The paper examines the impact of financial development on agricultural productivity in South Asia using data for the period 1973–2015. The other variables included are physical capital, human capital, trade openness and income level. It is found that all variables have cross-section dependence and they are stationary at first differences. It is found that long-run cointegration holds among variables. The estimated results show that financial development has an inverted U-shaped effect on agricultural productivity, which implies that agricultural productivity first increases with the increase in financial development and then it declines when financial development further increases. Agricultural productivity increases with the increase in both physical and human capitals. Agricultural productivity also improves with trade openness and income level. The results of the robustness analysis show that terms of trade has a negative effect on agricultural productivity. Further, industrialisation has positive while carbon emission and rural labour force have negative effects on agricultural productivity in the region.<br />

Economist Stern (2016) asks now why so little is concretely done against global warming. But consider the huge countries in South Asia and their mighty neighbours. South Asia is poised to become the next set of Asian economic miracles. Yet they face a terrible threat from the environment, as global warming picks up speed together with more and more environmental degradation. Can these more than 2 billion people work and find food and water, if temperature rises more than 2-3 degrees? Can peasants work and survive? And how to generate enough electricity for housing, given increasing water shortages? Without massive financial assistance, there will occur widespread reneging on the COP21 objectives (Goal I-III). The system of UNFCCC with yearly big meetings does not offer an organization that is up to the coordination tasks involved in halting climate change—too much transaction costs. South Asia needs the promised Super Fund badly that Stern anticipated 2007.

Agribusiness plays a key role in the sustainable economic development of rural poor by fulfilling daily needs. In South Asia, all the countries have a similar pattern of societies, resources, climates, practices, and people located close to each other. Crop cultivation, dairy production, fishery, and forestry are the main agribusiness sectors for trading agricultural produce in markets. In contrast, factors (i.e., global warming due to climate change, natural calamity, environmental pollution, unsafe foodstuff, labor unavailability, marketing limitations, and financial crisis) are responsible for a serious fatal to agribusiness activities. Unless we uproot challenges, agribusiness cannot contribute effectively to the economy of developing nations in South Asia. Thus, future strategies may be standing on contemporary scientific research approaches on crop science, restoring resources, controlling food quality, introducing modern types of machinery, best marketing practices, and inclusive financing.

AbstractThis paper evaluates the impact of climate change on agricultural productivity. Cross-sectional variation in climate among Brazilian municipalities is used to estimate an equation in which geographical attributes determine agricultural productivity. The Intergovernmental Panel on Climate Change (IPCC) predictions based on atmosphere–ocean, coupled with general circulation models (for 2030–2049), are used to simulate the impacts of climate change. Our estimates suggest that global warming under the current technological standards is expected to decrease the agricultural output per hectare in Brazil by 18 per cent, with the effects on municipalities ranging from−40 to+15 per cent.

Abstract. The 2015 Paris Agreement proposed a more ambitious climate change mitigation target on limiting global warming to 1.5 ∘C instead of 2 ∘C above preindustrial levels. Scientific investigations on environmental risks associated with these warming targets are necessary to inform climate policymaking. Based on the Coupled Model Intercomparison Project phase 5 (CMIP5) climate models, we present the first risk-based assessment of changes in global drought and the impact of severe drought on populations from additional 1.5 and 2 ∘C warming conditions. Our results highlight the risk of drought on a global scale and in several hotspot regions such as the Amazon, northeastern Brazil, southern Africa and Central Europe at both 1.5 and 2 ∘C global warming relative to the historical period, showing increases in drought durations from 2.9 to 3.2 months. Correspondingly, more total and urban populations would be exposed to severe droughts globally (+132.5 ± 216.2 million and +194.5 ± 276.5 million total population and +350.2 ± 158.8 million and +410.7 ± 213.5 million urban populations in 1.5 and 2 ∘C warmer worlds) and regionally (e.g., East Africa, West Africa and South Asia). Less rural populations (−217.7 ± 79.2 million and −216.2 ± 82.4 million rural populations in 1.5 and 2 ∘C warmer worlds) would be exposed to severe drought globally under climate warming, population growth and especially the urbanization-induced population migration. By keeping global warming at 1.5 ∘C above the preindustrial levels instead of 2 ∘C, there is a decrease in drought risks (i.e., less drought duration, less drought intensity and severity but relatively more frequent drought) and the affected total, urban and rural populations would decrease globally and in most regions. While challenging for both East Africa and South Asia, the benefits of limiting warming to below 1.5 ∘C in terms of global drought risk and impact reduction are significant.
