RESUMO

The Global Value Chain (GVC) is an essential aspect of sustainable economic growth and environmental quality in countries that participate in it. Therefore, comprehending the relationship between GVC and economic growth and carbon emissions is critical to achieving global climate neutrality targets. However, there is a paucity of knowledge regarding the impacts of disaggregated levels of GVC on economic growth and carbon emissions in countries with different income levels. In this study, we utilized the SYS-GMM model to explore the relationships between backward and forward GVCs and the economic growth and carbon emissions of 42 lower-middle, 36 middle-upper, and 48 high-income countries using data from 1995 to 2018. Our key findings suggest that forward GVC significantly increases economic growth and reduces CO2 emissions. Conversely, backward GVC reduces the economic growth and CO2 emissions of high-income countries. We also found that upper-middle-income economies can enhance their economic growth and reduce CO2 emissions by increasing their backward GVC. In contrast, lower-middle-income economies can increase their economic growth by participating in both forward and backward GVCs. However, higher levels of participation in both GVC components result in increased CO2 emissions. Our findings emphasize the importance of considering income levels when analysing the impact of GVC participation on economic growth and environmental sustainability. Overall, the relationship between economic growth and CO2 emissions with backward and forward GVCs varies significantly across country categories.

RESUMO

The acquisition of agricultural land is a crucial aspect of survival for numerous rural communities, serving as a fundamental tool for combating poverty and food insecurity and promoting equitable sustainable economic progress. The expropriation of land offers a promising prospect for remedying past inequities and promoting both economic progress and food sufficiency. Limited research has examined the association between land expropriation and food security, livelihood shocks, and the well-being of rural households worldwide. Therefore, this research explores the implications of land expropriation on food security, livelihood shocks, and well-being of land lost rural communities. The data were collected from 384 farmers selected through stratified sampling techniques using face-to-face surveys in rural China. The data were analyzed using descriptive and logit regression models. The descriptive findings showed that land expropriation has detrimental effects on the livelihood, food security, and well-being of the farmers. Furthermore, these impacts are more harmful among land-expropriated households with a lower educational level, a large family size, and women farmers in less developed rural communities. The econometric results evinced that gender, age, education level, marital status, family size, and negative changes in income all significantly affect the impact of land expropriation on the food security of farmers. Similarly, the findings revealed that farmers with lower education levels were more likely to be affected by land loss as compared to farmers with medium and high education levels. Farmers with complete land loss were 1.70 times more likely to suffer livelihood shocks than those with partial land loss. The results also evinced that the well-being of all farmers was not affected equally, and some farmers' well-being was affected more than others due to various socioeconomic backgrounds. Therefore, this study suggests the implementation of public policies that provide support to farmers who have been marginalized due to land acquisition.

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

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

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.
