Effects of conservation farming in Zimbabwe: the case of Umguza District in the post 2000 land reform programmeChipfakacha, Raymond Arthur 09 1900 (has links)
Text in English / The study analysed the effects of conservation farming in Zimbabwe using a mixed methodology approach. This analysis comes against the background of the recognition that climate change, as characterized by severe droughts, has played a significant role in reducing agricultural productivity, in the process leaving smallholder farmers and the nation of Zimbabwe exposed to recurrent food insecurity. Conservation farming was introduced as a climate adaptation strategy that was aimed at improving crop yields. The study focused on assessing the association between the adoption of conservation farming and a concomitant increase in agricultural productivity. This was key in understanding if there are benefits of using conservation farming as opposed to making use of the conventional method of farming. The study also investigated the nature of conservation farming being practiced in Umguza District; this was done in order to understand whether smallholder farmers are implementing all the key principles underpinning the use of conservation farming. The study further assessed the challenges and opportunities that exist through the use of conservation farming with the aim of coming up with sustainable solutions to the challenges affecting smallholder farmers. The study went on to assess the factors that determine the adoption and maximum utilization of conservation farming. Identification of these key variables was instrumental in the design of a localized conservation farming model. Study results revealed that conservation farming is an effective method of increasing agricultural productivity. The study also established that smallholder farmers are not implementing all the key principles of conservation farming and this was attributed to the failure to include the smallholder farmers in the design of conservation farming models. It was further revealed that smallholder farmers face various challenges that include access to inputs and limited support from the government. Implications of the study highlight the need for the community to be actively involved in the design of a conservation farming model localized to the unique context of smallholder farmers. A prototype for implementing a sustainable conservation farming model was developed in collaboration with the smallholder farmers as part of a solution based approach to dealing with the challenges affecting smallholder farmers. / School of Agriculture and Life Sciences / Ph.

Farmers' collective action and agricultural transformation in EthiopiaEtenesh Bekele Asfaw 08 1900 (has links)
Rural Ethiopia rolled-out a program for the establishment of farmers’ collective action groups known as ‘Farmers’ Development Groups’ (FDGs), in 2007, based on presumed common interest of smallholder farmers. Although the government trusts that FDGs fetch fast and widescale agricultural transformation as part of the participatory agricultural extension system, systematic study and evidence on what motivates smallholder farmers to act collectively, the group dynamics, long term impact and transformative potential of the agricultural extension groups is scarce.
Using the expectancy-value theory in social-psychology, this study explores what drives smallholders to act collectively; their participation level and benefits in groups, particularly for women and the youth; and the extent to which farmers’ groups attain intended agricultural transformation goals of productivity and commercialization. The study collected a mix of qualitative and quantitative data in 2016, through 46 key informant interviews; 8 focus group discussions with farmers, and a survey of randomly selected 120 smallholder farmers (30 percent women) in four sample woredas (districts) of Ethiopia. The findings of the study are drawn through a content analysis, and descriptive and correlation analysis of the qualitative and quantitative data, respectively.
The study findings show that social identity, and not ‘common interest’ motivates smallholder farmers to join and participate in FDGs. The study provides evidence that participation in FDGs enhances smallholder farmers’ adoption and use of agricultural technologies, where 96 and 84 percent of the farmers who received extension messages in the group on crop and livestock production, respectively, applied the message. Consequently, by 2015 more than 85 percent of the survey respondent farmers reported above 10 percent increase in crop and livestock productivity.
Nevertheless, the nature of the incremental changes brought by the collective actions are not transformative, nor sustainable. Extension groups have limited contribution to commercialization of smallholders, where only 20 percent of the FDG members participate in output marketing. More so, FDGs avail limited collective opportunity for the landless youth, and married female farmers in a rural society where difference in power, status and privilege prevail. It also limits deviation of thought among the rural community.
Limited access to inputs and technology; large family size; limited access to farm land; over dependence of the extension system on ‘model’ farmers and public extension agents, and poorly designed sustainability features bound the transformative potential of FDGs.
The study forwards a set of five recommendations to unleash the potential of FDGs: reconsider the group design to be identity congruent; ensure inclusiveness for young and female farmers; empower and motivate voluntary group leaders; encourage collective marketing and; invest in sustainability features of the group. / Development Studies / Ph.

ESSAYS ON AGRICULTURE AND FOOD SAFETY IN SUB-SAHARAN AFRICAYurani Arias Granada (13024980) 10 July 2022 (has links)
<p> </p>
<p>Food systems are facing unprecedented challenges and need reforms to be more efficient and provide safe and nutritious food from farm to fork. In this dissertation, I present new empirical evidence on different strategies to tackle two critical problems of food systems in sub-Saharan Africa (SSA): food contamination and the inefficient delivery and use of subsidized agricultural inputs. The first essay measures demand and network effects for a newly available technology called Aflasafe that delivers credence attributes (i.e., benefits difficult or impossible to observe and measure even after frequent use of the technology). The second essay exploits a policy change in Malawi to estimate the efficiency of public and private channels at distributing inputs to smallholder farmers. I use a panel dataset covering the period from 2010 to 2016 and a difference-in-differences (DID) framework to estimate the impact of the policy change on procurement of subsidized fertilizer, efficiency and service quality, agricultural productivity, and the household’s decision to purchase commercial fertilizer. The third essay identifies a series of constraints faced by smallholder farmers in Senegal and assesses which ones are associated with chemical and microbial contaminants in groundnut (peanut).</p>

A model for the adoption and acceptance of mobile farming platforms (MFPs) by smallholder farmers in ZimbabweMasimba, Fine 01 1900 (has links)
D. Tech. (Department of Information and Communication Technology, Faculty of Applied and Computer Sciences), Vaal University of Technology. / The agriculture sector is the lifeblood of the economies of the world's least developed countries (LDCs). In Zimbabwe, this sector is considered to be the backbone of Zimbabwe's economy, and as a result, it is the sector that supports the economic growth of the country, food security, and poverty eradication efforts. Furthermore, the use of mobile technology has continued to rise in Zimbabwe, and farmers now can obtain agricultural information through the use of mobile technology. Mobile phones are increasingly being integrated into current agricultural trade businesses, owing to the critical role they serve in facilitating information transmission between farmers and buyers. The potential of mobile phones in agriculture spawned mAgriculture, which is the use of mobile phones to provide agricultural information and services. Variousitechnology companies in iZimbabwe have come up with various mobile farming platforms as innovation, with the aim of improving overall performance among smallholder farmers. In order to find the usefullness of these mobile farming platforms, it imperative to measure the adoption and acceptance of this technology in the farming environment.
The study sought to investigate the adoption and acceptance of mobile farming platforms in Zimbabwe through a more comprehensive model based on UTAUT 2 that encapsulates the key factors that influence user adoption and acceptance of mobile farming platforms. The main aim of the study was to inform technology start-up companies and other mobile application developers in the development of mobile farming platforms or applications that can be fully adopted and accepted by users, taking into cognisance all salient factors affecting their adoption and acceptance. The model has been used to investigate smallholder farmers in a developing country such as Zimbabwe. The model explores the effect of attitude as one of the key determinants that affect the behavioral intention to use mobile farming platforms. In addition, the model looked at the moderating effect of Hofstede's five cultural dimensions on the key determinants that influence behavioral intention as well as actual use of mobile farming platforms at individual level.
A total of 411 questionnaires were received from smallholder farmers in Zimbabwe's three major provinces who were using mobile farming platforms. Structural Equation Modelling was utilized to test the hypothesized conceptual model. Reliability and validity checks were done to the model instrument. As hypothesized, the findings of this study revealed that performance expectancy (PE), effort expectancy (EE) and facilitating conditions (FC) are significant determinants of the newly added variable Attitude (AT). Attitude (AT), together with social influence (SI), facilitating conditions (FC), hedonic motivation (HM), price value (PV), and habit (HB) were found to be significant determinants of behavioral intention and usage of mobile farming platforms for smallholder farmers. The results also showed that cultural dimensions have a moderating effect on user acceptance of mobile farming platforms. According to the findings, attitude and culture are significant factors to consider when analyzing farmers' behavioral intentions and use of mobile farming platforms. The findings of the study contribute to the literature by validating and supporting the applicability of the extended UTAUT 2 for the adoption and acceptance of mobile farming platforms by smallholder farmers in developing countries. The theoretical contribution of the study was through the extension of UTAUT 2 where attitude was added as one of the new key determinants of behavioral intention and cultural dimensions were added as mediators. The other contribution is to the Zimbabwean farming community where the study was conducted.

Hydro-climatic Risk Assessment and Communication for Smallholder Farmers in Maharashtra / Bedömning och kommunikation av hydroklimatiska risker för småskaliga jordbrukare i MaharashtraEkström, Elin, Halonen, Jonna January 2021 (has links)
Smallholder farmers often have great entrepreneurial qualities that build on generations of experience. However, many farm management practices are poorly adapted to current climate change conditions. In order for farmers to understand the risks they are undertaking by following certain farming practices and to adapt accordingly, a decision support tool is being developed by researchers at TU Delft. The tool runs a socio-hydrological model, created in Python, in the back-end and provides farmer specific investment and profit data for different crops in the front-end. The aim of this study is to develop a risk assessment process that integrates hydro-climatic variability in the decision support tool, and to identify ways of communicating risk to smallholder farmers in Maharashtra, India. Two sources of variability were characterised based on a literature review of Indian farmers’ own risk perceptions; the untimely onset of the Indian Summer Monsoon and the frequency of dry spells. A sensitivity analysis was then carried out to investigate their respective effects on the farmers’ crop yields. The method proposed to evaluate these risks used a single variable, precipitation data, and a two-dimensional risk matrix to compound the two risk factors, over a time span of 14 years (2003-2016). However, the results indicate that it might be more beneficial to define dry spells in terms of crop water stress, instead of a precipitation threshold. This study also proposed a method for translating a cumulative distribution curve into a risk representation that is adapted for low-literacy users by combining numbers and text with graphics, color and voice descriptions. Ultimately, however, the usability of the tool cannot be determined solely through literature, but must involve the end-users in its design. / Småskaliga jordbrukare är goda entreprenörer som samlat på sig kunskaper och erfarenheter över flera generationer. Däremot är vissa metoder som jordbrukarna använder sig av idag för att förvalta sitt jordbruk inte anpassade till nutida klimatförändringar. För att jordbrukarna ska förstå riskerna som de åtar sig vid valet av dessa metoder försöker forskare vid TU Delft nu ta fram ett verktyg för att underlätta jordbrukares förmåga att ta självständiga men välgrundade beslut om sitt jordbruk. Verktyget är baserat på en socio-hydrologisk modell som är framtagen i Python och som förser specifika investerings- och inkomstdata för enskilda jordbrukare. Syftet med detta kandidatarbete är att bidra till verktyget genom att undersöka de hydroklimatiska risker som uppstår till följd av föränderliga och osäkra klimatologiska förhållanden för jordbrukare i delstaten Maharashtra, Indien. Två riskfaktorer karakteriserades baserat på en litteraturstudie om indiska jordbrukares riskuppfattningar: avvikelser i starten på den indiska sommarmonsunen och antal torrperioder under monsunsäsongen. Dessutom utfördes en känslighetsanalys för att undersöka om och hur den existerande modellens utdata av skörd påverkades av de valda riskfaktorerna. Monsunstarten och torrperioderna togs fram genom metoder som enbart använde historiska nederbördsdata över tidsperioden 2003-2016 och kombinerades sedan med hjälp av en tvådimensionell riskmatris. Resultaten visade att det fanns anledning att ifrågasätta hur torrperioderna definierades och att det kan vara mer fördelaktigt att undersöka vattenbrist för grödan, snarare än att enbart förlita sig på nederbördsdata. Vidare föreslog denna studie en metod för att översätta en kumulativ fördelningsfunktion till en grafisk riskframställning som är anpassad till användare med låg läskunnighet genom att kombinera siffror med text, grafik, färg och ljudförklaringar. I slutändan kan dock inte användbarheten av verktyget enbart avgöras utifrån litteratur, utan måste även inkludera återkoppling från slutanvändarna.

Determinants of rural household food security in drought-prone areas of Ethiopia : case study in Lay Gaint District, Amhara RegionBerlie, Arega Bazezew 11 1900 (has links)
This study examines rural household food security and its determinants in drought-prone Amhara Region of Ethiopia by focusing on Lay Gaint district as a case study site. A range of factors from physical environmental circumstances to policy and institutions-related issues determine households‟ vulnerability to food insecurity and livelihood outcomes. The survey results showed that the majority (74%) of the sampled households experienced food insecurity. The situation was worse among female-headed households such that 86% of them were food insecure. The study revealed that, despite the low level of productivity related to local environmental constraints, rural livelihoods remain undiversified with small scale rain-fed agriculture to provide the primary source of livelihood for the large majority of households (~93% of respondents). Only about 25% of the respondents participated in some form of non-farm or off-farm activities, but with only little contribution to their total annual incomes. Food insecurity is a chronic problem in that, on average, households in the study area consume from own production for only about six months. The study found out that the majority of households (about 80%) perceived annual rainfall to be inadequate to support the growing of crops and grazing of animals. The main adaptive strategies employed by the majority of households included diversifying livestock kept, planting trees and diversifying crops. The study revealed that incidence, depth and severity of food insecurity of the food insecure households showed that Woina-Dega and Kolla agro-ecologies are prone to vulnerability to food insecurity. This suggests that development interventions that are geographically differentiated; and build household assets will improve household food security in the study area, and in other similar environments in the country. / Geography / D.Phil.

Empowering Smallholder Farmers to Achieve Food Sovereignty Through Soil-Less AgricultureBalasubramanya, Abhijith Nag, Shaafiu, Fathimath Zainy January 2022 (has links)
This study explores the question of how soil-less agriculture through hydroponics, aeroponics, and aquaponics can empower smallholder farmers to achieve food sovereignty as portrayed in documentaries. It addresses the power imbalance between large corporations and smallholder farmers in the traditional agriculture industry. Documentary research approach is used to understand the various applications and research aspects of soil-less agriculture from around the world. Real-life examples from different countries where these methods have been successfully implemented in the agriculture industry, ranging from large industrial settings to smallholder farmers in disadvantaged communities, are analyzed. Further, content analysis is done on these documents by constructing a matrix that combines the process of empowerment and the six pillars of food sovereignty to analyze the different forms of empowerment. The study also investigates how the use of soil-less agriculture can build capabilities through enhanced “well-being freedom” and “agency freedom” and empower smallholder farmers to achieve food sovereignty.

Vulnerabilidad y capacidad adaptativa de la agricultura a pequeña escala en América Central: brechas actuales y elementos para la gestión de información de sequías y otros fenómenos del cambio y variabilidad climáticaBouroncle Seoane, Claudia María 13 November 2023 (has links)
Tesis por compendio / [ES] La agricultura a pequeña escala en América Central, región donde se esperan fuertes cambios en las temperaturas y patrones de lluvias, sostiene el empleo y la seguridad alimentaria de las familias rurales. La adaptación al cambio climático es, por ende, altamente prioritaria. Esta investigación analiza la vulnerabilidad al cambio climático y la capacidad adaptativa de los medios de vida agrícolas a pequeña escala en la región en dos niveles. El primer análisis usa información pública de municipios de cuatro países, mientras el segundo se basa en procesos participativos en cinco microcuencas de la vertiente del Pacífico. Esta investigación incluye también una evaluación de productos de información agroclimática para gestionar los impactos del cambio climático en la producción agrícola y la seguridad alimentaria en Guatemala.
El primer análisis muestra, en primer lugar, que los municipios que están en zonas de frontera agrícola o propensas a la sequía tienden a tener menor capacidad adaptativa, en contraste con la capacidad adaptativa más alta de los que están cerca a zonas urbanas y rutas de comercio. En segundo lugar, muestra que los grupos de municipios con menos satisfacción de necesidades básicas tendieron también a tener menor desempeño en los indicadores de acceso a la innovación y su puesta en práctica. Por último, muestra que los grupos de municipios que más incentivos agrícolas han recibido no tienen necesariamente una mayor capacidad adaptativa. Los resultados sugieren que los proyectos y programas de adaptación al cambio climático en la región deben considerarse un espectro de estrategias, y que la metodología propuesta puede apoyar el establecimiento de prioridades geográficas y la identificación de estas estrategias. El segundo análisis muestra diferencias fundamentales entre diferentes medios de vida agrícolas, en especial en su capacidad adaptativa. Los capitales humano y social mostraron amplias diferencias entre medios de vida que tienen acceso a la tierra y el agua, y los que dependen del arriendo de la tierra y de la venta de mano de obra. Aunque en todos los sitios hay algún nivel de incentivos y asistencia técnica, estas ayudas no necesariamente responden a las necesidades de adaptación de las familias agricultoras. Las medidas de adaptación implementadas y propuestas incluyen medidas incrementales y transformacionales, y existe conciencia en las familias agricultoras de la importancia de fortalecer los capitales no físicos para la viabilidad y sostenibilidad de las medidas de adaptación, y no solo el capital natural y construido. Estos resultados confirman que los programas de adaptación deben considerar un espectro amplio de estrategias y las necesidades a nivel local para una mejor inversión de recursos. La evaluación de productos de información agroclimática muestra progresos en la gestión de la variabilidad del clima en Guatemala, pero también que los productos destinados a apoyar decisiones para gestión de la agricultura y la seguridad alimentaria a nivel local requieren cambios en las prácticas institucionales de compartir y producir información más útil y oportuna.
Esta tesis intenta poner en valor diferentes fuentes de información y conocimiento para la adaptación al cambio climático, en una región donde es frecuente que se atribuya la falta de decisiones oportunas y objetivas a su ausencia y baja calidad. Las propuestas metodológicas tratan de identificar opciones para el mejor uso de los recursos disponibles y esfuerzos para apoyar la adaptación de la agricultura a pequeña escala en América Central. / [CA] L'agricultura a petita escala a Amèrica Central, una regió on s'esperen canvis bruscos de les temperatures i dels patrons de pluges, sosté l'ocupació i la seguretat alimentària de les famílies rurals. L'adaptació al canvi climàtic és, per tant, altament prioritària. Aquesta investigació analitza la vulnerabilitat front al canvi climàtic i la capacitat adaptativa dels mitjans de vida agrícoles a petita escala de la regió en dos nivells. La primera anàlisi usa informació pública de municipis de quatre països, mentre que la segona es basa en processos participatius en cinc microconques del vessant del Pacífic. Així mateix, aquesta investigació inclou una avaluació de productes d'informació agroclimàtica per tal de gestionar els impactes del canvi climàtic sobre la producció agrícola i la seguretat alimentària a Guatemala.
La primera anàlisi mostra, en primer lloc, que els municipis de les zones de frontera agrícola o propenses a la sequera tendeixen a tindre menor capacitat adaptativa, tot contrastant amb la capacitat adaptativa més elevada d'aquells municipis que són a prop de zones urbanes i de rutes comercials. En segon lloc, trobem que els grups de municipis amb menys satisfacció de necessitats bàsiques van tendir també a obtenir resultats inferiors en els indicadors d'accés a la innovació i la seua aplicació. Per últim, observem que els grups de municipis que han rebut més incentius agrícoles no tenen necessàriament una major capacitat adaptativa. Els resultats suggereixen que els projectes i els programes d'adaptació al canvi climàtic a la regió han de considerar tot un espectre d'estratègies, i que la metodologia proposada pot donar suport a l'establiment de prioritats geogràfiques i la identificació d'aquestes estratègies. La segona anàlisi mostra diferències fonamentals entre diferents mitjans de vida agrícoles, sobretot pel que fa a la seua capacitat adaptativa. Els capitals humà i social van mostrar àmplies diferències, d'una banda, entre els mitjans de vida que tenen accés a la terra i a l'aigua i, de l'altra, aquells que depenen de l'arrendament de la terra i de la venda de mà d'obra. Malgrat que a tot arreu existeix algun nivell d'incentius i assistència tècnica, aquestes ajudes no responen necessàriament a les necessitats d'adaptació de les famílies agrícoles. Les mesures d'adaptació implementades i proposades inclouen mesures incrementals i transformacionals, i les famílies agrícoles són conscients de la importància d'enfortir els capitals no físics de cara a la viabilitat i la sostenibilitat de les mesures d'adaptació, i no sols el capital natural i construït. Aquests resultats confirmen que els programes d'adaptació han de considerar un espectre ampli d'estratègies d'adaptació i les necessitats en l'àmbit local, per tal d'aconseguir una millor inversió dels recursos. L'avaluació de productes d'informació agroclimàtica mostra progressos en la gestió de la variabilitat del clima a Guatemala, però també que els productes destinats a donar suport a decisions per a la gestió de l'agricultura i la seguretat alimentària en l'àmbit local requereixen canvis en les pràctiques institucionals a l'hora de compartir i de transferir informació més útil i oportuna.
Aquesta tesi intenta posar en valor diferents fonts d'informació i de coneixement que faciliten l'adaptació al canvi climàtic, en una regió on és freqüent que s'atribuïsca la falta de decisions oportunes i objectives a la seua absència o baixa qualitat de les mateixes. Les propostes tracten d'identificar opcions que permeten millorar l'ús dels recursos disponibles i dels esforços per tal de donar suport a l'adaptació de l'agricultura a petita escala a Amèrica Central. / [EN] Smallholder agriculture in Central America, a region where marked changes in temperature and rainfall patterns are expected, sustains employment and food security for rural households. Adaptation to climate change is therefore a high priority. This research analyses the vulnerability to climate change and the adaptive capacity of small-scale agricultural livelihoods in the region at two levels. The first analysis uses public information from municipalities in four countries, while the second is based on participatory processes in five micro-watersheds on the Pacific slope. This research also includes the evaluation of agro-climatic information products that are intended to support the management of the impacts of climate change on agricultural production and food security in Guatemala.
The first analysis shows, first, that municipalities that are in agricultural frontier or drought-prone areas tend to have lower adaptive capacity, in contrast to those that are close to urban areas and trade routes. Secondly, it shows that groups of municipalities with less satisfaction of basic needs also tended to perform less well on indicators of access to and implementation of innovation. Finally, it shows that groups of municipalities that have received more state agricultural incentives do not necessarily have higher adaptive capacity. The results suggest that climate change adaptation programs and projects in the region should consider a spectrum of adaptation strategies, and that the proposed methodology could support the geographic prioritisation and identification of these strategies. The second analysis showed fundamental differences between different agricultural livelihoods, especially in their adaptive capacity. Human and social capitals showed wide differences between livelihoods that have access to land and water, and those that rely on renting land and selling labour. While there was some level of incentives and technical assistance in all sites, there were also differences in access to this support, which do not necessarily respond to the adaptation needs of farming families. The adaptation measures implemented and proposed include incremental and transformational measures, and there is awareness among farming families of the importance of strengthening non-physical capital for the viability and sustainability of adaptation measures, and not only natural and built capital. These results confirm that adaptation programmes should consider a broad spectrum of adaptation strategies and needs at the local level for better investment of resources. The evaluation of agroclimatic information products shows progress in managing climate variability in Guatemala, but also that products aimed at supporting decisions for agriculture and food security management at the local level require changes in institutional practices to share and produce more useful information.
This thesis attempts to highlight different sources of information and knowledge for climate change adaptation in a region where the lack of timely and objective decisions is often attributed to their absence or low quality. The methodological proposals seek to identify options for the best use of available resources and efforts to support adaptation in smallholder agriculture in Central America. / Bouroncle Seoane, CM.
