Abstract:
The aim of this study was to formulate an integrated wastewater management model for Harare, Zimbabwe, based on current thinking. This implies that wastewater is treated/disposed of as close to the source of generation as possible. Resource recovery and reuse in a local thriving urban agriculture are integrated into this model. Intervention strategies were considered for controlling water, nitrogen and phosphorus flows to the lake. In the formulation of strategies, Harare was divided into five major operational areas of high-, medium-, and low-density residential areas, and also commercial and industrial areas. Specific options were then considered to suit landuse, development constraints and socio-economic status for each area, within the overall criteria of limiting nutrient inflows into the downstream Lake Chivero. Flexible and differential solutions were developed in relation to built environment, population density, composition of users, ownership, future environmental demands, and technical, environmental, hygienic, social and organisational factors. Options considered include source control by the users (residents, industries, etc.), using various strategies like implementation of toilets with source separation, and natural methods of wastewater treatment. Other possible strategies are invoking better behaviour through fees and information, incentives for cleaner production, and user responsibility through education, legislative changes and stricter controls over industry.

Abstract:
Many Penicillium species found in soil provide vital ecosystem services such as turnover of organic matter and mineral weathering. Recently, some such species have been shown to increase the growth of plants, particularly on soils that bind phosphorus tightly. There is now interest in the exploitation of this group of Penicillium as a means to increase agricultural production. Could this be the next chapter in our exploitation of this genus?

ENGLISH ABSTRACT: Continuous cropping without replenishing the nutrient component of soils will eventually lead to the depletion of soil nutrients. Small scale farmers in Zimbabwe often do not have the financial means to buy fertilizer and this problem is exacerbated by scarcity of commodities such as fertilizers. The use of herbaceous legumes such as mucuna (Mucuna pruriens) can assist to recapitalize soil fertility depletion and improve subsequent maize productivity in sandy loam soils in the small holder farming sector of Zimbabwe. In this study the effect of phosphorus (P) application to a mucuna crop, the effect of mucuna management options and the application of nitrogen (N) to the subsequent maize crop was investigated. The experiment was carried out during the 2007 to 2009 seasons at the Grasslands Research Station in Marondera in Zimbabwe. The soils are classified as humic ferrolsols and are predominantly of the kaolinitic order with sandy loams of low fertility and are slightly acid (pH CaCl = 5.2). A randomized complete block design was used for the effect of P on mucuna productivity and the effect of P and mucuna management options on the soil properties. The treatments were two P rates (P0 and P40 = 0 kg P ha-1 and 40 kg P ha-1 respectively) applied to a preceding mucuna crop, four mucuna management options [1) fallow (F) (no mucuna planted = control), 2) mucuna ploughed-in at flowering (MF), 3) all mucuna above ground biomass removed at maturity and only roots were ploughed-in (MAR) and 4) mucuna pods removed and the residues ploughed-in (MPR)]. A split-plot design was used to study the effect of P application to mucuna, mucuna management options and N rates on the growth and yield of the subsequent maize crop. The four N treatments [N0 = 0 kg N ha-1, N40 = 40 kg N ha-1, N80 = 80 kg N ha-1 and iv N120 = 120 kg N ha-1] were applied to a subsequent maize crop. Growth and development parameters such as biomass production, leaf area index, nutrient content of the foliage and grain yield were determined in the mucuna and maize crops. Soil parameters investigated included nutrient content, pH, bulk density and porosity. Phosphorus application in these particular soil conditions positively influenced mucuna biomass production and therefore enhanced the role of mucuna as a rotational crop by increased positive effects on the subsequent maize crop. The incorporation of above-ground biomass of mucuna had positive effects on all soil properties investigated. The MF and MPR management options increased the soil organic matter (OM) and reduced bulk density which leads to an improvement in porosity (f) of the soil. Mucuna incorporated at flowering (MF) and P40 treatment combination resulted in the highest mineral N, P, potassium (K), calcium (Ca) and magnesium (Mg) levels. A significant three-way interaction (P<0.05) between mucuna management options, nitrogen rates and time was observed in terms of biomass production and all nutrients in the leaves of the subsequent maize crop. The main findings were that the MF management option had the highest biomass and foliar nutrient accumulation through-out all the treatment combinations. In general the MF management option gave the highest maize yield across all the treatment combinations. Incorporation of mucuna biomass into the soil prior to planting a maize crop therefore improve soil physical and chemical qualities resulting in improved soil conditions for a subsequent maize crop which in turn lead to higher maize yields. Including a mucuna rotational crop have a similar effect on maize yield than application of 80 kg ha-1 of fertilizer N.
AFRIKAANSE OPSOMMING: Aanhoudende verbouing van gewasse op dieselfde grond sonder om voedingstowwe aan te vul lei uiteindelik tot die agteruitgang van die grond se vrugbaarheid. Kleinboere in Zimbabwe het meestal nie die finansiële vermoëns om bemestingstowwe te koop nie en die probleem word vererger deur die onbekombaarheid van kommoditeite soos bemestingstowwe. Die gebruik van kruidagtige peulplant gewasse soos mucuna (Mucuna pruriens) kan bydra om grondverarming teen te werk en om die produksie van ‗n daaropvolgende mielie aanplanting in sandleemgronde in ‗n kleinboerstelsel in Zimbabwe te verhoog. In hierdie studie is die invloed van fosfor (P) toediening aan ‗n mucuna aanplanting, die invloed van bestuursopsies van die mucuna en die toediening van stikstof (N) aan die daaropvolgende mielie aanplanting ondersoek. Die eksperiment is tydens die 2007 tot 2009 reënseisoen by die Grasslands Research Station in Marondera in Zimbabwe uitgevoer. Die grond word geklassifiseer as humiese ferrolsols en is hoofsaaklik sanderige leemgrond van die kaolinitiese orde met lae vrugbaarheid en is effens suur (pH CaCl = 5.2). ‘n Volledig ewekansige blokontwerp is gebruik om die invloed van P op die produktiwiteit van mucuna te bepaal asook die invloed van P toediening en mucuna bestuursopsies op grondeienskappe. Die behandelings was twee P vlakke (P0 = 0 kg P ha-1 en P40 = 40 kg P ha-1) wat aan ‗n voorafgaande mucuna aanplanting toegedien is, vier mucuna bestuursopsies [1) braak (F) (geen mucuna geplant = kontrole), 2) mucuna ingeploeg met blomtyd (MF), 3) alle bogrondse mucuna biomassa verwyder by rypwording en slegs wortels ingewerk (MAR) en 4) mucuna peule verwyde en die res van die bogrondse material ingeploeg (MPR)] en vier N behandelings [N0 = 0 kg N ha-1, N40 = 40 kg N ha-1, N80 = 80 kg N ha-1 en N120 = 120 kg N ha-1] toegedien aan ‗n daaropvolgende mielie aanplanting. Groei en ontwikkeling parameters soos biomassa produksie, blaaroppervlakindeks, nutriëntinhoud van die blare en graanopbrengs is in die mucuna en mielie aanplantings ondersoek. Grondeienskappe soos nutriëntinhoud, pH, bulkdigtheid en porositeit is gemeet. Fosfaat toediening aan hierdie spesifieke grondtipe het mucuna produksie positief beïnvloed en dus die rol van mucuna as rotasiegewas verbeter deur positiewe reaksies in die daaropvolgende mielie aanplanting. Die inwerk van bogrondse mucuna biomassa het al die fisiese grondeienskappe wat ondersoek is positief beïnvloed. Die MF en MPR bestuursopsies het organiese materiaal inhoud van die grond verhoog en bulkdigtheid verlaag wat lei tot verbeterde grondporeusheid (f). Mucuna wat tydens blomvorming ingewerk is (MF) lei tot die hoogste minerale N, P, kalium (K), kalsium (Ca) en magnesium (Mg) vlakke. ‗n Betekenisvolle drie-rigting interaksie (P < 0.05) tussen mucuna bestuursopsies, N vlakke en tyd is waargeneem in terme van biomassa produksie en in terme van al die nutriëntvlakke in die mielieblare wat ondersoek is. Die hoofbevindinge was dat die MF bestuursopsie die hoogste biomassa produksie en blaarnutriënt akkumulasie oor alle behandelingskombinasies tot gevolg gehad het. In die algemeen het die MF bestuursopsie die hoogste mielie-opbrengs oor alle behandelingskombinasies tot gevolg gehad. Die inwerk van mucuna materiaal in die grond voordat mielies geplant word verbeter dus fisiese en chemiese toestande in die grond wat grondtoestande verbeter vir die daaropvolgende miegewas en uiteindelik lei tot hoër mielie-oeste. Die insluiting van mucuna as ‘n rotasiegewas het diesefde effek op mielie-opbrengs as die toediening van 80 kg ha-1 N bemesting.

Abstract:
The management of natural resources has greatly improved over the past decade. Despite advances in modelling the fate of nutrients or in modelling socio-economic effects of different farm management strategies, tools that integrate the advances made in these fields are still lacking. To develop a tool to overcome this gap, this research focused on the development of a multi-objective decision support system (MODSS) to alleviate phosphorus (P) contamination from agricultural fields and small watersheds. A decision supporting framework was designed to allow technical and public users to run the MODSS. The MODSS consists of the following elements: nonpoint source pollution models, an expert system to analyse the output of a qualitative P model, a scenario creation routine, a routine to estimate percentage and load based P reduction, a cost/benefits routine and a trade off analysis routine. Throughout the development of the MODSS, it was necessary to design a modified P Index for Southern Quebec. During the design process, the risk class 'controlled subsurface drainage' was introduced into the parameter subsurface drainage. The risk class was included due to findings that suggested that subsurface drainage is an important pathway for P loss in Southern Quebec. The modified P Index was coupled with a pre-screening routine to shorten the P Index analysis. The MODSS was applied to the Castor watershed, Quebec, Canada. The analysis showed that contributing distance, modified connectivity and P application rates are most likely probable causes for P movement from the fields in the Castor watershed. Additionally, the analysis showed that if BMP to reduce P loss are adopted the farmers could generate a surplus income.
La gestion des ressources naturelles s'est considérablement améliorée pendant la décennie passée. Malgré les avances dans la modélisation du destin des nutriants ou dans le domaine de modélisation des effets socio-économiques de différentes stratégies de gestion agricole, il nous manque toujours les outils d'intégrer les avances dans ces domaines. Afin de créer un outil d'integration de ces avances, cette recherche s'est concentrée sur le développement d'un système de soutien à la décision à objectifs multiples pour alléger la contamination de phosphore (P) à partir des champs agricoles et des petites lignes de partage. Le système inclut une interface de soutien à la décision permettant aux utilisateurs techniques et au grand public d'utiliser le MODSS. Le MODSS est composé des éléments suivants: plusieurs modèles de pollution diffuse, un système spécialisé pour analyser le produit de sortie d'un modèle de phosphore qualitatif, une routine de création de scénario, une routine pour estimer la réduction du phosphore en termes de pourcentage et de charge, une routine d'analyse avantages-coûts et une routine d'analyse d'échanges. Le développement du MODSS nécessitait la proposition d'un index du phosphore adapté au sud du Québec. Une nouvelle classe de risques a été introduite dans le paramètre de drainage souterrain: le drainage souterrain contrôlé. Cette classe de risques a été ajoutée, puisque des résultats de recherche extérieurs suggéraient que le drainage souterrain constitue une voie importante de perte du phosphore dans le sud du Québec. L'index modifié du phosphore a été couplé avec une routine d'examens préliminaires afin de raccourcir l'analyse. Le MODSS a été appliqué au bassin-versant de Castor au Québec, Canada. L'analyse a démontré les causes probables du mouvement de phosphore provenant des champs du bassin-versant de Castor : la distance par rapport au point d'origine, la connectivité$

Abstract:
A cardinal development goal of the Zimbabwean government is agricultural mechanization through the acquisition and use of tractors by arable crop farmers in communal and resettlement state land. This research project therefore aimed at investigating the impact of mechanization on agricultural productivity focusing on farmers in Bindura district of Zimbabwe who benefitted under the ongoing farm mechanization program. The existing land policy and the issue of technical efficiency in agricultural productivity are assumed to be the drivers of the program. It is likely that these key issues will constitute an important consideration in determining the sustainability of the mechanization policy. A multistage sampling technique was used to randomly select 90 farmers in the study area. The Cobb Douglas approach and Logistic regression were used to analyze data obtained from the respondents. Results revealed that tractor use was positively influenced by household size, access to extension services and crop output equivalent. Education, land area cultivated, stoniness negatively influenced the probability of adoption of mechanized farming. Furthermore, the technical efficiency estimate of adopter and nonadopters of mechanized farming showed no difference in their level of technical efficiency in agricultural productivity that was 64 percent on average. The level of observed inefficiency was increased by slope, stoniness and household size while age reduced technical inefficiency. It is recommended that government should consolidate the present gains arising from extension services. Also, environmental factors such as slope (topography) and stoniness, which constituted major disincentives in communal areas, could be overcome if government and farmers can identify and open up new areas of farmland for occupation by farmers.

Abstract:
Access to financial services from financial institutions has often proved to be one of the major constraints to rural and smallholder agricultural development in Zimbabwe. However, the ICT revolution across the world leading to the development of branchless banking options has brought new financial inclusion opportunities in the rural areas. The purpose of this study was to determine the role of branchless banking in smallholder agriculture through investigating the user patterns and adoption rate of mobile banking by rural farmers in Zimbabwe. Zvimba District was used as the case study while mobile banking was the branchless banking option investigated. The study also sought to investigate the barriers to adoption of mobile banking, in addition to laying out the difference between traditional banking channels and mobile banking. A survey through a structured interview with rural smallholder farmers was the main means of data collection. The data collected was then used to quantify the adoption of mobile banking, the barriers to adoption, and the alternative financial service providers used in rural areas, making it possible to draw conclusions for the purposes of policy formulation. The findings from the study revealed a high rate of adoption of mobile banking among the rural people. According to the study, even though mobile banking was cheaper and more accessible, traditional banking channels were still cited as being an important need for rural people. The significant factors investigated as creating barriers to adoption of mobile banking included age, education, income, marital status and farming experience, while factors such as gender and farm size proved to be insignificant. In light of the findings, it was recommended that besides transactional uses, branchless banking should be further developed and enhanced to provide other services such as insurance services and credit needed by smallholder farmers. Furthermore, in order to enhance customer uptake, mobile network operators (MNOs) were recommended to consider a segmentation approach when extending services to appropriate segments in rural areas.

Abstract:
The research sought to examine the effect of literacy on access to, and utilization of agricultural information for household food security at Chirau Communal lands in Zimbabwe. The study was influenced by the diffusion of innovations approach based on interviews, observation and document study. Selected female farmers from Chirau communal lands were respondents to the self administered interviews and focus group discussions. Representatives from, Agriculture Extension and the Ministry of Agriculture were key informants. Systematic Random sampling was used to select 100 female respondents from the age of 18 to above 80 from wards 1 to 10 of Chirau Rural District in Zimbabwe. Data was analyzed into themes and coded for statistical analysis using the SPSS. The country is faced with food insecurity and the main findings of this study support the view that women play an active role in food production but their potential is limited by inadequate levels of literacy that affect the way they access and utilize resources for sustainable agriculture and household food security among other factors. This may be generalized to the situation of female farmers in Zimbabwe. Improved literacy competencies among the female farmers in Zimbabwe lends itself as one of the interventions that may assist in improving access to information and its effective utilization.. This calls decision-makers to boost literacy for women, develop available agricultural information resources and harness effort towards making them accessible. While interventions may be multi-sectored, the role of government is stressed in this report.

Abstract:
Agricultural development is back on the development agenda. Even though the smallholder farmers are in the majority and at the forefront in terms of food production and agriculture being the backbone of the economy of Zimbabwe, there is no clearly defined policy on smallholder agriculture in Zimbabwe. The food insecurity has remained a continuous challenge for the rural poor in Zimbabwe. This study investigated the contribution of smallholder agriculture to food security with particular reference to the Masvingo province. The study employed qualitative method of research entailing extensive review of literature as a method of data collection. The study utilized the modernisation theory and sustainable livelihoods framework to illustrate smallholder agriculture and food security nexus. The study revealed that smallholder agriculture is the best option for addressing food security since agriculture is considered the main livelihood strategy for small scale farmers in Zimbabwe. There is general scholarly consensus that the main cause of food insecurity in Zimbabwe is a decrease in smallholder agriculture productivity. The study revealed that poor infrastructure , limited access to credit, limited access to inputs, poor investment in human development, limited access to markets and harsh climatic conditions weaken the capacity of small scale farmers to improve food security. Key recommendations are that supportive institutions need to be put in place to strengthen the smallholder farmer’s capacity to improve food security in Zimbabwe.

Abstract:
Zimbabwe has faced severe droughts, resulting in low agricultural outputs. This has threatened food and nutrition security in community sections, especially in areas with low annual rainfall. There is a growing need to maximize water usage, monitor the environment and nutrients, and temperatures by the adaptation of smart agriculture. This research explored the use of the Internet of Things (IoT) for smart agriculture in Zimbabwe to improve food production. The mixed methodology was used to gather data through interviews from 50 purposively sampled A2 farmers in the five agricultural regions of Zimbabwe and was supported by the use of the Internet. The findings reveal that some farmers have adopted IoT in Zimbabwe, others are still to adopt such technology and some are not aware of the technology. IoT’s benefits to Zimbabwean farmers are immense in that it improves food security, water preservation, and farm management. However, for most farmers to benefit from IoT, more awareness campaigns should be carried out and mobile and fixed Internet connectivity improved in some of the areas.

Abstract:
COVID-19 has undoubtedly affected lives and livelihoods across the globe. In Zimbabwe, preliminary indications point to a worsening economic situation in a country already facing macroeconomic challenges, particularly in rural communities where most households depend on agriculture. National lockdown and movement restrictions have affected agricultural activities as well as access to markets and farming inputs.
