    Digital technologies are slowly spreading in agriculture sectors globally. But their adoption is hampered by the digital divide which requires significant public investments, improved policy and incentive frameworks to be bridged. Only after that, digital transformation will take place at scale. DAP is meant to assess the country's readiness for this digital transformation by identifying main bottlenecks, opportunities and risks for digital transformation. DAP will thus guide public investment and policy work to accelerate the scaling up of digital transformation.

    Kenya

    A study was undertaken along land use gradients in Taita-Taveta district, southeast Kenya to evaluate the occurrence of arbuscular mycorrhizal fungi (AMF) in seven land use types (LUT). The gradient was from indigenous forest (IF) to croplands with coffee (CO), maize (MA), horticulture (HT), napier (NA) and planted forest (PF). A total of 12 AMF morphotypes comprising of 4 Glomus, 1 Claroideoglomus, 5 Acaulosporaceae, 1 Racocetra sp. and 1 Gigaspora were isolated from the study site. Occurrnace of

    Send a Cow (SAC) is a nongovernmental organization (NGO) that has been working in Kenya since 1996. It focuses on groups of smallholder farmers, providing them with training in sustainable agriculture and improved animal management. SAC is mostly active in western Kenya, one of the country's most populated and poorest region. The population density for this region ranges from 337 to 1,300 inhabitants per km² with an average density of 590 people per km2 (Kenya Ministry of Agriculture and Rural Development, 2001; KNBS, 2010).

    Chemical analysis and missing element trials with Sorghum vulgare L. showed that three Panamanian soils, representative of three great soil groups, were deficient in both nitrogen (N) and phosphorus (P). When a greenhouse trial was undertaken to test the response of Cajanus cajan to rhizobial inoculation, N and P fertilization in these soils, no response was obtained in either the Río Hato or Los Santos soils. There was a definite response to P and a slight response to inoculation in the Pacora soil, which had the poorest fertility level. N applications depressed nodulation.

    Biological nitrogen (N2) fixation in both free-living and symbiotic organisms is an energy-requiring process dependent upon a supply of carbon and energy. In this paper the energy costs for N2 fixation and nodule respiration in symbiotic systems are compared with those of free-living N2-fixing systems, with the theoretical energy requierement for N2 fixation, and with the cost of utilization of combined N.

    This analysis of global and Asian markets looks at protectionism and substitution (decline in starch trade, rise in trade of cassava feedstuffs) and the Asian regional market for cassava feedstuffs. The degree of substitution between cassava and grains has increased measurably during the postwar period. Cassava's future in world markets depends on its ability to compete with grains; so far this has depended on grain pricing policies and tariff structures of importing countries, making cassava trade more vulnerable than the international grain trade.

    Our goal is to provide the scientific basis for development investments and policies that promote more productive, profitable agriculture, and healthier diets at no environmental cost. Low-income, smallholder farmers face significant challenges across sub-Saharan Africa (SSA). High population growth is coinciding with migration to the cities as younger populations seek out higher income-earning opportunities. Inadequate infrastructure and few markets for agricultural production in rural areas, for example, are leading to stagnated opportunities for smallholders.
