Dekolo:

Your question is interesting ...

I'll be back later with more calm.

Densification of cities is seen as perhaps the most sustainable in terms of greater levels of shared infrastructural resources however this has to be coupled with greater synergies between city and countryside so that one sustains the other.

I accept your solution, but the only concern is the fact that people who move to peri-urban areas are either pushed by land or property values or pulled by attraction of nature or need for bigger residential space. It comes from motivation. In the context of Lagos, where planning control instrument is weak, people cannot be restrained from moving to the countryside. This impacts sustainability.

Dekolo:

I suggest reading the articles attached which talk about the Portuguese project PERIURBAN.

According to this study, the peri-urban areas lack adequate conceptual and geographical setting. Mainly because they are areas that integrate features of urban and rural areas and are located between the urban centers and the countryside.

The classical approach to planning has envisaged these areas as spaces of urban expansion and localization of regional and trans-regional infrastructure. The dynamic nature of these areas was identified a few years ago (EEA 2002, 2006). Increasing urbanization has led to the disappearance of traditional activities: agriculture, forest and natural areas, even though the subject of policy instruments and planning themselves, were neglected by the classical spatial planning. In the Portuguese case, some of the regions with higher agricultural competitiveness are located in or near metropolitan areas. Drawing attention to the peri-urban areas should be considered in the context of current global challenges such as increasing migration to urban centers, combating and adapting to climate change, or the need to deal with food safety. These challenges are all the more pressing considering that we look back on more than half of the population in Europe and Portugal.

The main objective of this project is the evaluation of the potential of peri-urban areas in the context of future challenges for sustainable development in a changing world. The project adopts a prospective approach to peri-urban areas of the Lisbon Metropolitan Area (AML), based on their specificity in environmental, social, economic, and institutional terms. The uncertainty regarding the future demand for these territories based exploration of the role of these areas in terms of sustainable development at regional and local level.

The innovation of this project is the perspective adopted because it recognizes the specific nature of peri-urban areas as well as the surrounding areas within a multidisciplinary and participatory approach. In effect, beyond the diversity of disciplines that integrates the design considers the contribution of external actors such as central elements in the main stages of the project, allowing for mutual enrichment in conceptual and methodological terms and an ongoing relationship with the territories in question.

Thank Andrea. I will read the documents and revert.

Dear Andrea, 

The documents you sent are in French. Please can I have a translated copy.

Thanks

Dekolo:

I'm sorry, but I have translated copies.

However, the site, attached, has more information in English.

Hope this helps.

Generally, this paper describe the disintegration of agricultural institution in urban periphery area in Kabupaten Bogor, as a result of the increasing of conversion of agricultural land into non-agricultural area. The study was implemented in Desa Babakan, which characterized by the existence of changing of farmlands. The method used was mixmethod, by combining quantitative and qualitative method. Quantitative and qualitative data collections were conducted simultaneously, and then being analyzed as qualitative sing NVivo and quantitative using Spearman Rank correlation using SPSS. The result shows that shifting land use in Desa Babakan influenced by internal and external factors. Moreover, the change of land use affected on the disintegration of agricultural institutions, that statistically shown by the correlation between land use change and agricultural institutions in the area.
