Seed Governance in Tanzania: Seed Capitalism, Pluralism, and Sovereignty Discourses Compared, and the Value of Nuance

Moore, Karen 03 January 2019 (has links)
This thesis explores debates around seed governance in the context of Tanzania’s recent changes to its seed policies and laws, in order to critically examine the framings and discourses employed. Three narratives emerge, Seed Capitalism, Seed Pluralism, and Seed Sovereignty. Consistent with Westengen (2017), Seed Capitalism and Seed Sovereignty rely on, and are entrenched in, binary opposition, despite the complexity of the problems involved, and put forward singular solutions that risk harming smallholder resilience. Seed Capitalism portrays scientist-bred certified seed as superior to farmer varieties, and as optimal for smallholders, despite evidence to the contrary. Seed Sovereignty constructs rigid distinctions between peasant seeds and industrial seeds, failing to engage with the phenomenon of creolized seed, the intermixing of farmer varieties with scientist-bred varieties. Creolized seed presents a narrative threat to Seed Sovereignty’s rejection of industrial seed. Both Seed Capitalism and Seed Sovereignty narratives obscure evidence relating to seed quality and yield that is in tension with their underlying agendas. A third discourse, Seed Pluralism, not previously identified as such by the literature, resists binary framings and recommends a multiplicity of approaches informed by the nuance of relevant facts. Tanzania’s seed governance framework predominantly reflects the Seed Capitalism discourse. While Seed Pluralism has a small foothold in Tanzania’s seed governance, through the Quality Declared Seed (QDS) system, overall Tanzania’s seed laws are threatening smallholder resilience. Positive reform under Tanzania’s current political settlement is unlikely. Pro-poor donors should withdraw support for governance frameworks rooted in Seed Capitalism, and instead promote seed governance reforms grounded in Seed Pluralism, including eliminating restrictions on smallholder seed exchange in low income countries.

Understanding farmer seed systems in Sespond, North West Province

Kganyago, Mpho Clementine January 2020 (has links)
Farmer-led seed systems (FSS) provide the backbone for small-scale farmers and many rural communities that use traditional methods of farming to produce seeds that grow and adapt to local conditions. FSS differ from one community and farmer to the next, depending on the methods and practices used to maintain seed varieties. Seed diversity can enhance FSS by improving livelihoods and strengthening farmers' networks, thus contributing to resilient communities. Although nuanced, the dualistic agricultural system in South Africa consists largely of subsistence (small-scale) and commercial (large-scale) farming and includes different crop management systems and post-harvest practices. In South Africa, maize (Zea mays) is a major staple grain crop with a significant role as animal and poultry feed. The North West region is one of the highest white-maize-producing provinces in South Africa. Maize seed systems include both traditional, openpollinated varieties (OPVs) and cultivars such as modern hybrids and genetically modified (GM) seed varieties, including those engineered for specific purposes. The dominant GM maize is that designated for pest resistance using Bacillus thuringienesis (Bt), a soil bacterium which produces a toxin that is fatal to a wide variety of insects such as moths and flies. Many small-scale farmers prefer their own traditional seeds for breeding, planting, selection, selling and consuming. However, FSS based on traditional varieties are threatened by modern cultivars which may be introduced in different ways including through seed exchange, purchasing at shops or by pollination from nearby commercial farms. This study was conducted in the Sespond community of the North West Province. The aim of the study was to understand how small-scale farmers in Sespond maintain traditional maize varieties through selection and storage in a complex agricultural landscape that incorporates both formal and informal seed systems. The formal system represents industrialised farms and companies that work with commercial seed. The informal system represents small-scale farmers who rely on their own seed. Qualitative methods included mapping software which was used to obtain visual agricultural data in and around Sespond. Semi-structured interviews were conducted with 30 small-scale farmers to collect information about their farming practices, including the maize varieties planted. Quantitative methods included collecting 20 maize samples from different farmers for genetic analysis. Agdia® immunostrip tests were used to detect for the presence of Crystal protein (Cry protein) produced by the Bt bacterium, engineered to improve the resistance of maize against insects. The results showed that 13 samples were negative for the protein and seven samples were positive for the protein. A key finding is that small-scale farmers are not able to detect the different maize varieties in their seed systems. This represents a threat for traditional seed varieties in the community as without this knowledge, farmers are not able to adequately manage their production and storage systems. Farmers made use of alternative storage methods such as the mill to reduce seed damage they experienced at home. However, the findings of this research showed that there was an increasing risk of farmers' traditional maize being mixed with GM maize at the mill. Farmers' rights to plant and consume traditional maize were therefore undermined. This study recommends that (a) efforts are made to increase awareness among farmers that help to distinguish transgenes from hybrids and traditional maize varieties; (b) measures are implemented at mills to both improve the transparency about the storage and processing of traditional maize and to separate traditional maize from hybrid and GM maize.

Privatiseringen av de växtgenetiska allmänningarna : Konsekvenserna av regimkomplexet kring växtgenetiska resurser för bönders rättigheter och matsäkerhet

Ulaner, Magnus January 2007 (has links)
This thesis discusses the global regime complex concerning the management of plant genetic resources for food and agriculture, and how different regimes concerning these resources cooperate or stand in opposition to each other. Because of changes in US patent law and the establishment of TRIPS, patent claims over plant genetic resources has increased dramatically globally. This, amongst other things, in turn has lead to the development of CBD which in turn lead to the creation of access and benefit laws in many countries. To create a free flow of genetic resources for food and agriculture the ITPGRFA, with its multilateral system, were negotiated. The aim of this thesis is to investigate which consequences the regime complex concerning plant genetic resources for food and agriculture can have on the rights of small farmers, agricultural research and food security in the global South. The thesis shows how patents and strict access laws creates a situation where more and more actors has exclusive rights which excludes others from using these, for the global food security, essential resources. Further it is shown that there also are processes going on within the UPOV that risk to take away farmers right to save seeds, and thereby make them dependent on the more and more monopolistic global seed markets dominated by a few multinational corporations. It is established that ITPGRFAs multilateral system is an opening in this hyperownership of plant genetic resources for food and agriculture; but that the international community at the same time has to see to that the patent claims on plant genetic resources not violate farmers’ rights to their resources. / Denna uppsats behandlar det globala regimkomplexet för förvaltningen av växtgenetiska resurser för livsmedel och jordbruk, samt hur avtalen rörande dessa resurser samverkar eller står i motsättning till varandra. I och med förändringar i amerikansk patentlagstiftning och upprättandet av TRIPS har patentanspråk på växtgenetiska resurser ökat dramatiskt, vilket i sin tur påverkade tillkomsten av CBD vilken innefattar upprättandet av lagstiftning rörande tillträde till och den rättvisa fördelningen av nyttor härstammande från, genetiska resurser. För att möjliggöra ett relativt fritt flöde av växtgenetiska resurser har ITPGRFA med dess multilaterala system fram förhandlats. Syftet med denna uppsats är att undersöka vilka konsekvenser den nuvarande globala förvaltningen av växtgenetiska resurser för livsmedel och jordbruk kan få för jordbruksforskning, småbönders rättigheter och matsäkerhet i Syd. Uppsatsen visar på hur patent och tillträdeslagstiftningar skapar en situation där fler och fler parter innehar rättigheter att utestänga andra från att nyttja dessa, för den globala matsäkerheten, essentiella resurser. Vidare visas på hur det samtidigt pågår processer inom UPOV som riskerar att undanta bönder rätten att spara utsäde och därmed göra dem beroende av de i allt högre grad monopolartade frömarknaderna, vilka domineras av att fåtal multinationella företag. Här konstateras även att ITPGRFAs multilaterala system är en öppning i detta hyperägande, men att det internationella samfundet samtidigt måste försäkra att patentanspråk inte kränker bönders rättigheter till sina resurser.
