Preparation of soil map using remote sensing and GIS technology

Journal Articles & Books
Décembre, 2014

For efficient utilization of soil and water resources, reconnaissance survey of watershed Godavari valley-5 (GV-5) was carried out in Nashik Soil Survey unit No. 2 for providing comprehensive information characteristics. Representative soil samples from each of eight villages of the sub-catchments of Gangapur were collected. From the record of the area sampled, a sample sketch map for reference was made with the help of magnetic needle. Simultaneously, GPS data was recorded for transferring these points on map/satellite image.

The present report gives the complete description of the preparation of a land use map and also the preparation of a national map of livestock intensity, needed as LUS input. The present method allows the preparation of a multi-country land use map in two weeks with the work of 13 experts, and is comparable to the continuous of 130 working days. Further to that, the LUS has been validated with the support of GIS consultants. The report details the work realised during the workshop describing the LUS preparation for the United Republic of Tanzania.

Land-use change in the Caucasus during and after the Nagorno-Karabakh conflict

Socioeconomic shocks can shape future land-use trajectories. Armed conflicts are an extreme form of a socioeconomic shock, but our understanding of how armed conflicts affect land-use change is limited. Our goal was to assess land-use changes related to the 1991–1994 Nagorno-Karabakh conflict between Armenia and Azerbaijan in the Caucasus region. We classified multi-temporal Landsat imagery, mapped land-use changes during and after the conflict, and applied matching statistics to isolate the effect of the conflict from other potential drivers of land change.

Interpretation of characteristics of the land use change based on chronological satellite imageries of kharga oasis, western desert, Egypt

Since the 1990s, the Egyptian government has embarked on two national projects on settlement and agricultural development in the Western desert in preparation for expected future population growth. One of them is the Toshka irrigation project, which carries water from Lake Nasser through the depression of El Kharga towards Farafra Oasis. Another is the East Oweinat project, which has enlarged agricultural land in the south of the Western desert by developing water resources from underground aquifers of Nubian sandstone.

Winter wheat growth monitoring using multi-temporal TerraSAR-X dual-polarimetric data

This paper describes a method for monitoring winter wheat growth using multi-temporal TerraSAR-X dual-polarimetric data. Six TerraSAR-X HH/VV images were collected in Hokkaido, and the temporal responses to the winter wheat fields were analyzed. The height, moisture content and dry matter of the crops were measured at nearly the same time as TerraSAR-X data was acquired, and the relationships between these parameters and SAR data, including sigma naught and coherence, were studied. Quadratic relationships between the crop height and sigma naught were observed for HH polarization.

Application of multi-temporal TerraSAR-X data to map winter wheat planted areas in Hokkaido, Japan

Winter wheat is an important crop for many countries, and monitoring of its planted area is considered important. Optical sensors have been used to monitor agricultural land, and have shown good classification and monitoring capabilities. However, observations using optical sensors sometimes suffer from interference due to cloud cover or rain. In contrast, synthetic aperture radars (SAR) can be used for Earth observation even under rainy, cloudy or dark conditions, hence SAR is expected to be effective in monitoring agricultural fields and identifying winter wheat fields.

Regional Development Scenario Evaluation through Land Use Modelling and Opportunity Mapping

Peer-reviewed publication
Septembre, 2014

In the context of sustainable urban development, the application of selected indicators integrated with scenario simulation and analysis can contribute to evidence-based decision making. This paper discusses the application of land use modelling and opportunity mapping approaches to evaluate regional development scenarios for the Greater Dublin Region in the period to 2026 evolving from research initially developed with the Dublin Regional Authority.

Mapping of pastoral corridors: practices and politics in eastern Senegal

Journal Articles & Books
Septembre, 2014
Sénégal

The delineation and protection of transhumance corridors are increasingly seen as critical to maintaining livestock mobility in agropastoral areas of West Africa by allowing passage through areas of increasing cropping pressure. Understanding the local politics surrounding the mapping and protection of transhumance corridors is important for policy formulation. This study reports the findings of group meetings in nine local districts (communautés rurales) in eastern Senegal about recently mapped corridors.

Kenya

The first set of the land laws were enacted in 2012 in line with the timelines outlined in the Constitution of Kenya 2010. In keeping with the spirit of the constitution, the Land Act, Land Registration Act and the national Land Commission Act respond to the requirements of Articles 60, 61, 62, 67 & 68 of the Constitution. The National Land Policy, which was passed as Sessional Paper No. 3 of 2009, arrived earlier than the Constitution, with some radical proposals on the land Management.
