Remote sensing and census based assessment and scope for improvement of rice and wheat water productivity in the Indo-Gangetic Basin por Cai, X.L., Sharma, Bharat R.

“…WP variability generally follows the same trend as shown by crop yield disregarding climate and topography changes. Sum of rice-wheat water productivity, however, exhibits different variability leading to better understanding of irrigation water management as wheat heavily relies on irrigation. …”

Institutions for Agricultural Mitigation: Potential and Challenges in Four Countries por Bryan, Elizabeth, De Pinto, Alessandro, Ringler, Claudia, Asuming-Brempong, Samuel, Bendaoud, Mohamed, Artur, Luis, Givá, Nicia, Asenso-Okyere, Kwadwo, Sarpong, Daniel Bruce, El-Harizi, Khalid, Mai, Nguyen Ngoc, Anh, Dao The, van Rheenen, Teunis, Ferguson, Jenna

“…The agriculture sector has great potential to contribute to the mitigation of greenhouse gas emissions through changes in agricultural management and land use. However, the technical potential for agricultural mitigation has yet to translate into actual emission reductions due to considerable constraints to the generation of emission offsets through agricultural projects. …”

Supplementation with Gliricidia sepium and Leucaena leucocephala on voluntary food intake, digestibility, rumen fermentation and live weight of crossbred steers offered Zea mays st... por Abdulrazak, S.A., Muinga, R.W., Thorpe, W.R., Orskov, E.R.

“…Twenty intact and five fistulated crossbred steers were used in two experiments to examine the effect of supplementing maize stover with Gliricidia sepium or Leucaena leucocephala forage on intake, rumen fermentation, microbial protein supply and live weight changes. The basal diet plus 1 kg maize bran was offered alone or supplemented with 7.5, 15, 22.5 or 30 g DM/kg W to the quare root of 0.75 of gliricidia (experiment 1), and with either 15 or 30 g DM/kg W to the square root of 0.75 of gliricidia or leucaena forage (experiment 2). …”

Financing market-oriented dairy development. The case of Ada'a - Liben Woreda Dairy Association, Ethiopia por Tegegne, Azage

“…The dairy industry needs to be optimised through organising milk production, processing, preservation and marketing in a well-coordinated way. With the recent changes in government policies featured by liberalisation and encouragement of the private sector to participate in the development of almost all aspects of the national economy, there exist immense opportunities to develop and improve the agricultural sub-sector. …”

Species diversification, livestock production and income of the poor in the Indian State of Andhra Pradesh por Akter, S., Farrington, John, Deshingkar, P., Rao, L., Freeman, H.A.

“…Poorer households depend disproportionally on livestock. Important changes were noted; the average size of any single species declined considerably in the five year period beginning from 1996/7, the number of farms keeping the species rose in the 1996/7 to 2001/2 period but dropped in the recent 2001/2 to 2003/4 period. …”

Farmers' perceptions of the impacts of tsetse and trypanosomosis control on livestock production: Evidence from southern Burkina Faso por Kamuanga, M., Sigue, H., Swallow, B.M., Bauer, B., D'Ieteren, G.D.M.

“…In the absence of health and productivity monitoring, data were collected in single-visit surveys in order to generate quantitative estimates of relevant reproductive performance variables for cattle and to assess changes in the inputs used and outputs produced. The results indicate a 25 percent increase in herd size and an increase in the number of oxen from 0.1 to 1.1 per household; a reduction in mortality from 63.1 percent to 7.1 percent and reductions in the rates of abortions and stillbirth of 55.9 percent and 51.3 percent, respectively; and an increase in the rate of live births of 57.6 percent and in the milk yield from 0.2 to 2.2 litres/cow per day in the dry season. …”

Operationalizing inclusive innovation: Lessons from innovation platforms in livestock value chains in India and Mozambique por Swaans, Cornelis P.M., Boogaard, Birgit K., Bendapudi, R., Taye, H., Hendrickx, Saskia C.J., Klerkx, Laurens

“…In addition to various structure and process components of inclusive innovation known from the literature, the study shows the importance of social organization, representation, and incentives to ensure a ‘true’ participatory innovation process, which is based on demand and embedded in the context; incremental change through so-called innovation bundles (i.e. combination of technical, organizational and institutional innovations) and reflexive learning (systematically challenging constraining factors) are critical to this. …”

Carbon footprints of Indian food items por Pathak, Himanshu, Jain, Niveta, Bhatia, Arti, Patel J, Aggarwal, Pramod K.

“…A non-vegetarian meal with mutton emitted GHG 1.8 times of a vegetarian meal, 1.5 times of a non-vegetarian meal with chicken and an ovo-vegetarian meal and 1.4 times a lacto-vegetarian meal. Change in food habit thus could offer a possibility for GHG mitigation.…”

“…Advances in both fields are currently used to improve process descriptions in biogeochemical models, which may eventually be used not only to test our current process understanding from the microsite to the field level, but also used as tools for up-scaling emissions to landscapes and regions and to explore feedbacks of soil N2O emissions to changes in environmental conditions, land management and land use.…”
