Spatial Tools for Integrated and Inclusive Landscape Governance: Toward a New Research Agenda
15. Oktober 2021
Abstract Participatory spatial tools—community mapping, PGIS, and others—find increasing resonance among research and non-governmental organizations to make stakeholder claims and community perspectives explicit for more inclusive landscape governance. In this paper, we situate the use of participatory spatial tools in debates on integrated landscape approaches and inclusive development. We show that using such spatial tools is not new but argue that their application for inclusive landscape governance requires a new research agenda that focuses on expanding the scope...
Farm-Level Effects of Emissions Tax and Adjustable Drainage on Peatlands
14. Oktober 2021
Abstract Drained agricultural peatlands emit significantly higher amounts of greenhouse gas (GHG) emissions per hectare than mineral soils. GHG abatement costs for representative cereals (CF) and dairy (DF) farms in southwestern Finland were estimated by integrating an emission-based tax together with an option to invest in a subsidized adjustable drainage system on peat soils in a farm-level dynamic optimization model. With an average 10% share of peat soils from overall farm area, emissions tax rates over 15 (CF) and 19 (DF) €/tCO2e triggered adjustable drainage...
Have farmers had enough of experts?
11. Oktober 2021
Abstract The exponential rise of information available means we can now, in theory, access knowledge on almost any question we ask. However, as the amount of unverified information increases, so too does the challenge in deciding which information to trust. Farmers, when learning about agricultural innovations, have historically relied on in-person advice from traditional ‘experts’, such as agricultural advisers, to inform farm management. As more farmers go online for information, it is not clear whether they are now using digital information to corroborate in-person...

SARS-CoV-2 in wastewater from Mexico City used for irrigation in the Mezquital Valley: quantification and modeling of geographic dispersion
01. Oktober 2021
Abstract Quantification of SARS-CoV-2 in urban wastewaters has emerged as a cheap, efficient strategy to follow trends of active COVID-19 cases in populations. Moreover, mathematical models have been developed that allow the prediction of active cases following the temporal patterns of viral loads in wastewaters. In Mexico, no systematic efforts have been reported in the use of these strategies. In this work, we quantified SARS-CoV-2 in rivers and irrigation canals in the Mezquital Valley, Hidalgo, an agricultural region where wastewater from Mexico City is distributed...
Shelterbelt Management Practices for Maximized Ecosystem Carbon Stocks on Agricultural Landscapes in Saskatchewan, Canada
01. Oktober 2021
Abstract There is a significant knowledge gap in the area of management of the vast shelterbelt network currently existing on agricultural lands in Canada and across the world. Throughout eight decades of shelterbelt planting in Saskatchewan, Canada, there are no available records of shelterbelt management practices used by land managers, such as herbicides (H), fertilizers (F), irrigation (I), or tillage (T) applications, collectively referred to as HFIT management. The main objective of this large-scale study was to quantify the effects of HFIT management on...
Assessing the Accuracy of Farmers’ Nutrient Loss Risk Perceptions
01. Oktober 2021
Abstract Use of nutrient management practices to reduce nutrient loss from agriculture and its associated water quality consequences, including hypoxia and eutrophication, is widely encouraged. However, little is known about which factors influence farmers’ risk perceptions associated with nutrient loss, and thus possibly influence their decisions to adopt such practices. To determine which factors were associated with relative “accuracy” of nutrient loss–associated risk perceptions, specific farm field management information was used as inputs to a Soil and...
More Than Just a Trend: Integrating Population Viability Models to Improve Conservation Management of Colonial Waterbirds
01. Oktober 2021
Abstract Waterbird populations in eastern Australia have been declining over the past 35 years primarily due to water resource development and resultant changes to natural river flows and flooding. To mitigate these impacts there is an increased allocation of water for the environment, including waterbird populations. We used population viability models to identify the frequency of breeding events required to reverse the trend and achieve long-term species’ management objectives. We found that the population size of straw-necked ibis was primarily dictated by the...
Characterizing Trophic State in Tropical/Subtropical Reservoirs: Deviations among Indexes in the Lower Latitudes
01. Oktober 2021
Abstract Trophic state indexes (TSI) guide management strategies regarding eutrophication control worldwide. Such indexes usually consider chlorophyll-a (Chl-a), total phosphorus (TP), and Secchi disk depth (SDD) as independent variables for estimating aquatic productivity and the degree of impairment. TSIs for each of these components are frequently averaged to produce a single TSI value associated with a trophic state classification (e.g., oligotrophic, mesotrophic, or eutrophic). The potential divergence among equations and classification systems originally developed...
Submerged Aquatic Vegetation Species and Populations Within Species Respond Differently to Environmental Stressors Common in Restorations
01. Oktober 2021
Abstract Submerged aquatic vegetation (SAV) improves environmental conditions by acting as a sediment stabilizer and nutrient retention tool; therefore, reintroduction of SAV is a common freshwater restoration goal. Initial plant establishment is often difficult in suboptimal conditions, and planting material with specific traits may increase establishment rates. Here we evaluate the variability in plant traits based on collection location. We find consistent differences in traits of plants collected from different natural water bodies, and those differences persist in...
Coping and Adaptation in Response to Environmental and Climatic Stressors in Caribbean Coastal Communities
01. Oktober 2021
Abstract Cumulative and synergistic impacts from environmental pressures, particularly in low-lying tropical coastal regions, present challenges for the governance of ecosystems, which provide natural resource-based livelihoods for communities. Here, we seek to understand the relationship between responses to the impacts of El Niño and La Niña events and the vulnerability of mangrove-dependent communities in the Caribbean region of Colombia. Using two case study sites, we show how communities are impacted by, and undertake reactive short-term responses to, El Niño and...
Small-Scale Woodlot Growers’ Interest in Participating in Bioenergy Market In Rural Ethiopia
01. Oktober 2021
Abstract Production of value-added outputs from biomass residues represents an opportunity to increase the supply of renewable energy in Ethiopia. Particularly, agroforestry could provide biomass residues for improved bioenergy products. The aim of this study was to characterize the interest of growers to provide biomass residues to a hypothetical biomass feedstock market. This study relied on a survey conducted on a sample of 240 farmers. Although the awareness of potential biomass products was generally quite low, a majority of farmers expressed interest in supplying...
Expanded Ethical Principles for Research Partnership and Transdisciplinary Natural Resource Management Science
01. Oktober 2021
Abstract Natural resource researchers have long recognized the value of working closely with the managers and communities who depend on, steward, and impact ecosystems. These partnerships take various forms, including co-production and transdisciplinary research approaches, which integrate multiple knowledges in the design and implementation of research objectives, questions, methods, and desired outputs or outcomes. These collaborations raise important methodological and ethical challenges, because partnering with non-scientists can have real-world risks for people and...
Resident Knowledge of and Engagement with Green Infrastructure in Toronto and Philadelphia
01. Oktober 2021
Abstract Green infrastructure (GI) initiatives, including programs to plant trees and install bioswales, have been adopted by a growing number of local government and non-governmental organizations. While the details of these programs vary, a common characteristic of most Canadian and US GI initiatives is a distributed approach that includes both public and private land. To date, little research has explored residents’ knowledge of GI or their engagement with related initiatives even though residents’ installation of GI is often key to creating distributed GI...
From Project Impacts to Strategic Decisions: Recurring Issues and Concerns in Wind Energy Environmental Assessments
01. Oktober 2021
Abstract Wind energy is among the fastest-growing renewable energy source. Although not as controversial as fossil fuel-based energy projects, wind energy projects can be contested. Understanding common environmental assessment issues surrounding wind energy projects is important for addressing the transaction costs for renewable energy projects. This research examined 16 environmental assessments (EAs) for wind energy projects in Western Canada to identify the recurring issues and concerns raised by government reviewers, project interveners, and other affected...
Large-scale Degradation of the Tocantins-Araguaia River Basin
01. Oktober 2021
Abstract The Tocantins-Araguaia Basin is one of the largest river systems in South America, located entirely within Brazilian territory. In the last decades, capital-concentrating activities such as agribusiness, mining, and hydropower promoted extensive changes in land cover, hydrology, and environmental conditions. These changes are jeopardizing the basin’s biodiversity and ecosystem services. Threats are escalating as poor environmental policies continue to be formulated, such as environmentally unsustainable hydropower plants, large-scale agriculture for commodity...
Identifying Priorities, Targets, and Actions for the Long-term Social and Ecological Management of Invasive Non-Native Species
29. September 2021
Abstract Formulating effective management plans for addressing the impacts of invasive non-native species (INNS) requires the definition of clear priorities and tangible targets, and the recognition of the plurality of societal values assigned to these species. These tasks require a multi-disciplinary approach and the involvement of stakeholders. Here, we describe procedures to integrate multiple sources of information to formulate management priorities, targets, and high-level actions for the management of INNS. We follow five good-practice criteria: justified...
Wealth and Education Influences on Spatial Pattern of Tree Planting in a Tropical Metropolis in Brazil
28. September 2021
Abstract Green infrastructure, and specifically urban afforestation, is one of the most important activities of city management today, because of the multitude of ecosystem services it provides. The pattern of tree planting in urban areas is related to age, ethnicity, education, and household income. Unfortunately, this issue has not been evaluated, nor has it received significant subsidized governmental actions, funding, study, or public policies in large tropical cities in developing countries. Thus, we aimed to investigate if there was a pattern of urban afforestation...

A Process-Oriented Model of Decision-Making toward Landscape-Scale Prescribed Fire Implementation in the Southern Great Plains, USA
20. September 2021
Abstract In this investigation, we developed a model of the psychological drivers of landowners’ decisions to implement prescribed fire on their properties. The Southern Great Plains in the USA evolved with fire and prescribed fire is an important management tool aimed at maintaining and enhancing ecological and economic resilience in the region. The conceptualized model is reflective of a decision-making paradigm that considers decision making to be a process inclusive of a variety of factors and their inter-relationships to arrive at judgments on whether or not to...
