Local-scale opportunities to address challenges of the water–food nexus in the developing world need to be embraced. Borehole-garden permaculture is advocated as one such opportunity that involves the sustainable use of groundwater spilt at hand-pump operated borehole supplies that is otherwise wasted. Spilt water may also pose health risks when accumulating as a stagnant pond. Rural village community use of this grey-water in permaculture projects to irrigate borehole gardens is proposed to primarily provide economic benefit whereby garden-produce revenue helps fund borehole water-point maintenance. Water-supply sustainability, increased food/nutrition security, health protection from malaria, and business opportunity benefits may also arise. Our goal has been to develop an, experience-based, framework for delivery of sustainable borehole-garden permaculture and associated benefits. This is based upon data collection and permaculture implementation across the rural Chikwawa District of Malawi during 2009–17. We use, stakeholder interviews to identify issues influencing uptake, gathering of stagnant pond occurrence data to estimate amelioration opportunity, quantification of permaculture profitability to validate economic potential, and critical assessment of recent permaculture uptake to identify continuing problems. Permaculture was implemented at 123 sites representing 6% of District water points, rising to 26% local area coverage. Most implementations were at, or near, newly drilled community-supply boreholes; hence, amelioration of prevalent stagnant ponds elsewhere remains a concern. The envisaged benefits of permaculture were manifest and early data affirm projected garden profitability and spin-off benefits of water-point banking and community micro-loan access. However, a diversity of technical, economic, social and governance issues were found to influence uptake and performance. Example issues include greater need for improved bespoke garden design input, on-going project performance assessment, and coordinated involvement of multi-sector governmental-development bodies to underpin the integrated natural-resource management required. The developed framework aims to manage the identified issues and requires the concerted action of all stakeholders. Based on the probable ubiquity of underlying issues, the framework is expected to be generalizable to the wider developing world. However, this particular application of permaculture represents a fraction of its greater potential opportunity for rural communities that should be explored.

This paper describes tools and lessons learned in operationalizing the principles of good local water governance and mult ple- use water services for food security in mid- and far-western Nepal. In these poor, water-scarce and food-insecure regions, the Rural Village Water Resources Management Project has shown that integrated water resources management for both blue and green water is a must. Water use master plans (WUMPs) and a participatory step-by-step approach, both backed up by a gender equality and social inclusion (GESI) strategy, ensure appropriate and fair use of scarce water resources. Multiple-use water services (MUS) maximize livelihoods opportunities in a difficult environment.

Environmental pollution and food safety are two of the most important issues of our time. Soil and water pollution, in particular, have historically impacted on food safety which represents an important threat to human health. Nowhere has that situation been more complex and challenging than in China, where a combination of pollution and an increasing food safety risk have affected a large part of the population. Water scarcity, pesticide over-application, and chemical pollutants are considered to be the most important factors impacting on food safety in China. Inadequate quantity and quality of surface water resources in China have led to the long-term use of waste-water irrigation to fulfill the water requirements for agricultural production. In some regions this has caused serious agricultural land and food pollution, especially for heavy metals. It is important, therefore, that issues threatening food safety such as combined pesticide residues and heavy metal pollution are addressed to reduce risks to human health. The increasing negative effects on food safety from water and soil pollution have put more people at risk of carcinogenic diseases, potentially contributing to ‘cancer villages’ which appear to correlate strongly with the main food producing areas. Currently in China, food safety policies are not integrated with soil and water pollution management policies. Here, a comprehensive map of both soil and water pollution threats to food safety in China is presented and integrated policies addressing soil and water pollution for achieving food safety are suggested to provide a holistic approach.

This study aims at analyzing the impact of water and soil conservation strategies on households? food security in the North-western part of Benin. It was conducted in the municipalities of Boukombé and Ouaké. Three villages were studied. From random way, 180 producers were investigated. The causes of soil degradation, water and soil conservation strategies, available food supply and food consumption frequency were collected. Degradation factors were analyzed using discourse analysis and prioritized using the Friedman test. Food supply and frequency of consumption were compared between beneficiaries and non-beneficiaries of the projects using the Student t test. Land degradation is caused by socio-cultural factors (overexploitation of lands, trees? cutting, late bush fires, grazing, agroforestry and monoculture) and natural factors (heavy rains and steep gradient of the soils). The first three factors are respectively the exploitation of land, trees? cutting and late bush fires practice in both towns. Food reserves before the new crops were not affected by exogenous strategies released by the erosion control projects. But the frequency of food consumption is improved statistically among project beneficiaries than non-beneficiaries. This confirms the theory of Boserup | E Janvier et al., 'Impacts of water and soil conservation strategies on households? food security in North West of Benin', International Journal of Agricultural Science Research, vol. 3(10), pp.196-202, Academe Research Journals, 2014

The summary and the conclusions presented here are based on the results of four case studies, three for drinking water and one for soil and water conservation. The cases were selected from the projects under the Sino-German IESP ("Integriertes Ernaehrungssicherungsprogramm"; Integrated Food Security Programme) in Shandong, People's Republic of China. The aim of the study was to do an economic analysis of the selected cases, in order to answer questions about the sustainability ofthe projects' benefits. The selected drinking water projects include the deep well in Quanziyu village, the big-mouth well in Mawo, and the cisterns in Xiyu. The projects vary in technology, age, and village context (e.g. village size and wealth). The soil and water conservation project covers the whole water catchment area around Mawo village. All projects are located in the county of Pingyi, except for Xiyu, which belongs to Yishui county. In the section A, the main results and conclusions from the drinking water case studies are presented. After a brief introduction, the main findings are explained in general. Next, the situation of each project, as related to costs and water charges, is described in more detail. Finally, an overview of the results from the benefit analysis is given. The section B deals with the main results and conclusions concerning the soil and water conservation project. The results from the financial appraisal of all project components taken together are summarised, before the individual components are described separately.

Functioning of polymetallic factories are considerable harming the ecological systems in the environment. Operation of RMG Gold and Copper Mine in the SE part of Georgia causes severe ecological problems in the region. It is vital that conducted monitoring near the areas where industrial activities are underway. The study is aimed at eco-monitoring of the Bolnisi municipality, Georgia. The monitoring was conducted of heavy metals (Cu, Zn, Cd) in system “water-soil-plant” in the area of Kazreti (Madneuli) – villages: Balichi, Ratevani, Naxiduri, Xidiskhuri. According to the results obtained in the soil, content of heavy metals are significantly higher than the allowable concentration limit. In spite of this in crops of the plants which were grown on this soil, content of Cu and Zn does not exceed the allowed concentration limits, Cd content was not found. Study plants were green been, mauhroom, green walnut, green pepper, cucumber, cherry, potato, tomato, walnut, garlic, dry been and corn. Study water were rivers Kazretula and Mashavera's water. Rivers Kazretula and Mashavera water content Zn and Cd concentration.
