Agriculture and Food in the 21 st Century

Economic, Environmental and Social Challenges- Festschrift on the Occasion of Prof. Dr. Dr. h.c. P. Michael Schmitz 65 th Birthday

Edited By Monika Hartmann and Joachim Hesse

This Festschrift in honour of Professor Dr. Dr. h.c. P. Michael Schmitz covers theoretical as well as empirical works on challenges prevailing in the food and agricultural sector. Discussions of conflicts between social and ecological requests of citizens and market outcomes are provided. The contributors discuss options of policy interventions as well as their limitations. Empirical facts that can contribute to a more evidence based policy formation are also presented. The book itself consists of two parts: «agri-food markets and policies» and «agriculture, trade and development». Topics covered are moral, markets and policies, farm animal welfare, fat taxes, agricultural derivatives markets, future food value chains, free trade agreements, food security, food waste and climate change.

Climate Change Impacts on Agriculture and the Relevance of Adaptation: The Case of Pakistan: Mirza Nomman Ahmed

Extract

Mirza Nomman AHMED

Abstract

This study uses the ricardian climate change valuation technique to estimate the economic impacts of climate change on agriculture in Pakistan. Existing studies of climate change impacts for the country do not consider the full set of farmer adaptations and thus tend to overestimate climate change induced losses. This study contributes to the literature by addressing this short-coming and additionally providing an analysis of spatial effects across Agro-Ecological Zones, provinces and farm-types using a multi-seasonal approach. Departing from an intelligent farmer’s scenario, where adaptation has ever since taken place, a hedonic analysis of farmland pricing, with climate as one determinant, is carried out. To assess the future impacts, a response function is estimated and simulations are run in a steady-state setting using Global Circulation Model scenarios. Based on the possession of agricultural land 22240 owner operated farms are selected and aggregated into 110 districts. The results confirm a non-linear relationship between climate and agricultural practice. Rainfed farms are found to be more vulnerable, whereas additional irrigation seems to be an option for farmers. All Agro-Ecological-Zones and Provinces suffer from further warming in the summer season, whereas benefits are revealed for the winter season. Those zones most severely hit, also have the lowest land values per hectare, precisely under 500$. When warming is simulated further, interesting results are revealed. Winter season benefits by 2090 over-compensate summer season losses, however not in the dryer parts of the country. In general, farmers in Pakistan are...
