In this short article the author indicates the present stages of development of variety evaluation, testing, certification, production and marketing of quality seed—of cereals, industrial crops, pasture plants and vegetables—in major geographical regions of the world and draws attention to some of the underlying problems which must be faced in the future if further progress is to be made.

Access Information

The literature from some selected developing countries has demonstrated that rural smallholder farmers need various information sources in pursuit of their goals of increasing production and improving their living standards. According to the sampled studies, the majority of smallholder farmers access information on crop production. Smallholder farmers are aware of information sources despite challenges faced in accessing and using information. The majority of smallholder farmers access information through personal experiences, family members and friends. Despite access to various information sources, the literature has shown that smallholder farmers face various challenges in accessing and using information sources. The major challenges reported by the literature are lack of mobility, lack of finances, lack of rural information centres, and lack of visits by extension officers. The review has highlighted the lack of literature on the information behaviour of smallholder farmers in Malawi despite the fact that the country is an agricultural economy. The review is adapted from the Masters of Library and Information Science (MLIS) thesis authored by Austine Phiri at Mzuzu University.

<p>Agricultural infrastructure plays important roles in boosting food production and trade system in developing countries, while as being a ‘grey solutions’, generates increasingly risks on the environmental sustainability. There is little information on impacts of agricultural infrastructure developments on water consumption and flows, (i.e. water footprint and virtual water flows) related to crop production, consumption and trade especially in developing countries with high water risk. Here we, taking mainland China over 2000-2017 as the study case, identified and evaluated the strengths and spatial heterogeneities in main socio-economic driving factors of provincial water footprints and inter-provincial virtual water flows related to three staple crops (rice, wheat and maize). For the first time, we consider irrigation (II), electricity (EI) and road infrastructures (RI) in the driving factor analysis through the extended STIRPAT (stochastic impacts by regression on population, affluence and technology) model. Results show that the II, EI and RI in China were expanded by 33.8 times, 4.5 times and 2.4 times, respectively by year 2017 compared to 2000. Although the II was the most critical driver to effectively reduce the per unit water footprint, especially the blue water footprint in crop production (i.e., increasing water efficiency), the developments of II led to the bigger total water consumption. Such phenomenon was observed in Jing-Jin region, North Coast and Northwest China with water resource shortage. The EI and RI had increasing effects on provincial virtual water export, and the corresponding driving strengths varied across spaces. Obviously, the visible effects from the agricultural infrastructures on regional water consumption, water productivity and virtual water patterns cannot be neglected. </p>

During the last half-century, advances in crop production came from expansion in areas irrigated from more intensive application of fertilizers and crop protection chemicals, and from crop varieties that were more responsive to technical inputs and management. Advances in animal production came from genetic improvements and advances in animal nutrition. Differences among developed and developing countries in output per hectare and per worker have widened. If these gaps are to be narrowed agricultural research capacity in developing countries will have to be substantially strengthened.

Food Requirement

The genesis of the problem of food production and nutrition of African, Asian and Central and South American countries can be traced back to the beginning of ‘inter-continental trade’ and the emergence of colonialism. Indigenous food patterns and social and economic orders that had evolved to befit the inhabitants and the environment were destroyed. A nutritional framework and an agricultural and economic policy designed to benefit the colonising nations were fostered. At present, millions of people in the developing countries suffer from endemic undernutrition and associated diseases. Famine is always present under the surface claiming families and individual hamlets and breaks through when the semblance of equilibrium between minimal food requirement for survival and supply is disturbed by natural or man-made disaster. Landlessness, an uneven distribution of wealth, overemphasis on cash-crop production, neglect of peasant agriculture in favour of unnecessary expenditure on military hardware and other misguided projects, and crop specialisation are some of the factors responsible for food shortage and undernutrition. Moreover, most of the staple foods of the developing countries are of low energy density and deficient in some essential nutrients. The cycle of undernutrition, hunger, disease and death can only be broken by instituting a well planned, peasant-orientated, integrated development programme based on self-reliance and self-sufficiency.

High Parasite

Worldwide, unsanitary conditions are responsible for more than three million deaths annually. One of the reasons is the low level of sanitation in developing countries. Particularly, sludge from these regions has a high parasite concentration and low heavy metal content even though the available information is limited. Different issues needed to achieve a sustainable sludge management in developing nations are analysed. Based on this analysis some conclusions arise: sludge management plays an important role in sanitation programs by helping reduce health problems and associated risks; investments in sanitation should consider sludge management within the overall projects; the main restriction for reusing sludge is the high microbial concentration, which requires a science-based decision on the treatment process, while heavy metals are generally low; adequate sludge management needs the commitment of those sectors involved in the development and enforcement of the regulations as well as those that are directly related to its generation, treatment, reuse or disposal; current regulations have followed different approaches, based mainly on local conditions, but they favour sludge reuse to fight problems like soil degradation, reduced crop production, and the increased use of inorganic fertilizers. This paper summarises an overview of these issues.

Address Climate Change

Agriculture is the economic back-borne of majority of developing countries worldwide. The sector employs over 50% of the working population and contributes about 33% of the Gross Domestic Product (GDP) in majority of African states. However, such contribution by the agricultural sector is likely to be affected by climate change, increasing human population and urbanization which impact on available agricultural land in various ways. There is thus an urgent need for developing countries to create or adopt technologies such as; soil-less farming that will not only address climate change challenges but also enhance crop production for improved food security. This paper reviews the science, origin, dynamics and farming systems under the soil-less agriculture precisely hydroponic farming to assist in widening the scope of knowledge of the hydroponic technologies and their implementation in Africa.
