“…Cattle also form a large part of livestock production by farmers. The livestock density in Bangladesh is about 376 heads/km 2 (Das et al 2020). Das et al (2020) also estimate the total number of cattle, sheep and lamb to be 24.16 million, 26.18 million and 3.5 million, respectively.…”

Delta's, waar land en water samenkomen, zijn altijd al aantrekkelijke plaatsen geweest om te leven. Ze bieden goede omstandigheden voor landbouw met gemakkelijk toegankelijke transportmogelijkheden over water. Dit is ook zo in de Bangladesh delta: de delta is een belangrijke bron voor voedsel in de regio.Echter, vanwege toegenomen ontwikkelings-en klimaat gerelateerde risico's zoals overstromingen, cyclonen, droogte-en hittestress en zoutintrusie zijn delta's ook in toenemende mate kwetsbare gebieden. Levens van mensen en vee en de productiviteit van de landbouw en aquacultuur worden hierdoor bedreigd. Door veranderingen in zeespiegelstijging, temperatuur en neerslag, verzilting, waterkwaliteitsproblemen, droogte en overstroming, bevolkingsdruk en verstedelijking, staat de landbouwproductie onder druk. Andere factoren die voedselzekerheid bedreigen zijn onder-en overgewicht, en ook voedselveiligheid is een bron van zorg vanwege beperkte handhaving van regelgeving terwijl er wel chemicaliën in de landbouw worden gebruikt. In het zuidwesten van Bangladesh is verzilting van zowel bodem als water een bijzonder aandachtspunt, wat de voedselproductie van de regio ernstig bedreigd.De vraag is hoe hier mee om te gaan, nu en in de toekomst. Er zijn, naast voldoende voedsel produceren, nog drie doelen: 1. inkomensmogelijkheden voor boeren veilig stellen, 2. gezond voedsel produceren, terwijl vanwege een toenemende stedelijke bevolking de verwachting is dat de vraag naar eiwitten zal toenemen terwijl het landbouwareaal zal afnemen; en 3. tegelijkertijd milieuvervuiling en klimaatverandering het hoofd bieden. In het onderzoek wordt hiervoor een voedselsysteemanalyse gedaan, die in dit rapport wordt beschreven, met nadruk op de zuidwestelijke delta van Bangladesh. Een start wordt gemaakt met de beschrijving van mogelijke veranderpaden richting de toekomst. Er wordt gekeken naar 1. De combinatie mangrove en garnalen; 2. Verbeterd land-en waterbeheer; 3. Aanpassing van veeteelt aan klimaatverandering, inclusief verzilting; en 4. Veranderend gedrag bij boeren. Het onderzoek over veranderpaden staat nog in de kinderschoenen, en vervolgonderzoek met betrokkenen biedt daarom veel perspectief.Deltas, as areas with both land and water, have always been attractive places to live because they offer good conditions for agriculture, and because navigation was for a long time important for transport. These reasons apply also to the Bangladesh delta, the most important food system for the region. However, the food production system is experiencing (increasing) pressures that threaten food security. The Bangladesh delta has become more vulnerable to development and risks related to climate change, including floods, cyclones, drought, heat stress and salinity intrusion, threatening humans and livestock and reducing agricultural and aquacultural potential. Due to changes in the area of sea level rise, temperature and precipitation changes, salinisation, water quality problems, drying out and flooding, population pressure and urbanisation, agr...

“…However, Bangladesh consumes about 105,14 tons of CH4 and 84.25 tons of carbon dioxide (CO2) annually, resulting in 1.16 tons/ person/year greenhouse gas emissions (Knoema, 2021). The CH4 in Bangladesh is mainly emitted from various sources, including paddy fields, livestock, landfills, leaky natural gas pipelines, and coal stockpiles (Begum et al, 2018;Das et al, 2020;Clark et al, 2021).…”

This paper investigates the probable nexus between methane (CH4) and air pollutants, a public health hazard in Bangladesh. The hypothesis considers that the concentration of CH4 is dependent on the ten air pollutants found in the five districts in Dhaka Division, a major urban and industrial area in Bangladesh. These pollutants are: Particular matters (PM2.5), Nitrogen dioxide (NO2), Nitrogen oxide (NOx), Aerosol optical thickness (AOT), Sulfur dioxide (SO2), Carbon monoxide (CO), Ozone (O3), Black carbon (BC), Formaldehyde (HCHO) and Dust. The study applies Machine Learning (ML) technique and Geographically Weighted Regression (GWR) Modeling. Temporal CH4 datasets from the Sentinel-5P sensor are classified to estimate the annual CH4 concentration during 2019-2021.Seven supervised classifiers of ML coupled with the GWR model are used to predict the statistical and spatial relationships. CH4 increases gradually during 2018-2021 in Dhaka, Gazipur, and Munshiganj Districts. It relates differently with various air pollutants, e.g., positively with BC, Dust, NO2, PM2.5, O3, and AOT, and negatively with NOx, CO, HCHO, and SO2.This study results that Rational quadratic (RMSE-0.001, MAE-0.001, R2-0.96), Random Forest (RMSE-0.004, MAE-0.003, R2-0.91), and Stepwise regression (RMSE-0.002, MAE-0.002, R2-0.87) are the suitable method in ML. The highest goodness-of-fit (R2) of 82%-96% is found in Dhaka and Narshingdi Districts. The key findings may help formulate the appropriate action plan to mitigate ongoing and future air pollution in Bangladesh. In addition, the methodology of the research may be applicable elsewhere nationally and internationally for air pollution research.

“…The GHG from the livestock sector has been calculated through research on a regional scale such as research by Li et al (2016), Mottet et al (2017), Nugrahaeningtyas et al (2018), Zuratih and Widiawati (2019), Das et al (2020), Ammar et al (2020), Arifin et al (2021), andSarah et al (2021). This research also measures GHG in the livestock sector because this is urgent, but the research capacity is still limited in developing countries (Munidasa et al, 2021).…”

The livestock sector is one of the most significant contributors to greenhouse gas (GHG) emissions. Jetak Village in Indonesia has a large livestock population, so it has the potential to be a reasonably high contributor to GHG emissions. Therefore, research is needed to calculate GHG from the livestock sector and calculate biogas potential. Besides, we also discuss data collection techniques that are important but often forgotten in GHG reduction studies in developing countries. This is useful as an effort and reference to reduce GHG emissions in rural areas, especially in Jetak Village. The GHG calculation uses the Tier-1 method, while the data on the potential for biogas utilization is obtained from manure production calculations and in-depth interviews. The calculation results show that the highest total GHG from livestock management in Jetak Village in 2017 was 1,106.69 tons CO2-eq/year, while the lowest total GHG emissions in 2015 were 1,018.41 CO2-eq Gg/year. Dairy cows are the biggest emitter in livestock management, with 4,919.61 tons of CO2-eq/year, and laying hens are the lowest emitters with 1.39 tons CO2-eq/year. Dairy cows are the largest contributor to GHG emissions in enteric fermentation with 9,680.52 tons CO2-eq/year, and the lowest number of contributors is horses with 20.79 tons CO2-eq/year. The potential of biogas in Jetak Village based on manure production is 137 installations. The positive community's perception supports this. It tends to be less valid regarding livestock population data used for GHG calculations, so we verified it during in-depth interviews. The in-depth interview process used local language to enhance the quality of responses. This research needs to be developed considering our findings that there are only 50 biogas installations, indicating the biogas potential is not being utilized to its full potential.
