The Mara-Serengeti is an ecosystem of immense importance to both Kenya and Tanzania, contributing significantly to the economies of both countries and forming a rich biodiversity reservoir. This ecosystem is among the most threatened ecosystems on the African continent. Increasing human population density and changing lifestyles have escalated demand for ecosystem services including timber and non-timber forest products (NTFPs). These activities have resulted in reduced land productivity and threatened livelihoods. This environmental communication study is aimed at providing a link between effective environmental communication and participatory sustainable natural resource management. It sets out to identify and prioritize natural resource challenges within the Mara region. It subsequently contextualizes the available and effective communication sources and channels to promote participatory approaches to natural resource management in light of several pressures challenging the Mara region. Specific attributes of the community under study are also taken into account in addition to the correlation between the information source and the message.

Protected areas occupy about 27% of Tanzania’s land of 945,000 sq km and contribute 17.5% of its GDP. But who benefits from and pays for the cost of conservation? This study provides insights into these issues based on a survey conducted in the Serengeti ecosystem, involving 20 villages in Serengeti and Loliondo. The results show that villagers received insignificant benefits from conservation compared with the costs they are incurring. Governance of income at the village level was also a major challenge. There was a lack of capacity to handle large amounts of money and little or no planning, transparency, and accountability. It is recommended that income allocation to the communities is increased and external audits of village funds are conducted. Communities should furthermore be allowed to extract resources sustainably in protected areas. Youth should be encouraged to attend higher education and wildlife technical colleges to learn about the values of wildlife. Finally, the governance structures must be improved to make them gender equitable, participatory, transparent, and fully accountable to the communities and all citizens.

The Cartagena Protocol on Biosafety to the Convention on Biological Diversity is an internationally binding instrument addressing issues of biosafety. Biosafety refers to the need to protect human health and the environment from the possible adverse effects of the products of modern biotechnology. Accordingly, all countries to the convention are required to put in place regulatory mechanisms to enhance the safety of biotechnology in the context of the Convention’s overall goal of reducing all potential threats to biological diversity, while taking into account the risks to human health. Therefore, each country party to the convention has its own procedures to enact laws to guide the safe use of biotechnology. In Uganda, the process involves the drafting of the bill by the first parliamentary counsel, approval by cabinet, first reading at the parliament, committal to the responsible parliamentary sessional committee, tabling of the bill for public hearing, consultations, and final approval. In Uganda, the Committee on Science and Technology is responsible for the Biosafety Bill. In March 2013, the Committee tabled the bill for public hearing and submissions from public institutions. There were comments supporting the passage of the Bill and comments in objection. The reasons for objection are mainly due to precaution, speculation, lack of knowledge about biotechnology and biosafety, and alleged influence from biosafety entrepreneurs. This article reviews these public views, revealing controversy and possible consensus to pass the bill.

The Association for Strengthening Agricultural Research in Eastern and Central Africa (ASARECA) through its Agrobiodiversity and Biotechnology Programme is enhancing the utilization of biotechnology research and development innovations in Eastern and Central Africa (ECA). We present successes in the application of biotechnology to enhance the productivity of cassava, sweet potato, banana, maize and sorghum in ECA. These products—drought tolerant maize, sorghum resistant to striga, as well as the technology for producing and distributing disease free planting materials of cassava, sweet potato and banana to farmers—are central for the agro-ecological intensification of farming systems in the central African highlands.

Striga hermonthica (Del.) Benth. is the major biotic constraint to sorghum production. Its control is difficult and can only be achieved through integrated management strategies that depend mainly on host plant resistance and enhanced soil fertility. However, breeding for resistance is hampered by the complexity of host parasite interactions and lack of reliable screening methods. The invention of molecular markers has enhanced the effectiveness of breeding for resistance. Five genomic regions (QTLs) with linked markers associated with Striga resistance were mapped in sorghum variety N13 by [10]. In this study, to increase the efficiency of marker-assisted selection (MAS), 27 EST-SSR markers in close association with Striga resistance QTLs were also identified and mapped. Populations of backcross (BC 3 S 4 ) derived from N13 (Striga resistant) X three farmer preferred sorghum cultivars: Tabat, Wad Ahmed and AG-8 (Striga susceptible) were generated. Thirty-one lines (BC 3 S 4 ) with confirmed Striga field resistance were genotyped with foreground and background selection makers. Twenty resistant lines, with two or more major QTLs were selected for regional evaluation. Of these 10 lines were selected and advanced for multi-location testing, together with Wad Ahmed, Tabat, AG-8, N13, SRN39 and IS9830 as checks. Standard variety trials were conducted in Striga sick plots over three seasons (2009-2011) in Sudan, Gezira Research Station, Damazine, Sinnar, and Gedarif. Results revealed that four lines (T1BC 3 S 4 , AG6BC 3 S 4 , AG2BC 3 S 4 and W2BC 3 S 4 ) were Striga resistant and agronomically superior with yields ranging from 180% to 298% higher relative to their recurrent parents. This Striga resistance coupled with superior attributes of the recurrent parent (including very high yield potentials, high grain quality and drought tolerance) will provide adaptation and stability across a wide range of environments. These are the first products of DNA markerassisted selection (MAS) in sorghum released for cultivation by farmers in sub-Saharan Africa.
