`Lack of geo-spatial zoning hampers agricultural productivity`
ISLAMABAD: The country`s agriculture production is suffering due to lack of rapid decision-making and planning by the relevant authorities, found a joint study conducted by the Pakistan Agriculture Research Council (PARC) and the International Maize and Wheat Improvement Centre (CIMMYT).[TOP]
The `Cropping pattern zonation of Pakistan` goes on to add that despite the regular updating of provincial and national crop data, geospatial zoning of cropping sequences has not always received due attention in the country.
The cropping analysis of Rabi season indicated that the 25 million tonnes of wheat produced every year in Pakistan is still not enough to meet the country`s needs despite the fact that the country is the world`s seventh-largest producer of wheat.
Wheat is grown on over 75 per cent of the cropped area of 104 districts nationwide. Wheat grain yield varies considerably by land type, irrigation source and rainfall in different ecologies.
The study of the data for 25 major and minor crops growth in 144 districts of the four provinces was conducted to revisit previous zoning initiatives and map sequences of seasonal crops for rapid decision making and allocation of agricul-ture and natural resources in the country. The study addresses challenges and risks for f arm productivity and profitability, according to CIMMYT country representative and co-author of the publication Dr Muhammad Imtiaz.
`With rising temperatures, more erratic rainfall and frequent weather extremes, cropping pattern decisions are of the utmost importance for risk mitigation and adaptation,` he added. With climates characterised increasingly by higher temperatures, erratic rainfall, and more frequent weather extremes, cropping pattern decisions are of the utmost importance for risk mitigation and adaptation.
In particular, farmers in recent times have f aced increasing aridity, more erratic rains, and unpredictable energy shortages, challenges that undoubtedly impact on their decisions regarding the type and extent of crops to grow, it says.
Pakistan`s main crops wheat, rice, cotton and sugarcane account for nearly three-quarters of national crop production. Various food and non-food crops are grown in Rabi, the dry winter season between OctoberMarch, and Kharif, the summer season characterised by high temperatures and monsoon rains.
Typically, more than one crop is grown in succession on a single field each year; however, despite its intensity, farming in Pakistan islargely traditional or subsistence agriculture dominated by the food grains, according to PARC Principal Scientific Officer, Climate, Energy and Water Research Institute Rozina Naz.
`Farmers face increasing aridity and unpredictable weather conditions and energy shortage challenges that impact on their decisions regarding the type and extent of crops to grow,` said Naz, who is involved in executing the whole study. `Crop pattern zoning is a prerequisite for the best use of land, water and capital resources.
The study findings indicated cotton-wheat as a major sequence in the southern districts of Punjab and Khyber Pakhtunkhwa, central districts of Sindh, and western districts of Balochistan. The ricewheat rotation prevails in northeastern districts of Punjab and northwestern and southern districts of Sindh.
The maize-wheat rotation is found in most of the KP districts, four districts of Punjab, and three districts of Balochistan. The sugarcane-wheat patternis found mainly in four districts of Punjab, and single districts of KP, Sindh and Balochistan.
Other minor cropping patterns observed in different districts are rice-chickpea, pulses-chickpea, pulses-wheat, sorghum-wheat and sesame-barley.
