“…The identification of irrigable land that is close to the water supply (rivers) was done by calculating the straight-line (Euclidean) distance from the streams that is generated from a 20m x 20m cell size DEM in a GIS tool and then reclassifying. The land which is nearest to the stream was considered the most suitable land for irrigation development and the land which is far from the stream is slightly suitable (Birhanu et al 2019;Worqlul et al 2015).…”

Ethiopia is endowed with immense water and land resources that could be tapped and used for irrigation development. However, little has been done so far due mainly to lack of comprehensive knowledge on the potential of these resources. This study was, therefore, taken up to assess the irrigation potential in data scarce Jewuha watershed of the Awash River Basin. To achieve the objective of the study, the suitability of the land for both surface and pressurized irrigations was estimated using a parametric evaluation technique combined with the FAO land evaluation framework in the GIS environment with multi-criteria analysis of irrigation suitability factors. The irrigation water demands of major crops adopted in the area were determined using CROPWAT software. The surface water potential at the sub watershed was estimated using a combination of SWAT model and the spatial proximity regionalization technique. The performance of the SWAT model was checked by statistical parameters. The irrigation suitability analysis reveals that 51372ha of the study area are suitable and 16274ha are unsuitable for surface irrigation system. Furthermore, 52768ha of the area are suitable and 15088ha are unsuitable for a sprinkler irrigation system. For drip irrigation, 52751ha are suitable and 14855ha are unsuitable. The calibration and validation of SWAT model showed that the model has performed well to simulate the hydrology of the watershed with a coefficient of determination (R2), Nash-Sutcliffe efficiency (NSE) and Percent of bias (PBIAS) of 0.74, 0.73 and 0.80 for calibration and 0.71, 0.70 and 7.90 for validation, respectively. From a combined analysis of the available land and water resources, the gross irrigation potential of the area is estimated to be 12,997ha, of which 3098ha of land is exclusively suitable for surface irrigation and 9,899ha is suitable for pressurized irrigation systems.

Sustainable development is one of the ubiquitous paradigms of this century. Poverty, biodiversity loss and climate change are some of the obstacles to achieving sustainable development. To mitigate these encumbrances, countries have painstakingly adopted various policies and interventions. Public work programs, one of the initiatives targeting the construction of strong social safety nets through redistribution of wealth and generation of meaningful employment are increasingly being launched in developing countries. This paper is an attempt to examine the effects of phased implementation of Mahatma Gandhi National Rural Employment Guarantee Scheme (MGNREGS) on the rejuvenation and restoration of community forests in India. Searches performed in multidisciplinary electronic databases (Web of Science, Scopus, Science Direct, PubMed, Emerald Insight, Google Scholar, Taylor and Francis Online, Wiley Online Library, and Springer Link) indicated that MGREGS is one of the largest labor guarantee schemes ever recorded in India and globally, and has holistically contributed to reforestation and afforestation through its land development themes to reduce vulnerability of rural communities to recurrent droughts, floods and improve soil moisture and fertility. It is evident that MGNREGS in synergy with the government forest development programs have the potential to promote social afforestation, reforestation and biodiversity conservation as witnessed in the Sundarbans. These have the potential to empower local people through creation of income generating activities and provision of local forest goods and services. However, the creation of forests as rural assets necessitates that emphasis should be laid on their maintenance so as to ensure that they are given their due importance for sustainable and long-term benefit of the poor rural households. This study highlights the need to perform a comprehensive assessment of forest assets that has been established through MNREGS across states in India.

“…To ensure better management of the land and water resources, to assist irrigation system planning and design of irrigation systems, a well-developed database is essential. To this end, the geographic information system (GIS) techniques can easily be employed to establish the required database in the form of maps and attribute tables (Kumar, Yamaç, & Velmurugan, 2015;Birhanu et al, 2019). GIS makes it possible to collect, store, manipulate, and extract spatial data.…”

In this study, an assessment of the land and surface water resources potential of the Becho Plain was conducted. Land suitability for irrigated agriculture was evaluated by considering the Food and Agriculture Organization (FAO) criteria. The land suitability parameters such as soil properties, slope, land use and land cover were used to identify the suitable irrigable land. The analytical hierarchy process was employed to obtain parameter weights, and later the weighted overlay analysis in the geographic information system was employed to obtain the overall suitability of land resources for irrigation. The surface water availability and amount were evaluated by using the calibrated Soil and Water Assessment Tool (SWAT) model. The water requirement of dominant crops was estimated following the FAO procedure and compared with the available water. Nearly 70% of the land area is identified as suitable for surface irrigation, while the remaining 30% of the land area is restricted for irrigation development. The water supply and demand analysis revealed that there is sufficient water available in the Becho Plain for irrigation development. The physically possible irrigation area and diversion sites were also identified. The Becho Plain has ample land and water resources for irrigation development.However, future developments shall also consider downstream water use to implement sustainable irrigation development.
