From the perspective of national food security, strengthening domestic rice production is an urgent issue for Kenya. For this purpose, it is helpful to consider varieties that generate novel and competitive values different from those of conventional varieties. Recently, domestic japonica rice, which is now being distributed, has become an attractive variety with a high market price and its production is expected to increase. Although it is competitive and promising as a crop for small-scale farmers, the production stage costs and benefits are not clear. Thus, a study was conducted to perform a cost–benefit analysis of japonica rice in comparison to conventional rice at the production stage and evaluate strategies for strengthening the domestic production of rice. We conducted an experimental cultivation of japonica rice in the Mwea region, Kenya, where japonica rice is produced. As a result, although production costs for japonica rice are higher than costs for conventional varieties (24.46 KSh/kg versus 22.63 KSh/kg), when a high-yielding variety is grown (6.44 tons/ha for japonica rice compared to 6.07 tons/ha for conventional rice), a larger net profit can be obtained (65.54 KSh/kg versus 32.37 KSh/kg). We believe that initiatives to improve difficulties at the production stage would make the production of both japonica rice and conventional rice more economically viable and facilitate strengthening of the overall domestic rice production.

Modern dietary habits in communities are linked and are part of the global food supply chain. To achieve sustainable food production and consumption, communicating the impact associated with food production and dietary choices at community level to consumers is important. However, previous footprint studies have primarily focussed on food consumption at the national level and neglected community–level consumption activities. This study surveyed the diets of a small island community and linked the results with multi-region land footprint analysis in Ollei Village, Republic of Palau. The analysis was used to determine the extent to which the dietary lifestyles of communities depend on external land use through the global supply chain. We showed that the global food supply chain has reached this corner of the world, and the dietary habits of the community are already heavily dependent on processed and imported foods. The community and country are highly dependent on large land use in some major producer/exporting countries through the global food supply chain. In addition, the amount of external land used for food production exceeds the biocapacity of the agricultural land in the community and country. This study bridges the gap between community–level consumption activities and national-scale footprint analysis, and quantitatively assesses the impact of consumption activities at the community level on the global environment. The results and approach of this study could contribute to the development and implementation of vertically integrated food policies between the national and community level in Palau.

Understanding the effects of local knowledge on actions and decisions taken during a crisis is important; empirical studies and scientific data can be instructive to this end. This study integrated local knowledge (Pranata Mangsa) in Jawa, Indonesia, with scientific data on diurnal rainfall, extreme precipitation events, using the Local and Indigenous Knowledge System (LINKS). The results showed that Pranata Mangsa has informed aspects of agriculture including crop calendars, crop patterns, and farming activities, for over 1000 years in Jawa. Pranata Mangsa also enhances community resilience by mitigating the effects of extreme droughts; this finding was validated using scientific data.

Thailand plays a central economic and policy-making role in Southeast Asia. Although climate change adaptation is being mainstreamed in Thailand, a well-organized overview of the impacts of climate change and potential adaptation measures has been unavailable to date. Here we present a comprehensive review of climate-change impact studies that focused on the Thai water sector, based on a literature review of six sub-sectors: riverine hydrology, sediment erosion, coastal erosion, forest hydrology, agricultural hydrology, and urban hydrology. Our review examined the long-term availability of observational data, historical changes, projected changes in key variables, and the availability of economic assessments and their implications for adaptation actions. Although some basic hydrometeorological variables have been well monitored, specific historical changes due to climate change have seldom been detected. Furthermore, although numerous future projections have been proposed, the likely changes due to climate change remain unclear due to a general lack of systematic multi-model and multi-scenario assessments and limited spatiotemporal coverage of the study area. Several gaps in the research were identified, and 10 research recommendations are presented. While the information contained herein contributes to state-of-the-art knowledge on the impact of climate change on the water sector in Thailand, it will also benefit other countries on the Indochina Peninsula with a similar climate.

Small hydropower plants utilizing unharnessed energy in existing irrigation systems are a prominent source of renewable energy. In Japan, land improvement districts play a key role in the management of irrigation systems, but face serious problems in terms of management sustainability and require participation from non-farmers. The purpose of this study was to examine the effect of residents’ involvement in small hydropower projects on their environmental awareness and understanding of the projects’ multifunctional regional value. We administered a questionnaire survey to 238 households in three areas: Itoshiro, Kashimo and Ibigawa. The respondents were categorized into four groups: participation, recognition, knowledge and control. Based on the degree of respondents’ involvement in small hydropower projects, inclusive relationships between their involvement and awareness were revealed. These relationships suggest that the trigger of resident involvement is a key factor in developing sustainable small hydro facilities within existing irrigation systems.

In this research, power generation potential is estimated using overflow discharge for eight headworks (Inuyama, Meiji-yousui, Muromatsubara, Kansakawa, Furikusa, Onyu, Hosokawa and Okajima) located in Aichi and Gifu Prefectures, and the characteristics of their power generation are clarified in order to evaluate the feasibility of small hydropower plants. The results are as follows. Firstly, overflow discharge is more stable than the discharge of intake water at the headworks, which suggests that power generation using overflow discharge is more suitable for actual power generation. Secondly, maximum power outputs of 43 kW to 2,002 kW, under a discharge utilization factor of 60%, show great potential for power generation at these eight headworks. Finally, fluctuations in monthly power generation are higher than that of annual power generation due to the influences of irrigation and seasonal changes in precipitation on water intake.

Land resources are essential for humans to survive, and different methods of land- resource use depend largely on the local natural context and society. Here we propose a method to assess land-resource use in terms of efficiency and sustainability for three historical types of land- resource use in the Babeldaob Islands, Republic of Palau: self-supply, resource development and nature conservation. Our proposed index of land-use efficiency makes comparisons possible among the types of land-resource use, considering both the natural and social conditions; land-use efficiency increased in the order of self-supply, nature conservation and resource development. At the same time, sustainability of land-resource use corresponded to population growth; when the population density was less or more than 15 capita km-2, self-supply and nature conservation were the most sustainable, respectively.

The suspended sediment load in river water is an important index for the soil erosion rate in the watersheds of designated rivers. Amongst the various methods for estimating the suspended sediment load, the most frequently used one is the sediment rating curve. The sediment rating curve can aid in the understanding of the relationship between the behaviour of the suspended sediment transport and the discharge flow for estimating soil erosion. However, the rating curve tends to underestimate the actual values of both the suspended sediment load and the suspended sediment concentration during high discharge and to overestimate them during low discharge. The aim of the present paper is to confirm how to use the sediment rating curve to estimate soil erosion under its limitations and benefits. The accuracy of sediment rating curve is affected by various factors, including seasons, discharge stages, catchment area, and sampling frequency. In many cases, it cannot be concluded easily that sediment rating curve is the best method to estimate suspended sediment load. At the same time, there is no other method that is simple and commonly used for the estimation of suspended sediment load, as the sediment rating curve. Efforts on the improvement of the sediment rating curve, such as data separation among the seasons and the increasing of sampling frequency, are needed for the better estimation as well as the accuracy of suspended sediment load.

Vientiane, Lao PDR, has been subject to extensive and ongoing urbanization plans, including development of natural marshes and residentialization of paddy fields into suburban areas, despite natural marshes playing a vital role in treating wastewater from urban areas. Therefore, it is important to understand the current situation regarding the nutrient balance in these natural wastewater treatment systems to predict future conditions and design appropriate measures against water quality deterioration. However, limited data are available in Vientiane on the hydrological characteristics of water and nutrient runoff that flow into marshes through drainage canals. In this study, we conducted a periodic survey of drainage canals and Mak Hiao River in the wastewater catchment system surrounding Vientiane during the rainy and dry seasons. We monitored the discharge of surface water at 21 observation sites and analyzed water quality of nitrogen, phosphorus, and total organic carbon. These observations revealed that the concentrations of dissolved nitrogen and phosphorus were significantly higher at sites in urban areas, followed by sites in the main river basin and those in agricultural areas. Dissolved nitrogen and phosphorus concentrations varied with runoff discharge, especially in urban and river basin sites, with lower concentrations in the rainy season and higher concentrations in the dry season. On the other hand, we found no significant differences between the rainy and dry seasons in nutrient concentrations in the agricultural basin. Finally, we proposed measures to counteract the deterioration of water quality during dry seasons and simulated the impact of these measures.

Japan is facing a severe problem with the aging of its infrastructure, including dams. We studied eight controversial cases (the Ararse, Okusawa, Setoishi, Tamayodo, Minochi, Yasuoka, Tsuga and Nibutani Dam) involving dam removal in Japan and elucidated the triggers and suggested reasons for the debate. Renewal of water rights was a major trigger in three of the eight cases. Environmental reasons in five cases were not relevant to the demolition decision regarding dams conferring public benefit, even if restoration of the river environment was a recognized benefit. Compared with single‐purpose dams, the removal debate for a multi‐purpose dam, based on economic reasons regarding a single function, did not gain traction. Among the eight cases, there has been no case triggered by the renewal of water right by reason of economics, which should be highlighted options for stock management purposes.

Water deficit is a problem on rainfed maize production but can be solved by proper land management. The objective of the study to determine the soil physical properties and maize yield affected by land management to adapt to drought. The experimental design was a randomized complete block using 5 treatments with 4 repetitions, including: (i) Control (KO), (ii) Rice Straw Mulched (MC), (iii) Compost Fertilizer (CF), (iv) In-Organic Fertilizer (AF), (v) Legume Cover crop (CC). Soil physical and maize growth properties namely soil moisture, soil texture, soil bulk density, plant height, biomass, and yield were investigated. The results showed that composting land increased soil water availability and provided nutrient to crops and thus increase soil physical properties, maize growth and yield. Although inorganic fertilizer also increased plant growth and yield, but it did not improve soil physical properties.

Water resource management on a watershed-scale becomes crucial to cope with expected water shortage in the future. One of the key factors in water resource management is forest management, since forest cover changes have large impacts on hydrological processes on watershed scale. Afforestation, forest thinning, clear-cutting and tree species conversion are the most common techniques of forest cover managements. Though it is essential for water resource management, how the forest cover management impacts on hydrological processes has not been systematically understood. Thus, we reviewed the effects of the above four technics in forest cover management on the runoff characteristics from various watersheds in the world. Afforestation is not suitable for countries with a little precipitation because mature forests can reduce much amount of runoff. On the other hands, planting trees in the upland part of the catchment can reduce the flood risk in the downstream area. Thinning and clear cutting can increase the amount of runoff, but at the same time, can decrease the water quality of streamflow. Converting natural/secondary forests to a single plant forest strongly decreases the total amount of runoff. The broadleaf deciduous can produce higher annual runoff but control flood discharge than evergreen coniferous forest. To replace pine trees with eucalyptus for forest plantation has a positive effect on the total amount of timber that can be produced but has a huge impact in decreasing water resource, because of high water consumption of eucalyptus for its growing up fast.

A community’s water supply is one of its most important infrastructures, as sufficient quality and quantity of water are as much prerequisites for human life as economic development. The rapid urbanization predicted for developing countries will cause serious water shortages in densely populated areas. The Lao People’s Democratic Republic (PDR) is taking precautions by planning and developing their water supply infrastructure to ensure reliable supply of water. We used the five capitals model of sustainable livelihoods to capture how a household makes a living and analyzed the effects of five forms of capital (natural, physical, human, financial, and social) on water consumption behaviors from the perspective of the residents’ livelihood. We conducted a survey to gain an understanding of the thought processes behind water consumption behavior in two villages in suburban Vientiane. The results indicated that natural and physical capital delayed connections to the water supply. Financial capital stimulated the purchase of high-quality water in preference to a connection to the water supply. This lack of connection is not necessarily sustainable in the near future, considering ongoing urbanization. Furthermore, this possibility presents a difficult problem, as residents do not usually acknowledge it. To accomplish sustainable development goals, this gap should be overcome.

The target date in 2015 for the United Nation’s Millennium Development Goals (MDGs) was reached, and a new period of global goals for the post-2015 is dawning. To assess whether and how regional progress towards achieving the MDGs has contributed to better quality of life in developing nations, we formulated a correlation between various aspects of human development, indicated by MDG indicators, and subjective well-being (SWB), a response to the question of how much people feel happy or satisfied. We demonstrated that national levels of SWB can be explained by the degree of development; poverty reduction is the strongest determinant, and achieving the MDGs is associated with higher SWB levels. Scenario assessment of SWB allowed which domain of development should be improved preferentially in each region to be determined, hence the SWB approach is expected to offer an innovative proxy of human development for the assessment of the Sustainable Development Goals (SDGs).
