Promoting Food Security For Improved Rural Livelihoods in Nigeria


KEYNOTE PAPER DELIVERED AT THE 201 3 WORLD ENVIRONMENT DAY CELEBRATION IN FEDERAL UNIVERSITY OF TECHNOLOGY, OWERRI ON JUNE 27TH  2013.
By
PROFESSOR ALFRED IHEKORONYE, fnifst
EXECUTIVE DIRECTOR, AGRO DEVELOPMENT TECHNOLOGY INITIATIVE NIGERIA LIMITED

INTRODUCTION: Beyond Diagnosis And Prescription To Focused Action.
The appalling severity of Africa's food insecurity and how best to escape it has in recent years and even months been the subject of many meetings at all levels in the region. Most notable fora have been the landmark African Union summits of Maputo in January 2003 and at Sirte in February 2004, which now serve as reference points for all else that is discussed on this issue.
Africa is also party to global commitments made under the plan of Action of the UN's 1996 world Food summit organised by FAO and seeks to achieve the Millennium Development Goals set under the auspices of the United Nations. It may also be noted that the Maputo and Sirte commitment on areas of action cover the entire spectrum of agriculture and food security interventions from farm, through post-harvest and processing to marketing and trade; they also cover enabling conditions for success such as financing, human capacities research and technology.
But what is Food Security and what are its objectives?
The Food and Agriculture Organization of the United Nations (FAO) noted that Food Security exists when all people at all times have physical and economic access to sufficient, safe and nutritious food to meet their dietary needs and food preferences for an active and healthy life.
The broad objective of a Food Security Programme is to contribute to sustainable improvements in the National Food Security, through rapid increase in productivity and food production on an economically and environmentally sustainable basis, reduce year to year variability in agricultural production, and improve people's access to food.
National Special Programme for Food Security in Nigeria
§  NSPFS is an integrated agricultural production programme seeking to increase household food security for poor farming communities in Nigeria.
§  NSPFS presently covers 1 09 sites, one site for each senatorial district in the country.
§  NSPFS is exclusively funded by the Federal Government of Nigeria.
§  NSPFS is farmer driven as all activities are based on farmer's demands.
§  The farmers demand can be summarized as follows:
-     Timely provision of agricultural inputs;
-     Access to credit to acquire inputs.
§  The NSPFS mandate is to respond to these farmer driven demands in a timely and coordinated fashion.

It implies access to the desired quantity and quality of food at all times by every man, woman and child in the nation.
NSPFS was formally launched in Nigeria on the 1 8"1 of March, 201 3 at Buruku village, Kaduna State. The project consists of the following: irrigation, soil fertility improvement, crop intensification, animal production and health, aquatic and artisan fisheries, marketing, processing and processing components. This programme is wholly owned and funded by the Federal Government of Nigeria in a partnership arrangement with FAO providing administrative and technical support. National ownership is a key element of the Nigerian programme.
The broad objective of the programme is to contribute to sustainable improvements in the national food security through rapid increase in productivity and food production on economically and environmentally, sustainable basis, reduce year to year variability in agricultural production, and improve people's access to food.
Food security is crucial to sustainable human development. It rests on a tripod of food availability, affordability and accessibility.
Women participation in the Food Security Programme
Please permit me if I wander off a little bit and reflect on some of the attitudes of the political leadership in Nigeria to the issue of women's participation in the Special Programme of Food Security. It is a topic which we tend to relegate to seminars and workshops such as this. Very few of us give consideration to the fact that women play the most significant role in food production and must therefore be seen as occupying a strategic position in our drive to achieve Food Security in Nigeria. Although there is diversity in household production patterns, women in Nigeria spend up to two-thirds of their time in traditional agriculture and marketing, with their work hours tending to exceed those of men. Women in rural areas grow at least 50-percent of the nation's food. They work in all aspects of cultivation, including planting, weeding, applying fertilizer and harvesting as well as post-harvest activities. They are also involved in poultry and livestock production. While women produce much of the nation's food supply and are the backbone of food production and provisioning for family consumption, their productivity is generally low and based on long work hours on small landholdings. Their names may not always appear in the headlines because they are not involved in the contest for 2015; and yet to any serious thinker, they are the ones promoting and sustaining better rural livelihoods. May the Almighty God bless them.
Government's new paradigm shift:
From Food Security to Agricultural Transformation Agenda
In an address presented at the 36'h Annual conference of the Soil Science Society of Nigeria held at the University of Nigeria, Nsukka, the Minister of Agriculture commended the commitment of President Goodluck Jonathan for the launch of "Agriculture Transformation Action Plan"(ATAP). The ATAP has the objective of improving the agricultural sector and boosting food production. Government is committed to increased investment in food and agriculture production with the following as its policy thrust:
Ø   Creation of more agriculture and rural employment opportunities to increase the income of farmers and rural dwellers through modernization of production and creation of an agricultural sector that is responsive to the demands and realities of the Nigerian economy.
Ø   Fostering effective linkage with industry to achieve maximum value addition/processing for export.
Ø   Under the Agricultural Transformation Action Plan, fertilizers and other inputs will be sold directly to farmers.
Ø   Government will no longer be directly involved in the procurement and distribution of fertilizers.
Additionally, and because Nigeria is rated as the world's largest cassava producer, for example, a Cassava Transformation Plan, using a value-chain development approach has been embarked upon by the Government under the Agricultural Transformation Program. The Cassava Transformation seeks to create a new generation of cassava farmers oriented towards commercial production and farming as a business, and to link them up to reliable demand, either from processors or a guaranteed minimum price scheme of the government. The overarching strategy of the cassava transformation is to turn the cassava sector in Nigeria into a major player in local and international cassava value-added products by adopting improved production and processing technologies, and organizing producers and processors into efficient value-added chains.
The expected outputs in this effort for example, are starch, HQCF, sweeteners, dried chips, high quality gari, and fuel ethanol.
Value added Agriculture
Value-added agriculture refers most generally to manufacturing processes that increase the value of primary agricultural commodities. Value-added agriculture may also refer to increasing the economic value of a commodity through particular production processes, e.g. organic produce, or through originally-branded products that increase consumer appeal and willingness to pay a premium over similar but undifferentiated products. Apart from improving farmer's incomes, value addition has the ability to address the increasing level of unemployment in Nigeria.
Conceived from this perspective, the post-harvest systems of a country as they evolve from its primary agricultural production become the most powerful and strategic prime barometer or yardstick for measuring or determining if the desired agricultural change is taking place. They perform this function because value-added agricultural products emanate from primary processing within the farm-gate center, and progressing to secondary, tertiary and downstream levels, all within the domain of post-harvest technology.
Keeping this approach in mind, there are basically three ways in which value addition to farm produce can be achieved:
Level 1. Post-harvest level/primary processing:
Proper cleaning, grading and packaging e.g vegetables, potatoes, yams, fruits, tomatoes, etc.

Level 2. Secondary processing: basic processing, packaging and   branding e.g. packed rice, millet, maize, cowpeas etc.
Level 3. High end/downstream processing: supply chain management, modern processing technology, packaging of processed foods, branding, marketing e.g. potato chips, plantain chips, breakfast food, noodles, macaroni, etc.
All these levels will economically add value to a product and form characteristics more preferred in the market place.
Role of Value Addition in Transforming Nigerian Agriculture.
The roles of value addition within the context of Agricultural Transformation in Nigeria are multiple and catalytic. This is so because value addition embraces the range of technological questions that constitute the basis of the transformative operations of processing including importantly, a consideration of regenerative R&D that ensures that processing remains at all times competitive. Experience from around the world has shown that crop campaigns to raise productivity require a close partnership with research and development of enabling technologies.
In addition, and most importantly, value addition is at the critical milestone on the road to any meaningful transformation from primary agricultural production to agro-industrialization.
Value-addition accelerates the growth of economic development which is the process by which an economy is transformed from one that is dominantly rural and agricultural to one that is predominantly urban, industrial, and service-oriented in composition.
From Cassava alone, each of these values added products- starch, HQCF, sweeteners, dried chips, high quality gari, and fuel ethanol, is a harbinger of very strong industrial base.
With respect to wider industrial development of the country, value addition becomes an alternative production and marketing strategy that requires a better understanding of the rapidly changing food industry and food safety issues, consumer preference and effective agricultural management. There are various ways of adding value to a commodity and in a country like Nigeria, the scope of value addition is mind-boggling because of the availability of raw material and large market size. Six primary roles are important here:
Ø Value addition to agricultural produce reduces qualitative and quantitative losses of agricultural produce by bringing industrial processing nearer to the" sources of raw; material production.
Ø It augments foreign-exchange earnings by providing the basis for export of processed products and extractives rather than low-value raw materials and semi-processed products.
Ø Provides much-needed experience and training in the dispersal of industrial growth to backward and rural areas so as to generate new and enhanced employment opportunities.
Ø Creates enhanced opportunities for expanded spread of ownership of production units.
Ø Value addition stimulates the development of technological capabilities in terms of the capacity to engage in different scales of productive technologies in food processing.
Ø Fosters the development of engineering capabilities to design and manufacture food processing and ancillary machinery.
Clearly, these six elements continually interact and must be understood if any form of transformation in the agricultural sector is to begin.
Commodity Value-added Chain Activities in Nigerian Agriculture.
Since marketing of value-added products is more remunerative than raw commodities, farmer-processor linkages are needed to add value as per demands of the consumers. There is a great scope of developing some of our traditional food items from root and tuber crops, cereal grains and oil seeds, fruits and vegetables and flesh foods; and add value to them and form characteristics more preferred in quality and sensory attributes in the market place. Presented here (Table 1), is an attempt made to present sections of value added products to Nigerian agricultural produce, based on agricultural food resources of the country's ecosystems.

SUMMARY
Evidence from the field and beneficiaries' perceptions show that the NSPFS implementation has improved the productivity and sustainability of small holder agricultural systems with obvious improvement in beneficiaries' livelihoods, food security and socio-economic status. Strategies and approaches adopted in the implementation of the various activities under the Programme confirm the assertion that when productivity enhancing technologies and an efficient input delivery system are combined with dependable credit system and human capital development, farm productivity will improve, income will increase and farmers become empowered.
And in conclusion

I must state loud and clear that post-harvest systems encompassing primary processing within the farm-gate center and progressing to secondary, tertiary and downstream processing to add value and enhance market potential of agricultural produce are the critical prime movers of Food Security and agricultural change which in the present democratic dispensation in Nigeria dovetails nicely with the Transformation Agenda.

FUTO 2013 World Environment Day Welcome Address


WELCOME ADDRESS BY
DR. (MRS.) IHUOMA P. ASIABAKA,
AG. DIRECTOR CENTRE FOR WOMEN,
GENDER AND DEVELOPMENT STUDIES, CWGDS, FUTO,
ON THE OCCASION OF THE 201 3, WORLD ENVIRONMENT DAY CELEBRATION IN FUTO, HOLDING ON THURSDAY, 27TH JUNE, 2013.
PROTOCOLS
I feel highly delighted and honoured to welcome you all to the 2013 World Environment Day Celebration in FUTO. The World Environment Day was first celebrated in FUTO last year. The highlights of the 2012 celebration in FUTO were as follows:
ü Sanitary inspection of classrooms, student hostels, laboratories, workshops, cafeteria, toilet facilities and surroundings of all the buildings in the University.
ü Grassing of the environment for beautification and erosion control.
ü Tree planting for beautification/aesthetics, erosion control, wind breakers and environmental purification.
ü General environmental sanitation through grass-cutting, clearing of blocked gutters, sweeping etc.
ü Lectures, demonstrations and exhibitions on environmental issues.
CWGDS has decided to make the celebration of World Environment Day in FUTO an annual event to enable the University Community join the global conversation on environmental issues.
World Environment Day celebration aims at emphasizing the importance of protecting our planet and promoting an understanding that we can individually and collectively play significant roles in tackling environmental issues; especially considering the fact that the environment is intimately connected to global health. According to WHO report, environmental risk factors play vital role in more than 80% of diseases; and about 25% of the death can be attributed to the negative impact of the environment.
Through the celebration of World Environment Day, the United Nations (UN) personalized environmental issues enabling us to realize not only our responsibility, but also our power to become agents of change in support of sustainable and equitable development. The celebration draws attention to environmental challenges such as climate change, global warming, ecosystem management, resource efficiency etc. It also provides the platform on which the political, social, and economic problems of global environments are discussed at an intergovernmental forum with a view to actually taking corrective actions. It is celebrated annually on June 5th.
This year's Theme "Think-Eat-Save (TES) is chosen to encourage the prevention of food wastage and to raise awareness about the environmental impact of the food choices people make because when food is wasted, natural resources are wasted. TES also aims at reducing food loss along the entire chain of food production and consumption, particularly food wasted by consumers, retailers and hospitality industry.
It is an anti-food waste and food loss campaign that encourages us to re-assess our "food print" (food production). It is estimated that a third of food produced globally is either wasted or lost; and this is an enormous drain on natural resources and a contributor to negative environmental impacts. Global food production occupies a large area of habitable land, consumes about 70% of fresh water, accounts for 80% of deforestation and 30% greenhouse gas emissions thus resulting in loss of biodiversity and land-use change. When food is wasted, all the resources and inputs used in its productions are also lost.
According to United Nations Food and Agricultural Organization (FAO) 1.3 billion tonnes of food is wasted annually; and this is equivalent to the same amount of food produced in the whole Sub-Saharan Africa. United Nations Environment Programme (UNEP) reported that 1 in every 7 people in the world go to bed hungry and more them 20,000 children under the age of 5 die daily from hunger. Thus this enormous imbalance in life styles and the resultant devastating effects on the environment make this year's theme: "Think-Eat-Save" most timely.
It encourages us to become more aware of the environmental impact of the food choices we make and empowers us to make informed decisions about the food we eat so as to reduce the overall ecological impact.
This year we have articulated the following activities for the World Environment Day celebration in FUTO:
ü Sanitary inspection of Schools in FUTO to ascertain the cleanest School.
ü Environmental Sanitation
ü Students' Debate and Drama
ü Lectures
ü Slide Show
ü Prize-giving/Awards
It is hoped that at the end of 2013 World Environmental Day celebration in FUTO we will develop positive ways of protecting the environment through preventing food wastages by:
·        Sharing our excess food
·        Developing preference for local food
·        Using traditional preservation methods
·        Re-cycling of organic food
·        Conversion of organic waste into fertilizer
There is need for collective efforts at reducing food wastage, save money, minimize the environmental impacts of food production and make food production processes more efficient.
May I most sincerely appreciate in a very special way our beloved Vice-Chancellor, Prof. Chigozie C. Asiabaka KSM, JP and the University Management for approving and financially supporting this celebration. I also thank our Keynote speaker Prof. A.I. Ihekoronye for accepting to deliver the Keynote paper in a very short notice. I am grateful to the Deans, Directors, Managing Directors, Heads of Departments, Co-coordinators, the Unions and indeed the University Community for their unending love and support. To the Planning Committee led by Dr. (Mrs.) G.N. Okwu and our beloved students i say thank you for your efforts at ensuring the success of this celebration. Finally I thank all our distinguished guests from within and outside the State for honouring our invitation. Once more, I welcome you all to the 201 3 World Environment Day cerebration in FUTO
Thank you and God bless you.

2013 FUTO World Environment Day Address

AN ADDRESS BY PROFESSOR CHIGOZIE C. ASIABAKA, ksm, jp,

VICE-CHANCELLOR, FEDERAL UNIVERSITY OF TECHNOLOGY, OWERRI AT THE 201 3 WORLD ENVIRONMENT DAY CELEBRATION IN THE UNIVERSITY ON THURSDAY, JUNE 27, 2013
PROTOCOLS
I am delighted to welcome you all to this special event, the 2013 World Environment Day, holding in our University today under the auspices of our Centre for Women, Gender and Development Studies (CWG&DS).
Particularly, I welcome to our campus and acknowledge with profound gratitude the presence of our special guests at today's occasion. These include Barrister Emma Ekweremba, Honourable Commissioner for Petroleum and Environment, Imo State, Professor A. I. Ihekoronye, the Keynote Lecturer, a distinguished academic, an erudite scholar, a colleague and friend of inestimable value and Professor Emeritus of the University of Nigeria, Nsukka and Mr. A. Ebisike, the Registrar, Environmental Health Officers Registration Council of Nigeria, Abuja.
I recognize also the dignified presence of my Principal Officers, Deans, Directors, Heads of Departments/Units, Coordinators, Executives of Trade Unions on Campus, the President and Executive of Students Union Government, staff and students of our great University. Your unpretentious support, willing and sustained company have been immeasurable sources of inspiration and encouragement to me in my capacity as Chief Host of these unique events. I salute you all.
I thank, commend and congratulate the Director, Centre for Women, Gender and Development Studies, Dr Mrs Ihuoma P. Asiabaka and President, FUTO Women Association and her dedicated and resourceful team for mobilizing the University community to be part of this year's World Environment Day Celebration which commenced in earnest yesterday with sanitation exercise, clearing of the filth and the planting of flowers and ornamental trees within and around the University environment. Your faithful contributions towards the realization of our Quest for Excellence are enormous and most commendable. I urge you to keep up the good work.
Today's event is part of a global annual celebration instituted by the United Nations in 1 972. World Environment Day (WED) was promulgated as a special day to draw deserved attention to and create awareness on the environment which has much to do with the existence and survival of mankind on this planet earth. It is an indisputable fact that man's activities one way or the other affect the environment. The land we till for agriculture, the waste we dispose, the canals we build for irrigation, the drains we construct, the vehicles we drive on the roads, the industries and factories we establish, the petroleum products we exploit, the trees we fell, the animals we rear, the houses we build either for accommodation or for business, the boreholes we drill, the generators that provide us with power, and other innumerable activities of man impact positively or negatively on our cherished environment.
Indeed, the environment affects and influences all aspects of human life, physically, biologically, socially, mentally, spiritually and financially. Changes in the environment have far reaching implications and consequences on mankind, some beneficially and others detrimentally. This is why climate change which is now a global phenomenon is attracting much interest and huge investment from responsible governments across the globe to mitigate and address their unpleasant consequences.
The general impact and adverse effect of climate change on the environment, health, productivity and overall wellbeing of the world population are becoming grievous and unbearable. The problem leads amongst others to staple food shortages, economic decline, displacement and dislocation of human population, large scale migration, health hazards, loss of material resources and above all massive loss of precious lives.
Such vicissitudes of life could result from incidence of flood, draught, desert encroachment, earthquakes, landslides, and other disastrous climatic conditions that could be unleashed on humanity at little or no notice at all. This stark reality has made the theme of the 201 3 World Environment Day Celebration: Think-Eat-Save both apt and germane in our contemporary times. I have no doubt that our Guest Speaker has all it takes to dissect, drill and thrill us on this rather uncommon and unusual theme. Our guest I am sure has enough to dish out to this distinguished audience that at the end we will have more than enough to think about, eat and be able to save, especially for the uncertain rainy days. The lecture promises to advance good tips and create the necessary awareness on the vulnerability of the environment and how to mitigate some natural disasters arising from some environmental or climate change.
Emerging national and global reports precariously indicate that no nation, including ours, is immune or exempted from the devastating effects of changes in environmental conditions. Therefore, as a developing country, our best bet is to increase public awareness and knowledge on how to reduce possible circumstances that can pre-dispose our citizens to severe and disastrous environmental conditions. This is more so against the fact that our mechanism for disaster control/reduction and emergency preparedness appear, to all and intents and purposes, rudimentary in this part of the world.
Ours is a technological University with a school wholly dedicated to studies on environmental issues. It is therefore our due responsibility and mandate to create the needed fora and avenue such as this where important ideas and information could be generated on how best to handle issues that directly or indirectly affect our environment. In practical demonstration of our strategic role as champions on environmental matters, my administration considered it an aberration for the University to continue to operate in an unfriendly, hostile and life threatening environment surrounded by overgrown bushes that habour dangerous animals and reptiles.
This informed the decision of our administration to accord some priority to the creation of healthy environment through deliberate effort in the clearance of overgrown bushes, grassing of the lawns and pathways, opening up of the blocked drains, massive landscaping work on campus, repainting of buildings, planting and regular maintenance of flowers and ornamental trees, installation and improvement of lighting facilities throughout the University campus. All these measures, I am pleased to observe, are impacting wonderfully on our corporate drive for excellence in the University.

On this optimistic note, ladies and gentlemen, it is my honour and privilege to formally declare the 201 3 World Environment Day Celebration in our University open. Thank you and God bless us all.

World Environmental Health Day 2013

The date for World Environmental Health Day was chosen in 2010 by the International Federation of Environmental Health. The first day was commemorated in 2011 in Indonesia.
The theme of 2011 was ‘Air Quality’, 2012, ‘Building for the Future’ and for 2013 is ‘Emerging Environmental Health Risks and Challenges for Tomorrow’.
As an Environmental health practitioner, what do you think are the ‘emerging environmental health risks’ challenging Nigeria vis-à-vis world, and the ‘challenges for tomorrow’?

Global health: Issues, challenges, and management


Being a lead paper presented at the International Conference on 'Global health: issues, challenges and management, organised by Centre for Women, Gender,  and Development Studies; [CWGDS] and Institute of Environmental Health Technology, IEHT, Federal Univeersity of Technology, Owerri

Introduction
Global health has emerged as a growing field, particularly over the past two decades. Greater recognition of the global AIDS crisis, combined with the appearance and rapid international spread of epidemics such as SARS, anthrax, the Ebola virus, swine flu (H1N1), etc., have reinforced that health threats transcend national borders. While much of the media attention has focused on epidemic of infectious diseases, poverty, environmental pollution and degradation, social inequalities, global health looksat a wider scope of health problems, determinants, and solutions, such as chronic illnesses, accidents  and injuries. Other global health challenges include but not limited to poverty, environmental and health emergencies, gender violence and abuse, substance use and abuse, sex and sexuality, infant and maternal mortalities, terrorism etc.
Health was first defined in Preamble to the Constitution of the World Health Organization as adopted by the International Health Conference, New York, 19-22 June, 1946; signed on 22 July 1946 by the representatives of 61 States (Official Records of the World Health Organization, no. 2, p. 100) and entered into force on 7 April 1948; as “a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity. While there have been criticisms of this definition, the WHO has not changed its 1946 definition of health. More contentious, however, has been the definition of “global health.”
On the other hand, Public Health can be defined as the combination of sciences, skills, and beliefs that are directed to the maintenance and improvement of health of all people. The classic definition of public health describes it as  “the science and art of preventing disease, prolonging life, and promoting physical health and efficiency through organized community efforts for the sanitation of the environment, the control of community infections, the education of the individual in principles of personal hygiene, the organization of medical and nursing services for the early diagnosis and preventive treatment of disease, and the development of the social machinery which will ensure to every individual in the community a standard of living adequate for the maintenance of health”
Globally, the overall mission of public health is to "fulfil society's interest in assuring conditions in which people can be healthy." The three core public health functions are:
  •  assessing and monitoring  the health of communities and populations at risk to identify health problems and priorities;
  •  formulating public policies designed to solve identified local and national health problems and priorities;
  •  Assuring that all populations have access to appropriate and cost-effective care, including health promotion and disease prevention services, and evaluation of the effectiveness of that care.
Concept of Global Health
According to the Institute of Medicine, "Global health is the goal of improving health for all people in all nations by promoting wellness and eliminating avoidable diseases, disabilities, and deaths. Global health can be attained by combining clinical care at the level of the individual person with population-based measures to promote health and prevent disease. To achieve global health, an understanding of health determinants, practices, and solutions, as well as basic and applied research concerning risk factors, disease, and disability, is very important. Unlike Public Health, Global Health is more encompassing allowing the contributions of many other professionals in health issues and solutions.
Issues
Since 1950, global health has known quite a lot of improvements. However, this progress has not been equally distributed worldwide. A considerable number of countries primarily in Sub-Saharan Africa, especially Nigeria, lag behind the rest of the world on many health indices. For instance, health care systems are still neither available nor accessible (when and if available) to a great many people in Nigeria; infrastructural decay is common in the available health care systems; non-communicable diseases (such as cardiovascular diseases, cancer, diabetes and chronic lung diseases) are still major threats to Nigerians between the ages of 30 and above; hundreds of children under the age of 5 die from malnutrition, diarrhoea, measles, respiratory diseases and mostly preventable diseases, each year. It is on records that millions of people die of infectious diseases, such as HIV/AIDS, pneumonia, diarrhoea, tuberculosis and malaria annually. Other global issues include man-made and natural disasters (such as landslide; tsunamis; earthquakes; and flooding. The flooding of 2012 in Nigeria affected farming and sustenance of food availability in the nation, and displaced at least 10,000 people; etc.Furthermore terrorism, conflict, gender inequality, poor healthcare financing, emerging and re-emerging diseases, etc are other global health issues confronting Nigeria.
These health indicators continue to have a devastating impact on Nigeria and the world’s poorest countries. They make those countries vulnerable to social instability, economic breakdown, and decrease in population strength, spread of infectious diseases and increase in risk factors for chronic diseases.The vast range of global health issues are not without challenges.

Major Challenges

The biggest challenge in global health is the lack of financial resources to combat the multiple scourges ravaging the world's poor and sick. Today, more funds are needed for pressing heath issues than ever before. Furthermore, funds are needed to support research, build health facilities, train more health personnel, build capacity and competence among health care providers.
Tackling the world's diseases burden has become a key feature of many nations' foreign policies over the last five years, given that microbes know no borders. The focus of those nations is on keeping life expectancy high. That is another major challenge.For example,overall, 35% of Africa's children are now at higher risk of death than they were 10 years ago. Every hour, more than 500 African mothers lose a child. In 2002, more than four million African children died. Those who do make it past childhood are confronted with adult death rates that exceed those of 30 years ago. Life expectancy, that is always shorter here than almost anywhere else, is reducing still. In some African countries, it has been cut by 20 years and life expectancy for men is now less than 46 years.
A third major challenge is how to keep new health threats from emerging. While positive in many respects, urbanization, globalization, and demographic changes have intensified timeless health issues, changed the dynamics of health and resulted in the emergence of new health threats. Although HIV/AIDS, tuberculosis, and malaria are treatable and preventable diseases, meanwhile, many rich and poor countries alike have undergone an epidemiological transition in which non-communicable diseases – including depression, diabetes, cardiovascular disease, and cancers – have replaced infectious diseases as the leading causes of morbidity and mortality. Out of every 10 deaths worldwide, six are due to non-communicable conditions, three to communicable diseases, reproductive issues, or nutritional conditions, and one to injuries.
With increasing urbanization comes increasing violence and crime. In addition, the effects of depression and social exclusion can be more profound. About 14 per cent of the global burden of disease has been attributed to neuropsychiatric disorders, mostly owing to depression and other common mental disorders, alcohol- and substance-use disorders, and psychoses. The burden of major depression is expected to rise to be the second leading cause of loss of disability-adjusted life years in 2030 and will pose a major urban health challenge.
A fourth major challenge global health is confronted with is the manner in which to improve living conditions. Declining living conditions and reduced access to basic services have led to decreased health status. In Africa today, almost half of the population lacks access to safe water and adequate sanitation services. As immune systems have become weakened, the susceptibility of Africa’s people to infectious diseases has greatly increased. Global health initiatives aimed at improving the health and well-being of impoverished, vulnerable, and underserved people worldwide include poverty reduction strategies, disease prevention measures, efforts to improve nutrition and food security, policy to raise environmental standards and living conditions, and the promotion of gender equality.Health disparity between high-income and low-income countries, as well as between individuals within a country, often make this impossible, leaving many people living in unhealthy settings without sufficient access to care.
Management
For the world to begin to address health issues, three principles of action should be considered:
1.    Conditions of daily life have to be improved --- the conditions in which people are born, grow up, live, work and age;
2.    The inequitable distribution of power, money, and otherresources has to be tackled; the structural drivers of those conditions of daily life globally, nationally, and  locally;
3.    Problems have to be measured, actions evaluated, knowledge base expanded; a workforce that is trained in the social determinants of health has to be developed, and a public awareness has to be raised about the social determinants of health.
One framework for addressing global health challenges is the Millennium Development Goals (MDGs). The MDGs were adopted by the Member States of the United Nations in 2000 to achieve demonstrable reductions in poverty and improve specific health and social outcomes by 2015. The outlined goals reach beyond health issues, but four of the eight goals pertain directly to health:
  • Goal 1: Poverty Reduction
  • Goal 4: Reduce child mortality
  • Goal 5: Improve maternal health
  • Goal 6: Combat HIV/AIDS, malaria, and other diseases
The MDGs reflect widespread acknowledgement that improving global health is an integral part of development. However, the midpoint between 2000 and 2015 has passed, and the MDGs remain a distant goal for many countries especially Nigeria. For example, an estimated half-million women continue to die as a result of childbirth each year.  While substantial progress has been made in child health, the global community needs to intensify and sustain efforts in other areas in order to meet the MDG targets.
It is important to note that most health problems are caused not by health issues as such, but by social, political and economic conditions that drive people’s lives.
Conclusion
Poverty exacerbates health issues. Under conditions of poverty, entities such as pharmaceutical companies can wield even more power and influence over poor countries. Some major reasons for unnecessary deaths around the world are, therefore, due to human decisions and politics, not just natural outcomes. Well-intentioned companies, organizations and global action show that humanity and compassion still exists, but tackling systematic problems is paramount for effective universal healthcare that all are entitled to.
Addressing health problems goes beyond just medical treatments and policies; it goes to the heart of social, economic and political policies that provide not only for healthier lives, but also for a more productive and meaningful one that can benefit other areas of society.
The Federal Ministry of Health under President Goodluck Jonathan (GCFR) has in the last two years improved the infrastructure of our Health System for improved service delivery across the nation.
The Ministry is also currently involved in disease control and prevention through sustained routine immunization, health promotional activities, Environmental sanitation, safe motherhood.
In this respect the maternal and infant mortality rates are gradually going down, and hope that it will continue to improve.
This transformational agenda of President DrGoodluck Jonathan (GCFR) has also put in place various empowerment programmes to reduce poverty in Nigeria and this will continue until all global health indices are improved.
