In the last two decades, many development projects have been undertaken by different GOs and NGOs in diverse areas of the world with the expectation that they will simultaneously address the challenges of declining rural livelihoods and biodiversity. Caritas Bangladesh, a leading national and non-profit organization, has implemented several social welfare and community development projects since the 1970s. Accordingly, Caritas implemented a noble project in 2019, namely: Improving the livelihoods of extremely poor people by promoting green energy and biodiversity in the aspect of climate change in disaster-affected areas of Bangladesh (ILPGB). Therefore, the objective of the study was to evaluate the impacts of the ILPGB project on the livelihood and biodiversity improvements of the rural farmers in the Netrokona and Sunamgonj districts of Bangladesh. The assessment was done through random samplings of 60 stakeholders using a semi-structured questionnaire for livelihood analysis and quadrat (10 x 10 m2) plotting techniques in the farmer's homestead for biodiversity analysis. The results showed that the ILPGB project had brought changes, most of which have had positive impacts on the human, social, physical, economic, and natural capital of the participants, and the process of livelihood development was slow but showed improving trends. Nevertheless, a platform for social relations and networks has been created among the participants in the project implementation areas. On the contrary, a total of 34 plant species were identified in the participants' homestead, of which 18 were trees, 6 shrubs, and 10 herb species. The species dominance showed that farmers tend to grow fruit tree species for their family's needs, and the general plant diversity in the northeastern region of Bangladesh was moderate to low. So, the study strongly recommends that the ILPGB project should continue for another two to three years. During this time, farmers could easily build their livelihood capital and improve their homestead biodiversity with the help of the project's planting materials and agricultural inputs.
Poor soil quality and decreasing crop yields brought on by ongoing monocropping in the fields of small-scale farmers in Bangladesh have demanded a search for sustainable production methods that are more resource efficient and environmentally friendly. Conservation agriculture is such a beneficial approach that effectively addresses crop productivity and soil quality enhancements using locally available resources. Therefore, the objective of the study was to determine the impacts of conservation agricultural practices on the growth and yield of summer vegetables cultivated in the northern region of Bangladesh. The study was carried out at farmers field situated in the Chilmari upazila of Kurigram district using the Randomized Complete Block Design (RCBD) with three replications during July to September 2020. The trial vegetables, i.e., Red amaranth, Kangkong and Indian spinach had showed the better yield of 4.95 t/ha, 14.5 t/ha and 19.5 t/ha in compared with traditionally cultivated vegetable cultivated methods in the farmers field, according the conservation agriculture method had enhanced vegetable yield. As part of conservation agriculture practices, soil organic matter content, total nitrogen, phosphorus, and potassium levels, as well as pH for better crop production, were all positively increase with the implications of conservation techniques like, adding organic manure, minimal tillage, permanent crop residues and crop rotation. Therefore, the study came to the conclusion that traditional agriculture would need to adopt conservation agriculture methods in order to produce more food while using fewer resources and doing so in a more efficient manner while having the least possible negative effects on the environment.
