Looking beyond national boundaries: regional harmonization of seed policies, laws and regulations

Countries in West, Eastern and Southern Africa are pursuing the regional harmonization of their seed laws and regulations. Common regulatory frameworks are expected to reduce the costs of trading seed and encourage scale economies in seed production. As a result, commercial seed production is expected to expand, providing farmers with improved access to new varieties and stimulating productivity growth. The impact of these harmonization efforts will depend on the details of the regulatory agreements. Policy-makers are being asked to consider a complicated series of trade-offs between stricter measures for quality control and the need to encourage the multiplication and distribution of lower-cost seed. They are also being confronted with two possible views of sectoral development. One view entails the pursuit of better linkages between distinct national seed markets. The second involves the development of truly regionalized seed markets, where seed can be readily produced in one country and sold in any other country. This implies greater regional interdependence of seed supply. The paper compares the harmonization agreements being pursued in each of the three African regions and progress in implementing the accords. Efforts to adapt international seed market standards to the contingencies of African markets are discussed and priorities for further policy analysis are identified

Participatory Technology Development and Transfer: The Key to Soil Fertility and Water Management Technology Adoption in Zimbabwe. Report No. 2

There are few non-farm engines of growth and poverty alleviation in most sub-Saharan African (SSA) countries. This implies that smallholder agriculture is likely to remain the major source of rural growth and livelihood improvement for a long time to come, as well as the center of individual nation’s economic growth (World Bank 1997). Many sources continue to establish that the persisting impoverishment of rural SSA is due to declining land productivity under an increasing population that uses low input farming methods (IFAD 1994; World Bank 1996; Woodhouse 2002). In addition, farmers have invested little in soil fertility management and crop yield despite decades of research (Ryan and Spencer 2001; Mapfumo and Giller 2001; Scoones 2001). The consequence of this is widespread accelerated erosion, degradation of soils, and deforestation (Hoffman and Ashwell 2001). As the natural resource base is degraded, it is becoming increasingly difficult for resource-poor farmers to maintain their livelihoods and quality of life

Assessing the Impacts of Zimbabwe’s Agricultural Vouchers Input Program

Using data from ICRISAT 2010/11 household and fertilizer retailer surveys, the study reveals that open vouchers enhance farmers input choice. The targeting of vulnerable farmers was efficient in selecting, households with less livestock ownership and those affected by HIV/AIDS. The use of open vouchers enabled retailers to sale agricultural inputs, boost revenue and link them to suppliers. The use of open voucher is preferable in areas where retailer’s infrastructure and mobile telephone network coverage is good. Timely payment of retailers and suppliers is necessary to encourage their willingness to participate in the program. Risk bearing options like wholesaler insurance are critical to ensure wholesalers are compensated in the event that agro-inputs are not purchased. Credit facilities specifically meant for retailers to stock and trade agricultural inputs will be useful. Programs and policies that enable farmers to access credit to buy inputs should also be put in place. A well planned voucher system links commercial retail channels and has multiplier effects to the society. Experiences from the PRP input program demonstrated that voucher system, as an alternative to direct input distribution, is workable in the Zimbabwe situation and can be adequately supported by suppliers and rural retailers. Voucher programs have the potential to support retail linkage and there is need for increasing more stakeholders, such as seed and fertilizer companies, and wholesalers

Mineralogical alterations in calcite powder flooded with MgCl2 to study Enhanced Oil Recovery (EOR) mechanisms at pore scale

Seawater injection into chalk-reservoirs on the Norwegian Continental Shelf has increased the oil recovery and reduced seabed subsidence, but not eliminated it. Therefore, understanding rock–fluid interactions is paramount to optimize water injection, predict and control water-induced compaction. Laboratory experiments on onshore and reservoir chalks have shown the need to simplify the aqueous chemistry of the brine, and also the importance of studying the effect of primary mineralogy of chalk to understand which ions interact with the minerals present. In this study, the mineralogy of the samples tested, are simplified. These experiments are carried out on pure calcite powder (99.95%), compressed to cylinders, flooded with MgCl2, at 130 °C and 0.5 MPa effective stress, for 27 and 289 days. The tested material was analysed by scanning and transmission electron microscopy, along with whole-rock geochemistry. The results show dissolution of calcite followed by precipitation of magnesite. The occurrence and shape of new-grown crystals depend on flooding time and distance from the flooding inlet of the cylinder. Crystals vary in shape and size, from a few nanometres up to 2 μm after 27 days, and to over 10 μm after 289 days of flooding and may crystallize as a single grain or in clusters. The population and distribution of new-grown minerals are found to be controlled by nucleation- and growth-rates along with advection of the injected fluid through the cores. Our findings are compared with in-house experiments on chalks, and allow for insight of where, when, and how crystals preferentially grow

Constraints, Challenges, and Opportunities in Groundnut Production and Marketing in Malawi Report No. 4

Malawi is a landlocked country in southern Africa bordered by Tanzania, Mozambique, and Zambia and covers an area of about 118,000 km2. The country is a member of the Southern African Development Community (SADC) and the Common Market for Eastern and Southern Africa (COMESA) communities in addition to being part of the African Union (AU). It has a population of approximately 14 million people of which 51% are women. The country has one of the highest population densities in Africa and a population growth rate of about 2.4% (GoM 2005a)

National and Regional Livestock Markets: Opportunities for Growth in SADC

The last forty years has seen a continuous rise in the demand for meat, milk, and other livestock products worldwide. Fueled by trends such as increased urbanization, growing populations, and income growth in the urban areas, it is clear that this demand will only continue to grow (Delgado et al., 1999). Although decision makers in agriculture have traditionally focused on crop production, the growing demand for livestock products makes a good case for improving the livestock sector. Gains made here will ultimately benefit the many small-scale farmers who collectively own more than 80% of the livestock in southern Africa (SADC RISDP, 2006)

Characterizing genomic alterations in cancer by complementary functional associations.

Systematic efforts to sequence the cancer genome have identified large numbers of mutations and copy number alterations in human cancers. However, elucidating the functional consequences of these variants, and their interactions to drive or maintain oncogenic states, remains a challenge in cancer research. We developed REVEALER, a computational method that identifies combinations of mutually exclusive genomic alterations correlated with functional phenotypes, such as the activation or gene dependency of oncogenic pathways or sensitivity to a drug treatment. We used REVEALER to uncover complementary genomic alterations associated with the transcriptional activation of β-catenin and NRF2, MEK-inhibitor sensitivity, and KRAS dependency. REVEALER successfully identified both known and new associations, demonstrating the power of combining functional profiles with extensive characterization of genomic alterations in cancer genomes
