Weather Events

Being a country in the Himalayas, Bhutan is highly prone to the vagaries of weather events that affect agricultural production and the subsequent livelihood of the people. To identify the main issues that affect crop production and the decisions of farmers, a survey was conducted in three different agro-ecosystems in Bhutan. Our key findings indicate that farming and the decisions of farmers were largely affected by different climatic and non-climatic factors. These were in descending order of importance: irrigation availability > farm labour > crop seasonality > crop damage (climatic) > land holding > crop damage (wildlife) > crop damage (diseases and pests). The most important consequences of climate change impacts were the drying of irrigation sources (4.35) and crop losses due to weather events (4.10), whereas land fallowing, the occurrence of flood and soil erosion, weed pressure and changes in cropping pattern (with mean ratings of 2.53–3.03) experienced lesser consequences. The extreme weather events, such as untimely rains, drought and windstorms, were rated as the ‘most common’ to ‘common’ occurrences, thus inflicting a crop loss of 1–19%. These confirm our hearsay knowledge that extreme weather events have major consequences on irrigation water, which is said to be either drying or getting smaller in comparison to the past. Therefore, Bhutan must step up its on-ground farmer-support system towards improving the country’s food production, whilst embracing climate smart farm technologies for adapting to the impacts of change.

The study was conducted to know the productivity and soil fertility status of intensified rice-wheat (RW) systems by adding a third pre-rice crop mungbeani.ewheat-mungbeanrice cropping pattern. The trial comprises five packages of practices including crop residue retention, seeding methods with tillage options imposed on the component crops in the same cropping pattern. The results indicated that keeping standing 30% crop residue in the field with minimum disturbance of soil had significant contribution on grain yield of wheat-mungbean-rice sequence compare to conventional practice of well-till without crop residue retention. System productivity and fertility were evaluated under five levels of tillage options (zero, strip, raised bed, minimum tillage by power tiller operated system (PTOS) and conventional tillage practice (CTP) in a RWM cropping pattern. Both permanent raised bed and strip till with 30% straw retention produced the highest productivity in all years and the lowest yield was also found from conventional practice with 30% straw retention.Soil organic matter in surface soil had increased by 0.12% after 3years crop cycles with 30% SR from rice and wheat and full residue retention from mungbean crop. Straw retention is an important component of soil management and may have long term positive impacts on soil quality. The combination of raised bedsystems and strip tillage with 30% residues retained appears to be a very promising technology for sustainable intensification of wheat-mungbean-rice croppingpattern in dry zone areas.

Role Of Information

Farmers in the lower Bengal Delta around the city of Khulna, Bangladesh, are particularly vulnerable to hydro-climatic variability. Phenomena such as heavy rain, drought and salt intrusion increasingly affect their crop production, with far-reaching socio-economic and environmental impacts. Reliable hydro-climatic information service received in a timely manner could help farmers improve their responses to hydro-climatic variability, thus improving their agricultural decision-making. However, significant challenges persist regarding information uptake and the role of information from the available sources. We designed an explorative research framework combining different participatory methods and analysis of climate data. Our aim was to examine three key research questions: (i) what information is currently available to farmers for agricultural practices and decision-making? (ii) what is the perceived quality of the available hydro-climatic information in response to water and weather related stresses? (iii) how does the available information influence farmers’ decision-making? We found that farmers had access to information from five main sources: informal contacts, formal contacts, education and training programs, traditional media (like television) and modern ICT tools/social media. However, informal contacts, particularly with peer farmers and private input suppliers, were the farmers’ main source, in addition to their own previous experiences. Farmers perceived hydro-climatic variability as high and the quality of available hydro-climatic information as poor. They indicated a need for more accurate, time-specific, trusted and actionable information for improving agricultural decision-making. We conclude that there is high potential and need for hydro-climatic information services tailored for farmers in the study area.

The Impact

A computer simulation model to analyse risks of soil erosion to long-term crop production is described. The model, called PERFECT, simulates interactions between soil type, climate, fallow management strategy and crop sequence. It contains six main modules; data input, water balance, crop growth, crop residue, erosion and model output. Modules are arranged in a framework that allows alternative modules to be used as required for the potential range of applications. The model contains dynamic crop growth models for wheat, sorghum and sunflower. Validation of PERFECT against small catchment and contour bay data collected throughout Queensland showed that PERFECT explained up to 84% of the variation in total available soil water, 89% of the variation in daily runoff, and up to 75% of the variation in grain yield. Average annual soil erosion was accurately predicted but daily erosion totals were less accurate due to the exclusion of rainfall intensity in erosion prediction. Variability in climate dominates agricultural production in the subtropical region of Australia. The validated model can be coupled with long-term climate and soils databases to simulate probabilities of production and erosion risks due to climatic variability. It provides a method to determine the impact of soil erosion on long-term productivity.

The Impact

SUMMARYWater scarcity is a major constraint of agricultural production in arid and semi-arid areas. In the face of future water scarcity, one possible way the agricultural sector could be adapted is to change cropping patterns and make adjustments for available water resources for irrigation. The present paper analyses the temporal evolution of cropping pattern from 1960 to 2008 in the Hetao Irrigation District (HID), China. The impact of changing cropping patterns on regional agricultural water productivity is evaluated from the water footprint (WF) perspective. Results show that the area under cash crops (e.g. sunflower and melon) has risen phenomenally over the study period because of increased economic returns pursued by farmers. Most of these cash crops have a smaller WF (high water productivity) than grain crops in HID. With the increase of area sown to cash crops, water productivity in HID increased substantially. Changing the cropping pattern has significant effects on regional crop water productivity: in this way, HID has increased the total crop production without increasing significantly the regional water consumption. The results of this case study indicate that regional agricultural water can be used effectively by properly planning crop areas and patterns under irrigation water limitations. However, there is a need to foster a cropping pattern that is multifunctional and sustainable, which can guarantee food security, enhance natural resource use and provide stable and high returns to farmers.

To plan cropping pattern and to bring out agricultural potential of a region, it is essential that the agro climatic classification is made on an objective and rational basis. Such an attempt has been made in this paper by devising an index called Water Availability Index (WAI). This index takes into account the distribution of the minimum water required by the crop. It utilizes the most probable number of the wet weeks for three threshold values of weekly rainfall and probability of dry spells of more than three weeks. The methodology developed is applied to dry farming tracts of Karnataka State. Using these information along with the information of the soil types and water requirement of different crops, cropping pattern can be assessed in each agro climatic zone, so that optimum use of the available moisture is made in stabilizing the crop production in the State.

The World

The effects of climate change on agriculture are being witnessed all over the world. Rainfed agriculture is likely to be impacted severely in view of its’ high dependency on monsoon, the likelihood of increased extreme weather events due to aberrant behavior of south west monsoon. Anantapur, Akola, Solapur and Bijapur districts in India were selected for the study because, rainfed area is more than irrigated area and rainfall is the most critical factor affecting crop production in these districts. Major perceptions of climate change in the four rainfed study districts were prolonged dry spells, rise in temperatures, and delayed and shorter rains. Major adaptation measures towards climate change in four study districts were insurance, change in planting dates and cropping pattern. Majority of farmers positively agreed with attitude towards climate change statements which augurs well for current and future adaptation actions. As farm-level adaptation becomes an increasingly important across the world, policies at all levels will need to be accounted for appropriate factors, including perceptions and how perceptions affect human behavior and adaptive actions. Adaptation through transformation (in the present study diversify to livestock and work as labor) has the potential to become an inclusive, engaging and empowering process that contributes to alternative and sustainable development pathways which needs to be encouraged. The present findings contribute to research on climate change adaptation decision making both as a function of intra-individual processes such as knowledge, attitudes; and extra-individual factors like policies, infrastructure, information, forecasts etc. along with socio-economic contributory factors which deserve due attention in the light of scaling up adaptations.

The Chalanbeel is the main wetland of Northwestern region of Bangladesh. It is not only the source of water but also one of the main sources of occupation for thousands of people. It supplies fresh water as well as abundant of aquatic resources. This wetland is the large source of native fishes. It plays a vital role to keep the environment of the surrounding vast region balanced. It makes the land fertile, alluvial and alive for whole the year round. It is also a large reservoir of biological diversity of this region. Recently the aggression of man on this great beel increases in such a rate that the overall environment of this wetland fall in a crisis. It is going to loss its tradition and pride of her resources. Specially the aggression of settlement and road construction along the wetland hampered the natural characteristics. Reach it and an investigation was conducted to study the overall condition of the wetland. The observation indicates horror news for both the environment and its inhabitant of the surrounding area. Soils under lower Natore- Rajshahi region of Bangladesh with a view to evaluate the agricultural potentiality, environmental condition and their management options. The studied wetlands were nutritionally very productive. It is believed that the soils of this area became enriched by siltation during flooding. Soil textural condition is very much appropriate for rice production in these basin floodplains. The content of nitrogen and boron is low. Probably, the denitrification process leads to the loss of nitrogen in these soils; other nutrients seem to be in balanced condition for the successful growth of deep water aman and boro rice. High yielding boro rice got preference over broadcast aman and aous as major rice crops in the area. Availability of irrigation water in the dry periods and deep inundation level in the monsoon may be the main cause of such cropping pattern. Recently a problem is found that is the gradual decreasing of crop production in these areas. Both soil fertility and water table deterioration is noticed as the main causes of this alarming news for North Bengal. As this area is consider as the rice production zone of Northern region of Bangladesh. Over pumping of water during dry season is also a cause to deteriorate the environmental balanced of this wetland. For the betterment of grater environment of this area it is essential to take necessary step to stop all kind of human aggression on wetland. Public awareness should increase about the matter.
