AbstractThe objective of this study was to estimate the economic impact of the sugarcane aphid (SCA) outbreak in the Rio Grande Valley (RGV), Texas. Local producers were surveyed to gather detailed information about crop production and pest control practices. Collected data were used to estimate the reduction in profit associated with the SCA infestation, as well as the monetary value of the prevented loss attributed to control efforts. Sorghum industry losses were then used to assess the overall economic impact of the SCA outbreak in the RGV economy.

The aim of the study was to assess the economic impact of the Coronavirus on the production and distribution of livestock across the value chain approach in the case of Kellem Wollega Zone, Oromia National Regional State, Ethiopia, based on a total survey of 320 farmers. Descriptive statistics were used to present the effects of the pandemic on the marketing and consumption of major crop production and dairy products in the study areas. Survey result indicated that about 160 small holder farmers those involved in agriculture in the study areas were impacted by COVID-19 crises because the revenue of the farmer were close to down from 25 per cent to 50 per cent. The survey results also indicated that more than 37 per cent of the sample households in the study area affected by the COVID-19 crisis on workforce reduced consumer confidence. Lower demand in virus-affected states across the world will be transferred down the value chain, affecting demand and production levels at each stage, even in areas not directly affected by the virus. It seems that logistical issues linked to the COVID-19 crisis are creating extra costs in the coffee marketing system. Logistical and administrative issues regarding to the COVID-19 during the production time in the study areas were very low to providing service particularly input and fertilizer for the farmers on the time. Therefore, this study recommends that both fiscal and monetary policy instruments introduced by the government to fight the pandemic shall be continued, enforced and implemented in a coordinated way to support the effectiveness of interventions until the economy recovers.


ABSTRACT This study aimed at assessing the economic impact of Pusa Rudhira variety using an economic surplus approach during 2014-15 in Haryana. Primary data were collected from Panipat, Sonepat and Fatehabad districts purposively on account of a large area under vegetable cultivation and the total sample was 120 farmers. The results revealed that there was an economic surplus of 100.84 crores generated out of this technology. Of this total surplus, the share of producers’ and consumers’ gains was around 66 and 34 percent respectively. It implied that such benefits came from investment in research of this crop production technology. Financial viability analysis of returns to investment in research of developing the Pusa Rudhira variety showed that the project was economically viable since benefit-cost ratio (BCR) and internal rate of return (IRR) was 447 and 138 percent respectively. Sensitivity analysis was conducted, four scenarios were developed keeping both supply and demand elasticity at a different level. While keeping inelastic demand and supply elastic, the economic surplus was 59.4 crore.

Myanmar is the country with the highest economic vulnerability (EV) to climate change in the Southeast Asian region. The dry zone of Myanmar occupies two-thirds of the agricultural lands and it has higher temperatures than elsewhere in the country. Climate change has severe impacts on agricultural production in this region. Moreover, changes in the precipitation patterns increase the likelihood of crop failures in the short-run and production declines in the long run. Therefore, an assessment of the economic impacts of climate change on crop production in the dry zone of Myanmar is very relevant. This paper examines the interactions between agriculture and climate and assesses the economic impact of climate change while using a Ricardian model. A cross-sectional survey covering three regions in the central dry zone: (Magwe, Mandalay, and Sagaing regions) was conducted, yielding a sample of 425 farmers. A non-linear relationship between climate indicators (temperature and precipitation) and revenue of land was found. The marginal effects were calculated by selecting economic and socio-demographic variables. The estimated marginal impacts suggest that the projected changes in temperature will affect the crop productivity of the region. The results also show that the temperature and rainfall components of global warming are both important. Predictions from three global circulation models all confirm that temperature is predicted to increase in all seasons. A significant marginal impact of increasing temperature on the net revenue of farm households was observed in the region. These findings call for policy makers and development planners to articulate the necessary climate change adaptation measures and mitigation options for reducing the negative impacts of climate change. Improved management and conservation of the available water resources could generate water for irrigation purposes and the dissemination of climate smart agricultural practices could lessen the negative impacts of climate change effects on agriculture in the dry zone of Myanmar.
