RESUMO

International trade has a significant impact on global environmental quality and sustainable economic development. Global value chains (GVCs) have become a crucial component of international trade and development policy. The global production structure has become more complicated with the inclusion of domestic markets in GVC, putting significant pressure on world energy resources and environmental sustainability. Therefore, traditional trade measures no longer accurately reflect how global trade affects the energy security of developing and developed countries. Thus, this study is the first to use a panel-corrected standard error method to look at the relationship between GVC participation and energy security by using a global sample of 35 developed and 27 developing nations from 1995 to 2018. A feasible generalized least squares model was also applied to confirm the robustness of the model. Six indicators-foreign direct investment, industrialization level, capital formation, human capital index, political stability, and GVC-were used in this research to look at their impact on the four fundamental pillars of energy security (availability, applicability, sustainability, and affordability) for sustainable economic development. For developed countries, it was confirmed that there is a non-linear relationship between GVC participation and energy intensity, renewable energy consumption, and non-fossil fuel use. In the case of developing countries, the non-linear relationship in terms of all aspects of energy security was also confirmed. The findings also indicated that GVC's involvement benefits all four dimensions of energy security in both developing and developed countries once it reaches a certain threshold. Our findings further support the impacts of long-term cointegration between GVC and energy security for sustainable economic development. Therefore, the nations must promote technology transfer and capacity building within GVCs for inclusive energy security. Similarly, they may foster sustainable practices through collaborative governance for a stable global energy network by acknowledging the positive impact of income levels on energy security.

RESUMO

Using panel data from BRICS countries over the period 2000 to 2018, a multi-variate threshold model was built to investigate how global value chain (GVC) participation and information globalization affects CO2 emission. We further decompose the information globalization into two indicators, i.e., de facto measure and de jure measure. The main findings show that the estimated value of threshold is 4.02 and 1.81 for both de facto and de jur measures of information globalization. The findings suggest that information globalization rate above the threshold level negatively affects the carbon emissions. De facto and de jure measures show a strong single threshold effect when GVC participation is chosen as the major explanatory variable. Similarly, participation in GVCs has a large single threshold impact when information globalization is taken as the primary independent variable. Overall, the results show that the larger the information globalization for the countries under analysis, the modified impact of GVC participation on CO2 emission reduction is larger. The robustness test validates the stability and coherence of the study's findings. The opportunities that the information globalization along the approach to participate in GVCs presents for the accomplishment of carbon neutrality should be properly utilized by policymakers. There should be expansion the participation in GVCs with digital infrastructure and to enhance the assessment system for the use of technology spillover effects to increase environmental-friendly GVC ladder.

RESUMO

Governments around the globe are trying to find sustainable solutions for lessening pressure on natural resources and reducing carbon emissions. Daily household consumption of food, energy, and water has an impact on stocks of natural resources, environmental quality, and climate change. Households have significant potential for increasing conservation actions for efficient use of natural resources and greenhouse gas emissions. Households could contribute to a clean and healthy environment by adopting sustainable household practices through lower per capita consumption and carbon emissions. This study explored the role of different sustainable household consumption practices in promoting a clean environment as well as the factors affecting the adoption of these practices in Pakistan. Factor analysis and an ordered probit model were used to analyze the data from 1424 participants chosen through a multistage random sampling technique. The factor analysis identified 35 sustainable household practices for sustainable consumption. These 35 practices were grouped into the underlying factors of "Food" (14 items), "Energy" (12 items), and "Water" (9 items). The results from the econometric model showed a significant relationship between gender, education, residential area, family size, and income and the adoption of sustainable household consumption practices. Statistically, higher levels of reported sustainable consumption practices were apparent among females, households living in urban areas, more educated people, individuals of large family sizes, and more affluent households. Therefore, public policies for taking care of the environment need to put households at the center while at the same time promoting mass uptake of sustainable consumption practices related to food, energy, and water. In addition, the sector-specific policies also need to be augmented through focus on household-level consumption and production dynamics for achieving the UN's SDGs.

RESUMO

Livestock plays a vital role in humans' food and nutrition security under rapidly changing climatic scenarios. This study investigates the nature and factors affecting livestock farmers' choices of climate-smart livestock practices by using a multivariate probit model and then estimates the average effect of these adopted strategies on per capita daily dietary (calorie, protein, and calcium) intake among livestock herders. For this purpose, data were collected from 196 livestock farmers residing in the Punjab province of Pakistan, selected through multistage purposive and random sampling. The Simpson diversity index results revealed that farmers used diversified food in their daily diet. The results also showed that farmers consumed more protein-rich food items as compared to calorie and calcium-rich food items in their daily diet. Moreover, the average per capita calorie intake of livestock farmers was 2413.19 kcal/day. Livestock farmers adopting a higher number of climate-smart livestock practices consumed more daily per capita calories, protein, and calcium compared to those who adopted a lower number of climate-smart livestock practices on livestock farms. Moreover, climate-smart livestock practices produced more and better nutritional outcomes in combination with each other than in isolation. Livestock training was found to be positively associated with the adoption of more climate-smart practices. Therefore, livestock training is necessary to expedite the adoption of climate-smart practices and to improve the nutritional security of the farmers.

RESUMO

Climate change is a serious threat to global agriculture and the farming community is well aware of this challenge. This is the first empirical study that looks beyond the traditional studies only limited to the adoption of climate change measures by estimating the impact of adopted practices on technical efficiency and computing the actual level of fertilizer at the farm level. For this purpose, face-to-face interviews were conducted for data collection with 196 farmers selected through multiple stage simple random sampling in the wheat-maize mix cropping zone of Punjab province. The results depicted that changing fertilizer was the most commonly adopted strategy (76%) to negate the effects of climate changes on crop production. Stochastic frontier analysis results revealed that the adoption of diversification practices, soil and water conservation practices, and modern input use strategies were influential factors explaining the technical efficiency differential among different farmers. The average technical efficiency score was 0.71 in the locality implying that farmers have an opportunity to increase their farm efficiency by 29% with the present level of inputs. Moreover, adopters of modern input practices with a high index were 27% more efficient than those with a low adaptation index of these climate countering measures. The empirical results also revealed the excessive use of nitrogen fertilizer to counter the climate change impacts at the agricultural farms. This result has important policy implications for government agencies that it is not enough just to guide and motivate the farmers to adopt certain strategies to negate the effect of climate change. They should also be informed about the exact usage level of those suggested measures.

RESUMO

This study focuses on the sustainability of different land tenure farms in tea farming and explores the effect of structural and decisional variables on tea farm sustainability. For this, a total of 138 tea growers from the Rize province of Turkey were selected through a stratified sampling approach and interviewed directly. The positive and negative effects of independent variables on all dimensions of sustainability were emphasized after an extensive review of the literature. This reviewing activity also facilitated hypothesizing the possible influences of variables on overall tea sustainability. A tobit model was used to examine the influence of the structural and decisional variables on tea farm sustainability. The results described that owners were more sustainable compared with shareholders. Their economic and social sustainability levels were not significantly different from each other. However, environmental sustainability at owners' tea farms was more satisfactory than that of shareholders. Among structural variables, land slope, age of tea orchard, and farmers' age were negative influences, whereas cooperative membership and terrace status affected tea farm sustainability positively. Similarly, among decisional variables, family labor, fertilizer application methods, farmers' willingness to perform a soil test, and sale value of tea had positive influences, whereas the cost of chemical fertilizers had a negative influence on tea farm sustainability. The land tenure was found to have a significant effect on sustainability when the tea farmer was the owner of the farm. Thus, farmers should replant their orchards on time, and adopt sustainable practices such as terracing and employing environment-friendly fertilizer application methods for increasing tea sustainability in the locality.

RESUMO

INTRODUCTION: The world is facing a formidable challenge to prevent the COVID-19 global outbreak, and health care systems are under pressure globally. The governments alone cannot prevent the spread of this pandemic without creating a sensitive public opinion and cooperation. Therefore, this study analyzed the knowledge, behavior, and precautionary measures taken by the general public to protect themselves from COVID-19 pandemic. METHODOLOGY: For this purpose, snowball sampling technique was used to collect data from 401 respondents through an online survey in the Punjab province of Pakistan. A Multivariate Probit Model was used to determine the factors affecting the choice of precautionary measures to avoid COVID-19 infection. RESULTS: Majority of the respondents (58.1%) belonged to urban areas in this study. The urban respondents had higher knowledge about Coronavirus disease as compared to rural respondents. Similarly, the hygienic behavior of urban respondents was better than rural respondents. But unavailability of hygienic material (mask and hand sanitizer) was the main problem faced by the general public. Public transportation was considered the most risk-prone place to COVID-19 by the respondents. Majority of the respondents perceived medium to highest risk from COVID-19, and it was found one of the most influential factors affecting the adoption of precautionary measures along with knowledge of this pandemic. CONCLUSIONS: Government needs to start a comprehensive awareness campaign on social media along with the mainstream media create awareness about the importance of social distancing, washing hands and wearing masks among the general public to enhance knowledge and improve the behavior of the general public about COVID-19.

RESUMO

The extensive use of synthetic fertilizers is increasing continuously to meet the growing demand of food worldwide. This excessive use of fertilizer not only pose a threat to the sustainability but also cause negative externalities in form of hidden social cost to the society The present study estimated social costs and benefits associated with excessive use of chemical fertilizers at tea farms and also evaluated eco-efficiency of tea growers in Rize Province of Turkey. Data envelopment analysis (DEA) was used in this study. Tea growers are 68% eco-efficient in the locality. They can reduce their average fertilizer use from 115.45 to 66.45 kg and labor from 9.88 to 8 days per decare. The overuse of fertilizers at tea farms emits 289.3 kg/hectare of greenhouse gases. Therefore, by applying the eco-efficient fertilizer target level, 1574.48 tons of gas emissions only in Rize Province and 23,997.57 tons in whole Turkey can be reduced. The cost of 1 kg gas emissions was calculated as 0.3316 TL. The optimal level of fertilizers (social costs = social benefits) was also similar to the target level. The fertilizer use efficiency analysis showed that the tea growers cannot only reduce their fertilizer quantity by 49.03 kg/decare without compromising the crop yield, but can also contribute to the healthy environment with a low level of greenhouse gas emissions. Tea growers should replace their older tea orchards with new ones in order to achieve social and eco-efficient levels as well as to maintain viable yield level.

RESUMO

Climate change is not a myth anymore and changing with every passing year regardless of the efforts to mitigate its root causes. Livestock being a key source of employment to a large poor world population also contributes to food security and poverty eradication. With the changing climate livestock farmers are also making their farms compatible to the new natural ecosystem. Therefore, this study investigated how small livestock farmers having large ruminants inventory perceive changes in climate, which strategies they adapt and the factors influencing the adaptation of climate changes strategies in livestock. Primary data was collected from 180 small livestock farmers of Central Punjab, and multiple (step-wise) regression analysis was used to determine the factors affecting adaptation of climate change strategies. Livestock farmers are also well aware of the climate change as majority of the farmers (63.4% and 71.4%) perceived an increase in temperature and precipitation, respectively. Livestock farmers made an attempt to adopt conventional climate change strategies such as mix farming, reduction in animals, provision of more drinking water, use of tree shades, livestock diversification, use of muddy roof, and floor in order to cope with climate changes. The adoption of these measures was significantly influenced by animal inventory, climate knowledge, livestock working hours, livestock experience, distance of veterinary hospital, and livestock-related training/workshops. Government needs to increase technical and logistic capacity of veterinary doctors, and should create awareness among small livestock farmers through media.

RESUMO

ABSTRACT: Self-operated land and operated by tenure may affect the sustainability of farming in a region. This study planned to analyze how rural households switch away from tea farming even they have parental land, and how landless access the land for tea farming. For this a total of 138 tea growers were interviewed including 27 farmers who had just ownership of land and had left the tea farming. Logistic regression was applied to assess the determinants of rural household's decision to exit and enter the land market. Farmers were compared over their farm management practices and personal characteristics. The owned farmers were good in management and adoption of good practice in tea farming than those who accessed land as a shareholder and not had their own land. Rural households head as getting older, having high education and also having an off-farm occupation, having more university graduated family members, and family members having off-farm occupations are more likely to exit from farming and supply their land to rental markets. On the other side, an older and highly educated head of landless family is less likely to become a shareholder. Here also off-farm occupation has a negative and insignificant effect on the probability of landless household working as a shareholder. If the head of the landless family has a wish to become a successful farmer, then he is more likely to work as an owner. It implies that a person is less likely to work as a shareholder and more likely to get land with ownership rights not only land-using rights.


RESUMO: Propriedades auto-operados e operados pela posse podem afetar a sustentabilidade da agricultura em uma região. Este estudo planejou analisar como as famílias rurais se afastam da produção de chá, mesmo as que possuam terras parentais, e como os sem-terra acessam a terra para a produção de chá. Nesse total, 138 produtores de chá foram entrevistados, incluindo 27 agricultores que possuíam apenas a propriedade da terra e deixaram a lavoura. A regressão logística foi aplicada para avaliar os determinantes da decisão da família rural de sair e entrar no mercado de terras. Os agricultores foram comparados com suas práticas de gerenciamento agrícola e características pessoais. Os agricultores proprietários foram considerados bons em gestão e adoção de boas práticas na agricultura de chá do que aqueles que acessaram a terra como acionista e não possuíam terras próprias. Os agregados familiares rurais envelhecem, têm ensino superior e também uma ocupação fora da fazenda, tendo mais membros da família graduados na universidade e com ocupações fora da fazenda têm mais probabilidade de sair da agricultura e fornecer suas terras para os mercados de arrendamento. Por outro lado, um chefe de família sem terra, mais velho e altamente educado, tem menos chances de se tornar um acionista. Aqui também a ocupação fora da fazenda tem um efeito negativo e insignificante na probabilidade de famílias sem terra trabalharem como acionistas. Se o chefe da família sem terra deseja se tornar um agricultor bem-sucedido, é mais provável que ele trabalhe como proprietário. Isso implica que é menos provável que uma pessoa trabalhe como acionista e obtenha terras com direitos de propriedade e não apenas direitos de uso da terra.
