Lal","doi":"10.2489/jswc.2023.0106A","DOIUrl":"https://doi.org/10.2489/jswc.2023.0106A","url":null,"abstract":"T he Sahara Desert, a vast, seemingly empty land mass covered with sand or sand dunes with sparse, if any, scrub vegetation, covers an area of 9.4 × 106 km2 (3.63 × 106 mi2) (Abotalib et al. 2016). Sahara is a feminine name based on an Arabic word sahrā or “desert.” It extends from Atlantic Ocean in the west to the Red Sea Hills in the east, and from Mediterranean Sea in the north to the Sahel Zone in the south. Because of the arid climate, average annual precipitation of less than 5 mm (0.2 in) (New et al. 2000), and harsh environments, agriculture traditionally has been confined to specific areas called oases (small patches of vegetation fed by a spring and surrounded by desert). Thus, the African continent, where the Sahara Desert is located, is characterized by the familiar bleak statistics, such as 300 million people without access to safe drinking water and only 5% of arable land being irrigated (Tornhill 2012). Furthermore, prevalence of undernourishment in Africa (the percentage of the total population prone to lack of access to safe and healthy food) has been on the rise and was 44.4% in 2014, 49.7% in 2016, 51.3% in 2018, 52.4% in 2019, and 56.0% in 2020. Of this, prevalence of severe undernourishment (percentage of total population) was 16.7% in 2014, 19.2% in 2016, 19.3% in 2018, 31.9% in 2019, 32.2% in 2020, and 34.4% in 2021 (FAO et al. 2022).The problem of food insecurity is presumably aggravated by the current and projected increase in population, especially that of sub-Saharan Africa. The populations of Europe and North America combined (1.18 billion) and that of sub-Saharan Africa (1.2 billion) were similar in 2022. However, the rate of increase in population has been less than 1% in Europe and North America since the 1960s and is reaching the level of zero growth in 2020 and Rattan Lal is a distinguished university professor of soil science and is director of the CFAES Rattan Lal Center for Carbon Management and Sequestration, The Ohio State University, Columbus, Ohio. Received January 6, 2023. 2021 (UN 2022). In comparison, the annual rate of population growth in subSaharan Africa peaked at 3% in 1978 and remained above 2.8% in the 1980s; it is now the region with the fastest growing population, which is projected to double by 2040 (UN 2022). Similar to the historic concerns about South Asia and China, there are many discouraging questions: Who will feed Africa? Can Africa feed itself? Are there enough natural resources to feed the growing population?” In the final analysis, it is Africa that will feed its population, and it has natural resources to do so (Muang and Andrews 2014). Instead, it is a question of when its policy makers will create environments (pro-nature, pro-farmers, pro-agriculture, and pro-innovations) that translate known science into action (World Bank 2012). It is precisely in this context that recent agricultural progress in the Sahara is an important indication that Africa has an abundance of water (even ","PeriodicalId":50049,"journal":{"name":"Journal of Soil and Water Conservation","volume":"256 1","pages":"57A - 62A"},"PeriodicalIF":3.9,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82799650","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Perkins","doi":"10.2489/jswc.2023.00022","DOIUrl":"https://doi.org/10.2489/jswc.2023.00022","url":null,"abstract":"Salt-impacted soils are formed through anthropogenic or natural causes. In the northern Great Plains region of North America, salts that occur in the soil parent materials move upward through the soil profile due to changing land-use and precipitation regimes. If these salts accumulate in the surface soil layer, they impact the ecological integrity of a site, creating the need for ecological restoration. Common methods for addressing salt-impacted soil were developed in the irrigated soils of the southwestern United States and are often ineffective in noncrop areas and the northern Great Plains due to differences in soil properties, elevated gypsum concentrations, and poor soil drainage. Therefore, the objective of this study was to identify native plant species suited for revegetation in salt-impacted soils in the northern Great Plains region of North America. This field study evaluated the survival and performance of eight native plant species in soils with high, medium, or low salt concentrations. Survival was evaluated at summer and end-of-season sampling (five months total) and performance variables (plant height, basal diameter, number of flowering heads, number of tillers/stems, and aboveground biomass) were evaluated at end-of-season sampling. Seven of the eight species evaluated exhibited some salt tolerance and could be suitable for the revegetation of moderately salt-impacted soil. Overall, <i>Asclepias speciosa, Gaillardia aristata</i>, and <i>Helianthus maximiliani</i> grew in minimally salt-impacted soils, whereas <i>Elymus canadensis, Elymus trachycaulus</i>, and <i>Pascopyrum smithii</i> grew in moderately salt-impacted soils, and only <i>Sporobolus airoides</i> grew in highly salt-impacted soils. As these native plants establish and grow, they will spur autogenic recovery by stabilizing soil structure and improving water movement in the soil. These results indicate that salt tolerance must be considered when selecting species that could revegetate these areas.","PeriodicalId":50049,"journal":{"name":"Journal of Soil and Water Conservation","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135711916","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Following the passing of the Clean Water Act in the 1970s, total phosphorus (P) loading to the lake substantially decreased through permitting of point sources and through conservation efforts to decrease sediment loss from agricultural fields. While total P losses to Lake Erie have remained relatively stable since the 1990s, dissolved P has increased and resulted in increases in the extent and severity of algal blooms over the past two decades (Smith et al. 2015b). Both agricultural industry and environmental quality are vital to local and regional economies.

In this study, we documented the process of NRS formulation and implementation by states based on qualitative interviews with 34 policy actors involved with NRS development in seven Upper MRB states a decade after the NRS framework was introduced. Our objectives were to (1) describe and compare stakeholder perceptions of each state’s NRS policy stages; (2) identify common challenges, accomplishments, and innovations resulting from the NRSs; and (3) explore the role of the 2011 USEPA memo as a catalyst for nutrient reduction action. We found that the USEPA policy memo was generally acknowledged as a catalyst for initial planning, but most interviewees framed the policy problem primarily around concern for local waterways compared to the Gulf of Mexico as a motivation for sustained policy development and implementation. Multistakeholder forums were a commonly cited success of the NRS development processes. Implementation challenges included the voluntary nature of most options to address nonpoint source pollution and the scale of practice implementation needed to achieve goals. There were differences both within and among states with respect to the importance and effectiveness of one USEPA framework element—establishing numeric nutrient criteria.","PeriodicalId":50049,"journal":{"name":"Journal of Soil and Water Conservation","volume":"54 1","pages":"70 - 81"},"PeriodicalIF":3.9,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89295524","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
