Water Tension

Water footprints (WFs) of rice are quite higher viz. 992 billion cubic metres per year (Gm3 yr−1) than from the other cereals which further responsible for the lower water productivity. Out of global WFs for crop production viz. 7404 Gm3 yr−1 corresponds to 78 % green, 12 % blue, and 10 % grey water, respectively. Around 3000-4000 litres of water required for one kg of rice grains and conventional puddle transplanted flood irrigations responsible for this. Therefore, there is an urgent need to cut down rice WFs share. Over irrigated pounded water under conventional puddle transplanted rice responsible for the emissions of the green house gases in atmosphere, which further has its own complications. With time, due to excessive withdrawals of the underground water, the water table is declining at a faster rate and seems to be beyond the reach of the middle class rice farmers. Rice water productivity declining day by day due to huge water demand of rice crop followed by reduced yields. A major share of the applied irrigation water lost/evaporate in the atmosphere. Soil water tension controls the soil moisture dynamics and directly linked to the plant need based approach. Being a kharif crop, rice season faces harsh summers and where evaporative demands of atmosphere intensified to many folds and thus, irrigation water has to be applied frequently. Annually additional water of worth US $ 39 million is withdrawn in NW Indian Punjab state for feeding crops, particularly rice. Tensiometer is the only instrument provided to the rice farmers for applying irrigation water judiciously based on the plant need which further cut down WFs from 18 to 22%. This practise where on one side saves irrigation water, improves declining land as well as water productivity of rice, also controlled the emissions of GHGs from the soil.

The study was carried out to examine the effect of agricultural transformation on the beneficiary’s productivity and poverty of rice farmers in Kano State Nigeria. A multi-stage sampling method was employed to select 571 respondents for the study. Data were collected through structured questionnaires on respondent’s income, input and output quantities as well as their expenditures. Data were analysis using descriptive statistics, Foster-Greer-Thorbecke (FGT), Propensity score matching and LATE model. Results from the study shows that respondents productivity revealed a significant difference of about 127 kg/ha in rice productivity between participants and non-participants. Also, the LATE estimates revealed an average treatment effect ATE0 of about 222.98kg/ha. Furthermore, the project had a significant effect N11, 321.4 on the participant’s consumption expenditure than the non-participants N9980.60. Moreover, participants were, able to increase their household total expenditures by N34780 per annum. Fluctuations of input/output prices insect pests and inadequate extension visits were all the major constraints faced by the farmers. It was recommended that farmers’ information and sensitization system should be overhauled and improved. Also, attention should be given to well organize extension visits for the farmers from stake holders

This article argues that the number of unprosecuted human traffickers is growing in Cameroon. This article aims to examine Cameroonian government officials, prosecutors and judiciary attitudes to human trafficking laws, which endanger Cameroonians. This article is an empirical study of victims of human trafficking. It takes an objective look at Cameroon's anti-trafficking law that criminalises the trafficking of adults and children. It is evident that societal discrimination towards the North West region, lack of opportunities for free education or to a trade post-primary school and the lack of enforcement of the anti-trafficking law are making combating human trafficking an arduous task.

Efficient Water Use

The deficit of the irrigation water requires irrigation technologies with more efficient water use. For cucumbers, the most suitable is the drip irrigation technology. For establishing of the appropriate irrigation schedule of cucumbers under the soil and climate conditions in the village of Chelopechene, near Sofia city, the researchеs was conducted with drip irrigation technology, adopting varying irrigation schedules and hydraulic regimes - from fully meeting the daily crops water requirements cucumbers to reduced depths with 20% and 40%. It have been established irrigation schedule with adequate pressure flows in the water source, irrigation water productivity and yields of in plastic unheated greenhouses of the Sofia plant.
