Exploring land use/land cover changes, drivers and their implications in contrasting agro-ecological environments of Ethiopia

Peer-reviewed publication
Agosto, 2019
Etiopía

This study examined the trends, driving factors, and implications of land use/land cover (LULC) dynamics over the past 35 years (1982–2017) in three watersheds of the drought-prone areas that represent different agro-ecologies of Upper Blue Nile basin, Ethiopia: Guder (highland), Aba Gerima (midland), and Debatie (lowland). The changes in LULC were analyzed by integrating field observations, remote-sensing data (aerial photographs [1: 50,000 scale] and very high resolution [0.5–3.2 m] satellite images), and geographic information systems.

Principles and Applications of the Global Human Settlement Layer as Baseline for the Land Use Efficiency Indicator—SDG 11.3.1

Reports & Research
Enero, 2019
Global

The Global Human Settlement Layer (GHSL) produces new global spatial information, evidence-based analytics describing the human presence on the planet that is based mainly on two quantitative factors: (i) the spatial distribution (density) of built-up structures and (ii) the spatial distribution (density) of resident people. Both of the factors are observed in the long-term temporal domain and per unit area, in order to support the analysis of the trends and indicators for monitoring the implementation of the 2030 Development Agenda and the related thematic agreements.

Improved drought detection to support crop insurance models: powerpoint

Conference Papers & Reports
Mayo, 2018

Anomaly assessment for drought monitoring, as required for index insurance applications, is commonly done by comparing actual NDVI measurements against their historical records on a pixel-by-pixel basis. Limited years of satellite records with operational real-time availability result in time-series with a relative low count in annual repeats, e.g., the VEGETATION sensor onboard SPOT and Proba-V has completed at present only 19 full annual repeats. This number is too low for agricultural index insurance models that require accurate assessments of impacts of perils (e.g.

Predicting Land Use Changes in Philadelphia Following Green Infrastructure Policies

Peer-reviewed publication
Enero, 2019
Estados Unidos de América

Urbanization is a rapid global trend, leading to consequences such as urban heat islands and local flooding. Imminent climate change is predicted to intensify these consequences, forcing cities to rethink common infrastructure practices. One popular method of adaptation is green infrastructure implementation, which has been found to reduce local temperatures and alleviate excess runoff when installed effectively. As cities continue to change and adapt, land use/landcover modeling becomes an important tool for city officials in planning future land usage.

Analysis of High Temporal Resolution Land Use/Land Cover Trajectories

Peer-reviewed publication
Enero, 2019
Brasil

In this study, methods, originally developed to assess life course trajectories, are explored in order to evaluate land change through the analysis of sequences of land use/cover. Annual land cover maps which describe land use/land cover change for the 1985–2017 period for a large region in Northeast Brazil were analyzed. The most frequent sequences, the entropy and the turbulence of the land trajectories, and the average time of permanence were computed. Clusters of similar sequences were determined using different dissimilarity measures.

Land in the Proposed Constitution of Kenya: What does it mean?

Reports & Research
Mayo, 2010
Kenya
África

Covers what is ‘land’ and what ‘property’ in the proposed Constitution?; where is land covered; common questions…with some answers; what does the proposed Constitution actually say and not say about land?; so what is the verdict? Concludes that it opens the door to significant reforms and failure to perform could be a matter of challenge in the courts. Ordinary Kenyans will need to hold the State to account in devising appropriate legislation and programmes swiftly and with the maximum of public participation.

Effects of land use change on streamflow and stream water quality of a coastal catchment

Reports & Research
Enero, 2017
Sudáfrica

This study aimed to link land cover/use change to water quality in an important water supply coastal catchment. The approach followed a spatial and temporal analysis of historical catchment land use change to assess how changes influenced water quality and river flow in the Touws and Duiwe Rivers, southwestern Cape, South Africa. Each sub-catchment has unique characteristics which influence land use and water quality and the purpose was to analyse each one separately.

Expropriation Bill [B4-2015]: public hearings with Deputy Minister in attendance Day 2

Legislation & Policies
Julio, 2015
Sudáfrica

Agri SA supported orderly land reform – equitable land distribution is a prerequisite for rural stability and inclusive rural development. Agri-SA believed that expropriation should only be used as a last resort where negotiations fail. There needed to be a clear purpose for expropriation. Compensation should never be dependent on the state’s ability to pay. The land owner should always be afforded recourse to the courts to contest both the merits of the expropriation and the compensation amount.

Department of Rural Development and Land Reform; Ingonyama Trust; Commission on Restitution of Land Rights on their 2014/15 Annual Reports; Audit outcomes by Auditor-General

Legislation & Policies
Octubre, 2015
Sudáfrica

A representative of the Auditor-General South Africa (AGSA) briefed the Committee on the audit outcomes and expenditure patters in the rural development portfolio for the 2014/2015 financial year. The quality of submitted financial statements for the Agricultural Land Holding Account (ALHA) was good but needed improvement. The quality of submitted performance reports for Ingonyama Trust Board (ITB) was good but required intervention from the Department of Rural Development and Land Reform (DRDLR or the Department).

Water-use accounts in CPWF basins: Simple water-use accounting of the São Francisco Basin

Reports & Research
Diciembre, 2010
Brasil
América del Sur

This paper applies the principles of water-use accounts, developed in the first of the

series, to the São Francisco basin in South America. The São Francisco Basin lies wholly

within Brazil. There are several major dams and wetlands in the Basin.

Net runoff is about 16% of total precipitation. Grassland is the most extensive land use,

covering 59% of the Basin and uses 48% of the water. Rainfed agriculture covers 23%

of the basin, but uses 14% of the water in the Basin. Forest and woodland cover 16% of

Water-use accounts in CPWF basins: Simple water-use accounting of the Karkheh Basin

This paper applies the principles of water-use accounts, to the Karkheh River basin in Iran.

The northern part of the Basin where the Karkheh and its tributaries rise is mountainous, cooler, and wetter. The River spills out on to the hotter, lower semi-arid plains at its southern end. Precipitation, mainly in winter, varies from 400-500 mm in the upper part of the Basin falling to about 230 mm in the lower reaches.
