Streamlining policies for enhancing rice production in Africa: Past experiences, lessons learnt and the way forward

There is a consensus that African development confronts several challenges, which include alleviating widespread poverty and unemployment, providing basic foods for the people, containing the HIV/AIDS pandemic, eliminating gender disparities and ensuring sustainable management of natural resources. In order to overcome theproblem of food supply, investment policies have focused on certain commodities. Rice (Oryza sativa) has been at the centre of particular policy attention in West Africa since the 1970s, following the formation of West Africa Rice Development Association (WARDA). Even though substantial investments and policy actions have been undertaken, the results belied the efforts made and expectations nursed. Africa today still depends on rice imports at a scale never imagined and domestic rice production programmes have been largely unsuccessful. The question is: What went wrong? Why has Africa been unable to produce enough rice to stem imports? Why did the initial investments in irrigation schemes and programmes fail? Now that attention is on expanding rice cultivation to other parts of Africa, what policy imperatives are essential to ensure sustainable rice production? This paper examines these issues by drawing experiences from several countries across West Africa. The overall objective is to provide appropriate policy framework for the expansion and sustainable production of rice to new areas in Africa. Specifically, the paper examines some of the policies pursued in the past in a number of countries and the reasons for their ineffectiveness. Drawing on the benefits of past experiences, the paper makes proposals forimproved policy environment to support the new initiatives to increase rice output in the continent

Electric field response of strongly correlated one-dimensional metals: a Bethe-Ansatz density functional theory study

We present a theoretical study on the response properties to an external electric field of strongly correlated one-dimensional metals. Our investigation is based on the recently developed Bethe-Ansatz local density approximation (BALDA) to the density functional theory formulation of the Hubbard model. This is capable of describing both Luttinger liquid and Mott-insulator correlations. The BALDA calculated values for the static linear polarizability are compared with those obtained by numerically accurate methods, such as exact (Lanczos) diagonalization and the density matrix renormalization group, over a broad range of parameters. In general BALDA linear polarizabilities are in good agreement with the exact results. The response of the exact exchange and correlation potential is found to point in the same direction of the perturbing potential. This is well reproduced by the BALDA approach, although the fine details depend on the specific parameterization for the local approximation. Finally we provide a numerical proof for the non-locality of the exact exchange and correlation functional.Comment: 8 pages and 8 figure

Seroprevalence and risk factors of Hepatitis C Virus in patients and blood donors in Kano, Nigeria

Hepatitis C virus (HCV) is a major cause of chronic liver disease resulting in cirrhosis and hepatocarcinoma. It is believed to be widespread in Africa but its epidemiology is incomplete and is yet to be determined in many areas of the sub-saharan Africa including Nigeria. Using third generation enzyme immuno-assay (EIA-3) and recombinant immunoblot assay (RIBA) technique as confirmatory test, we examined the prevalence of HCV antibodies in 226 blood donors and 226 patients attending Aminu Kano Teaching Hospital (AKTH) in Kano, Nigeria and evaluated the risk factors of HCV transmission in this environment. HCV antibodies were detected in 0.4% and 2.2% blood donors and patients respectively. The overall HCV seroprevalence was 1.3%. There was increased infection acquisition with increasing age; one (16.7%) HCV infection occurred in 25-34 years age group and 5 or 83.3% in subjects > 45 years in age which was significant (P< 0.05). The ratio of infection in male to female was 1:5. Evidence of previous exposure via transfusion was common in HCV seropositive subjects and could be a major risk factor of acquisition in this environment. Adequate screening of blood products in sub- Saharan Africa (Nigeria inclusive) may minimize the risk of HCV transmission and associated health complications.Key words: Hepatitis C virus, seroprevalence, patients, blood donors, risk factors

Antibiotics resistance of a strain of Escherichia coli isolated from bore hole in Ile Ife, Osun state, Nigeria

Abstract:Escherichia coli were isolated from water from two boreholes in Ile Ife, Osun state, Nigeria. This was an indication of faecal contamination. These strains of Escherichia coli were Gram negative short rods, Catalase positive, Methyl red positive, Voges Proskaeur negative. The strains could ferment glucose galactose, sucrose, lactose, mannitol and maltose with the production of acid and gas but could not hydrolyze starch. A particular strain was resistant to sulfamethoxazole, ampicillin, cotrimoxazole, cephaloridine, streptomycin, carbenicillin, sulfafurazole and tetracycline but sensitive to gentamicin, colistin, nalidixic acid, nitrofurantoin and colistin sulphat

THE NATURE OF E-GOVERNANCE IN PUBLIC SERVICE DELIVERY IN NIGERIA: A THEORETICAL EXPLORATION

The world has become a global village where every nation including Nigeria is striving to attain a high level of electronic governance implementation because of its capacity to bring about appreciable public service delivery. However, there has been so much confusion on the clarifications on what electronic governance is and public service delivery is about, let alone their nature in the public sector. It is to th is end that th is paper examines the nature of electronic governance in public service delivery in Nigeria. Data fo r this paper are obtained from literature review of the subject matter from texts, journal articles and the internet. While the analysis is done in themes. This paper finds out that the adoption and implementation rate of electronic governance in the public organisations are abysmal and thereby affecting the desired public service delivery. Based on these findings , this paper recommends among others that the public sector in Nigeria should endeavour to keep abreast of and embrace innovations which would aid in the speedy adoption and implementation of electronic governance that wi ll enhance public service delivery in Nigeri

ANALYSIS OF THE FACTORS AFFECTING CHANGE MANAGEMENT IN PUBLIC ORGANISATIONS IN NIGERIA

The hallmark of every working organisation the world over, has been the change in how employees are being managed and how services are being delivered to the public since all managers are interested in improving upon the successes of yesterday as well as meeting up with the everyday changing environment. However, with in the context of public organisations in Nigeria, change management has been challenged by a number of factors internally and externally that have come to make such processes difficult if not impossible. This paper analyses the reasons for the difficulties experienced by employees of public organisations in Nigeria with regards to the change process and also proffers strategies on how to overcome the challenges associated with change management in order to achieve employees' commitment and loyalty while improving the way and manner which services are being delivered to the people

Water Pollution: Effects, Prevention, and Climatic Impact

The stress on our water environment as a result of increased industrialization, which aids urbanization, is becoming very high thus reducing the availability of clean water. Polluted water is of great concern to the aquatic organism, plants, humans, and climate and indeed alters the ecosystem. The preservation of our water environment, which is embedded in sustainable development, must be well driven by all sectors. While effective wastewater treatment has the tendency of salvaging the water environment, integration of environmental policies into the actor firms core objectives coupled with continuous periodical enlightenment on the present and future consequences of environmental/water pollution will greatly assist in conserving the water environment
