Local Government and Traditional Authorities in Concert: Towards a More Productive Relationship

Ghana embarked on decentralisation in 1988 as a way of bringing decision making closer to the people. Since then, there have several reforms with a view to strengthening local governance. This article identifies a major challenge still facing Ghana’s decentralisation: Partnership between local government and traditional authorities. The paper discusses the fuzzy relationship between local governments and traditional authorities as a result of constitutional and legislative ambiguity on their relationship. Traditional Authorities perform important functions in the country, albeit their roles have waned since independence. Yet current legal provisions on local government have not sufficiently clarified their role in local administration. This has led to a murky and competing relationship between traditional authorities and local governments. In localities where mutual relationship exists, it is mainly as a result of the personalities involved and this has had a positive effect on the development of the area. The paper concludes by advocating for measures which among others include a re-enactment of legislation which will define the working relationship between traditional authorities and local government

La sélection de variétés résistantes à la maladie bleue du cotonnier dans l'Empire Centrafricain

La maladie bleue du cotonnier, vraisemblablement de nature virale, est transmise par le puceron Aphis gossypii Glover. Elle pose un sérieux problème économique en Centrafrique. Bien qu'il soit possible d'en diminuer l'incidence par l'emploi d'insecticides systémiques en désinfection des semences ou du sol, l'utilisation de variétés résistantes parait être la solution la plus efficace. Les auteurs donnent les résultats de trois années (1973-1975) d'observations sur différentes lignées et variétés d'origines diverses. Trois lignées sont résistantes à la maladie bleue : elles sont originaires de la station I.R.C.T. de Bouaké et issues du matériel triple hybride HAR (hirsutum X arboreum X raimondii), la résistance venant vraisemblablement de· Gossypium arboreum. Quatre lignées sont cotées comme tolérantes : l'une d'entre elles, SR 1-F 4, originaire de la station I.R.C.T. de Bebedjia, sera vulgarisée en Centrafrique à partir de 1977 à la place du BJA B 2. A plus long terme, la lignée HAR G-198/9/BJA2-1186 sur laquelle est entreprise une sélection massale pourrait être utilisée en culture

The Impact of Crop Rotation and Nutrient Levels on Nutrition Quality, Yield and Yield Components of Maize (Zea maize L)

Cropping system in crop production has many advantages and ensures better crop growth and yielding. Crop rotation methods can show optimal plants densities for maximal photosynthetic efficiencies and plant growth. This study aimed at investigating the effects of different crop rotation systems: monoculture and biculture rotations, and different nitrogen levels on yield, yield components and grain nutrient quality. The lowest Soil-Plant Analysis Development (SPAD), Leaf Area Index( LAI), Protein, plant height, cob length, and grain yield were found in monoculture plot signifying the influence of crop rotation on these measured variables. Nitrogen level at 120kg/ha had a significant effect on Protein, plant height and grain yield on the monoculture field whiles Moisture content, Protein content number of rows per cob and grain yield were also significantly affected at 120kg/ha level of nitrogen application on the biculture plo

Management, Control And Governance Of Hawala Networks In The Gulf Cooperation Council Region

Prior research has focused on the transactional aspects of the Hawala Networks (i.e. Invisible Funds Transfer Networks). However, little is known about the structure of this networked "organisation" especially about its governance and management control systems. Clanbased Organisations and Actor Network Theories were utilised to provide the theoretical base on which a research farmework was built. In total, 20 indepth interviews were conducted with Hawaldars (Hawala service providers) using a semi-structured questionnaire. As the study focused on the Gulf Cooperation Council region, data were collected from Qatar, UAE and Kuwait. The data indicated that there were no formal governance and management control systems in place for managing Hawala Networks (HNets); there were no explicit formal processes and mechanisms for evaluating performance and there was no formal performance measurement and tracking system in place to provide the information about network functionality. Results also showed that trust acted as the most important control mechanism impacting the efciency, effectiveness and the relatively lower transaction costs associated with HNets operation

Midazolam Efficacy Against Acute Hydrogen Sulfide-Induced Mortality and Neurotoxicity.

Hydrogen sulfide (H2S) is a colorless, highly neurotoxic gas. It is not only an occupational and environmental hazard but also of concern to the Department of Homeland Security for potential nefarious use. Acute high-dose H2S exposure causes death, while survivors may develop neurological sequelae. Currently, there is no suitable antidote for treatment of acute H2S-induced neurotoxicity. Midazolam (MDZ), an anti-convulsant drug recommended for treatment of nerve agent intoxications, could also be of value in treating acute H2S intoxication. In this study, we tested the hypothesis that MDZ is effective in preventing/treating acute H2S-induced neurotoxicity. This proof-of-concept study had two objectives: to determine whether MDZ prevents/reduces H2S-induced mortality and to test whether MDZ prevents H2S-induced neurological sequelae. MDZ (4 mg/kg) was administered IM in mice, 5 min pre-exposure to a high concentration of H2S at 1000 ppm or 12 min post-exposure to 1000 ppm H2S followed by 30 min of continuous exposure. A separate experiment tested whether MDZ pre-treatment prevented neurological sequelae. Endpoints monitored included assessment of clinical signs, mortality, behavioral changes, and brain histopathological changes. MDZ significantly reduced H2S-induced lethality, seizures, knockdown, and behavioral deficits (p < 0.01). MDZ also significantly prevented H2S-induced neurological sequelae, including weight loss, behavior deficits, neuroinflammation, and histopathologic lesions (p < 0.01). Overall, our findings show that MDZ is a promising drug for reducing H2S-induced acute mortality, neurotoxicity, and neurological sequelae

Capacity building on agricultural insurance for aggregators in Northern Ghana

Farming is a risky business. Shocks such as drought, flood, pests or disease can make it difficult for farmers to invest in new productive options, such as seeds or fertilizer. These shocks are often regional, reverberating past the level of the individual smallholder. This makes it equally difficult for aggregators such as seed companies, input providers, agri-shops, seed growers and for commercial farmers, all of whom rely on the yields of a large number of smallholders or out-growers. Agricultural insurance is one way to mitigate this risk, unlocking new markets and making existing markets more profitable Most training on insurance is either designed for poor smallholder farmers, or for very large aggregators (e.g. a country-wide fertilizer company). Less attention has been paid to small and medium level aggregators, who might have tens or hundreds of acres, or have a relationship with a smaller number of out growers (tens to thousands). However, connecting with these stakeholders is one method of scaling insurance in a sustainable fashion. The local nature of many of the aggregators allows insurance to reach smallholders without personally visiting every village. The aggregators are also typically from the local communities and can act as champions for new initiatives. These same incentives for connecting with aggregators also hold true for other CCAFS and rural development initiatives. The aim of this workshop was to reach a group of local aggregators in rural Ghana with tailored insurance capacity building material, detailed in this report. A secondary aim was to gather their feedback about their experiences with agricultural insurance, along with jointly designed ideas about how insurance could more easily fit in with their practices
