Change detection is one of the primary applications of remote-sensing data, and many techniques have been developed during the past three decades. Although frequently criticized and despite many alternatives, due to its simplicity and intuitive manner, post-classification change detection still remains one of the most applied techniques. Many studies in the field of change detection analysis acknowledge, for instance, the impact of misregistration, inconsistencies in classification schemes or differences in methods for image interpretation.

While conflict-related dynamics are recognized as causes of land grabbing in Colombia, violent processes of exclusion and expropriation behind ‘greener’ projects are often seen as disconnected from them. The case of ecotourism in Tayrona National Natural Park makes it possible to explore the geographies of violence that sustain tourism in the area and their role in shaping everyday resource politics. This paper shows how green pretexts of paradisiacal spots in need of protection have contributed to privatization and dispossession.

The river basin management approach in the Syr Darya basin fragmented after the disintegration of the Soviet Union. However, this approach had already created dependencies between riparian states, such as transboundary water control infrastructure. At the national level, these states hardly cooperate, but at the province and district level, especially in the Ferghana Valley, which is shared by Kyrgyzstan, Tajikistan, and Uzbekistan, cooperation continues. This paper analyzes transboundary cooperation in the Ferghana Valley.
