Economic impacts of climate change on two Mexican coastal fisheries: Implications to food security

Aguilar Ibarra, Alonso; Sanchez Vargas, Armando; … - Institut für Weltwirtschaft (IfW) - 2012

This paper has a two-fold objective. First, to estimate the changes in landings value by 2030 of two Mexican coastal fisheries: shrimp and sardines as a consequence of climate change. And second, to discuss the implications for food security of such impacts. We estimated output equations using a...

Chinese food security and climate change: Agriculture futures

Ye, Liming; Tang, Huajun; Wu, Wenbin; Yang, Peng; … - Institut für Weltwirtschaft (IfW) - 2013

Food security in China affects the livelihood and well-being of one-fifth of the world population. Climate change is now affecting agriculture and food production in every country of the world. Here the authors present the IMPACT model results on yield, production, and net trade of major crops...

US food security and climate change: Agricultural futures

Takle, Eugene S.; Gustafson, David; Beachy, Roger; … - Institut für Weltwirtschaft (IfW) - 2013

Agreement is developing among agricultural scientists on the emerging inability of agriculture to meet growing global food demands. The lack of additional arable land and availability of freshwater have long been constraints on agriculture. However, the increased frequency of extreme and...

Impact of climate variation on agricultural productivity and food security in rural India

Kumar, Ajay; Sharma, Pritee - Institut für Weltwirtschaft (IfW) - 2013

This research paper analyzes the impact of climate change on agricultural productivity in quantity terms, value of production in monetary terms and food security in India. The study undertook state wise analysis based on secondary data for the duration of 1980 to 2009. Climate variation affects...

Russia's food security and climate change: Looking into the future

Kiselev, Sergey; Romashkin, Roman; Nelson, Gerald C.; … - Institut für Weltwirtschaft (IfW) - 2013

Global climate change presents long-term risks to agriculture. In general, global climate change is expected to positively affect Russian agriculture. In high and middle latitudes, global warming would expand the growing season. Acreages of agricultural crops may expand toward the north,...

South African food security and climate change: Agriculture futures

Dube, Sikhalazo; Scholes, Robert J.; Nelson, Gerald C.; … - Institut für Weltwirtschaft (IfW) - 2013

The projected changes in planted area, yield per area, net exports/imports and priced for five major agricultural crops in South Africa were simulated using the projections of four Global Circulation Models (GCMs) under three socio-economic scenarios. The GCM runs were those undertaken for the...

Discounting for Climate Change

Anthoff, David; Tol, Richard S. J.; Yohe, Gary W. - Institut für Weltwirtschaft (IfW) - 2009

It is well-known that the discount rate is crucially important for estimating the social cost of carbon, a standard indicator for the seriousness of climate change and desirable level of climate policy. The Ramsey equation for the discount rate has three components: the pure rate of time...

Additive Damages, Fat-Tailed Climate Dynamics, and Uncertain Discounting

Weitzman, Martin L. - Institut für Weltwirtschaft (IfW) - 2009

This paper in applied theory argues that there is a loose chain of reasoning connecting the following three basic links in the economics of climate change: 1) additive damages may be more appropriate for analyzing the impacts of global warming than multiplicative damages; 2) an uncertain...

The Social Cost of Carbon: Trends, Outliers and Catastrophes

Tol, Richard S. J. - Institut für Weltwirtschaft (IfW) - 2007

211 estimates of the social cost of carbon are included in a meta-analysis. The results confirm that a lower discount rate implies a higher estimate; and that higher estimates are found in the gray literature. It is also found that there is a downward trend in the economic impact estimates of the...
