This exercise is part of the EU effort to strengthen Coordination & Harmonization in the follow up of the EU pilot Initiative on Coordination & Harmonization and a consequence of donor reporting requirements towards the Government of Mozambique, and in special the Departamento de Cooperação Internacional (DCI) and Departamento Nacional de Plano e Orçamento (DNPO) at the Ministry of Plan and Development (MPD). The data provided is based on the data provided by the Italian Cooperation in Mozambique. Completeness and exactness can only be guaranteed up to the 4th Quarter 2005 disbursement data. Forecast data is subject to own judgment of those reporting, and therefore might not always represent reality. The only sector codification allowed is the unique DAC/CRS sector classification which provides one five digit sector code per project, which should be the same in Headquarters and Field Offices. This will allow data from DbIS from different Donors to be compared nationally and internationally while at the same time providing a standard basis for analysis.

  • Shackled Orange: Biofortified Varieties in the Sweetpotato Commodity Chain in Mozambique
    Shackled orange: biofortified varieties in the sweetpotato commodity chain in Mozambique Roland Brouwer1 & Ilaria Tedesco2 Abstract Biofortified, orange-fleshed sweetpotato (OFSP) varieties are being promoted as a part of a strategy to reduce Vitamin A Deficiency among rural and urban populations in Sub-Saharan Africa. This paper uses the commodity chain approach to understand whether markets may stimulate or not the production of the new orange sweetpotato varieties on Mozambique’s main consumer market, Maputo, its capital and largest city. It shows that the chain linking rural producers to the city’s consumers is operated by private actors; the government provides basic infrastructures and price information. International donors are involved through the dissemination of planting material and nutrition information in support the marketing of OFSP. The commodity chains of white and orange-fleshed varieties are entwined with no clear price differences. The annual marketed volume is estimated at 8,000 tonnes, mostly produced by smallholders and sold to consumers by sidewalk and open-air market retailers. This market segment is dominated by women. A small group of specialized - male and female - commercial OFSP producers supplies about 0.5% to 1% of this market selling directly to a specific group of clients who either buy at farm gate or through home delivery. The conclusion is that the existing commodity chain fails to stimulate the production of OFSP and the expansion of its benefits to wider sections of the population suggesting that the emphasis should be on having biofortified varieties that can compete successfully with the conventional ones at the farm-level.

  • Disrespect and Abuse During Facility-Based Childbirth in Southern
    Galle et al. BMC Pregnancy and Childbirth (2019) 19:369 https://doi.org/10.1186/s12884-019-2532-z RESEARCH ARTICLE Open Access Disrespect and abuse during facility-based childbirth in southern Mozambique: a cross-sectional study Anna Galle1*, Helma Manaharlal2, Emidio Cumbane2, Joelma Picardo2, Sally Griffin2, Nafissa Osman2,3, Kristien Roelens1 and Olivier Degomme1 Abstract Background: Evidence suggests that many women experience mistreatment during childbirth in health facilities across the world, but the magnitude of the problem is unknown. The occurrence of disrespect and abuse (D&A) in maternity care services affects the overall quality of care and may undermine women’s trust in the health system. Studies about the occurrence of disrespect and abuse in Mozambican health facilities are scarce. The aim of this study was to explore the experience of women giving birth in hospital in different settings in Maputo City and Province, Mozambique. Methods: A cross sectional descriptive survey was conducted between April and June 2018 in the Central Hospital of Maputo (HCM) and district hospitals of Manhiça and Marracuene, Maputo Province, Mozambique. Five hundred seventy-two exit interviews were conducted with women leaving the hospital after delivery. The questionnaire consisted of the following components: socio-demographic characteristics, the occurrence of disrespect and abuse, male involvement during labor and childbirth and intrapartum family planning counselling and provision. Results: Prevalence of disrespect and abuse ranged from 24% in the central hospital to 80% in the district hospitals. The main types of D&A reported were lack of confidentiality/privacy, being left alone, being shouted at/scolded, and being given a treatment without permission.

  • Assessment of Factors Influencing the Adoption of Improved Crop Management Practices (Icmp) by Smallholder Farmers in the Boane District, Mozambique
    S. Afr. J. Agric. Ext. Da Encarnação Tomo Vol. 48 No. 1, 2020: 99 - 111 & Zwane http://dx.doi.org/10.17159/2413-3221/2020/v48n1a529 (License: CC BY 4.0) ASSESSMENT OF FACTORS INFLUENCING THE ADOPTION OF IMPROVED CROP MANAGEMENT PRACTICES (ICMP) BY SMALLHOLDER FARMERS IN THE BOANE DISTRICT, MOZAMBIQUE Da Encarnação Tomo, M.1 and Zwane, E.2 Correspondence author: E. Zwane. Email: [email protected] ABSTRACT This paper seeks to assess the factors influencing the adoption of the improved crop management practices (ICMP) in Boane District in Mozambique. The study was carried out using a qualitative survey method with a semi-structured interview schedule. Regression analysis and Pearson correlations were used to analyse the factors, constraints, and opportunities influencing the adoption of the improved crop management practices. The study covered a sample of 50 households. The results of the study show that the majority of the farmers (68%) in the Boane District adopted the improved crop management practices, compared to those who did not adopt them (32%). According to the logistic regression analysis, two factors (age and access to credit) were significant (p<0.05) at the 5% level of significance with the adoption of ICMP, meaning that age and access to credit have an influence on the adoption of the improved crop management practices in the Boane District. The study recommended that the Agricultural Development Fund and the district development should solve the challenge of low financial investments, which is the major problem of most smallholder farmers, limiting their response to the production process, and to adopting the improved crop management practices in the Boane District.

  • Assessment of Soil Loss to Vulnerability in the Boane District in Mozambique
    DOI: 10.14393/SN-v32-2020-46916 Received: 06 February 2019|Accepted: 06 February 2020 Assessment of soil loss to vulnerability in the Boane District in Mozambique Euclides Délio Matule1 Lucrêncio Silvestre Macarringue1,2 Keywords Abstract Boane The soil lost vulnerability study of the landscape units constitutes one of the Stability mechanisms for the design of sustainable land use and cover and natural Geoprocessing resources. Therefore, this research aimed to evaluate the soil loss vulnerability Soil Loss in the Boane district in 2018. The materials used included OLI Landsat 8 and ASTER GDTM V2 images, through which we generated land use and cover and slope maps respectively, soils, lithology, and precipitation databases available in CENACARTA. This data was processed in a GIS environment. The results showed that 53.3% of the district had median stability, 34.7% moderately vulnerable, 11.4% moderately stable, 0.6% stable and 0% vulnerable. These results indicate a favorable situation, but not comfortable at the short term, due to the accelerated rhythm of urbanization and its consequences to the environment that is seen in the last decades, joined to the lack or non- implementation of the main planning plans, that can change this situation in short term. 1Instituto de Formação em Administração de Terras e Cartografia, Matola, Moçambique.
