Cassava is the main staple crop in many African countries, but the crops are threatened by two major diseases, the cassava mosaic virus disease and cassava brown streak virus, which in the last years have destroyed almost 80 percent of cassava harvests in Africa.

More than three times as much carbon is stored in soils across the world as it is in the atmosphere, making them one of the most important global carbon sinks. Therefore, processes impacting on the soil in which carbon is released, such as deforestation or agricultural activities, significantly contribute to climate change. The debate on the reduction of greenhouse gas emissions from agricultural activities and their consideration in the international climate negotiations has brought soils as carbon reservoirs more to the public eye.

Nerica – New Rice for Africa is the name of the great biotechnological success in rice breeding. What scientists created in the lab using modern methods, namely hybrids of African rice and Asian rice, had already come into being decades ago by chance in West African ?elds.

Large land acquisitions can have a deep, lasting e? ect on livelihoods, food security and the future of agriculture, so there is a need for strategic thinking, vigorous public debate and government responsiveness to public concerns, especially in recipient countries

The recent upsurge in Foreign Direct Investment (FDI) in land raises the hope to bridge the gap of decades of underinvestment in developing countries’ agricultural sector, but it may also threaten host countries’ food security and increase the vulnerability of the rural population. Based on four country case studies conducted by Deutsche Gesellschaft für Technische Zusammenarbeit (GTZ), this article illustrates distinct impacts of large-scale investments in agricultural land.

African Governments are planning to leapfrog development and move to a middle income economy in a short time. This requires a sustainable strong economic growth, based primarily on African agricultural resources and initially with huge resources from outside, partly provided by donors but mainly from the private sector through sustainable and responsible investments. All actors should engage in a serious dialogue on how to facilitate and create good investments in order to attract the necessary resources for development.

Many adaptation measures urgently needed in agriculture today as a consequence of climate change concern water in agriculture and were already devised and implemented in the 1980s as a part of rural development activities. However, most of the experience and knowledge have sunk without trace. Systematic knowledge management at that time would have made it possible to benefit from this experience today in the planning and implementation of water-related adaptation measures, providing effective support for these measures and hastening their implementation.

The world food crisis has spurred foreign direct investments (FDI) into arable land in developing countries. While significant financial inflows into agricultural sectors could be beneficial on a global scale, it could negatively affect local livelihoods. This article provides an overview of the different types of FDI in land. In addition, examples of investment flows are illustrated in an overview and a sustainable impact matrix outlines the occurring effects. Finally, requirements of avoiding negative effects are presented, to achieve a Pareto-efficient win-win situation.

Kenya is still largely agrarian with 80 percent of its population depending on agriculture for food, employment and income. The dilemma facing the country is that only 20 percent of the land is suited for agricultural production. A greater proportion of the country, however, consists of agroecologically less favoured areas (LFAs). Another dilemma in Kenya?s agricultural sector is that economic development impacts are not homogeneously spread even among the agriculturally favoured areas.

Since 1996, the Centres for Agriculture in the Tropics and Subtropics of the Universities of Hohenheim and Göttingen and of Berlin's Humboldt University have organised a conference, the ''Tropentag'', once a year to present and discuss recent findings in research on agriculture and rural development. Other universities, like Kassel-Witzenhausen, have joined in, and the number of participants, papers and posters presented has more than doubled.

Rural areas are not exempted from the impacts of globalisation. Global trends affecting agriculture are particularly significant in this respect. A number of options are available to developing countries in responding to these trends. Given the scarcity of resources it is important that they choose carefully. If they fail to respond, rural areas will become even more marginalized than they are already.

For the first time in the recent history of rural development there is a possibility of creating an infrastructure that dramatically reduces the isolation of rural life. Although ICTs may seem a fragile basis on which to build far-reaching change, a meeting organized by CTA showed that they can speed up the exchange of knowledge and ideas between urban centres and rural communities. In countries struggling to maintain basic amenities, it is the towns that interface most closely with global society.
