Impacto económico del cambio climático en cultivo de quinua (chenopodium quinoa willd) orgánica en la Región del Altiplano: un enfoque Ricardiano

The climate crisis is affecting the production yield of rice, wheat, corn, coffee, beans and other food crops in the country and internationally. The objective of the research was to quantify the impact of climate change on the net income of organic quinoa producers under dry farming conditions in the Altiplano region. Using the Ricardian approach, the impact of climatic variables (temperature and precipitation) on the yield of organic quinoa was estimated in the districts of Cabana, Capachica and Ilave in the Altiplano region, and with primary data collected through a survey to A sample of 237 farmers estimated the value of land productivity. The climatic variables were provided by the National Service of Meteorology and Hydrology of Puno. The results reveal an average production of 1,497 kilos per hectare, obtaining a net income of 14,969 soles per hectare, for a market price of 9.60 soles per kilo. The adaptability of the quinoa producer to climate change was relevant to improve the productivity of the crop. In conclusion, the impact of the agroclimatic variables on the productivity-economic income of organic quinoa producers was marginal in the 2015-2016 agricultural season in the Puno Region.

Sismondi’s Price Theory: From a Liberating to a Despotic Market

This article examines the evolution of Sismondi’s price theory as well as his concept of market from 1803 to 1838. Sismondi’s early 1803 price theory in terms of supply and demand is first examined and contrasted with that of Smith in the Wealth of Nations. The progressive alterations brought to this initial formulation are discussed with the help of the relevant chapters from Nouveaux Principes ([1819] 1827) and from Études (1836–1838). In price theory terms, throughout the years Sismondi grew more and more skeptical about the process through which these prices would come about. Connecting this analytical issue with his concept of republican justice, he comes to the conclusion that a market economy characterized by unlimited competition will never lead to a socially desirable solution: such an order is neither efficient, nor natural or spontaneous and political economy is not morally neutral. In short, for Sismondi, the market never stood alone while, for him, the Ricardian approach gave nearly exclusive pride of place to market in the pursuit of wealth and happiness.

IMPACT OF CLIMATE CHANGE ON THE NET REVENUE OF MAJOR CROP GROWING FARMERS IN PAKISTAN: A RICARDIAN APPROACH

Climate change has severely affected the crops’ productivity during the last few decades across the agrarian economies of the world, thereby resulting in a considerable loss per farmer in the yearly net revenue. Pakistan’s agriculture is sensitive to warming and it experienced an adverse effect in the net farm revenue (NFR). This study primarily predicts the adverse climate effects and estimates the NFR of the farmers of five major crops (wheat, rice, cotton, sugarcane and maize) in two different seasons, winter (Rabbi) and summer (Kharif), in Pakistan. This study is based upon the secondary cross-sectional data [Household Integrated Economic Survey of Pakistan (HIES), 2015–2016] along with the time series data regarding climatic variables from 1981 to 2016. A well-established Ricardian approach has been employed to test the association between net revenue of the farmer and climatic variability. Results of overall study conclude that increases in average summer (winter) temperature and average winter (summer) rainfall have adverse (favorable) impacts on all of the crops’ productivity during both seasons, winter (Rabbi) and summer (Kharif), in Pakistan, thus leading to a decline (an increase) in NFR. Future increases in temperature will be harmful and may lead to significant loss in the revenue amount. The analysis of adaptation techniques exhibits beneficial impacts on the NFR and it is concluded that adaptations are helpful tool for the farmers to minimize revenue loss.
