The debate about the e? ects of migration is still centred on economic aspects. However, the return of migrants also changes the society and cultures of their country of origin. These changes are particularly pronounced where women have emigrated and return to their communities after several years’ absence.

Rural development and urbanisation are often seen as competing, but in most cases are intimately linked. It is essential that policies re? ect and support the many positive links between rural and urban areas, enterprises and people. This in turn requires a better understanding of urbanisation processes and the role of small towns.

More and more young people are leaving the rural areas and migrating to the cities. Although the industrial and the developing nations come from different starting points, such migration ultimately has the same effect on village life and the rural areas everywhere. In the industrial nations the agricultural population is ageing.

Migration is a huge phenomenon. The share of migrants in industrial countries’ populations doubled over the past three decades, and remittances ? ows to developing countries are larger than foreign investment or overseas aid. In many developing countries the percentage of the population working abroad and the percentage of Global Domestic Product (GDP) represented by remittances run into double digits.

Burkina Faso is already using all its possible farmland. In future the only way to feed the rapidly growing population will be by increasing yields on existing land. Building stone contour lines enables rainwater to be better used and slows erosion.

The sheer number of refugees from Zimbabwe puts a heavy burden on the province of Limpopo in South Africa. These new arrivals strain the already weak structure of the local labour market. The result is frustration and bitterness for local people.

Surveys over several years in the Kagera region of Tanzania have shown that migration has a positive impact on people's living standards, even for those who remain in agriculture. On the other hand, there is evidence of migrants ending up in unfavourable social environments and perhaps even that the traditional home communities are protecting their livelihood and survival by setting up subtle exit barriers, in the form of norms, preventing migration of their most productive members. So, should migration be encouraged at all costs?

In today’s China, about 220 million rural migrant workers are on the move – this is more than two thirds of the US population – and their number is set to increase in the course of the country’s urbanisation process. At a rate of 47 percent, still below global average, and against the backdrop of a marked rural-urban divide, urbanisation is not only an effect of rapid economic development, but also forms part of the Chinese government’s economic development strategy.

Labour migration, primarily to Côte d’Ivoire, masked the high rate of natural population growth in Burkina Faso for many years. However, since a political crisis began in this neighbouring country in late 1999, many Burkinabe have returned home. This posed major challenges, especially for rural areas. In the south of the country, shrewd population policy and appropriate rural development programmes have been e? ective in meeting these challenges.

The livelihoods of many rural dwellers are dependent on having secure and equitable access to land. Tenure security is also a prerequisite for sustainable land management. The massive interest of commercial investors has increased the pressure on land globally. This article describes the international community’s efforts to improve the responsible governance and management of land.

The years of war have led to a rapid decline in the nutritional status of people in the Democratic Republic of Congo. To cover their protein requirements, the rural population in the Kivu region in the east of the country have turned to raising guinea pigs. For many families these rodents are nowadays not just a vital element of their food security, but also an essential source of income.

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.
