool to reduce wildfire risk at Puʻu Waʻawaʻa Forest Reserve

Committee Members: Dr. Clay Trauernicht (Chair) Dr. Linda Cox, Dr. Kimberly Burnett  

2:00-3:00 PM, Sherman 103

Monday September 23, 2019

 

The establishment of flammable invasive grasses in Hawaiʻi has created a grass-fire cycle that promotes fire and replaces native forest. Targeted livestock grazing provides a potential tool to reduce grassy fuels and fire risk at large spatial scales. In Hawaiʻi, cattle grazing can reduce invasive grass biomass, although little has been done on implementation. There is a long cultural heritage of cattle grazing in Hawaii, which is controversial due to historic contribution to forest degradation. Puʻu Waʻawaʻa Forest Reserve on Hawai’i Island contains one of the largest remnants of tropical dry forests in Hawai’i and is threatened by fire promoting invasive grasses. This study 1) Examines the role and challenges of grazing in response to dry forest management and conservation in Hawaiʻi using Puʻu Waʻawaʻa as a case study; 2) Investigate stakeholder values, preferences, concerns, and potential conflicts regarding Puʻu Waʻawaʻa fire management. Of special interest is the cost of production of cattle ranchers that graze in Puʻu Waʻawaʻa; and 3) assess stakeholder support for specific dry forest management strategies. This could aid land managers and policy makers in making better informed decisions and provide a model for other fire prone areas in Hawaʻi to utilize.
