An Analysis of Water Awareness Campaign Messaging in the Case of Jordan: Water Conservation for State Security
(2019-06-01)
This article examines water awareness campaign messaging of the Water Efficiency and Public Information for Action (WEPIA) campaign. Using Jordanian government documents and structured interviews, it argues that the Ministry of Water and Irrigation (MWI) promotes water awareness campaigns to shape water users’ habits and perspectives on water. The goal of this strategy is to align popular concerns about water security with government concerns over state security, i.e., to create responsible water citizens. This article ...

Effect of Sowing Method and Weed Control on the Performance of Maize (Zea mays L.) Intercropped with Climbing Beans (Phaseolus vulgaris L.)
(2017-06-23)
Maize is grown on a large area in Germany and there is a growing concern in society about negative environmental effects related to this. The objective of the study was to test the performance of mixtures of maize and climbing beans as an alternative to monocropped maize under different site and management conditions. The effects of sowing density of maize and beans as well as the sowing time of beans on total dry matter (DM) yield and bean DM contribution to the total yield were investigated. Further, various ...

Nutritional Comparison of White and Red Coccinia Abyssinica (Lam.) Cong. Accessions: An Under-Utilised Edible Tuber of the Ethiopian Highlands
(2017-08-22)
Anchote (Coccinia abyssinica) is an indigenous tuber crop of the Ethiopian Highlands. It is popular in the western Oromia Region of the country. Apart from food, the crop is also used in traditional medicine. Anchote tubers possess two variations in its tissue colour, red and white. In this study, a small market survey and a nutritional comparison of red and white anchote were conducted. White tissue anchote seems to be more popular, due to its soft texture and ease of cooking. However, the red variant was considered ...

Superfruit in the Niche - Underutilized Sea Buckthorn in Gilgit-Baltistan, Pakistan
(2019-10-21)
Sea buckthorn is a medicinal plant occurring throughout the temperate regions of the northern hemisphere. Considered as a “superfood” given the nutritional properties of its berries, the latter have a large international market potential, particularly in China and Europe. Although sea buckthorn grows widespread in northern Pakistan, it is a neglected species there. Fruit marketing is severely hampered by low raw product quality, varying prices, and low local demand. During 2017–2018 a total of 111 collectors and 17 ...

Application of Arthrospira (Spirulina) platensis against Chemical Pollution of Water
(2019-08-23)
The basis of phytoremediation technology for cleaning chemically polluted water was developed in the framework of the presented work. This technology is based on the ability of blue-green alga Arthrospira platensis to eliminate different environmental toxicants from water. This technological approach was conducted for the following pollutants: 1,1,1-trichloro-2,2-bis(4-chlorophenyl)ethane (DDT), 2,4,6-trinitrotoluene (TNT), and cesium ions. The effectiveness of the technology was tested in model experiments, which ...

An interdisciplinary assessment of private conservation areas in the Western United States
(2020-02-20)
Conservation easements are the fastest growing private conservation strategy in the United States. However, mechanisms to assess private land conservation as well as their support by the general public are not well understood. This study uses the ecosystem services framework for assessing existing private lands in Idaho and identifies areas for future conservation easements. Using conservation targets of the land trust as a guide for selecting ecosystem services, we (a) mapped the spatial delivery of conservation ...

Morphological and Genetic Diversity of Sea Buckthorn (Hippophae rhamnoides L.) in the Karakoram Mountains of Northern Pakistan
(2018-07-30)
Sea buckthorn (Hippophae rhamnoides L.) is a dioecious, wind-pollinated shrub growing in Eurasia including the Karakoram Mountains of Pakistan (Gilgit-Baltistan territory). Contrary to the situation in other countries, in Pakistan this species is heavily underutilized. Moreover, a striking diversity of berry colors and shapes in Pakistan raises the question: which varieties might be more suitable for different national and international markets? Therefore, both morphological and genetic diversity of sea buckthorn ...

Multi-Temporal Agricultural Land-Cover Mapping Using Single-Year and Multi-Year Models Based on Landsat Imagery and IACS Data
(2019-06-12)
The spatial distribution and location of crops are necessary information for agricultural planning. The free availability of optical satellites such as Landsat offers an opportunity to obtain this key information. Crop type mapping using satellite data is challenged by its reliance on ground truth data. The Integrated Administration and Control System (IACS) data, submitted by farmers in Europe for subsidy payments, provide a solution to the issue of periodic field data collection. The present study tested the ...

Estimation of Vegetable Crop Parameter by Multi-temporal UAV-Borne Images
(2018-05-22)
3D point cloud analysis of imagery collected by unmanned aerial vehicles (UAV) has been shown to be a valuable tool for estimation of crop phenotypic traits, such as plant height, in several species. Spatial information about these phenotypic traits can be used to derive information about other important crop characteristics, like fresh biomass yield, which could not be derived directly from the point clouds. Previous approaches have often only considered single date measurements using a single point cloud derived ...

Farmers’ Perception of Water Quality and Risks in the Mashavera River Basin, Georgia: Analyzing the Vulnerability of the Social-Ecological System through Community Perceptions
(2018-08-28)
Competing natural resources usage that leads to dramatic land use changes can threaten the balance of a social-ecological system. When this is the case, communities are directly exposed to the negative consequences of those land use changes. The Mashavera River Basin is considered one of the hotspots of environmental pollution in Georgia. This is of importance for public health because the food production from this basin meets a substantial proportion of the country’s food demand. The farmers’ perception of the water ...
