Net-Map combines participatory action research and social network analysis with a sociological analysis of power relations. The tool helps to identify, visualize and discuss which actors are involved in a given network, how they are linked, what their goals and interests are, and how influential or powerful they are with regard to a specific outcome. The tool is well suited for facilitating interviews with, and discussions among, network actors to address governance challenges and develop personalized solutions. The resulting maps and transcripts canform the basis for qualitative content analysis and quantitative social network analysis. [ABSTRACT FROM AUTHOR]

The diversity in the global food market is expanding as thousands of new products enter the business every year, among which nutraceutical and functional foods hold important positions. The present research work aimed at the nutritional evaluation of three medicinal herbs, i.e., turmeric (Curcuma longa L.), ginger (Zingiber officinale), and black cumin (Nigella sativa). A bread formulation was enriched with the individual/combined supplementation (1–3%) of these herbs. Later, the bread was analyzed for nutritional, rheological, textural, and sensorial characteristics. The results revealed that the herbs improved the nutritional composition of bread, especially ash and fiber, as the maximum ash and fiber contents were noticed in T
15 (2.0% dried powder of each plant) with values of 1.64 ± 0.04% and 4.63 ± 0.16%, respectively. The results regarding the rheological behavior showed minor variations in the rheological traits and a slight increase in dough development time up to 4.50 ± 0.20 min in T10 from 2.80 ± 0.13 min in T0 . The sensorial attributes also indicated their marked suitability as external and internal characteristics were least affected by the addition of the herbs. Although some parameters like the crust and crumb colors were affected by the addition of black cumin, showing values of 6.25 ± 0.52 and 4.44 ± 0.19, respectively, in T15 , and aroma characteristics were affected by the addition of ginger, supplementation with a combination of herbs at lower doses mitigated the adverse effects of other herbs. Moreover, shelf-life extension, especially with the addition of turmeric powder, was the hallmark of this research. This study concluded that medicinal herbs can be incorporated into baked products to improve the nutritional and sensorial attributes of functional herbal bread. [ABSTRACT FROM AUTHOR]- Published

The project did this through piloting participatory video-based extension on CSA approaches with more than 30,000 farmers in the three countries. The notes in this collection summarize the key methods and findings from the study. It is hoped that they will inspire similar projects and programs that together will help eliminate the gap between rural men and women in resources, agency, and achievement once and for all.

- Abstract
Cocoa is mainly managed by smallholder farmers in the tropics and constitutes one of the most important export commodities, being an important source of income. Lately, conventional cocoa monoculture has been promoted to achieve high short-term productivity at the expense of deforestation. However, such systems have negatively affected the water cycle with more intense heavy rains and longer drought periods, which is threatening food security and human welfare. In that sense, the perception that farmers have on climate change is determinant to the adoption and implementation of adaptation measures and policies in agriculture. Thus, it is imperative a more agroecological approach to answer the question whether and to what extent cocoa farmers perceive and adapt their farming practices to the climatic variations, in conjunction with water use estimations of cocoa systems under different management. As such, the present study includes an analysis of farming practices’ adaptations to climate change and a comparison of evapotranspiration in cocoa cultivation under different management. In Bolivia, traditional cocoa production systems include shade trees. Particularly, cocoa agroforestry systems managed organically have proven to have smaller water footprint and are considered an effective nature-based solution to address climate change, biodiversity loss, food insecurity and rural poverty among other environmental and social challenges of this value chain. This study sought to assess evapotranspiration as a measure of water use in conventional monocultures and organic agroforestry systems in a long-term field trial in tropical Bolivia. In addition, to assess water and climate change-related management issues and their impacts on local rural livelihoods, farmers were interviewed to assess their perception of climate change, the adaptation of farming practices and water management related knowledge. The results provide a joint assessment of the water use, key characteristi

- Abstract
The socioeconomic and environmental benefits of organic farming have been widely explored in research, while topics like gender equity and labour are often neglected. In India, the influence of caste and gender identities adds another layer of complexity to these aspects. Using a case of a research and training project implemented in the Nimar Valley region of Madhya Pradesh since 2007, we explore gender and caste intersectionalities within conventional and organic cotton farming systems. The project promotes organic cotton cultivation and food crop diversification, and trains women from marginalised tribal communities, among others. We use a relational approach, as proposed by David Mosse, to understand differences in organic and conventional cotton farming systems in the representation of caste and gender and concerns and barriers to the involvement experienced by different actors. We interviewed 80 respondents employing participatory social network mapping, gendered seasonal calendars, in-depth interviews and participant observation in training, applied during a three-month fieldwork in 2022/23. Preliminary results show among others that, representation in terms of caste and gender has been static in both conventional and organic farming systems. Mainly females from scheduled castes (SC, Dalits) and scheduled tribes (ST, Tribals) are represented as casual labourers in seeding, weeding and cotton picking. The bargaining power of labourers, deciding both wages and working hours, has increased in recent years. This potentially is a positive social change, but puts a higher burden on organic cotton farmers as it is more labour-intensive compared to conventional farming. Our results further indicate that due to high labour wages, there is a resurgence of labour-sharing arrangements for cotton harvesting amongst rich upper-caste farmers and, novel involvement of upper-caste women in cotton farming activities. Tribal farmers in turn start growing conventional cotton. Al

Private companies of all sizes may engage in the integration of refugees into the labour market. Taking the case study of the highly industrialised German city of Stuttgart, this study explores the motivation of (a) private large‐scale international enterprises including (automotive and high‐tech companies) and (b) family‐owned small‐ to medium‐sized companies (private social enterprises, suppliers to the automotive industries, architecture, and engineering companies) to do so. The research further explores the companies' challenges, opportunities and the lessons learned throughout the process. Utilising the principles of Grounded Theory, a qualitative case study approach is applied with in‐depth interviews with private companies, civil society, public private partnerships and experts. The findings show that the arrival of a large number of refugees during 2015/2016 has increased the engagement of the companies, increased their cooperation with other sectors, and has correspondingly led to some innovative initiatives in refugees' labour market integration and policy advocacy. The call for the engagement of the private sector and the existence of employment‐related policies such as tolerated work permits (Ausbildungsduldung/Beschäftigungsduldung) were essential to create sufficient incentives for private companies to engage in the training and employment of refugees. However, the insecure residence permits and bureaucratic procedures in the public sector mostly discouraged their engagement. Our research shows that the two company types had different possibilities, different approaches towards refugees and faced different challenges while engaging in refugee labour market integration.

23. Effect of Farmland Arrangements for the Protection of Natural Areas on the Basic Psychological Needs of the Farmers Involved

Léger-Bosch, Christine and Chervier, Colas
- Abstract
Some studies question the effectiveness of incentive-based environmental public policies (IEPPS) on inducing changes in farmers’ practices due to certain psychological mechanisms. Rooted in self-determination theory, the extant literature notably focuses on the motivation crowding phenomenon while overlooking the central concept of the basic psychological needs (BPN) of humans: autonomy, competence and social relatedness. This article explores farmers’ BPNs and their fulfillment in the case of farmland arrangements for the protection of natural areas (FAPAs). These IEPPs grant access to land at low rents under conditions of environmentally friendly agricultural practices. We analyze interviews with farmers engaged in FAPAs in a French basin with computer-assisted text-based qualitative data analysis methods. FAPAs create a social context that thwarts farmers’ BPN for autonomy due to a noninclusive design that extends beyond constraints on practices. An inclusive FAPA design and support to BPNs for competence and relatedness could improve farmers’ engagement in action.

Dans les territoires périurbains, l’urbanisation croissante se fait principalement au détriment des espaces agricoles, qui disparaissent alors de manière irréversible. Associée à des enjeux environnementaux mais aussi alimentaires, la préservation de ces espaces est devenue un enjeu majeur de la politique d’aménagement du territoire. Dans ce contexte, des initiatives innovantes émergent via une intervention directe sur le marché foncier, avec l’objectif de préserver l’usage agricole sur le long terme. Cet article présente une première analyse de ce phénomène relativement récent: les «opérations de portage foncier ».

- Abstract
Non-PR, IFPRI1; 1 Fostering Climate-Resilient and Sustainable Food Supply; G Cross-cutting gender theme; Reaching Smallholder Women; CRP2, EPTD; PIM, CGIAR Research Program on Policies, Institutions, and Markets (PIM), In sub-Saharan Africa, female-managed plots often show a significant gap in productivity compared to men's plots. To examine these differences, a variable to determine who in the household controls agricultural plots is needed. There is variability in the ways in which gendered control over agricultural plots is defined and measured across studies. Many studies show that an in-depth analysis of intra-household relationships is necessary, as this is often a major unexplained factor in productivity differences. To contribute to filling this methodological gap, we estimate the productivity gap among male and female farmers in Uganda using three different identification approaches and conduct complementary qualitative research to investigate the underlying causes of these differences. The three approaches to define control over plots are: (1) gender of the plot manager, (2) gender of the main plot-level decision-maker and (3) on gender of decision-maker over income from the sale of crops. Results show significantly different gender productivity gaps of 16% (1), 43% (2) and 60% (3). Qualitative results confirm the variability in the way that households defined plot management, including multiple ways in which decisions are made or activities are distributed within households on jointly managed plots. Mixed-method research designs and improved gender variables for econometric models can contribute to a better understanding of gender productivity differences and better policy making aiming to reduce gender inequalities.

En France, les exploitations agricoles ne sont pas propriétaires de toutes leurs terres et les louent en grande partie (61,7 % en 2010, Courleux, 2011). La question de savoir à qui appartiennent les terres agricoles est donc cruciale car : 1) une grande partie de l'agriculture est pratiquée sous forme de bail ; 2) y répondre pourrait éclairer de nombreuses questions d'actualité pour le développement rural (retraite des agriculteurs, élargissement des exploitations, développement urbain, accaparement des terres...). Il existe un manque de connaissances dans la littérature sur ce sujet, dû à la rareté des données disponibles. Nous proposons de contribuer à combler ce manque en mettant en œuvre une intersection de données individuelles et spatialisées sur les propriétaires (données sur la fiscalité foncière) et sur les utilisateurs (politique agricole commune) visant à apporter des éléments d’analyse territoriale. Ce travail vient contribuer à la dynamique initiée par de précédents travaux basés sur le même principe (FNSAFER, 2015 ; CEP, 2016). Il s’agit d’un premier test et d’une contribution d’ordre méthodologique. La méthode utilisée est celle d’une programmation informatique (langage Python) permettant le croisement de deux bases d’informations géo-référencées. Cette programmation vise à construire une nouvelle base de données basée sur le concept d’Unités Propriété-Usage, qui sont des polygones croisant l’information sur la propriété (parcelle cadastrale) et l’usage (îlot PAC) sur une même surface. D’une part, nous établissons des statistiques régionales sur les profils d’exploitations agricoles et les analysons de manière descriptive. D’autre part, nous produisons des moyennes sur ces profils à l’échelle communale nous permettant l’édition de cartes et d’une première analyse spatiale. Cette méthode et son premier test en Région Auvergne-Rhône-Alpes ont permis de surmonter les contraintes techniques des SIG (comment interpréter de manière informatique les différences de tracés des limites entre deux bases aux projections et méthodes de relevé différentes), d’appréhender celles liées aux lois sur la protection des données, de déterminer les limites de la méthode, et d’établir le potentiel d'analyse dans le cadre des contraintes données. L’exemple de la Région Auvergne-Rhône-Alpes permet d’illustrer les éléments de diagnostic qu'elle est susceptible d’apporter sur la relation propriété-usage des terres agricoles. Ainsi, en région Auvergne-Rhône-Alpes, une exploitation agricole représente en moyenne 89 parcelles cadastrales et 21 îlots de culture (au sens de la PAC); 27 "comptes propriétaires" au sens de la Direction Générale des Impôts Publics, chacun d'entre eux maîtrisant 3 parcelles cadastrales de l'exploitation. Ces "comptes propriétaires" se composent de 38 "droits de propriété" (toujours au sensde la DGFIP), dont 20 en indivision. Les terres agricoles auvergne-rhône-alpines déclarées à la PAC en 2015 sont détenues à 60,3% par des personnes physiques, à 29,4% par des indivisions de personnes physiques, à 4,9% par des personnes morales privées, à 3,5% par des collectivités locales et syndicats mixtes, à 0,3% par l'Etat, la Région ou les Départements, et à 0,3% par des établissements publics. De premières hypothèses peuvent être émises par zones dans le territoire auvergne-rhône-alpin. Elles devront être vérifiées par des recherches qualitatives et quantitatives ultérieures. Ainsi, •des zones présentant des enjeux liés à la non-transferabilité des exploitations agricoles pourraient être reconnues sur la base du regroupement des caractéristiques suivantes: grandes exploitations, grandes parcelles, grandes cultures, concentration de la propriété. •des zones présentant des enjeux liés à la un intérêt d'ordre financier grandissant pour le foncier agricole pourraient être reconnues sur la base du regroupement des caractéristiques suivantes: marché foncier actif, absentéisme des propriétaires, importance de la propriété des personnes morales privées •des zones présentant des enjeux liés à la fermeture de l'accès à la terre pour les candidats à l'installation pourraient être reconnues sur la base du regroupement des caractéristiques suivantes: concentration de la propriété, importance de la propriété locale, concentration spatiale des exploitations agricoles, exploitations de taille moyenne, •des zones présentant des enjeux liés au contrôle social sur l'usage agricole, notamment par la propriété pourraient être reconnues sur la base du regroupement des caractéristiques suivantes: importance des prairies permanentes, importance de la propriété publique, importance des zones protégées d'un point de vue environnemental. En termes d’appui à l’action publique, ce travail permet de reposer les bases méthodologiques d’une démarche d’analyse spatiale du croisement des données sur la propriété et sur l’usage, dans un objectif de diagnostic territorial des enjeux fonciers agricoles.

- Abstract
Agriculture and food industries generate substantial quantities of waste material with a huge potential for bioactive ingredients to be recovered and converted into high-value chemicals. Red beetroot, known for its high content in betalains, natural red pigments, as well as polyphenols, fiber, and nitrate, is experiencing increasing demand, in particular as juice, which is leaving behind large amounts of waste. The present study focused on the recovery of betalains and polyphenols from dried whole beetroot and wet and dried beet pulp waste from the juicing industry. As part of an ultrasound-assisted extraction, ethanol/water-based solvent mixtures were used as they were found to be more effective than single solvents. Enzyme-assisted extraction was initially examined in the case of wet pulp but was not able to retain betalains. Betalains appear to be more stable in dried pulp. Ultrasound-assisted extraction was found to be more suitable to effectively extract both betalains and polyphenols with a high bioactive yield from dried pulp. The total betalain and polyphenol profiles as well as storage stability and antioxidant capacities were evaluated over a period of four weeks after extraction from the dried waste. During the four-week storage, betalains quickly degraded at room temperature in contrast to −20 °C, whereas polyphenols and antioxidative activity were much less influenced by temperature. When compared, dried samples from the beetroot juicing industry demonstrate good betalain and polyphenol extractability; thus, these data indicate that dried beet waste can serve as a good source of betalains for the color industry and other technological sectors.

Agrofuel production in marginal areas can contribute directly to creating employment and improving local livelihoods. Indirectly, through increasing household purchasing power and relaxing financial constraints of smallholder farmers, it can contribute to greater food production and/or food consumption and rural development. These benefits depend, however, largely on the feedstock crop and its processing, land and labour requirements, the business model, value chains and institutional frameworks. Jatropha, a feedstock crop with more benefits than first-generation energy crops like maize, experienced a spike in popularity in the early 2000s due to its value in the biofuel markets of industrialized countries. The majority of plantations and outgrower schemes could not survive what followed: disappointing yields, pests and disease, low oil prices, the 2007/2008 food price crisis, negative narratives, and inadequate funding for further research activities. Despite these challenges, large-scale land investments and new Jatropha projects continue to be undertaken. Madagascar is a country characterized by severely eroded and degraded pasturelands, low agricultural productivity, high vulnerability to climatic shocks, and overwhelming poverty and food insecurity rates. It is hypothesized that the use of marginal lands for labour-intensive agrofuel feedstock cultivation, in otherwise neglected areas, through both public and private investment, will have positive impacts through the provision of wage work in large-scale plantation schemes. Although a number of studies have investigated the rural livelihood impacts of participation in Jatropha cultivation, there is little evidence that quantifies the long-term and indirect effects on smallholder food production and household food security. Against this background, large-scale Jatropha cultivation lends itself well to studying the complex interplay between feedstock and food production, as well as the potential for agricultural and rural development. Such analysis would provide useful insights and implications for cost-effective rural development policies to target poor farmers in remote areas. Drawing on a conceptual framework that highlights the role of smallholder farmers livelihood strategies like off-farm employment and agricultural intensification, and livelihood outcomes like food security, this thesis explores the contribution of large-scale agrofuel feedstock cultivation on marginal land. Three important outcomes, namely household food security, information and innovation spillover effects, and agricultural input use, are studied empirically in three articles, using a comprehensive household panel data set. The data was collected in six survey rounds between 2008 and 2014, in three villages near a large-scale Jatropha project in the Haute Matsiatra region, located in Madagascars Southern Highlands. The first article examines the relationship between wage work for a Jatropha project and household food security. Jatropha cultivation on marginal land is labour intensive and does not compete with food production. Therefore, incomes earned can contribute to increased food security directly as well as indirectly through increased or diversified food production. Using five rounds of household panel data, results show that labour demand from the plantation declined substantially after the build-up phase and Jatropha incomes were mostly used for food and other necessities. Fixed effects models show that Jatropha work contributed significantly to an improved dietary diversity. Despite the possibility to earn income during the lean season, Jatropha work did not lead to a reduction in the more subjective lack of food and led to reduced rice stocks. Both food production and consumption were highly influenced by drought shocks and locust plagues, indicating that complementing income creation strategies with agricultural development strategies might have further positive effects on food security. To shed light on the impact pathway from Jatropha work to agricultural production, the second article explores information dissemination through social networks and through Jatropha workers who are more exposed to modern technologies than control households. In addition to institutional factors, a lack of knowledge and limited extension services for improved agricultural technologies are considered barriers to information dissemination. Using two rounds of the dataset, which contains rich information on social capital and networks as well as knowledge and innovations, determinants of production-relevant knowledge like extension services, credit and marketing opportunities are estimated. Accounting for potential endogeneity with lagged and instrumental variables, the relevance of this knowledge to the adoption of innovations and the cultivation of a formerly taboo legume, as an example of diversification, is tested. The results indicate limited access to information, little knowledge on investment and marketing opportunities, and low adoption of innovations. Knowledge is relevant for both innovation performance and the cultivation of the Bambara groundnut, highlighting the need to increase and improve public extension services and information dissemination in rural Madagascar. Adoption is not only encouraged by knowledge, but also directly motivated through informal social networks. Bambara groundnut spillovers from the biofuel project can be observed, relaxing some of the constraints farmers face concerning access to information, social learning, and cultural norms. The third article explores one specific hypothesized spillover: access to and use of agricultural inputs. Given the very low use of improved inputs in rural areas in Madagascar, this study explores whether improved seed and seed information distributed to farmers encourages farmers to cultivate the seed. The analysis is based on household data gathered between 2012 and 2014 from 390 households in three villages. To investigate the adoption of improved seed, as well as the diffusion of information regarding improved seed, a randomized control trial was applied in 2013. Half of the 390 households were randomly assigned to receive the improved lima bean seed (Phaseolus lunatus), which is specifically bred for dry regions. Of the seed-receiving households, half were randomly assigned to receive information on how to store, plant, and cultivate the improved seed, as the variety was unfamiliar in the region. The control group and the two treatment groups are compared with respect to baseline characteristics, bean cultivation, information exchange with other farmers, legume consumption, and willingness to pay (WTP) for improved bean seed. To account for non-compliance, contamination, and spillover effects, local average treatment effects (LATE) are estimated. Of the seed-receiving households, 54% cultivated the seed, reaping an average yield of 6.3 kg for each kilogram of seed obtained. Seed information did not lead to higher yields. A small significant positive impact of seed distribution on legume consumption is found. WTP is 171% of the local market price for bean seed; provision of free seeds and information did not result in a higher WTP. Based on these findings, this thesis contributes empirical evidence that large-scale agrofuel feedstock production on marginal land can enhance rural livelihoods by offering alternative livelihood strategies especially for poorer households and contributing to improved livelihood outcomes. Accounting for the indirect effects shows important impact pathways on the livelihood strategies of farmers in a remote area. The provision of incentives for private investors, complemented by more public intervention in rural areas, as well as more investment in agricultural research and extension to reduce agricultural production risks, might enhance these spillovers. Agrar-Kraftstoffproduktion auf marginalen Flächen kann zur Schaffung von Arbeitsplätzen und zur Verbesserung lokaler Lebensgrundlagen beitragen. Durch steigende Haushaltseinkommen oder einer Milderung finanzieller Engpässe von Kleinbauern kann Agrar-Kraftstoffproduktion auch indirekt durch Investitionen die Nahrungsmittelproduktion und den -konsum sowie ländliche Entwicklung fördern. Der Gesamtnutzen hängt jedoch maßgeblich von der eingesetzten Energiepflanze und ihrer Verarbeitung, vom Flächen- und Arbeitskräftebedarf, Arbeitsaufwand, vom Geschäftsmodell, Wertschöpfungsketten sowie den institutionellen Rahmenbedingungen ab. Jatropha als mögliche Energiepflanze mit einer Vielzahl von Vorteilen im Vergleich zu Energiepflanzen der ersten Generation wie Mais, erfreute sich Anfang 2000 aufgrund seiner Wertschöpfung in Biokraftstoffmärkten von Industrieländern wachsender Popularität. Die Mehrzahl dieser Plantagen und Vetragsanbausysteme überlebten jedoch nicht aufgrund von enttäuschenden Erträgen, Schädlingen und Krankheiten, niedrigen Ölpreisen, der Nahrungsmittelpreiskrise von 2007/2008 und den damit zusammenhängenden Negativschlagzeilen sowie unzureichende Finanzierung weiterer Forschungsaktivitäten. Trotz dieser Herausforderungen werden weiterhin neue Jatropha-Projekte initiiert und großflächige Investitionen in Anbauflächen getätigt. Hochgradig erodierte und degradierte Weideflächen, niedrige landwirtschaftliche Produktivität Madagaskar ist ein Land mit stark erodierten, eine hohe Anfälligkeit für klimatische Schocks, sowie überwältigende Armuts- und Ernährungsunsicherheitsraten kennzeichnen Madagaskar. Es wird angenommen, dass durch die Nutzung von marginalen Flächen in ländlichen Regionen, die andernfalls von öffentlichen und privaten Investitionen vernachlässigt würden, im Rahmen großflächiger arbeitsintensiver Plantagenwirtschaft positive Effekte durch die damit entstehenden Lohnarbeitsmöglichkeiten erzielt werden. Obwohl einige Studien die Auswirkungen einer Beteiligung an Jatropha-Anbau auf die Lebensgrundlagen ländlicher Haushalte untersucht haben, gibt es kaum quantitative Daten, die langfristige und indirekte Effekte auf kleinbäuerliche Nahrungsmittelproduktion und Ernährungssicherheit der Haushalte belegen. Vor diesem Hintergrund eignet sich der großflächiger Anbau von Jatropha als interessante Fallstudie, um das komplexe Zusammenspiel zwischen Rohstoff- und Nahrungsmittelproduktion, sowie die Potenziale für landwirtschaftliche und ländliche Entwicklung zu untersuchen. Eine solche Analyse könnte wertvolle Erkenntnisse und Implikationen zu kosteneffizienten politischen Entwicklungsmaßnahmen zugunsten armer Haushalte in entlegenen Regionen liefern und damit zur Verbesserung ihrer Lebensgrundlage beitragen. Die vorliegende Arbeit untersucht den Beitrag von großflächigem Jatropha-Anbau auf marginalen Flächen auf der Basis eines konzeptionellen Rahmens, welcher die Rolle von kleinbäuerlichen Lebensstrategien, wie landwirtschaftliche Intensivierung und Beschäftigung außerhalb der Landwirtschaft, sowie deren Auswirkung auf Lebensbedingungen wie zum Beispiel Ernährungssicherheit, hervorhebt. Sie fokussiert sich dabei auf die drei folgenden relevanten Themen: Ernährungssicherheit der Haushalte, indirekte Effekte auf den Zugang zu Informationen und die Nutzung von innovativen landwirtschaftlichen Technologien sowie landwirtschaftliche Betriebsmittel wie verbessertes Saatgut für die Nahrungsmittelproduktion. Jedes dieser drei Themen wird empirisch in einem Artikel untersucht. Die Datengrundlage ist ein umfangreiches Haushaltspanel mit insgesamt sechs Befragungsrunden im Zeitraum von 2008 bis 2014. Die Daten wurden in drei Dörfern erhoben, welche im nahen Umkreis eines Jatropha-Projektes in der Region Haute Matsiatra im südlichen Hochland von Madagaskar liegen. Der erste Artikel untersucht den Zusammenhang zwischen Lohnarbeit auf der Jatropha-Plantage und der Ernährungssicherheit von Haushalten. Jatropha-Anbau auf marginalen Flächen ist arbeitsintensiv und die genutzten Flächen stehen nicht im Wettbewerb zur Nahrungsmittelproduktion. Erzielte Einkommen können somit sowohl direkt zu einer verbesserten Ernährungssicherheit als auch indirekt durch Investitionen zu einer höheren oder diversifizierteren Nahrungsmittelproduktion beitragen. Die Ergebnisse auf Basis der Paneldaten zeigen, dass der Arbeitskräftebedarf der Plantage nach der Aufbauphase deutlich zurückging und das erzielte Einkommen vorwiegend für Nahrungsmittel und andere Bedarfsgüter ausgegeben wurde. Mittels Fixed-Effects-Modellen kann gezeigt werden, dass die Arbeit auf der Jatropha-Plantage signifikant zu einer verbesserten Ernährungsvielfalt beiträgt. Trotz der Möglichkeit, über das ganze Jahr hinweg Einkommen zu verdienen, hat die Plantagenarbeit nicht zu einer Kürzung der Hungerperiode beigetragen. Sowohl die Nahrungsmittelproduktion als auch der Konsum wurden stark durch Dürreperioden und Heuschreckenplagen beeinflusst. Dies impliziert, dass Ansätze zur Einkommensschaffung, die mit landwirtschaftlichen Entwicklungsstrategien kombiniert werden, weitere positive Wirkungen auf die Ernährungssicherheit der Haushalte haben können. Um den Wirkungspfad von Jatropha-Plantagenarbeit auf die landwirtschaftliche Produktion zu beleuchten, untersucht der zweite Artikel die Verbreitung von produktionsrelevanten Informationen durch soziale Netzwerke. Vor allem Jatropha-Plantagenarbeiter haben auf der Plantage besseren Zugang zu Informationen bezüglich landwirtschaftlicher Technologien, Beratungsdienstleistungen, Kredit und Absatzmärkten. Neben institutionellen Faktoren gelten mangelndes Wissen und fehlender Zugang zu landwirtschaftlichen Beratungsdienstleistungen als Hindernis für die Verbreitung verbesserter landwirtschaftlicher Technologien in Madagaskar. Auf Basis von Paneldaten aus zwei der sechs Erhebungsrunden, die umfangreiche Daten zu Sozialkapital, sozialen Netzwerken, produktionsrelevantem Wissen und landwirtschaftlichen Innovationen enthalten, werden mit Hilfe von verschiedenen Regressionsmodellen die Determinanten dieses Wissens wie geschätzt. Um potentieller Endogenität Rechnung zu tragen, werden Variablen aus zurückliegenden Jahren und Instrumentenvariablen eingesetzt, um die Relevanz dieses Wissens für die Übernahme von Innovationen und den Anbau der Bambara-Erdnuss als Beispiel für eine Diversifizierungsstrategie zu bewerten. Die Ergebnisse zeigen einen begrenzten Zugang zu Informationen, wenig Wissen zu Investitions- und Vermarktungsmöglichkeiten und wenig Innovationen. Wissen ist relevant sowohl für die Übernahme von Innovationen als auch den Anbau der Bambara-Erdnuss. Dies unterstreicht die Notwendigkeit, öffentliche Beratungsdienstleistungen und Informationsverbreitung im ländlichen Madagaskar auszuweiten und zu verbessern. Für den Anbau der Bambara-Erdnuss war das Jatropha-Projekt entscheidend: Plantagenarbeiter beobachteten den Anbau dieser Leguminose auf der Jatropha-Plantage und verbreiteten diese Information in ihren sozialen Netzwerken. Der dritte Artikel untersucht den Zugang zu und die Nutzung von landwirtschaftlichen Betriebsmitteln. Angesichts des überaus niedrigen Einsatzes von Betriebsmitteln in den ländlichen Gebieten Madagaskars, analysiert diese Studie, ob an Bäuerinnen und Bauern verteiltes verbessertes Saatgut und wichtige Anbauinformationen diese dazu ermutigt, das Saatgut anzubauen. Die Analyse basiert auf Haushaltsdaten, die zwischen 2012 und 2014 bei 390 Haushalten in drei Dörfern erhoben wurden. Um sowohl die Verwendung von verbessertem Saatgut als auch die Verbreitung von Informationen zu verbessertem Saatgut zu untersuchen, wurde 2013 eine randomisierte kontrollierte Studie durchgeführt. Die Hälfte der 390 Haushalte wurde zufällig einer Versuchsgruppe zugeteilt und erhielt verbessertes Saatgut der Limabohne, einer speziell für trockene Gebiete gezüchteten Leguminose. Fünfzig Prozent der Haushalte, die das Saatgut erhielten, bekamen zusätzlich Informationen bezüglich Lagerung, Aussaat und Anbau, da diese Bohnensorte in der Region noch weitgehend unbekannt war. Die Kontrollgruppe und die beiden Versuchsgruppen wurden hinsichtlich der Ausgangscharakteristika, des Bohnenanbaus, des Informationsaustausches mit anderen Bäuerinnen und Bauern, des Konsums von Hülsenfrüchten und der Zahlungsbereitschaft für verbessertes Bohnensaatgut verglichen. Um Nichteinhaltung, Kontrollgruppenkontamination und indirekte Effekte zu kontrollieren, wurde ein sogenannter lokaler durchschnittlicher Behandlungseffekt geschätzt. 54% der Haushalte, die verbessertes Saatgut erhielten, bauten das Saatgut an und erzielten einen Ertrag von 6.3 kg pro kg erhaltenem Saatgut. Die Anbauinformationen führten nicht zu höheren Erträgen. Eine geringe signifikante positive Wirkung der Saatgutverteilung auf den Konsum von Hülsenfrüchten konnte festgestellt werden. Die Zahlungsbereitschaft beträgt 171% des lokalen Marktpreises für Bohnensaatgut. Freier Zugang zu Saatgut und entsprechende Informationen resultierten nicht in einer höheren Zahlungsbereitschaft. Die vorliegende Arbeit liefert somit einen empirischen Beleg dafür, dass sich großflächige arbeitsintensive Agrarkraftstoffproduktion auf marginalen Flächen positiv auf ländliche Lebensgrundlagen auswirken kann, indem alternative Einkommensquellen vor allem für ärmere Haushalte geschaffen werden und zu verbesserten Lebensgrundlagen beigetragen wird. Indem indirekte Effekte berücksichtig werden, zeigt diese Arbeit wichtige Wirkungspfade von großflächiger arbeitsintensiver Plantagenwirtschaft auf die Lebensgrundlagen von Bäuerinnen und Bauern in entlegenen Gegenden auf. Mithilfe von Anreizmaßnahmen für private Investoren, ergänzt durch mehr staatliche Intervention in ländlichen Gegenden unter Einbeziehung von Kleinbauern sowie mehr Investitionen in Agrarforschung, besonders in Bezug auf Produktionsrisiken und Klimaschocks, könnten diese positiven indirekten Effekte ausgebaut werden.

This article explores to what extent farming preservation or development initiatives from public authorities and/or Non-Governmental Organizations (NGOs) resting upon Long-term and Full Rights Acquisitions (LFRA) of land succeed in preserving farmland. The line adopted is to assess whether this mode of access to land use decreases farm profitability. With this aim, we compare ex ante transaction costs and some other costs and benefits incurred by farmers with access to land use, in the case of LFRAs, with the corresponding costs and benefits associated with the two other major coordination mechanisms, namely, conventional lease arrangements and purchasing transactions. The comparison rests on original data on costs obtained in a survey of farmers within a French region. We find that these farmers incur fewer ex ante exchange costs than by purchasing land and higher ex ante exchange costs than by leasing to an individual owner relative to the total cost of accessing land use. This difference is due to negotiation costs, which are nearly twice as high as in conventional lease arrangements. Our results imply that LFRAs would improve their efficiency by limiting the period and the intensity of tenant involvement in their own implementation without reducing their understanding of tenants’ expectations.

In sub-Saharan Africa, female-managed plots often show a significant gap in productivity compared to men's plots. To examine these differences, a variable to determine who in the household controls agricultural plots is needed. There is variability in the ways in which gendered control over agricultural plots is defined and measured across studies. Many studies show that an in-depth analysis of intra-household relationships is necessary, as this is often a major unexplained factor in productivity differences. To contribute to filling this methodological gap, we estimate the productivity gap among male and female farmers in Uganda using three different identification approaches and conduct complementary qualitative research to investigate the underlying causes of these differences. The three approaches to define control over plots are: (1) gender of the plot manager, (2) gender of the main plot-level decision-maker and (3) on gender of decision-maker over income from the sale of crops. Results show significantly different gender productivity gaps of 16% (1), 43% (2) and 60% (3). Qualitative results confirm the variability in the way that households defined plot management, including multiple ways in which decisions are made or activities are distributed within households on jointly managed plots. Mixed-method research designs and improved gender variables for econometric models can contribute to a better understanding of gender productivity differences and better policy making aiming to reduce gender inequalities.

This paper studies access to and adoption of improved seeds and the diffusion of this information in a remote area in central Madagascar. The analysis is based on panel data gathered from 2009 to 2014 for 390 households in three villages. In 2013 a randomized treatment control design was applied in which 50% randomly selected households from the panel received 1.5 kapoaka (0.6 kg) of improved bean seeds (Pois du Cap/Morombe/Phaseolus lunatus). The beans were especially bred for dry regions and purchased at Fofifa (National Center of Applied Research and Rural Development). Of those households receiving, 50% randomly selected households were given information on how to store, plant and cultivate the seeds, as the distributed variety was unknown in the region and not available in the villages. These three groups are compared with respect to baseline characteristics, bean adoption, cultivation, information exchange with other farmers and diet diversity. 55% of the households that received seeds cultivated them, with an average yield of 3 kg. As non-compliance and spillovers exist, next to the average treatment effect on the treated (ATT), intention-to-treat (ITT) and local average treatment effect (LATE) is estimated. Additionally, willingness to pay (WTP) for improved bean seeds is estimated via the contingent valuation method (CVM). In order to ask the WTP, households were explained the benefits of improved bean seeds, which resulted in a WTP of 171% of the price of beans purchased on the local market., This is a working draft.
