PREFACEIt is very gratefully to hold the International Conference on Agro-Environmental
Science under the collaboration between the International Society of Environmental and
Rural Development, ISERD, and the Graduate School of Agro-Environmental Science,
Tokyo University of Agriculture, Japan.
ISERD holds the official conference annually, which is the International Conference
on Environmental and Rural Development, shortly ICERD, around in March every year.
The hosts as well as venues are rotating among the collaborative organizations, so far 6
times were held in Cambodia, 5 times in Thailand including coming the 15th ICERD in
March 2024, 2 times in Philippines, and once in Myanmar and Tokyo, respectively. Even
during the Covid Pandemic in 2020 and 2021, ISERD held the 12th ICERD online hosted
by the Bohol Islands State University in Philippines in 2020, and the 13th ICERD onlineby the Research Center, Institute of Environmental Rehabilitation and Conservation inTokyo in 2021. We have been prioritizing to have an academic interactions/communication through holding ICERD for discussing the effective connection between
research outcomes and agricultural and rural development in each site, in addition to thedirections of the society for deepening further collaboration among the collaborative
organizations.
Separately from the official conference, ICERD, it is the first time for ISERD to holdthe International Conference on Agro-Environmental Science with the Graduate Schoolof Agro-Environmental Science, Tokyo University of Agriculture, Japan. Tokyo
University of Agriculture, shortly Tokyo NODAI founded in 1989, is one of the long
historic and strong universities in Japan. Tokyo NODAI has wide and deep educationaland research fields in agriculture and related fields with 23 departments in 6 faculties/
graduate schools.
With the collaboration of the Graduate School of Agro-Environmental Science,
Tokyo University of Agriculture, we do believe this event would offer more international
academic experiences to the graduate school students and scientists.

Abstract
Farmer-led agricultural innovations are increasingly viewed as a potential approach tosustainable agriculture especially promoting rural revitalization, soil fertility
improvement and mitigating agricultural non-point source pollution. The complex natureand formidable challenges that characterize social-ecological systems especially indeveloping countries and rural landscapes, demands a transformation towards sustainable
futures. Improving the well-being of vulnerable people in rural areas while
simultaneously promoting sustainable resource management and building resilience toshocks, are global challenges that require identification of sustainable pathways, effective
processes and trajectories with the potential to facilitate the transformation of the socialecological systems. Autonomous agricultural innovations that are immerging in rural
areas can help in achieving sustainable agriculture and enhance ecosystem services byimproving multiple indicators of human well-being while creating synergies among
various ecosystem components and enhancing their supporting services. Despite thepotential role of autonomous agricultural innovations, very few cases have documented
on their impact on various natural resources, and wider environmental ramifications.
Using data from Lake Malawi National Park’s enclaved villages of Chembe in Mangochi
District, Southern Malawi, we investigated the role of an autonomous innovation inagriculture, a community garden and evaluated its impacts on one of the key natural
resources, soil and consequential implications of the innovation on wider ecosystemcomponents. We analyzed soils for micronutrients to obtain baseline data and provide abenchmark study for long term monitoring and management. A selected panel ofmicronutrients in soils were measured using Atomic Absorption Spectrometry (AAS)
after acid block digestion with a mixture of concentrated nitric acid (70% HNO3) andHydrogen peroxide (30% H2O2). Measured micronutrients included zinc (Zn), manganese(Mn), copper (Cu), iron (Fe) and selenium (Se) from soil samples obtained from theautonomous innovation and contrasted with other ecosystem types within the study area
namely; continuous maize farm, dambo wetland, bare land and forest land. Our findings
indicated that mean soil Zn and Mn concentration from the autonomous innovation weresignificantly high (1.51, 663 mg/kg respectively) compared to the rest of the ecosystem
types (p<0.0001). Soils of the community garden also showed remarkable improvementsin pH (5.6) compared to the maize farm and bare land (4.6, 4.8 respectively). Apart from
improving the quality of life of the community through routine distribution of vegetables
to vulnerable households, thereby offsetting the burden to overharvest resources from theforest or lake ecosystems, there were apparent benefits of the innovation on wider
ecosystem components. While different forms of agricultural innovation have radicallydifferent outcomes in diverse landscapes, our findings on the autonomous innovation in
Chembe indicate positive outcomes and underscore the relevance of similar innovations
as potential pathways for sustainable and positive farmer-led agro-environmental
initiatives.

Abstract
Severe climate changes in arid and semi-arid regions, for example rising summer
temperatures, lowering winter temperatures, and a lack of rainfall, have made calcareous
soils' fertility concerns, more specifically nitrogen and phosphorus deficits, progressively
worse. This study investigated the effects of sole and combined application of SM and
DAP fertilizer namely FT1 (SM = 0%, DAP= 0%), FT2 (SM= 100%, DAP= 0%), FT3(SM = 0%, DAP= 100%), FT4 (SM = 50%, DAP= 75%), FT5 (SM = 50%, DAP= 50%),
and FT6 (SM = 50%, DAP= 0%) on growth, photosynthesis, and yield parameters ofsoybean cultivar (LD 04-13265 USD) in calcareous soil of a semiarid region in Parwan,
Afghanistan. The results indicated that plant height and nodule number were unaffectedby fertilization treatments, however growth features including leaf number, root length,
and shoot biomass affected significantly. The photosynthesis parameters except
intercellular CO2 concentration were found to be significantly higher in FT4 and FT5,
compared to FT1 (control). As a result, combined application of SM and DAP
fertilizations such as FT4 and FT5 revealed better growth performance, higher
photosynthesis efficiency as well as producing more seed yield compared to solefertilizations. Ongoing studies can investigate the long-term effects of combining SM and
DAP fertilizer on soil health parameters in calcareous soils. This can include assessingchanges in soil pH, organic matter content, microbial activity, and nutrient cycling
processes. Understanding these dynamics will contribute to sustainable agricultural
practices and long-term soil fertility improvement.

Abstract
Urban green spaces (UGS) remain significant refuge for biodiversity conservation inhighly urbanized areas. However, the invariable anthropogenic interference in the UGSs
driven by economic incentives and partial interdisciplinary implications have led toincreased soil sealing. We examined the extent of soil sealing, natural soil area, tree
canopy cover, and tree species number of 26 UGSs in Tokyo Metropolitan Area, Japan,
and established the are-species relationships. The number of tree species across the UGSs
were intermediate and strikingly similar across the UGSs, ranging from 143 – 19.
Compared to other UGS types, The proportion of sealed surfaces was significantly
different across the different UGS types (<.000), ranging from 58.82% - 0%. Japanesestyle gardens and conservation areas exemplified low proportion of sealed surface.
Correlations between natural soil area, tree canopy cover, and tree species richness werehighly significant at p<0.01; natural soil area and tree species (rho = 0.754 **, n=26),
tree canopy cover and tree species richness (rho = 0.766 **, n=26,), natural soil area andtree canopy cover (rho = 0.986 **, n=26). These findings have significant implication on
urban planning policy and biodiversity conservation.

benefits. However, media and light conditions affect microgreens' growth and nutritional
content, which may limit their production in rural community settings. Brassica carinata
is an essential local Kenyan vegetable, but its production and full utilization are limited
by its early maturity. The potential of using B. carinata as a microgreen would be an
excellent alternative production technique to circumvent its early maturity limitation.
This study investigated the influence of white and blue light on Vitamin C and phenols
content in B. carinata microgreens. Microgreens were grown for 14 days in a growthchamber using plastic punnet containers filled with cocopeat and sand under white andblue light. The capillary wick watering technique was used for irrigation. Temperatureand relative humidity were monitored and maintained at 25ºC and 60%, respectively. The
photoperiod and intensity of light were also maintained at 12 hr and 160 ± 2.5 µmol
m−2s−1) respectively. After 14 days, microgreens were harvested and freeze-dried toanalyse phenols and Vitamin C. Data was subjected to ANOVA and means separated by
Tukey’s multiple comparison test. Results indicated that light had no significant effect on
B. carinata phenol content. However, microgreens grown in sand showed statisticallyhigher amounts of phenol content than those grown using cocopeat. For vitamin C content,
media and light showed no significant effect. Based on our results, sand, as a locallyavailable medium and in either light, can equally be used to produce microgreens forphenols and Vitamin C for Brassica carinata.

Corresponding email:12423401@nodai.ac.jp
Abstract
Urban areas present a challenge of imbalance in the diversity of the planted species oftrees and other planted herbaceous plants. The limited planting space therefore depicts
urban areas as locations of low biodiversity. This research focused to compare thediversity of trees and herbaceous plants growing in selected green children’s parks andstreet lanes of Setagaya ward. This research also highlighted the regeneration mechanism
and relevance of herbaceous plants species surveyed in the selected survey sites of
Setagaya. Six urban street lanes stretching a distance of 18.3 km, and 18 green children
public parks covering an area of 21,045.5 m2 were surveyed. A total of 49 tree species
belonging to 28 families were surveyed. Of these, 15 species are exotic while 34 species
are native to Japan. A total of 26 tree species and 38 tree species were surveyed on street
lanes and in public parks respectively, 15 tree species were surveyed in both land uses.
Also, a total of 46 herbaceous plant species were surveyed. A total of 33 herb species and
29 herb species were surveyed on street lanes and in public parks respectively. 16
herbaceous plant species were surveyed in both land uses. Six herb species are dispersedby birds, one species by explosion mechanism, seven species by humans, 12 species bywater and 14 species by wind. 60 % of herbaceous species have medicinal value, 40%
have food value, 57.5% have ornamental value, 7.5% have materials value. The parks
surveyed have higher Shannon-Weiner species diversity index of 3.1452 and that of street
lanes is 2.5312. Street tree species include Liquidambar formosana, Liriodendron
tulipifera, Ginkgo biloba and so forth. Park tree species include Osmanthus fragrans,
Zelkova serrata, Quercus myrsinfolia and so forth.

Abstract
Rapid growth in the global population leads to increased consumption and generation ofwaste that ends up in dumpsites and landfills, which are the most common ways todispose of waste throughout the world. Municipal solid waste's life-cycle activities andbreakdown contribute significantly to greenhouse gas emissions (GHGs). Composting isan environmentally friendly method of managing organic waste, but it has a substantial
downside in the form of greenhouse gas emissions; including carbon monoxide (CO),nitrous oxide (N2O), methane (CH4), and carbon dioxide (CO2). The aim of this study
was to access the dynamics of (GHGs) i.e., CO2 and CH4 emission, the physical andchemical characteristics of food waste during composting. Five treatments comprised of;T0 = 100% cow dung (CD); T1= 75% CD + 25% FW; T3= 50% CD+ 50% FW and
T4=100% food waste (FW)+0% CD were set up. GHG emission and physical properties
not limited to; soil moisture, soil organic matter (SOM) and soil organic carbon (SOC)
were sampled and measured weekly. Chemical properties analyzed included total
nitrogen (TN), total Phosphorus (TP) using a spectrophotometer, pH, electricalconductivity, K+, Na+ and Ca2+. The results indicated that there was no correlation
between GHGs emission, physical and chemical properties of the compost. However,there was a strong correlation at between TN, SOM, and SOC p<0.01 during the fifth
week of the composting.

Abstract
Developing countries suffer severe socio-economic consequences from extreme weather
events, including livelihood losses and increased costs. Identifying climatic andhydrologic events through trend analysis is essential for managing water resources. The
study focuses on the Diamphwe River basin in central Malawi, a crucial area supporting
wetland (dambo) ecosystems, agriculture (rainfed and vegetable-irrigated wintercropping), and water supplies for the Dedza and Lilongwe districts. Using statisticalanalysis methods such as Mann-Kendall, Pettit, and Standardized Precipitation Index(SPI), the study examined hydrologic trends from 1975 to 2010 to identify long-termhydrologic trends in the region that are important for improving agricultural productivity.
The research findings revealed a high correlation between rainfall and increased land user
time. However, rainfall significantly impacts river discharge only during the rainy season.
In the dry season, water for river discharge comes from sources like aquifers andsubsurface flow. Through the Pettit test and SPI, it was discovered that 1989 was atransition year, and the 1991-2000 decade was the dryer decade with the worst drought
during the 36-year project period. The study concludes that decreasing trends in rainfall
and river discharge, along with a sudden drop in 1989 and drought, indicate a changing
climate in the river basin. This change is linked to increased land use, reducing forest land.
The research offers essential insights to water and environmental stakeholders, helping
them develop region-specific policies based on research to mitigate and adapt to thepotential negative impacts of climate change on society and the environment. The
research is also valuable for farmers and local authorities, as it provides helpful
information on tackling climate change challenges in agriculture in order to improve theefficiency of the proposed multi-purpose dam project on the river.

Abstract
Adoption of improved crop cultivation technologies has been to be slow in Sub-SaharanAfrica (SSA), leading to lower yields and starvation. This study examined the adaptationof two vegetables indigenized in Malawi, Amaranthus retroflexus (Vegetable Amaranth)and two cultivars of Phaseolus vulgaris (common bean), to hydroponic cultivation. Yield
and growth were compared using a Nutrient Film Technique (NFT) hydroponic system
in Yokohama, Japan. Amaranthus showed excessive growth with a marked apicaldominance. Both bean cultivars were successfully grown under hydroponics with nosignificant differences. The hybrid cultivar however had significantly lower specific leaf
area (SLA), suggesting a genetic predisposition. These two vegetables can be further
tested in hydroponics. For amaranth, it needs to be investigated if de-budding can
suppress apical dominance and promote above-ground biomass.

Abstract
The effluents from wastewater contain nutrients that have been identified as the primarycauses of eutrophication in natural waters. A case study from Cheung Ek, an urban
wastewater lake in Cambodia, has indicated polluted with NH4+ (18-22 mg/L) and PO43(2.3-4.6 mg/L). Even though phytoremediation through water morning glory cultivation
was introduced into the lake, only a certain amount of nutrients can be removed from thelake’s water (65.22% and 17.36% for NO3- and PO43-, respectively). Hence, thiswastewater’s lake must receive suitable treatment before being discharged into otherwater bodies. Low-cost and high-performance materials or techniques that could
synergistically remove pollutants in a simple manner are highly desired. Therefore, themain goal of this research study is to evaluate the CSH synthesized from calcium
hydroxide Ca (OH)2 and rice husk ash as a promising strategy both economically andenvironmentally friendly for wastewater treatment as well as nitrogen and phosphorus
recovery. The CSH material was prepared by combining calcium hydroxide Ca (OH)2and rice husk ash with a ratio (1:4) and mixing with 75% deionized water. Following theprocess with a vibrator from 1 to 3 minutes, the CSH was kept in the mold for 3 weeks atroom temperature before starting the experiment. The absorption experiment considers
parameters such as pH, EC, Ca, K, NH4+, and PO43- in 2 weeks period. Results of theabsorption experiment indicated that CSH can effectively remove nutrients fromwastewater, achieving removal rates of 97% for PO43-and 98% for NH4+. The absorption
capacity of CSH is 0.11 mg-PO43-/ g-CSH and 0.065 mg-NH4+/g-CSH. These results
suggest that CSH, derived from Ca (OH)2 and rice husk ash, could serve as a costeffective solution to water pollution in Cambodia, given the material's affordability andwidespread availability throughout the country.

International Society ofEnvironmental and Rural Development
Philosophy of ISERD:
Recently, in developing countries, subsistence agriculture is being converted to export-oriented monoculture, and the amounts of agricultural chemicals applied to the farmland are increasing every year. The
applied chemicals in farmland cause serious environmental problems downstream such as eutrophication,
unusual growth of aquatic plants, decrease in dissolved oxygen and accumulation of bottom mud in water
resources. Also, there seem to be many cases in which people apply agricultural chemicals without
understanding its impact to health and food safety. Therefore, it is necessary to promote and enhance
understanding of sustainable rural development among local stakeholders including farmers.
Sustainable rural development aims to meet human needs while preserving the natural environment.
As it should cover not only social and economic development but also natural environment conservation,
no single organization can achieve sufficiently the aspirations of sustainable rural development.
Collaboration among international, governmental and non-governmental organizations, together with theacademe and scientific sector, is indispensable.
The knowledge and intelligence accumulated in universities and research institutions are also expected
to make the programs facilitated by the international, governmental and non-governmental organizations
more adequately implemented and meaningful to societal development. However, these cases especiallythose implemented locally have been scattered without having been summarized well or recorded in annals
academic or scientific societies.
So, the International Society of Environmental and Rural Development founded in 2010, aims todiscuss and develop suitable and effective processes or strategies on sustainable rural development focusing
on agricultural and environmental aspects in developing countries. The ultimate goals of the society are tocontribute to sustainable rural development through social and economic development in harmony with thenatural environment, and to support the potential or capacity building of local institutions and stakeholders
in the rural area with academic background.

Purposes of ISERD:
The primary purposes of ISERD are to contribute to sustainable rural development through social andeconomic development in harmony with the natural environment and to support the potential or capacity
building of local institutions and stakeholders in the rural area with academic background.
In order to enhance the realization of the primary purposes of ISERD, the secondary purposes are;- to facilitate interaction among international, governmental, non-governmental organizations and local
communities,- to hold conferences or symposia on environmental and rural development,- to edit the International Journal of Environmental and Rural Development,- to confer some awards based on scientific achievement, research paper or poster presentation, and- to encourage and develop local awareness concerning sustainable rural development.
