Adoption and impacts of zero tillage as a resource conserving technology in the irrigated plains of South Asia AgEcon
Erenstein, Olaf; Farooq, Umar; Malik, R.K.; Sharif, Muhammad.
The recent stagnation of productivity growth in the irrigated areas of the Indo-Gangetic Plains of South Asia has led to a quest for resource-conserving technologies that can save water, reduce production costs and improve production. The present synthesis of two detailed country studies confirmed widespread adoption of zero tillage (ZT) wheat in the rice-wheat systems of India’s Haryana State (34.5% of surveyed households) and Pakistan’s Punjab province (19%). The combination of a significant “yield effect” and “cost-saving effect” makes adoption worthwhile and is the main driver behind the rapid spread and widespread acceptance of ZT in Haryana, India. In Punjab, Pakistan, adoption is driven by the significant ZT-induced cost savings for wheat...

Adoption and Impacts of Zero-Tillage in the Rice-Wheat Zone of Irrigated Punjab, Pakistan AgEcon
Farooq, Umar; Sharif, Muhammad; Erenstein, Olaf.
This study documents the adoption and impacts of zero-tillage (ZT) wheat in the ricewheat systems of Pakistan’s Punjab province primarily drawing on a detailed empirical survey of 458 rice-wheat farmers. Our random stratified sample revealed 19% to be ZT wheat adopters and a similar share of the wheat area in the surveyed communities to be under ZT. The study suggests that diffusion has stagnated and also flags the issue of disadoption (14%). ZT adopters, non-adopters, and disadopters differ significantly in terms of their resource bases, with adopters typically showing the most favorable values. ZT drastically reduces tractor operations in farmers’ ZT wheat fields from an average of 8 passes to a single pass, implying a saving of 7 tractor hours and 35...

Basin-level use and productivity of water: examples from South Asia AgEcon
Molden, David J.; Sakthivadivel, Ramasamy; Habib, Zaigham.
Discusses and illustrates concepts for identifying ways of improving productivity of water within basins. The results of applying a water accounting procedure to four sub-basins in South Asia (Bhakra in India; Chishtian in Pakistan; Huruluwewa in northern Sri Lanka; and Kirindi Oya in southern Sri Lanka) are presented. The methodology used identifies the quantities and productivity of various uses of water within a basin. This information is then used to identify the water-saving potential, and the means of improving the productivity of the managed supplies.

Compositional studies and biological activities of some mash bean (Vigna mungo (L.) Hepper) cultivars commonly consumed in Pakistan Biol. Res.
Zia-Ul-Haq,Muhammad; Ahmad,Shakeel; Bukhari,Shazia Anwer; Amarowicz,Ryszard; Ercisli,Sezai; Jaafar,Hawa ZE.
BACKGROUND: In recent years, the desire to adopt a healthy diet has drawn attention to legume seeds and food products derived from them. Mash bean is an important legume crop used in Pakistan however a systematic mapping of the chemical composition of mash bean seeds is lacking. Therefore seeds of four mash bean (Vigna mungo (L.) Hepper, family Leguminoseae) cultivars (NARC-Mash-1, NARC-Mash-2, NARC-Mash-3, NARC-Mash-97) commonly consumed in Pakistan have been analyzed for their chemical composition, antioxidant potential and biological activities like inhibition of formation of advanced glycation end products (AGE) activity and tyrosinase inhibition activity. RESULTS: The investigated cultivars varied in terms of biochemical composition to various...

Demand for High-value Secondary Crops in Developing Countries: The Case of Potatoes in Bangladesh and Pakistan AgEcon
Bouis, Howarth E.; Scott, Gregory.
Secondary crops are of increasing interest to policymakers and planners in developing countries because of a desire to diversify economic activities and because of their proven potential to raise farm incomes and rural employment. To assess this potential, basic information on the demand characteristics for these crops is required. But, given the large number of possible crops to be studied, policy analysts require an estimation procedure that is less data-intensive and time-intensive than standard econometric estimation procedures. In this paper, a relatively new, low-cost procedure, based on demand for food characteristics, is applied, illustrating its usefulness for analysis of demand for potatoes in Bangladesh and Pakistan. In Asia, the potato should...

Determinants of Public Health expenditures in Pakistan AgEcon
Abbas, Faisal; Hiemenz, Ulrich.
This study describes the macroeconomic determinants of health care spending in a broad context using time series data from Pakistan on economic, demographic, social, and political variables. The data spans a period from 1972- 2006 and was analyzed using cointegration and error correction approaches. All variables were found to be first difference stationary and the results confirm the presence of one cointegrating vector. This proves the existence of a long-run relationship between public health care expenditures and the other variables used in the model. The income elasticity of public health care expenditures is estimated at 0.23. As this value is less than unity it suggests that, contrary to most of the Organization for Economic Co-operation and...

Distribution of Benefits and Adoption of Bt Cotton in Pakistan: Ex-ante Analysis AgEcon
Nazli, Hina; Sarker, Rakhal; Meilke, Karl D.; Orden, David.
This poster presents the potential impact of Bt cotton adoption in Pakistan. The size and distribution of economic benefits from the commercial adoption of Bt cotton in Pakistan are examined under four hypothetical scenarios. The adjusted economic surplus model is used to measure total benefits and their distribution between producers, consumers and technology innovators. To account for uncertainty in key parameters, the stochastic simulation techniques is applied. The results show that the total net benefits of adopting Bt cotton in Pakistan are large. As a result of increase in production, farmers get considerable benefits despite a decline in price. The share of benefits to innovators is small. The results indicate that the total cost of adopting latest...

Economic Performance of Bt Cotton Varieties in Pakistan AgEcon
Nazli, Hina; Sarker, Rakhal; Meilke, Karl D.; Orden, David.
Farmers in Pakistan have been growing cotton that contains the first generation of Bt gene since 2002. The cultivation of these varieties, although formally unapproved and unregulated, increased rapidly after 2005. In 2007, nearly 60 percent of the cotton area was under BT varieties. This paper examines the economic performance of Bt cotton in Pakistan based on data collected through a structured questionnaire survey in January-February 2009 in two districts (Bahawalpur and Mirpur Khas). The extent of the impact of Bt cotton on costs of production and yield gains are different across the two districts with their diverse agro-climatic conditions and pest pressures. Seed expenditures increase in both districts, but a decline in the number of bollworm sprays...

Effect of different pruning intensities on the growth of Acacia nilotica (Kikar) Agrociencia
Siddiqui,Tahir; Fattakh Nawaz,Muhammad; Ahmed,Irfan.
In many species, natural pruning is never a satisfactory option if production of clear wood is a management objective. Acacia nilotica is well adapted specie to the arid and semiarid climate of Pakistan and plays an important role in rural economy of the country. Traditional pruning is carried out to maximize the amount of clear-wood production but the effect of this practice on tree growth, still unknown. So a preliminary pruning trial was conducted at two different sites, UAF and PARS, in Faisalabad- Pakistan. All pruning treatments resulted in reduction in diameter growth. However, significant reduction in diameter growth was observed when crown removal was more than 40 %. A taper study was done by taking diameter measurements at different heights. The...

Effects of exchange rate and trade policies on agriculture in Pakistan AgEcon
Dorosh, Paul A.; Valdes, Alberto.
This report on Pakistan is one of a series of country studies undertaken by the International Trade and Food Security Program are IFPRI on trade and macroeconomic policies. Other studies in this series include research reports on Colombia, Argentina, Nigeria, Zaire, and the Philippines, and collaborative work with the World Bank on this tonic in several other countries in Asia, Africa, and Latin America. The findings from this research have vividly shown the need to analyze the effects of policy interventions in agriculture in developing countries in an economic-wide framework. There is now an overwhelming body of evidence showing that trade and exchange rate policies have, in most countries, had a far greater impact, generally adverse, on agricultural...

Genetic diversity associated with agronomic traits using microsatellite markers in Pakistani rice landraces Electron. J. Biotechnol.
Pervaiz,Zahida Hassan; Rabbani,M. Ashiq; Khaliq,Ishtiaq; Pearce,Stephen R; Malik,Salman A.
Genetic diversity underlies the improvement of crops by plant breeding. Land races of rice (Oryza sativa L.) can contain some valuable alleles not common in modern germplasm. The aim here was to measure genetic diversity and its effect on agronomic traits among rice land-race genotypes grown in Pakistan. Diversity was measured using thirty-five microsatellite markers and seventy-five genotypes. Among the markers used a total of 142 alleles were detected at 32 polymorphic SSR loci, while three loci were monomorphic in Pakistani rice landraces. The number of alleles identified by each marker ranged from 2 to 13 with a mean of 4.4. Size differences between the smallest and largest alleles varied from 11bp to 71bp. Polymorphism information content ranged from...

Human Capital Productivity, and Labor Allocation in Rural Pakistan AgEcon
Fafchamps, Marcel; Quisumbing, Agnes R..
This paper investigates whether human capital affects the productivity and labor allocation of rural households in four districts of Pakistan. The investigation shows that households with better-educated males earn higher off-farm income and divert labor resources away from farm activities toward nonfarm work. Education has no significant effect on productivity in crop and livestock production. The effect of human capital on household incomes is partly realized through the reallocation of labor from low-productivity activities to nonfarm work. Female education and nutrition do not affect productivity and labor allocation in any systematic fashion, a finding that is consistent with the marginal role women play in market-oriented activities in Pakistan. As a...

Identifying Asset Poverty Thresholds – New methods with an application to Pakistan and Ethiopia AgEcon
Naschold, Felix.
Understanding how households escape poverty depends on understanding how they accumulate assets over time. Therefore, identifying the degree of linearity in household asset dynamics, and specifically any potential asset poverty thresholds, is of fundamental interest to the design of poverty reduction policies. If household asset holdings converged unconditionally to a single long run equilibrium, then all poor could be expected to escape poverty over time. In contrast, if there are critical asset thresholds that trap households below the poverty line, then households would need specific assistance to escape poverty. Similarly, the presence of asset poverty thresholds would mean that short term asset shocks could lead to long term destitution, thus...

Increased water charges improve efficiency and equity in an irrigation system Ecology and Society
Bell, Andrew Reid; Department of Environmental Studies, New York University; ab6176@nyu.edu; Ward, Patrick S.; International Food Policy Research Institute (IFPRI), Washington, D.C.; p.ward@cgiar.org; Shah, M. Azeem Ali; International Water Management Institute (IWMI), Lahore, Pakistan; Lahore University of Management Sciences (LUMS), Pakistan; a.shah@cgiar.org.
Conventional wisdom in many agricultural systems across the world is that farmers cannot, will not, or should not pay the full costs associated with surface water delivery. Across Organisation for Economic Co-operation and Development (OECD) countries, only a handful can claim complete recovery of operation, maintenance, and capital costs; across Central and South Asia, fees are lower still, with farmers in Nepal, India, and Kazakhstan paying fractions of a U.S. penny for a cubic meter of water. In Pakistan, fees amount to roughly USD 1-2 per acre per season. However, farmers in Pakistan spend orders of magnitude more for diesel fuel to pump groundwater each season, suggesting a latent willingness to spend for water that, under the right conditions, could...

Is Greater Decisionmaking Power of Women Associated With Reduced Gender Discrimination in South Asia? AgEcon
Smith, Lisa C.; Byron, Elizabeth.
Recent research has shown that improving women’s decisionmaking power relative to men’s within households leads to improvements in a variety of well-being outcomes for children. In South Asia, where the influence of women’s power is particularly strong, these outcomes include children’s nutritional status and the quality of feeding and health care practices. Focusing on nutritional status, this paper presents the results of a study investigating whether increases in women’s power have a stronger positive influence on the nutritional status of their daughters than their sons. If so, then increasing women’s power not only improves the well-being of children as a group, but also serves as a force to reduce long-standing discrimination that undermines female...
