1. Identifying resource-conscious and low-carbon agricultural development pathways through land use modelling.
PMID:日期:2024-08-01Increasing agricultural production with current resources and technology may lead to increased GHG emissions. Additionally, large population countries like India face substantial challenges in terms of food demand, agro-ecological heterogeneity, carbon footprint and depleting natural resources, thus increasing the decision complexities for policymakers and planners. We aim to examine the potential of producing more food from available agricultural land with low-carbon (reduced GHG emissions) and resource-conscious (optimal resource use) options. The current study develops multiple calorie production and emission-centric land use using a land use optimization model wherein the calorie production and emission objective, resource and emissions constraints, and food production targets interact across multiple spatial levels. The capabilities of the developed model are demonstrated with a case study in India targeting ten crops (grown over two seasons) covering three food groups (cereals, legumes, and oilseeds). Three hypothetical scenarios for each objective of maximizing calories production (, , ) and minimizing GHG emissions (, , ) are developed concerning targets of national crop production (, ), state food groups production (, ), and state crop production(, ), with different spatial levels of constraints. A maximum growth of 11% in calorie production is observed in while mitigating 2.5% emissions. Besides, the highest emission reduction of around 30% is observed in but with no change in calorie production. Emission scenarios can spare up to 14.8% land and 18.2% water, while calorie production-maximization scenarios can spare a maximum of 4.7% land and 6.5% water. The optimization-based methodology identifies the regions of altered land use by proposing appropriate crop substitution strategies, such as increasing oilseeds in Rajasthan and soybean in east Maharashtra. Many states show conservative production growth and emission reduction with state-level crop production targets (), suggesting crop redistribution within the state alone will not be sufficient unless improved technologies are introduced. The maximum growth and mitigation potential estimated in this study may be affected by climate shocks; therefore, introducing the improved technologies needs to be coupled with a crop redistribution mechanism to design climate-resilient and futuristic land use systems. The proposed land use model can be modified to incorporate climate change effects through consideration of scenarios of changed crop yields or through direct/indirect coupling with dynamic crop simulation models.

2. Land tenure, food security, gender and urbanization in Northern Ghana.
PMID:日期:2023-09-01Links between land tenure and food and nutritional insecurity are receiving increased attention. Nevertheless, urban and periurban dwellers face challenges in accessing land to produce food for subsistence and sale. An ethnographic study and food and nutrition insecurity survey were conducted between October 2013 and November 2014 in Tamale, Northern Region of Ghana, to explore the dynamic and recursive links between land access, food access and the ability to maintain resources to meet long-term needs. Results showed that infrastructural development and agriculture compete for land. The shortage of land for agricultural purposes was pronounced in urban areas (20%) than in periurban areas (1.3%) and rural areas (0%). Food insecure households were more likely to name a lack of land than anything else as the primary reason for their inability to grow crops (Fisher's exact probability = 0.040). Urban and periurban dwellers cope with the constraints posed in the communal tenure system by using strategies such as urban-periurban-rural migrant farming and buffer zone cultivation. The role of women in providing nutritious soups is especially important, and they use various mechanisms to circumvent their lack of access to land and provide food for the household. Political, economic and cultural elements thus interact to constitute the link between land and food.

3. ICT use and spatial fragmentation of activity participation in post-COVID-19 urban societies.
PMID:日期:2022-09-01With the outbreak of the COVID-19 pandemic, the use of Information and Communications Technology (ICT) came to dominate daily activities (e.g., e-working, e-shopping, and e-leisure). The intensive use of ICT might trigger higher levels of spatial fragmentation of daily activities, having significant consequences for planning purposes. This paper seeks to estimate how ICT use and habits affect the individuals' spatial fragmentation patterns in urban contexts on post-COVID-19 societies, while controlling for socioeconomic and built environment characteristics. The city of Alcalá de Henares (Madrid Metropolitan Area, Spain) serves as the case study. The research design is based on activity diaries obtained by face-to-face interviews, and Tobit and Poisson regression analyses are used to examine the relationships between spatial fragmentation measures (outcome variable) and ICT use (predictors). The results reveal that ICT might originate higher spatial fragmentation for work-related activities than for shopping-leisure purposes. For working activities, higher spatial fragmentation patterns are found among people with higher willingness to e-work and individuals who e-work at least once a month, but rather dependent on the occupation type. Regarding shopping and leisure activities, higher spatial fragmentation patterns are noted with car owners and more frequent consumers of online entertainment. The study provides insight into how ICT use is transforming spaces traditionally adapted for a single purpose into multifunctional spaces as well as the spatial effect of this phenomenon.

4. Impact of COVID-19 in the forestry sector: A case of lowland region of Nepal.
4. 新冠肺炎对林业部门的影响：尼泊尔低地地区的一个案例PMID:日期:2022-09-01All walks of life have been affected by COVID-19 but smallholders from developing countries have been impacted more than others as they are heavily reliant on forest and agriculture for their livelihoods and have limited capacity to deal with COVID-19. Scholars are heavily engaged in assessing the impacts of COVID-19 on health and wellbeing, gender, food production and supply, stock market and the overall economy but not on the forestry sector. Using questionnaire surveys and key informant interviews-informed by grey literature and published articles- representing Division Forest Offices, Provincial Forest Directorates, and the Ministry of Forests and Environment in Nepal, this study assessed the impact of COVID-19 on the forestry sector of Nepal. Our analysis suggests that: (1) nature-based tourism is more severely affected than other sectors; (2) private, religious and leasehold forests faced minimal impacts of COVID-19 than that of community and government-managed forests; (3) wild boar (Sus scrofa), different species of deer, and birds have been more impacted than other wild animals; (4) the price of the timber has increased significantly whereas the price of non-timber forests products (NTFPs) has decreased; and (5) illegal logging and poaching have increased but the incidence of forest encroachment has been reduced. Our study further reveals that agroforestry practices in home gardens, borrowing money from neighbors/banks/landlords and liquidating livestock remained key alternatives for smallholders during COVID-19. Many studies reported that reverse migration could create chaos in Nepal, but our study suggests that it may enhance rural innovation and productivity, as returnees may use their acquired knowledge and skills to develop new opportunities. As COVID-19 has created a war-like situation worldwide, Nepal should come up with a forward-looking fiscal response with alternative income generation packages to local living to counter the impacts of COVID-19 on the forestry sector. One of the options could be implementing similar programs to that of India's US$ 800 Compensatory Afforestation Program and Pakistan's 10 Billion Tree Tsunami Program, which will create a win-win situation, i.e., generate employment for reverse migrants and promotes forest restoration.

5. Housing market volatility under COVID-19: Diverging response of demand in luxury and low-end housing markets.
PMID:日期:2022-08-01The ongoing pandemic has led to substantial volatility in residential housing markets. However, relatively little is known about whether the volatility is dominated by housing demand or supply, and how different priced markets contribute to the volatility. This article first examines the temporal effect of COVID-19 on house prices, housing demand, and supply in Los Angeles, and second explores the effect heterogeneity in luxury and low-end housing markets within the city. For identification, the article employs a revised difference-in-differences (DID) method that controls more rigorously for unobservables and improves on the traditional DID with smaller prior trends. Using individual level data, the result first shows that, in response to the outbreak, house prices, demand, and supply all decreased in March to May 2020 and increased in July and August 2020, with demand dominating the process. Second, the heterogeneity exploration identifies diverging COVID-19 impacts in higher- and lower- priced markets. Particularly, the decline in overall price and demand before June originates mainly from the lower-priced market while the higher-priced one experienced limited changes in demand. After July, higher-priced markets led housing market's surge in price, demand, and supply, whereas the lower-priced market has not fully recovered from decreases in house prices and housing demand. Finally, a larger price decline in lower-priced markets is found to be associated with higher service shares and lower homeownership rates. The results not only facilitate market participants in their decision making but also aid local governments in formulating policies and allocating subsidies to mitigate the effects of the outbreak.

6. Relationships between urban form and air quality: A reconsideration based on evidence from China's five urban agglomerations during the COVID-19 pandemic.
PMID:日期:2022-07-01The outbreak of Coronavirus disease 2019 (COVID-19) led to the widespread stagnation of urban activities, resulting in a significant reduction in industrial pollution and traffic pollution. This affected how urban form influences air quality. This study reconsiders the influence of urban form on air quality in five urban agglomerations in China during the pandemic period. The random forest algorithm was used to quantitate the urban form-air quality relationship. The urban form was described by urban size, shape, fragmentation, compactness, and sprawl. Air quality was evaluated by the Air Quality Index (AQI) and the concentration of six pollutants (CO, O, NO, PM, PM, SO). The results showed that urban fragmentation is the most important factor affecting air quality and the concentration of the six pollutants. Additionally, the relationship between urban form and air quality varies in different urban agglomerations. By analyzing the extremely important indicators affecting air pollution, the urban form-air quality relationship in Beijing-Tianjin-Hebei is rather complex. In the Chengdu-Chongqing and the Pearl River Delta, urban sprawl and urban compactness are extremely important indicators for some air pollutants, respectively. Furthermore, urban shape ranks first for some air pollutants both in the Triangle of Central China and the Yangtze River Delta. Based on the robustness test, the performance of the random forest model is better than that of the multiple linear regression (MLR) model and the extreme gradient boosting (XGBoost) model.

7. How much is policy driving the adoption of cover crops? Evidence from four EU regions.
PMID:日期:2022-05-01EU agriculture is facing increasing expectations and pressure from society and policymakers to support environmental protection and climate change mitigation. Catch and cover crops (CCC) are an underused farming practice that can potentially contribute towards these goals. Previous research is sparse and has yielded few relevant insights into CCC adoption behaviour by farmers. In this study we analyse a dataset from farm surveys in four EU regions to better understand the role of policy and non-policy factors in CCC adoption. Our data suggests that adoption rates vary widely between regions, while farm adoption intensities are low. We find that policy is by far the strongest determinant of adoption rates and adoption intensities. CCC adoption patterns have been shaped mainly by the Nitrates Directive and the Common Agricultural Policy's greening requirements. Agronomic motives are a third but much weaker impetus for adoption. Environmental and climate change considerations do not play a significant role in farmers' adoption decisions. Most non-adopters would likely become adopters if stronger policy obligations or additional subsidies were implemented. Non-adopters' responsiveness to subsidies and willingness to accept is highly varied but only weakly predictable from easily observed farm characteristics.

8. How do single-family homeowners value residential and commercial density? It depends.
PMID:日期:2022-02-01This paper develops estimates of the relationship between local density and single-family home values across five U.S. metropolitan areas using 2017 transactions in Chicago, Los Angeles, Minneapolis, Philadelphia, Seattle. Proposals to build new commercial and residential development projects that would increase local density commonly face opposition from local homeowners. Academic literature links the response from homeowners to concerns that higher density is associated with lower property values but there is limited empirical evidence establishing this relationship at the local level. We find a positive and significant relationship between density and house value in the core area of the five metropolitan regions we analyze. For outlying areas, the estimates are smaller and even negative in several cases. We instrument density based on topographic and soil characteristics and find similar results. These findings point to the need for a more nuanced discussion of the relationship between local density and housing values.

9. The impact of the COVID-19 pandemic on the importance of urban green spaces to the public.
PMID:日期:2022-02-01Green spaces provide people with countless intangible benefits, particularly important during crises. Restrictions imposed in many countries due to the COVID-19 pandemic forced people to maintain social distance, limit travels, and even refrain from visiting green spaces and stay at home at a certain point. The survey in one of the largest cities in Poland, Kraków, was intended to help understand the impact of the pandemic on the importance of urban green spaces to the public. The study focused on the first three stages of the pandemic in Poland, from March to November 2020. Nine weeks of the survey yielded over 1250 responses. Responses to spatial questions were analysed with GIS tools and geoprocessing algorithms. The number of visitors to green spaces during the pandemic fell to 78.9% of the population, which is down 13.1% compared to before the pandemic. At the same time, the percentage of people refraining from the visits fell with each phase of the crisis. According to the study, residents believed green spaces to be important for their mental and physical health. Over 75% of the participants considered visits to green spaces as having a very big or big impact on stress level reduction. The work provides empirical proof of the importance of green spaces to residents, particularly during a crisis. The results can affect urban spatial policies and management of green spaces and can potentially be applied in other cities.

10. Pandemic resilient cities: Possibilities of repairing Polish towns and cities during COVID-19 pandemic.
PMID:日期:2022-02-01Cities, due to population density and the complexity of human interactions, experience specific problems arising from their functioning in the era of the Covid-19 pandemic. Many scientists who publish their findings in contemporary literature agree on the need to shape pandemic resilient cities by making changes to the functional-spatial structure and preparing cities for rapid revitalization [regeneration] in the post-pandemic period. The main objective of the research is to identify the most important problems regarding service infrastructure deficiencies in the nine medium-sized Polish cities selected for research located in the Warsaw agglomeration, which are well connected with Warsaw. The research was based on: analysis of selected GIS spatial data, demographic data from the Polish Central Statistical Office, surveys among residents, on their needs during pandemic constraints. The focus was on three important aspects of development in the era of the pandemic: access to first-need services, access to greenery and active recreation areas, accessibility and transport efficiency problems. The research revealed changes in the way people travel and do their essential shopping, inadequate cycling infrastructure and problems with the availability of essential services close to where they live. The research programme varies, although the diagnosis and the possibility of transforming the functional-spatial structure of the cities studied as typical medium-sized cities in the impact zone of a large centre dominate. The conclusions provide examples of proposals for tactical urbanism planning solutions that could rapidly improve the quality of residence in a low-budget way. Finally, the proposals and guidelines for creating sustainable pandemic resilient cities are described. The article investigates the aspect of urban resilience related to transport, services, relaxation, while using the method of tactical urbanism as a remedy for cities' pandemic problems.
