Indoor oyster mushroom cultivation for livelihood diversification and increased resilience in Uganda

This practice describes indoor mushroom (Pleurotus spp.) cultivation as a means to diversify livelihoods and strengthen the resilience of farmers in Uganda. Indoor mushroom cultivation was promoted by the Global Climate Change Alliance (GCCA) project on Agriculture Adaptation to Climate Change in the central cattle corridor of Uganda. Mushrooms can be grown at very low cost and in relatively short time. It is a practice that can be adopted by small-scale farmers to diversify their income during the dry season, when lack of water may challenge the cultivation of other crops, and reduce their vulnerability to adverse weather. Indeed, mushroom production is done indoor and it requires little amount of water compared to other crops.

Multi-stress tolerant Green Super Rice in the Philippines. Cost benefit analysis based on field testing of some lines of Green Super Rice

How to buffer impacts of climate variability and dry spells in home gardens by using botanical pesticides and liquid compost, Cambodia

This technology offers a low-cost method used in Cambodia to control and manage pests for crop production while limiting adverse impacts of residue toxicity. It describes the methods of producing botanical insecticides and describes how to produce compost using the heap method and how to make liquid compost. The costs and benefits of the combined application of botanical insecticides with the production and use of liquid compost is presented.

Construction of traditional granary locally called "Colombier" in Haiti

Traditional agricultural adaptation practices in Haiti address the consequences of natural disasters, preventing and mitigating them. One such practice, intended to reduce the impact of droughts, floods and tropical cyclones and storms, is the construction of a granary called “Colombier”. It is a structure built on high posts where grains and beans may be stored for extended periods of time. This secures them from being washed away or otherwise damaged by catastrophic events. This technology explains how to use and construct a “Colombier”.

Fallow Cropping: Garlic after Rice, Philippines

The Philippines, due to its geographical location and physical environment, is among the world’s most disaster prone countries. The country regularly experiences floods, typhoons, monsoon storms and rains, and drought. The country is visited by an average of 20 typhoons yearly. These weather events have serve impacts on the agriculture sector, increasing the need for more resistant, sustainable and efficient production systems. Garlic cropping in the fallow period after rice was identified as a good practice option (GPO) as it can reduce the impacts of climate variability and risks associated with extreme weather events such as droughts, enhance livelihood security by augmenting household incomes, and promote crop diversification. Garlic is a cash crop with a quick return on investment. It requires minimal labor input so that on a small plot, a family household member can provide the labor. Fallow cropping of garlic after rice is thus considered as a GPO that can both increase the ecological (e.g. improved soil quality) and socio-economic (e.g. source of additional income) resilience of farming households, especially in disaster-prone countries like the Philippines.

Soil property and fertility improvement through composting using Trichoderma, Philippines

Composting improves the physical soil condition and can thereby reduce the risk and impacts of climate variability and extreme weather events such as droughts, dry spells and heavy rains. Healthy soil systems can better respond to temperature increases, changing rainfall patterns, increase evapotranspiration rates, alter pest and disease cycles, etc. Composting improves soil quality by promoting soil aggregation and preventing surface crusting, which enhances water infiltration, plant root penetration and soil aeration. This also prevents surface run-off and erosion. It also conserves the nutrients contained in animal manure, sewage sludge, and similar materials. Further, it supplies the plant growth hormones not found in inorganic fertilizers. Composting likewise increases the buffering capacity of soils and minimizes the adverse effects of soil acidity and alkalinity. These result in reduced farm input costs because less chemical fertilizer is needed. The application of Trichoderma accelerates composting of organic materials available in vegetable farms. For disaster prone countries like the Philippines, soil property and fertility improvement through rapid composting is therefore seen as a good practice option to enhance overall resilience and prevent high production losses due to degraded or eroded soils.

Improved domestic stoves to enhance energy efficiency and reduce consumption of wood & organic matter, Bangladesh

In Bangladesh every year more than 39 million tons of traditional fuel e.g. wood, straw, leaves, dried cow dung etc. are used for cooking and other purposes, and the figures are rising due to population growth. The traditional stoves used in rural Bangladesh however are very inefficient devices. Experiments have shown that these stoves only use 5-15 % of the total heat energy, while the rest goes wasted. Furthermore, they emit poisonous gases, creating health hazards to users, especially children and elders, and polluting the environment. To stop inefficient use of valuable fuels and to create healthy and pollution-free environment, the Institute of Fuel Research and Development (IFRD) of the Bangladesh Council for Science and Industrial Research (BCSIR) has developed improved stoves suitable for household level use. These types of stoves can save 50-70 percent fuels compared to traditional ones, thereby increasing their energy efficiency. The broader use of improved stoves is a critical contribution to also save on wood and organic matter otherwise used for cooking.

Alternative seedbed methods for t. aman rice under drought prone conditions, NW-Bangladesh

The agriculture sector in Bangladesh is highly sensitive to climate variability and climate change. Agriculture-based subsistence economy employs almost two thirds of the population, and adaptation to climate change is vital to maintain sustainable development. In Northwestern Bangladesh adaptation practices need to target transplanted aman rice, the most important crop in the Barind Tract under rain fed situations. In order to improve its resilience to increased drought frequencies and to inadequate availability of water for irrigation at critical cropping stages, alternative seedbed methods have been developed.

Farm yard manure and water hyacinth compost applications to enhance organic matter and water holding capacity of soils in drought prone areas of Bangladesh

The impacts of climate variability and change are critical in Bangladesh. The northwest of Bangladesh is recurrently exposed to high risks of drought and drought spells. The vulnerability of the sector is high, and is further increasing due to constantly increasing water requirements, growing cropping intensity and high population pressure. One strategy to strengthen the resilience of farming systems to drought is to enhance the organic matter levels in soils for better soil moisture retention and water infiltration. The preservation and increased application of farm yard manure, which is organic matter prepared from various kinds of locally available animal excreta mixed with other organic materials is a suitable technology to augment the organic matter content in soils. It also enhances the water holding capacity and fertility of soils whose productivity has been negatively affected by recurrent exposure to droughts.

Risk diversification through taro (Colocasia esculenta) cultivation in areas prone to floods and water logging, Bangladesh

Bangladesh is highly vulnerable to water related disasters particularly during the monsoon season. Most climate models predict that precipitation levels will increase significantly during summer monsoon. During exceptionally severe seasonal floods water can stay on the ground for more than a month, destroying and damaging tens of thousands of hectares of cultivated land, and ultimately resulting in food shortages that may threaten lives of millions of people. Many of the poor people who live in rural areas and depend on agriculture are highly exposed to severe flooding. Growing crops with high potentials to withstand flood impacts and survive in water logged conditions, such as the aroid Mukhi kachu (taro), is a crucial risk diversification strategy. The Bangladesh Agricultural University (BAU) has developed three suitable cultivars, namely 'Latiraj' (pani kachu), 'Bilashi' and 'Dowlatpuri', in collaboration with Bangladesh Agricultural Research Institute (BARI).
