"This research will create a paradigm shift in sustainable crop production and provide new opportunities for using intelligent operating systems to improve pest control applications and reduce yield gaps
," Sharda said.
The purpose of such a policy should be to bridge the yield gaps
in all major and minor crops in the minimum possible time, economize the use of water and arable land for agriculture, enhance livestock productivity and sustainability, ensure fuller exploitation of horticulture, strike a balance between productivity boost and its shortand long-term environmental impact, and increase the perunit value of agro-based exports.

ISLAMABAD -- Senior Agriculture Economist, World Bank, Pakistan, Hans GP Jansen, has said that in Punjab yield gaps
in major crops is hazardously high and yields are 30-50percent low in the neighbouring countries of the region, reasoning that Pakistan is at the bottom of agricultural R and D spending which is lower in South Asia .
Among their topics are integrated pest management in sustainable palm oil production, developments in disease-resistant oil palm varieties, bioactive compounds in oil palm, life cycle assessment of palm oil in practice: the example of Malaysia, balancing oil palm cultivation with forest and biodiversity conservation, and closing yield gaps
for small-scale and medium-scale oil palm producers: improving cultivation practices.
More generally, one goal of sustainable agriculture should be to ensure that annual yield growth of the world's most important staple crops rise as fast as or faster than the demand, by closing existing yield gaps
and raising the yield ceiling.

in rainfed cropping systems: a case study of wheat in Australia.
He briefed that FAO is working on a baseline atlas of current soil fertility practices, disaggregated by farm size and cropping systems in Pakistan to understand required soil fertility management changes for sustainable agricultural intensification and to fill the yield gaps
by balanced use of fertilizers.
Programmes for narrowing the yield gaps
with more focus on smallholders
One scenario investigated by the team is on the supply side: the closing of 'yield gaps
Balisacan and associates highlighted the need for increased budget in rice R&D by closing the yield gaps
. The authors noted yield gaps
in rice are attributable to weeds, pests, and diseases, which can very well be addressed by stepping up initiatives on rice research.
