<p>This research explores landowner preferences for various land use options suitable for Māori land in Te Tairāwhiti, on the East Coast of the North Island of Aotearoa-New Zealand (henceforth Aotearoa). A particular emphasis is placed on the applicability and feasibility of native forest carbon farming within the New Zealand Emissions Trading Scheme (NZ ETS) and opportunities, barriers and risks associated with this land use. Alongside this focus, is a wider investigation into the socio-cultural, environmental and economic co-benefits Māori landowners associate with traditional and emerging land uses in Te Tairāwhiti. This study uses a transformative research approach that is rooted in the spirit of kaupapa Māori research.  Some 90 percent of Māori land in Te Tairāwhiti has severe limitations which restrict land use options to plantation forestry or pastoral farming for most landowners. A response to these limitations, and a land development option favoured by government agencies, and the academy, is for ‘unproductive’ Māori land to be retired into permanent native forest carbon sinks – a solution frequently proffered as a positive means to address national climate change commitments and local environmental and socioeconomic issues. Whilst these objectives, and the land use preferences of Māori seemingly converge, the wider history of land loss and alienation influences perceptions of fairness and equity for Māori landowners who may feel pressured by the lack of attractive land use options to establish permanent carbon sinks, which can effectively constrain land use options for future generations.  Through case study analysis of a Māori sheep and beef farming incorporation participating in the NZ ETS, this study suggests an economic case for carbon farming in Te Tairāwhiti. However, institutional and socio-cultural barriers hinder the participation of Māori landowners in the NZ ETS. The second focus of this thesis has been an investigation into how native forest carbon farming is viewed when compared to other novel and existing land uses suitable for Māori land in the Waiapu catchment (a highly erodible catchment in Te Tairāwhiti). Interviews with key informants were employed to curate a set of land use options for Māori landowners to appraise, using multi-criteria analysis, at two wānanga. Four land use models were created for appraisal by 16 Māori landowner participants. The strength of association between a co-benefit and a land use was collectively deliberated upon in each of these models, and ratings were assigned to reflect this association. These ratings have aided in assessing the wider value of land uses for Māori in the region.   The results from this research indicate an overwhelming preference for native forests when compared to other suitable land uses. Native forests are most closely associated with environmental co-benefits (erosion control, water quality, biodiversity and withstanding and limiting climate change) and social and cultural co-benefits (skills development, employment, reconnecting with the land, and self-determination/autonomy). The strong performance of native forestry stands in stark contrast with other land uses under consideration such as exotic forestry (Pinus radiata within the study scenario) and sheep and beef farming which occupy the majority of ‘productive’ land in Te Tairāwhiti. Exotic forestry and sheep and beef farming are associated with few benefits beyond employment and skills development. There is also a clear perception in the quantitative and qualitative data that these uses disconnect Māori landowners from their land and reduce the ability of communities to be self-reliant.   Interestingly, other novel land uses under consideration such as perennial horticulture (including blueberries, macadamia nuts and apples), medicinal cannabis and hemp, and hunting and tourism were also valued more than exotic forestry and sheep and beef farming. These results indicate that existing land uses, sometimes implemented without express input from local communities, are now the least preferred land uses. In addition, novel and untested land uses such as medicinal cannabis and hemp, which do not exist at any scale in the region, are preferred over existing uses - even when there is scant evidence of success at any scale.   These results push back at the prevailing Pākehā dominated orthodoxy, which has existed from the early days of colonisation and holds that monoculture land uses, for profit above all else, are best suited to the land and the people. It is clear, from this study, that Māori landowners wish to move back to a vibrant multi-faceted land use regime – exemplified by diversity over homogeneity – that characterised the pre-colonisation Māori economy. This research accordingly introduces and explores a value articulating process that increases understanding of the aspirations and values of Māori landowners, and can assist Māori in progressing their land use futures.</p>

We analyzed the agricultural land-use changes in the coastal areas of Tien Hai district, Thai Binh province, in 2005, 2010, 2015, and 2020, using Landsat 5 and Landsat 8 data. We used the object-oriented classification method with the maximum likelihood algorithm to classify six types of land uses. The series of land-use maps we produced had an overall accuracy of more than 80%. We then conducted a spatial analysis of the 5-year land-use change using ArcGIS software. In addition, we surveyed 150 farm households using a structured questionnaire regarding the impacts of climate change on agricultural productivity and land uses, as well as farmers’ adaptation and responses. The results showed that from 2005 to 2020, cropland decreased, while aquaculture land and forest land increased. We observed that the most remarkable decreases were in the area of rice (485.58 ha), the area of perennial crops (109.7 ha), and the area of non-agricultural land (747.35 ha). The area of land used for aquaculture and forest increased by 566.88 ha and 772.60 ha, respectively. We found that the manifestations of climate change, such as extreme weather events, saltwater intrusion, drought, and floods, have had a profound impact on agricultural production and land uses in the district, especially for annual crops and aquaculture. The results provide useful information for state authorities to design land-management strategies and solutions that are economic and effective in adapting to climate change.

Abstract The rapid conversion of native forests to farmland in Ethiopia, the cradle of biodiversity, threatens the diversity of the arbuscular mycorrhizal fungi (AMF) pivotal to plant nutrition and carbon sequestration. This study aimed to investigate the impact of this land-use change on the AMF species composition and diversity in southern Ethiopia. Soil samples were collected from nine plots in each of three land-use types: native forest, agroforestry, and khat monocropping. The plots of the three land-use types were located adjacent to each other for each of the nine replicates. Three 10 × 10m subplots per plot were sampled. AMF spores were extracted from the soil samples, spore densities were determined, and species composition and diversity were evaluated through morphological analysis. Both spore density and species richness were statistically significantly higher in the native forest than in the agroforestry plots with no clear difference to khat, whereas the true diversity (exponential of Shannon–Wiener diversity index) did not differ among the three land-use types due to high evenness among the species in agroforestry. In total, 37 AMF morphotypes belonging to 12 genera in Glomeromycota were found, dominated by members of the genera Acaulospora and Glomus. The highest isolation frequency index (78%) was recorded for Acaulospora koskei from native forest. Consequently, the agroforestry system did not appear to aid in preserving the AMF species richness of native forests relative to perennial monocropping, such as khat cultivation. In contrast, the native forest areas can serve as in situ genetic reserves of mycorrhizal symbionts adapted to the local vegetative, edaphic, and microbial conditions.

Sea-level rise increasingly affects low-lying and exposed coastal communities due to climate change. These communities rely upon the delivery of stormwater and wastewater services which are often co-located underground in coastal areas. Due to sea-level rise and associated compounding climate-related hazards, managing these networks will progressively challenge local governments as climate change advances. Thus, responsible agencies must reconcile maintaining Levels of Service as the impacts of climate change worsen over the coming decades and beyond. A critical question is whether such networks can continue to be adapted/protected over time to retain Levels of Service, or whether eventual retreat may be the only viable adaptation option? If so, at what performance threshold? In this paper, we explore these questions for stormwater and wastewater, using a dynamic adaptive pathway planning (DAPP) approach designed to address thresholds and increasing risk over time. Involving key local stakeholders, we here use DAPP to identify thresholds for stormwater and wastewater services and retreat options, and for developing a comprehensive and area-specific retreat strategy comprising pathway portfolios, retreat phases, potential land use changes, and for exploring pathway conflicts and synergies. The result is a prototype for an area near Wellington, New Zealand, where a managed retreat of water infrastructure is being considered at some future juncture. Dynamic adaptive strategies for managed retreats can help to reduce future disruption from coastal flooding, signal land use changes early, inform maintenance, and allow for gradual budget adjustments by the agencies that can manage expenditure over time. We present this stepwise process in a pathway form that can be communicated spatially and visually, thereby making a retreat a more manageable, sequenced, adaptation option for water agencies, and the communities they serve.

Abstract. We adapt and integrate the Biome-BGC and Land Use in Rural New Zealand models to simulate pastoral agriculture and to make land-use change, intensification of agricultural activity and climate change scenario projections of New Zealand's pasture production at time slices centred on 2020, 2050 and 2100, with comparison to a present-day baseline. Biome-BGC model parameters are optimised for pasture production in both dairy and sheep/beef farm systems, representing a new application of the Biome-BGC model. Results show up to a 10% increase in New Zealand's national pasture production in 2020 under intensification and a 1–2% increase by 2050 from economic factors driving land-use change. Climate change scenarios using statistically downscaled global climate models (GCMs) from the IPCC Fourth Assessment Report also show national increases of 1–2% in 2050, with significant regional variations. Projected out to 2100, however, these scenarios are more sensitive to the type of pasture system and the severity of warming: dairy systems show an increase in production of 4% under mild change but a decline of 1% under a more extreme case, whereas sheep/beef production declines in both cases by 3 and 13%, respectively. Our results suggest that high-fertility systems such as dairying could be more resilient under future change, with dairy production increasing or only slightly declining in all of our scenarios. These are the first national-scale estimates using a model to evaluate the joint effects of climate change, CO2 fertilisation and N-cycle feedbacks on New Zealand's unique pastoral production systems that dominate the nation's agriculture and economy. Model results emphasise that CO2 fertilisation and N-cycle feedback effects are responsible for meaningful differences in agricultural systems. More broadly, we demonstrate that our model output enables analysis of decoupled land-use change scenarios: the Biome-BGC data products at a national or regional level can be re-sampled quickly and cost-effectively for specific land-use change scenarios and future projections.

The high-country and dryland zone of the South Island of New Zealand includes the Southern Alpsand eastern mountains and basins. Formed by post-Pliocene tectonic, glacial and alluvial processes, theseareas contain a range of landforms across extreme climatic gradients. Diverse habitats support plantsand animals which have a distinctive and long natural history. New Zealand’s short (c. 700 years) historyof human land use has been highly disruptive for indigenous biodiversity. We have misunderstood theeco-evolutionary vulnerabilities of the native biota, the extent of environmental limits, and the impacts ofintroduced weeds and pests. Recent large-scale capture of water and addition of nutrients for agriculture areexcluding indigenous biodiversity in many ecosystems. Predicted climate change and competition for waterresources will exacerbate agricultural impacts, but the remaining indigenous biodiversity can be resilient ifrepresentative areas are protected.

We adapt and integrate the Biome-BGC and Land Use in Rural New Zealand (LURNZ) models to simulate pastoral agriculture and to make land-use change, intensification and climate change scenario projections of New Zealand's pasture production at time slices centred on 2020, 2050 and 2100, with comparison to a present-day baseline. Biome-BGC model parameters are optimised for pasture production in both dairy and sheep/beef farm systems, representing a new application of the Biome-BGC model. Results show up to a 10% increase in New Zealand's national pasture production in 2020 under intensification and a 1–2% increase by 2050 from economic factors driving land-use change. Climate change scenarios using statistically downscaled global climate models (GCMs) from the IPCC Fourth Assessment Report (AR4) also show national increases of 1–2% in 2050, with significant regional variations. Projected out to 2100, however, these scenarios are more sensitive to the type of pasture system and the severity of warming: dairy systems show an increase in production of 4% under mild change but a decline of 1% under a more extreme case, whereas sheep/beef production declines in both cases by 3% and 13%, respectively. Our results suggest that high-fertility systems such as dairying could be more resilient under future change, with dairy production increasing or only slightly declining in all of our scenarios. These are the first national-scale estimates using a model to evaluate the joint effects of climate change, CO2 fertilisation and N-cycle feedbacks on New Zealand's unique pastoral production systems that dominate the nation's agriculture and economy. Model results emphasize that CO2 fertilisation and N cycle feedback effects are responsible for meaningful differences in agricultural systems. More broadly, we demonstrate that our model output enables analysis of Decoupled Land-Use Change Scenarios (DLUCS): the Biome-BGC data products at a national or regional level can be re-sampled quickly and cost-effectively for specific land-use change scenarios and future projections.

Abstract: The objective of this work was to evaluate the soil macrofauna and the bioindicator taxonomic groups associated with different land uses in the Colombian Amazon. Twelve agroforestry arrangements were studied and compared with to the native forest and pasture. For each land use, six monoliths were randomly selected and divided into four layers (litter, and 0-10, 10-20, and 20-30 cm soil depths). The variables considered in the analysis of land use effects were: individuals per square meter, order richness, Shannon’s diversity index, and Pielou’s evenness index. The greatest values for soil macrofauna density and diversity occurred in the forest, in contrast with the pasture. The principal component analysis distinguished land use according to macrofauna diversity, separating the native forest from the other land uses. The cluster analysis indicated the potential of some agroforestry systems to conserve the values of soil macrofauna density and diversity similar to those of the forest. According to the analysis of indicator value, five taxonomic groups (Diplura, Pseudoscorpionida, Araneae, Chilopoda, and Gastropoda), identified as bioindicators, are associated with preserved sites because of the sensitivity of their populations.

Abstract Soil health conceptualized as a measurable ecosystem property provides a powerful tool for monitoring progress in restoration projects or implementation of best management practices to promote sustainable agroecosystems. We surveyed soils collected from a range of land uses (i.e., protected native and non-native forest, managed pasture, unmanaged previously intensive agricultural lands, organic cropland, and conventional cropland) across a range of soil orders (Oxisol, Mollisol, Andisol, Inceptisol, and Vertisol) on three Hawaiian Islands. Forty-six metrics associated with soil health and encompassing biological, chemical, and physical properties were measured. In this multivariate survey, the most distinct group was the unmanaged, previously intensive agriculture lands, which was significantly different from all other land uses regardless of mineralogy. Importantly, the soil health of well-managed pastures in Hawaiʻi was not different from protected forests, suggesting that well-managed grazing lands may be as healthy and resilient as protected forests. A suite of 11 readily measured parameters emerged out of a first-principle approach to determining a holistic indication of soil health across a range of soils and systems in Hawaiʻi encompassing much of the diversity in the tropics and subtropics. Every land use may improve its soil health status within a reasonable range of expectations for a soil’s land use history, current land use, and mineralogy. Key drivers of the measures for soil health, including intensive land use history, current land use practices, and mineralogy, must be interwoven into the soil health index, which should set minimum and maximum benchmarks and weight parameters according to equitable standards.

Native forests have been replaced by forestry plantations worldwide, impacting biodiversity. However, the effect of this anthropogenic land-use change on parasitism is poorly understood. One of the most important land-use change in Chile is the replacement of native forests by Monterey pine (Pinus radiata) plantations. In this study, we analyzed the parasitism (presence and prevalence) of intestinal helminths from fecal samples of wild rodents in three habitat types: native forests and adult and young pine plantations in central Chile. Small mammals were sampled seasonally for two years, and a total of 1091 fecal samples from seven small mammal species were analyzed using coprological analysis. We found several helminth families and genera, some of them potentially zoonotic. In addition, new rodent–parasite associations were reported for the first time. The overall helminth prevalence was 16.95%, and an effect of habitat type on prevalence was not observed. Other factors were more relevant for prevalence such rodent species for Hymenolepis sp. and season for Physaloptera sp. Our findings indicate that pine plantations do not increase helminth prevalence in rodents compared to native forests.
