Agricultural technologies can increase global crop yields by 67pc

Pakistan, which has an agrarian economy, is not equipped to adapt to climate change because of its low technological and resource base.

It has suffered a loss of billions because of the floods in recent years. A new strategy is required to mitigate and adapt to the impacts of climate change.

The increased demand for food due to population and income growth and the impacts of climate change on agriculture will ratchet up the pressure for increased and more sustainable agricultural production to feed the planet.

A new report released on Wednesday by London-based International Food Policy Research Institute (IFPRI) measures the impacts of agricultural innovation on farm productivity, prices, hunger, and trade flows as we approach 2050 and identifies practices which could significantly benefit developing nations.

The International Food Policy Research Institute (IFPRI) seeks sustainable solutions for ending hunger and poverty.

The IFPRI was established in 1975 to identify and analyse alternative national and international strategies and policies for meeting the food needs of the developing world, with particular emphasis on low-income countries and on the poorer groups in those countries. “The book, Food Security in a World of Natural Resource Scarcity: The Role of Agricultural Technologies, released today, examines 11 agricultural practices and technologies and how they could help farmers around the world improve the sustainability of growing three of the world’s main staple crops – maize, rice, and wheat,” the report said.

Using a first-of-its-kind data model, the IFPRI pinpoints the agricultural technologies and practices that can most significantly reduce food prices and food insecurity in developing nations. The study profiles 11 agricultural innovations: crop protection, drip irrigation, drought tolerance, heat tolerance, integrated soil fertility management, no-till farming, nutrient use efficiency, organic agriculture, precision agriculture, sprinkler irrigation, and water harvesting.

The findings from the book indicate that no-till farming alone could increase maize yields by 20 percent, but also irrigating the same no-till fields could increase maize yields by 67 percent in 2050.

Nitrogen-use efficiency could increase rice crop yields by 22 percent, but irrigation increased the yields by another 21 percent.

Heat-tolerant varieties of wheat could increase crop yields from a 17 percent increase to a 23 percent increase with irrigation.

Yet, no single silver bullet exists. “The reality is that no single agricultural technology or farming practice will provide sufficient food for the world in 2050,” said Mark Rosegrant, lead author of the book and director of IFPRI’s Environment and Production Technology Division. “Instead we must advocate for and utilise a range of these technologies in order to maximise yields.”

However, it is realistic to assume that farmers in the developing world and elsewhere would adopt a combination of technologies as they become more widely available. If farmers were to stack agricultural technologies in order of crop production schedules, the combination of agricultural technologies and practices could reduce food prices by up to 49 percent for maize, up to 43 percent for rice, and 45 percent for wheat due to increased crop productivity. The technologies with the highest percentage of potential impact for agriculture in developing countries include no-till farming, nitrogen-use efficiency, heat-tolerant crops, and crop protection from weeds, insects, and diseases.

The anticipated negative effects of climate change on agricultural productivity as well as projected population growth by 2050, suggest that food insecurity and food prices will increase. For example, climate change could decrease maize yields by as much as 18 percent by 2050–making it even more difficult to feed the world if farmers cannot adopt agricultural technologies that could help boost food production in their regions.

“One of the most significant barriers to global food security is the high cost of food in developing countries,” Rosegrant explained. “Agricultural technologies used in combinations tailored to the crops grown and regional differences could make more food more affordable – especially for those at risk of hunger and malnutrition in developing countries.”

However, based on current projections, stacked technologies could reduce food insecurity by as much as 36 percent. Making this a reality, however, depends on farmers gaining access to these technologies and learning how to use them. This underscores the need for improved agricultural education to ensure that farmers are able to use the best available technologies for their region and resources.

The IFPRI highlights three key areas for investments prioritising effective technology use: increasing crop productivity through enhanced investment in agricultural research; developing and using resource-conserving agricultural management practices such as no-till farming, integrated soil fertility management, improved crop protection, and precision agriculture.

Zinc: Importance and Current situation

Zaghum Sattar & Abdul Saboor Butt

Institute of soil & Environmental Sciences, University of Agriculture, Faisalabad

Zinc (Zn) is among those minerals that were first considered as essential for plants, animals and human. Zn is a basic essential trace mineral element for normal healthy growth in plants, animals and humans that uptake as a divalent cation (Zn²⁺) by plants. Zn is playing principal metabolically role in plants and required in the carbonic enzyme present in all photosynthetic tissues, and also required for chlorophyll biosynthesis. Zinc is one of the essential micronutrient for the normal healthy growth and reproduction of crop plants. Zn plays an important role in plant metabolism by influencing the activities of enzymes, hydrogenase and carbonic anhydrase, stabilization of ribosomal fractions and also synthesis of cytochrome.  Zn also activate plant enzymes involved in carbohydrate metabolism, integrity maintenance of cellular membranes, synthesis of nucleic acids and specific proteins, regulate auxin synthesis and pollen formation. The regulation of the gene expression required for the tolerance of environmental stresses in plants also depend on the Zn.Zinc deficiency involves in the abnormalities development in plants as deficiency symptoms such as stunted growth, chlorosis and smaller leaves, spikelet sterility. Zn deficiency can also adversely affect the quality of harvested products; plants susceptibility to injury by high sunlight or temperature intensity and to infection by fungal diseases can also increase. A zinc deficiency affects the capacity for water uptake and transport in plants. Zn involves in the synthesis of tryptophan which is a precursor of IAA, and in the production of growth hormoneauxin. Zinc deficiency is common in humans, animals and plants. More than 30% world’s population suffers from Zn deficiency. Zinc deficiency is found to be more common in developing countries due to low Zn in their diet. Zinc plays a part.in the basic roles of. Cellular functions in all living organisms and also involved in the human immune system. The optimum dietary intake for human adults is 12-15 mg Zn per day. Zinc acts as a catalytic or structural component in various body enzymes.Unsatisfactory intake and improper absorption of Zinc in the body may cause deficiency of Zn.  Zn malnutrition in humans can result in many fatal and other diseases like hair and memory loss, skin problems and weakness in eye side and body muscles. Insufficient intake of Zn during pregnancy in women also causes stunted brain development of the fetus. Infertility has also been observed in Zn deficient men. Zinc deficiency may cause congenital diseases like Acrodermatitis enteropathica. According to FAO/WHO recommendations an average male need 11 mg of Zn daily while an average female needs 9 mg of Zn. During pregnancy and lactation, the female needs 13 mg to 14 mg of Zn daily. Infants from 7 months to 3 years need 3 mg, 4 to 8 years need 5 mg and children from 9 to 13 years need 8 mg of Zn daily. In Pakistan, Zn deficiency is common in children and in women.Trace elements such as Zn are contained in all soils in measurable amounts. However, these concentrations can vary considerably. The overall mean total Zn concentration in soil is around 55 mg Zn kg^-1. A typical range of Zn in soils is from 10 to 300 mg Zn kg^-1. These values do not include contaminated soils, which may have much higher zinc concentrations.However, plant available Zn is very low as compared to its total amount. For a better Zn nutrition of human beings, cereal grain should contain around 40-60 mg Zn kg^-1 where current situation is 10-30 mg Zn kg^-1. Soils with low zinc availability for plant uptake represent nearly half of the cereal-growing areas of the world. The countries most affected by zinc deficient soils are Pakistan, India, Iran, China and Turkey with 50-70% of arable land classified as zinc deficient.

Indian family makes a breakthrough in hydroponics

by Mike Adams

Hydroponics, the practice of growing plants in water instead of soil, received a giant lift from a New Delhi family that created a purely organic nutrient mix that has sustained tomatoes and Arjun.

An Indian hobbyist has created a purely organic nutrient mixture for growing plants in water. Although it is still an evolving science, hydroponic agriculture (growing plants in water solution rather than soil) is spreading fast the world over. The nutritional requirement of the plants in this system of soilless farming is met by the nutrient mixtures, called hydroponics fertiliser mixtures, added to the water in which the plant roots are kept submerged. These mixtures are made of chemical plant nutrients. A breakthrough has now been achieved by an Indian hydroponics hobbyist in creating a purely organic nutrient mixture for growing plants in water. This wholly chemical-free plant growth solution has been tested successfully for growing several plants, including common vegetables like tomato and arbi and some high value medicinal plants like Brahmi, Arjun and Cineraria. Indeed, a good deal of research is underway in this system of soilless farming in the US and Europe but not much headway has been made anywhere in organic hydroponics. Of course, some hydroponics enthusiasts abroad have been experimenting with various kinds of organic manures and mixtures of plants, but successful and commercially viable organic hydroponics models are still not available. His daughter, Shweta Singh, a Delhi University botany student, has been assisting him in discovering and further improving the biofertiliser mixture for growing plants in ordinary water. “I will work on it for a couple of years more before thinking of launching commercial production of this bio-fertiliser for hydroponics. However, if some government organisation, such as the Indian Council of Agricultural Research (ICAR), comes forward, I am willing to cooperate with it in promoting organic hydroponics in India,” he says. He believes that nearly 200 commercially important plants can be grown by hydroponics technique.

10 tips for companion planting for natural pest control and organic sustainability

Companion planting for pest control and to encourage plants to grow with more vigor has fascinated men for centuries; however, few backyard gardeners know how to use these natural methods for organic sustainability and how to improve your garden. Plants that work together to help one another grow; plants that repel insects for organic pest management; and plants that repel other plants for natural herbicide control are of great value to both small backyard gardeners and commercial growers.
Certain protective botanicals don’t always act instantaneously, and must be planted several years or seasons in advance to be of utmost cumulative effect. For example, companion planting pest control using marigolds to prevent nematode growth should be done at least one season ahead before expecting to see great results.

It’s important to remember that both secretions and odors from various plants are valuable traits for organic pest control and companion planting where repelling or attracting certain aspects and effects is attempted.

Ten easy companion planting tips for to use now

Companion planting for chemical free pesticides and organic sustainability is a huge subject that can take years to master; however, there are a few easy things you can do in your own garden right now to make use of this intriguing method of gardening.

1. Protect carrots by planting them with leeks to repel both carrot and onion flies. They won’t even lay their eggs and your yield will increase tremendously.

2. Growing radishes or kohlrabi? Plant them with lettuce to repel earth flies that hate the smell of lettuce and make them take flight.

3. Aphids will injure almost all plants, causing headaches for gardeners everywhere. To repel aphids, plant nasturiums around broccoli and bunches of chives among sunflowers and tomatoes to discourage infestations.

4. Ladybugs are natural enemies to aphids and are excellent for use in organic pest management. Order ladybugs in bulk online or buy them from gardening centers. If you’re wondering how to improve your garden and reduce the aphid population, this is one of the most effective methods of doing so.

5. Asparagus and tomatoes complement one another and improve the vigor of both plants. Place a row of asparagus between two rows of tomato plants.

6. Beans and potatoes work in concert for organic pest control. Planting bush beans with potatoes in alternating rows protects the spuds from the Colorado potato beetle and the beans from the Mexican bean beetle.

7. Broccoli and other cruciferous vegetables belonging to the cabbage family do well when companion planted with celery, dill, peppermint, sage and rosemary; as well as potatoes, onions and beets.

8. Repel moles around a vegetable garden with a border of castor beans; mice with a border of daffodils; and yarrow makes a wonderful boarder for an herb garden as it encourages the growth of essential oils in the herbs.

9. Remember that companion planting for pest control includes keeping those cute little rabbits out of the garden. Onions repel rabbits and can be inter-planted with peas, beans, lettuce and cabbage.

10. If your garden attracts raccoons, plant corn and pumpkins together so that the large pumpkin leaves grow around the base of the corn stalks. Cayenne pepper sprinkled on the corn silk will also act as a deterrent.

Because some plants are poisonous, it’s important to keep unattended young children away from the garden. Natural organic pest control may be a complex subject; however, there are many simple things you can do in to improve your garden for increased vegetable yield and organic sustainability.

Pakistan participates in Fruit Logistica-2014 Fair in Berlin

As many as 13 Pakistani companies participated in the world's leading international fresh produce trade fair, Fruit Logistica-2014, this year in Berlin that ended on Saturday. Pakistani exhibitors were optimistic of substantial increase in export of fresh produce from Pakistan as they made good contacts with the international buyers of fruit and vegetable products.
Buyers from Russia showed keen interest in Pakistani potatoes whereas Pakistani mangoes have also made inroads into EU market with increase in shelf life through better processing technology and other corrective measures. Earlier, Pakistan Ambassador to Germany Abdul Basit visited Pakistan Pavilion along with Commercial Counsellor, Dr Erfa Iqbal and met with Pakistani exhibitors.
He also held a meeting with the delegation of mango growers and exporters of Pakistan, who put up their stalls under the umbrella of UNIDO and the USAID. Both the organisations are running projects of increasing income through improvement of quality and better yield and generating additional employment's in the major mango-growing areas of South Punjab and Northern Sind.
The Ambassador said the world's leading trade fair provides great opportunity for promotion, development and marketing of fresh fruit and vegetable products. He emphasised the need of intensive interaction between farmers and exporters to up-grade the quality and increase yield of fresh products. He said there is a growing market for Pakistani fruits, especially mangoes and Kinnow/mandarin. Pakistani exporters should give due importance to fruit processing and packaging for longer preservation of these perishable products, he added.
He urged the traders to spend sufficient amount of their income on research and development, which is essential to keep pace with the ever changing market trends. The exhibitors expressed their satisfaction over the arrangements made by the Commercial Section of the Pakistan Embassy and the Trade Development Authority of Pakistan. About 2,566 including 2,311 foreign exhibitors from 84 countries presented a comprehensive overview of all levels of fruit and vegetable production and marketing and more than 58,000 trade visitors from 130 countries visited the exhibition and made business contacts besides a large number of general public/end consumers.

GMO challenges: Ministry asked to call crucial meeting

The Federal Law Ministry has finally given a ruling, asking Climate Change Ministry to convene a meeting of National Bio-Safety Committee for granting approval to the long-awaited 15 Genetically Modified Organism (GMO) of cotton varieties for commercialisation, sources revealed.

Well-placed sources revealed to Business Recorder that Textile division had approached Prime Minister Nawaz Sharif after the reportedly delaying tactics by the Climate Change Ministry for convening a meeting of NBC.

Prime Minister on January 16, 2014 constituted a committee comprising Secretary Textile division, Secretary Law and Secretary Climate Change and directed them to hold a meeting within 10 days for resolving the issue. The committee met last week and Law division gave a ruling asking for convening a meeting of NBC to grant approval for commercialisation of cotton seeds, sources maintained.

Certified cotton seed was becoming a serious issue as no BT certified cotton seed would be available for cultivation for the upcoming crop season due to non-approval of GMO cotton varieties by NBC which might encourage the seed-mafia, besides negatively impacting commodity production, official maintained.

Official sources revealed that Pakistan being a signatory to the international Cartagena Protocol on Biosafety had to regulate GMO through establishing a Bio-safety system in the country. NBC and Technical Advisory Committee (TAC) of Pakistan Environmental Protection Agency (PEPA) have responsibility to evaluate, regulate and monitor GMO for lab or field research and their commercial scale production or marketing in the country.

The NBC had not held its meeting since February 2011, which had delayed the regulatory process required to test and approve GMOs crops, said sources, adding that applications submitted by various public and private sectors organisations seeking approval of different GMO crops were yet to be reviewed by the NBC.

Currently only transgenic crop commercially cultivated in Pakistan is cotton and eight BT varieties and one cotton Hybrid were approved by Punjab Seed Council (PSC) in April 2010 and commercialisation certificate was granted by NBC. In February 2012, PSC provisionally approved eight BT varieties (Tarzen-1, MNH-886, NS-141, FH-114, IR-NIBGE-3, CIM-598, Sitara-009, A-One) subject to the grant of commercialisation certificate from the NBC and TAC had to clear cases before consideration in NBC, sources maintained.

BT cotton varieties in Pakistan, which were granted certificate for three years (now expired) included IR-3701, Neelum-121, FH-113, Sitara-008, MG-6, Ali Akbar-703, Ali Akbar 802, IR-1524 and GN Hybrid-2085. BT cotton varieties waiting for commercialisation certificate included Tarzen-1, VH-259, MNH-886, BH-178, NS-141, CIM-599, FH-114, CIM-602, IR-NIBGE-3, FH-118, CIM-598, FH-142, Sitara 009, IR-NIBGE-824, A-One IUB-222, Sayaban-201, Sitara-11M, A-555, KZ-181, Tarzan-2 and CA-12.

Politicians urged to show maturity on Kalabagh Dam issue

Multan Chamber of Commerce & Industry (MCCI) has said that politicians should show their maturity on national issues like Kalabagh Dam, energy crisis, trade with neighbouring countries and achieving the goal of GSP-plus status. MCCI lauded the expression of political maturity and avoiding the politics of avenge by the leaders of the government and the opposition while inaugurating the Thar Coal Power Project worth around Rs 1.5 trillion.

The encouraging gestures of rival politicians have not only made history but also sent very positive signals arousing hopes among the masses and the business community. President of MCCI Khawaja Muhammad Usman has said country has lost a lot due to political conflicts but it seems that now the major political parties have decided to keep national interest and economic development above over the politics.

He said the opposition of nationalists and so-called intellectuals failed to dent the resolve of the government to launch the Thar Coal project, which is highly laudable. Usman said politics in Pakistan seems different now which will help stabilise democracy, boost economy and resolve the energy crisis soon. He asked the government and opposition to forge unity to get the long-awaited Kalabagh Dam (KBD) project started.

The KBD remains victim to politics transforming a technical issue into a hot topic, said Baig Raj, adding that enemies of Pakistan are behind opposition of the most viable project in the country. The so-called scholars and nationalists who are against KBD are dancing on the tunes of their foreign masters who don’t want a stabilise Pakistan, he said.

These elements have helped plunge a country like Pakistan with unmatched resources into darkness for their petty gains, he said. KBD is the best way to have dependable energy otherwise country will never be able to become Asian Tiger and will remain a beggar, said Khawaja Usman.
