Impact of WTO’s Trade Liberalisation on Selected Food Crops in Pakistan

WTO has major implications for almost all the sectors of economy but agriculture sector is the one which is more prone to the implementation of its agreements, particularly the Agreement on Agriculture (AoA). The study intended to evaluate the impact of WTO on domestic ma rket and farm-level prices, production and consumption of major food commodities like wheat and rice and ultimately their impact on the producer’s and consumer’s surpluses. The farm level impact was also evaluated to chalk out the eventual position at farm level with the purpose to identify necessary policies and actions to cope with the new world situation. The study tries to provide a useful guide to the likely impacts of agricultural trade liberalisation. It was found that openness of the economy would affect the domestic demand, supply and consumption along with affecting the producer and consumer surpluses. It was estimated that increased prices would have increased production of wheat which would have generated a gain of producer’s surplus of Rs 10,682 million. On the other hand due to increased wholesale price of wheat, the domestic demand of wheat would have declined and caused a loss to consumer surplus of Rs 12,557 million. Similarly, the increased production of rice would have generated a gain of producer’s surplus of Rs 3,708 million. However, due to increase in the wholesale price of rice, its domestic demand would have declined thus causing a loss to consumers’ surplus. Overall the impact of the increase in the international price of wheat would have resulted in a net loss to Pakistan of Rs 1,875 million during 2004-05 while in case of rice it would have resulted in a gain of Rs 1,215 million in 2004-05.Trade Liberalisation, Food Crops, Export, Consumer Surplus, Comparative Advantage, Free Trade.

Impact of WTO’s Trade Liberalisation on Selected Food Crops in Pakistan

There is a great potential in Pakistan for production of all types of food commodities due to vast natural resource base, covering various ecological and climatic zones. Most of the agricultural commodities produced in the country are consumed by the local population while the rest is exported in the form of primary products and some value added products. Previously, Pakistani products had a good market overseas with no restrictions of quality and quantity but under the changing environment affected by WTO, it is expected that Pakistan will face a strong competition in the agriculture sector from its competitors in the world market. According to the neoclassical trade theory, trade flows and pattern will develop along the lines of comparative advantage and competitiveness that can act as indicators of trade potential and direction. There has been extensive government involvement in the determination of the overall structure of agriculture and its patterns of production, employment and trade. Pakistani government has been intervening in agriculture sector in the past in order to support agricultural production, income supports, ensure food security, improve the balance of trade, reduce consumer prices, address environmental and regional concerns and to pursue sanitary and phyto-sanitary objectives [Hassan (1995)]. Pakistan is a founding member of the General Agreement on Tariffs and Trade (GATT) since its creation. Following the Uruguay Round negotiations, all agricultural products were brought under multinational trade rules by WTO, under the Agreement on Agriculture. This established a framework to begin liberalising agricultural trade through the reduction of import duties (tariffs), trade-distorting production subsidies and export subsidies. Prior to the Uruguay Round, trade in agriculture was highly distorted. Market access for agricultural products was limited as most markets were restricted by physical import barriers. The presence of massive domestic subsidies led to overproduction of temperate crops in the developed countries that led to excess supply, and export subsidies were used to dump the surplus agricultural output in international markets. This resulted in depressed market prices and, in spite of being low-cost producers of agricultural products; developing countries could not compete with the subsidised exports from developed countries

Climate Change and Water Scarcity: The Case of Saudi Arabia

Background: Climate change is expected to bring increases in average global temperatures (1.4°C–5.8°C [34.52°F–42.44°F] by 2100) and precipitation levels to varying degrees around the globe. The availability and quality of water will be severely affected, and public health threats from the lack of this valuable resource will be great unless water-scarce nations are able to adapt. Saudi Arabia provides a good example of how the climate and unsustainable human activity go hand in hand in creating stress on and depleting water resources, and an example for adaptation and mitigation. Method: A search of the English literature addressing climate change, water scarcity, human health, and related topics was conducted using online resources and databases accessed through the University at Albany, State University of New York library web page. Results: Water scarcity, which encompasses both water availability and water quality, is an important indicator of health. Beyond drinking, water supply is intimately linked to food security, sanitation, and hygiene, which are primary contributors to the global burden of disease. Poor and disadvantaged populations are the ones who will suffer most from the negative effects of climate change on water supply and associated human health issues. Examples of adaptation and mitigation measures that can help reduce the strain on conventional water resources (surface waters and fossil aquifers or groundwater) include desalination, wastewater recycling and reuse, and outsourcing food items or “virtual water trade.” These are strategies being used by Saudi Arabia, a country that is water poor primarily due to decades of irresponsible irrigation practices. The human and environmental health risks associated with these adaptation measures are examined. Finally, strategies to protect human health through international collaboration and the importance of these efforts are discussed. Conclusion: International, multidisciplinary cooperation and collaboration will be needed to promote global water security and to protect human health, particularly in low-income countries that do not have the resources necessary to adapt on their own

Air quality in Mecca and surrounding holy places in Saudi Arabia during Hajj: initial survey.

The Arabian Peninsula experiences severe air pollution, the extent and sources of which are poorly documented. Each year in Saudi Arabia this situation is intensified during Hajj, the Holy Pilgrimage of Islam that draws millions of pilgrims to Mecca. An initial study of air quality in Mecca and surrounding holy sites during the 2012 Hajj (October 24-27) revealed strongly elevated levels of the combustion tracer carbon monoxide (CO, up to 57 ppmv) and volatile organic compounds (VOCs) along the pilgrimage route-especially in the tunnels of Mecca-that are a concern for human health. The most abundant VOC was the gasoline evaporation tracer i-pentane, which exceeded 1200 ppbv in the tunnels. Even though VOC concentrations were generally lower during a follow-up non-Hajj sampling period (April 2013), many were still comparable to other large cities suffering from poor air quality. Major VOC sources during the 2012 Hajj study included vehicular exhaust, gasoline evaporation, liquefied petroleum gas, and air conditioners. Of the measured compounds, reactive alkenes and CO showed the strongest potential to form ground-level ozone. Because the number of pilgrims is expected to increase in the future, we present emission reduction strategies to target both combustive and evaporative fossil fuel sources

Short-term association between black carbon exposure and cardiovascular diseases in Pakistan’s largest megacity

This study investigated the association between black carbon (BC) exposure and hospital admissions (HAs) and outpatient department/emergency room (OPD/ER) visits for cardiovascular diseases (CVD) among residents of Karachi, the largest city in Pakistan. We measured daily concentrations of BC in fine particulate matter (PM2.5) and collected records of HAs and OPD/ER visits for CVD from 2 major tertiary care hospitals serving Karachi for 6 weeks continuously during each quarter over 1 year (August 2008–August 2009). We subsequently analyzed daily counts of hospital and BC data over 0–3 lag days. Daily mean BC concentrations varied from 1 to 32 µg/m3 . Results suggest that BC concentrations are associated with CVD HAs and OPD/ER visits. However, associations were generally only observed when modeled with BC from Tibet Center, the commercial-residential site, as compared to Korangi, the industrial-residential site. Overall, low statistical significance suggests that while BC may be a valuable indicator for CVD health risks from combustion-derived particles, further evaluation of the constituents of PM2.5 and their relative contributions to CVD health impacts is necessary

Traversing the Waste Spectrum: Unveiling Pakistan's MSW Landscape and Solutions

Municipal solid waste (MSW) management must be sustainable in order to meet the Sustainable Development Goals (SDGs) and address health, environmental, and disposal challenges caused by the vast amounts of trash generated. MSW management going wrong puts locals in danger. In Pakistan, the production of municipal solid trash is rising daily. Urban settlers and other organizations gather a lot of waste in various forms, usually defiling and making our surroundings uninviting.  Due to the indiscriminate dumping of various wastes, the soil quality in the metropolitan area has decreased as a result of solid and liquefied waste disposal. Significant environmental concerns regarding soil and water pollution arise from transferring contaminated garbage and mixed fluid outside of waste disposal borders. The impacts of municipal garbage disposal on soil and water quality at open waste dumping sites were the main focus of this review. Using a soil and water quality index, in many regions of the world especially in regions where waste management practices are insufficient, the contamination of soil and water owing to incorrect municipal solid waste disposal is a serious environmental hazard. Open dumping, unregulated landfilling, and illegal dumping are examples of improper waste disposal practices that can result in pollution that affects the quality of the soil and water. They must also seek to identify sustainable waste management solutions. The effect of these emitted gaseous emissions has, however, been thoroughly researched. To safeguard the environment and public health, quick action must be made to control trace element pollution

Effect of air pollution on daily morbidity in Karachi, Pakistan

Levels of daily particulates (PM2.5) were monitored at two sites in Karachi, Pakistan. One site (Korangi) is an industrial and residential neighborhood, while the other (Tibet Center) is a commercial and residential area near a major highway. Monitoring was done daily for a period of six weeks during spring, summer, fall and winter. Particulate levels were extraordinarily high, with the great majority of days falling into the “unhealthy for sensitive groups” or “very unhealthy” categories. The mean PM2.5 levels in Karachi exceeded the WHO’s 24 h air quality guideline almost every day and often by a factor of greater than 5-fold. Daily emergency room (ER) visits and hospital admissions for cardiovascular diseases were obtained by review of medical records at three major tertiary and specialized hospitals. ER and hospitalizations were reported relative to days in which the concentration of PM2.5 was less than 50mg/m3 , and by 50 mg/m3 increments up to 300mg/m3 . There were statistically significant elevations in rates of hospital admissions at each of the PM2.5 categories at the Korangi site, and at concentrations .150mg/m3 at the Tibet Center site. ER visits were significantly elevated only at PM2.5 concentrations of between 151 and 200 mg/m3 at both sites. These results show that the extremely elevated concentrations of PM2.5 in Karachi, Pakistan are, as expected, associated with significantly elevated rates of hospital admission, and to a lesser extent, ER visits for cardiovascular disease

Characterization of carbon monoxide, methane and nonmethane hydrocarbons in emerging cities of Saudi Arabia and Pakistan and in Singapore

We investigate the composition of 63 C2-C10 nonmethane hydrocarbons (NMHCs), methane (CH4) and carbon monoxide (CO), in Jeddah, Mecca, and Madina (Saudi Arabia), in Lahore, (Pakistan), and in Singapore. We established a database with which to compare and contrast NMHCs in regions where ambient levels and emissions are poorly characterized, but where conditions are favorable to the formation of tropospheric ozone, and where measurements are essential for improving emission inventories and modeling. This dataset will also serve as a base for further analysis of air pollution in Western Saudi Arabia including, but not limited to, the estimation of urban emissions and long range pollution transport from these regions. The measured species showed enhanced levels in all Saudi Arabian cities compared to the local background but were generally much lower than in Lahore. In Madina, vehicle exhaust was the dominant NMHC source, as indicated by enhanced levels of combustion products and by the good correlation between NMHCs and CO, while in Jeddah and Mecca a combination of sources needs to be considered. Very high NMHC levels were measured in Lahore, and elevated levels of CH4 in Lahore were attributed to natural gas. When we compared our results with 2010 emissions from the MACCity global inventory, we found discrepancies in the relative contribution of NMHCs between the measurements and the inventory. In all cities, alkenes (especially ethene and propene) dominated the hydroxyl radical (OH) reactivity (kOH) because of their great abundance and their relatively fast reaction rates with OH
