Land suitability analysis for agriculture in the Abbay basin using remote sensing, GIS and AHP techniques

Journal Articles & Books
декабря, 2016
Ethiopia

To meet growing population demands for food and other agricultural commodities, agricultural land-use intensification and extensification seems to be increasing in the Abbay (Upper Blue Nile) basin in Ethiopia. However, the amount, location and degree of suitability of the basin for agriculture seem not well studied and/or documented. From global data sources, literature review and field investigation, a number of agricultural land suitability evaluation criteria were identified.

Press the button: online/offline mobile applications in an agricultural context

Journal Articles & Books
декабря, 2016

In many developing countries, smartphone and internet usage has become a revolution for the population and has opened up many possibilities to use new services for communication purposes. For researchers and development organizations, it is now possible to engage more directly with beneficiaries during the implementation phase of a project. However, many regions still face the problem of a non-existent or unreliable internet connection, which is why mobile applications have to be able to work offline as well as online.

The prospect of GIS technology to create and to use of soil maps is stated. Conducted a GIS analysis of soil cover the territory of Cherven District showed the predominance of retisols of large areas isomorphic and asymmetrical shapes, three times less than the average area for podzols with isomorphic form. The most complicated form of areas marked for alluvial soil types. Their coefficients of irregularity boundaries typically less than 0.2, and are fluvial forms of areas.

Spatio-ecological complexity measures in GRASS GIS

Journal Articles & Books
декабря, 2016

Good estimates of ecosystem complexity are essential for a number of ecological tasks: from biodiversity estimation, to forest structure variable retrieval, to feature extraction by edge detection and generation of multifractal surface as neutral models for e.g. feature change assessment. Hence, measuring ecological complexity over space becomes crucial in macroecology and geography. Many geospatial tools have been advocated in spatial ecology to estimate ecosystem complexity and its changes over space and time.

Questioning the use of ‘degradation’ in climate mitigation: A case study of a forest carbon CDM project in Uganda

Peer-reviewed publication
декабря, 2016
Uganda

An urgent need to stop degradation is frequently cited as support for climate mitigation efforts involving forests. However, lessons learnt from social science research on degradation narratives are not taken into consideration. This creates a risk of problematic degradation narratives being used to legitimise forest carbon projects. This study examined a Clean Development Mechanism (CDM) forest plantation in Uganda, where incomplete and partly contradictory evidence on land use change was interpreted in a way that overemphasised degradation.

It took scientists more than three decades to transform a perceived desertification crisis in the Sahel into a non-event. Looking beyond the Sahel, the chapters in this book provide case studies from around the world that examine the use and relevance of the desertification concept.

Towards Open Source Kenya: Creating and Sharing a GIS Database of Nairobi

Journal Articles & Books

Kenya

In order to make good decisions about the future direction of cities we need data to contextualize
and make recommendations that are based on past results and potential models for the future. Yet
access to information including GIS is challenging, particularly as data is often seen as a
commodity or source of power by those who control it, a dynamic more severe in contexts like
Kenya. By generating GIS data for our own transportation model and then sharing it with those

Fine-grained detection of land use and water table changes on organic soils over the period 1992⿿2012 using multiple data sources in the Drömling nature park, Germany

The construction of consistent time series of land use presents a key challenge when accounting for elective land use-based activities under the Kyoto Protocol (wetland drainage and rewetting (WDR), cropland management (CM) and grazing land management (GM)), in which current land use-driven greenhouse gas emissions are compared to a reference situation in 1990. This case study is the first to demonstrate the feasibility of using high-resolution land-use proxies from different datasets for Kyoto accounting in a data-rich case study region in Germany.
